Cellular metabolic deregulation is a central premise in the development of many chronic diseases including cancer. Recently, there has been renewed interest in the potential of metabolic engineering, through the use of small molecules, to achieve metabolic retransformation of abnormal cells and tissues. However, making sufficient and sustain metabolic impact though this methods can be difficult, as it requires both identification of suitable small molecule(s) and an appropriate mode of delivery. Here we present a unique approach to tackle metabolic deregulation in vivo by the use of short-chain fatty acids (SCFAs) encapsulated in a liposomal nanoparticle delivery system. We demonstrate that liposomal delivery of the SCFA acetate leads to improved metabolic fitness of several organs, including liver and adipose tissue. Furthermore, treatment of mice consuming a high fat diet resulted in a significant reduction in hepatic fat accumulation, a reduction in inflammatory markers and modulation in key genes associated with fat metabolism, including UCP2, ACOX1 and CPT1A. These phenotypic and molecular events were underpinned by modulations in the epigenetic regulation of the liver. Finally, significant antitumor effects were observed in a xenograft murine model, including significant inhibition of tumour growth, following treatment. Our results demonstrate that this delivery system, liposomal encapsulated SCFAs, can be utilised as a novel method for the treatment of malignant transformation and metabolic deregulation in vivo.

© 2013 Elsevier Ltd. All rights reserved. In the past 10 years, a number of important epidemiological and experimental studies have linked glycemic index to postprandial glucose metabolism, insulin resistance, and cardiovascular risk factors. The World Health Organization and the Food and Agriculture Organization recommended that the physiological effects of dietary carbohydrates be classified according to their glycemic index. This review examines the historical and scientific background of the glycemic index.

Frost G, Wilkinson J, 2012, Compounds and their effects on appetite control and insulin sensitivity

Imperial innovations filed a UK priority patent application No1213629.7 entitled “compounds and their effects on appetite control and insulin sensitivity” in the name of Imperial Innovations and the University of Glasgow on the 31st of July 2012. We have filed a subsequent PCT application on the 31st of July 2013. The covers composition of matter and on a number of [novel prodrugs] or [propionate inulin esters] specifically designed to deliver short chain fatty acids to the gut. The patent also has claims directed to formulations and use in reduction of appetite/food intake/calorie intake. Claims are also directed and improving insulin sensitivity in a subject and for the treatment or prevention of diabetes or obesity.

The prevalence of obesity worldwide presents a great challenge to existing healthcare systems. There is a general need for pervasive monitoring of the dietary behaviour of those who are at risk of co-morbidities. Currently, however, there is no accurate method of assessing the nutritional intake of people in their home environment. Traditional methods require subjects to manually respond to questionnaires for analysis, which is subjective, prone to errors, and difficult to ensure consistency and compliance. In this paper, we present a wearable sensor platform that autonomously provides detailed information regarding a subject's dietary habits. The sensor consists of a microphone and a camera and is worn discretely on the ear. Sound features are extracted in real-time and if a chewing activity is classified, the camera captures a video sequence for further analysis. From this sequence, a number of key frames are extracted to represent important episodes during the course of a meal. Results show a high classification rate of chewing activities, and the visual log demonstrates a detailed overview of the subject's food intake that is difficult to quantify from manually-acquired food records. © 2012 IEEE.
