TBPH-induced lung injury is induced by mitochondrial-derived ds-DNA-mediated inflammatory response.

Due to the ban on the use of traditional brominated flame retardants, new brominated flame retardants, such as Bis (2-ethylhexyl)-2,3,4,5-tetrabromophthalate (TBPH), have been developed as alternatives to traditional brominated flame retardants to replace the old ones, and TBPH has been widely used. Therefore, we need to systematically evaluate the toxicological effects of TBPH. In the current work, we analyzed the effects of TBPH on lung.

LCCP exposure leads to skin cell senescence damage by triggering oxidative stress mediated by mitochondrial Ca overload.

Currently, LCCP is widely present in environmental media as well as animal and human samples, suggesting that exposure to LCCP may have posed a threat to the health of animals and humans. Skin is one of the important pathways for LCCP exposure. To clarify the effects of LCCP exposure on the skin, we have utilized two skin cell models, HaCaT and L929, to investigate the complex impacts of LCCP exposure on skin cell senescence and its potential regulatory mechanism(s).

IPR1 is required for meiotic progression and embryonic development by regulating mitochondrial calcium and oxidative damage.

Calcium ions (Ca) regulate cell proliferation and differentiation and participate in various physiological activities of cells. The calcium transfer protein inositol 1,4,5-triphosphate receptor (IPR), located between the endoplasmic reticulum (ER) and mitochondria, plays an important role in regulating Ca levels. However, the mechanism by which IPR1 affects porcine meiotic progression and embryonic development remains unclear.

IPR1 regulates calcium balance in porcine oocyte maturation and early embryonic development.

The dynamic balance of Ca in oocytes promotes the recovery of the meiotic arrest phase, consequently promoting oocyte maturation. Hence, the analysis of the maintenance and role of calcium homeostasis in oocytes has important guiding significance for obtaining high-quality eggs and maintaining the development of preimplantation embryos. Inositol 1,4,5-trisphosphate receptors (IPRs) are calcium channel proteins that regulate the dynamic balance between the endoplasmic reticulum (ER) and mitochondrial Ca.

Effects of β-carotene supplementation in the diet of laying breeder hens on the growth performance and liver development of offspring chicks.

This experiment was conducted to evaluate the growth performance, growth regulating factors, and liver morphology of chicks hatched from egg-laying breeding hens dietary supplemented with additives (β-carotene). Hy-line breeding hens were allocated into three groups with three replicates/group. The dietary treatments were as follows: basal diet as a control (Con), basal diet supplemented with 120 (βc-L) or 240 (βc-H) mg/kg of β-carotene diet.

Maternal effects drive intestinal development beginning in the embryonic period on the basis of maternal immune and microbial transfer in chickens.

Background: Nutrition drives immunity and health in animals, and maternal immunity benefits offspring. In our previous study, a nutritional intervention strategy was found to promote the immunity of hens, which subsequently improved immunity and growth in offspring chicks. Maternal effects clearly exist, but how are mothers' immune advantages transferred to their offspring, and how do they benefit them?

Results: Here, we traced the beneficial effects back to the process of egg formation in the reproductive system, and we focused on the embryonic intestinal transcriptome and development, as well as on maternal microbial transfer in offspring.

Glycine regulates lipid peroxidation promoting porcine oocyte maturation and early embryonic development.

In vitro-cultured oocytes are separated from the follicular micro-environment in vivo and are more vulnerable than in vivo oocytes to changes in the external environment. This vulnerability disrupts the homeostasis of the intracellular environment, affecting oocyte meiotic completion, and subsequent embryonic developmental competence in vitro. Glycine, one of the main components of glutathione (GSH), plays an important role in the protection of porcine oocytes in vitro.

HBO1 as an Important Target for the Treatment of CCL4-Induced Liver Fibrosis and Aged-Related Liver Aging and Fibrosis.

The liver is the largest digestive organ in the human body. The increasing incidence of chronic liver fibrosis is one of the major health challenges in the world. Liver fibrosis is a wound-healing response to acute or chronic cellular damage of liver tissue.

The effect of growth hormone-induced cellular behavior and signaling properties on induced cellular senescence in human mesenchymal stem cells.

Senescence is associated with a decline in physiological function, which is accompanied by onset of diseases. Growth hormone (GH) is a class of growth-promoting cytokines with reduced secretion in aging populations. However, the effect of senescence on GH bioactivity is not fully understood in human mesenchymal stem cells (hMSCs).

The effect of heat stress on the epidermal growth factor (EGF)-mediated intracellular signaling, and changes cell behavior on swine testicular cell.

At present, high environmental temperature is the main factor endangering animal production, growth and development.

In this work, the cellar property and signaling property of epidermal growth factor (EGF) below heat stress remains unclear in swine testicular cells.

Glycine ameliorates MBP-induced meiotic abnormalities and apoptosis by regulating mitochondrial-endoplasmic reticulum interactions in porcine oocytes.

Monobutyl phthalate (MBP) is the main metabolite of dibutyl phthalate (DBP) in vivo. MBP has a stable structure, can continuously accumulate in living organisms, and has the potentially to harm animal and human reproductive function. In the ovarian follicle microenvironment, MBP may lead to defects in follicular development and steroid production, abnormal meiotic maturation, impaired ovarian function and other reproductive deficits.
