NEAT1 enhances the expression of PTRF by interacting with the PTRF/Cavin-1, thereby stabilizing its mRNA, and PTRF activates NF-κB signaling by inhibiting the expression of UBXN1, thereby upregulating the transcription of PD-L1 and promoting the immune escape of tumor cells 158. This evidence concerns the gene CAVIN1 and neoplasm.
