Project description:To further analyze the effect of aging and caloric restriction in the microRNA expression, we have employed microarray expression profiling as a discovery platform to identify differentially expressed microRNAs in middle-aged animals and the impact of caloric restriction in the microRNA expression profile. Subcutaneous and visceral adipose tissue were extracted from 3 groups of mice: 3 month-old, 12 month-old fed ad libitum and 12 month-old fed with a caloric restricted diet. Comparisons between young and middle-aged animals in subcutaneous and visceral adipose tissue, and between the 12 month old ad libitum and 12 month old caloric restricted diet in both adipose depots were made.
Project description:To describe the protein profile in hippocampus, colon and ileum tissue’ changing after the old faeces transplants, we adopted a quantitative label free proteomics approach.
