Knocking out histidine ammonia-lyase by using CRISPR-Cas9 abolishes histidine role in the bioenergetics and the life cycle of Trypanosoma cruzi

Janaína de Freitas Nascimento1, María Julia Barisón1, Gabriela Torres Montanaro1, Letícia Marchese1, Rodolpho Ornitz Oliveira Souza1, Letícia Sophia Silva2, Alessandra Aparecida Guarnieri2 and Ariel Mariano Silber1

Recent studies have highlighted the importance of this pathway in ATP production, redox balance, and the maintenance of cellular homeostasis in T. cruzi. In this work, we focus on the first step of the histidine degradation pathway, which is performed by the enzyme histidine ammonia lyase. Here we determined the kinetic and biochemical parameters of the T. cruzi histidine ammonia-lyase.

Dissecting the cell cycle regulation, DNA damage sensitivity and lifespan effects of caffeine in fission yeast

John-Patrick Alao1, Juhi Kumar1, Despina Stamataki2 and Charalampos Rallis1

Our findings show that caffeine accelerates mitotic division and is beneficial for CLS through AMPK. Direct pharmacological targeting of AMPK may serve towards healthspan and lifespan benefits beyond yeasts, given the highly conserved nature of this key regulatory cellular energy sensor.
