Induction and Evaluation of Depression in Mice Through Chronic Stress Exposure

Source: Yan, Z., et al. Evaluating the Anti-depression Effect of Xiaoyaosan on Chronically-stressed Mice. J. Vis. Exp. (2019).The video demonstrates the process of establishing a mouse model of chronic stress-induced depression and assessing depressive behaviors. The chronic application of various stressors triggers the release of corticosterone, leading to neuronal over-excitation and eventual neuronal death, which results in depression-like symptoms in the...

Chronic Stress Shifts Effort-Related Choice Behavior in a Y-Maze Barrier Task in Mice09:37

Chronic Stress Shifts Effort-Related Choice Behavior in a Y-Maze Barrier Task in Mice

The Y-maze barrier task is a behavior test that examines motivation to expend effort for reward. Here, we discuss testing multiple well-validated chronic stressors including chronic corticosterone and social defeat stress with this behavior, as well as the novel chronic non-discriminatory social defeat stress (CNSDS), which is effective in...

Cell Cycle-specific Measurement of γH2AX and Apoptosis After Genotoxic Stress by Flow Cytometry08:21

Cell Cycle-specific Measurement of γH2AX and Apoptosis After Genotoxic Stress by Flow Cytometry

The presented method combines the quantitative analysis of DNA double-strand breaks (DSBs), cell cycle distribution and apoptosis to enable cell cycle-specific evaluation of DSB induction and repair as well as the consequences of repair...

Implantation of a Carotid Cuff for Triggering Shear-stress Induced Atherosclerosis in Mice07:51

Implantation of a Carotid Cuff for Triggering Shear-stress Induced Atherosclerosis in Mice

The constricting cuff presented in this article is designed to induce atherosclerosis in the murine common carotid artery. Due to the conical shape of its inner lumen the implanted cuff generates well-defined regions of low, high and oscillatory shear stress triggering the development of atherosclerotic lesions of different inflammatory...

Activation of Apoptosis by Cytoplasmic Microinjection of Cytochrome c07:42

Activation of Apoptosis by Cytoplasmic Microinjection of Cytochrome c

In this protocol, we describe the direct cytoplasmic microinjection of cytochrome c protein into fibroblasts and primary sympathetic neurons. This technique allows for the introduction of cytochrome c protein into the cytoplasm of cells and mimics the release of cytochrome c from mitochondria, which occurs during...
