NHF were treated with vehicle, 1 μM of TOP-N53, 100 μM of Sildenafil, and/or 40 mg/L of uric acid for 24 h and supplemented with 2.5 nM of ConA (2 h) when indicated. RNA was isolated with
RNeasy Mini kit (Qiagen, Hilden, Germany) following the manufacturer’s guidelines. Reverse transcription was performed with
Quantitect RT kit (Qiagen, Hilden, Germany), using 400 ng RNA as starting material. Quantitative PCR was then performed using the
KAPA SYBR Fast (Universal) qPCR kit (Merck Millipore, Burlington, MA, USA) according to the manufacturer’s recommendations. The qRT PCR reaction was performed with a
Rotor-GeneQ (Qiagen, Hilden, Germany) and the same thermal profile conditions were used for all primer sets: 95 °C for 10 min; then 40 cycles were performed of 10 s at 95 °C, 20 s 60 °C, and 20 s 72 °C. The following primer pairs were used:
HPRT1 forward 5′-TGA CAC TGG CAA AAC AAT GCA-3′;
HPRT1 reverse 5′-GGT CCT TTT CAC CAG CAA GCT-3′;
P62 forward 5′-CAT CGG AGG ATC CGA GTG TG-3′; and
P62 reverse 5′-TTC TTT TCC CTC CGT GCT CC-3′.
