WebApr 11, 2024 · The crosstalk and feedback within the heterochronic pathway is remarkable. A recent example of this is the demonstration that lin-4 both directly represses and indirectly promotes lin-28 expression, and that the indirect action is via repression of the let-7 sisters by LIN-14 (another lin-4 target) [63]. Technological advances will certainly ... WebThis suggests that lin-4 down-regulates lin-14 transla- tion by forming multiple RNA duplexes with the lin-14 mRNA (Wightman et al. 1993). Here we show that multiple elements in the lin-14 3' UTR are conserved between C. briggsae and C. elegans, but that the lin-4 complementary elements account for
