Abstract

Objective: To study the role of microbial-derived antioxidants (MA) based on the model of diquat-induced oxidative stress, endoplasmic reticulum stress, apoptosis and function in mice. Methods: 18 female C57BL/6 mice with body mass of 16~18 g were selected and randomly divided into 3 groups with 6 mice in each group. After 22 days of feeding, model and antioxidant group mice were intraperitoneally injected with diquat solution and control group were injected with same amount of isotonic saline. The content of free radical, MDA, antioxidant enzyme activity, aspartate aminotransferase (AST) and alanine aminotransferase (ALT) activity were detected according to the instructions of the kit. QRT-PCR was used to detect the expression of endoplasmic reticulum stress and apoptosis-related genes. One-way analysis of variance was used for data comparison between groups. Results: Hydrogen peroxide (H(2)O(2)) in the control group, model group and antioxidant group was (8.74 ± 1.38), (11.44 ± 1.01), (9.81 ± 0.98) mmol/g prot, respectively, and the difference between the groups was statistically significant (F = 7.640, P < 0.05). MDA content in the control, model and antioxidant group were (0.65 ± 0.07), (0.86 ± 0.18), (0.70 ± 0.05) nmol/mg ...Continue Reading

Apoptosis

Apoptosis is a specific process that leads to programmed cell death through the activation of an evolutionary conserved intracellular pathway leading to pathognomic cellular changes distinct from cellular necrosis
