ABSTRACT
Objective To investigate the expression of SP 100 protein in ATRA-treated NB4 cells and its effect on pro-liferation in NB4 cells.Methods Q-PCR was employed to measure the expression of SP 100 mRNA;Western blot was used to detect the expression of SP 100 protein; Immunofluorescence was adopted to determine the location of SP100;Cell viability was analyzed by CCK 8;Flow cytometry was used for cell cycle analysis .Results ATRA may induce the expression of mRNA and protein of SP 100.ATRA changes the location of SP100 from a micro-punctate pattern into a punctate nuclear pattern in NB 4 cells.SP100-shRNA promotes the proliferation of NB 4 cells and in-creased the cells in G2/M phase.Conclusions The expression of SP100 was significantly increased in ATRA-treated NB4 cells, and SP100 may be involved in the regulation of proliferation activity of NB 4 cells.
