Resveratrol, a polyphenolic constituent of red wine, is known for its anti-atherogenic properties and is thought to be beneficial in reducing the incidence of cardiovascular diseases (CVD). However, the mechanism of action by which it exerts its anti-atherogenic effect remains unclear. In this study, we investigated the relationship between the antioxidant… (More)
UNLABELLED MtbRegList is a database dedicated to the analysis of gene expression and regulation data in Mycobacterium tuberculosis. It is designed to contain predicted and characterized regulatory DNA motifs cross-referenced with corresponding transcription factor(s), and experimentally identified transcription start sites. MtbRegList can also handle… (More)
Heterotopic ossification (HO) is defined as the formation of bone inside soft tissue. Symptoms include joint stiffness, swelling, and pain. Apart from the inherited form, the common traumatic form generally occurs at sites of injury in damaged muscles and is often associated with brain injury. We investigated bone morphogenetic protein 9 (BMP-9), which… (More)
Skeletal muscle atrophy is a serious concern for patients afflicted by limb restriction due to surgery (e.g., arthrodesis), several articular pathologies (e.g., arthralgia), or simply following cast immobilization. To study the molecular events involved in this immobilization-induced debilitating condition, a convenient mouse model for atrophy is lacking.… (More)
The stiffness of the myogenic stem cell microenvironment markedly influences the ability to regenerate tissue. We studied the effect of damaged myofibers on myogenic progenitor cell (MPC) proliferation and determined whether the structural integrity of the microenvironment contributes to phenotypic changes. Individual myofibers were isolated and cultured… (More)
BACKGROUND Skeletal muscle aging is associated with a decreased regenerative potential due to the loss of function of endogenous stem cells or myogenic progenitor cells (MPCs). Aged skeletal muscle is characterized by the deposition of extracellular matrix (ECM), which in turn influences the biomechanical properties of myofibers by increasing their… (More)
We demonstrated in a previous study that murine double minute (Mdm)-2 is essential for exercise-induced skeletal muscle angiogenesis. In the current study, we investigated the mechanisms that regulate Mdm2 activity in response to acute exercise and identified VEGF-A as a key stimulator of Mdm2 phosphorylation on Ser(166) (p-Ser166-Mdm2). VEGF-A and… (More)

Apoptotic pathways in breast cancer cells are frequently altered, reducing the efficiency of radiotherapy. Conjugated linoleic acid (CLA), known to trigger apoptosis, was tested as radiosensitizer in breast cancer cells MCF-7 and MDA-MB-231. The CLA-mix, made up of the isomers CLA-9cis 11trans and CLA-10trans 12cis, was compared to three purified isomers,… (More)
