Exploring Epigenetic and Genetic Modulation in Animal Responses to Thermal Stress.

There is increasing evidence indicating that global temperatures are rising significantly, a phenomenon commonly referred to as 'global warming', which in turn is believed to be causing drastic changes to the global climate. Global warming (GW) directly impacts animal health, reproduction, production, and welfare, presenting several challenges to livestock enterprises. Thermal stress (TS) is one of the key consequences of GW, and all animal species, including livestock, have diverse physiological, epigenetic and genetic mechanisms to respond to TS.

Genomic characterization, phylogenetic and expression analysis of foraging gene in Apis mellifera.

The genomic characterization of the foraging gene and its expression analysis are required to better understand the behavior of honey bees (Apis mellifera). The present study performed a genome-wide characterization of the foraging gene, analyzing its physicochemical properties, phylogenetic features, and expression. An in silico analysis was carried out to characterize the foraging gene and the motifs and conserved domains of the encoded protein to predict its physicochemical properties.

Effects of mid-to-late prepartum feed supplementation in Hanwoo beef cows on their performance, blood metabolites, and the carcass characteristics and metabolites of their neonatal calves.

Introduction: This study aimed to evaluate the implications of supplementary nutrition during the mid-to-late pregnancy on various parameters in Hanwoo cows and their subsequent neonatal calves.

Materials And Methods: Eight Hanwoo cows in their first parity were divided into two groups. The control group (C, 100%) received 3kg of concentrate and 5kg of rice straw throughout the pregnancy period, while the treatment group (T, 150%) increased their diet during mid-to-late pregnancy.

Thyme extract could overcome diabetes-induced reproductive dysfunction by inhibiting oxidative damage and increasing the expression of insulin receptor substrate and pyruvate kinase in the rat sperm.

Objectives: Oxidative stress and disruption of energy metabolism in the reproductive system, especially sperm, play a significant role in diabetes-related infertility. Zataria multiflora Boissis (ZMB), a medicinal plant containing various bioactive compounds, may have efficacy in treating metabolic diseases and reproductive disorders. Therefore, the aim of this study was to investigate the effects of different doses of ZMB extract on diabetes-induced reproductive dysfunction by assessing oxidative damage and the gene expression of insulin receptor substrate (IRS) and pyruvate kinase (PK) in male rats' sperm.

The effects of apelin on IGF1/FSH-induced steroidogenesis, proliferation, Bax expression, and total antioxidant capacity in granulosa cells of buffalo ovarian follicles.

Apelin (APLN) was believed to be an adipokine secreted from adipose tissue. However, studies demonstrate that it is a pleiotropic peptide and has several effects on the female reproductive system. In this study, We examined the effects of different doses of IGF1 and FSH in the presence of APLN-13 on the production of progesterone in buffalo ovary granulosa cells.

Comparative Genomic Characterization of Relaxin Peptide Family in Cattle and Buffalo.

Relaxin family peptides significantly regulate reproduction, nutrient metabolism, and immune response in mammals. The present study aimed to identify and characterize the relaxin family peptides in cattle and buffalo at the genome level. The genomic and proteomic sequences of cattle, buffalo, goat, sheep, horse, and camel were accessed through the NCBI database, and BLAST was performed.

Comparative Genomic Characterization of Insulin-Like Growth Factor Binding Proteins in Cattle and Buffalo.

The somatotropic axis consists of genes associated with economic traits like muscle growth and carcass traits in livestock. Insulin-like growth factor binding proteins () are the major proteins that play a vital role in the somatotropic axis. The present study performed a genome-wide characterization of genes in cattle.

Nutrigenomic Interventions to Address Metabolic Stress and Related Disorders in Transition Cows.

For dairy cattle, the period involving a shift from late pregnancy to early lactation termed transition or periparturient is an excruciating phase. Health-related disorders are likely to happen in this time frame. Timely postpartum and metabolic adjustments to this new physical state demands correct management strategies to fulfill the cow's needs for a successful transition to this phase.

Positive Selection Drives the Adaptive Evolution of Mitochondrial Antiviral Signaling (MAVS) Proteins-Mediating Innate Immunity in Mammals.

The regulated production of filamentous protein complexes is essential in many biological processes and provides a new paradigm in signal transmission. The mitochondrial antiviral signaling protein (MAVS) is a critical signaling hub in innate immunity that is activated when a receptor induces a shift in the globular caspase activation and recruitment domain of MAVS into helical superstructures (filaments). It is of interest whether adaptive evolution affects the proteins involved in innate immunity.

Superior effect of broccoli methanolic extract on control of oxidative damage of sperm cryopreservation and reproductive performance in rats: A comparison with vitamin C and E antioxidant.

Sperm cryopreservation is one of the important reproductive biotechnology. However, during the sperm cryopreservation, reactive oxygen species (ROS) are produced which disrupt the functional and structural competence of sperm. The aim of this study is to compare the effects of broccoli extract with vitamins C and E on oxidative damage, sperm quality parameters, and reproductive hormones in rats.

Signatures of selection reveal candidate genes involved in production traits in Chinese crossbred buffaloes.

Identification of selection signature is important for a better understanding of genetic mechanisms that affect phenotypic differentiation in livestock. However, the genome-wide selection responses have not been investigated for the production traits of Chinese crossbred buffaloes. In this study, an SNP data set of 133 buffaloes (Chinese crossbred buffalo, n = 45; Chinese local swamp buffalo, n = 88) was collected from the Dryad Digital Repository database (https://datadryad.

Cysteamine administration in lambs grazing on mountain pastures: Effects on the body weight, antioxidant capacity, thyroid hormones and growth hormone secretion.

This study aimed to evaluate the effects of intravenous injection of cysteamine (CS) on body weight (BW), growth hormone (GH), thyroid hormones (TH) secretion, and antioxidant status of growing lambs grazing on mountain pastures. Fifteen lambs (3-4 months of age) were randomly allocated into three experimental groups which received different dosages of CS: 0, 20, and 50 mg/kg BW . The CS was injected on the 1st, 10th and 20th days of the experiment to the lambs through the jugular vein.

Reproductive roles of novel adipokines apelin, visfatin, and irisin in farm animals.

The adipose tissue has a substantial impact on reproduction in mammals, specifically in females. As an energy depository organ, it is precisely associated with the reproductive success of mammals. Adipose tissue secretes many single molecules that are called 'adipokines' which mainly act as endocrine hormones.

Smart edible films based on mucilage of seed incorporated with curcumin for freshness monitoring.

In the current study, the pattern of HSP70 gene transcription, foraging, and temperature inside and outside the hive and their association in Apis mellifera meda colonies during Ziziphus blooming period were investigated. Therefore, the number of bees entering the hive, temperature inside and outside the hive were recorded in six colonies at different times of the day.

No polymorphism of melatonin receptor 1A (MTNR1A) gene was found in Markhoz goat.

Melatonin is the main hormone of seasonal breeding in sheep and goat which has an effect on reproductive organs via its receptors. Studies have shown that mutations in melatonin receptor 1A (MTNR1A) gene are related to litter size as well as the ovulation rate in sheep and goats. In this study, polymorphism of two loci in MTNR1A melatonin receptor gene was studied in order to survey their relationship with litter size in Markhoz goats.
