Abstract |
Within 24 h four peptide hormones, i.e. vessel dilator, long acting natriuretic peptide, kaliuretic peptide, and atrial natriuretic peptide and their intracellular mediator cyclic GMP decreased the number of human squamous lung cancer cells 51, 22, 25, 21, and 30%, respectively. There was not any proliferation in the 3 days following this decrease in cell number. Vessel dilator decreased DNA synthesis 85% in the squamous lung cancer cells. Thus, vessel dilator significantly decreased the number of human squamous lung cancer cells and their DNA synthesis, mediated in part by cyclic GMP, more than other peptide hormones.
