Fars2 depletion affects neurite outgrowth in primary cultured neurons and zebrafish motor neurons. A Immunofluorescence staining of primary cultured neurons at the indicated day of culture. Neurons were infected with lentivirus carrying mcherry (red), the neurites were labeled with MAP2 (green) and the nucleus with DAPI (blue). Scale bars: 20 μm. B Quantification of the longest neurite length at the indicated days (mean ± SD; two-tailed unpaired t-Test, ns: non-significant; ****P < 0.0001; n = 60). CD Sholl analysis of control and Fars2 knocked-down neurons at the 8th day of culture (mean ± SD; two-tailed unpaired t-Test, *P < 0.5; **P < 0.01; n = 6). E Immunofluorescence staining of neurons at 8 days post-infection. Neurons were infected with lentivirus carrying mcherry (red), the neurites were labeled with MAP2 (green) and the nucleus with DAPI (blue). Arrowheads point to the fracture of axons. Scale bars: 50 μm. F TUNEL staining of control and Fars2 knocked-down neurons at the indicated days of culture. G Western blotting for Caspase 3 and Cleaved-caspase 3 in control and Fars2 knocked-down neurons at the indicated days in culture
