RGS1 and cancer: RGS1 expression was significantly correlated to poor prognosis in seven cancers, including LIHC, adrenocortical carcinoma (ACC), pancreatic adenocarcinoma (PAAD), sarcoma (SARC), SKCM, STAD, and THYM (Figure 3D), suggesting that RGS1 was a potential prognostic factor in the survival of the above cancers.
