Literature evidence |
Flavonoids inhibit cell proliferation and induce apoptosis and autophagy through downregulation of PI3Kγ mediated PI3K/AKT/mTOR/p70S6K/ULK signaling pathway in human breast cancer cells. |

Gene or Protein evidence |
Taken together, these data demonstrated that isorhamnetin could significantly inhibit the invasion of MDA-MB-231 cells by downregulating the expression and activity of MMP-2 and MMP-9, which was potentially associated with the suppression of p38 MAPK and STAT3. |
Target pathways |
PI3K/AKT/mTOR/p70S6K/ULK signaling pathway
PI3K/Akt and NF- κ B Pathways |
IC50 |
NA |
Potency |
Importantly, treatment with these flavonoids decreased the levels of PI3Kγ-p110, phospho-PI3K, phospho-AKT, phospho-mTOR, phospho-p70S6K, and phospho-ULK. Pretreatment with PI3Kγ specific inhibitor AS605240 potentiated flavonoids-mediated inactivation of AKT, mTOR, p70S6K, ULK, and apoptosis. |
Cell line/ mice model |
B16F10, MCF-7, MDA-MB-231 |
Additional information |
The examination on molecular mechanism revealed that IH could suppress the phosphorylation of Akt and the translocation of NF-κB, which are key factors in apoptosis-related pathways.
We also detected that this process was related to the bifunctional 6-phosphofructo-2-kinase/fructose-2,6-bisphosphatases 4 (PFKFB4) by PFKFB4 knockdown experiment. |
