Ka taea e te Niacin (waikawa nikotinic) te whakamaarama kotahi te whakaiti i te tupono ki te mate ngongo, engari ka tautohetohe tonu tana tikanga mahi, a kare pea i te whakawhirinaki ki nga paanga whakarereke lipid punaha.Ko te Niacin i whakaatu tata nei ki te whakapai ake i te mahi endothelial me te whakahou i te toto, motuhake mai i te whakatika i te dyslipidemia, i roto i nga tauira kiore o te whara me te mate metabolic.I te mea ko te tuupapa koiora mo te NAD(+), ka taea e te niacin te whakaputa i enei painga toto ma te NAD(+)-whakaaro, sirtuin (SIRT) whakautu takawaenga.I tua atu, ka taea e te niacin te mahi na roto i tana kaiwhiwhi, GPR109A, ki te whakatairanga i te mahi endothelial, ahakoa kaore i te mohiotia nga pūtau endothelial ki te whakaatu i tenei kaiwhiwhi.I whakapae matou ko te niacin te whakapai ake i te mahi o nga pūtau endothelial i te wa e pa ana ki nga ahuatanga lipotoxic me te rapu ki te whakatau i nga tikanga ka uru mai. Ko te mahi angiogenic i roto i te nui o te palmitate i aromatawaihia e te hanganga ngongo i muri i te maimoatanga o nga pūtau endothelial microvascular tangata (HMVE C) me te a he iti noa te kukū o te niacin (10 μM), ranei nicotinamide mononucleotide (NMN) (1 μM), he NAD tika (+) tomua.Ahakoa ko te niacin me te NMN i pai ake te hanga ngongo HMVEC i te wa o te nui o te palmitate, ko te NMN anake i piki ake te mahi NAD (+) me te SIRT1.I kite ano matou ko HMVEC te whakaputa GRP109A.Ko te whakahohenga o tenei kaiwhakawhiwhi me te acifran, MK-1903 ranei te whakahou i nga whakapainga a te niacin i roto i te hanga ngongo HMVEC, i te GPR109A siRNA i whakaiti i te painga o te niacin.Niacin, i te iti o te kukū, ka whakapai ake i te mahi angiogenic HMVEC i raro i nga tikanga lipotoxic, he mea motuhake mai i te NAD( +) biosynthesis me te whakahohe SIRT1, engari na roto i te whakahohenga kaiwhiwhi niacin.
