In Vitro And In Vivo Anti-Angiogenic Activities Of Milk Sphingolipids, Rishipal Rastrapal Bansode
In Vitro And In Vivo Anti-Angiogenic Activities Of Milk Sphingolipids, Rishipal Rastrapal Bansode
LSU Doctoral Dissertations
Anti-angiogenic therapies aimed at halting new blood vessel formation are now being extensively studied as inhibitors of excessive angiogenesis. Conversely, compounds with ability to stimulate angiogenesis are being considered as a therapeutic approach for insufficient angiogenesis. Food-borne bioactive compounds such as genistein, resveratrol, curcumin, the Bowman-Birk inhibitor, and catechins are being potentially established as good candidates for angioprevention. The aim of our study was to determine the anti-or pro-angiogenic activity of milk-based glycosphingolipids such as C6-ceramide (Cer), Sphingomyelin (SPM) and Glucosylceramide (GluCer), in vitro, using breast cancer (MCF-7), colon cancer (Caco-2) and prostate cancer (DU-145) cell-lines, on angiogenic factors such …
Identification Of The Rna Cis-Elements That Interact With Srp30a To Regulate The Alternative Splicing Of Caspase 9 Pre-Mrna, Prabhat Mukerjee
Identification Of The Rna Cis-Elements That Interact With Srp30a To Regulate The Alternative Splicing Of Caspase 9 Pre-Mrna, Prabhat Mukerjee
Theses and Dissertations
Studies have shown that the alternative splicing of caspase 9 and the phospho-status of SR proteins, a conserved family of splicing factors, are regulated by chemotherapy and de novo ceramide via the action of protein phosphatase-1 (PP1). Two RNA splice variants are derived from the caspase 9 gene, pro-apoptotic caspase 9a and anti-apoptotic caspase 9b, via alternative splicing by either the inclusion or exclusion of an exon 3, 4, 5, and 6 cassette. In this study, the link between SR proteins and the alternative splicing of caspase 9 was established. Sequence analysis of the exon 3, 4, 5, and 6 …
Tumor Response Tcf-4/Β-Catenin Regulatory Elements For Enhancing Cancer Gene Therapies, Saurabh Kumar Gupta
Tumor Response Tcf-4/Β-Catenin Regulatory Elements For Enhancing Cancer Gene Therapies, Saurabh Kumar Gupta
Theses and Dissertations in Biomedical Sciences
Mutations in the adenomatous polyposis coli gene are frequently associated with progression of colon carcinoma and most other types of epithelial carcinomas. This usually results in stabilization of β-catenin protein levels, followed by transactivation of Tcf-4/β-catenin responsive genes. The effectiveness of a Tcf-4/β-catenin transcriptional enhancer element in combination with a c-fos or carcinoembryonic antigen promoter was tested for its ability to act as a tumor specific regulator of gene expression in a panel of human tumor and normal cell lines. Luciferase reporter assays indicated enhanced activity of the Tcf-4/β-catenin transcriptional element only in tumor cell lines, with minimal activities in …
