Gene RIF (54)

26519818 rs2119882 polymorphism was associated with polycystic ovary syndrome in Han Chinese. A significant difference in transmission of allele C of rs2119882 was found between obese and non-obese women with PCOS.
25822611 Sections from paraffin-embedded normal tissue from 42 individuals, representing the different parts of the GI tract (n=39) and pancreas (n=3) were studied with immunohistochemistry using antibodies for melatonin, MT1 and MT2 receptors and serotonin.
25806809 results support gene-environment interactions of MTNR1A polymorphisms with smoking and betel quid-chewing habits possibly altering oral-cancer susceptibility and metastasis
25514412 There were no significant differences between the expression of MT1 and histological type, staging, grading, presence of residual disease, or overall survival time.
24724723 this study provides a detailed delineation of the melatonin-mediated activation of ERK1/2 in HEK293 cells that are transfected with melatonin receptor MT1.
24157813 genetic polymorphisms rs2119882 in melatonin receptor 1A (MTNR1A) and rs10830963 in melatonin receptor 1B (MTNR1B) are associated with an increased risk of developing gestational diabetes mellitus and insulin resistance in Han Chinese women
24117008 Suggest that physiological regulation of the melatonin receptors may result from complex and subtle mechanisms, a small difference in affinity between the active and inactive states of the receptor, and spontaneous coupling to G-proteins.
23725077 MR-1A placental expression is elevated in all types of hypertensive syndromes in pregnancy
23333399 Genetic inactivation of both transgenic MT1 and MT2 receptors produces an increase of wakefulness, likely as a result of reduced NREMS due to the lack of MT2 transgene receptors, and reduced REMS induced by the lack of MT1 transgene receptors.
23250547 MT1 negative TNBC in all cases regardless of race showed a significantly higher hazard ratio for disease progression, shorter progression free survival, and disease-related death, and shorter OS.
