Abstract
Bowman-Birk inhibitors and their variants (BBI) from legumes, such as soybean, pea, lentil and chickpea, are a class of naturally-occurring protease inhibitors which have potential health-promoting properties within the gastrointestinal tract. BBI can resist both acidic conditions and the action of proteolytic enzymes, and transit through the stomach and small intestine without major degradation, permitting significant amounts to reach the large intestine in active form to exert their reported anti-carcinogenic and anti-inflammatory properties. These potential pharmacological benefits have been linked recently to the intrinsic ability of BBI to inhibit serine proteases, and the data suggest that both trypsin- and chymotrypsin- like proteases involved in carcinogenesis should be considered as potential targets of BBI. However, the therapeutic targets and the action mechanisms of BBI remain unknown. Their elucidation will provide insights into the properties of these plant protease inhibitors as colorectal chemopreventive agents, providing a strong base for the development of legume crops and their products as pro-nutritional, health-promoting food. The deployment of modern genomic tools and genome sequence information are underpinning studies of natural and induced polymorphism in BBI. Genetic markers for BBI variants with improved properties can be exploited ultimately in legume breeding programmes to assist the introgression of such variant genes and the development of superior genotypes for human nutrition.

Nutrition and Metabolism in Musculoskeletal Diseases
The musculoskeletal system consists mainly of cartilage, bone, muscles, tendons, connective tissue and ligaments. Balanced metabolism is of vital importance for the homeostasis of the musculoskeletal system. A series of musculoskeletal diseases (for example, sarcopenia, osteoporosis) are resulted from the dysregulated metabolism of the musculoskeletal system. Furthermore, metabolic diseases (such ...read more
Protein Folding, Aggregation and Liquid-Liquid Phase Separation
Protein folding, misfolding and aggregation remain one of the main problems of interdisciplinary science not only because many questions are still open, but also because they are important from the point of view of practical application. Protein aggregation and formation of fibrillar structures, for example, is a hallmark of a ...read more
