Genome-Wide Assessment of AU-Rich Elements by the AREScore Algorithm [PDF]
, 2012 In mammalian cells, AU-rich elements (AREs) are well known regulatory sequences located in the 3' untranslated region (UTR) of many short-lived mRNAs. AREs cause mRNAs to be degraded rapidly and thereby suppress gene expression at the posttranscriptional

Kaposin-B enhances the PROX1 mRNA stability during lymphatic reprogramming of vascular endothelial cells by Kaposi's sarcoma herpes virus. [PDF]
, 2010 Kaposi's sarcoma (KS) is the most common cancer among HIV-positive patients. Histogenetic origin of KS has long been elusive due to a mixed expression of both blood and lymphatic endothelial markers in KS tumor cells.

Novel endoribonucleases as central players in various pathways of eukaryotic RNA metabolism [PDF]
, 2010 For a long time it has been assumed that the decay of RNA in eukaryotes is mainly carried out by exoribonucleases, which is in contrast to bacteria, where endoribonucleases are well documented to initiate RNA degradation.

In vivo Imaging of oskar mRNA transport reveals the mechanism of posterior localization [PDF]
, 2008 oskar mRNA localization to the posterior of the Drosophila oocyte defines where the abdomen and germ cells form in the embryo. Although this localization requires microtubules and the plus end-directed motor, kinesin, its mechanism is controversial and ...

Regulation of mRNA stability via BRF1 and other AU-binding proteins [PDF]
, 2005 Steady state levels of mRNAs are determined by the rate of synthesis and degradation. A well-known cis-element conferring instability to mRNA is the so-called AU-rich element (ARE), which is present in the 3’ untranslated region (3’UTR) of many cytokines,

Regulation of processing body formation in the budding yeast "Saccharomyces cerevisiae" [PDF]
, 2014 The life cycle of mRNA, from transcription to decay, is a tightly regulated biological process. mRNA is an essential molecule that the cell utilizes to alter gene expression. Degradation is one process through which the cell can regulate mRNA levels.

FEBS Letters, EarlyView.How do genomes gain new functional parts? In eukaryotes, which tend to evolve under weak selection, much of the genome is junk. Palazzo and Qiu borrow the logic of Markov chains to show how non‐functional DNA becomes functional through the appearance of intermediate states, which arise due to epistasis, buffering, and biochemical messiness, allowing ...

Membrane composition and thermodynamic identity as boundaries of life for synthetic cell research
FEBS Letters, EarlyView.What makes a cell a cell? The boundary of a living cell is not just a wall. Read as a Markov blanket, the membrane separates internal from external states, generating identity and non‐equilibrium order. Can this identity be rebuilt from scratch in a synthetic cell?

Molecular Oncology, EarlyView.We identify USP29 as the only DUB mirroring CA9 expression, a marker of hypoxia and HIF pathway activation associated with PCA aggressiveness. USP29 stabilizes HIF‐1α and HIF‐2α via a noncanonical mechanism that is independent of PHD/pVHL activity yet relies on proteasomal regulation, establishing USP29 as a previously unrecognized regulator of hypoxic
