The present investigation has been undertaken to reveal the protective mechanism of polyphenolics extract of whole wheat grains (WWGPE), ferulic acid and apigenin against doxorubicin (Dox)-induced cardio-toxicity. WWGPE, apigenin, and ferulic acid exhibited concentration dependent cyto-protective effect against Dox (1 μM) in rat cardiomyocytes. Dox treatment significantly (p < 0.01) induced oxidative stress in the myocardial cells via excessive ROS production, increase in iNOS expression, NADPH oxidase activation, Nrf-2/HO-1 impairment, and inactivation of cellular redox defense system. In addition, Dox significantly (p < 0.01) activated MAP kinases, NF-κB, and apoptosis in cardiac cells; while, significant (p < 0.01) impairment in PI3K/Akt/mTOR signaling was observed in Dox-treated myocardial cells. On the other hand, WWGPE, apigenin, and ferulic acid significantly (p < 0.05-0.01) attenuated Dox-induced redox stress and oxidative stress-mediated signal transduction in myocardial cells. WWGPE, apigenin, and ferulic acid treatment also could significantly (p < 0.05-0.01) reinstate Dox-mediated changes in blood parameters in rats. Histological assessments were in agreement with the biochemical findings. Results showed that, WWGPE exhibited better cardio-protective effect over ferulic acid and apigenin, which may be due to the synergy between the comprising compounds and better oral bioavailability of dietary antioxidant molecules from whole phenolic extract.

Allergic reaction to wheat that is triggered by the immune system.
A plant genus of the family POACEAE that is the source of wheat grain. A hybrid with rye (SECALE CEREALE) is called TRITICALE. The seed is ground into FLOUR and used to make BREAD, and is the source of WHEAT GERM AGGLUTININS.
Lectins purified from the germinating seeds of common wheat (Triticum vulgare); these bind to certain carbohydrate moieties on cell surface glycoproteins and are used to identify certain cell populations and inhibit or promote some immunological or physiological activities. There are at least two isoforms of this lectin.
A diet which is devoid of GLUTENS from WHEAT; BARLEY; RYE; and other wheat-related varieties. The diet is designed to reduce exposure to those proteins in gluten that trigger INFLAMMATION of the small intestinal mucosa in patients with CELIAC DISEASE.
A disturbance in the prooxidant-antioxidant balance in favor of the former, leading to potential damage. Indicators of oxidative stress include damaged DNA bases, protein oxidation products, and lipid peroxidation products (Sies, Oxidative Stress, 1991, pxv-xvi).
