From mice to humans—divergent strategies for intestinal homeostasis and regeneration
FEBS Letters, EarlyView.Recent advances such as organoid genome editing, xenotransplantation, imaging, and whole‐genome sequencing have enabled direct studies of human intestinal stem cells (ISCs). These studies reveal species‐specific features, including slower ISC proliferation, distinct injury responses, slower somatic mutation accumulation in humans, and an inverse ...

Cancer Biology & Therapy, 2004 The BRCA1 tumor suppressor gene is expressed in all mammalian cells. Within these cells, the BRCA1 protein product interacts with several seemingly distinct nuclear complexes. Proteins within these complexes are potential targets for the E3-ubiquitin ligase activity associated with BRCA1:BARD1 complexes.

Metabolic control through the PGC-1 family of transcription coactivators [PDF]
, 2005 Many complex biological programs are controlled at the level of gene transcription by DNA binding transcription factors. Recent studies have revealed a novel mode of regulation by coactivator proteins, best illustrated by the PGC-1 family of coactivators.

Phosphoinositides and inositol phosphates as molecular glues
FEBS Letters, EarlyView.Inositol phosphates (IPs) and phosphoinositides (PIPs) regulate diverse eukaryotic processes. Beyond recruiting signaling proteins or acting as structural cofactors, recent studies suggest they mediate protein–protein interactions as natural molecular glues.

Challenges of Decoding Transcription Factor Dynamics in Terms of Gene Regulation
Cells, 2018 Technological advances are continually improving our ability to obtain more accurate views about the inner workings of biological systems. One such rapidly evolving area is single cell biology, and in particular gene expression and its regulation by ...

FEBS Letters, EarlyView.Drosophila park mutants serve as a model for Parkinson's disease. We used this strain to investigate the connection between oxidative stress and the circadian clock mechanism. We showed that increased oxidative stress affects the physiology of pacemaker cells, disrupting their daily structural plasticity. Lack of rhythmic signaling from pacemaker cells

Structural insights and therapeutic targets in Acinetobacter baumannii capsule biosynthesis
FEBS Letters, EarlyView.Hypervirulent KL49 A. baumannii's capsular polysaccharide contains the nonulosonic acid 8‐epi‐Leg5,7Ac2, synthesized by epimerization via ElaA, ElaB, and ElaC. Crystal structures of ElaA, ElaB, and ElaC reveal their role in CMP‐Leg5,7Ac2 synthesis and regioselective C8 epimerization.

Transcript versus transcription?
Epigenetics, 2008 Numerous sense-antisense gene pairs have been discovered in various organisms. Antisense genes play important roles in establishing parentally imprinted gene expression patterns in mammals. Typically, protein-coding sense genes are reciprocally regulated by their non-coding antisense partners.

Maf1-mediated repression of RNA polymerase III transcription inhibits tRNA degradation via RTD pathway [PDF]
, 2012 tRNA precursors, which are transcribed by RNA polymerase III, undergo end-maturation, splicing and base modifications. Hypomodified tRNAs, such as tRNAVal(AAC), lacking 7-methylguanosine and 5-methylcytidine modifications, are subject to degradation by a
