On the cover: Overexpression of transcription factor SAF-1 in synoviocyte cells results in cell growth inhibition. Cell growth was monitored by following the expression of green fluorescence protein (GFP). Cells were transiently transfected with either control (upper panels, 24 and 72 h) or SAF-1 expressing plasmid (lower panels, 24 and 72 h). Ray et al.
