Fecha de publicación: | 27-ene-2021 | Editor: | American Chemical Society | Citación: | Journal of Agricultural and Food Chemistry 69(5): 1536-1554 (2021) | Resumen: | Protein functional interactions could explain the biological response of secoiridoids (SECs), main phenolic compounds in virgin olive oil (VOO). The aim was to assess protein¿protein interactions (PPIs) of the aorta gap junction alpha-1 (GJA1) and the heart peptidyl-prolyl cis-trans isomerase (FKBP1A), plus the phosphorylated heart proteome, to describe new molecular pathways in the cardiovascular system in rats using nanoliquid chromatography coupled with mass spectrometry. PPIs modified by SECs and associated with GJA1 in aorta rat tissue were calpain, TUBA1A, and HSPB1. Those associated with FKBP1A in rat heart tissue included SUCLG1, HSPE1, and TNNI3. In the heart, SECs modulated the phosphoproteome through the main canonical pathways PI3K/mTOR signaling (AKT1S1 and GAB2) and gap junction signaling (GAB2 and GJA1). PPIs associated with GJA1 and with FKBP1A, the phosphorylation of GAB2, and the dephosphorylation of GJA1 and AKT1S1 in rat tissues are promising protein targets promoting cardiovascular protection to explain the health benefits of VOO. | Versión del editor: | http://dx.doi.org/10.1021/acs.jafc.0c07164 | URI: | http://hdl.handle.net/10261/262119 | DOI: | 10.1021/acs.jafc.0c07164 | Identificadores: | doi: 10.1021/acs.jafc.0c07164 e-issn: 1520-5118 issn: 0021-8561 |
