Fig. 8. Mode of action of Calderón. Proposed model illustrating the
role of cald in Drosophila growth. Genetic and/or
biochemical relationships are depicted as arrows to indicate positive
regulators or as bars to represent negative regulators of targets. The TOR and
InR pathways integrate the nutritional information and exert a control on cell
growth, in part, regulating cald expression. Cald activity is
required for the control of growth: cell size and proliferation.
