Argininosuccinate Synthetase 1 deficiency induces dependence on extracellular arginine for continued cellular growth and survival. Arginine starvation inhibits the Warburg effect and diverts glucose into serine biosynthesis, while simultaneously increasing glutamine metabolism via the tricarboxylic acid cycle. Simultaneous arginine deprivation and inhibition of the subsequent metabolic adaptations induce synthetic lethality.
精氨琥珀酸合成酶1缺乏会导致细胞持续生长和存活依赖细胞外精氨酸。精氨酸饥饿会抑制瓦伯格效应,并将葡萄糖转向丝氨酸生物合成,同时通过三羧酸循环增加谷氨酰胺代谢。同时剥夺精氨酸并抑制随后的代谢适应会诱导合成致死。
