"
bar-1(RNAi) embryos do not display defects in mgPOP-1 asymmetry and with the report that a putative
bar-1 null mutant does not display defects in MS specification (Table 1; Eisenmann et al., 1998)... As seen with immunostaining of endogenous POP-1, b-catenin/WRM-1 and other Wnt/MAPK components are required for this asymmetry in nuclear mgPOP-1 levels (Fig. 3D and Table 1; Thorpe et al., 1997; Rocheleau et al., 1997; Lin et al., 1998)."
