Young nematodes exposed to MnCl2 for 30 min show a 3-fold increase in GST-1 mRNA levels. Exposure to Mn results in a 3-4-fold increase in GST-1 protein levels.
Young nematodes exposed to 100 M AlCl<sub>3</sub> for 30 min showed a dramatic decrease in SMF-3 protein levels within 24 h. These results indicate that SMF-3 protein levels are exquisitely sensitive to Al<sup>3+</sup>.
In wild-type, GFP:MEI-1 levels remain steady for w25 30 min after egg exit from the spermatheca. In contrast, in egg-3(tm1191) mutants, GFP:MEI-1 levels started to decline immediately after spermatheca exit, reaching background levels by 30 min.
