Increased expression of the MYH9 gene is frequently observed in respiratory neoplasms, including lung cancer (Xu et al., 2021; Tang et al., 2022), reproductive tumors such as ovarian cancer (Liu L. et al., 2019; Liu L. et al., 2023), prostate cancer (Gao et al., 2022), as well as digestive system tumors like hepatocellular carcinoma (HCC) (Zhang F. et al., 2021; Hou et al., 2022a; Zhao R. et al., 2022), colorectal cancer (CRC) (Song M. et al., 2022) and esophageal cancer (EC) (Kai et al., 2022; Li Q. et al., 2023).
