A recent report from Ain Shams University in Cairo, Egypt, discusses the challenges of castrate-resistant prostate cancer (CRPC) and the lack of a cure for this condition. The researchers aimed to investigate the expression of mismatch repair genes (MMR) and programmed death ligand-1 (PDL-1) in prostatic acinar adenocarcinoma cases to explore the potential use of immune checkpoint inhibitor drugs as a new therapeutic option. The study included 166 cases of prostatic acinar adenocarcinoma, and immunohistochemical staining was performed to assess the expression of MMR genes and PDL-1. The results showed that most cases had retained nuclear stain for all MMR genes, with only a few cases showing loss of expression. PDL-1 expression was observed in a small number of cases. The researchers concluded that immune checkpoint inhibitors may have limited value in CRPC, but further investigation is needed for cases showing loss of MMR proteins. [Extracted from the article]

A recent study conducted by researchers at the University of Patras in Greece has found that the protein Ras suppressor-1 (RSU1) plays a significant role in lung adenocarcinoma (LUADC), a type of lung cancer. The study found that RSU1 protein expression is downregulated in LUADC tissue samples and serves as a prognostic indicator. Depletion of RSU1 in lung cancer cells promotes cell growth, motility, and epithelial to mesenchymal transition (EMT). The study suggests that RSU1 acts as a tumor suppressor in LUADC. This research has been peer-reviewed and provides valuable insights into the understanding and treatment of lung cancer. [Extracted from the article]

Researchers from the University of Nebraska Medical Center have conducted a study on gemcitabine resistance in pancreatic ductal adenocarcinoma (PDAC). They focused on the role of trefoil factor 1 (TFF1) in gemcitabine resistance and found that TFF1 expression was inversely correlated with sensitivity to gemcitabine treatment. The study also revealed that TFF1 contributes to gemcitabine resistance by enhancing stemness, increasing migration ability of cancer cells, and inducing anti-apoptotic genes. Furthermore, the researchers identified the chemokine receptor CXCR4 as a possible receptor involved in TFF1-mediated gemcitabine resistance. Overall, this study highlights the contribution of the TFF1-CXCR4 axis in imparting gemcitabine resistance properties to PDAC cells. [Extracted from the article]

A preprint abstract from biorxiv.org discusses the involvement of cholinesterases in the immune landscape of lung adenocarcinoma (LUAD) and their prognostic values. The study collected cholinergic-related genes and examined their expression in LUAD samples and normal tissues, identifying 37 differentially expressed genes.
