Cardioprotective Effect of Spinosin against Doxorubicin Induced Inflammatory and Hypertrophy via Nrf2 Signaling

Pathological cardiac remodeling can lead to heart failure and cardiac hypertrophy. Zizyphus jujuba var spinosa seeds contain SPN, a C-glycoside flavonoid used in traditional medicine. A growing body of evidence indicates they have pharmacological potential against a wide range of diseases. Spinosin (SPN), however, has not been examined in relation to doxorubicin (Dox) induced cardiac injuries. To find out if SPN can reverse Dox-induced cardiomyopathies, we conducted this study. Results showed that Dox treatment led to bigger cardiomyocytes, more inflammatory markers, and more cytokines. SPN treatment, however, reduced Dox-induced enlargement, attenuated hypertrophic markers, and attenuated the expression of inflammatory markers. Moreover, we saw increased levels of oxidative stress-related proteins NRF2, HO-1, and NQO-1. SPN protects against oxidative stress and inflammation-induced cardiomyopathies, according to our study.
