SNHG9 and breast carcinoma: Moreover, a study conducted in 2021 showed that the phosphatidic acid-binding lncRNA small nucleolar RNA host gene 9 (SNHG9) facilitates LLPS of LATS1—one of the key kinases of the Hippo pathway—to promote oncogenic YAP signaling.246 Clinically, SNHG9 expression was positively correlated with YAP and Ki-67 expression and breast cancer progression.246 The role played by RNA in tumorigenesis has been extensively explored by researchers, and we believe that LLPS is an important complement in the causal relationship between multiple RNAs and tumorigenesis.
