Cancer&Entry Information

Cancer Name	gastric cancer
ICD-0-3	C16
Methods	qPCR, Western blot, etc.
Sample	GC tissues, normal human gastric epithelial cell line GSE-1 and human gastric cancer cell lines SGC-7901 and BGC-823
Expression Pattern	up-regulated
Function Description	LncRNA PCGEM1 was overexpressed in GC cells and tissues, and was induced by hypoxia in GC cells. Additional experiments confirmed that the knockdown of PCGEM1 significantly repressed the invasion and metastasis of GC cells. SNAI1, a key transcription factor of EMT, was regulated by PCGEM1. Overexpression of SNAI1 rescued the inhibition of PCGEM1-knockdown during the invasion and metastasis of GC cells. In addition, PCGEM1 and SNAI1 jointly affected the biomarkers of EMT. CONCLUSION: Our findings indicated that PCGEM1 is a hypoxia-responsive lncRNA, and contributes to the invasion and metastasis of GC. The potential mechanism is attributed to the regulation of EMT by PCGEM1 and its influence on the expression of SNAI1.
