Using a genome-wide CRISPR screen comparing low- and high-density parasite growth, the team found TgPRO stabilizes RNAs involved in mitochondrial activity, nutrient use, and iron-sulfur cluster assembly. Mice infected with TgPRO-deficient parasites developed smaller brain cysts, and lowering oxygen levels partially restored growth in TgPRO-lacking parasites, revealing lab oxygen levels may not reflect tissue conditions. The findings represent the first dedicated regulator of metabolic gene expression identified in apicomplexan parasites and suggest inhibiting TgPRO pathways could be a future therapeutic angle to sensitize Toxoplasma to oxidative-stress-inducing drugs. ## Full article daily.dev links to this article rather than hosting it.
