Dexamethasone (Dex)-treated B lymphoma tissues have a higher level of SARI.
Dex represses the growth of B lymphoma cells in vitro and in vivo.
Dex upregulates SARI expression via activating glucocorticoid receptor (GR).
GR directly binds to the ER9 element (−178 to −158) in SARI promoter region.
SARI induction plays an important role in Dex's killing effect on B lymphoma cells.
