Characterization of a Unique Muscle Cell Line
A clonal cell line derived from a mouse neoplasm is described which shares many properties with smooth muscle. The cells have electrically excitable membranes capable of generating overshooting action potentials, and they contract both spontaneously and with electrical stimulation. They respond to the iontophoretic application of acetylcholine with a depolarizing response, and to norepinephrine...
متن کاملVascular circadian rhythms in a mouse vascular smooth muscle cell line (Movas-1).
The circadian system in mammals is a hierarchy of oscillators throughout the organism that are coordinated by the circadian clock in the hypothalamic suprachiasmatic nucleus. Peripheral clocks act to integrate time-of-day information from neural or hormonal signals, regulating gene expression, and, subsequently, organ physiology. However, the mechanisms by which the central clock communicates w...
متن کامل"FRNKly, smooth muscle, I don't give a CArG!": a novel mechanism for smooth muscle cell differentiation.
Studies spanning the last two decades have begun to uncover the molecular mechanisms underlying smooth muscle cell (SMC) differentiation, specifically the critical role of the ubiquitously expressed serum response factor (SRF) transcription factor. SRF selectively binds to conserved cis-regulatory “CArG box” elements, CC(A/T)6GG consensus sequence, in the promoters or first introns of numerous ...
متن کاملCharacterization of myosin heavy chains in cultured aorta smooth muscle cells. A comparative study.
Myosin heavy chains (MHCs) from rat aorta smooth muscle cells were analyzed prior to and after these cells were placed into cell culture using sodium dodecyl sulfate-5% polyacrylamide gels, immunoblots, and two-dimensional peptide maps of tryptic digests. Rat aorta smooth muscle cells prior to culture were found to contain two MHCs (mass = 204 and 200 kDa) which cross-reacted with antibodies ra...
متن کاملA delayed ATP-elicited K+ current in freshly isolated smooth muscle cells from mouse aorta.
Adenosine 5'-triphosphate (ATP) activated two sequential responses in freshly isolated mouse aortic smooth muscle cells. In the first phase, ATP activated Ca(2+)-dependent K(+) or Cl(-) currents and the second phase was the activation of a delayed outward current with a reversal potential of -75.9 +/- 1.4 mV. A high concentration of extracellular K(+) (130 mM) shifted the reversal potential of ...
