Researchers have uncovered a significant contributing factor to interferon resistance of malignant melanoma cells. The finding represents a step forward in understanding the molecular events that govern the growth of this type of cancer and the changes in gene expression and cellular signaling that underlie resistance to established therapies.
Malignant melanoma is the deadliest form of skin cancer, and if not treated successfully, it can spread to affect the liver, lungs, or brain. Chemotherapy fights the disease with limited efficiency, and the use of interferon has become the most established immunotherapy for advanced-stage melanoma. However, melanoma tumors often develop a resistance to the drug, posing one of the major obstacles in the clinical treatment of this cancer.
Now Professor Manfred Schartl and Dr. Claudia Wellbrock, scientists at the University of Würzburg, believe they have an explanation for how this interferon resistance is acquired. They have found that when a gene called STAT5 is too active in melanoma cells, it can counteract the anti-cancer effect of interferon. Interferon normally impedes the growth of cancer cells, whereas STAT5 is thought to act to promote cellular growth.

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...
