New myeloma-obesity research shows drugs can team with body's defenses
Date:5/2/2014

tion abnormally, including producing less adiponectin. What they produce more of, however, are fatty acids, and it is likely that myeloma cells can feed on these fatty acids.

"Synthesizing fatty acids is important for myeloma cells to build vital structures, including cell membranes, that enable them to keep on growing," Medina said.

Focusing on adiponectin led Dr. Medina's lab to protein kinase A or "PKA" a protein that, when activated by adiponectin, suppresses the fatty acids that myeloma cells need, leading to their demise.

The idea is to use the understanding of the pathways that adiponectin uses to kill myeloma cells to create a drug that would do the same thing.

"If we could pharmacologically suppress these fatty acid levels in obese myeloma patients, we could boost the effects of the chemotherapy that targets PKA or fatty acid synthesis, and potentially decrease the chemotherapeutic dose," Medina said. "Also, it would give your own body's protective measures more of a chance to work against the cancer."
