Abstract:
... Cold stress is an environmental cause of pulmonary hypertension syndrome (PHS) in broiler chickens. This factor could increase the rate of metabolic activity via thyroid hormones (T3 and T4). To evaluate the effect of these hormones on the heart, the plasma concentration of T3, T4, and the gene expression of their receptors (THRα and THRβ) and many contractile proteins (ACTC1, MHCα, MHCβ, RYR2, SE ...

Abstract:
... Multiple harmful factors cause chronic sub-lethal stress in managed honey bee colonies. In weak colonies, worker bees may not efficiently maintain the optimum temperature (33–36°C) in peripheral brood development areas. A short period at 25°C induces physiological adjustments and increases the mortality in honey bee brood reared in vitro. Molecular damage due to oxidative imbalance can be one of t ...

Abstract:
... How epigenetic memory states are established and maintained is a central question in gene regulation. A major epigenetic process important for developmental biology involves Polycomb-mediated chromatin silencing. Significant progress has recently been made on elucidating Polycomb silencing in plant systems through analysis of Arabidopsis FLOWERING LOCUS C (FLC). Quantitative silencing of FLC by pr ...

Abstract:
... Heat shock treatment of isolated microspore cultures (IMCs) at 32–33 °C for 1–3 days is almost the rule to induce microspore embryogenesis in most Brassica species. In this study, the effect of cold shock treatment of fresh IMCs on embryogenesis in ornamental kale was investigated. The open field-grown ‘Songbird Red’ F1 cultivar was used as donor plant. The microspores at mostly late unicellular s ...

We previously demonstrated that angiopoietin-like 8 (ANGPTL8) forms a localized complex with ANGPTL4 to reduce its lipoprotein lipase (LPL)-inhibitory activity and enable increased postprandial uptake of fatty acids (FA) into adipose tissue. Because prolonged cold exposure may increase adipose tissue FA uptake and decrease circulating triglycerides (TG) by reducing ANGPTL4 expression and inducing ...
