Z. T. Wang, Wang, L. Y., Wang, L., Cheng, S., Fan, R., Zhou, J., and Zhong, J., Association between RAGE gene polymorphisms and ulcerative colitis susceptibility: a case-control study in a Chinese Han population, vol. 14, pp. 19242-19248, 2015.

Ulcerative colitis (UC) is an immune-related disease with genetic predisposition. The aim of this study was to investigate the association of three polymorphisms in the receptor for advanced glycation end-products (RAGE) gene with UC risk in a Chinese population. This case-control study involved 72 UC patients and 479 age- and gender-matched healthy controls. Genotyping was performed using the polymerase chain reaction-ligase detection reaction method. Data were analyzed using the Haplo.stats program.

Lack of association between Gly82Ser, 1704G/T and 2184A/G of RAGE gene polymorphisms and retinopathy susceptibility in Malaysian diabetic patients

Diabetic retinopathy is the most common diabetic eye disease, occurring in about 60% of type 2 diabetic patients. Other than known clinical risk factors, the influence of genes has been suggested as part of the development of diabetic retinopathy. We investigated the association of Gly82Ser, 1704G/T and 2184A/G polymorphisms in the RAGE gene with retinopathy in type 2 diabetic patients in Malaysia. Ninety-eight unrelated retinopathy patients and 185 unrelated healthy controls from all over Malaysia were recruited in this study.

T., and Picheth, G., The functional polymorphisms -429T>C and -374T>A of the RAGE gene promoter are not associated with gestational diabetes in Euro-Brazilians, vol. 9. pp. 1130-1135, 2010.

The receptor for advanced glycation end products (RAGE or AGER) is a multiligand member of the immunoglobulin superfamily. RAGE is expressed in several tissues, including human myometrium, chorionic villi and placenta. Advanced glycation end products are the best studied ligands of RAGE; they have pro-inflammatory actions in human gestational tissues, increasing oxidative stress and the release of cytokines and prostaglandins.

Semi-quantitative detection of gene expression using bisbenzimide dye

P. Kittimongkolsuk, Tencomnao, T., and Santiyanont, R., Semi-quantitative detection of gene expression using bisbenzimide dye, vol. 10. pp. 3747-3759, 2011.

An electrochemical biosensor, using a disposable electrochemical printed chip aggregation by the bisbenzimide dye (Hoechst 33258), was used for detecting the expression of β-actin and RAGE genes. Using linear sweep voltammetry, the expression of these two genes in HeLa and HepG2 cell lines was determined based on anodic peak current, and the results were compared with conventional agarose gel electrophoresis. Total cellular RNA was reverse transcribed to complementary DNA, and amplification by PCR was carried out.
