ZFP36L2 Role in Thyroid Functionality

Neonicotinoids, a relatively new widely used class of insecticide is used in agriculture to control insect populations. We examined the capacity of ancestral exposure to the neonicotinoid thiacloprid (thia) to induce transgenerational effects on thyroid tissue. Pregnant outbred Swiss female mice were exposed to thia at embryonic days E6.5 to E15.5 using 0, 0.6, and 6 mg/kg/day doses. Thyroid paraffin sections were prepared for morphology analysis. We apply ELISA method to measure T4 and TSH levels, RT-qPCR for gene expression analysis, ChIP-qPCR techniques for sperm histone H3K4me3 analysis, and immunofluorescence microscopy and western blots for protein detection. We observed an alteration in the morphology of thyroids in both males and females in the F3 generation. We observed an increase in T4 hormone in F1 females and a significant T4 level decrease in F3 males. T4 changes in F1 females were associated with a TSH increase. We found that the amount of Iodothyronine Deiodinase 1 (DIO1) (an enzyme converting T4 to T3) was decreased in both F1 and F3 generations in female thyroids. GNAS protein which is important for thyroid function has increased in female thyroids. Gene expression analysis showed that the expression of genes encoding thyroid gland development, chromatin, biosynthesis and transport factors were affected in the thyroid gland in both sexes in F1 and F3. The analysis of sperm histone H3K4me3 showed that H3K4me3 occupancy at the Dio1 locus has decreased while Thyroglobulin (Tg) and Matrix Metallopeptidase 2 (Mmp2) genes have increased H3K4me3 occupancy in the sperm of F3 mice. Besides, DNA methylation analysis of our previously published datasets showed that, in the sperm of F1 and F3 thia-derived mice, several genes related to thyroid function show consistent alterations. Our data suggest that ancestral exposure to thiacloprid affects thyroid function not only in exposed but also in indirectly exposed F3 generation.

A higher body weight at a younger age is an economically important trait for profitable goat farming. This study was focused on the identification of regions of the genome that harbor genetic variants associated with body weight using the Illumina GoatSNP50K Bead Chip. A total of 631 purebred Beetal goats (151 males and 480 females) were recorded for body weight, age and body measurement and then genotyped. Genome wide association analysis was carried out with GEMMA. After application of quality control filters with Plink 1.9, call rate less or equal than 0.9, minor allele frequency less than 0.05 and HWE P value lesser than 0.001, 594 animals and 45,744 SNPs were retained for association analysis. The association analysis for body weight with covariates of age, sex and morphometric measurements and contemporary group yielded 10 significant SNPs (P = -log10e-4 to -log10e-6). Three associated SNPs were within genes i.e., BTAF1, NTM and GRID1 when blasted against ARS1(accession GCA_001704415.1). Moreover, some associated SNPs were localized close to CEP78, ROBO1, ZFP36L2, SPTLC3, CTR9 and ZFHX3 genes. The study identified SNPs and genes with potential role in growth of goat.
