Anti-microRNA103/107 (5′-rUrCrArUrArGrCrCrCrUrGrUrArCrArArUrGrCrUrGrCrU-3′) and (5′-/5RhoR-XN/rUrCrArUrArGrCrCrCrUrGrUrArCrArArUrGrCrUrGrCrU-3′), namely anti-miR103/107, was synthesized by Tema Ricerca s.r.l. (Bologna, Italy). 1,2-dioleyl-3-dimethylammonium propane (DODAP), N-palmitoyl-sphingosine-1-succinyl[methoxy(polyethylene glycol)2000] (PEG2000-Cer16) and 1,2-distearoyl-sn-glycero-3-phosphoethanolamine-N-[amino(polyethylene glycol)-2000]-Maleimide (DSPE-PEG-Mal) and 1,2-dioleoyl-sn-glycero-3-phosphoethanolamine-N-(carboxyfluorescein) (ammonium salt) were obtained by Avanti Polar Lipids. Disteroylphosphatidylcholine (DSPC) was kindly offered from Lipoid GmbH (Cam, Switzerland). Cholesterol (CHOL), human transferrin (Tf), ammonium ferrithiocyanate, sodium borate, sodium chloride, sodium citrate, sodium phosphate, HEPES, ethylenediaminetetraacetic acid (EDTA), citric acid, Sepharose G-25, and 2-iminothiolane (Traut’s reagent) were purchased from Sigma-Aldrich (USA). Ethanol and other solvents were obtained by Exacta Optech (Italy).
