Panaxydol attenuates ferroptosis against LPS-induced acute lung injury in mice by Keap1-Nrf2/HO-1 pathway
J Transl Med 2021 Mar 2;19(1):96.PMID:33653364DOI:10.1186/s12967-021-02745-1.
Background: Acute lung injury (ALI)/acute respiratory distress syndrome (ARDS) induces uncontrolled and self-amplified pulmonary inflammation, and has high morbidity and mortality rates in critically ill patients. In recent years, many bioactive ingredients extracted from herbs have been reported to effectively ameliorate ALI/ARDS via different mechanisms. Ferroptosis, categorized as regulated necrosis, is more immunogenic than apoptosis and contributes to the progression of ALI. In this study, we examined the impact of Panaxydol (PX), isolated from the roots of Panax ginseng, on lipopolysaccharide (LPS)-induced ALI in mice. Methods: In vivo, the role of PX on LPS-induced ALI in mice was tested by determination of LPS-induced pulmonary inflammation, pulmonary edema and ferroptosis. In vitro, BEAS-2B cells were used to investigate the molecular mechanisms by which PX functions via determination of inflammation, ferroptosis and their relationship. Results: Administration of PX protected mice against LPS-induced ALI, including significantly ameliorated lung pathological changes, and decreased the extent of lung edema, inflammation, and ferroptosis. In vitro, PX inhibited LPS-induced ferroptosis and inflammation in bronchial epithelial cell line BEAS-2B cells. The relationship between ferroptosis and inflammation was investigated. The results showed that ferroptosis mediated inflammation in LPS-treated BEAS-2B cells, and PX might ameliorate LPS-induced inflammation via inhibiting ferroptosis. Meanwhile, PX could upregulate Keap1-Nrf2/HO-1 pathway, and selective inhibition of Keap1-Nrf2/HO-1 pathway significantly abolished the anti-ferroptotic and anti-inflammatory functions of PX in LPS-treated cells. Conclusion: PX attenuates ferroptosis against LPS-induced ALI via Keap1-Nrf2/HO-1 pathway, and is a promising novel therapeutic candidate for ALI.
Panaxydol Derived from Panax notoginseng Promotes Nerve Regeneration after Sciatic Nerve Transection in Rats
J Integr Neurosci 2022 Jun 7;21(4):109.PMID:35864761DOI:10.31083/j.jin2104109.
Background: Peripheral nerve regeneration is a coordinated process of Schwann cell (SC) reprogramming and intrinsic neuronal growth program activation. Panaxydol (PND) is a strong biologically active traditional Chinese medicine monomer extracted from Panax notoginseng rhizomes. In vitro, PND protects neurons and SCs from injury and stimulates the expression and secretion of neurotrophic factors (NTFs) by SCs. We hypothesized that PND may also promote peripheral nerve regeneration in adult animals. Methods: PND (10 mg/kg body weight) was injected intraperitoneally into the Sprague-Dawley (SD) rats for two consecutive weeks after sciatic nerve transection. The morphology of the repaired sciatic nerve was evaluated after 16 weeks, and sensory and motor function recovery was evaluated using functional and behavioral techniques. Results: PND was biologically safe at an injection dose of 10 mg/kg/day. After 14 days, it significantly increased the myelination of regenerated nerve fibers, and promoted sensory and motor function recovery. In the early stage of injury, PND significantly upregulated the mRNA expression of brain-derived neurotrophic factor (BDNF) and its receptors in distal injured nerves, which may represent a possible mechanism by which PND promotes nerve regeneration in vivo. Conclusions: Our study demonstrated that PND leads to sensory and motor recovery in a sciatic nerve transection model rat. Furthermore, we showed that BDNF mRNA level was significantly increased in the injured distal nerve, potentially contributing to the functional recovery. Further research is warrantied to examine whether direct injection is a more efficient method to increase BDNF expression compared to an exogenous BDNF administration.
Molecular mechanism of Panaxydol on promoting axonal growth in PC12 cells
Neural Regen Res 2018 Nov;13(11):1927-1936.PMID:30233066DOI:10.4103/1673-5374.239439.
Nerve growth factor (NGF) promotes axonal growth in PC12 cells primarily by regulating the RTK-RAS-MEK-ERK pathway. Panaxydol, a polyacetylene isolated from Panax notoginseng, can mimic the effects of NGF. Panaxydol promotes neurite outgrowth in PC12 cells, but its molecular mechanism remains unclear. Indeed, although alkynol compounds such as Panaxydol can increase intracellular cyclic adenosine 3',5'-monophosphate (cAMP) levels and the ERK inhibitor U0126 inhibits alkynol-induced axonal growth, how pathways downstream of cAMP activate ERK have not been investigated. This study observed the molecular mechanism of panaxydol-, NGF- and forskolin-induced PC12 cell axon growth using specific signaling pathway inhibitors. The results demonstrated that although the RTK inhibitor SU5416 obviously inhibited the growth-promoting effect of NGF, it could not inhibit the promoting effect of Panaxydol on axonal growth of PC12 cells. The adenylate cyclase inhibitor SQ22536 and cAMP-dependent protein kinase inhibitor RpcAMPS could suppress the promoting effect of forskolin and Panaxydol on axonal growth. The ERK inhibitor U0126 inhibited axonal growth induced by all three factors. However, the PKA inhibitor H89 inhibited the promoting effect of forskolin on axonal growth but could not suppress the promoting effect of Panaxydol. A western blot assay was used to determine the effects of stimulating factors and inhibitors on ERK phosphorylation levels. The results revealed that NGF activates the ERK pathway through tyrosine receptors to induce axonal growth of PC12 cells. In contrast, Panaxydol and forskolin increased cellular cAMP levels and were inhibited by adenylyl cyclase inhibitors. The protein kinase A inhibitor H89 completely inhibited forskolin-induced axonal outgrowth and ERK phosphorylation, but could not inhibit panaxydol-induced axonal growth and ERK phosphorylation. These results indicated that Panaxydol promoted axonal growth of PC12 cells through different pathways downstream of cAMP. Considering that exchange protein directly activated by cAMP 1 (Epac1) plays an important role in mediating cAMP signaling pathways, RNA interference experiments targeting the Epac1 gene were employed. The results verified that Epac1 could mediate the axonal growth signaling pathway induced by Panaxydol. These findings suggest that compared with NGF and forskolin, Panaxydol elicits axonal growth through the cAMP-Epac1-Rap1-MEK-ERK-CREB pathway, which is independent of PKA.
Panaxydol inhibits the proliferation and induces the differentiation of human hepatocarcinoma cell line HepG2
Chem Biol Interact 2009 Sep 14;181(1):138-43.PMID:19450571DOI:10.1016/j.cbi.2009.04.015.
Panaxydol, a polyacetylene compound isolated from Panax ginseng, exerts anti-proliferative effects against malignant cells. No previous study, however, has been reported on its effects on hepatocellular carcinoma cells. Here, we investigated the effects of Panaxydol on the proliferation and differentiation of human hepatocarcinoma cell line HepG2. We studied by electronic microscopy of morphological and ultrastructural changes induced by Panaxydol. We also examined the cytotoxicities of Panaxydol against HepG2 cells using the 3-(4,5-dimethyl-2-thiazolyl)-2,5-diphenyl tetrazolium bromide assay and the effect of Panaxydol on cell cycle distributions by flow cytometry. We investigated the production of liver proteins in panaxydol-treated cells including alpha-fetoprotein and albumin and measured the specific activity of alkaline phosphatase and gamma-glutamyl transferase. We further investigated the effects of Panaxydol on the expression of Id-1, Id-2, p21 and pRb by RT-PCR or immunoblotting analysis. We found that Panaxydol inhibited the proliferation of HepG2 cells and caused morphological and ultrastructural changes in HepG2 cells resembling more mature forms of hepatocytes. Moreover, Panaxydol induced a cell cycle arrest at the G(1) to S transition in HepG2 cells. It also significantly decreased the secretion of alpha-fetoprotein and the activity of gamma-glutamyl transferase. By contrast, Panaxydol remarkably increased the secretion of albumin and the alkaline phosphatase activity. Furthermore, Panaxydol increased the mRNA content of p21 while reducing that of Id-1 and Id-2. Panaxydol also increased the protein levels of p21, pRb and the hypophosphorylated pRb in a dose-dependent manner. These findings suggest that Panaxydol is of value for further exploration as a potential anti-cancer agent.
Panaxydol, a component of Panax ginseng, induces apoptosis in cancer cells through EGFR activation and ER stress and inhibits tumor growth in mouse models
Int J Cancer 2016 Mar 15;138(6):1432-41.PMID:26421996DOI:10.1002/ijc.29879.
We reported previously that Panaxydol, a component of Panax ginseng roots, induced mitochondria-mediated apoptosis preferentially in transformed cells. This study demonstrates that EGFR activation and the resulting ER stress mediate panaxydol-induced apoptosis, and that Panaxydol suppresses in vivo tumor growth in syngeneic and xenogeneic mouse tumor models. In addition, we elucidated that CaMKII and TGF-β-activated kinase (TAK1) participate in p38/JNK activation by elevated cytoplasmic Ca(2+) concentration ([Ca(2+)]c). In MCF-7 cells, EGFR was activated immediately after exposure to Panaxydol, and this activation was necessary for induction of apoptosis, suggesting that Panaxydol might be a promising anticancer candidate, especially for EGFR-addicted cancer. Activation of PLCγ followed EGFR activation, resulting in Ca(2+) release from the endoplasmic reticulum (ER) via inositol triphosphate and ryanodine receptors. ER Ca(2+) release triggered mitochondrial Ca(2+) uptake indirectly through oxidative stress and ensuing ER stress. Elevated [Ca(2+)]c triggered sequential activation of calmodulin/CaMKII, TAK1 and p38/JNK. As shown previously, p38 and JNK activate NADPH oxidase. Here, it was shown that the resulting oxidative stress triggered ER stress. Among the three signaling branches of the unfolded protein response, protein kinase R-like ER kinase (PERK), but not inositol-requiring enzyme 1 or activating transcription factor 6, played a role in transmitting the apoptosis signal. PERK induced C/EBP homologous protein (CHOP), and CHOP elevated Bim expression, initiating mitochondrial Ca(2+) uptake and apoptosis. In summary, we identified roles of EGFR, the CAMKII-TAK1-p38/JNK pathway, and ER stress in panaxydol-induced apoptosis and demonstrated the in vivo anticancer effect of Panaxydol.
