Pemetrexed (folic acid metabolism inhibitor) effect. PTX (0.25–20 μM, low dose effect; 125 μM–2.5 mM, high dose effect) cell proliferations were measured in real time for 7 h. A nontoxic dose was selected for HUVECs for combined effect. When the trend change between recurrent measurements was analyzed using Mauchly’s sphericity test, the 5 and 2.5 mM PTX groups were significantly higher than the control group (P < 0.05).
