Cyclic GMP and PKG Signaling in Heart Failure

Frontiers in Pharmacology, 2022
Cyclic guanosine monophosphate (cGMP), produced by guanylate cyclase (GC), activates protein kinase G (PKG) and regulates cardiac remodeling. cGMP/PKG signal is activated by two intrinsic pathways: nitric oxide (NO)-soluble GC and natriuretic peptide (NP)

Neuron‐Targeted Exosomal Delivery of siRNA Against RIPK3 Slows Neurodegenerative Progression in Alzheimer's Disease

Advanced Science, EarlyView.
Engineered exosomal siRNA delivery platform enables systemic, neuron‐targeted RNA transport across the blood–brain barrier. Surface functionalization with rabies virus glycoprotein‐derived peptide facilitates receptor‐mediated transcytosis, achieving efficient cytosolic delivery and robust gene silencing. Targeting RIPK3 suppresses necroptosis, reduces

Transposable Element–Driven PIEZO Mutation Enhances Locust Flight in Plateau Hypoxia

Advanced Science, EarlyView.
Why transposable elements (TEs) persisted or expanded in genomes remains a mystery. Using integrated analysis of TE macro‐ and microevolution in locusts, our results showed that thousands of TE insertions promoted widespread adaptive variation. Subfamilies of candidate adaptive TEs amplified and reshaped species‐level genomic architecture.

The Role of cGMP-Dependent Protein Kinase in Controlling Cardiomyocyte cGMP [PDF]

Circulation Research, 2010
See related article, pages 1232–1240 The role of cGMP as a second messenger in physiological and pathophysiological processes is widely appreciated.1,–,3 The successes of drugs that target the cGMP-signaling pathway (nitrovasodilators and PDE5 inhibitors [sildenafil, tadalafil, vardenafil]) have inspired interest in other cardiovascular benefits that ...

Untangling Inositol (Pyro)Phosphate Biology Through Emerging Technologies

Advanced Science, EarlyView.
Inositol (pyro)phosphates represent a vital class of intracellular messengers that govern multiple biological processes. The last decade has experienced a surge of interest in the functions of this class of signaling molecules, primarily due to the introduction of several innovative analytical technologies.

Increased bioavailability of cyclic guanylate monophosphate prevents retinal ganglion cell degeneration

Neurobiology of Disease, 2019
The nitric oxide – guanylyl cyclase-1 – cyclic guanylate monophosphate (NO-GC-1–cGMP) pathway has emerged as a potential pathogenic mechanism for glaucoma, a common intraocular pressure (IOP)-related optic neuropathy characterized by the degeneration of ...

Rise of cGMP by partial phosphodiesterase-3A degradation enhances cardioprotection during hypoxia

Redox Biology, 2021
3′,5′-cyclic guanosine monophosphate (cGMP) is a druggable second messenger regulating cell growth and survival in a plethora of cells and disease states, many of which are associated with hypoxia. For example, in myocardial infarction and heart failure (

An Avalanche Effect Nanomodulator Triggers Cascade Ferroptosis/Cuproptosis for Immunosuppressive Microenvironment Remodeling

Advanced Science, EarlyView.
A nanomodulator called L‐Arginine/lificiguat@Copper‐hollow Prussian blue@Calcium phosphate nanoparticles is constructed to launch a self‐amplifying “avalanche effect” in tumor cells. The ensuing cascade, triggered by the acidic tumor microenvironment and near‐infrared light, induces calcium overload, generates a reactive oxygen species and reactive ...

Genome‐wide network analysis identifies the lncRNA‐92467/miR‐205‐5p/PTPRM/CAMs axis in a rat model of hypoxic pulmonary hypertension

Animal Models and Experimental Medicine, EarlyView.
The pathogenesis of hypoxic pulmonary hypertension (HPH) remains unclear. In this study, we explored its key regulatory mechanisms using animal models, RNA sequencing, and cellular assays. We found that lncRNA‐92467 functions as a ceRNA, binding miR‐205‐5p, and thereby upregulating PTPRM, inhibiting abnormal proliferation and migration of endothelial ...
