Unmasking Root Causes of Stress/Anxiety

i-Fect Knocks Down Suspected Stress/Anxiety Receptor
The molecular pathogenesis underlying anxiety disorders is still unclear. Here, the authors demonstrate that myristoylated alanine-rich C-kinase substrate like 1 (MARCKSL1) overexpression in mice increases spine formation in the amygdala and induces stress hormone upregulation and anxiety-like behaviors. Suppression of MARCKSL1 in the amygdala ameliorates both the increase in stress hormones and the elevated anxiety-like behaviors. Our results indicate that MARCKSL1 expression in the amygdala plays an important role in anxiety-like behaviors.

This was proved, in part, by the knockdown of MARCKSL1 in vivo in mice using our i-Fect^TM. Tanaka, Takashi; Shimizu, Shoko; Ueno, Masaki; Fujihara, Yoshitaka; Ikawa, Masahito; Miyata, Shingo.

(A and B) For the in vivo experiment, siRNA (blue) was injected into the CeA (total 4 sites) with i-Fect siRNA transfection reagents 5 days prior to behavioral tests. (C) In situ hybridization for Marcksl1 mRNA (blue) in the amygdala after injection of Marcksl1 siRNA into the CeA of Tg/Tg mice. Scale bar, 200 μm.

MARCKSL1 knockdown mice (WT + control siRNA, n = 7; Tg/Tg + control siRNA, n = 7; Tg/Tg + Marcksl1 siRNA, n = 8).

HUVECS in 3-D Action

Form Vascular Networks in Microfluidics Model
In this study, the authors developed a 3D functional human microvascular network in a microfluidic device. The established model enables Neuromics GFP-labeled human umbilical vein endothelial cells to form vessel-like microtissues and have physiological functions which are closer to cells in human blood vessels. The perfusable microvasculature allows the delivery of nutrients, and oxygen, as well as flow-induced mechanical stimuli into the luminal space of the endothelium. The microflow effectively mimic the blood flow in human vessels.

This in-vivo like model is then used for toxicity assays-Yan Li, Qing-Meng Pi, Peng-Cheng Wang, Lie-Ju Liu, Zheng-Gang Han,Yang Shao, Ying Zhai, Zheng-Yu Zuo, Zhi-Yong Gong, Xu Yang and Yang Wu.
