چکیده انگلیسی
Results show that organ culture per se induced transcriptional upregulation of contractile ETB receptors in the cerebral vascular smooth muscle cells. This upregulation was further increased at the translational level by addition of DSP to the organ culture, but this increase was not seen by addition of nicotine or water-soluble cigarette smoke particles to the organ culture. The increased upregulation of contractile ETB receptors by DSP was abrogated by U0126, SP600125, actinomycin D, and cycloheximide, suggesting that the underlying molecular mechanisms involved in this process include activation of MEK and JNK MAPK-mediated transcription and translation of new contractile ETB receptors. Thus, the MAPK-mediated upregulation of contractile ETB receptors in cerebral arteries might be a pharmacological target for the treatment of smoke-associated cerebral vascular disease like stroke.
