Tumors use protein recycling to grow

New study shows that tumor cells use protein recycling to fuel their growth.

A new research carried out on a variety of human tissues, suggests that recycling of protein in the body could be an important part of tumor formation.

According to the report published in Science Translational Medicine, researchers found that protein recycling was accelerated in more than 30 types of cancerous cell.

Scientists studied chaperone-mediated autophagy (CMA) which is a normal part of a cell’s routine and recycles the raw materials, the state-funded BBC reported.

Results showed that the level of CMA activity was higher in cancerous cells than normal ones.

The findings also demonstrated that cancerous cells use CMA process in order to fuel their abnormally rapid growth.

Scientists hope to develop an anticancer drug by finding a chemical that would interfere with the recycling process.
