TL;DR: It is shown that let-7 is a heterochronic switch gene that encodes a temporally regulated 21-nucleotide RNA that is complementary to elements in the 3′ untranslated regions of the heteroch chronic genes lin-14, lin-28, Lin-41, lin -42 and daf-12, indicating that expression of these genes may be directly controlled by let- 7.

TL;DR: It is shown that a promoter-associated RNA polymerase II molecule is transcriptionally engaged and has formed a nascent RNA chain, but is apparently arrested at that point and unable to penetrate further into the hsp70 gene without heat induction.

TL;DR: Examination of the hb 3'UTR reveals potential binding sites for known fly miRNAs and finds that hbl-1/lin-57 is regulated by let-7, at least in the nervous system, which suggests evolutionary conservation of hunchback genes may include temporal control of cell fate specification and microRNA-mediated regulation.

TL;DR: Findings indicate that quiescence of germline development during L1 diapause is not a passive consequence of nutrient deprivation, but rather is actively maintained by DAF-18 through a pathway distinct from that which regulates longevity and dauer formation.

TL;DR: The Caenorhabditis elegans heterochronic genes control the relative timing and sequence of many events during postembryonic development, including the terminal differentiation of the lateral hypodermis, which occurs during the final (fourth) molt, and lin-42 most closely resembles the Period family of proteins from Drosophila and other organisms.
