[αCGRP Transgenic Mice Display Typical Physiologic Features].

 Calcitonin gene-related peptide (CGRP) plays an important role in several physiological processes such as vasodilation, cardiovascular homeostasis and transmission of pain. Here we report the generation of a transgenic mouse overexpressing αCGRP and the impact of this on baseline physiological responses. αCGRP transgenic mice displayed significantly increased αCGRP mRNA levels in the kidney, heart and hippocampus.

[Effects of 15-day chronic stress on behavior and neurological changes in the hippocampus of ICR mice].

  Numerous rodent models of depression have been reported, most requiring a long experimental period and significant effort. We explored a new potential mouse model for depression by investigating whether exposure to a 15-day chronic stress paradigm could induce depression-like behavior in ICR mice. Animals in the stress-exposed groups were subjected to 3 h of restraint while immersed in a 28°C water bath daily for 15 consecutive days.
