evaluation of long stress-induced non-coding transcripts 5 polymorphism in iranian patients with bladder cancer

Background: bladder cancer (bc) is the most commonly diagnosed genitourinary cancer in iran, presented in both men and women. bc is a multifactorial trait resulting from the complex interaction between several genes and environmental factors. long stressinduced noncoding transcript 5 (lsinct5), a member of the long noncoding rnas, is abundantly expressed in high proliferative cells, as well as the cells vulnerable to cellular stress in response to chemical carcinogens.this casecontrol study aimed to determine any association between lsinct5 rs2962586 polymorphism and bladder cancer.materials and methods: a group of 150 patients with bc were compared with 143 subjects as a control group. genotyping of the rs2962586 polymorphism was done using tetra primer amplification refractory mutation systempolymerase chain reaction (tarms pcr) method.results: genotype and allele distribution were not significantly different between the case and control groups. smoking was found to be the confounding risk factor for bladder cancer.conclusion: considering the result of our analyses, it seems that lsinct5 could not affect individual susceptibility to bc among iranian patients, however, it can be considered as a disease predictor among smokers.
