ABSTRACT
OBJECTIVE@#To investigate the effect of bone marrow stromal cell glycosyltransferase B4GALT1 expression on hematopoietic cell proliferation and its upstream regulation mechanism.@*METHODS@#B4GALT1 was overexpressed in human bone marrow stromal cell line HS5, which was then co-cultured with acute myeloid leukemia cell line KG1a. And its effect on hematopoietic cell proliferation was detected by flow cytometry. Dual luciferase reporter assay, real-time PCR and Western blot were used to predict and validate upstream transcription factors that regulate stromal cell B4GALT1 expression.@*RESULTS@#Overexpression of B4GALT1 in HS5 significantly promoted the proliferation of KG1a in the co-culture system. B4GALT1 expression in stromal cells positively correlated with upstream c-Jun expression, which was verified by JNK/c-Jun inhibitors.@*CONCLUSION@#The differential expression of glycosyltransferases and their corresponding glycosylation in the hematopoietic microenvironment play an important role.
