Influence of TLR4 and TLR9 polymorphisms and haplotypes on multiple hrHPV infections and HPV16 copy number in cervical cancer and cervicitis.

Genetic polymorphism in pathogen recognition receptors tends to influence infection, disease susceptibility, and progression. We analyzed the association of TLR4 and TLR9 gene polymorphisms with multiple hrHPV infections and HPV16 copy number in cervicitis and cervical cancer. A total of 440 cervical cancer, cervicitis, and healthy individuals were studied using PCR-based assays.

Association of TLR4 and TLR9 gene polymorphisms and haplotypes with cervicitis susceptibility.

Background: Cervicitis is one of the major health problems amongst women caused by infection of various pathogens including Chlamydia trachomatis (CT), Neisseria gonorrhoeae (NG), Trichomonas vaginalis (TV) as well as human papillomavirus (HPV), and persistent cervical inflammation is one of the etiologic agents of cervical cancer. Toll-like receptors (TLRs) play an important role in the recognition and subsequent elimination of these pathogens. Variations in the Toll-like receptor genes influence susceptibility to pathogens as well as disease progression independently.

Association of TLR4 and TLR9 polymorphisms and haplotypes with cervical cancer susceptibility.

Single nucleotide polymorphisms (SNPs) in TLR genes may serve as a crucial marker for early susceptibility of various cancers including cervical cancer. The present study was therefore designed to ascertain the role of TLR4 and TLR9 SNPs and haplotypes to hrHPV infection and cervical cancer susceptibility. The study included 110 cervical cancer biopsies and 141 cervical smears from age-matched healthy controls of Gujarati ethnicity of Western India.
