A few articles report the molecules that regulate CTDSP1: USP29, one of the deubiquitinases (DUBs) enhances the interaction of Snail and CTDSP1, inducing Snail dephosphorylation and deubiquitination, and preventing Snail degradation in gastric cancer cells (37); 27-hydroxycholesterol (27-HC), the most abundant metabolite of cholesterol, inhibits PP2A and CTDSP1 transcription and then blocks c-Myc Ser62 dephosphorylation in breast cancer cells (38); miR-124 inhibits neuroglioma evolution via down-regulating CTDSP1(39). This evidence concerns the gene USP29 and gastric cancer.
