  • Title: Nitric oxide-releasing compounds inhibit Dictyostelium discoideum aggregation without altering cGMP production.
    Author: Tao Y, Howlett A, Klein C.
    Journal: FEBS Lett; 1992 Dec 07; 314(1):49-52. PubMed ID: 1360411.
    Abstract:
    The effects of nitric oxide-releasing compounds on Dictyostelium discoideum cell development and guanylyl cyclase activity were studied. The addition of SNP (sodium nitroprusside) or SIN-1 (3-morpholino-syndnonimine) to starved cells inhibited their differentiation and aggregation in a concentration-dependent manner. In contrast to mammalian systems, SNP did not significantly affect guanylyl cyclase activity in cell lysates of D. discoideum, nor did it stimulate cGMP production in intact cells. The results suggest that the inhibitory effects of NO on D. discoideum cell aggregation are through a mechanism independent of an effect on guanylyl cyclase activity.
