We used RNAase protection and restriction fragment length polymorphism assays to detect activating mutations of c-src in a spectrum of human tumours. No mutations were detected at codons 98, 381, 444, and 530. We conclude that mutational activation is not the mechanism of enhancement of pp60c-src-specific kinase activity found in a number of human cancer types.

Hepatocellular carcinoma (HCC) is the most common type of liver solid tumor and the second leading cause of cancer-related deaths worldwide. Although new treatment options have been recently approved, the development of tumor resistance and the poor prognosis for advanced HCC make the current standard of care unsatisfying. In this scenario, the non-receptor tyrosine kinase (TK) c-Src emerged as a promising target for developing new anti-HCC agents.

Vascular retinopathy, characterized by abnormal blood vessel growth in the retina, frequently results in vision impairment or loss. Neovascular tufts, a distinctive pathologic feature of this condition, are highly leaky blood vessel structures, exacerbating secondary complications. Despite their clinical significance, the mechanisms underlying tuft development are not fully elucidated, posing challenges for effective management and treatment of vascular retinopathy.

Acacetin (ACA) and biochanin A (BCA) are isomeric monomethoxyflavones with different structural positions of the 4'-methoxy-phenyl group. Both of them are present in many commonly consumed foods, such as citrus fruits and vegetables, and have been discovered with anti-inflammatory activities, but their mechanisms of action are not clearly elucidated at the molecular level. Herein, we reported the structure-activity relationship of ACA and BCA regarding their potency in inhibiting nitric oxide (NO) production, proinflammatory enzyme expression, and mRNA expression of proinflammatory cytokines in the lipopolysaccharide (LPS)-induced RAW 264.
