YAP (yes-associated protein) is a transducer protein involved in the progression of various cancer types and is reported to stimulate endometrial cancer progression via IL-6 and IL-11 elevation in a study by Wang et al. [48] YAP is upregulated in endometrial cancer cell lines and tissues more than in endometrial stromal cells or benign tissue and involved in endometrial cancer progression via IL-6 and IL-11 activation. The gene discussed is IL11; the disease is cancer.
