A novel p16(INK4A) mutation associated with esophageal squamous cell carcinoma in a high risk population.

This study describes identification of p16(INK4A) sequence variants and their potential association with esophageal squamous cell carcinoma (ESCC) in a high risk population from Kashmir, India. We report a novel 7 base pair exon 2 deletion in 22 out of 106 (~20%) surgically resected tumor samples. The deletion beginning at the second base of codon 103, results in a frame shift causing premature termination of the protein at codon 142, with structural and functional consequences predicted by insilico analysis.

Functional cloning and predictive structural modeling of a novel esterase from Bacillus subtilis strain, RRL 1789.

We have recently reported the purification and characterization of a novel esterase from the Bacillus subtilis strain. In the present study we report the genomic DNA cloning and predictive structural modeling of this novel esterase. Tributyrin- and Rhodamine B-based functional screen of a Bacillus subtilis genomic library led to the identification of a potential lipolytic gene.
