“Following validation assays of possible screen “hits” using the MTS assay, we identified the cytosine nucleoside-analog DNA methyltransferase (DNMT) inhibitor decitabine, as the most effective drug in our mutant Htt neuroprotection screen (Fig. 1B and S1A).”

“Although FdCyd when tested structurally similar to decitabine, we found that, whereas decitabine lost its in vitro neuroprotective activity after 11 days of pre-incubation at 37 °C in saline, FdCyd fully maintained its neuroprotective activity even after 45 days of pre-incubation (Figure S6A,B), suggesting that FdCyd is chemically more stable than decitabine at 37 °C in vitro and is better suited for drug delivery with osmotic pumps.”

“Images of Alexa Fluor 568-labeled were captured (nine random fields per well) using an Operetta high-content imaging system (PerkinElmer) with a 20 × objective lens. Following image background subtraction, the NF immunofluorescence intensity was quantified using an ImageJ-based macro.”
