Western blot and RT-PCR were used to analyze the expression or mRNA level of CERS1 at different tissues or cell lines. Afterwards, the occurrence and development of hypophysoma in vivo and in vitro, respectively, was observed by using CERS1 overexpression by lentivirus. Finally, MK-2206 and LY294002 were applied to discuss whether the role of CERS1 was regulated by the PI3K/AKT signaling pathway. Results show that the CERS1 expression and mRNA level in tumor or AtT-20 cells were decreased. CERS1 over-expressed by lentivirus could inhibit hypophysoma development in vivo and in vitro by reducing tumor volume and weight, weakening tumor proliferation and invasion, and enhancing apoptosis. In addition, shCERS1 could reverse the process. The above results indicate that CERS1 is possibly able to enhance autophagy in hypophysoma through the PI3K/AKT signaling pathway.USP15 is a member of ubiquitin-specific proteases (USPs, the largest subfamily of deubiquitinases) and functions as a stabilize factor of target proteins in reversible ubiquitiantion progression. Dysregulated expression of USP15 has been observed in various cancers. However the expression profile and regulatory mechanism of USP15 in hepatocellular carcinoma (HCC) remains largely elusive. To exam the USP15 expression changes in the progression of HCC, we performed IHC analysis to test USP15 expression in a series of cancer-prone diseases including 2 normal liver tissues, 6 liver cirrhosis, 16 primary liver lesions and 15 metastases of hepatocellular carcinoma. The expressi
