Mosaic activation of the zebrafish hsp70l heat shock promoter: Implications for interpreting transgenes

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background The promoters and enhancers of heat shock genes, such as the 1.5‐kb promoter of the zebrafish hsp70l gene, are valuable tools for temporal activation of transgenes. It has been widely purported that heat shock treatments result in ubiquitous expression of hsp70l‐driven transgenes.

Vimentin downregulation is an inherent feature of murine erythropoiesis and occurs independently of lineage [PDF]

open access: yes, 1990
In mammalian erythropoiesis, the mature cells of the primitive lineage remain nucleated while those of the definitive lineage are anuclear. One of the molecular and structural changes that precedes enucleation in cells of the definitive lineage is the ...

Development of a Zebrafish Embryo‐Based Test System for Thyroid Hormone System Disruption: 3Rs in Ecotoxicological Research

open access: yesEnvironmental Toxicology and Chemistry, EarlyView.
Abstract There is increasing concern regarding pollutants disrupting the vertebrate thyroid hormone (TH) system, which is crucial for development. Thus, identification of TH system–disrupting chemicals (THSDCs) is an important requirement in the Organisation for Economic Co‐operation and Development (OECD) testing framework.

RBFOX1 Dysfunction Unlocks APOE4‐Associated Microglial Genesis and Exacerbates Alzheimer's Pathology in Human Cerebral Organoids

open access: yesExploration, EarlyView.
Genomic studies implicate RBFOX1 in Alzheimer's disease (AD) risk, highlighting the need to define its role and interactions with other risk factors. Here, CRISPR/Cas9‐mediated RBFOX1 loss in APOE4 human cerebral organoids induces autonomous microglial genesis and accelerates AD pathology, revealing a protective role of RBFOX1 and establishing a model ...
