Centranthera grandiflore alleviates alcohol-induced oxidative stress and cell apoptosis.

Alcohol liver disease (ALD) has become a global threat to human health. It is associated with a wide range of liver diseases including alcohol fatty liver, steatosis, fibrosis and cirrhosis, and finally leads to liver cancer and even death. Centranthera grandiflora is a traditional Chinese medicinal herb commonly used to treat ALD, but no research about its mechanism is available. This study evaluated the hepatoprotective effect and mechanism of C. grandiflora against alcohol-induced liver injury in mice. We found that the ethanol extracts of C. grandiflora (CgW) alleviated the alcohol-induced liver injury, enhanced the levels of antioxidant enzymes, and reduced the amount of lipid peroxides. CgW also affected cell apoptosis by inhibiting the activity of Bax, cleaved-caspase 3 and cleaved-caspase 9, and increasing the activity of Bcl-2. In conclusion, the results showed that CgW can effectively improve ALD through alleviating oxidative stress and inhibiting cell apoptosis for the first time. This study suggested that C. grandiflora is a promising herbal medicine for ALD treatment.

Integrins as attractive targets for cancer therapeutics

Integrins are transmembrane receptors that have been implicated in the biology of various human physiological and pathological processes. These molecules facilitate cell-extracellular matrix and cell-cell interactions, and they have been implicated in fibrosis, inflammation, thrombosis, and tumor metastasis. The role of integrins in tumor progression makes them promising targets for cancer treatment, and certain integrin antagonists, such as antibodies and synthetic peptides, have been effectively utilized in the clinic for cancer therapy. Here, we discuss the evidence and knowledge on the contribution of integrins to cancer biology. Furthermore, we summarize the clinical attempts targeting this family in anti-cancer therapy development.
