Dengue, the most rapidly spreading flavivirus, threatens to affect almost half of the human global population. We previously showed that dengue-2 protects canine kidney cells (MDCK) from cytotoxic chemicals. We showed, independently, that cell protection, as well as viral replication and maturation, are positively regulated by PI3K-dependent autophagy. However, we had not identified the specific pathway that induces autophagy in infected cells. The current study explores the role of a specific branch of the endoplasmic reticulum (ER) stress-mediated Unfolded Protein Response (UPR), the PERK/eIF2α/ATF4 pathway in the induction of autophagy by …

Glioblastoma (GBM) is one of the most deadly forms of cancer with a mean 5-year survival rate of ≤5%. We have used the non-invasive strategy of long-term intranasal (IN) delivery of a glioblastoma-directed adduct of curcumin (CC), CC-CD68Ab, into the brain of murine GBM cell line GL261-implanted mice to study the therapeutic effect of CC on GBM remission. The treatment caused GBM tumor remission in 50% of GL261-implanted GBM mice. A similar rescue rate (60%) was also achieved through long-term intraperitoneal (i.p) infusion of a highly bioavailable phosphotidylcholine (PC)-encapsulated formulation of CC, Curcumin Phytosome Meriva (CCP), into the GL261-implanted GBM …

The poly (adenosine-diphosphate (ADP) ribose) polymerase (PARP) family of enzymes has been of interest to researchers and clinicians for over fifty years, especially the first member of the family, PARP1. This enzyme has become a target for cancer therapeutics due the reliance of highly proliferating cells on PARP1 for genomic maintenance. In the coming age of individualized medicine, however, highly specific therapeutic agents like PARP inhibitors are in need of similarly highly specific companion diagnostic agents. These kind of agents have been made possible with the quickly progressing field of molecular imaging. Specifically, positron emission tomography (PET) has enabled the …

Microrna 1207-3p In Prostate Cancer, Dibash Das
Dissertations, Theses, and Capstone Projects
Prostate cancer (PCa) is the most commonly diagnosed male cancer and the second leading cause of cancer-related death for men in the United States. Understanding the molecular mechanisms involved in progression from the asymptomatic androgen-dependent PCa to the lethal castration resistant prostate cancer (CRPC) is a major challenge. MicroRNAs (miRNAs), are known to be dysregulated in PCa. MicroRNA-1207-3p (miR-1207-3p) is encoded by the non-protein coding gene locus PVT1 on the 8q24 human chromosomal region, an established PCa susceptibility locus. However, the role of miR-1207-3p in PCa is unclear. We have discovered that miR-1207-3p is significantly underexpressed in PCa cell lines …
