AI Article Synopsis
- Glypican 2 (GPC2) is found to be overexpressed in colorectal cancer, and its role in tumor cell proliferation and survival is investigated in this study.
- The research utilizes tissue samples, various laboratory techniques (like qRT-PCR and western blot), and animal models to confirm that knocking down GPC2 inhibits cancer cell growth both in vitro and in vivo.
- The findings suggest that GPC2 could serve as a potential oncogenic marker, offering insights for diagnosis and prognosis in colorectal cancer patients.
Article Abstract
Background And Study Aims: Glypican 2 (GPC2) is a member of the glypican gene family and is expressed in multiple kinds of cancer. However, the function and mechanism of GPC2 in colorectal cancer remains unclear. In this study, we aimed to identify the role of GPC2 on tumor cell proliferation and survival in colorectal cancer.
Patients And Methods: Ten pairs of colon cancer and matched normal colon tissues were collected in this research. GEPIA was used to analysis the GPC2 gene expression profile in TGCA data base. RT-qPCR and western blot assay were performed to determine the mRNA and protein expressions. CCK-8, Flow cytometry and colon formation assay were applied to evaluate cell viability. IHC staining was performed to evaluate the protein expression in tissues. The function of GPC2 in vivo was verified by an animal model of colon cancer.
Results: Through the bioinformatics analysis and qRT-PCR validation, we found that GPC2 was upregulated in the colon cancer tissues and cells. GPC2 knockdown suppressed cell proliferation in vitro and in vivo was confirmed by the results of CCK-8, colony formation assays, and tumor xenograft models. Moreover, by the analysis of flow cytometry assay and gain-or-loss function experiments, we discovered that CEP164 was highly associated with the expression state of GPC2, and mediated G2/M-phase arrest in GPC2-downregulated tumor cells.
Conclusion: GPC2 might be a novel oncogenic gene in colorectal cancer, suggesting that it could be a considerable marker for the diagnosis and prognosis of colorectal cancer.
