UCLA study shows tumors are not as addicted to glucose as previously thought

Scientists at the Eli and Edythe Broad Center of Regenerative Medicine and Stem Cell Research at UCLA have discovered that squamous cell skin cancers do not require increased glucose to power their development and growth, contrary to a long-held belief about cancer metabolism.

The findings could lead to a better understanding of the metabolic needs of many different types of cancer, and to the development of new cancer treatments. The research, led by senior authors Heather Christofk and Bill Lowry, was published in the journal Nature Communications.

"These findings suggest that tumors are metabolically flexible and can use nutrients other than glucose to fuel growth," said Heather Christofk, a senior author of the study and a UCLA associate professor of biological chemistry and of molecular and medical pharmacology. "Understanding all of the nutrients cancers use for growth is critical to developing drugs that can successfully target cancer's metabolism."
