The role of Tripartite motif containing 59 (TRIM59) in the proliferation and prognosis of intrahepatic cholangiocarcinoma

Tripartite motif containing 59 (TRIM59) is a crucial gene that is involved in the process of various types of cancer，including breast cancer, lung cancer, colorectal cancer,and so on. Its abnormal expression can affect tumor cell proliferation, metastasis, or apoptosis. In liver cancer, the incidence of intrahepatic cholangiocarcinoma (ICC) is increasing. However, However, it has not been clearly reported on TRIM59 affects the progress of intrahepatic cholangiocarcinoma cells.Firstly, we review the expression of TRIM59 in different cancers and the corresponding normal tissues，and the results preliminarily showed that TRIM59 may be abnormally expressed in many cancers. The author focuses on whether TRIM59 plays a crucial biological role in intrahepatic cholangiocarcinoma. Therefore, we have confirmed through online websites that TRIM59 is highly expressed in intrahepatic cholangiocarcinoma tissues. Furthermore we further found that TRIM59 can be used as an effective prognostic marker for the prognostic guidance of patient survival time. Next, we explore whether the expression level of TRIM59 in intrahepatic cholangiocarcinoma is related to proliferation through the CCK-8 and EDU assay in two ICC cell lines. To further explore how TRIM59 affected the molecular mechanism involved in intrahepatic cholangiocarcinoma cell growth, we found that STAT3 promotes TRIM59 transcription and TRIM59 can affect tumor progression by regulating the PI3K/AKT signaling pathway through luciferase reporter assay and Western blot experiments. In summary, we first found that TRIM59 has great research value in ICC through bioinformatic analysis, then its expression level is closely related to the prognosis through the analysis of clinicopathological indicators of patients with ICC, and the biological mechanism of TRIM59 in ICC provides precise research or therapeutic targets for future cancer treatment. The findings improve our understanding of the potential of TRIM59 in biological functions in ICC and may hold promise as markers for the diagnosis,treatment, and prognosis of ICC.
