Breast cancer is the most common and the second-most fatal malignant tumour amongst women who live in industrialised countries. Moreover, when present in young women, it would appear that a genetic predisposition is involved. This predisposition can be due to a number of causes and, amongst the most common, lie the alterations in the gene suppressors of the tumours. The lack of efficiency in these genes may be due to the fact that they are altered (mutated), they are not expressed, or they do not function because their start-up system (methylation) is altered, or a fragment is missing (deletion).
Mutations of specific gene suppressors (Brca1, Bcra2, ATM; Che2...), which in principle might be thought to be of great use in the clinic, are much more frequent than previously thought and, moreover, difficult to detect in many occasions. This is why, in clinical applications, more general markers to help in the prognosis of early breast cancer development are sought. These markers would indicate, for example, which patients need chemotherapy and which do not.

Proteins must be folded correctly to fulfill their molecular functions in cells. Molecular assistants called chaperones help proteins exploit their inbuilt folding potential and reach the correct three-dimensional structure. Researchers at the Max Planck Institute of Biochemistry (MPIB) have demonstrated that actin, the most abundant protein in higher developed cells, does not have the inbuilt potential to fold and instead requires special assistance to fold into its active state. The chaperone TRiC uses a previously undescribed mechanism to perform actin folding. The study was recently published in the journal Cell.
Actin is the most abundant protein in highly developed cells and has diverse functions in processes like cell stabilization, cell division and muscle...
