Theoretical framework and emerging challenges of lipid metabolism in cancer.

Elevated lipid metabolism is one of hallmarks of malignant tumors. Lipids not only serve as essential structural components of biological membranes but also provide energy and substrates for the proliferation of cancer cells and tumor growth. Cancer cells meet their lipid needs by coordinating the processes of lipid absorption, synthesis, transport, storage, and catabolism.

Targeting SMOX for the treatment of hepatocellular carcinoma?

Dysregulation of the polyamine metabolism is common in different cancer types. SMOX is upregulated in hepatocellular carcinoma (HCC) but the relationship between SMOX and liver inflammation and fibrosis, remains unclear. In this issue of Clin Res Hepatol Gastroenterol, Hu and colleagues find targeting SMOX can alleviate liver cancer progression.
