The aetiology of juvenile nasopharyngeal angiofibroma (JNA) is largely unknown. In this study, we have investigated the expression of glutathione S transferase M1 (GSTM1) gene in angiofibroma. The GSTM1 allele gene locus is normally found in all human beings. When this is not expressed there is an increased risk of developing a malignancy of the upper(More)
Molecular dynamics studies were performed on eight different crystal structure complexes of protein tyrosine phosphatase 1B (PTP1B) to study energy components and interactions important for the binding of substrates/inhibitors. Calculation of the binding free energy and the different components was accomplished using molecular mechanics--Poisson-Boltzmann(More)
Protein kinase C (PKC) has been the center of many cell signaling pathways. PKC isoforms, specifically PKC-β II is linked to both diabetic complications as well as in promotion of angiogenesis and regulation of cancers. PKC-β II activates the PKB/Akt pathway. Enzastaurin, a selective PKC-β II inhibitor has been found to inhibit PKB/Akt by suppressing the(More)
Human leukocyte antigen-related (PTP-LAR) is a receptor-like transmembrane phosphatase and a potential target for diabetes, obesity and cancer. In the present study, a sequence of in silico strategies (pharmacophore mapping, a 3D database searching, SADMET screening, and docking and toxicity studies) was performed to identify eight novel nontoxic PTP-LAR(More)
The design of biological active compounds from the apoenzyme is still a challenging task. Herein a simple yet efficient technique is reported to generate a receptor based pharmacophore solely using a ligand-free protein crystal structure. Human leukocyte antigen-related phosphatase (PTP-LAR) is an apoenzyme and a receptor like transmembrane phosphatase that(More)
Intelligent Patent Analysis Tool (IPAT) is an online data retrieval tool, operated based on text mining algorithm to extract specific patent information in a predetermined pattern into an Excel sheet. The software is designed and developed to retrieve and analyze technology information from multiple patent documents and generate various patent landscape(More)
Laboratory dialysis, one of the most widely used techniques in biological research is truly a ' gateway technology' . The analogy is to that of a ' gate' of a building through which everybody has to pass, even though they may wish to go to different departments. Similarly, researchers may be working in altogether different areas but all may need to use(More)
