R Kettritz, R J Falk, J C Jennette, M L Gaid. Neutrophil superoxide release is required for spontaneous and FMLP-mediated but not for TNF alpha-mediated apoptosis. Journal of the American Society of Nephrology : JASN. vol 8. issue 7. 1997-09-24. PMID:9219158. |
pmn apoptosis was detected by dna fragmentation, and ultraviolet and light microscopy, and was quantified by flow cytometry; superoxide release was measured by superoxide dismutase-inhibitable reduction of ferricytochrome c. incubation of pmn with 20 ng/ml tumor necrosis factor (tnf)alpha induced superoxide release (8.8 +/- 7.5 nmol o2-/30 min, n = 7) in normal pmn and also resulted in apoptosis within 2 h, whereas a subactivating dose of 2 ng/ml tnf alpha, which did not trigger superoxide release (3.1 +/- 1.7 nmol o2-, n = 10), did facilitate apoptosis, although to a lesser degree. |

using various rar- and rxr-specific analogs and antagonists, it was demonstrated that stimulation of rar alpha inhibits the rargamma-specific death pathway (which explains the lack of apoptosis stimulatory effects of all-trans retinoic acid at physiological concentrations) and that costimulation of the rxr receptors (in the case of 9-cis retinoic acid) can neutralize this inhibitory effect. |
