SK-N-SH cells were exposed to 1-methyl-4-phenylpyridinium (MPP+) to mimic PD model in vitro. The levels of HOTAIR, miR-874-5p and autophagy-related 10 (ATG10) were determined by quantitative real-time polymerase chain reaction (qRT-PCR) or western blot assay. Here, ATG10 is linked to Parkinson disease.
