Biochem/physiol Actions

4-Hydroxytamoxifen (4-HT) is the active metabolite of tamoxifen which binds estrogen receptors (ER) and estrogen-related receptors (ERR) with estrogenic and anti-estrogenic effects. It is a cell permeable, selective estrogen receptor modulator (SERM). In Cas9 variants engineered with ligand-dependent inteins 4-Hydroxytamoxifen was used control Cas9 function, which reduced off target effects in CRISPR-mediated gene editing.

The bimodal requisite for a genetic program and external stimuli is a key feature of sensory circuit formation. However, the contribution of cell-intrinsic codes to directing sensory-specific circuits remains unknown. Here, we identify the earliest molecular program that preselects projection...

Directly modulating the activity of genome-editing proteins has the potential to increase their specificity by reducing activity following target locus modification. We developed Cas9 nucleases that are activated by the presence of a cell-permeable small molecule by inserting an evolved...

Autophagosomes primarily mediate turnover of cytoplasmic proteins or organelles to provide nutrients and eliminate damaged proteins. In neurons, autophagosomes form in distal axons and are trafficked retrogradely to fuse with lysosomes in the soma. Although defective neuronal autophagy is associated...

The fully developed adult skeleton adapts to mechanical forces by generating more bone, usually at the periosteal surface. Progenitor cells in the periosteum are believed to differentiate into bone-forming osteoblasts that contribute to load-induced adult bone formation, but in vivo evidence...

Hypoxia-inducible factor (HIF), consisting of a labile alpha subunit and a stable beta subunit, is a master regulator of hypoxia-responsive mRNAs. HIF alpha undergoes oxygen-dependent prolyl hydroxylation, which marks it for polyubiquitination by a complex containing the von Hippel-Lindau protein...
