The influence of HOXA5-specific siRNA on the expression of Livin and Smac proteins.
CONCLUSIONS: HOXA5-specific siRNA effectively silenced the HOXA5 gene expression and down-regulation of HOXA5 induced the down-regulation of Livin protein expression and up-regulation of Smac protein. We suggest the HOXA5 gene to be considered as the new target for acute leukemia gene therapy. PMID: 27460741 [PubMed - in process]

Hsp70 silencing with siRNA in nanocarriers enhances cancer cell death induced by the inhibitor of Hsp90.
The objective of this in vitro study was to silence inducible Hsp70 and to promote celastrol-induced tumor cell death. Hsp70 siRNA loaded chitosan-TPP carriers were prepared by ionic gelation and characterized by photon correlation spectroscopy and asymmetric flow field-flow fractionation combined with dynamic light scattering. Viability of human leukemia and glioblastoma cells and Hsp70 silencing was determined following treatment with chitosan-TPP-Hsp70 siRNA particles. The results showed that silencing of Hsp70 by chitosan-TPP-Hsp70 siRNA treatment significantly reduced cell viability, and enhanced antiproliferative eff...

Influence of controlled release of resveratrol from electrospun fibers in combination with siRNA on leukemia cells.
In this study, we evaluated the possibility of i) local release of resveratrol from poly(ε-caprolactone) (PCL) and gelatin (GT) electrospun fibers and ii) combining (i) with siRNA designed to downregulate BCR-ABL pathway on K562 cancer cells. Initially, K562 cell culture experiments were performed using various bolus doses of resveratrol in combination with siRNA for 3 days using a factorial design of experiments approach. Resveratrol content was analyzed using HPLC and cell viability was assessed using Annexin V (Non-viable), and Propidium Iodide (PI) (Necrotic) based flow cytometry. Coaxial electrospun fibers with res...

siRNA/Lipopolymer Nanoparticles to Arrest Growth of Chronic Myeloid Leukemia Cells In Vitro and In Vivo.
Abstract Therapies for the treatment of Chronic Myeloid Leukemia and other leukemias are still limited for patients at advanced stages, which allow development of point mutations in the BCR-ABL fusion gene that render CML cells insensitive to therapies. An effective non-viral delivery system based on lipopolymers is described in this study to deliver specific siRNAs to CML cells for therapeutic gene silencing. The lipopolymer, based on the lipid α-linolenic acid (αLA) substitution on low molecular weight polyethyleneimine (PEI), was used to deliver siRNA against the BCR-ABL gene and, the resultant therapeutic ef...

Current attempts to implement siRNA-based RNAi in leukemia models.
Abstract Leukemias arise from genetic alterations in normal hematopoietic stem or progenitor cells, leading to abnormal blood population with transformed cells. With the advent of RNAi and its pharmacological mediator siRNA, it has become possible to downregulate specific drivers causing leukemias. In this review, we present unique aspects of RNAi-mediated therapy and delivery technologies. Recent updates on molecular targets and delivery systems are discussed emanating from in vitro cell models and preclinical animal models. We conclude with a view on the future of RNAi in leukemia therapy, emphasizing possible m...

Effects of eEF1A1 targeting by aptamer/siRNA in chronic lymphocytic leukaemia cells
ConclusionsThe increase of eEF1A1 in dead vs surviving patients may confer to eEF1A1 the role of a prognostic marker for CLL and possibly of a therapeutic target, given its involvement in MEC-1 survival. Specific aptamer/siRNA released by optimized delivery systems may allow the development of novel therapeutic options.Graphical abstract

Non-canonical Notch Signaling Regulates Actin Remodeling in Cell Migration by Activating PI3K/AKT/Cdc42 Pathway
In conclusion, our research results indicate that DAPT activates PI3K/AKT/Cdc42 signaling by non-canonical Notch pathway, and the activated Cdc42 promotes the filopodia formation and inhibits lamellipodia assembly, resulting in reduced migration of breast cancer cells. The results imply that non-canonical Notch signaling may play a very important role in the rapid response of cells to the extracellular signals. Author Contributions LG, JD, and LL designed the study and wrote and revised the manuscript. LL and LZ performed most of the experiments and data analysis. SZ, X-YZ, P-XM, Y-DM, Y-YW, YC, S-JT, and Y-JZ assisted i...

Auranofin, an Anti-rheumatic Gold Drug, Aggravates the Radiation-Induced Acute Intestinal Injury in Mice
Conclusion In this study, we found that a non-toxic dose of auranofin significantly aggravated the severity of the radiation-induced intestinal injury. This suggests that auranofin treatment can be an independent factor that influences the risk of intestinal complications after pelvic or abdominal radiotherapy. Ethics Statement All the protocols used in this study were approved by the Institutional Animal Care and Use Committee of the Korean Institute of Radiological and Medical Sciences (IACUC permit number: KIRAMS217-0007). Author Contributions H-JL, JS, and Y-BL designed the experiments. EL and JK conducted the exp...

Knockdown of PRAME enhances adriamycin-induced apoptosis in chronic myeloid leukemia cells.
CONCLUSIONS: PRAME is responsible for the inherent low levels of spontaneous apoptosis in K562 cells. The combination of PRAME siRNA with ADR induced more intense apoptosis compared with each single treatment. PRAME siRNA in combination with ADR is well tolerated and shows greater efficacy than either agent alone in mouse xenograft models. PMID: 26744874 [PubMed - in process]

Suppression of protein tyrosine phosphatase PTPN22 gene induces apoptosis in T-cell leukemia cell line (Jurkat) through the AKT and ERK pathways
In this study, Jurkat cells were transfected with specific PTPN22 siRNA. Relative PTPN22 mRNA expression was measured by Quantitative Real-time PCR. Western blotting was performed to determine the protein levels of PTPN22, AKT, P-AKT, ERK, and P-ERK. The cytotoxic effects of PTPN22 siRNA were determined using the MTT assay. Apoptosis was quantified using TUNEL assay and flow cytometry. Results showed that in Jurkat cells after transfection with PTPN22 siRNA, the expression of PTPN22 in both mRNA and protein levels was effectively reduced. Moreover, siRNA transfection induced apoptosis on the viability of T-cell acute leuke...
