A genetic screen and combined bioinformatic analyses revealed multiple novel transcription factors and their hierarchical organization in coordinating mitochondrial biogenesis.
An enhancer-dependent transcriptional machinery finely tunes the expression of Ctnnb1 in intestinal crypts, thereby balancing homeostasis and tumorigenesis of intestinal epithelia.
PITAR interaction with TRIM28 mRNA, which encodes a p53 targeting E3 ubiquitin ligase, keeps p53 levels low for cancer cells to divide and attenuates the DNA damage response by p53.

The genetic 'fossil record' of a retroviral lineage over >25 million years of evolution reveals the profound consequences of an ancient recombination event on viral replication mechanisms and genome structure, and identifies an ancient interspecies viral transmission.
A genetic variant within a newly identified enhancer regulates the expression of a key pharmacogene and alters the balance between resistance and sensitivity to a widely used chemotherapeutic.
