The relative transcript levels of che-1 was significantly (P < 0.01) decreased in animals exposed to MC-LR (10 g/L), suggesting that the specification of ASE and AWA sensory identities were largely disrupted in MC-LR (10 g/L) exposed animals.
The relative transcript levels of odr-7 was significantly (P < 0.01) decreased in animals exposed to MC-LR (10 g/L), suggesting that the specification of ASE and AWA sensory identities were largely disrupted in MC-LR (10 g/L) exposed animals.
Compared with control, the expression levels of exp-1 gene decreased significantly in nematodes exposed to more than 0.1 microgram/l of MC-LR (p<0.001).
The noticed decrease of the expression levels of unc-46 gene was shown after exposure to MC-LR at the concentration at 1 g/l (p<0.01) and 10-100 g/l (p<0.001).
