DNA Bending Propensity in the Presence of Base Mismatches: Implications for DNA Repair

Jitendra Narayan — Mon, 19 Aug 2013 16:01:44 -0500

Understanding how the human body recognizes damaged DNA and initiates repair fascinates Michael Feig, professor of biochemistry and molecular biology at Michigan State University. Feig studies the proteins MutS and MSH2-MSH6, which recognize defective DNA and initiate DNA repair. Natural DNA repair occurs when proteins like MutS (the primary protein responsible for recognizing a variety of DNA mismatches) scan the DNA, identify a defect, and recruit other enzymes to carry out the actual repair.

Results from computer simulations show that it is energetically less expensive to bend mismatch-containing, defective DNA (G:T, C:C, C:T, G:A, G:G, T:T, A:A, A+:C) vs. non-defective DNA (containing A:T or G:C base pairs). DNA repair mechanisms likely take advantage of this feature to detect defective DNA based on an increased bending propensity.

Tivicay® (dolutegravir) 50-mg tablets for HIV-1

Neel — Fri, 16 Aug 2013 09:00:15 -0500

FDA has approved Viiv Healthcare’s integrase inhibitor Tivicay® (dolutegravir) 50-mg tablets, for use with other antiretroviral agents in treating HIV-1 infection. ViiV Healthcare is an HIV therapeutics company established in 2009 by GlaxoSmithKline and Pfizer.

Tivicay is indicated for infected adults, both treatment-naive and treatment-experienced, including those treated with other integrase strand transfer inhibitors; as well as for children aged 12 years and older weighing at least 40 kg (approx. 88 lbs). The drug - which was used without a pharmacokinetic boosting agent - interferes with one of the enzymes necessary for HIV to multiply, and can be taken with or without food and at any time of day.

Cancer's origins revealed

Jitendra Narayan — Thu, 15 Aug 2013 13:06:56 -0500

Researchers have provided the first comprehensive compendium of mutational processes that drive tumour development. Together, these mutational processes explain most mutations found in 30 of the most common cancer types. This new understanding of cancer development could help to treat and prevent a wide-range of cancers.

PhylomeDB

Poonam Mahapatra — Mon, 12 Aug 2013 11:55:39 -0500

PhylomeDB is a public database for complete collections of gene phylogenies (phylomes). It allows users to interactively explore the evolutionary history of genes through the visualization of phylogenetic trees and multiple sequence alignments.

Moreover, phylomeDB provides genome-wide orthology and paralogy predictions which are based on the analysis of the phylogenetic trees. The automated pipeline used to reconstruct trees aims at providing a high-quality phylogenetic analysis of different genomes , including Maximum Likelihood or Bayesian tree inference, alignment trimming and evolutionary model testing. PhylomeDB includes also a public download section with the complete set of trees, alignments and orthology predictions.

Webinar: Wednesday 21 August 2013 at Noon EDT

Jitendra Narayan — Sun, 11 Aug 2013 19:31:56 -0500

This webinar will describe the use of combinatorial pooling to reconstruct gene sequences within BACs. Recent work in barley has shown that this level of sequence knowledge is sufficient to support critical end-point objectives such as map-based cloning and marker-assisted breeding.
