SIRT1 Inhibits Apoptosis by Promoting Autophagic Flux in Human Nucleus Pulposus Cells in the Key Stage of Degeneration via ERK Signal Pathway

Figure 2

Western blot analysis of LC3II/I and p62 expression in NP cells from the grade I, III(NH), and V groups. The relative protein expression of LC3II/I corresponds to the ratio of LC3II signal to LC3I signal, and p62 corresponds to the ratio of p62 signal to β-actin signal. The values are shown as the of three independent experiments performed in triplicate. , . NH: normal height.
