"YFP reporters for three collagen genes that normally show peak expression in the L4 stage,
col-38,
col-49, and
bli-1, were crossed into hs::DNTbar-1, hs::DNTpop-1 and hs:: control backgrounds and analyzed for changes in expression after heat shock. For all three col gene reporters, we observed an increase in the percentage of animals showing YFP expression in the L3 stage following heat shock expression of DNTBAR-1 at the L2/L3 molt, and a decrease in the percentage of animals showing YFP expression at all stages following heat shock expression of dominant negative DNTPOP-1 (Table 2)."
