Fig. 2. A in The antioxidant system in Olea europaea to enhanced UV-B radiation also depends on flavonoids and secoiridoids
Fig. 2. A - Variation in reduced (AsA) and oxidized ascorbate (DHA), B - AsA redox state (AsA/DHA), C - reduced (GSH) and oxidized glutathione (GSSG), and D - and glutathione redox potential (GSH/GSSG) in leaves of O. europaea plants under control conditions and exposed to UV-B treatments (UV–B1 and UV-B2). Values are mean ± s.d. (n = 6–8). For each parameter, different letters indicate statistical differences between treatments (P <0.05) base on Holms Sidak Comparison Test.
Fig. 2 in The antioxidant system in Olea europaea to enhanced UV-B radiation also depends on flavonoids and secoiridoids
Fig. 2 presents the changes of AsA, DHA, GSH and GSSG, AsA/DHA and GSH/GSSG in O. europaea leaves after UV-B exposure. Compared with controls, plants exposed to UV-B1 had decreased levels of both AsA and DHA, which led to a maintenance of the AsA/DHA ratio (P> 0.05, Fig. 2A and B). Contrarily, GSH levels decreased while the GSSG increased significantly, decreasing the GSH/GSSG ratio (P <0.05, Fig. 2C and D). Plants exposed to UV-B2 showed an increase of DHA and, mostly, of AsA pools, which led to an increase of the AsA/DHA ratio (P <0.05, Fig. 2A and B). On other hand GSH levels also increased but GSSG was not influenced, which supported the increase of GSH/GSSG (P <0.05, Fig. 2C and D).
Fig. 3. A in The antioxidant system in Olea europaea to enhanced UV-B radiation also depends on flavonoids and secoiridoids
Fig. 3. A - secoiridoids, B - flavonoids, and C - hydroxycinnamic acid derivatives in leaves of O. europaea plants under control conditions and exposed to UV-B treatments (UV–B1 and UV-B2). Values are mean ± s.d. (n = 3). For each compound, different letters indicate statistical differences between treatments (P <0.05) base on Holms Sidak Comparison Test.
Fig. 4 in The antioxidant system in Olea europaea to enhanced UV-B radiation also depends on flavonoids and secoiridoids
Fig. 4. General overview of the metabolites and antioxidant enzymes changes in O. europaea plants under UV-B doses: moderate (UV–B1) and high (UV–B2). Relative levels [expressed as log2 (UV–B/control)] are given besides (two colored rectangles) each identified metabolite/compound or enzyme activity as a heat-map, and the upper colored rectangle refers to UV-B1 treatment while the lower one refer to the UV-B2 treatment. Protective responses in O. europaea involve the activation of both enzymatic and non-enzymatic antioxidant mechanisms to control ROS (namely H2O2) homeostasis, but the enzymatic and AsA/GSH pools are more required by higher UV doses, while polyphenols pathways are similarly solicited by both treatments. UV-B1 treatment increases SOD, CAT and GPox activities and GSSG content, reducing Gr and APX activities and the contents of AsA, DHA and GSH. UV-B2 treatment, besides SOD, CAT and GPox activation, also increases Gr activity and the contents of AsA, DHA and GSH. Flavonoids (4ʹ or 3ʹ-methoxy luteolin glucoside and 4ʹ-methoxy luteolin decrease), secoiridoids (oleuropein decrease and 2ʹʹ- methoxyoleuropein increase) and HCAds (β-hydroxyverbascoside increase) respond similarly to both UV-B doses, putatively acting as UV-B shields and/or ROS scavengers.

The transcriptomic response of murine thyroid to iodide overload and the role of the Nrf2 antioxidant system
<p>Wild-type and Nrf2(Nfe2l2) knockout male C57BL6J mice 3-4 months old were administred 0.05% NaI in their drinking water for 7 days. Control mice were administered regular drinking water. After this treatment mice were euthanized and thyroids were excised for RNA preparation and then for mRNA and miRNA RNAseq. </p> <p>The file titled "metadata RNAseq mRNA thyroid" contains the experimental information as well as the allocation of sample numbers to the relevant groups.
