The impact of HER2 somatic mutations in colorectal carcinoma (CRC) has not been well studied and its relationship with microsatellite instability-high (MSI-H) is yet to be fully elucidated. From February 2017 to February 2020, the data of patients with CRC who underwent next-generation sequencing and had detailed record of clinicopathological information were investigated. HER2 alteration and its relationship with MSI-H were analyzed. Among 731 patients who underwent sequencing, 55 patients (7.5%) had HER2 alteration, including 29 (4.0%) with HER2 somatic mutations, 24 (3.3%) with HER2 gene amplification, and 2 patients (0.2%) with both HER2 mutations and amplification. R678Q was the most common mutated kinase domain, and no HER2 kinase domain in-frame insertions/deletions were found in HER2 mutated cases. MSI-H was found in 5.2% of our cohort and 36.8% of MSI-H patients had HER2 mutation. For HER2 mutated cases, 48.3% were MSI-H, whereas none of the HER2 amplification cases were MSI-H. MSI-H patients wch to explore the internal relationship between HER2 alteration and MSI-H is needed.Liver diseases are a major health issue in both men and women and cause significant mortality worldwide. The hepatoprotective effects of kirenol were evaluated in acetaminophen (APAP)-induced toxicity in HepG2 cells and ethanol (EtOH)- induced hepatotoxicity in rats. The cytotoxicity of kirenol (IC50 , 25 µM/ml) and APAP (20 µg/ml) with sylimarin (IC50 , 15 µg/ml) was observed in HepG2 cells by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay. Furthermore, reactive oxygen species formation, mitochondrial membrane potential, and oxidative stress markers such as thiobarbituric acid-reactive substance, suproxide dismutase, and catalase were assayed. Rats were administered a different dose (10, 20, and 30 mg/kg/day) for a period
