I whakawhanakehia e matou he punaha tuku RNA (siRNA) iti e pokanoa ana ma te whakamahi i te matatini ternary me te polyethyleneimine (PEI) me te waikawa γ-polyglutamic (γ-PGA), i whakaatu i te whakangao me te kore he cytotoxicity.Ko nga huinga takirua o te siRNA me te PEI he 73-102 nm te rahi o te matūriki me te 45-52 mV i te ζ-pumanawa.Ko te painga whakangau o nga matatini siRNA / PEI i piki ake me te piki o te PEI, a ko nga matatini siRNA / PEI me te tauwehenga utu nui ake i te 16 i whakaatu i te paheketanga nui o te luciferase i roto i te raina o te kiore kiore carcinoma cell line e whakaatu ana i te luciferase (Colon26 / Luc cells).Engari, ko te kaha o te cytotoxicity me te whakaheke toto i kitea i roto i te matatini siRNA / Lipofectamine me te siRNA / PEI16 matatini.Ko te whakakii i nga matatini cationic me te pūhui anionic i kiihia he huarahi pai mo te whakakore i enei paitini.Na reira i whakaritehia e matou nga taapiri o te siRNA me te PEI (te utu utu 16) ma te taapiri o te γ-PGA hei whakaiti i te cytotoxicity me te tuku siRNA.I te mea e tumanakohia ana, ka heke iho te cytotoxicity o nga matatini ternary me te piki ake o te ihirangi γ-PGA, i heke iho te ζ-potential o nga matatini.I kitea he awenga whakangau kaha e rite ana ki te matatini siRNA/Lipofectamine i roto i nga whare matatini tae atu ki te γ-PGA me te utu o te mata anionic.Ko te whakaurunga nui o nga matatini matua ki roto i nga pūtau Colon26/Luc i whakapumautia me te moroiti fluorescence.I te tutukitanga o te paheketanga o te ira kua whakawhitia i waho, ka aromatawaihia te kaha o te matatini ki te takawaenga i te paheketanga o te ira tiaki whare, glyceraldehyde 3-phosphate dehydrogenase (GAPDH), i aromatawaihia i roto i nga pūtau B16-F10.Ko te matatini ternary (siRNA / PEI16 / γ-PGA12 matatini) i whakaatu i te painga nui o te GAPDH knockdown.Na, i whakawhanakehia e matou he punaha tuku siRNA whai hua.
