BACKGROUND Oral cancer is a common cancer and a major health problem in the Indian subcontinent. At our laboratory Mcl-1, an anti-apoptotic member of the Bcl-2 family has been demonstrated to be overexpressed in oral cancers and to predict outcome in oral cancer patients treated with definitive radiotherapy. To study the role of Mcl-1 isoforms in radiation(More)
Expression of Bcl-2 family proteins in tumours can modulate apoptosis, influencing tumour behaviour and treatment. To investigate their role in oral tumourigenesis, nine Bcl-2 family transcripts were examined in three oral cell lines and 25 oral tumours, using ribonuclease protection assay. Since Mcl-1 mRNA was elevated in these samples, Mcl-1 splice(More)
The expression of inhibin, a 10.7 kD follicle-stimulating hormone (FSH)-suppressing prostatic peptide of 94 amino acids, was investigated in normal human endometrium, endometrial hyperplasia, and adenocarcinoma, employing the avidin-biotin immunoperoxidase technique. The antiserum used was raised in rabbits against prostatic inhibin isolated from human(More)
The inactivation of p53 tumour suppressor gene vis-á-vis point mutation, overexpression and degradation due to Human Papilloma virus (HPV) 16/18 infection, was examined in chewing tobacco-associated oral cancers and oral leukoplakias from India. The analysis of mutations was assessed by polymerase chain reaction (PCR) with single strand conformation(More)
BACKGROUND Limited data are available on the prevalence and prognostic significance of human papillomavirus (HPV) in squamous cell carcinoma of head and neck (SCCHN) in the Indian population. AIM The present study aimed to determine the prevalence of HPV and p16 in an Indian cohort of SCCHN and assess their correlation and influence of tobacco use on(More)
BACKGROUND Altered expression of Mcl-1, an anti-apoptotic member of the Bcl-2 family, has been linked to the progression and outcome of a variety of malignancies. We have previously reported the overexpression of Mcl-1 protein in human oral cancers. The present study aimed to evaluate the clinicopathological significance of the expression of three known(More)
The levels of immunoreactive prostatic inhibin-like peptide (PIP), having follicle-stimulating hormone suppressing properties, were estimated in the sera and urine samples of patients with benign prostatic hyperplasia (BPH) and prostatic carcinoma (PC) as compared to age-matched controls. Significantly elevated serum PIP levels in BPH (107.8 +/- 19 ng/ml)(More)
At our laboratory, we recently observed cell cycle and apoptosis-related proteins Myeloid Cell Leukemia-1 (Mcl-1) and Proliferating Cell Nuclear Antigen (PCNA) to be altered in oral tumours/cell lines. The present study aimed to evaluate the above proteins for predicting response and outcome in oral cancer patients treated with definitive radiotherapy.(More)
Deregulation of oncogenes and tumor suppressor genes involved in apoptosis has been associated with tumor development and progression. To investigate the involvement of apoptosis regulating proteins in oral cancer in Indian patients, primarily associated with chewing tobacco habits, immunohistochemical expression of bcl-2 and bax was examined in 63 oral(More)
Radiotherapy is an important treatment modality for oral cancer. However, development of radioresistance is a major hurdle in the efficacy of radiotherapy in oral cancer patients. Identifying predictors of radioresistance is a challenging task and has met with little success. The aim of the present study was to explore the differential spectral profiles of(More)
