gamma (NSG) mice (Jackson Laboratory, Sacramento, CA, USA) were randomly divided
into 2 groups and transplanted intravenously with CCRF-CEM-FFluc cells (5 mice
in control group: pCDH empty vector lentivirus infected; 5 mice in miR-26b
overexpressed group: pCDH-miR-26b lentivirus infected). The engraftment of
CCRF-CEM-FFluc was monitored by flow cytometry (anti-human CD45-APC antibody (BD
Biosciences, San Jose, CA, USA) and GFP on mouse retro-orbital bleeding samples.
Phospho-AKT was measured by intracellular staining flow cytometry (Cell
Signaling; #11962) on mixed mouse retro-orbital bleeding samples.
Transplanted mice underwent in vivo bioluminescence imaging at
various time points. The mice in each group were followed for survival. 2 groups
of the mice were treated and experimented under the same condition. This study
was approved by Institutional Review Board (IRB) the University of Texas MD
Anderson Cancer Center.
