A molecular dynamics and docking study to screen anti-cancer compounds targeting mutated p53.

The p53 gene is mutated in greater than 50% of several human cancers including bladder urothelial carcinoma, lung adenocarcinoma, colorectal carcinoma, and oral cancer. Mutations in the p53 gene occur predominantly in the DNA-binding domain causing loss of function and accumulation of dysfunctional p53 protein in tumors by hetero-oligomerization with the wild type p53. Thus an in silico approach for the rational design of potent, pharmacologically active small drug-like compounds targeting mutated p53 was undertaken.

MicroRNAs in oral cancer: Biomarkers with clinical potential.

Oral cancer is the sixteenth most common cancer globally, with a relatively poor five-year survival rate of 50%. Thus it is imperative to understand the biology of oral cancer and examine alternative prognostic and therapeutic targets for oral cancer. MicroRNAs (miRNAs) are small non-coding RNAs mediating gene expression at the post-transcriptional level through mRNA degradation or translational repression.

Primary hyperparathyroidism as first manifestation in multiple endocrine neoplasia type 2A: an international multicenter study.

Objective: Multiple endocrine neoplasia type 2A (MEN 2A) is a rare syndrome caused by RET germline mutations and has been associated with primary hyperparathyroidism (PHPT) in up to 30% of cases. Recommendations on RET screening in patients with apparently sporadic PHPT are unclear. We aimed to estimate the prevalence of cases presenting with PHPT as first manifestation among MEN 2A index cases and to characterize the former cases.
