Fig. 5. Regulation of germ cell cycle during dauer development. Under
reduced daf-2/insulin-like receptor and/or daf-7/TGF-ß
activity, daf-18/PTEN, par-4/LKB1 and
aak-1,aak-2/AMPK mediate the downregulation of germline proliferation
during dauer development. Although the role of par-4 in
aak-1 activity is obvious, the relationship between daf-18,
par-4 and aak-2 remains unclear. Arrows and bars represent
positive and negative genetic interactions, respectively.
