Information om forskning och undervisning

Mitochondria control ATP production and energy expenditure. Therefore it is of great interest that defects of mitochondrial dysfunction can lead either to thinness or overweight. Adipose tissue is a key player in obesity-related metabolic dysfunction. These obesity-related changes increase person´s risk of diabetes, insulin resistance and cardiovascular disease. We have collected fat, muscle and serum samples from 22 mitochondrial disease patients, 24 relatives and 30 healthy controls. Both DNA and RNA were isolated from fat and muscle samples. Total cellular RNA from adipose tissue of selected patients and controls was used for microarray experiment. The data has been normalized and confirmed by q-PCR on selected changed transcripts. Differentially expressed genes with significant change (p value < 0.05) were then used for a pathway analysis. MtDNA copy number in fat and muscle was established by two quantitative PCR methods (using Taqman and SyberGreen probes). Interestingly, in adipose tissue of healthy individuals mtDNA content tends to increase with age. All our mitochondrial disease patients showed mild or extensive decline of mtDNA copy number in the adipose tissue regardless their BMI. This result might suggest that the mtDNA depletion in our mitochondrial disease patient is caused by genetic defects in mitochondrial replication and maintenance.
