Ketorolac modulates Rac-1/HIF-1α/DDX3/β-catenin signalling via a tumor suppressor prostate apoptosis response-4 (Par-4) in renal cell carcinoma.

Renal cell carcinoma (RCC) is the most difficult-to-treat form of kidney cancer with a median 5-year survival of 10% under metastatic setting. In RCC, although cytoreductive nephrectomy is common, approximately 20-30% of patients will develop recurrent cancer after surgery, which highlights the need for an effective therapy. Rho-GTPases viz, Rac-1 and Cdc42 are the central regulators of cancer cell migration and invasion and thus metastasis in multiple cancer types.

Prostate Apoptosis Response-4 (Par-4): A Novel Target in Pyronaridine-Induced Apoptosis in Glioblastoma (GBM) Cells.

Glioblastoma (GBM) is an aggressive form of brain tumor with a median survival of approximately 12 months. With no new drugs in the last few decades and limited success in clinics for known therapies, drug repurposing is an attractive choice for its treatment. Here, we examined the efficacy of pyronaridine (PYR), an anti-malarial drug in GBM cells.

Association of AMH and AMHR2 gene polymorphisms with ovarian response and pregnancy outcomes in Indian women.

Purpose: To evaluate the association of single-nucleotide polymorphisms (SNPs) in the anti-Müllerian hormone (AMH) and AMH type II receptor (AMHR2) genes with ovarian response and clinical pregnancy outcomes in women undergoing controlled ovarian hyperstimulation.

Methods: In this prospective study, we genotyped AMH polymorphisms (c. -649 T > C, c.

Risk association of BST2 gene variants with disease progression in HIV-1 infected Indian cohort.

Bone marrow stromal cell antigen 2 (BST2) is an interferon induced host restriction factor for HIV-1 that blocks the release of nascent virions from infected T cells. We aimed to characterize BST2 gene variants in HIV-1 positive individuals in Indian cohort and study the association of these variants with disease progression in long term non progressors (LTNPs) and progressors. Archived samples of 32 LTNPs, 17 progressors, and 78 controls were screened for BST2 gene polymorphisms using Sanger's sequencing method.

Functional characterization of two naturally occurring mutations VG and TN in the follicle stimulating hormone receptor.

Naturally occurring mutations in follicle stimulating hormone receptor (FSHR) affect the receptor function. Here, we characterized two such previously reported mutations, VG and TN, in the extracellular domain and transmembrane helix 3, of FSHR, respectively. Functional studies with the VG mutant demonstrated an impairment in FSH binding and signaling.
