Hormone That Protects Women From Liver Cancer
Researchers have discovered that a hormone - present at higher levels in women - can keep them away from liver cancer, suggesting the disease is more common in men. The study showed that a potential contributor to this gender disparity is adiponectin, a hormone secreted by fat cells that helps control the body's metabolism.
The hormone activates two proteins inside liver cells, known as p38 and AMPK, that block cell proliferation and impair tumour growth, said the study, published in the Journal of Experimental Medicine.
Similar to humans, male mice are more also prone to hepatocellular carcinoma (HCC) - the most common form of liver cancer -than females, as the increased levels of adiponectin in female mice protect them from HCC, the study said.
Inhibiting testosterone production in male rodents increased their adiponectin levels and reduced tumour growth. Importantly, the study suggested that adiponectin and metformin - a common antidiabetic drug - could be used as novel treatments for liver cancer.
