Polyribonucleotide phosphorylase is overexpressed in hepatocellular cancer, promoting epithelial phenotype maintenance and tumor progression.

Liver cancer, particularly hepatocellular carcinoma (HCC), is a major global health challenge, largely associated with cirrhosis caused by various factors. Prognosis is often guided by molecular and histological classifications. In this study, expression of Polyribonucleotide Phosphorylase (PNPT1) in HCC was investigated to better understand its role in tumor behavior and patient outcomes.

Enhancing Prostate Tumor Biobanking Reliability with Improved Sampling Technique and Histological Characterization.

Acquiring fresh and well-characterized tumor tissue samples is critical for conducting high-quality "omics" studies. However, it can be particularly challenging in the context of prostate cancer (PC) due to the unique nature of this organ and the high heterogeneity associated with this tumor. On the other hand, histopathologically characterizing samples before their storage without causing significant tissue alterations is also an intriguing challenge.
