Moreover, gene expression of CD68 was decreased in all investigated cell fractions from tumor tissues (UICC stages I–III) when treated with KMP01D alone or in combination with vitamin D3 (KMP01D vs. untreated cells: UICC I–II: p < 0.0001; combination of KMP01D and vitamin D3 vs. untreated cells: UICC I–III: p < 0.0001). Here, CD68 is linked to neoplasm.
