In natural environments, photosynthetic organisms adjust their metabolism to cope with the fluctuating availability of combined nitrogen sources, a growth-limiting factor. For acclimation, the dynamic degradation/synthesis of tetrapyrrolic pigments, as well as of the amino acid arginine, is ...
Pancreatic cancer is an aggressive cancer with a poor prognosis. Metabolic abnormalities are one of the hallmarks of pancreatic cancer, and pancreatic cancer cells can adapt to biosynthesis, energy intake and redox needs through metabolic reprogramming to tolerate nutrient deficiency and hypoxic ...
BACKGROUND: Myocardial infarction (MI), one of the leading causes of mortality worldwide, remains a clinical challenge due to limitations in current therapeutic strategies. The cardiac vascular network, as the fundamental architecture sustaining myocardial function, delivers oxygen and nutrients ...
