The aim of this work was to identify cis-regulatory sequences within the Chlamydomonas HSP70A promoter that mediate its stimulatory effect on the expression of downstream promoters. For this, we deleted/mutated the HSP70A promoter and, using a new assay, quantified its stimulatory effect. Our results indicate that the effect is mediated largely by heat shock elements and the TATA box.

Chronic oxidative stress (COS) is related to the pathophysiology of the trabecular meshwork (TM) in glaucoma. MicroRNAs (miRNAs) have a key role in the oxidative stress-mediated glaucoma. This work investigated the function of miR-126-5p in human trabecular meshwork cells (TMCs) under chronic oxidative stress (COS).

Meagre () is one of the fast-growing species considered for sustainable aquaculture development along the Mediterranean and Eastern Atlantic coasts. The emergence of Systemic Granulomatosis (SG), a disease marked by multiple granulomas in various tissues, poses a significant challenge in meagre aquaculture. In the current study, we investigate the association of spp.

is a typical aroma-producing yeast in food brewing, but it has low heat resistance and poor proliferation ability at high temperature. Trehalose is generally considered to be a protective agent that helps stable yeast cells resist heat shock stress, but its functional mechanism for yeast cells in the adaptation period under heat stress is unclear. In this study, the physiological metabolism changes, specific gene transcription expression characteristics, and transcriptome differences of under different carbon sources under high-temperature stress (40 °C) were compared to explore the mechanism of trehalose inducing to recover and proliferate under high-temperature stress during the adaptation period.

Heat stress poses a significant challenge to animal husbandry, contributing to oxidative stress, intestinal mucosal injury, and apoptosis, which severely impact animal health, growth, and production efficiency. The development of safe, sustainable, and naturally derived solutions to mitigate these effects is critical for advancing sustainable agricultural practices. Butyrolactone-I (BTL-I), a bioactive compound derived from deep-sea fungi (Aspergillus), shows promise as a functional feed additive to combat heat stress in animals.
