[Abstract]ObjectiveToinvestigate theefectofacyl-CoA synthetaselong-chain family member4（ACSL4）onmitochondrial number in N2a cells after1-methyl-4-phenylpyridinium （ .MPP+ ）treatment. MethodsWestern blotting was used to measure the protein expression level of ACSL4 in N2a cells after MPP+ treatment. N2a cels were transfected with Flag-Vector or FlagACSL4 plasmids，and Westernbloting wasused toobservethe efect of ACSL4overexpressonontheexpressonlevelsofvoltage dependentanionchanel1（VDAC1）and mitochondrial import receptor subunit TOM20 homolog（TOMM2o）in N2acels after （20號(hào) MPP+ treatment. ResultsCompared with the control group，the MPP+ treatment group had a significant increase in the protein expression level of ACSL4 in N2a cells Ω′t=3.965，P<0.05） . Compared with the control group，the MPP+ treatment group had significant increases in the expresson levels of VDAC1 and TOMM20 （ F=28.59，15.15，P<0.01） ，while compared with the MPP+ treatment group，ACSL4 overexpression had no further impact on the expresson levels of VDAC1 and TOMM20 in N2a （204號(hào) cells （P>0.05 ）.ConclusionACSL4 overexpression has no impact on mitochondrial number in N2a cells after MPP+ treatment，sugestingthattheroleof ACSL4inthepathogenesisofParkinson’sdiseasedoes not involveitsimpactonmitochondrial number.
