Biography

Professor Justin Rochford leads a research team at the Rowett Institute examining the effects of fat tissue on health. This includes multiple local, national and international collaborations that investigate how poor function of fat tissue can lead to diseases such as type 2 diabetes, liver disease, vascular disease and cancers. Poorly functioning fat tissue often occurs in overweight and obesity, which is associated with these diseases. The Rochford lab is part of the Aberdeen Cardiovascular and Diabetes Centre:

Professor Rochford's laboratory is particularly known for contributions to understanding a rare but very serious condition called lipodystrophy. Affected individuals have fat tissue that doesn't function properly. Normally, excess calories from food should be stored safely in fat tissue, keeping them away from other organs where they would do harm. In people with lipodystrophy, because their fat tissue doesn't work properly, fat can start to appear in organs like the liver, the pancreas and the muscle making them very unwell.

We undertake research that aims to understand what goes wrong in the fat cells to cause lipodystrophy so we can understand the disease better. We also study how poorly-functioning fat tissue affects the body. This can lead us to new treatments for common disease associated with overweight and obesity as well as for lipodystrophy. In addition, we develop and test treatments for lipodystrophy in order to identify desperately needed new ways to treat this condition.

Research Overview

Background:

My group focuses on the molecular mechanisms controlling adipocyte differentiation and the functions of mature fat cells generated by this process. Humans turn over adipocytes at a rate of approximately 10% each year so adipocyte development is a process relevant throughout life. Having appropriately functioning fat cells is critical for human health as these cells provide an essential safe store for dietary nutrients, particularly lipids, and protect other tissues in the body from their harmful effects. This is perhaps most clearly demonstrated by individuals with severe forms of lipodystrophy who fail to appropriately develop or maintain adipose tissue and suffer severe insulin resistance and metabolic disease as a consequence. Lipid is stored in adipocytes in a large fat droplet mainly comprised of triglyceride. The storage and release of this lipid is highly regulated and is a defining function of mature adipocytes. In addition adipocytes secrete many factors that affect appetite, insulin sensitivity and metabolic health.  In obesity, despite abundant adipose tissue, the adipocytes appear to be dysfunctional and their lipid storage capacity may be exceeded, leading to overflow of lipids to other tissues. For this reason obese individuals may suffer similar metabolic problems to patients with lipodystrophy. Overall, this means that understanding the development and function of adipocytes may lead us to new therapies by which these can be modified to treat both rare lipodystrophies and common obesity.

Lipodystrophy genes as critical regulators of human fat development:

A key approach we are taking is to investigate the functional roles of genes known to cause lipodystrophy in humans, particularly those whose disruption causes severe loss of adipose tissue. Evidently the products of these genes are critical for the development of adipose tissue in humans, however, relatively little is known about their molecular role in developing adipocytes. We use a range of techniques to understand the function of these proteins including immunofluorescence/confocal microscopy to examine subcellular localisation and trafficking, transcriptional and protein analyses to determine their importance in adipogenesis, binding studies and proteomics to identify and characterise novel binding partners and lipidomics to investigate their involvement in lipid biosynthesis, a key component of adipocyte differentiation.

This work is exemplified by our studies of the protein seipin, encoded by the gene BSCL2. Patients with disruption of seipin have almost no detectable adipose tissue and we were the first to show that this may result from an inability to make new fat cells from stem cells lacking seipin. However, the precise function of seipin has remained unknown until very recently. We have previously shown that seipin acts as a binding protein for known regulators of adipogenesis which may at least partly explain why it is needed for adipocyte development. However, we have also identified multiple other binding proteins, both in developing and in mature adipocytes. A major component of our research is to investigate these further both in vitro and in vivo.

Understanding what the products of lipodystrophy genes do, the pathways they influence and the proteins they regulate will give key insights into human adipose tissue development and function. By identifying novel pathways and proteins that can influence adipocyte function, this work may also reveal new therapeutic targets for the treatment of common obesity and metabolic disease. This work is funded by the BBSRC, Diabetes UK, the EFSD, The Wellcome Trust and the MRC.
