Abstract
Sox2 and Oct4 dysregulations could significantly increase in the cancer stem cell (CSC) population in some cancer cells and resistance to common treatments. In this study, the synergistic effects of Sox2-Oct4 decoy oligodeoxynucleotides-encapsulated Niosomes-zinc hybrid nanocarriers along with X-irradiation conditions as a combinational therapy tool were investigated in the treatment of cancer-like stem cells (NTERA-2). The NTERA-2 cell line known as a cancer-like stem cell line was used in this investigation. Sox2-Oct4 decoy oligodeoxynucleotides were designed based on the sequence of the Sox2 promoter and synthesized. Physicochemical characteristics of ODNs-encapsulated niosomes-zinc hybrid nanocarriers (NISM@BSA-DEC-Zn) investigated with FT-IR, DLS, FESEM, and ODNs release kinetic estimation assays. Further investigations such as hemolysis, uptake, cell viability, apoptosis, cell cycle, and scratch repair tests were performed. All the above assays were completed with and without X-ray exposure conditions (fractionated 2Gy). Physicochemical characteristics results showed that the Niosomes-Zn nanocarriers were successfully synthesized. NISM@BSA-DEC-Zn was efficiently taken up by NTERA-2 cells and significantly inhibited cell growth, increased apoptosis, and reduced cell migration in both conditions (with and without X-ray exposure). Furthermore, NISM@BSA-DEC-Zn treatment resulted in G1 and G2/M cell cycle arrest without and with X-irradiation, respectively. The prepared nanocarrier system can be a promising tool for drug delivery in cancer treatment. Decoy ODN strategy along with zinc nanoparticles could increase the sensitivity of cancer cells toward irradiation, which has the potential for combinational cancer therapies.

Abstract
The main treatment modalities for breast cancer include surgery, chemotherapy, and radiotherapy, and each treatment will bring different side effects. Design and synthesizing a novel nanostructure for chemo-radiotherapy has been proposed as an effective method in consideration to enhance the drug efficiency as well as improve the effect of radiotherapy. This study aimed to synthesize zinc nanoparticles (ZnNPs) coated with alginate conjugated with Doxorubicin (Dox) drug and investigate its effects along with X-irradiation on MDA-MB-231 triple-negative breast cancer cell line. ZnNPs coated with alginate were synthesized and conjugated to Dox by covalent bonding and characterized using various physicochemical tests. A hemolysis test was used to assess blood biocompatibility. The radiosensitization properties and anti-cancer effects of the synthesized nanostructures were tested by cell uptake, cell viability, apoptosis, cell cycle, and scratch assays with and without radiation exposure. The physicochemical characterization results showed that the synthesis of nanostructures was successfully carried out. The obtained results from the cell uptake assay showed the effective absorption of nanostructures by the cells. The Zn@Alg-Dox NPs significantly reduced cell growth, increased apoptosis, inhibited cell migration, and led to the arrest of different cell cycle phases in both conditions with and without X-ray exposure. Coating ZnNPs with alginate and Doxorubicin conjugation leads to an increase the radiation sensitivity in radiotherapy as well as therapeutic efficiency. Therefore, Zn@Alg-Dox NPs can be used as radiosensitizing nanomedicine for in vivo studies in the future.

Abstract
BACKGROUND An increase in cancer stem cell (CSC) populations and their resistance to common treatments could be a result of c-Myc dysregulations in certain cancer cells. In the current study, we investigated anticancer effects of c-Myc decoy ODNs loaded-poly (methacrylic acid-co-diallyl dimethyl ammonium chloride) (PMA-DDA)-coated silica nanoparticles as carriers on cancer-like stem cells (NTERA-2). METHODS AND RESULTS The physicochemical characteristics of the synthesized nanocomposites (SiO2@PMA-DDA-DEC) were analyzed using FT-IR, DLS, and SEM techniques. UV-Vis spectrophotometer was applied to analyze the release pattern of decoy ODNs from the nanocomposite. Furthermore, uptake, cell viability, apoptosis, and cell cycle assays were used to investigate the anticancer effects of nanocomposites loaded with c-Myc decoy ODNs on NTERA-2 cancer cells. The results of physicochemical analytics demonstrated that SiO2@PMA-DDA-DEC nanocomposites were successfully synthesized. The prepared nanocomposites were taken up by NTERA-2 cells with high efficiency, and could effectively inhibit cell growth and increase apoptosis rate in the treated cells compared to the control group. Moreover, SiO2@PMA-DDA nanocomposites loaded with c-Myc decoy ODNs induced cell cycle arrest at the G0/G1 phase in the treated cells. CONCLUSIONS The conclusion drawn from this study is that c-Myc decoy ODN-loaded SiO2@PMA-DDA nanocomposites can effectively inhibit cell growth and induce apoptosis in NTERA-2 cancer cells. Moreover, given that a metal core is incorporated into this synthetic nanocomposite, it could potentially be used in conjunction with irradiation as part of a decoy-radiotherapy combinational therapy in future investigations.

Abstract
DNA mimic foldamers based on aromatic oligoamide helices bearing anionic phosphonate side chains have been shown to bind to DNA-binding proteins sometimes orders of magnitude better than DNA itself. Here, we introduce new features in the DNA mimic foldamers to facilitate structural investigations of their interactions with proteins. Thirteen new foldamer sequences have been synthesized and characterized using NMR, circular dichroism, molecular modeling, and X-ray crystallography. The results show that foldamer helix handedness can be quantitatively biased by means of a single stereogenic center, that the foldamer structure can be made C2-symmetrical as in palindromic B-DNA sequences, and that associations between foldamer helices can be promoted utilizing dedicated C-terminal residues that act as sticky ends in B-DNA structures.

Abstract
MicroRNAs (miRNAs/miRs) are small non-coding RNAs that have a multifunction and play essential roles in gene regulation. Their dysregulation is associated with several human cancers. MiR-153 has a critical role in many biological processes, such as suppressing tumor growth (mostly), responses to treatment, and drug resistance. However, miR-153 in some cancers shows a different role as an oncogene, such as prostate. The miR-153 expression can be regulated by several regulators, such as lncRNAs and circular RNAs. By discovering the target factors for miR-153, it may be possible to approach early diagnosis, reversing drug resistance, and treatment of cancers. This will help choose the precise treatment for the patient and not incur additional costs in treatment. Thus, we attempt to summarize the current situation and potential development prospects about the role of miR-153 in cancers. The miR-153 paly an important role in cancers and can be used for diagnosis and prognosis.

Abstract
Scorpion venoms contain potentially useful pharmacological agents. Several studies demonstrate that the venoms of some scorpions induce apoptosis and inhibit the growth of cancer cells; therefore, they have been investigated for isolating anticancer components. In this study, antitumor effects of Hottentotta schach crude venom on MCF-7 (breast cancer cell line) as test group and Vero (African green monkey kidney normal cell line) as control group were analyzed. Cell toxicity was analyzed using MTT and neutral red (NR) uptake assays and apoptosis induction was analyzed using comet assay and caspase-3 activity. Oxidative stress following Hottentotta schach crude venom treatment was analyzed using nitrite oxide (NO) determination assay, reduced glutathione (GSH) and catalase enzyme activity assays. Results showed that crude venom (25-200 μg/mL) induced apoptosis and inhibited the growth of MCF-7 and to a lesser extent in Vero cell lines. Nitrite oxide concentration increased while glutathione concentration and catalase enzyme activity were decreased in MCF-7 cells; however, results in Vero cells were reversed completely. It can be concluded that Hottentotta schach crude venom disturbs the oxidation and reduction potential in cancer cells and ultimately induce apoptosis. So this venom can be used as a good source for isolation and designing new anticancer drugs.

Abstract
Low sensitivity of cancer stem cells toward regular cancer therapy strategies is an important issue in the field of cancer remedy. The concept of cancer stem cell elimination has been a topic of interest in the field of molecular medicine for a long time. At the current study, it was aimed to elevate the sensitivity of cancer stem-like cells toward radiotherapy by treating with Oct4-Sox2 complex decoy oligodeoxynucleotides (ODNs). After treating HT29 and HT29-ShE cells with Oct4-Sox2 complex decoy ODNs, and analyzing the cellular uptake and localization of decoys, treated cells and control groups were subjected to irradiation by fractionated 6MV X-ray with a final dose of 2 Gy. Thereafter, the influence of radiotherapy on ODNs treated groups and control group was investigated on cell viability, cell cycle, apoptosis, colonosphere formation and scratch assay. Cellular uptake and localization assays demonstrated that decoy ODNs can efficiently be transfected to the cells and reside in subcellular compartment, where they pose their action on gene regulation. Post radiotherapy analysis indicated statistical significance in decoy ODNs treated cells by means of lower cell viability, cell cycle arrest in G2/M phase, increased cellular apoptosis, and reduced cell motility. Also, formed colonospheres were smaller in size and fewer in numbers. Considering the role of Oct4, and Sox2 transcription factors in signaling pathways of preserving stemness and inducing reverse EMT, application of decoy strategy could increase the sensitivity of cancer cells toward irradiation, which has a potential to eliminate the cancerous cells from tumors and support cancer treatment.

Abstract
Cancer stem cells are commonly tolerant toward chemotherapy and radiotherapy. Oct4 and Sox2 transcription factors are shown to be overexpressed in various cancers. At the current research, inhibition of Oct4 and Sox2 transcription factors was performed through application of decoy oligodeoxynucleotides (ODNs) strategy via repressing stemness properties in HT29-ShE cells encompassing enriched cancer stem-like cells. Designed Oct4-Sox2 complex decoy ODNs were transfected into HT29-ShE cells with Lipofectamine reagent. At the next step, ODNs efficiency transfection and subcellular localization were determined via flow cytometry and fluorescence microscopy, respectively. Further investigations such as cell proliferation and apoptosis analysis, colonosphere formation, invasion and migration, and real-time PCR assays were also carried out. Obtained results shed light on the fact that the designed complex decoys were effectively transfected into HT29-ShE cells, and they were found to be localized in subcellular compartments. Oct4-Sox2 decoy ODNs led to decreased cell viability, arresting the cell cycle in G0/G1 phases, increasing apoptosis, inhibition of migration/invasion and colonosphere formation ability of HT29-ShE cells in comparison with control and scramble groups. Furthermore, Oct4-Sox2 complex decoy could modulate the MET process via alteration of mRNA expression of downstream genes. It could be concluded that application of Oct4-Sox2 transcription factor decoy strategy in cells with stemness potential could lead to inhibiting the cell growth and triggering differentiation. Therefore, this technique could be applied along with usual remedies (chemotherapy and radiotherapy) as high potential method for treating cancer.

Suppressing the metastatic properties of the breast cancer cells using STAT3 decoy oligodeoxynucleotides: A promising approach for eradication of cancer cells by differentiation therapy. J Cell Physiol 2020; 235:5429-5444. [PMID: 31912904 DOI: 10.1002/jcp.29431] [Citation(s) in RCA: 12] [Impact Index Per Article: 3.0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/07/2019] [Accepted: 12/23/2019] [Indexed: 12/19/2022]
Abstract
Due to the presence of cancer stem cells (CSCs), breast cancer often relapsed after conventional therapies. Strategies that induce differentiation of CSCs will be helpful in eradication of tumor cells, so we designed an oligodeoxynucleotide (ODNs) for targeting of signal transducer and activator of transcription 3 (STAT3) transcription factor which is involved in stemness, and constitutively activated in triple-negative breast cancer. Molecular docking and electrophoretic mobility shift assay analysis showed that decoy ODN bound specifically to the DNA binding site of STAT3 protein. The prevalent uptake of Cy3-labeled ODNs is in the cytoplasm and the nucleus of MDA-MB-231 treated cells. STAT3 decoy ODNs treatment showed cell growth inhibition by decreasing cell viability (17%), increasing the percentage of arrested cells in G0/G1 phases (18%), and triggering apoptosis (29%). Migration and invasion potential decreased from 10.77 to 6.76 µm/hr, by wound closure rate, and migrated/invaded percentage by 26.4% and 15.4% in the transwell assays, respectively. CD44 protein expression level on the cell surface also decreased, while CD24 increased. Mammosphere formation efficiency reduced in terms of tumorsphere size by 47%, while the required time increased. Cells morphology was changed, and lipid droplets were accumulated in the cytoplasm compared to the control and scrambled groups, in all assays (repeated triplicate). Furthermore, the gene expression of all downstream targets significantly decreased owing to suppressing the STAT3 transcription factor. Overall, the results confirmed the antitumor effects of STAT3 decoy in MDA-MB-231 cells. Thus, it seems that STAT3 decoy ODNs might be considered as an auxiliary tool for breast cancer eradicating by the differentiation therapy approach.

Abstract
Cancer ranks as the second leading cause of death worldwide, causing a large social and economic burden. However, most anti-cancer treatments face the problems of tumor recurrence and metastasis. Therefore, finding an effective cure for cancer needs to be solved urgently. Recently, the discovery of cancer stem cells (CSCs) provides a new orientation for cancer research and therapy. CSCs share main characteristics with stem cells and are able to generate an entire tumor. Besides, CSCs usually escape from current anti-cancer therapies, which is partly responsible for tumor recurrence and poor prognosis. microRNAs (miRNAs) belong to small noncoding RNA and regulate gene post-transcriptional expression. The dysregulation of miRNAs leads to plenty of diseases, including cancer. The aberrant miRNA expression in CSCs enhances stemness maintenance. In this review, we summarize the role of miRNAs on CSCs in the eight most common cancers, hoping to bridge the research of miRNAs and CSCs with clinical applications. We found that miRNAs can act as tumor promoter or suppressor. The dysregulation of miRNAs enhances cell stemness and contributes to tumor metastasis and therapeutic resistance via the formation of feedback loops and constitutive activation of carcinogenic signaling pathways. More importantly, some miRNAs may be potential targets for diagnosis, prognosis, and cancer treatments.

Inhibition of transcription factor T-cell factor 3 (TCF3) using the oligodeoxynucleotide strategy increases embryonic stem cell stemness: possible application in regenerative medicine.

Abstract
The transcription factor T-cell factor 3 (TCF3), one component of the Wnt pathway, is known as a cell-intrinsic inhibitor of many pluripotency genes in embryonic stem cells (ESCs) that influences the balance between pluripotency and differentiation. In this study, the effects of inhibition of TCF3 transcription factor on the stemness of mouse ESCs (mESCs) were investigated using the decoy oligodeoxynucleotides (ODNs) strategy. The TCF3 decoy and its scramble ODNs were designed and synthesized. The interaction specificity of the TCF3 decoy with the TCF3 transcription factor was evaluated by the electrophoretic mobility shift assay. Subcellular localization was carried out using fluorescence and confocal microscopy. Self-renewal and pluripotency of mESCs were analyzed by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyl tetrazolium bromide (MTT), cell cycle and apoptosis, alkaline phosphatase (ALP), embryoid body (EB) formation, and real-time assays. All experiments were performed in triplicate. The results showed that knockdown of TCF3 by decoy ODNs transfection in mESCs led to an increase in the cell proliferation, ALP enzyme activity, and master regulatory stemness genes and a decrease in the number and diameter of EBs. These results supported TCF3 as a potential target to maintain the pluripotency and self-renewal capacity of mESCs. Knockdown of the TCF3 transcription factor using decoy ODNs can be a promising method to maintain the stemness of stem cells in regenerative medicine and cell therapy researches.

Abstract
Expression of master transcriptional regulators of stem cells (Oct4 and Sox2) is associated with mediating tumor proliferation and tumor differentiation. The main goal of this study is the investigation of specific binding of designed Oct4-Sox2 transcription factors decoy oligodeoxynucleotides (ODNs) sequence to their nucleus-extracted proteins in HT29-ShE cells containing enriched cancer stem-like cells (SCLCs). First, gene expression of Oct4, Sox2, and E-cadherin revealed the overexpression of Oct4 and Sox2 and downregulation of E-cadherin in HT29-ShE cells compared with HT29 wild-type and HT29-ShC cells. Next, Oct4-Sox2 complex decoy ODNs were designed according to their elements in the promoter region of Sox2 gene. Then, the interactions of Oct4 and Sox2 proteins to designed ODNs were evaluated in silico. Finally, DNA-protein interactions of decoy ODNs and their corresponding proteins were examined by electrophoretic mobility shift assay (EMSA). Analysis of gel shift retardation assay admitted the specific binding of designed ODNs sequence to the nuclear extracted Oct4 and Sox2 proteins. The results will be a promising approach to target cancer stem cells for potential use in differentiation therapy before chemotherapy and radiotherapy of cancers.

Purinergic Signaling Pathway in Human Olfactory Neuronal Precursor Cells. Stem Cells Int 2019; 2019:2728786. [PMID: 31065271 PMCID: PMC6466875 DOI: 10.1155/2019/2728786] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.4] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/07/2018] [Revised: 01/29/2019] [Accepted: 02/07/2019] [Indexed: 12/23/2022] Open
Abstract
Extracellular ATP and trophic factors released by exocytosis modulate in vivo proliferation, migration, and differentiation in multipotent stem cells (MpSC); however, the purinoceptors mediating this signaling remain uncharacterized in stem cells derived from the human olfactory epithelium (hOE). Our aim was to determine the purinergic pathway in isolated human olfactory neuronal precursor cells (hONPC) that exhibit MpSC features. Cloning by limiting dilution from a hOE heterogeneous primary culture was performed to obtain a culture predominantly constituted by hONPC. Effectiveness of cloning to isolate MpSC-like precursors was corroborated through immunodetection of specific protein markers and by functional criteria such as self-renewal, proliferation capability, and excitability of differentiated progeny. P2 receptor expression in hONPC was determined by Western blot, and the role of these purinoceptors in the ATP-induced exocytosis and changes in cytosolic Ca2+ ([Ca2+]i) were evaluated using the fluorescent indicators FM1-43 and Fura-2 AM, respectively. The clonal culture was enriched with SOX2 and OCT3/4 transcription factors; additionally, the proportion of nestin-immunopositive cells, the proliferation capability, and functionality of differentiated progeny remained unaltered through the long-term clonal culture. hONPC expressed P2X receptor subtypes 1, 3-5, and 7, as well as P2Y2, 4, 6, and 11; ATP induced both exocytosis and a transient [Ca2+]i increase predominantly by activation of metabotropic P2Y receptors. Results demonstrated for the first time that ex vivo-expressed functional P2 receptors in MpSC-like hONPC regulate exocytosis and Ca2+ signaling. This purinergic-triggered release of biochemical messengers to the extracellular milieu might be involved in the paracrine signaling among hOE cells.

Abstract
Indirubin, an ingredient in traditional Chinese medicine, is considered as an anti-cancer agent. However, due to its hydrophobic nature, clinical efficiency has been limited. Drug delivery via nanotechnology techniques open new windows toward treatment of cancerous patients. Glioblastoma multiforme (GBM) is the most severe and common type of brain primary tumors. Of common problems in targeting therapies of glioblastoma is the availability of drug in tumoric tissues. In this study, Indirubin loaded solid lipid nanoparticles were prepared and their therapeutic potentials and antitumoric effects were assessed on GBM cell line (U87MG). The SLNs were prepared with Cetyl palmitate and Polysorbat 80 via high-pressure homogenization (HPH) methods in hot mode. Then, properties of SLNs including size, zeta potential, drug encapsulation efficacy (EE %) and drug loading were characterized. SLNs morphology and size were observed using SEM and TEM. The crystalinity of formulation was determined by different scattering calorimetry (DSC). The amount of drug release and antitumor efficiency were evaluated at both normal brain pH of 7.2 and tumoric pH of 6.8. The prapared SLNs had mean size of 130 nm, zeta potential of -16 mV and EE of 99.73%. The results of DSC showed proper encapsulation of drug into SLNs. Drug release assessment in both pH displayed sustain release property. The result of MTT test exhibited a remarkable increment in antitumor activity of Indirubin loaded SLN in comparison with free form of drug and blank SLN on multiform GB. This study indicated that Indirubin loaded SLNs could act as a useful anticancer drugs.
