Mitochondrial Calcium Increase Induced by RyR1 and IP3R Channel Activation After Membrane Depolarization Regulates Skeletal Muscle Metabolism

Frontiers in Physiology, 2018
Aim: We hypothesize that both type-1 ryanodine receptor (RyR1) and IP3-receptor (IP3R) calcium channels are necessary for the mitochondrial Ca2+ increase caused by membrane depolarization induced by potassium (or by electrical stimulation) of single ...

Autophosphorylation of inositol 1,4,5-trisphosphate receptors.

Journal of Biological Chemistry, 1992
Inositol 1,4,5-trisphosphate (IP3) releases internal stores of calcium by binding to a specific membrane receptor which includes both the IP3 recognition site as well as the associated calcium channel. The IP3 receptor is regulated by ATP, calcium, and phosphorylation by protein kinase A, protein kinase C, and calcium/calmodulin-dependent protein ...

Relationship between membrane phosphatidylinositol-4,5-bisphosphate and receptor-mediated inhibition of native neuronal M channels [PDF]

, 2005
The relationship between receptor-induced membrane phosphatidylinositol-4'5'-bisphosphate (PIP2) hydrolysis and M-current inhibition was assessed in single-dissociated rat sympathetic neurons by simultaneous or parallel recording of membrane current and ...

Choline Is an Intracellular Messenger Linking Extracellular Stimuli to IP3-Evoked Ca2+ Signals through Sigma-1 Receptors

Cell Reports, 2019
Summary: Sigma-1 receptors (Sig-1Rs) are integral ER membrane proteins. They bind diverse ligands, including psychoactive drugs, and regulate many signaling proteins, including the inositol 1,4,5-trisphosphate receptors (IP3Rs) that release Ca2+ from the

Exploring the Impact of Urolithins A and B on Muscle Health: A Transcriptomic Analysis in Human Myotubes

Journal of Cachexia, Sarcopenia and Muscle, Volume 17, Issue 5, October 2026.
ABSTRACT Background Urolithin A (UA) and urolithin B (UB) are gut microbiota‐derived metabolites of ellagitannins reported to influence mitochondrial function, inflammation and muscle metabolism. Their comparative transcriptomic effects in human skeletal muscle cells remain undefined.

Degradation of inositol 1,3,4,5-tetrakisphosphates by porcine brain cytosol yields inositol 1,3,4-trisphosphate and inositol 1,4,5-trisphosphate

, 1988
Inositol 1,3,4,5-tetrakisphosphates (Ins(1,3,4,5)P4), 32P-labelled in positions 4 and 5 were prepared enzymatically, using [4-32P]-phosphatidylinositol 4-phosphate (PtdInsP) and [5-32P]phosphatidylinositol 4,5-bisphosphate (PtdInsP2) as substrates ...

The Bcl-2 Protein Family Member Bok Binds to the Coupling Domain of Inositol 1,4,5-Trisphosphate Receptors and Protects Them from Proteolytic Cleavage [PDF]

, 2013
Bok is a member of the Bcl-2 protein family that controls intrinsic apoptosis. Bok is most closely related to the pro-apoptotic proteins Bak and Bax, but in contrast to Bak and Bax, very little is known about its cellular role.

The Role of Neuropeptide Y in Dental Pulp: Balancing Neurogenic Inflammation and Pain Modulation

International Endodontic Journal, Volume 59, Issue 10, Page 2028-2045, October 2026.
ABSTRACT Background Dental pulp is a densely innervated, low‐compliance tissue in which neurogenic inflammation can rapidly escalate into oedema, raised intrapulpal pressure, microvascular compromise, and pain. While Substance P (SP) and Calcitonin gene‐related peptide (CGRP) are well‐established drivers of pulp vasodilation, the Neuroopeptide Y (NPY ...

Ca2+ Release by IP3 Receptors Is Required to Orient the Mitotic Spindle

Cell Reports, 2020
Summary: The mitotic spindle distributes chromosomes evenly to daughter cells during mitosis. The orientation of the spindle, guided by internal and external cues, determines the axis of cell division and thereby contributes to tissue morphogenesis ...

Relaxin‐2: Shaping the Proteomic Landscape of Skeletal Muscle Physiology, Glucose Trafficking, and Mitochondrial Function in Rat

The FASEB Journal, Volume 40, Issue 18, 30 September 2026.
Cardioprotective hormone relaxin‐2 showed relevant effects on rat skeletal muscle by altering proteins linked to muscle function, regeneration, differentiation, mitochondrial function, glucose metabolism, and structural integrity and organization. Specifically, relaxin‐2 reduced the expression of 95 proteins, increased 32, and elicited unique proteins ...
