ABSTRACT
Proline and serine-rich coiled-coil 1 (PSRC1) has been reported to function as an oncogene in several cancers by regulating mitosis, while there are few reports on the role of PSRC1 in lower-grade glioma (LGG). Thus, this study collected 22 samples and 1126 samples from our institution and several databases, respectively, to explore the function of PSRC1 in LGG. First, the analysis of clinical characteristics showed that PSRC1 was always highly expressed in more malignant clinical characteristics of LGG, such as higher WHO grade, recurrence type, and IDH wild type. Second, the prognosis analysis revealed that the high expression of PSRC1 was an independent risk factor contributing to the shorter overall survival of LGG patients. Third, the analysis of DNA methylation showed that the expression of PSRC1 was associated with its 8 DNA methylation sites, overall negatively regulated by its DNA methylation level in LGG. Fourth, the analysis of immune correlation revealed that the expression of PSRC1 was positively correlated with the infiltration of 6 immune cells and the expression of 4 well-known immune checkpoints in LGG, respectively. Finally, co-expression analysis and KEGG analysis showed the 10 genes most related to PSRC1 and the signaling pathways involved by PSRC1 in LGG, respectively, such as MAPK signaling pathway and focal adhesion. In conclusion, this study identified the pathogenic role of PSRC1 in the pathological progression of LGG, expanding the molecular understanding of PSRC1, and provided a biomarker and potential immunotherapeutic target for the treatment of LGG.
