Stern et al. found in multiple cancer cell lines that a TERT gene with a promoter mutation exhibits the H3K4me2/3 mark of active chromatin, while the wild-type allele retains the H3K27me3 mark of epigenetic silencing.

Phosphoinositides and inositol phosphates as molecular glues
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.

Passing the baton: The HIF switch
Hypoxia is an inadequate oxygen supply to tissues and cells, which can restrict their function. The hypoxic response is primarily mediated by the hypoxia-inducible transcription factors, HIF-1 and HIF-2, which have both overlapping and unique target ...

Inositol pyrophosphates are energy‐rich signaling molecules that perform critical functions in cells. Three different families of phosphatases hydrolyze the β phosphate of the inositol pyrophosphate molecules: two have narrow specificities and one is promiscuous.

Identification and characterisation of behavioural genes of agrobacterium tumefaciens. [PDF]
Three behavioural mutants (fla-8, mot-6 and cheL) generated by transposon Tn5 mutagenesis and localised on cosmid pDUB1905 were studied. The cosmid pDUB1905, from a representative genomic library of the Agrobacterium tumefaciens C58C1 chromosome has ...

A portable epigenetic switch for bistable gene expression in bacteria
We describe a portable epigenetic switch based on opvAB, a Salmonella enterica operon that undergoes bistable expression under DNA methylation control.

Gene switching at Xenopus laevis metamorphosis
During the climax of amphibian metamorphosis many tadpole organs remodel. The different remodeling strategies are controlled by thyroid hormone (TH). The liver, skin, and tail fibroblasts shut off tadpole genes and activate frog genes in the same cell without DNA replication. We refer to this as "gene switching".

Modelling stem cell differentiation related processes—A practical overview for biologists
Stem cell differentiation is complex and difficult to control experimentally. This review introduces suitable computational modelling approaches that can support stem cell research, from mechanistic ODE and abstract models to multiscale and deep learning methods.

Identification and characterization of TNFalpha responsive genes in human breast cancer cells
One of the hallmarks of cancer is the escape of the transformed cells from apoptosis. Therefore, the identification of survival genes, allowing cancer cells to circumvent programmed cell death, could provide new diagnostic markers as well as targets for ...

Histone acetylation and globin gene switching
An affinity-purified antibody that recognises the epitope epsilon-acetyl lysine has been used to fractionate chicken erythrocyte mononucleosomes obtained from 5 and 15 day embryos. The antibody bound chromatin was enriched in multiply acetylated forms of the core histones H3, H4 and H2B, but not in ubiquitinated H2A.
