Influence of polymorphisms on the phenotype of TLR1, TLR4 and TLR9 genes and their association with cervical cancer: Bioinformatics prediction analysis and a case-control study.

Susceptibility to cervical cancer has been associated with Toll-like receptors (TLRs), which is an important component of innate immunity. According to previous studies, polymorphisms in TLRs genes can affect immune response pathways and lead to the development of cervical cancer. The present study aims to evaluate the functionality of polymorphisms in TLR1, TLR4 and TLR9 genes and their associations with cervical cancer.

The Role of the IL-10 (-819C/T), TNFA (-308G/A) and ENOS (-786T/C) Polymorphisms of Impulsive and Aggressive Personality Traits in Cocaine/Crack Users.

Cytokines and nitric oxide have been associated with impulsive and aggressive personality traits. We conducted the first study that investigated the role of SNPs in cytokines and nitric oxide genes and the influence in the progression of aggressive and impulsive behavior in 107 of cocaine and crack users. In this case-control, IL-10 (-819C/T), TNFA (-308G/A) and ENOS (-786T/C) polymorphisms were determined by Real-Time PCR.

Polymorphisms in Toll-like receptors genes changes the host's immune response and is associated with cervical cancer.

Polymorphisms in Toll-like receptors (TLRs) genes have been associated with cervical cancer, but some inconsistencies were found in the results. The present study aimed to investigate the role of polymorphisms in the TLRs genes in cervical cancer, through meta-analysis and bioinformatics analysis. Searches were performed in PubMed, Science Direct, Scopus and Web of science online databases until November 2020.

and Polymorphisms Modulating the Outcome Related to Mental Disorders in Crack Addicted Users.

Background: Cocaine/crack use affects immune system molecules and development of mental disorders has been identified.

Objective: To investigate the relationship of polymorphisms in the (-308G/A), IL-10 (-819C/T) and (-786T/C) genes with mental disorders in cocaine and crack users.

Methods: A case-control study was carried out, which included 107 cocaine and crack users and 115 controls who never used healthy cocaine and crack.

Depression and anxiety symptoms correlate with diurnal preference, sleep habits, and Per3 VNTR polymorphism (rs57875989) in a non-clinical sample.

Background: Evidences suggest that alterations in circadian rhythms trigger the development of mental disorders. Eveningness, sleep behavior, and circadian genes polymorphisms have been associated with depression and anxiety symptomatology. However, the mechanism underlying these interactions is not well understood.

Association of Polymorphisms in Cytokine genes with susceptibility to Precancerous Lesions and Cervical Cancer: A systematic review with meta-analysis.

: This study investigated the relationship between single-nucleotide polymorphisms (SNPs) in cytokine genes and the susceptibility to Squamous Intraepithelial Lesions (SIL), cervical cancer and HPV infection through a systematic review with meta-analysis. To verify the effect of SNPs, we also analyzed the transcription factor binding affinity using bioinformatics tools.: Seven electronic databases (MEDLINE, Scielo, BIREME, PubMed, Scopus, Web of Science and Science Direct) were searched for case-control studies.

Melatonin receptor 1B -1193T>C polymorphism is associated with diurnal preference and sleep habits.

Background: Melatonin modulates the master circadian clock through the activation of G-protein-coupled receptors MT1 and MT2. It is presumed, therefore, that genetic variations in melatonin receptors can affect both sleep and circadian phase. We investigated whether the -1193T > C (rs4753426) polymorphism in the promoter of MT2 receptor gene (MTNR1B) is associated with diurnal preference and sleep habits.

Association of polymorphisms in serotonin and nitric oxide genes with clinical outcome of dengue in Brazilian northeast population.

Serotonin and nitric oxide seem to be involved in Dengue virus infection. The aim of this study was to investigate if SNPs in serotonin and nitric oxide are associated with dengue severity. A retrospective case-control study was conducted, with groups of dengue fever (DF; n = 78) and dengue hemorrhagic fever patients (DHF; n = 49).
