All-trans retinoic acid (ATRA) induces granulocytic differentiation and apoptosis in acute promyelocytic leukemia (APL) cells, although the detailed mechanisms are not fully understood. We investigated ATRA-induced cellular responses mediated by the transcription factor FOXO3A in APL cells. FOXO3A was constitutively phosphorylated and localized in the cytoplasm in both APL-derived NB4 cells and primary APL cells. Upon treating the cells with ATRA, FOXO3A phosphorylation was reduced and FOXO3A…

Lentivirus-mediated RIG-I knockdown relieves cell proliferation inhibition, cell cycle arrest and apoptosis in ATRA-induced NB4 cells via the AKT-FOXO3A signaling pathway in vitro

Investigations showed that the knockdown of RIG-I reduced the inhibition of cell proliferation, cell cycle arrest and apoptosis in the ATRA-induced NB4 cells via the AKT-FOXO3A signaling pathway.

Selenite promotes all-trans retinoic acid-induced maturation of acute promyelocytic leukemia cells

It is shown that selenite at clinically achievable dose targets PML/RARα oncoprotein for degradation and potentiates differentiation of promyelocytic leukemic cells in combination with ATRA.

Retinoids induce antagonism between FOXO3A and FOXM1 transcription factors in human oral squamous cell carcinoma (OSCC) cells

Novel influences of the drugs RA and bexarotene on the expression of FOXM1 and FOXO3A in transcriptional regulatory pathways of human OSCC are suggested.

HOX antisense lincRNA HOXA‐AS2 is an apoptosis repressor in all Trans retinoic acid treated NB4 promyelocytic leukemia cells

It is demonstrated that ATRA induction of HOXA‐AS2 suppresses ATRA‐induced apoptosis, possibly through a TRAIL‐mediated pathway, and contributes to the fine‐tuning of apoptosis during ATRA-induced myeloid differentiation in NB4 cells.

All-Trans Retinoic Acid Promotes TGF-β-Induced Tregs via Histone Modification but Not DNA Demethylation on Foxp3 Gene Locus

The cellular and molecular mechanism(s) by which atRA promotes the development and maintenance of iTregs are identified and may provide novel insights into clinical cell therapy for patients with autoimmune diseases and those needing organ transplantation.

A FOXO1-induced oncogenic network defines the AML1-ETO pre-leukemic program Running title: FOXO1 is an oncogenic mediator in AML1-ETO leukemia Scientific category: Myeloid Neoplasia

Targeting of FOXO1 provides a potential therapeutic strategy for elimination of stem cells at both pre-leukemic and leukemic stages and prevents acute myeloid leukemia (AML) relapse.

Novel Agent Nitidine Chloride Induces Erythroid Differentiation and Apoptosis in CML Cells through c-Myc-miRNAs Axis

It is suggested that NC promoted erythroid differentiation and apoptosis through c-Myc-miRNAs regulatory axis, providing potential possibility to overcome imatinib resistance.

Unregulated miR-96 Induces Cell Proliferation in Human Breast Cancer by Downregulating Transcriptional Factor FOXO3a

It is suggested that miR-96 may play an important role in promoting proliferation of human breast cancer cells and present a novel mechanism of miRNA-mediated direct suppression of FOXO3a expression in cancer cells.



Ionizing radiation activates expression of FOXO3a, Fas ligand, and Bim, and induces cell apoptosis.

It is shown that ionizing radiation can promote FOXO3a (FKHRL1) transcriptional activity and protein expression level, and induce nuclear translocation of FOXO 3a in Saos2, a p53-null osteosarcoma cell line, and suggest a novel p 53-independent mechanism underlying ionizing Radiation-induced apoptosis in cancer cells.

Pml is essential for multiple apoptotic pathways

It is demonstrated that Pml is a mediator of multiple apoptotic signals, and implicate inhibition of apoptosis in the pathogenesis of APL.

Cytokines and BCR-ABL mediate suppression of TRAIL-induced apoptosis through inhibition of forkhead FOXO3a transcription factor

It is demonstrated that hematopoietic cytokines such as IL-3 and erythropoietin in normal cells, as well as BCR-ABL oncoprotein in transformed cells, inhibit transcription of tumor necrosis factor-related apoptosis-inducing ligand (TRAIL).

Mutant AF-2 domain of PML-RARα in retinoic acid-resistant NB4 cells: differentiation induced by RA is triggered directly through PML-RARα and its down-regulation in acute promyelocytic leukemia

The data suggest that differentiation of APL by RA is triggered directly through PML-RARα, and is associated with its degradation, and there might be another mechanism of differentiation which does not require the down-regulation of PML -RAR α and the restoration of thePML-staining pattern.

Retinoic acid-induced apoptosis in leukemia cells is mediated by paracrine action of tumor-selective death ligand TRAIL

Induction of TRAIL-mediated death signaling appears to contribute to the therapeutic value of retinoids in the leukemic blasts of freshly diagnosed acute promyelocytic leukemia patients.

Active FKHRL1 overcomes imatinib resistance in chronic myelogenous leukemia‐derived cell lines via the production of tumor necrosis factor‐related apoptosis‐inducing ligand

Results suggest that active FKHRL1 can overcome imatinib resistance in CML cells, in part via TRAIL production.

FOXO3a mediates the cytotoxic effects of cisplatin in colon cancer cells

The findings suggest that FOXO3a is a relevant mediator of the cytotoxic effects of cisplatin in colon cancer cells, and the phosphoinositide-3-kinase/protein kinase B/FOXO signaling axis modulators triciribine and psammaplysene A sensitize the resistant HT29 cells to cisPlatin treatment.

Constitutive activation of Akt by Flt3 internal tandem duplications is necessary for increased survival, proliferation, and myeloid transformation.

It is shown that the presence of Flt3-ITD constitutively activates Akt (PKB), a key serine-threonine kinase within the phosphatidylinositol 3-kinase pathway, which indicates that Akt and Foxo transcription factors are attractive targets for therapeutic intervention in AML.

The transcription factor FOXO3a is a crucial cellular target of gefitinib (Iressa) in breast cancer cells

The results suggest that the FOXO3a dephosphorylation and nuclear localization have a direct role in mediating the gefitinib-induced proliferative arrest and in determining sensitivity to gef itinib.
