MAM Domain Containing 2 (MAMDC2) Affects Invasion and Metastasis of Human Gastric Cancer.
Background: Gastric cancer (GC) is the fifth most prevalent cancer worldwide and the fourth leading cause of cancer-related mortality. MAM Domain Containing 2 (MAMDC2) has been involved in many cancers. However, the impact of MAMDC2 on gastric cancer was unclear. This study aimed to investigate the role and mechanism of MAMDC2 in gastric cancer.
Methods: Differential genes in gastric cancer are analyzed by GEO, TCGA, MSigDB database, R-packet limma, and Wilcoxon test. Survival analysis is performed through the R package survival. Construct a PPI network through the STRING database. Enrichment analysis is performed by Metascape. The infiltration level of gastric cancer immune cells is calculated by CIBERSORT. In addition, the expression of MAMDC2 was analyzed by immunohistochemistry and quantitative real-time polymerase chain reaction (RT-qPCR). siMAMDC2 was used to knock down the specific gene. Cell counting kit-8 (CCK-8) assay, colony formation assay, and cell migration were applied to evaluate the function of MAMDC2 in gastric cancer cells.
Results: In the present study, we revealed a significant upregulation of MAMDC2 in gastric cancer tissues and cells. Knocking down MAMDC2 inhibited the proliferation and migration of gastric cancer cells, while overexpression of MAMDC2 produced the opposite results. Furthermore, MAMDC2 may be an independent factor in poor prognosis in gastric cancer patients.
Conclusion: These results illustrated that MAMDC2 promoted the proliferation and migration of gastric cancer cells. The newly identified MAMDC2 provides novel insight into the pathogenesis of gastric cancer.
期刊介绍：
OncoTargets and Therapy is an international, peer-reviewed journal focusing on molecular aspects of cancer research, that is, the molecular diagnosis of and targeted molecular or precision therapy for all types of cancer.
The journal is characterized by the rapid reporting of high-quality original research, basic science, reviews and evaluations, expert opinion and commentary that shed novel insight on a cancer or cancer subtype.
Specific topics covered by the journal include:
-Novel therapeutic targets and innovative agents
-Novel therapeutic regimens for improved benefit and/or decreased side effects
-Early stage clinical trials
Further considerations when submitting to OncoTargets and Therapy:
-Studies containing in vivo animal model data will be considered favorably.
-Tissue microarray analyses will not be considered except in cases where they are supported by comprehensive biological studies involving multiple cell lines.
-Biomarker association studies will be considered only when validated by comprehensive in vitro data and analysis of human tissue samples.
-Studies utilizing publicly available data (e.g. GWAS/TCGA/GEO etc.) should add to the body of knowledge about a specific disease or relevant phenotype and must be validated using the authors’ own data through replication in an independent sample set and functional follow-up.
-Bioinformatics studies must be validated using the authors’ own data through replication in an independent sample set and functional follow-up.
-Single nucleotide polymorphism (SNP) studies will not be considered.
