Design
Laboratory study
Subjects
Human triple-negative breast cancer cells (MDA-MB-231 and MDA-MB-BrM2) and mice given MDA-MB-BrM2 cells
Dose used in the study
Palmitoylethanolamide or the NAAA inhibitor AM11095 in cell culture; AM11095 in mice; doses not stated in the abstract
Duration
Not stated in the abstract
What was measured
NAAA expression; IL-6 and IL-8 secretion, NF-kB activation, VEGF and PLGF expression and cell migration; tumour number, volume and survival in mice by MRI.

What the authors reported

This lab study found:

  • Cancer cells expressed raised NAAA.
  • PEA or AM11095 reduced IL-6 and IL-8 secretion, NF-kB activation, VEGF and PLGF expression and cell migration.
  • Mice treated with AM11095 had fewer and smaller tumours and longer survival than untreated or vehicle-treated mice.

Limits of this study

A cell and mouse study; it cannot show effect in people or animals treated in practice. The in vivo results used the NAAA inhibitor, not PEA itself. The authors declare no competing interests.
