"we were able to recover HSP-90 but not HSP-70 with both CED-4::GFP and CED-3::GFP, but not from worms expressing GFP alone. Crucially, we found that the levels of HSP-90 recovered with CED-3::GFP, but not CED-4::GFP, increased in response to
mtch-1(RNAi), suggesting that HSP-90 is re-directed away from existing HSF-1-repressing complexes and toward CED-3 upon loss of MTCH-1."
