Phosphorylation of Bok at Ser-8 blocks its ability to suppress IPR-mediated calcium mobilization.
Cell Commun Signal
January 2025
Department of Pharmacology, SUNY Upstate Medical University, Syracuse, NY, 13210, USA.
Background: Bok is a poorly characterized Bcl-2 protein family member with roles yet to be clearly defined. It is clear, however, that Bok binds strongly to inositol 1,4,5-trisphosphate (IP) receptors (IPRs), which govern the mobilization of Ca from the endoplasmic reticulum, a signaling pathway required for many cellular processes. Also known is that Bok has a highly conserved phosphorylation site for cAMP-dependent protein kinase at serine-8 (Ser-8).

January 2025
Faculty of Dentistry, Department of Restorative Dentistry, Çanakkale Onsekiz Mart University, Çanakkale, 17100, Turkey.
Objectives: This study aimed to evaluate the effectiveness of home-use desensitizing agents over an 8-week period by comparing them using different measurement methods.
Methods: A randomized, controlled clinical trial was conducted with 180 individuals aged between 18 and 70 who clinically diagnosed dentin hypersensitivity (DH) in two or more non-adjacent teeth. Subjects who met the inclusion criteria (n = 164) were randomly allocated into five test groups-using Casein phosphopeptide-amorphous calcium phosphate (CPP-ACP), Arginine, Novamin, Propolis, and Potassium nitrate-and a control group using standard fluoride toothpaste.
Spaceflight alters protein levels and gene expression associated with stress response and metabolic characteristics in human cardiac spheroids.

Cardiomyocytes derived from human induced pluripotent stem cells (hiPSC-CMs) possess tremendous advantage for cardiac regeneration. However, cell survival is challenging upon cell transplantation. Since microgravity can profoundly affect cellular properties, we investigated the effect of spaceflight on hiPSC-CMs.

January 2025
Hangzhou Third People's Hospital, Hangzhou, China.
Background: Post-inflammatory hyperpigmentation (PIH) is a common cosmetic concern, often leading to significant psychological distress for the patients. With the widespread application of lasers including ablative fractional resurfacing (AFR) with a 10,600 nm CO laser, PIH caused by lasers is becoming increasingly common. But due to the absence of an appropriate animal research model, our understanding of pathophysiological mechanisms and preventive strategies for PIH remains limited.

Alzheimers Res Ther
January 2025
Radiology Department, Second Affiliated Hospital of Shantou University Medical College, Shantou, Guangdong, China.
Background: The imbalance of glutamate (Glu) and gamma-aminobutyric acid (GABA) neurotransmitter system plays a crucial role in the pathogenesis of Alzheimer's disease (AD). Riluzole is a Glu modulator originally approved for amyotrophic lateral sclerosis that has shown potential neuroprotective effects in various neurodegenerative disorders. However, whether riluzole can improve Glu and GABA homeostasis in AD brain and its related mechanism of action remain unknown.
