Palmitate paves the way to lung metastasis

Abstract

New findings by Altea-Manzano et al. demonstrate that primary breast tumours or a high-fat diet induce palmitate secretion by alveolar type 2 (AT2) cells to prepare a premetastatic niche that promotes lung metastasis. Palmitate is utilised by cancer cells via carnitine palmitoyltransferase 1a (CPT1a) and lysine acetyltransferase 2a (KAT2a) to acetylate nuclear factor-κB (NF-κB)/p65. Blocking these enzymes reduced metastasis formation in both lean and high-fat diet mice.

Keywords: NF-kB; breast cancer; lung metastasis; palmitate; premetastatic niche; protein acetylation.
