Homologous recombination repair gene mutations in Malaysian prostate cancer patients.

Genetic alterations in the homologous recombination repair (HRR) genes are associated with an increased risk of prostate cancer development, and patients harboring these mutations can benefit from targeted therapy. The main aim of this study is to identify genetic alterations in HRR genes as a potential target for targeted treatment. In this study, targeted next generation sequencing (NGS) is used to analyze mutations in the protein-coding regions of the 27 genes involved in HRR and mutations in hotspots of 5 cancer-associated genes in four FFPE samples and three blood samples from prostate cancer patients.

Classical and alternative receptors for SARS-CoV-2 therapeutic strategy.

Understanding the molecules that are essential for severe acute respiratory syndrome coronavirus-2 (SARS-CoV-2) entry can provide insights into viral infection and dissemination. Recently, it has been identified from several studies that angiotensin-converting enzyme 2 receptor and transmembrane serine protease 2 are the main entry molecules for the SARS-CoV-2, which produced the pandemic of Covid-19. However, additional evidence showed several other viral receptors and cellular proteases that are also important in facilitating viral entry and transmission in the target cells.

Epidermal growth factor receptor () gene alteration and protein overexpression in Malaysian triple-negative breast cancer (TNBC) cohort.

Background: Epidermal growth factor receptor (EGFR) is a member of the ErbB family of tyrosine kinase receptor proteins that plays important roles in tumour cell survival and proliferation. EGFR has been reported to be overexpressed in up to 78% of triple-negative breast cancer (TNBC) cases suggesting it as a potential therapeutic target. The clinical trials of anti-EGFR agents in breast cancer showed low response rates.
