Mayo Clinic researchers are the first to identify an interaction between two cellular proteins -- Skp2 and FOXO1 -- that is important for the growth and survival of cancer cells. Researchers also show that this interaction can be chemically reversed to stop cancer tumor growth -- a strategy that may lead to new and better cancer treatments.
Their report appears as an electronic advance article of PNAS, the Proceedings of the National Academy of Sciences ( http://www.pnas.org/cgi/reprint/102/5/1649). The research was performed on human cells in the laboratory and was found effective against human cancer cells. Researchers say it will be at least a year before the discovery can be applied in a human clinical trial.
The researchers noted that high levels of Skp2 were associated with low levels of FOXO1 in many human cancer cells, including prostate cancer -- and then combined the lines of evidence outlined above to design experiments to answer the specific question: Do elevated levels of Skp2 drive down and disable FOXO1, thus resulting in loss of its tumor suppression ability? The answer is yes.

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...
