Description:

Notoginsenoside Ft1 is a novel stimulator of angiogenesis, it stimulates angiogenesis via HIF-1α-mediated VEGF expression, with PI3K/AKT and Raf/MEK/ERK signaling cascades concurrently participating in the process; it has the potential therapeutic effect on human neuroblastoma, it can arrest the proliferation and elicited the apoptosis of SH-SY5Y cells possibly via p38 MAPK and ERK1/2 pathways.Notoginsenoside Ft1 activates both glucocorticoid and estrogen receptors to induce endothelium-dependent, nitric oxide-mediated relaxations in rat mesenteric arteries. Notoginsenoside Ft1 also provides a great potential application of it in clinics for patients with diabetic foot ulcers, it may accelerate diabetic wound healing by orchestrating multiple processes, including promoting fibroblast proliferation, enhancing angiogenesis, and attenuating inflammatory response.

p38 MAPK and ERK1/2 pathways are involved in the pro-apoptotic effect of notoginsenoside Ft1 on human neuroblastoma SH-SY5Y cells.    

This study aims to investigate the effect and the mechanisms of Notoginsenoside Ft1, a natural compound exclusively found in P. notoginseng, on the proliferation and apoptosis of human neuroblastoma SH-SY5Y cells. 

METHODS AND RESULTS:

CCK-8 assay was used to assess the cell proliferation. Flow cytometry was performed to measure the cell cycle distribution and cell apoptosis. Hoechst 33258 staining was conducted to confirm the morphological changes of apoptotic cells. Protein expression was detected by western blot analysis and caspase 3 activity was measured by colorimetric assay kit. Among the saponins examined, Ft1 showed the best inhibitory effect on cell proliferation of SH-SY5Y cells with IC50 of 45μM. Ft1 not only arrested the cell cycle at S, G2/M stages, but also promoted cell apoptosis, which was confirmed by Hoechst 33258 staining. Further studies demonstrated that Ft1 up-regulated the protein expressions of cleaved caspase 3, phospho-p53, p21, and cyclin B1, but down-regulated that of Bcl-2. Moreover, Ft1 enhanced the phosphorylation of ERK1/2, JNK and p38 MAPK. However, the phosphorylation of Jak2 and p85 PI3K was reduced by Ft1. Inhibitors of p38 MAPK and ERK1/2 but not JNK abrogated the up-regulated protein expressions of cleaved caspase 3, p21 and down-regulated protein expression of Bcl-2 as well as elevated caspase 3 activity induced by Ft1. 

CONCLUSIONS:

Ft1 arrested the proliferation and elicited the apoptosis of SH-SY5Y cells possibly via p38 MAPK and ERK1/2 pathways, which indicates the potential therapeutic effect of it on human neuroblastoma.

Notoginsenoside Ft1 activates both glucocorticoid and estrogen receptors to induce endothelium-dependent, nitric oxide-mediated relaxations in rat mesenteric arteries.   

Panax notoginseng (Burk.) F.H. Chen has been used traditionally for the treatment of cardiovascular diseases. Notoginsenoside Ft1 (Ft1) is a bioactive saponin from the leaves of P. notoginseng. Experiments were designed to determine whether or not Ft1 is an endothelium-dependent vasodilator. 

METHODS AND RESULTS:

Rat mesenteric arteries were suspended in organ chambers for the measurement of isometric tension during phenylephrine-induced contractions. The cyclic guanosine monophosphate (cGMP) level was assessed using enzyme immunoassay. The phosphorylation and protein expressions of endothelial nitric oxide synthase (eNOS), glucocorticoid receptors (GR), estrogen receptors beta (ERß), protein kinase B (Akt) and extracellular signal-regulated kinase 1/2 (ERK1/2) were determined by Western blotting. The localization of GR and ERß were determined by immunofluorescence staining. Ft1 caused endothelium-dependent relaxations, which were abolished by l-NAME (inhibitor of nitric oxide synthases) and ODQ (inhibitor of soluble guanylyl cyclase). Ft1 increased the cGMP level in rat mesenteric arteries. GR and ERß were present in the endothelial layer and their antagonism by RU486 and PHTPP, respectively, inhibited Ft1-induced endothelium-dependent relaxations and phosphorylations of eNOS, Akt and ERK1/2. Inhibition of phosphoinositide-3-kinase (PI3K) by wortmannin and ERK1/2 by U0126 reduced Ft1-evoked relaxations and eNOS phosphorylation. 

CONCLUSIONS:

Taken in conjunction, the present findings suggest that Ft1 stimulates endothelial GRs and ERßs with subsequent activation of the PI3K/Akt and ERK1/2 pathways in rat mesenteric arteries. This results in phosphorylation of eNOS and the release of NO, which activates soluble guanylyl cyclase in the vascular smooth muscle cells leading to relaxations.

Notoginsenoside Ft1 Promotes Fibroblast Proliferation via PI3K/Akt/mTOR Signaling Pathway and Benefits Wound Healing in Genetically Diabetic Mice.    

Wound healing requires the essential participation of fibroblasts, which is impaired in diabetic foot ulcers (DFU). Notoginsenoside Ft1 (Ft1), a saponin from Panax notoginseng, can enhance platelet aggregation by activating signaling network mediated through P2Y12 and induce proliferation, migration, and tube formation in cultured human umbilical vein endothelial cells. However, whether it can accelerate fibroblast proliferation and benefit wound healing, especially DFU, has not been elucidated. 

METHODS AND RESULTS:

In the present study on human dermal fibroblast HDF-a, Ft1 increased cell proliferation and collagen production via PI3K/Akt/mTOR signaling pathway. On the excisional wound splinting model established on db/db diabetic mouse, topical application of Ft1 significantly shortened the wound closure time by 5.1 days in contrast with phosphate-buffered saline (PBS) treatment (15.8 versus 20.9 days). Meanwhile, Ft1 increased the rate of re-epithelialization and the amount of granulation tissue at day 7 and day 14. The molecule also enhanced mRNA expressions of COL1A1, COL3A1, transforming growth factor (TGF)-β1 and TGF-β3 and fibronectin, the genes that contributed to collagen expression, fibroblast proliferation, and consequent scar formation. Moreover, Ft1 facilitated the neovascularization accompanied with elevated vascular endothelial growth factor, platelet-derived growth factor, and fibroblast growth factor at either mRNA or protein levels and alleviated the inflammation of infiltrated monocytes indicated by reduced tumor necrosis factor-α and interleukin-6 mRNA expressions in the diabetic wounds. 

CONCLUSIONS:

Altogether, these results indicated that Ft1 might accelerate diabetic wound healing by orchestrating multiple processes, including promoting fibroblast proliferation, enhancing angiogenesis, and attenuating inflammatory response, which provided a great potential application of it in clinics for patients with DFU.

Platelet P2Y₁₂ receptors are involved in the haemostatic effect of notoginsenoside Ft1, a saponin isolated from Panax notoginseng.    

Among the saponins examined, Notoginsenoside Ft1 was the most potent procoagulant and induced dose-dependent platelet aggregation. 

METHODS AND RESULTS:

Notoginsenoside Ft1 reduced plasma coagulation indexes, decreased tail bleeding time and increased thrombogenesis. Moreover, it potentiated ADP-induced platelet aggregation and increased cytosolic Ca(2+) accumulation, effects that were attenuated by clopidogrel. Molecular docking analysis suggested that Notoginsenoside Ft1 binds to platelet P2Y₁₂ receptors. The increase in intracellular Ca(2+) evoked by Notoginsenoside Ft1 in HEK293 cells overexpressing P2Y₁₂ receptors could be blocked by ticagrelor. Notoginsenoside Ft1 also affected the production of cAMP and increased phosphorylation of PI3K and Akt downstream of P2Y₁₂ signalling pathways. 

CONCLUSIONS:

Notoginsenoside Ft1 enhanced platelet aggregation by activating a signalling network mediated through P2Y₁₂ receptors. These novel findings may contribute to the effective utilization of this compound in the therapy of haematological disorders.
