Abstract
Cohesin complexes are critical for holding sister chromatids together during nuclear division. They also play important roles in the compaction of chromosomes and their bipolar attachment to the spindle, DNA double strand break repair, and the regulation of gene expression. Studies on sister chromatid cohesion in a wide range of organisms have shown that the proteins involved, and the general events of this important process are conserved between yeast, plants and animals. However, species-specific differences have been identified. In this review a general overview of cohesins, their roles-and mechanisms of action is presented, followed by a review of our current state of knowledge on plant cohesins. While plants utilize the same general set of cohesin proteins and similar processes to establish and release sister chromatid cohesion, they also exhibit a number of unique features that are likely to provide interesting new insights into the roles of these important proteins.

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
