High throughput screening (HTS) facilitates screening large numbers of compounds against a biochemical target of interest using validated biological or biophysical assays. In recent years, a significant number of drugs in clinical trails originated from HTS campaigns, validating HTS as a bona fide mechanism for hit finding. In the current drug discovery(More)
DNA ligase is an enzyme essential for DNA replication, repair, and recombination in all organisms. Bacterial DNA ligases catalyze a NAD(+)-dependent DNA ligation reaction, i.e., the formation of a phosphodiester bond between adjacent 3'-OH and 5'-phosphate termini of dsDNA. Due to their essential nature, unique cofactor requirement, and widespread existence(More)
Lung cancer accounts for the most cancer-related deaths. The identification of cancer-associated genes and the related pathways are essential to prevent many types of cancer. In this paper, a more systematic approach is considered. First, we did pathway analysis using Hyper Geometric Distribution (HGD) and significantly overrepresented sets of reactions(More)
"The Third International Meeting on Genetic Disorders in the RAS/MAPK Pathway: Towards a Therapeutic Approach" was held at the Renaissance Orlando at SeaWorld Hotel (August 2-4, 2013). Seventy-one physicians and scientists attended the meeting, and parallel meetings were held by patient advocacy groups (CFC International, Costello Syndrome Family Network,(More)
