Possible Interaction: Quercetin and Tyrosine

“Ang II caused a rapid tyrosine phosphorylation of Src homology and collagen (Shc), which was inhibited by quercetin.”

“Finally, quercetin increased the interaction between EGFR and Cbl, and also induced the tyrosine phosphorylation of Cbl.”

“ Quercetin and its structurally analogous (+)-catechin inhibited the peroxynitrite-dependent upregulation of Band 3 tyrosine phosphorylation.”

“ Quercetin was found to downregulate the activity of syk, which is upstream in the Band 3 tyrosine phosphorylation cascade, and partially prevented peroxynitrite-mediated phosphotyrosine phosphatase inhibition.”

“ Quercetin enhanced heat‐induced tyrosine phosphorylation of MAP kinase.”

“However, quercetin , kaempferol, and galangin each affect the oxidation of L-tyrosine in somewhat different ways.”

“Furthermore, DMSO and quercetin enhanced the level of tyrosine phosphorylation of cold-stored sperm.”

“The synchronous fluorescence spectra demonstrated that QUE interacted with both tyrosine and tryptophan residues of BSA in three solvent systems.”

“A strong inhibitory effect of quercetin on the tyrosine phosphorylation of several proteins (40, 42, 43, 45, 46 and 75 kDa) was observed when the neutrophils were pretreated with different concentrations of quercetin.”

“ Quercetin was found to enhance tyrosine phosphorylation in the insulin-signaling pathway and to downregulate the expression levels of the sterol regulatory element-binding protein-1c (SREBP-1c) and fatty acid synthase (FAS) in quercetin-treated groups, compared to the control group.”
