Our research group is working on circadian rythms and biological clock, especially on their regulations at the molecular level. In the field, Louse Uncoupling Protein 1 (UCP-1) is a mito transmembrane channel protein involved in thermogenesis and only found in brown adipose tissue. This study compares UCP-1 quantity between control mice (that at room temperature during experiment) and mice that are exposed to cold (4°C) during a couple of hours.
The lanes correspond to 8 different concentrations of total proteins in order to control the resolution by using the infrared imaging system. UCP-1 quantification studies enable us to get more information about body temperature regulation. Results between control and cold-exposed mice remain confidential.
