Zusammenfassung: | To study the differential expression and possible role of MLRQ subunit gene of nicotinamide adenine dinucleotide reduced (NADH) oxidoreductase in malignant tumors of digestive system.
Specimens of cancerous tissues and matched adjacent normal tissues resected during operation or biopsy: 38 pairs of specimens of esophageal carcinoma, 7 pairs of specimens of cardiac carcinoma, 14 pairs of specimens of gastric carcinoma, 11 pairs of specimens of colon carcinoma, and 7 pairs of specimens of liver carcinoma underwent PCR test and Northern hybridization to detect the differential expression of MLRQ subunit gene of NADH oxidoreductase.
(1) Overexpression of MLRQ subunit gene was found in 31 of the 38 pairs of specimens of esophageal carcinoma (81.6%), 4 of the 7 pairs of specimens of cardiac carcinoma (57.1%), 12 of the 14 pairs of specimens of gastric carcinoma (85.7%), 4 of the 7 pairs of specimens of colon carcinoma (65.6%), and 7 of the 11 pairs of specimens of liver cancer (57.1%). No significant difference amo |
