MAPKK-dependent growth factor-induced upregulation of P2Y2 receptors in vascular smooth muscle cells
(1999) In Biochemical and Biophysical Research Communications 258(3). p.648-652- Abstract
- The ATP- and UTP-sensitive P2Y2 receptor which mediates both contractile and mitogenic effects has recently been shown to be upregulated in the synthetic phenotype of the vascular smooth muscle cell (VSMC). Using a competitive RT-PCR we demonstrate that the P2Y2 receptor mRNA is increased by fetal calf serum and other growth factors in a MAPKK-dependent way. This was confirmed at the functional level by examining UTP-stimulated release of intracellular Ca2+. Furthermore, the P2Y2 receptor mRNA is positively autoregulated by ATP and the mRNA is rapidly degraded with only 26% remaining after 1 h in the presence of actinomycin D. Our results indicate growth factor regulation and rapid turnover of the P2Y2 receptor mRNA, which may be of... (More)
