Zinc finger C3H1-type containing serves as a novel prognostic biomarker in human pan-cancer.

BACKGROUND:Zinc finger C3H1 domain-containing protein (ZFC3H1) is differentially expressed between primary tumor and the normal in most cancers. Additionally, a recent study has suggested that ZFC3H1 could serve as a novel marker for the prognosis of prostate adenocarcinoma (PRAD). However, the relationship between ZFC3H1 expression and the prognostic values in most tumors remains unclear. Our study is mainly for exploring the prognosis of ZFC3H1 in pan-cancer and for further discovering a potential therapeutics target. METHODS:Based on the clinical big data, we performed a pan-cancer analysis of ZFC3H1, including gene expression, survival prognosis, genetic alteration, protein phosphorylation, immune infiltration and enrichment analysis. In addition, Real-Time PCR and Western Blot were used to further confirm the role of ZFC3H1 in the colorectal cancer. RESULTS:We found that ZFC3H1 expression was connected with the prognosis of multiple malignant tumors. Furthermore, we also observed that ZFC3H1 was highly expressed in colorectal cancer through Real-Time PCR and Western Blot. The primary tumors presented higher phosphorylation level of the S655 site in lung adenocarcinoma, colon adenocarcinoma and uterine corpus endometrial carcinoma. ZFC3H1 expression was positively correlated with the immune infiltration of Cancer-associated fibroblasts (CAFs) in some tumors, such as liver hepatocellular carcinoma. And RNA surveillance pathways may be closely associated with the occurrence of tumors. CONCLUSIONS:Our study first reveals that ZFC3H1 could serve as a novel prognostic biomarker of pan-cancer, especially colorectal cancer.
