Researchers at the Obesity Research Unit of the University of Helsinki have found that obesity clearly reduces mitochondrial gene expression in fat tissue, or adipose tissue. Mitochondria are important cellular powerplants which process all of our energy intake. If the pathways associated with breaking down nutrients are lazy, the changes can often have health-related consequences.
A total of 49 pairs of identical twins discordant for body weight participated in the study conducted at the University of Helsinki: their body composition and metabolism were studied in detail, and biopsies from adipose and muscle tissue were collected. Multiple techniques for analysing the genome-wide gene expression, the proteome and the metabolome were used in the study.
The study was recently published in the journal Cell Reports Medicine.
According to the findings, the pathways responsible for…
