Study reveals cancer-linked epigenetic effects of smoking ...
“DNA methylation is a type of epigenetic change that can result in tumor suppressor genes being inactivated,” said Dr Ma. “Methylation of p16 has been frequently associated with the development of cancer in many parts of the body.” Because the women were all taking part in a study of cervical neoplasia, Dr Ma used cells from cervical smears to test for methylation of p16. Her group found that women who took up smoking during the study were more than three times as likely (odds ratio of 3.67) to acquire p16 methylation. “Our study showed that compared with never-smokers, women who [more...]

In most cells, 100-1000 Okazaki fragments are produced for each replicative DNA polymerase present in the cell. For fast-growing cells, this necessitates rapid recycling of DNA polymerase on the lagging strand. Bacteria produce long Okazaki fragments (1-2 kb) and utilize a highly processive DNA polymerase III (pol III), which is held to DNA by a circular sliding clamp. In contrast, Okazaki fragments in eukaryotes are quite short, 100-250 bp, and thus the eukaryotic lagging strand polymerase does not require a high degree of processivity.

Genetic drift , selection , migration, etc., are parameters which are used to construct models that allow us to generate predictions and obtain deeper insight. The discovery of DNA and the elucidation of the biophysical substrate which constrains the modes of inheritance in a concrete manner opened up the startling vistas of molecular evolutionary genetics. Generally, gene mutations can disrupt an entire protein, but in colon cancers, only half the APC protein is lost, while the other half remains, Ahmed explains.

However, the wild bacterium lacks an enzyme called a "citrate permease" which can transport citrate from outside the cell through the cell's membrane into its interior. So all the bacterium needed to do to use citrate was to find a way to get it into the cell. The rest of the machinery for its metabolism was already there. As Lenski put it, "The only known barrier to aerobic growth on citrate is its inability to transport citrate under oxic conditions." Bacteria evolving in the lab? Nope.

Cancer cells with high levels of ERCC1 protein are better able to repair the DNA adducts before the cell can die, and thus are resistant to platinum compounds. In contrast, NSCLC cells with low levels of ERCC1 have a worse prognosis but are more sensitive to platinum chemotherapy. This finding has led to a number of clinical trials that attempt to determine ERCC1 levels ahead of time and use the platinum only when the levels are low. These trials in advanced NSCLC will be explored more in a separate chapter, and were reviewed in early stage NSCLC by Dr. Wakelee. Another DNA repair protein [more...]

Part of the reason for this is if one decides to take into account the plethora of species-specific DNA insertions and deletions ("indels") that are present along any segment compared between chimp and human, the percentage of identity drops. Another reason is that duplications, inversions, translocations, and transpositions at all scales uniquely characterize the two genome sequences -- these have to be untangled before aligning the sequences in order to measure their similarity. Also, the 99% identity figure is often derived from protein-coding regions that only comprise about 1.5% of the [more...]
