The subcellular distribution of zinc in dog prostate studied by x-ray microanalysis

Cell and Tissue Research
J A ChandlerC G Pierrepoint


X-ray microanalysis of zinc in ultrathin sections of dog prostate was performed by electron microscope microanalysis using the potassium pyroantimonate method of preparation. Prostates of both mature and immature dogs were examined and the metal was found to be localised primarily in the nucleolus, nuclear chromatin and secretory granules of epithelial cells. Differences in zinc concentrations were observed between mature and immature tissues, particularly in the nuclear chromatin. The metal was also incorporated into epithelial secretions, lysosomes and fibromuscular stroma. Variable binding of zinc to tissue components was revealed by a combination of histochemical precipitation and subcellular analysis.

Coronaviruses encompass a large family of viruses that cause the common cold as well as more serious diseases, such as the ongoing outbreak of coronavirus disease 2019 (COVID-19; formally known as 2019-nCoV). Coronaviruses can spread from animals to humans; symptoms include fever, cough, shortness of breath, and breathing difficulties; in more severe cases, infection can lead to death. This feed covers recent research on COVID-19.

Genetic Screens in iPSC-derived Brain Cells

Genetic screening is a critical tool that can be employed to define and understand gene function and interaction. This feed focuses on genetic screens conducted using induced pluripotent stem cell (iPSC)-derived brain cells. It also follows CRISPR-Cas9 approaches to generating genetic mutants as a means of understanding the effect of genetics on phenotype.
