A Novel Marker for Brown Fat Activity

The present invention is a technology that significantly simplifies the measurement of BAT by PCR-based quantification of exosomal microRNA-92a in serum. Exosomal miR-92a levels inversely correlate with BAT activity. This novel method is as the first of its kind qualified to routinely measure the BAT activity in large cohorts of patients.
The measurement of BAT activity is not only important in the diagnosis and treatment of weight-related diseases, but is also a screening tool for the development of drugs that regulate the BAT activity. Such drugs are of use in pathological leanness (e.g. cachexia), obesity and other metabolic diseases.
The invention has been validated by studies in mice and man. On behalf of the University of Bonn, PROvendis offers access to rights for commercial use as well as the opportunity for further co-development. In case of interest we will be pleased to inform you about the patent status.
