Alterations of Phosphodiesterases in Adrenocortical Tumors [PDF]

Frontiers in Endocrinology, 2016
Alterations in the cyclic (c)AMP-dependent signaling pathway have been implicated in the majority of benign adrenocortical tumors (ACTs) causing Cushing syndrome (CS). Phosphodiesterases (PDEs) are enzymes that regulate cyclic nucleotide levels, including cyclic adenosine monophosphate (cAMP).

Selective Phosphodiesterase 4B Inhibitors: A Review

Scientia Pharmaceutica, 2014
Phosphodiesterase 4B (PDE4B) is a member of the phosphodiesterase family of proteins that plays a critical role in regulating intracellular levels of cyclic adenosine monophosphate (cAMP) by controlling its rate of degradation.

Sonoepigenetic Modification Mechanoprimes Early Osteogenic Commitment in Mesenchymal Stem Cells

Advanced Science, EarlyView.
Brief 10 min bursts of high frequency (10 MHz) vibrational mechanostimulation to stem cells are shown to activate their epigenetic machinery to condition their differentiation down an osteogenic lineage within just 3 days, which is much earlier than that with other forms of mechanostimuli, and without requiring any biochemical additives.

Rv2577 of Mycobacterium tuberculosis Is a Virulence Factor With Dual Phosphatase and Phosphodiesterase Functions

Frontiers in Microbiology, 2020
Tuberculosis, a lung disease caused by Mycobacterium tuberculosis (Mtb), is one of the ten leading causes of death worldwide affecting mainly developing countries. Mtb can persist and survive inside infected cells through modulation of host antibacterial

Mammalian Glycerophosphodiester Phosphodiesterases [PDF]

Bioscience, Biotechnology, and Biochemistry, 2007
Bacterial glycerophosphodiester phosphodiesterases (GP-PDEs), GlpQ and UgpQ, are well-characterized periplasmic and cytosolic proteins that play critical roles in the hydrolysis of deacylated glycerophospholipids to glycerol phosphate and alcohol, which are utilized as major sources of carbon and phosphate.

Phosphodiesterase-5 inhibition augments endogenous antitumor immunity by reducing myeloid-derived suppressor cell function

Journal of Experimental Medicine, 2006
Phosphodiesterase-5 (PDE5) inhibitors (sildenafil, tadalafil, and vardenafil) are agents currently in clinical use for nonmalignant conditions. We report the use of PDE5 inhibitors as modulators of the antitumor immune response.

Inhibition of Macrophage ARID3A Alleviates Myocardial Ischemia‐Reperfusion Injury After Heart Transplantation by Reducing THBS1/CD47 Signaling‐Mediated Neutrophil Extracellular Traps Formation

Advanced Science, EarlyView.
This study reveals that ARID3A in macrophages can transcriptionally regulate the THBS1‐CD47 axis after heart transplantation (HT), thereby inducing activated neutrophils to release NETs through the p38 MAPK signaling pathway. The itaconate derivative 4‐OI can inhibit ARID3A in macrophages and promote the accumulation of antioxidant factors, thereby ...

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.

PIEZO Force Sensing in Vascular Biology: An Explosion of New Knowledge, Concepts and Opportunity

Advanced Science, EarlyView.
Knowledge of the remarkable mechanical force sensing and electrically transducing PIEZO1 and PIEZO2 channels is discussed across vascular biology and its cell types from the embryonic to adult stages in health, disease and old age. How the channels work, relate to other factors and signal for tissue responses to mechanical forces is debated.
