Genetically Encoded Biosensors Reveal PKA Hyperphosphorylation on the Myofilaments in Rabbit Heart Failure [PDF]

, 2016
RATIONALE: In heart failure, myofilament proteins display abnormal phosphorylation, which contributes to contractile dysfunction. The mechanisms underlying the dysregulation of protein phosphorylation on myofilaments is not clear.

Determination of Phosphodiesterase Type-5 Inhibitors (PDE-5) in Dietary Supplements

Molecules, 2023
This study proposed a high-performance thin-layer chromatography (HPTLC) screening method to detect phosphodiesterase 5 (PDE-5) inhibitors as possible adulterant agents in various dietary supplements. Chromatographic analysis was performed on silica gel 60F254 plates using a mixture of ethyl acetate:toluene:methanol:ammonia in a volume ratio of 50:30 ...

Palmitoylation‐Mediated Ubiquitination of SRPK1 Regulates Ferroptosis in High‐Fat‐Induced Erectile Dysfunction

Advanced Science, EarlyView.
Elevated exogenous palmitic acid promotes the S‐palmitoylation of SRPK1 in endothelial cells, a dynamic process governed by ZDHHC24 and APT1. This post‐translational modification strengthens the interaction between SRPK1 and the E3 ubiquitin ligase MIB1, thereby facilitating the proteasomal degradation of SRPK1.

Effects of High Flavanol Dark Chocolate on Cardiovascular Function and Platelet Aggregation. [PDF]

, 2015
Regular consumption of chocolate and cocoa products has been linked to reduced cardiovascular mortality. This study compared the effects of high flavanol dark chocolate (HFDC; 1064mg flavanols/day for 6 weeks) and low flavanol dark chocolate (LFDC; 88mg ...

Resolvin D5 Inhibits CXCL8 Expression in Colonic Epithelial Cells Through Activating GPR101 to Impede Neutrophil Recruitment and Consequently Alleviate Ulcerative Colitis

Advanced Science, EarlyView.
RvD5 effectively alleviates UC by inhibiting STAT1 signaling to reduce CXCL8 expression in colonic epithelial cells via activation of GPR101, which subsequently decreases the infiltration of neutrophils in the colonic mucosal epithelium. Epimedin A1, a natural allosteric inhibitor of 5‐LOX, demonstrates potential as a therapeutic agent for UC by ...

RPS3‐Enriched Extracellular Vesicles Mediate Liver‐Spinal Cord Inter‐Organ Communication

Advanced Science, EarlyView.
Spinal cord injury activates the liver to send extracellular vesicles loaded with RPS3 protein to the lesion site. These vesicles are taken up by neural stem cells and astrocytes, triggering NF‐κB signaling, impairing the regeneration of neurons and myelin, and promotes harmful inflammation, ultimately hindering recovery.

AXL Promotes Ischemic Myelin Repair Through Alleviating Myelin Debris Deposition and Lipid Droplets Accumulation

Advanced Science, EarlyView.
Microglial AXL drives white matter repair after stroke by orchestrating the cleanup of myelin debris. Mechanistically, AXL signals through EGR1 to boost Smpd1 transcription, regulating sphingolipid metabolism and preventing lipid droplet toxicity. Restoring the pathway with ASM therapy mitigates damage, positioning AXL as a key node for therapeutic ...

Tadalafil Treatment Delays the Onset of Cardiomyopathy in Dystrophin‐Deficient Hearts

Journal of the American Heart Association: Cardiovascular and Cerebrovascular Disease, 2016
BackgroundCardiomyopathy is a leading cause of mortality among Duchenne muscular dystrophy patients and lacks effective therapies. Phosphodiesterase type 5 is implicated in dystrophic pathology, and the phosphodiesterase type 5 inhibitor tadalafil has ...
