Detecting the Expression of ST3GalⅤ in Human Hepatic Carcinoma Cell Lines by Sialyltransferase DNA Microarray / 沈阳医学院学报

Objective: To investigate the differential expression of ST3GalⅤ in human hepatic carcinoma cell lines, HepG?2 and SMMC?7721 and normal hepatic cell line, L?02 by sialyltransferase DNA microarray. Methods: Expression of ST3Gal family was measured with DNA microarray. Western blot was used to verify DNA microarrays data. Result:ST3GalⅤ downregulated in HepG?2 and SMMC?7721 cell lines, compared with control cell line. Conclusion: The downregulation of ST3GalⅤ in HepG?2 and SMMC?7721 cell lines may result in the reduction of GD1a and influence the hepatocyte proliferations.
