Roundup is a glyphosate-based herbicide used worldwide, including on most genetically modified plants that have been designed to tolerate it. Its residues may thus enter the food chain, and glyphosate is found as a contaminant in rivers. Some agricultural workers using glyphosate have pregnancy problems, but its mechanism of action in mammals is questioned.(More)
Type II collagen is a marker of articular cartilage encoded by the COL2A1 gene. The nature of the trans factors involved in the upregulation of this gene by insulin-like growth factor-I (IGF-I) remains unclear. We found that IGF-I increased type II collagen synthesis by a transcriptional control mechanism involving a 715-bp region within the COL2A1(More)
The existence of a link between estrogen deprivation and osteoarthritis (OA) in postmenopausal women suggests that 17β-estradiol (17β-E2) may be a modulator of cartilage homeostasis. Here, we demonstrate that 17β-E2 stimulates, via its receptor human estrogen receptor α 66 (hERα66), type II collagen expression in differentiated and dedifferentiated(More)
