Calcium Channel Blockers Inhibit Pancreatic Neuroendocrine Neoplasms Progression via Cav1.2‐Epigenetic Circuit

Advanced Science, EarlyView.
Our study reveals a novel mechanism of a positive regulatory circuit between Cav1.2 and H3K27ac for pancreatic neuroendocrine neoplasms (pNENs) progression. Cav1.2 is identified as a crucial target for promoting disease progression and correlates with malignant behaviors, which are remarkably inhibited by the administration of calcium channel blockers (

Decoding the Pathophysiology of Autoimmune Diseases—Mechanism, Triggers, and Nanotherapeutics: A Review

Advanced NanoBiomed Research, EarlyView.
This review highlights how autoimmune diseases arise from intertwined immunological, genetic, and environmental factors, emphasizing gut microbiota dysbiosis as a pivotal driver. It outlines emerging nanotechnology‐based strategies—such as liposomes, hydrogels, and polymeric nanoparticles—that enhance targeted drug delivery, minimize systemic toxicity,

A Novel Tolerogenic Antibody Targeting Disulfide-Modified Autoantigen Effectively Prevents Type 1 Diabetes in NOD Mice

Frontiers in Immunology, 2022
Increasing evidence suggested that the islet amyloid polypeptide (IAPP) is an essential autoantigen in the pathogenesis of type 1 diabetes (T1D) in humans and non-obese diabetic (NOD) mice.

Ca2+ binding to Chromaffin Vesicle Matrix Proteins [PDF]

, 1986
Recently we found that Ca2+ within chromaffin vesicles is largely bound [Bulenda, D., & Gratzl, M. (1985) Biochemistry 24, 7760-77651. In order to explore the nature of these bonds, we analyzed the binding of Ca2+ to the vesicle matrix proteins as well ...

C-terminal Domain of Chromogranin B Regulates Intracellular Calcium Signaling [PDF]

Journal of Biological Chemistry, 2011
The versatility of intracellular calcium as a second messenger is seen in its ability to mediate opposing events such as neuronal cell growth and apoptosis. A leading hypothesis used to explain how calcium regulates such divergent signaling pathways is that molecules responsible for maintaining calcium homeostasis have multiple roles.

Tissue Damage in Rheumatoid Arthritis is Genetically linked to Low Peptidylglycine Alpha‐Amidating Monooxygenase Activity in Synovial Fibroblasts

Arthritis &Rheumatology, Accepted Article.
Objectives Both susceptibility to, and severity of, rheumatoid arthritis (RA) is associated with the rs26232 C allele. Our primary aim was to identify the biological mechanism underlying this association. Methods Expression of surrounding genes was compared between rs26232 genotypes.

Synaptophysin and synaptoporin expression in the developing rat olfactory system [PDF]

, 1993
The expressions of two closely related synaptic vesicle antigens synaptophysin and synaptoporin were examined in the olfactory system of the adult rat and during pre- and postnatal development.
