Coenzyme Q10, one of the best-selling nutrient supplements to support heart health also could be beneficial for kidney health, according to research conducted in transgenic fruit flies that was led by Zhe Han, Ph.D., associate professor at Children’s Center for Cancer and Immunology Research.
Nephrocytes, filtration kidney cells in Drosophila, require the Coq2 gene for protein reabsorption, toxin sequestration and critical cell ultrastructure. Silencing the Coq2 gene results in aberrantly localized nephrocyte slit diaphragms and deformed lacunar channels, Han and co-authors found. Nephrocytes closely resemble the podocytes of the human kidney.
“I am honored that the JASN editors chose to feature my lab’s work on the cover of this prestigious journal,” Han says. “This underscores the utility of our gene-replacement approach, which silenced the fly homolog in the tissue of interest – here, the kidney cells – and provided a human gene to supply the silenced function.”
