Abstract

Aims: We aim to explore the possibility and mechanism of SH3PXD2B as a reliable biomarker for gastric Cancer (GC).

Main methods: We used public databases to analyze the molecular characteristics and disease associations of SH3PXD2B, and KM database for prognostic analysis. The TCGA gastric Cancer dataset was used for single gene correlation, differential expression, functional enrichment and immunoinfiltration analysis. SH3PXD2B protein interaction network was constructed by the STRING database. And the GSCALite database was used to explore sensitive drugs and perform SH3PXD2B molecular docking. The impact of SH3PXD2B silencing and over-expression by lentivirus transduction on the proliferation and invasion of human GC HGC-27 and NUGC-3 cells was determined.

Key findings: The high expression of SH3PXD2B in gastric Cancer was related to the poor prognosis of patients. It may affect the progression of gastric Cancer by forming a regulatory network with FBN1, ADAM15 and Other molecules, and the mechanism may involve regulating the infiltration of Treg, TAM and Other immunosuppressive cells. The cytofunctional experiments verified that it significantly promoted the proliferation and migration of gastric Cancer cells. In addition, we found that some drugs were sensitive to the expression of SH3PXD2B such as sotrastaurin, BHG712 and sirolimus, and they had strong molecular combination of SH3PXD2B, which may provide guidance for the treatment of gastric Cancer.

Significance: Our study strongly suggests that SH3PXD2B is a carcinogenic molecule that can be used as a biomarker for GC detection, prognosis, treatment design, and follow-up.
