Methods A total of 209 diabetic patients without any antihyperglycemic history were recruited and treated with repaglinide or rosiglitazone randomly for 48 weeks （104 and 105 patients, respectively）. Anthropometric measurements and clinical laboratory tests were carried out before and after the treatment. An non-synonymous variant rs13266634 was genotyped by matrix-assisted laser desorption ionization-time of flight mass spectroscopy. Results Ninety-one patients in repaglinide group and ninety-three patients in rosiglitazone group completed the study. 6 value of homeostasis model assessment of beta cell function （HOMA-B） and 6 value of fasting proinsulin levels were statistically significant between three genotype groups （P=0.0149 and 0.0246, respectively） after rosiglitazone treatment. However, no genotype association was observed in the repaglinide or rosiglitazone group with other parameters. Conclusion The SLC3OA8 variant was associated with the efficacy of insulin sensitizer monotherapy on insulin secretion in patients with newly diagnosed type 2 diabetes mellitus in Shanghai, China.展开更多
目的:研究印记基因SLC22A18(solute carrier family 22,member 18)在乳腺癌中的表达情况及其与乳腺癌侵袭能力的关系。方法:采用Transwell方法评估2种不同恶性程度的乳腺癌细胞株MDA-MB-231(恶性程度高)和MCF-7(恶性程度低)的侵袭转移...目的:研究印记基因SLC22A18(solute carrier family 22,member 18)在乳腺癌中的表达情况及其与乳腺癌侵袭能力的关系。方法:采用Transwell方法评估2种不同恶性程度的乳腺癌细胞株MDA-MB-231(恶性程度高)和MCF-7(恶性程度低)的侵袭转移能力。分别采用实时荧光定量逆转录聚合酶链反应(RT-PCR)和蛋白质印迹法检测SLC22A18的mRNA和蛋白在这2种乳腺癌细胞株中的表达情况。结果:MDA-MB-231细胞株恶性程度高,穿过膜的细胞多,侵袭能力强;MCF-7细胞株恶性程度低,穿过膜的细胞少,侵袭能力弱;SLC22A18在MCF-7中的mRNA和蛋白表达水平高于MDA-MB-231;差异有统计学意义(P<0.01)。结论:印记基因SLC22A18的表达与乳腺癌细胞的侵袭能力相关,该基因有望作为一个抑癌基因抑制乳腺癌的转移。展开更多
