Hernandezine Regulates Proliferation and Autophagy-Induced Apoptosis in Melanoma Cells
J Nat Prod 2022 May 27;85(5):1351-1362.PMID:35544345DOI:10.1021/acs.jnatprod.2c00098.
Hernandezine is isolated from an herbal medicine that selectively inhibits multidrug resistance and improves the efficacy of drugs for cancer treatment. To date, no studies on Hernandezine in melanoma have been conducted. In this study, Hernandezine was found to inhibit proliferation and induce apoptosis in melanoma A375 cells and B16 cells. In hernandezine-treated melanoma cells, G0/G1 cycle arrest occurred accompanied by significantly downregulated levels of phosphorylated JAK2 and STAT3. In addition, the cycle arrest could be enhanced by AG490 (JAK2 inhibitor), suggesting that the JAK2/STAT3 pathway is involved in cell cycle regulation in hernandezine-treated melanoma cells. Hernandezine-treated melanoma cells exhibited autophagy-specific structures, autophagy markers (LC3II/LC3-I), and autophagic flow over time. Moreover, 3-MA (autophagy inhibitor) significantly inhibited apoptosis, indicating that Hernandezine promotes apoptosis by inducing autophagy. Combined with differential expression of P-AMPK, P-ACC (downstream targets of adenine monophosphate activated protein kinase, AMPK), and P-p70S6K (downstream targets of mammalian target of rapamycin, mTOR) and significant inhibition of apoptosis by AMPK inhibitor complex C (CC) in hernandezine-treated melanoma cells suggested that Hernandezine could induce autophagy via the AMPK-mTOR pathway, thereby inducing apoptosis. This study first analyzed the effect of melanoma cells by Hernandezine and provided a theory for Hernandezine in the treatment of melanoma.
Hernandezine, a natural herbal alkaloid, ameliorates type 2 diabetes by activating AMPK in two mouse models
Phytomedicine 2022 Oct;105:154366.PMID:35933900DOI:10.1016/j.phymed.2022.154366.
Background: AMP-activated protein kinase (AMPK) is an effective target for treating diabetes. However, successful drug development is delayed due to issues including toxicity. Plant-derived natural product AMPK activators have emerged as a new way to treat diabetes due to its potential low safety risks. Here, we studied the effect of Hernandezine (HER), a natural product derived from Thalictrum, in activating AMPK and treating T2D in mouse models. Method: We tested HER in various cells and tissues, including primary hepatocytes, skeletal myotubes cell lines, as well as major metabolic tissues from diabetic (db/db) and diet-induced obesity (DIO) model mice. The effect of HER on glucose uptake via AMPK in vitro and in vivo was confirmed utilizing cell transfection and adenovirus interference analysis. Tissue staining assessed the effect of HER on adipogenesis. Real-time quantitative polymerase chain reaction (real-time PCR) was applied to verify the effect of HER on transcription factors. Western blot analysis was used to determine the activation of phosphorylated AMPK and ACC pathways. Results: Biochemically, we found that HER prevented pAMPK from dephosphorylation to prolong its activity, disproving previous direct activation model and providing a new model to explain HER-mediated AMPK activation. HER could be orally delivered to animals and has a 3-fold long half-life in vivo as compared to metformin. Importantly, long-term oral HER treatment potently reduced body weight and blood glucose in both type 2 diabetes mullitus (T2DM) mouse models by increasing glucose disposal and reducing lipogenesis, and appeared not to induce cardiac hypertrophy. Conclusion: Natural product HER indirectly activates AMPK by suppressing its dephosphorylation. Oral HER effectively alleviated hyperglycemia and reduced body weight in T2D mouse models, appeared to have a low risk of causing cardiac hypertrophy, and might be a potential therapeutic option for T2DM.
A novel AMPK activator Hernandezine inhibits LPS-induced TNFα production
Oncotarget 2017 Jun 5;8(40):67218-67226.PMID:28978028DOI:10.18632/oncotarget.18365.
Here, we found that Hernandezine, a novel AMPK activator, inhibited LPS-induced TNFα expression/production in human macrophage cells (THP-1 and U937 lines). Activation of AMPK is required for hernandezine-induced anti-LPS response. AMPKα shRNA or dominant negative mutation (T172A) blocked hernandezine-induced AMPK activation, which almost completely reversed anti-LPS activity by Hernandezine. Exogenous expression of the constitutively activate AMPKα (T172D, caAMPKα) also suppressed TNFα production by LPS. Remarkably, Hernandezine was unable to further inhibit LPS-mediated TNFα production in caAMPKα-expressing cells. Hernandezine inhibited LPS-induced reactive oxygen species (ROS) production and nuclear factor kappa B (NFκB) activation. Treatment of Hernandezine in ex-vivo cultured primary human peripheral blood mononuclear cells (PBMCs) also largely attenuated LPS-induced TNFα production. Together, we conclude that AMPK activation by Hernandezine inhibits LPS-induced TNFα production in macrophages/monocytes.
Hernandezine, a novel AMPK activator induces autophagic cell death in drug-resistant cancers
Oncotarget 2016 Feb 16;7(7):8090-104.PMID:26811496DOI:10.18632/oncotarget.6980.
Drug resistance hinder most cancer chemotherapies and leads to disease recurrence and poor survival of patients. Resistance of cancer cells towards apoptosis is the major cause of these symptomatic behaviours. Here, we showed that isoquinoline alkaloids, including liensinine, isoliensinine, dauricine, cepharanthine and Hernandezine, putatively induce cytotoxicity against a repertoire of cancer cell lines (HeLa, A549, MCF-7, PC3, HepG2, Hep3B and H1299). Proven by the use of apoptosis-resistant cellular models and autophagic assays, such isoquinoline alkaloid-induced cytotoxic effect involves energy- and autophagy-related gene 7 (Atg7)-dependent autophagy that resulted from direct activation of AMP activated protein kinase (AMPK). Hernandezine possess the highest efficacy in provoking such cell death when compared with other examined compounds. We confirmed that isoquinoline alkaloid is structurally varied from the existing direct AMPK activators. In conclusion, isoquinoline alkaloid is a new class of compound that induce autophagic cell death in drug-resistant fibroblasts or cancers by exhibiting its direct activation on AMPK.
Inhibitory Effect of Hernandezine on the Proliferation of Hepatocellular Carcinoma
Biol Pharm Bull 2023;46(2):245-256.PMID:36724952DOI:10.1248/bpb.b22-00612.
Hepatocellular carcinoma (HCC) causes 830000 deaths every year and is becoming the third malignant tumor worldwide. One of the primary reasons is the lack of effective drugs. Hernandezine (HER), a bisbenzylisoquinoline alkaloid of Thalictrum simplex, has been confirmed to have antitumor activity. But there are few reports about its effect on HCC and the underlying mechanisms still remain unclear. Therefore, the antitumor effects and mechanisms of HER on HCC were evaluated in HepG2 and Hep3B cells. The in vitro experiments demonstrated that HER significantly induced G0/G1 phase arrest, inhibited the proliferation and promoted cell apoptosis in liver cancer cell lines. In the mechanisms, the antitumor effects of HER on liver cancer cells were mediated by phosphatidylinositol 3-kinase (PI3K)-protein kinase B (AKT) pathway and reactive oxygen species (ROS), simultaneously. In one way, HER inhibited the activities of PI3K-AKT pathway, which interrupt the dimer formation of cyclin-dependent kinase 4 (CDK4) and cyclin D1 (CCND1) and result to G0/G1 phase arrest. In another way, after HER treatment, ROS accumulated in liver cancer cells and caused mitochondria injury which further influenced the expression of apoptosis-related proteins and eventually resulted to HepG2 and Hep3B cell apoptosis. In addition, HER showed a tumor restrain function in HepG2 and Hep3B bearing nude mice. Overall, these findings indicated that HER is a promising antitumor drug, which may provide a new direction for clinical HCC treatment.
