Dysregulation of noncoding RNA in chordoma; implications in identifying potential targets for novel therapeutic approaches.

Chordoma is a rare form of bone cancer develops in the spinal cord and skull. Instead of conventional (radio/chemotherapies) and targeted therapies, the disease is associated with high rate of recurrence and poor patient survival. Thus, for better disease management, the molecular pathogenesis of chordoma should be studied in detail to identify dysregulated biomolecules that can be targeted by novel therapeutics.

Differential operation of MLH1/MSH2 and FANCD2 crosstalk in chemotolerant bladder carcinoma: a clinical and therapeutic intervening study.

We aimed to understand the crosstalk between mismatch repair (MMR) and FA-BRCA pathway in primary bladder carcinoma (BlCa) samples as well as in chemotolerant cell line. We analysed the genetic alterations of MLH1 and MSH2 (MMR-related genes) and after that we correlated it with the nuclear translocation of FANCD2 protein. Next, we evaluated this crosstalk in T24 BlCa cell line in response to doxorubicin treatment.

Differential Microbial Signature Associated With Benign Prostatic Hyperplasia and Prostate Cancer.

Apart from other risk factors, chronic inflammation is also associated with the onset of Prostate Cancer (PCa), wherein pathogen infection and tissue microbiome dysbiosis are known to play a major role in both inflammatory response and cancer development. However, except for a few studies, the link between microbes and PCa remained poorly understood. To explore the potential microbiome signature associated with PCa in Indian patients, we investigated differential compositions of commensal bacteria among patients with benign prostatic hyperplasia (BPH) and PCa using 16S rRNA amplicon sequencing followed by qPCR analyses using two distinct primer sets.

Arsenic level in bladder tumor of patients from an exposed population: association with progression and prognosis.

To elucidate the impact of arsenic on progression and prognosis of bladder cancer. Total arsenic in 145 tumors (80 non-muscle-invasive [NMIBC] and 65 muscle-invasive bladder cancer [MIBC]) was measured and associated with Ki67 expression, tumor-clinicopathological parameters and patient outcome. Tumor arsenic concentration was higher in exposed than unexposed patients (256 μg/kg vs 77 μg/kg; p < 0.

Divergent molecular profile of PIK3CA gene in arsenic-associated bladder carcinoma.
