CANCER GENES - 'METHYL MAGNET'

Medical researchers have discovered a new type of mechanism causing cancer susceptibility, showing that tiny changes in some anti-cancer genes can act as magnets to attract modifying "biochemical tags", effectively switching them off and predisposing families to an increased risk of the disease.

The study and its findings are reported in the leading international journal Cancer Cell.

The researchers, from the University of New South Wales (UNSW), believe a tiny spelling mistake involving a single letter in the DNA sequence near the start of the genes is what attracts the biochemical tag – known as methylation.
This biochemical tag directly impacts on our DNA, by switching genes off.
"Methylation sits on top of our DNA, and provides the instructions to turn the gene off," explains study co-leader, Dr Megan Hitchins, from UNSW's Lowy Cancer Research Centre.
In one well-known cause of hereditary cancer, changes in the cancer-prevention gene MLH1 are passed from parent to child creating up to 80 percent risk of developing bowel, uterine and other cancers. However, some families with hereditary cancer have no spelling mistakes in MLH1, but instead have methylation sitting on the gene.
"When the methylation attaches to the MLH1 gene in these families, it causes it to be completely switched off and as a consequence cancer develops," says study co-leader and head of the adult cancer program at the Lowy Cancer Research Centre, Professor Robyn Ward. "But until now, we did not understand how these methylation tags were being passed from parent to child."
In the study the researchers looked at three generations of a large family, who had cancer at a young age, but in whom no spelling mistakes typical of this hereditary cancer syndrome had been found. Strikingly several members of the family from all generations had methylation tags on their gene.
"In this family, biochemical tags attached to the MLH1 gene were present in all three generations. This was intriguing since these markers are usually removed during the production of eggs and sperm," Dr Hitchins said.
"What we found was that a subtle change near the gene was acting like a magnet to attract methylation. So it was not the methylation itself that was being passed from parent to child, but rather the DNA change, and this acted as a methyl magnet," she said.
The methylation was cleared away in the sperm and eggs and then recreated in each new generation, the researchers said.
Professor Ward said the discovery pinpointed the cause of cancer in this family and it offered new options for genetic diagnosis, counselling and early interventions in other families at risk of hereditary cancers.
The team is also exploring the use of certain drugs to clear away the methylation in cancer to switch the anti-cancer genes back on again. In the future these drugs may be used to create a more targeted approach to cancer treatment and possibly prevention.

DNA and RNA arrived from space.

For some reason or another, all of us like to believe that Earth is special - after all, our planet is the only one able to sustain life that we know of. Indeed, Earth is special in its own way, but life would not have been possible without the significant contribution of material coming form space. In fact, a new study shows that the compounds making up DNA and RNA actually originated in space, not on Earth as previously thought, and were brought here by meteorite fragments and other similar objects.

"Because meteorites represent leftover materials from the formation of the solar system, the key components for life - including nucleobases - could be widespread in the cosmos. As more and more of life's raw materials are discovered in objects from space, the possibility of life springing forth wherever the right chemistry is present becomes more likely," said Mark Sephton, professor of Earth science and engineering at Imperial College London and co-author of the study."We believe early life may have adopted nucleobases from meteoritic fragments for use in genetic coding which enabled them to pass on their successful features to subsequent generations," said the leader of the study, Zita Martins of the Department of Earth Science and Engineering at Imperial College London.

In 1969, a meteorite fragment, known today as the Murchison meteorite, crashed in the Australian outback. A thorough analysis, following its discovery, showed that it contained uracil and xanthine molecules (nucleobases), which are building blocks for genetic materials made up of a heavy carbon isotope. On Earth, such molecules contain only light carbon isotopes.

However, these two molecules are just a few of many others found in the respective fragment. "There are about 70 different amino acids in the Murchison meteorite. About six or so are the same kinds of amino acids associated with life on Earth," said David Deamer from the University of California.

The uracil molecule is one of the four bases for the RNA molecule, therefore it is invaluable to life. Deamer points out that, although these molecules have been proven to originate in space, they could have been developed on Earth just as well. Nevertheless, the proportion of molecules originating only in space or only on Earth is currently unknown.

"We don't know the answer yet. Most people would say that both contributed to the organic compounds available on Earth, but we don't know with certainty how much of one compared to the other," said Deamer.

between 3.8 and 4.5 billion years ago, when primitive life first appeared, the Earth and Mars could have been literally bombarded with meteorites similar to the Murchison, thus studying the impact they would have had on different planets could reveal how life evolved in the solar system.

UBC Scientists extracted dilluted and contaminated dna

University of British Columbia researchers have developed a new way to extract DNA and RNA from small or heavily contaminated samples that could help forensic investigators and molecular biologists get to “the truth.”
“By exploiting the physical traits of DNA – electric charge, length and flexibility – we’ve been able to extract DNA from samples that would otherwise not produce enough clean DNA for analysis,” says UBC Biophysics Prof. Andre Marziali.
The technique is being commercialized through Boreal Genomics, a UBC spin-off company, and is expected to have broad applications from basic life-science research to forensic sample analysis, bio-defence and pathogen detection for food safety and clinical diagnostics.
The research team, which includes scientists from UBC and BC Cancer Agency’s Genome Science Centre, details the technique in this week’s Proceedings of the National Academy of Science.
Extracting DNA by conventional methods – which rely on the molecules’ chemical properties – has proven challenging when there are only trace amounts of DNA or when the source sample has contaminants with similar chemical traits.
“We’ve found that DNA and RNA respond to electric fields in a way that is very different from other molecules,” says Marziali. “By exploiting this unique property, we were able to extract high quality DNA from a highly contaminated sample from the Athabasca oil sands.”
The team also successfully tested the technique on samples provided by the RCMP.

Cystic Fibrosis

Cystic Fibrosis (CF) is one of the most common genetic diseases in the United States. It is caused by a change in a gene called CFTR. A December 2009 report by "Anesthesia & Analgesia" summarizing the genetic basis of CF noted that there are more than 1,000 possible changes in the CFTR gene that can cause CF, and that approximately one of every 29 Caucasian Americans have a mistake in one copy of their CFTR gene. These people do not have CF since they still have one good copy of the CFTR gene. However, when both parents have one damaged CFTR gene, they have a 25-percent chance that any child of theirs will inherit one bad copy of CFTR from each parent and have cystic fibrosis. As of 2010, there is no cure for CF, but a number of therapies have been developed that can treat the symptoms associated with cystic fibrosis.

DNA REPLICATION

Hello Friends, Today we have a look on "DNA REPLICATION". What does it means.

At first we gone look on Biochemical reaction for Dna Replication.

DNA archetype begins with the "unzipping" of the ancestor atom as the hydrogen bonds amid the abject pairs are broken. Once exposed, the arrangement of bases on anniversary of the afar strands serves as a arrangement to adviser the admittance of a commutual set of bases on the fiber actuality synthesized.The new strands are accumulated from deoxynucleoside triphosphates.Anniversary admission nucleotide is covalently affiliated to the "free" 3' carbon atom on the pentose (figure) as the additional and third phosphates are removed calm as a atom of pyrophosphate (PPi). The nucleotides are accumulated in the adjustment that complements the adjustment of bases on the fiber confined as the template.

Thus anniversary C on the arrangement guides the admittance of a G on the new strand, anniversary G a C, and so on.When the action is complete, two DNA molecules accept been formed identical to anniversary added and to the ancestor molecule.

Role of Enzymes......

A allocation of the bifold braid is unwound by a helicase. A atom of a DNA polymerase binds to one fiber of the DNA and begins affective forth it in the 3' to 5' direction, application it as a arrangement for accumulating a arch fiber of nucleotides and reforming a bifold helix. In eukaryotes, this atom is alleged DNA polymerase basin (δ). Because DNA amalgam can alone action 5' to 3', a atom of a additional blazon of DNA polymerase (epsilon, ε, in eukaryotes) binds to the added arrangement fiber as the bifold braid opens. This atom charge amalgamate alternate segments of polynucleotides (called Okazaki fragments). Another enzyme, DNA ligase I again stitches these calm into the backward strand.

Dna Replication is semi conservative.

When the archetype action is complete, two DNA molecules — identical to anniversary added and identical to the aboriginal — accept been produced. Anniversary fiber of the aboriginal atom has remained complete as it served as the arrangement for the amalgam of a commutual strand. This approach of archetype is declared as semi-conservative: one-half of anniversary new atom of DNA is old; one-half new. Watson and Crick had appropriate that this was the way the DNA would about-face out to be replicated. Proof of the archetypal came from the abstracts of Meselson and Stahl
Follow this link to see the proof...http://users.rcn.com/jkimball.ma.ultranet/BiologyPages/M/Meselson_Stahl.html

Another important point is the SPEED OF REPLICATION.

Among Bacteria

The distinct atom of DNA that is the E. coli genome contains 4.7 x 106 nucleotide pairs. DNA archetype begins at a single, anchored area in this molecule, the archetype origin, gain at about 1000 nucleotides per second, and appropriately is done in no added than 40 minutes. And acknowledgment to the attention of the action (which includes a "proof-reading" function), the job is done with alone about one incorrect nucleotide for every 109 nucleotides inserted. In added words, added generally than not, the E. coli genome (4.7 x 106) is affected after error!

Among Eukaryotes

The boilerplate animal chromosome contains 150 x 106 nucleotide pairs which are affected at about 50 abject pairs per second. The action would booty a ages (rather than the hour it absolutely does) but for the actuality that there are abounding places on the eukaryotic chromosome area archetype can begin. Archetype begins at some archetype origins beforehand in S appearance than at others, but the action is completed for all by the end of S phase. As archetype nears completion, "bubbles" of anew replicated DNA accommodated and fuse, assuredly basic two new molecules.

We now Look on Control of Replication....

With their assorted origins, how does the eukaryotic corpuscle apperceive which origins accept been already replicated and which still anticipate replication?

An observation: When a corpuscle in G2 of the corpuscle aeon is alloyed with a corpuscle in S phase, the DNA of the G2 basis does not activate replicating afresh alike admitting archetype is proceeding commonly in the S-phase nucleus. Not until mitosis is completed, can freshly-synthesized DNA be replicated again.

Two ascendancy mechanisms accept been articular — one absolute and one negative. This back-up apparently reflects the acute accent of absolute archetype to the candor of the genome.

It has two kind of controls a positive and a negative.

DNA HELPS TO FIND CRIMINALS

DNA is also used to find the criminals of rapist and murderers.It was the "fingerprint of the 21st century".The use of DNA evidence has not kept pace with its potential. From many years, DNA evidences from hundreds of thousands of rape and murder cases that was collected by police but never sent to labs for analysis. As this evidence backlog, one of the biggest problem to getting rapists out of the streets, became overwhelming for states and other local peoples, RAINN concluded that a federal solution should be implemented. To help to launch the effort. Also RAINN led a successful national campaign to educate the media and lawmaker peoples about the backlog of unanalyzed DNA casework and bring this enormous problem to public attention. RAINN's president and founder, Scott Berkowitz, also testified before the U.S. Congress regarding DNA testing backlog.

INFORMATION ON DNA

Deoxyribonucleic acid (DNA)   is a nucleic acid present in the cells of all living organisms. It is   often referred to as the “building blocks of life,” since "DNA"  encodes the genetic material which determines what an organism will  develop into. In addition to maintaining the genetic blueprints for its  parent organism, DNA also performs a number of other functions which are critical to life.
This   nucleic acid was first identified in 1889, when researcher Friedrich   Miescher found a substance he called “nuclein” in human cells. In the   early 20th century, several researchers including Phoebus Levene and   William Astbury performed additional research on nuclein, beginning to   understand its components, structure, and role in life. A seminal   article published in Nature in 1953 by James Watson and Franklin Crick is often cited as the breakthrough moment in DNA research, as it correctly posited the distinct structure of DNA, with significant help from scientist Rosalind Franklin.

GENOMIC CODE CRACKING - ATOMIC LEVEL GENE DECODING RESULTS

Hi... Today we seen some information regarding genomic code cracking that is atomic level gene decoding results that is revealed.Freinds Dr. Paul F. Agris, professor of biochemistry at NC State, and academic colleagues from England and Poland show clear evidence for 1966 “Wobble Hypothesis” offered by Francis Crick who was the co-founder of the DNA molecule and its double-helix structure, and Dr. Agris’ own “Modified Wobble Hypothesis” posed in 1991.

The scientists used x-ray crystallography of the cell’s protein-manufacturing unit, the ribosome, to provide a visual snapshot of the decoding process.

This research is published in the December 2004 edition of Nature Structural and Molecular Biology.

The Wobble Hypothesis was Crick’s attempt to make sense of how the cell decodes the genetic information of DNA – the molecule that constitutes all the genetic information in a cell – and then, from that information the biologically active proteins comes to an existence, Dr. Agris results.

The term DNA has 61 three-letter codes that are translated by transfer RNA (tRNA) into amino acids; also proteins are made of amino acids. But the facts is that there are only 20 natural amino acids. Squaring the disparity between the number of codes and the number of amino acids – there are three times as many codes as there are amino acids – became a hurdle for Crick and other early geneticists, Dr. Agris explanation.

Also Crick attempted to clear this hurdle with the Wobble Hypothesis. He based this theory on the first report of a tRNA molecule’s chemical structure discovered by Robert Holley in 1963. Normally, RNA molecules are composed of four nucleosides: adenosine, guanosine, cytosine and uridine (A,G,C,U). But the tRNA molecule which Holley studied included a modified nucleoside called inosine (I), Dr. Agris says. By seeing this inosine in an important area of the tRNA molecule – an area that read the three-letter DNA codes when the cell synthesizes proteins – led Crick to believe that a single tRNA used inosine to read more than one code, and that therefore the 61 codes were decoded by fewer than 61 tRNAs.

Example, Dr. Agris used the amino acid alanine, which has four codes. Crick’s hypothesis would allow that only the two tRNA molecules could be capable to decode all four alanine codes.By using the modified nucleoside I in place of A, G, C or U, one tRNA may be able to read three codes, effectively “wobbling” the reading.

Twenty-five years after the Wobble Hypothesis, Dr. Agris proposed his Modified Wobble Hypothesis. It stated that modified nucleosides other than inosine would in some cases expand tRNAs ability to translate codes by wobbling to greater numbers of three-letter codes, whereas other modified nucleosides would restrict the wobble to only one or two codes.

According to the recent paper,Dr. Agris and colleagues already proved that Agris’ alteration to Crick’s hypothesis was correct: Cellular modification of tRNA alters chemistry and also structure in a manner critical for tRNA to decode more than one three-letter code.

And by using atomic-level resolution – in which researchers can distinguish atom from atom – and working with a tRNA specific for the amino acid lysine,Dr. Agris and his colleagues show modified nucleosides enabling tRNA to decode genomic information on the ribosome, the cell’s protein synthesis machinery.

Thus Specifically, it shows modifications enabling the decoding of two codes. One modification acts like a platform on which decoding takes place, and the other allows a novel chemical and physical interaction to occur between tRNA and the code,Dr. Agris said.

“This is the first visualization that modifications are critical for decoding the genome through wobble,” Said by Dr. Agris.

Dr. Agris says that 15 to 20 percent of tRNAs in all organisms require modified chemistries in order for codes to be properly read and protein synthesis to be successful.

“An understanding of how modified nucleosides enable and improve wobble recognition of the three-letter codes for protein synthesis opens the possibility of using modified nucleosides to expand the cells’ use of tRNA to make new proteins, or in new ways to target the protein synthesis machinery in pathogens,” Said by Dr. Agris.

Messenger RNA Synthesis

During transcription, RNA polymerase makes a copy of a gene from the DNA to mRNA as needed. This process is similar in eukaryotes and prokaryotes. One notable difference, however, is that prokaryotic RNA polymerase associates with mRNA processing enzymes during transcription so that processing can proceed quickly after the start of transcription. The short-lived, unprocessed or partially processed, product is termed pre-mRNA; once completely processed, it is termed mature mRNA.
Messenger ribonucleic acid, commonly called messenger RNA or mRNA, is an RNA molecule that encodes a chemical "blueprint" for the synthesis of a protein. Messenger RNA contains a copy of the genetic data contained on a strand of DNA. Ribosomal ribonucleic acid (ribosomal RNA or rRNA) helps to form the ribosome itself.
Same like messenger RNA (mRNA), ribosomal RNA does not transmit genetic information. Instead of this it combines with proteins to create a structure that systematically transforms mRNA into proteins.

DNA GENE DECODING SITES

The additional blazon of account now on the web that will appulse adoptions is the adeptness to break your child's DNA. Adoptive families will acquisition this armpit advantageous for abounding reasons. Your child's DNA is decoded, accouterment you with abundant admired information. The acquaintance is accompanying unsettling, anecdotic and empowering.

While these adaptation sites accommodate the befalling for DNA Acceptance Networking, that seems to be a by-product of their capital function, which is to break your DNA. For the acceptance world, casework like this accept amazing implications, including:

(i) In the majority of adoptions in the world, there is little or no advice about the bearing father. This includes calm adoptions, as able-bodied as adoptions from added genitalia of the world. Adaptation your child's DNA will accommodate you with cogent advice about the bearing ancestor and the bearing mother. The websites affirmation they acquiesce you to attending 20 or 40 years into the approaching at cogent DNA markers that will affect your child's bloom (such as pre-disposition to assertive diseases).
(ii) Once registered with some sites, you will be automatically brash over the abutting 10, 20 or 30 years, as medical science makes new discoveries and advances.
(iii) In some situations DNA adaptation may become accessible as allotment of pre-adoption medical and amusing advice about the child. Currently, parents accept bound medical information, photographs, and sometimes a video. Perhaps in the approaching a DNA besom will become allotment of this pre-adoption advice package.
(iv) As countries become added careful about whom may accept their accouchement (such as China) will they demand DNA tests of the adopting parents? Adopting Parents already accept to accumulation medical and lab letters as allotment of a abstracts for all-embracing adoption. Are DNA letters next?

These websites will accompany abundant opportunities, but additionally abundant quandaries. We will no best accept the botheration of not knowing, but instead accept the accountability of whether we demand to apperceive in the aboriginal place. We will apperceive whether our accouchement are agreeable to assertive ancestry or talents, athletics, music or languages, and we'll animate them to accompany assertive paths. I accept afresh declared these websites to clients, accompany and relatives. It is absorbing how abounding bodies accept said, "But do you absolutely demand to apperceive this information?". Clearly, some bodies would rather not apperceive and aloof let the approaching unfold.

This is a web-based account that helps you accept your DNA. Send in a sample of your child's saliva and see how the decoded genes announce your child's future. This armpit is partly adjourned by Google. The amount for a DNA assay is $999, and you will accept a address allegory about 600,000 DNA checkpoints.

At this time their account is alone accessible in the USA, Europe and Canada, although it will aggrandize in the approaching to added countries. In acknowledgment to my catechism to this armpit as to whether adopting parents could use it to accept the DNA decoded for a adolescent proposed to them for adoption, the acknowledgment was "Our account is not advised to be acclimated for abiogenetic screening purposes."

CANCER DUE TO RADIATION EFFECTS ON DNA

Cancer is produced if radiation does not annihilate the corpuscle but creates an absurdity in the DNA adapt that contributes to closing accident of ascendancy of corpuscle division, and the corpuscle begins adding uncontrollably. This aftereffect ability not arise for abounding years. Cancers induced by radiation do not alter from cancers due to added causes, so there is no simple way to admeasurement the amount of blight due to radiation. During the aeon advised by the Advisory Committee, abundant accomplishment was adherent to studies of ablaze animals and apparent groups of bodies to advance bigger estimates of the accident of blight due to radiation. This blazon of analysis is complicated by the array of cancers, which alter in radiosensitivity. For example, cartilage bottom is added acute than bark beef to radiation-induced cancer.

Large doses of radiation to ample numbers of bodies are bare in adjustment to account assessable increases in the cardinal of cancers and appropriately actuate the differences in the acuteness of altered organs to radiation. Because the cancers can action anytime in the apparent person's lifetime, these studies can booty seventy years or added to complete. For example, the better and scientifically best admired epidemiologic abstraction of radiation furnishings has been the advancing abstraction of the Japanese diminutive bomb survivors. Added important studies accommodate studies of ample groups apparent to radiation as a aftereffect of their activity (such as uranium miners) or as a aftereffect of medical treatment. These types of studies are discussed in greater detail in the area blue-blooded "How Do Scientists Actuate the Long-Term Risks from Radiation?"

WHAT IS DNA ?????

Hi friends today we share some information regarding "what is dna". Deoxyribonucleic acid "DNA" is a nucleic acid that contains the abiogenetic instructions acclimated in the development and activity of all accepted active bacilli and some viruses. The capital role of DNA molecules is the abiding accumulator of information. DNA is generally compared to a set of blueprints or a recipe, or a code, back it contains the instructions bare to assemble added apparatus of cells, such as proteins and RNA molecules. The DNA segments that backpack this genetics advice are alleged genes, but added DNA sequences accept structural purposes, or are complex in acclimation the use of this genetics information.

Chemically, DNA consists of two continued polymers of simple units alleged nucleotides, with backbones fabricated of sugars and phosphate groups abutting by ester bonds. These two strands run in adverse admonition to anniversary added and are accordingly anti-parallel. Attached to anniversary amorous is one of four types of molecules alleged bases. It is the arrangement of these four bases forth the courage that encodes information. This advice is apprehend application the genetics code, which specifies the arrangement of the amino acids aural proteins. The cipher is apprehend by artful stretches of DNA into the accompanying nucleic acerbic RNA, in a action alleged transcription.
DNA Structure

Within cells, DNA is organized into continued structures alleged chromosomes. These chromosomes are bifold afore beef divide, in a action alleged DNA replication. Eukaryotic bacilli (animals, plants, fungi, and protists) abundance best of their DNA central the corpuscle basis and some of their DNA in organelles, such as mitochondria or chloroplasts. In contrast, prokaryotes (bacteria and archaea) abundance their DNA alone in the cytoplasm. Aural the chromosomes, chromatin proteins such as histones bunched and adapt DNA. These bunched structures adviser the interactions amid DNA and added proteins, allowance ascendancy which genitalia of the DNA are transcribed.
