Effect of protamine and Its abnormalities on male fertility potential

مجله علمی دانشگاه علوم پزشکی کردستان, 2020
Background and Aim: All studies on mammals and rodents have revealed the presence of protamine 1 (P1) and protamine 2 (P2) in the sperm which is indicative of the expression of these two genes at different molecular levels.

Reproduction of the Azooxanthellate Coral Caryophyllia inornata Is Not Affected by Temperature Along an 850 km Gradient on the Western Italian Coast

Frontiers in Marine Science, 2020
The Intergovernmental Panel on Climate Change (IPCC) predicted that ocean surface temperature will rise of 0.6–2.0°C by 2100. Ocean warming is expected to produce strong impacts on marine ecosystems such as coral reefs, affecting their physiological ...

The genetic architecture of epilepsy across molecular mechanisms and clinical heterogeneity

Epilepsia Open, EarlyView.
Abstract Epilepsy comprises a highly heterogeneous group of neurological disorders unified by a persistent predisposition to recurrent seizures, yet driven by remarkably diverse genetic, molecular, and network‐level mechanisms. Advances in genomic technologies have revealed that epilepsy arises from a multilayered genetic architecture encompassing rare

Hepatic Mechanisms and Therapeutic Target Underpinning Hypercoagulation in Obesity: Insights From Genetic and Transcriptomic Analyses

Exploration, EarlyView.
Obesity‐linked hypercoagulation is driven by fibrinogen overproduction in a specific hepatocyte cluster via IL6 signalling. Genetic and mechanistic studies reveal this pathway as a key target for therapies to mitigate clotting risks and associated complications in obese individuals.

AtIRE1C, an unconventional isoform of the UPR master regulator AtIRE1, is functionally associated with AtIRE1B in Arabidopsis gametogenesis

Plant Direct, 2019
The unfolded protein response (UPR), a highly conserved set of eukaryotic intracellular signaling cascades, controls the homeostasis of the endoplasmic reticulum (ER) in normal physiological growth and situations causing accumulation of potentially toxic

Exploring vaginal microbiota–tissue resident stem cell crosstalk: VCAM1/Akt signaling ‐mediated enhancement of regenerative capacity

Interdisciplinary Medicine, EarlyView.
Vaginal microbiota‐derived secretory factors enhance the regenerative capacity of human endometrial stem cells by upregulating VCAM1 and activating PI3K/Akt signaling. This microbiota–stem cell crosstalk promotes self‐renewal, migration, multilineage differentiation, and metabolic reprogramming in vitro and in vivo, establishing a novel microbiota ...

Assessment of Oxidative Stress, Vitellogenin, and Human Health Risks Derived From Nile Tilapia Exposed to Metals and Metalloids in Southeastern Brazil

Environmental Toxicology, EarlyView.
ABSTRACT Urban coastal lagoons are highly vulnerable ecosystems increasingly affected by metal contamination, as well as multiple anthropogenic stressors. This study evaluated ecotoxicological and human health risks associated with chronic metal exposure in Nile tilapia (Oreochromis niloticus) from an anthropogenically impacted lagoon in southeastern ...
