Possible Interaction: Antioxidants and Proline

“It has been defined as an imbalance in the activity of pro and antioxidants.”

“To maintain health a balance between pro and anti oxidants is very necessary.”

“H2O2 and TAS modulation by Pro may contribute to the reduced P-ADMA concentration.”

“Herein, we demonstrated that proline alters antioxidant defenses and induces lipid peroxidation in the kidney of rats and the green tea extract was capable to counteract the proline-induced alterations.”

“These data suggest that antioxidants may be an effective adjuvant therapeutic to limit oxidative damage caused by proline.”

“Exogenous proline increased antioxidant enzyme activities and improved photosynthetic attributes, nutrient uptake (Mg2+, Ca2+, K+), and growth parameters in cadmium-stressed pigeon pea plants.”

“Moreover, Mo supply enhanced photosynthesis, proline , and soluble protein content, and also strengthened plant metabolism and antioxidant defense through maintaining higher activities and transcript abundance of ROS-detoxifying enzymes at the vegetative, reproductive, and maturity stages of aromatic rice plants under Cd toxicity.”

“ Proline increased Se accumulation and antioxidant enzyme activities but not either ROS accumulation or lipid peroxidation in the selenate-stressed cells.”

“These results indicate that proline increases both antioxidant enzyme activities and Se accumulation, which overall fails to ameliorate the growth inhibition by selenate and that the growth inhibition is not accounted for only by ROS accumulation.”

“Plant growth, concentration of photosynthetic pigments, total nitrogen, and carbohydrates reduced, whereas enzymatic [catalase (CAT), superoxide dismutase (SOD), and ascorbate peroxidase (APX)] and non-enzymatic proline and total phenolics) antioxidants increased upon HM stress.”

“In conclusion, The sequence combination of antioxidants and proline caused improvement in plant growth under drought stress by up-regulating the antioxidant defense system and osmolyte synthesis.”
