doi: 10.3390/cells10040777

Figure Lengend Snippet: High phosphate exacerbates atg5 deficiency-induced cardiac remodeling. High phosphate decreases autophagy activity in cardiomyocytes. Atg5 deletion in cardiomyocytes downregulates autophagy activity in cardiomyocytes. Low autophagy activity results in cardiomyocyte apoptosis. High phosphate also induces cardiomyocyte apoptosis, which is autophagy-independent. Increase in apoptosis in cardiomyocytes leads to cardiomyocyte damage and cardiac hypertrophy and fibrosis. Therefore, high phosphate and low autophagy individually trigger and additionally promote heart deterioration. However, high-phosphate-induced pathologic cardiac remodeling might be autophagy-independent and apoptosis-independent (dash line), whose mechanisms are not explored in the current study. On the other hand, low autophagy can induce cardiac remodeling independently of apoptosis (dash line), which is worth illustrating.
