Navigating the Complexity: A Comprehensive Review of GSK‐3 Inhibition in Regenerative Medicine

Medicinal Research Reviews, EarlyView.
ABSTRACT Glycogen synthase kinase‐3 (GSK‐3) is a central regulator of numerous cellular signaling pathways, with critical roles in metabolism, proliferation, differentiation, and tissue regeneration. This review explores the multifaceted effects of pharmacological GSK‐3 inhibition across multiple body districts, focusing on its highly context‐dependent

Case series: Kikuchi‐Fujimoto disease with diagnostic overlap

Rheumatology &Autoimmunity, EarlyView.
Kikuchi‐Fujimoto disease (KFD) is a rare, self‐limiting necrotizing lymphadenitis that poses significant diagnostic challenges due to its overlap with tuberculosis, systemic lupus erythematosus (SLE), and malignancy. We present four cases highlighting distinct diagnostic complexities: KFD mimicking tuberculosis with concomitant latent TB infection and ...

Oocyte-dependent activation of MTOR in cumulus cells controls the development and survival of cumulus-oocyte complexes.

, 2016
Communication between oocytes and their companion somatic cells promotes the healthy development of ovarian follicles, which is crucial for producing oocytes that can be fertilized and are competent to support embryogenesis.

Impact of sleep insufficiency and recovery on cancer development

Sleep Research, EarlyView.
Abstract Sleep plays a critical role in overall health, and modern lifestyles, such as shift work and late‐night activities, can significantly impact sleep condition. Insufficient sleep has been associated with various adverse health outcomes, including an increased risk of tumor development.

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 ...

Endometriosis disrupts oocyte metabolism and cortical granule function, impairing fertilization

Reproductive Biology and Endocrinology
Background Endometriosis is a chronic inflammatory disease strongly associated with reduced oocyte quality and subfertility, yet the underlying cytoplasmic defects remain poorly understood.
