- Activation-induced cell death of T lymphocytes requires the inducible expression of CD95 (APO-1/Fas) ligand, which triggers apoptosis in CD95-bearing target cells by an autocrine or paracrine mechanism. Although execution of the CD95 death pathway is largely independent of reactive oxygen intermediates, activation-induced cell death is blocked by a variety of antioxidants. In the present study, we investigated the involvement of redox processes in the regulation of CD95 ligand (CD95L) expression in Jurkat T cells. We show that various antioxidants potently inhibited the transcriptional activation of CD95L following T cell receptor litigation or stimulation of cells with phorbol ester and ionomycin. Conversely, a prooxidant such as hydrogen peroxide alone was able to increase CD95L expression. As detected by Western blot and cytotoxicity assays, functional expression of CD95L protein was likewise diminished by antioxidants. Inhibition of CD95L expression was associated with a decreased DNA binding activity of nuclear factor (NF)-kappa B, an important redox-controlled transcription factor. Moreover, inhibition of NF-kappa B activity by a transdominant I kappa B mutant attenuated CD95L expression. Our data suggest that, although reactive oxygen intermediates do not act as mediators in the execution phase of CD95-mediated apoptosis, they are involved in the transcriptional regulation of CD95L expression.

Role of ICE-related and other proteases in Fas-mediated apoptosis

Forskningsöversikt (refereegranskat)abstract
- Interleukin-1 beta-converting enzyme (ICE)-like proteases comprise a novel family of unusual cysteine proteases which have been implicated in programmed cell death in both invertebrates and mammals. Current available evidence indicates a role of ICE proteases as central executioners of apoptosis triggered by the cell surface receptor Fas (APO-1). The presence of multiple mammalian ICE proteases with partially overlapping but distinct activities suggests a complex proteolytic cascade which is induced upon Fas ligation. The precise role of single members of the ICE family in Fas-mediated apoptosis, however, is still unclear. Here, we summarize the present knowledge about the relevance of ICE proteases, their potential targets, and interaction with unrelated proteases in cell death mediated by Fas and other apoptotic stimuli.

- The Eurobarometer on Biotechnology (46.1) was conducted during October and November 1996. The survey conducted in each EU (European Union) country used a multi-stage random sampling procedure and provided a statistically representative sample of national residents aged 15 and over. The total sample within the EU was 16,246 respondents (about 1,000 per EU country). The survey questionnaire was designed by the authors as part of a larger study involving the comparative analysis of public perceptions, media coverage and public policy in relation to biotechnology from 1973 to the present.

Phenotype in a Swedish family with X-linked retinitis pigmentosa caused by a novel splice defect in the RPGR gene

- PURPOSE: To assess the clinical phenotype in a Swedish family with X- linked retinitis pigmentosa (XLRP) resulting from a novel splice defect in the RPGR gene. METHODS: RPGR mutation analysis was performed in one family with XLRP, and several individuals from the family were examined clinically. RESULTS: The causative mutation in the family was demonstrated to be a single base-pair change at the splice donor site in intron 7 that resulted in skipping of the complete exon 7 in the mature RPGR transcript. The aberrant mRNA is predicted to produce an RPGR protein with an in-frame deletion of 53 amino acids, corresponding to an RCC1-homology repeat. Clinical studies that included ophthalmological examination and full-field electroretinography showed that this splice mutation resulted in a comparatively less severe form of RP. CONCLUSIONS: Correlation of a causative RPGR genotype with clinical findings in hemizygotes and carrier heterozygotes is an important step toward predictive diagnosis and should assist in the development of gene-based therapies in the future.
