Terminally differentiated neurons and glia can re-enter the cell cycle to become polyploid in the adult fly brain, to protect cells from DNA damage-associated death.
Genetic analyses illustrate the novel requirement of Ftz-f1 and Sim in adult Drosophila ovaries for regulating follicle cell differentiation and ovulation that is likely conserved in mammals.
Morphological and functional rejuvenation upon exit from adult reproductive diapause in C. elegans is independent of germline signaling, but instead involves somatic nucleolar activation and expansion of the RNA pool.
Hindsight/RREB-1 plays a conserved role in follicle maturation and ovulation by sequential upregulation of matrix metalloproteinase and adrenergic receptor in follicle cells.
SUMO-dependent pathway is responsible for selective repression of damaged rDNA and silencing of intact surplus units revealing an epigenetic mechanism that controls the differential expression of identical sequences in the same cell.
The immune effector Drosomycin buffers stress signaling in hypertrophic salivary glands to inhibit their disintegration, detection by the cellular immune response, and promotes further overgrowth.
