Thwarting PTEN expression by siRNA, augments HL-60 cell differentiation to neutrophil-like cells by
DMSO and ATRA and reduces NETosis

Abnormal cell differentiation in particular suppression of terminal cell differentiation, exist in all tumors. Therapeutic intervention
to restore terminal differentiation (differentiation therapy) is a very attractive way to treat cancer, especially leukemia. A variety
of chemicals stimulates differentiation of leukemic cells such as dimethyl sulfoxide (DMSO) and all-trans retinoic acid (ATRA).
Tumor suppressor genes have a vital role in the gateway to terminal cell differentiation. In this study we inhibited PTEN tumor
suppressor gene expression by siRNA to investigate the effect of potentiating cell survival and inhibiting apoptosis on HL-60 cell
differentiation by DMSO and ATRA at the same time we looked at NETosis. Our results show that PTEN siRNA increases HL-60 cell
differentiation in the presence of DMSO and ATRA. At the same time the presence of siRNA hampered accumulation of apoptotic
cells during incubation. PTEN siRNA reduced Net formation by differentiated neutrophils. Our study suggests potential usage of
differentiation therapy in PTEN mutated AML leukemia.
