NEAT1 and Parkinson disease: The observation that the two compounds both resulted in NEAT1 up-regulation, yet exerted opposing effects on the viability of cells prompted us to examine (a) if the opposite effects of NEAT1 up-regulation via SFN and MPP + can be recapitulated in vivo, (b) whether there is a difference in the expression of the two isoforms of the lncRNA and (c) if yes, how do the levels of Neat1 variants change in PSS and ESS MPTP models of PD.
