Using the RT-PCR method for allele discrimination, we examined nine known SNPs in seven genes (GHR, IGFBP3, IGFR1, IRS1, FMN1, ANXA2, TaGLN) in ethnic Russians and in patients with prostate cancer (PC). For Russian population data on genotype distribution in studied SNPs was obtained. It was revealed that six of nine analyzed sites in examined locus were polymorphic. Distributions of alleles and genotypes frequency of polymorphic site 1388 T/C (Leu463Pro) in gene FMN1 (rs2306277) were distinguished between patients and control groups (delta = 0.019; chi2 = 7.884). In particular, correlation of OO genotype with increased risk of PC was observed (OR = 2.1591 95% CI 1.2055-3.8726). Moreover, the analysis of the polymorphic site 2911G/A (Glu917Arg) in gene IRS1 (rs1801278) revealed the accumulation of allele A in cancer group in comparison with control group (chi2 = 4.038; p = 0.044). Thus, the obtained data indicate the possibility of participation of polymorphism in genes FMN1 and IRS1 in formation of predisposition to PC.

Toll-like receptors (TLRs) are crucial components of innate immunity. A specific form of genetic variation in TLR genes may increase the chance of developing leukemia. The present investigation conducted a comprehensive meta-analysis to examine the correlation between three TLR polymorphisms, namely TLR2 (rs3804099), TLR4 (rs4986790), and TLR9 (rs187084), within the leukemia risk group.

The moss Syntrichia caninervis Mitt. is distributed throughout drylands globally, and often anchors ecologically significant communities known as biological soil crusts (biocrusts). The species occupies a variety of dryland habitats with varying levels of drought and temperature stress, suggesting the potential for ecological specialization within S.

Myopia is associated with interactive effects of genetic and environmental factors. The development of myopia in childhood is likely to be more dependent on genetic background. Candidate gene analysis, whole exome sequencing, genome-wide association studies (GWAS) and subsequent metaanalyses have identified more than 400 loci that are associated with myopia.

The transglutaminase (TGMs) family plays a crucial role in regulating mammalian reproduction, yet its impact on poultry reproductive traits has not been extensively studied. In this study, we identified eight members of the TGMs family in chickens and examined the contributions of genetic variations of coagulation factor XIII A chain (F13A1), transglutaminase 4 (TGM4), and LOC101749664 to selective breeding in commercial layers through genetic variation response pattern analysis. Transcriptome data from various tissues of high- and low-egg-yielding Gushi chickens revealed significant positive correlations between the mRNA expression levels of TGM4 and F13A1 genes and egg production (P < 0.
