Increased expression of the NETO2 gene has been observed in proliferating infantile hemangiomas (Calicchio et al., 2009), hepatocellular (Villa et al., 2016) and nasopharyngeal carcinomas (He et al., 2019), as well as in renal (Snezhkina et al., 2018), lung (Oparina et al., 2012), colorectal (Hu et al., 2015; Fedorova et al., 2017), gastric (Liu et al., 2019), and pancreatic (Li et al., 2019) cancers. The gene discussed is NETO2; the disease is cancer.
