Free Online Guides: New role for master regulator in cell ...
Unlike genetic changes, which involve a change or mutation in DNA sequence, epigenetic changes in the nucleus leave the DNA sequence unaltered but modify the histone proteins, which comprise the backbone of the chromosome. Histones are proteins found in the nucleus that package and order DNA into structural units. Epigentic changes alter how DNA folds in chromosomes, changing how accessible genes are to regulatory proteins and enzymes that copy genes into RNA messages."Epigenetics is the study of how factors outside of actual DNA interact with, but not alter, genes. It is turning out, through [more...]

Genetic Test Kits-Journey Down the Rabbit Hole | generationhealth.com
A recent news story about the FDA’s halt to the sale of genetic test kits at Walgreens and CVS has opened the door to a public discussion on the issue of gene mapping and genetic testing. For instance, is this a case of science moving at such a fast pace that social policy and ethical determinations have not had a chance to catch up? Many think so. Testing genes within DNA for mutations that are associated with specific diseases has many ramifications that need to be addressed before such technology is used outside the realm of scientific exploration and discovery. One of the big issues [more...]

Traditionally, pregnancy-related genetic testing has been limited to prospective parents whose family history or ethnicity suggests that they may be at an increased risk for a particular genetic disease. One example of this is genetic screening for Tay-Sachs disease mutations in people of Ashkenazi Jewish origin. The problem with this approach is that it relies on self-reported ethnicity and family history, which can be incomplete or misleading. Additionally, the ethnic distribution and prevalence of many genetic disease-causing mutations is not known. The Simple Solution Using only a [more...]

Autism and schizophrenia: Scientists measure gene mutation rate ...
Mutations are alterations of the cell’s DNA that can occur because of errors in the DNA replication, which happen prior to cell division. Once DNA is changed, this mutation is passed down to a next generation. A mutation that is newly formed and therefore not inherited from either parent is called a de novo mutation. More information: The paper, “Direct Measure of the de novo Mutation Rate in Autism and Schizophrenia cohorts,” published in the American Journal of Human Genetics, was authored by Philip Awadalla, et al. http://www.cell.com/AJHG Source: [more...]

FuturePundit: Dopamine Genes Influence Sensation Seeking
Derringer used a kind of mutation in DNA called a single-nucleotide polymorphism, or SNP. A SNP is a change in just one "letter" of the DNA. Note that single letter differences are just one of a few genetic differences possible. But SNPs are cheaper to test for. So they get more research attention. She started by picking eight genes with various roles related to the neurotransmitter dopamine, which has been linked to sensation seeking in other studies. She looked at group of 635 people who were part of a study on addiction. For each one, she had genetic information on 273 SNPs known to appear [more...]

Along with other antioxidant nutrients, selenium helps to block reactions that lead to free radical formation; free radicals which can cause DNA mutation leading to cancer. Glutathione peroxidase is one of the body's most powerful antioxidant enzymes, used by the liver to detoxify a wide range of potentially toxic molecules. Selenium also protects against cancer by inducing DNA repair and synthesis in damaged cells, repairing free radical damage that has already occurred. It inhibits the spread of cancer cells and induces tumor cells' natural self-destruct sequence. Plus, selenium is [more...]

FAN1 glommed onto sites of the DNA damage.

The mitochondrial DNA genealogy is the study of a person’s mother’s family line of maternal ancestors. This DNA is passed down from mother to each of her children exactly as she has it, with no mutations, except in the very rare instances. Because of the traditions in our society of the wife taking her husband’s last name, a surname genealogy trace of the female line of the family tree is more difficult. On the flip side, since this DNA strand is more stable than the Y DNA, more conclusive results can be determined for the testing of it. The mt-DNA is sometimes referred to as the Full [more...]

Before cells are divided, the chromosomes duplicate first; this is what we call replication of DNA. This is the division of cells which results in two cells that have to contain the same information like their mother-cell. There are four nitrogenous bases within the DNA molecule. Those are: Adenine, Cytosine, Thymine and Guanine. Genes are composed of bases. In case of DNA damaging, the sequence of DNA will be changed. This happens when there is mutagen factor involved. These mutagens are highly radioactive. The damage that occurs as a result of the radiation is determined by the mutagen [more...]

Other mutations were consistent with some in vitro activities of mammalian translesion DNA polymerase η: tandem base substitutions, strand slippage, and small insertions/deletions. The nature of substitution patterns shows that DNA lesions at shark Ig genes recruit DNA repair factors with a species-specific repertoire of activities. We speculate that the tandem [more...]
