DRiPs and mCherry-VHL convert PML-NBs into an amyloid solid-like state that chaperones can revert (see also -9).Figure 6PML-GFP HeLa Kyoto cells were lipofected with a cDNA encoding for mCherry-VHL. 24 h post-transfection, cells were left untreated or treated with MG132 (10 µM) and OP-puro (25 µM) for 4 h. Where indicated (OP-puro + MG132 + CHX), translation was inhibited during stress with cycloheximide (CHX; 50 μg/ml).

Figure 7(A) In wild type situation, yki alternative splicing allows production of a major fully active isoform Yki2, and a minor isoform Yki1 with reduced activity. This equilibrium contributes to developmental stability. (B) B52 depletion reduces yki exon3 inclusion level and therefore lowers Yki2/Yki1 ratio. The increased amount of Yki1 enhances its competition with Yki2 for binding to Sd, leading to a decrease of Yki target genes transcription. B52 depletion leads to reduced growth and increased developmental instability. (C) In yki2-only flies, absence of yki alternative splicing causes unbalanced expression of Yki2 isoform which leads to premature pupariation and to increased developmental instability.
