Extracellular Vesicles Obtained From Lung Adenocarcinoma Cells Cultured Under Intermittent Hypoxia Induce M2 Macrophage Polarization via miR-20a-5p Delivery.

These findings indicate that EVs obtained from lung adenocarcinoma cells cultured under IH deliver miR-20a-5p to promote M2 macrophage polarization by targeting PTEN.

Identification of APC Mutation as a Potential Predictor for Immunotherapy in Colorectal Cancer.

To date, anticancer immunotherapy has presented some clinical benefits to most of advanced mismatch repair deficient (dMMR)/microsatellite instability-high (MSI-H) colorectal cancer (CRC) patients. In addition to MSI status, we aimed to reveal the potential predictive value of adenomatous polyposis coli (APC) gene mutations in CRC patients. A total of 238 Chinese CRC patients was retrospectively identified and analyzed for clinical features and gene alternations in APC-mutant type (MT) and APC-wild-type (WT) groups.

Phosphatase and tensin homolog deleted on chromosome 10 degradation induced by NEDD4 promotes acquired erlotinib resistance in non-small-cell lung cancer.

Acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors, such as gefitinib and erlotinib, is a critical issue in the treatment of patients with epidermal growth factor receptor mutant-positive non-small-cell lung cancer. Recent evidence suggests that downregulation of gene of phosphatase and tensin homolog deleted on chromosome 10 plays an important role in acquired resistance to epidermal growth factor receptor-tyrosine kinase inhibitors in various types of cancers, including lung cancer. It was reported that the E3 ubiquitin ligase neural precursor cell expressed developmentally downregulated gene (NEDD4) (also known as NEDD4-1) negatively regulated phosphatase and tensin homolog deleted on chromosome 10 protein levels through poly-ubiquitination and proteolysis in carcinomas of the prostate, lung, and bladder.
