The expression of FADS2 was also lower in the growing tumor area versus the peritumoral area and in the necrotic core versus the peritumoral area, but the difference was statistically significant only when using GAPDH as reference: FADS2 expression in the peritumoral area was 2 times higher than in the necrotic core (p = 0.027). Here, GAPDH is linked to neoplasm.
