The following antibodies were used in this study: mouse anti-Tuj1 (E10045BF; Covance, Princeton, USA), rabbit anti-PTEN (mAb#9559; Cell Signaling Technology, Beverly, USA),
chicken anti-GFP (A10262; Invitrogen, Carlsbad, USA),
mouse anti-β-actin (A5316; Sigma-Aldrich, St Louis, USA), and
mouse anti-GAPDH (glyceraldehyde-3-phosphate dehydrogenase) (AF1186, 1:2000; Beyotime, Shanghai, China) antibodies. The secondary antibodies include Alexa Fluor 488 or 568 and were purchased from Life Technology Molecular Probes, Inc. (Carlsbad, USA). The pAAV-CMV-Cre and pAAV-CMV-GFP virus vectors (titer 1.0×10
12) were purchased from the HANBIO Company (Shanghai, China). The mouse PTEN small interfering RNA (siRNA) mixture (siPTEN ON-TARGET plus) was purchased from Thermo Scientific Dharmacon (Chicago, USA). The sequences are 5′-UGAUGAUGUAGUAAGGUUU-3′, 5′-GCGCUAUGUAUAUUAUUAU-3′, 5′-GUAGUAGGCUCAAAUAUAC-3′, and 5′-GUUACAAGUUACAUGUUUA-3′. The microRNAs and
miR-26a inhibitors were purchased from GenePharma (Suzhou, China). The miR-26a sequence is 5′-UUCAAGUAAUCCAGGAUAGGCU-3′. The sequence of miR-26a inhibitor is complementary to miR-26a, 5′-AGCCUAUCCUGGAUUACUUGAA-3′.
