BackgroundSNRPC is cloned on human chromosome 6p21.31, which encodes a special protein component of U1 snRNP granules. Although SNRPC played an important role in the pre-mRNA splicing starting and adjustment, but in the tumor biological function is still unknown.MethodThrough the pan-cancer analysis of SNRPC, and our data sets, phosphorylation and functional network analysis based on TCGA (Cancer Genome Map) and GEO (Integrated Gene Expression Database), also from the western blot, qRT-PCR and CCK-8, cloning-forming experiment, scratch experiment to prove SNRPC biological function.ResultsSNRPC is related to the regulation of RNA, shear, and protease signals and has an important effect on ovarian cancer prognosis. Through a series of biological information data mining and basic experiments, we found that SNRPC plays an important role in the proliferation and migration of ovarian cancer. SNRPC expression is positively correlated with the immersion of CD4+T cells, macrophages, and neutrophils (p< 0.05), as obtained through the TIMER database (Tumor Immunological Assessment Resources) database. ConclusionOur pan-cancer research provides SNRPC in different tumors, especially the relatively comprehensive understanding of the carcinogenic potential of ovarian cancer.
