Abstract
Bacteria carry a battery of multidrug transporters, which belong to six families of transporters. Members of at least three families the ATP-Binding Cassette superfamily, the Major Facilitator Superfamily and the Multidrug Endosomal Transporter family have been shown to contribute to multidrug resistance phenotype in eukaryotic cells. This review is focused on comparison of bacterial and eukaryotic transporters that do not have a common evolutionary trait and use different sources of energy to perform the transport. Yet they demonstrate an impressive resemblance. All multidrug transporters are capable of recognizing a broad spectrum of structurally diverse compounds. The accumulated data suggest that structural and mechanistic determinants of such ability are similar among unrelated proteins. Despite the apparent similarity, many features are still unique for different classes of transporters. Intriguingly, some cells appear to simultaneously express transporters belonging to different classes. Depen ding on mechanistic particularities of transporters such concurrent expression can result in synergistic or non-synergistic effects.

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
