BACKGROUND The purpose of this study was to explore the combined effect of melatonin receptor type 1A (MTNR1A) gene polymorphisms and exposure to environmental carcinogens on the susceptibility and clinicopathological characteristics of oral cancer. METHODOLOGY AND PRINCIPAL FINDINGS Three polymorphisms of the MTNR1A gene from 618 patients with oral cancer and 560 non-cancer controls were ana...

and Implications Human and sheep Melatonin receptor 1a (MTNR1A) gene information was used to clone a portion of the coding region of this gene in pigs, and to identify polymorphisms of the gene for its assignment to both the genetic linkage and physical maps. MTNR1A maps to pig chromosome 17, establishing a new region of conserved synteny between this chromosome and human chromosome 4. Furtherm...

Background/Aims: Melatonin receptor 1A (MTNR1A) gene is a regulator of circadian rhythms and reproductive processes. The MTNR1A gene is also a potential candidate gene of polycystic ovary syndrome (PCOS). The aim of the present study was to determine whether or not the MTNR1A gene polymorphism is associated with a predisposition to PCOS. Methods: The single nucleotide polymorphism (SNP) rs21198...

The response to melatonin expression is one way that circadian rhythms of many biological processes are regulated. To evaluate the relationship between the melatonin receptor 1A (MTNR1A) gene and reproductive performance, records were compared in Dorset and 3/4-Dorset x 1/4-East Friesian ewes expressing different genotypes at the MTNR1A gene in the Cornell University sheep flock. There were 116...

the ovine melatonin receptor 1a (mtnr1a) and aromatase (cyp19) genes were structurally characterized and the association between their variants and reproductive and growth traits was studied in kurdi sheep at kurdi sheep breeding station located in shirvan, iran. the genomic dna was extracted by guanidine thiocyanate-silica gel method. polymerase chain reaction was carried out to amplify 824 bp...

Melatonin counteracts tumor occurrence and tumor cell progression in several cancer types in vitro and in vivo. It acts predominantly through its melatonin receptor type 1A (MTNR1A), and genetic variations of MTNR1A affect the susceptibility several diseases and cancer. The purpose of this study was to explore the effect of MTNR1A gene polymorphisms on the susceptibility to and clinicopathologi...

Hepatocellular carcinoma (HCC) is a prevalent primary neoplasm of the liver, whose heterogeneous global incidence suggests the likely impact of genetic variations among individuals on the susceptibility to this disease. Increasing evidence indicates that melatonin exhibits oncostatic properties in many cancer types at least in part mediated by its membrane-bound receptors, melatonin receptor 1A...

The aim of the present work was to explore and characterize the different polymorphic variants of exon II region of MTNR1A gene in 31Corriedale sheep of Kashmir. Genomic DNA was extracted and subjected to PCR for the amplification of the main part of exon II of the ovine MTNR1A gene. PCR products were subjected to restriction enzyme (RE) digestion by MnlI restriction enzyme and depending upon n...
