Glecirasib in KRAS-mutated nonsmall-cell lung cancer: a phase 2b trial.

Glecirasib (JAB-21822) is a new covalent oral KRAS-G12C inhibitor. This multicenter, single-arm phase 2b study assessed the efficacy and safety of glecirasib administered orally at 800 mg daily in patients with locally advanced or metastatic KRAS-mutated nonsmall-cell lung cancer. The primary endpoint was the objective response rate (ORR) assessed by an independent review committee (IRC).

EZH2 supports ovarian carcinoma cell invasion and/or metastasis via regulation of TGF-beta1 and is a predictor of outcome in ovarian carcinoma patients.

It was suggested that the enhancer of zeste homolog 2 (EZH2) gene is a putative candidate oncogene in several types of human cancer. The potential oncogenic role of EZH2 and its clinical/prognostic significance, however, in ovarian carcinoma are unclear. In this study, EZH2 expression was examined by immunohistochemistry (IHC) in cohorts of normal and tumorous ovarian tissues.

Decreased expression of PinX1 protein is correlated with tumor development and is a new independent poor prognostic factor in ovarian carcinoma.

Human interacting protein X1 (PinX1) has been identified as a critical telomerase inhibitor and proposed to be a putative tumor suppressor gene. Loss of PinX1 has been found in a large variety of malignancies, but the expression status in epithelial ovarian tumors has not been investigated. In this study, immunohistochemistry for PinX1 protein was performed on a tissue microarray (TMA) of epithelial ovarian tumors (informatively containing 25 cystadenomas, 29 borderline tumors, and 157 invasive carcinomas) and 12 normal ovaries.
