MTOR and nonpapillary renal cell carcinoma: LncRNA PANDAR (Promoter of CDKN1 antisense DNA damage activated RNA) induces in p53-dependent mode interacts with the transcription factor NF-YA to repress the expression of pro-apoptotic genes, such as promoting the expression of Bcl-2 and McL-1, and down-regulating the expression of Bax, thereby inhibiting the PI3K/Akt/mTOR pathway leading to the proliferation and invasion of ccRCC cells 65.
