In both colon cancer and type 2 diabetes, metabolic changes induced by upregulation of the Wnt/beta-catenin signaling and downregulation of peroxisome proliferator-activated receptor gamma (PPAR gamma) may help account for the frequent association of these two diseases. In both...

PMID: 11390883
News Physiol Sci. 2000 Apr;15:78-83. doi: 10.1152/physiologyonline.2000.15.2.78.

Rapid and complete relaxation is a prerequisite for cardiac output adaptation to changes in loading conditions, inotropic stimulation, and heart rate. In the healthy human heart, the rate and extent of relaxation depend mainly on actomyosin cross bridge dissociation...

Cardiac cells interact with the extracellular matrix (ECM) proteins through integrin mechanoreceptors that control many cellular events such as cell survival, apoptosis, differentiation, migration, and proliferation. Integrins play a crucial role in cardiac development as well as in cardiac...

Possible Treatment of Myocardial Infarct Based on Tissue Engineering Using a Cellularized Solid Collagen Scaffold Functionalized with Arg-Glyc-Asp (RGD) Peptide.

PMID: 34830447
Int J Mol Sci. 2021 Nov 22;22(22). doi: 10.3390/ijms222212563.

Currently, the clinical impact of cell therapy after a myocardial infarction (MI) is limited by low cell engraftment due to low cell retention, cell death in inflammatory and poor angiogenic infarcted areas, secondary migration. Cells interact with their microenvironment...

Circadian rhythms, Wnt/beta-catenin pathway and PPAR alpha/gamma profiles in diseases with primary or secondary cardiac dysfunction.

Frontiers in physiology

Lecarpentier Y, Claes V, Duthoit G, Hébert JL.
PMID: 25414671
Front Physiol. 2014 Nov 04;5:429. doi: 10.3389/fphys.2014.00429. eCollection 2014.

Circadian clock mechanisms are far-from-equilibrium dissipative structures. Peroxisome proliferator-activated receptors (PPAR alpha, beta/delta, and gamma) play a key role in metabolic regulatory processes, particularly in heart muscle. Links between circadian rhythms (CRs) and PPARs have been established. Mammalian CRs...

TGF-β in fibrosis by acting as a conductor for contractile properties of myofibroblasts.

Cell & bioscience

Vallée A, Lecarpentier Y.
PMID: 31827764
Cell Biosci. 2019 Dec 09;9:98. doi: 10.1186/s13578-019-0362-3. eCollection 2019.

Myofibroblasts are non-muscle contractile cells that play a key physiologically role in organs such as the stem villi of the human placenta during physiological pregnancy. They are able to contract and relax in response to changes in the volume...

Opposite Interplay between PPAR Gamma and Canonical Wnt/Beta-Catenin Pathway in Amyotrophic Lateral Sclerosis.

Frontiers in neurology

Lecarpentier Y, Vallée A.
PMID: 27445967
Front Neurol. 2016 Jun 28;7:100. doi: 10.3389/fneur.2016.00100. eCollection 2016.

The opposite interplay between peroxisome proliferator-activated receptor gamma (PPAR gamma) and Wnt/beta-catenin signaling has led to the categorization of neurodegenerative diseases (NDs) as either NDs in which PPAR gamma is downregulated while the canonical Wnt/beta-catenin pathway is upregulated [amyotrophic...
