The results showed that Biochanin A inhibited cell proliferation, increased reactive oxygen species formation, and induced apoptosis. Furthermore, western blot analysis revealed that Biochanin A-treated cells exhibited lower expression of the Bcl-2, p-PI3K and p-AKT and higher expression of proapoptotic genes, including Bax, Caspase-3, Caspase-9, and cytochrome c. Additionally, PCR array analysis indicated that the gene expression levels of cyclin D3, cyclin B1, CDK1, CDK2, and CDK4 were downregulated, while the expression levels of p21, p27, and p53 were significantly upregulated.

In the recent decade, targeting tumor stroma consisting of extracellular matrix (ECM), immune cells, vascular system, hypoxia, and also suppressive mechanisms in HCC has attracted interest in repressing tumor growth and metastasis. Phytochemicals have attained considerable attention because of their manifold biological effects and high capacity for anticancer activities. These chemical agents have shown the capability to modulate different cells and secretions within the stroma of malignancies. In recent years, the development of nanoformulations has further enhanced the therapeutic potential of phytochemicals by improving their solubility, bioavailability, and targeted delivery to tumor tissues. This review aims to provide an encyclopedic overview of the potential of phytochemicals and their nanoformulations as promising therapeutic strategies for targeting HCC. The review initially highlights the broad array of phytochemicals exhibiting potent anticancer properties, including flavonoids, alkaloids, terpenoids, and phenolic compounds, among others. Then, the nanoformulations and modification of these agents will be reviewed. Finally, we will review the latest experiments that have examined the modulation of HCC using adjuvant phytochemicals and their nanoformulations.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 8","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142615662","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Apigenin (4′,5,7-trihydroxyflavone) is a natural flavonoid that exhibits antioxidant, anti-inflammatory and anticancer effects. The present study aims to investigate the effect of apigenin on perimenopausal syndrome by combining bioinformatics analysis with in vivo experiments. The mouse model with perimenopausal syndrome was established using 4-vinylcyclohexene diepoxide (VCD) treatment. Apigenin alleviated VCD-induced disorder of estrous cycle and shrinkage of ovarian tissue. The reduction of anti-Muller hormone and the increase of follicle stimulation hormone and luteinizing hormone triggered by VCD were reversed by apigenin in a dose-dependent manner. Apigenin suppressed the VCD-induced decrease of primordial, primary, secondary and antral follicle number in ovarian tissue. Oxidative stress in ovarian tissue was activated by VCD treatment through increasing the reactive oxygen species production. High concentration of apigenin significantly reversed the alteration induced by VCD. Apigenin alleviated VCD-induced cell apoptosis through regulating Bax, Bcl-2, cleaved PARP1 and caspase-3. Furthermore, the phosphorylation of AKT and FOXO3a was inhibited by VCD and activated by apigenin in a dose-dependent manner.

This study investigates the protective effect of Biochanin A (BCA) against gamma radiation-induced oxidative stress and DNA damage in Swiss albino mice. Gamma radiation, a potent ionizing source, generates reactive oxygen species (ROS) that damage cellular biomolecules, including DNA. Antioxidants play a crucial role in neutralizing ROS and preventing oxidative damage. Swiss albino mice were divided into control, BCA control (10 mg/kg body weight), radiation alone (7 Gy), and radiation+ BCA pretreatment groups. BCA, a natural isoflavone with known antioxidant and cytoprotective properties, was administered intraperitoneally before radiation exposure. After irradiation, lipid peroxidation levels, antioxidant enzyme activities/level (superoxide dismutase, catalase, glutathione peroxidase and reduced glutathione), expression levels of DNA repair genes (P53, P21, GADD45α), apoptotic markers (Bax, Bcl-2, Caspase-3, -9 and Cytochrome-C), and inflammatory marker (NF-κB) were analyzed in small intestine tissue. Our findings indicate that gamma radiation significantly elevated lipid peroxidation levels and altered antioxidant enzyme activities, indicating oxidative stress. However, BCA pretreatment mitigated these effects by bolstering antioxidant defences, reducing radiation-induced oxidative damage. Additionally, BCA altered apoptotic markers, NF-κB expression, promoting cell survival mechanisms. At the molecular level, BCA pretreatment upregulated key DNA repair genes (P53, P21, GADD45α), crucial for repairing radiation-induced DNA damage and maintaining genomic stability. These results underscore BCA potential as a radioprotector, suggesting its efficacy in mitigating radiation-induced oxidative stress and preserving cellular integrity. In conclusion, BCA demonstrates promising radioprotective properties by attenuating oxidative stress, enhancing antioxidant defences, modulating apoptotic pathways, and promoting DNA repair mechanisms following gamma radiation exposure. Further research is necessary to elucidate its precise mechanisms of action and explore its potential therapeutic applications in radiation oncology and environmental radioprotection.</p></div>","PeriodicalId":9669,"journal":{"name":"Cell Biochemistry and Function","volume":"42 8","pages":""},"PeriodicalIF":2.8,"publicationDate":"2024-11-05","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142582144","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"生物学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
