    Isoquercitrin and polyphosphate co-enhance mineralization of human osteoblast-like SaOS-2 cells via separate activation of two RUNX2 cofactors AFT6 and Ets1.[Pubmed: 24726443]
    Isoquercitrin, a dietary phytoestrogen, is a potential stimulator of bone mineralization used for prophylaxis of osteoporotic disorders. Here we studied the combined effects of Isoquercitrin, a cell membrane permeable 3-O-glucoside of quercetin, and polyphosphate [polyP], a naturally occurring inorganic polymer inducing bone formation, on mineralization of human osteoblast-like SaOS-2 cells. Both compounds Isoquercitrin and polyP induce at non-toxic concentrations the mineralization process of SaOS-2 cells. Co-incubation experiments revealed that Isoquercitrin (at 0.1 and 0.3μM), if given simultaneously with polyP (as Ca(2+) salt; at 3, 10, 30 and 100μM) amplifies the mineralization-enhancing effect of the inorganic polymer. The biomineralization process induced by Isoquercitrin and polyP is based on two different modes of action. After incubation of the cells with Isoquercitrin or polyP the expression of the Runt-related transcription factor 2 [RUNX2] is significantly upregulated. In addition, Isoquercitrin causes a strong increase of the steady-state-levels of the two co-activators of RUNX2, the activating transcription factor 6 [ATF6] and the Ets oncogene homolog 1 [Ets1]. The activating effect of Isoquercitrin occurs via a signal transduction pathway involving ATF6, and by that, is independent from the induction cascade initiated by polyP. This conclusion is supported by the finding that Isoquercitrin upregulates the expression of the gene encoding for osteocalcin, while polyP strongly increases the expression of the Ets1 gene and of the alkaline phosphatase. We show that the two compounds, polyP and Isoquercitrin, have a co-enhancing effect on bone mineral formation and in turn might be of potential therapeutic value for prevention/treatment of osteoporosis.

    Isoquercitrin inhibits the progression of pancreatic cancer in vivo and in vitro by regulating opioid receptors and the mitogen-activated protein kinase signalling pathway.[Pubmed: 25434366]
    Isoquercitrin, which is one of the flavonoids found in Bidens pilosa extracts, has a significant antitumour effect. However, the antitumour effect of Isoquercitrin and its mechanism of action remain unclear. The objective of the present study was to investigate the effect of Isoquercitrin on the progression of pancreatic cancer and to further understand the biological characteristics of the participation of Isoquercitrin in the progression of pancreatic cancer. In vitro, we found that a therapeutic dose of Isoquercitrin significantly inhibited proliferation, promoted apoptosis and induced cell cycle arrest within the G1 phase in pancreatic cancer cells. Isoquercitrin activated caspase-3, -8 and -9 and reduced the mitochondrial membrane potential. In addition, Isoquercitrin inhibited the expression level of the δ opioid receptor; however, Isoquercitrin had no effect on the κ and µ opioid receptors. Furthermore, Isoquercitrin inhibited extracellular signal-regulated kinase (ERK) phosphorylation and promoted c-Jun N-terminal kinase (JNK) phosphorylation. In vivo, we found that a therapeutic dose of Isoquercitrin significantly inhibited xenograft growth in nude mice. In summary, the present study demonstrated that Isoquercitrin inhibits human pancreatic cancer progression in vivo and in vitro and that its molecular mechanism may be closely related to opioid receptors and to the activation of the mitogen-activated protein kinase (MAPK) signalling pathway.

    Isoquercitrin inhibits the progression of liver cancer in vivo and in vitro via the MAPK signalling pathway.[Pubmed: 24676882]
    The purpose of the present study was to investigate the impact of Isoquercitrin, the flavonoid from Bidens bipinnata L. extract, on the progression of liver cancer and to achieve a deeper understanding of the biological characteristics of Isoquercitrin's involvement in the progression of liver cancer. In the in vitro experiments, Isoquercitrin was found to strongly inhibit the proliferation of human liver cancer cells, promote the apoptosis of human liver cancer cells, and block the cell cycle in the G1 phase. Isoquercitrin activated caspase-3, -8 and -9, inhibited the expression level of ERK and p38MAPK protein phosphorylation, and promoted the phosphorylation of JNK. Additionally, Isoquercitrin reduced the expression level of PKC in human liver cancer cells. In the in vivo experiments, Isoquercitrin was also found to significantly inhibit the growth of transplanted tumours in nude mice. The present study confirmed that Isoquercitrin could inhibit the progression of human liver cancer in vivo and in vitro, and the molecular mechanism of Isoquercitrin may be closely associated with the MAPK and PKC signalling pathways.

    Protective effects of flavonol isoquercitrin, against 6-hydroxy dopamine (6-OHDA)-induced toxicity in PC12 cells.[Pubmed: 24443837 ]
    This study investigated the neuroprotective effects of flavonol Isoquercitrin against toxicity induced by 6-hydroxy-dopamine (6-OHDA) in rat pheochromocytoma (PC12) cells. METHODS: PC12 cells were pretreated with different concentrations of Isoquercitrin for 4, 8 and 12 hours and incubated with 6-OHDA for 24 hours to induce oxidative cell damage. RESULTS: A significant cytoprotective activity was observed in Isoquercitrin pre-treated cells in a dose-dependent manner. There was a significant increase (P < 0.01) in the antioxidant enzymes namely superoxide dismutase, catalase, glutathione peroxidase, and glutathione in Isoquercitrin pretreated cells compared to cells incubated with 6-OHDA alone. Isoquercitrin significantly reduced (P < 0.01) lipid peroxidation in 6-OHDA treated cells. These results suggested that Isoquercitrin protects PC 12 cells against 6-OHDA-induced oxidative stress. CONCLUSIONS: The present study suggests the protective role of Isoquercitrin on 6-hydroxydopamine-induced toxicity by virtue of its antioxidant potential. Isoquercitrin could be a potential therapeutic agent against neurodegeneration in Parkinson's disease.

    Isoquercitrin suppresses colon cancer cell growth in vitro by targeting the Wnt/β-catenin signaling pathway.[Pubmed: 25359775]
    To investigate whether Isoquercitrin affects Wnt/β-catenin signaling. Our data provide strong support for an inhibitory effect of Isoquercitrin on Wnt/β-catenin, where the flavonoid acts downstream of β-catenin translocation to the nuclei. Isoquercitrin affects Xenopus axis establishment, reverses double axes and the LiCl hyperdorsalization phenotype, and reduces Xnr3 expression. In addition, this flavonoid shows anti-tumoral effects on colon cancer cells (SW480, DLD-1, and HCT116), whereas exerting no significant effect on non-tumor colon cell (IEC-18), suggesting a specific effect in tumor cells in vitro. Taken together, our data indicate that Isoquercitrin is an inhibitor of Wnt/β-catenin and should be further investigated as a potential novel anti-tumoral agent.
