Disease Class: Gastric cancer [ICD-11: 2B72.0]				[1]
Resistant Disease	Gastric cancer [ICD-11: 2B72.0]			Disease Info
Resistant Drug	Fluorouracil			Drug Info
Molecule Alteration	Expression		Up-regulation
Experimental Note	Revealed Based on the Cell Line Data
In Vitro Model	SGC-7901 cells	Gastric	Homo sapiens (Human)	CVCL_0520
	5-FU cells	Colon	Homo sapiens (Human)	CVCL_1846
Experiment for Molecule Alteration	RT-PCR
Experiment for Drug Resistance	MTT assay
Mechanism Description	The miRNA expression profiles between the parental and resistant gastric cancer cells were analyzed by Human miRNA OneArray? v3 and the results were confirmed by quantitative real-time RT-PCR. The expression of 9 miRNAs (miR-10b, -22, -31, -133b, -190, -501, -615, -501-5p and -615-5p) was upregulated while the expression of 18 additional miRNAs (miR-32, -197, -210, -766, -1229, -1238, -3131, -3149, -1224-3p, -3162-3p, -532, -877, -4701-5p, -5096, -4728-3p, -1273d, -486-3p and-4763-3p) was downregulated in the SGC-7901/5-Fu cell line compared with its parental cell line. The results indicate that miRNA expression correlates with MDR in gastric cancer and may serve as biomolecular targets for MDR elimination.
