p53 is the most studied tumor suppressor and its overexpression may or may not cause cell death depending upon the genetic background of the cells. p53 is degraded by human papillomavirus (HPV) E6 protein in cervical carcinoma. Several stress activated kinases are known to phosphorylate p53 and, among them cyclin dependent kinase 5 (Cdk5) is one of the(More)
The tumor-suppressor p53 is a multifunctional protein mainly responsible for maintaining genomic integrity. p53 induces its tumor-suppressor activity by either causing cell-cycle arrest (G(1)/S or G(2)/M) or inducing cells to undergo apoptosis. This function of wild-type p53 as "guardian of the genome" is presumably achieved by forming molecular complexes(More)
Due to substantial technical improvements, clinical application of heat as a co-adjuvant in cancer treatment is acquiring new interest. The effect of hyperthermia on hepatoma cell lines Hep3B (p53 defective) and HepG2 (p53 wild type) when investigated led to an interesting observation that Hep3B cells are more susceptible to heat stress than HepG2 cells. In(More)
Hepatocellular carcinoma (HCC) is a primary malignancy of the liver and is a major cause of cancer related deaths worldwide. Only 10 to 20% of HCC can be surgically excised. Therefore, chemotherapeutic intervention and treatment is essential for achieving favorable prognosis. However, therapeutic outcome of chemotherapy is generally poor owing to inherent(More)
The in vivo hypoglycaemic activity of a dialysed fenugreek seed extract (FSE) was studied in alloxan (AXN)-induced diabetic mice and found to be comparable to that of insulin (1.5 U kg(-1)). FSE also improved intraperitoneal glucose tolerance in normal mice. The mechanism by which FSE attenuated hyperglycaemia was investigated in vitro. FSE stimulated(More)
In general, the activation of extracellular recognition kinase (ERK) cascade is implicated in exerting tumorigenic effects. Conversely, recent studies suggest that ERK activation may also have role in DNA-damage induced apoptosis [Wang, X., Martindale, J.L. and Holbrook, N.J. (2000) Requirement for ERK activation in cisplatin-induced apoptosis. J. Biol.(More)
Insulin-stimulated translocation of glucose transporter 4 (GLUT4) to cell membrane leading to glucose uptake is the rate-limiting step in diabetes. It is also a defined target of antidiabetic drug research. Existing GLUT4 translocation assays are based on time-consuming immunoassays and are hampered by assay variability and low sensitivity. We describe a(More)
Fluconazole based novel mimics containing 1,2,3-triazole were designed and synthesized as antifungal agents. Their antifungal activities were evaluated in vitro by measuring the minimal inhibitory concentrations (MICs). Compounds 12, 15, and 16 were found to be more potent against Candida fungal pathogens than control drugs fluconazole and amphotericin B.(More)
Fenugreek (Trigonella foenum-graecum) seeds, used as a condiment, are documented for health benefits including amelioration of abnormalities in lipid homeostasis due to its hypolipidemic properties. However, molecular mechanisms underlying the hypolipidemic effect of fenugreek seeds remain obscure. In this study, hypolipidemic effect of a novel thermostable(More)
There is constant increase in number of diabetic cases thereby giving it status of a serious epidemic. Diabetes increases the risk of occurrence of several cancers including breast cancer and may also have a serious impact on the outcome of cancer treatment. In the present study we investigated effect of hyperglycemia on cytotoxic efficacy of carboplatin(More)
