The role of CD133 (Prominin-1) as a cancer stem cell marker may be useful for therapeutic approaches and prognostication in prostate cancer patients. We investigated the stem-cell-related function and biological features of a subpopulation of CD133+ cells isolated from established primary human prostate cancer cell lines. The CD133+ cells sorted from human prostate cancer 22Rv1 exhibited high clonogenic and tumorigenic capabilities, sphere forming capacity and serially reinitiated transplantable tumors in NOD-SCID mice...

Gene therapy for avoiding intimal hyperplasia of vein grafts after coronary artery bypass grafting is still discussed controversially. A promising application of gene therapy in vein grafts is the use of antisense oligonucleotides to block the expression of genes encoding cell cycle regulatory proteins in vascular smooth muscle cells. C-myc, either directly or by regulating the expression of other proteins, controls cell proliferation, apoptosis and cell survival, tissue remodeling, angiogenesis, cell metabolism, production of inflammatory and anti-inflammatory cytokines, and also participates in cell transformation...

Stem cells derived from human exfoliated deciduous teeth (SHED) represent a promising cell source for bone tissue regeneration. The present study evaluated the effects of interleukin 17A (IL-17A) on the osteogenic differentiation of SHED. SHED were cultured in complete alpha minimum essential medium supplemented with osteoinducing reagents and treated with recombinant IL-17A. The cells were quantitatively analyzed for proliferative activity by MTS assay, cell markers expression as well as apoptotic activity by flow cytometry...

BACKGROUND: SOX2 has gained considerable interest as a pluripotency inducing gene. Co-transfection of SOX2 together with NANOG, KLF4 and c-MYC into adult fibroblasts was able to generate pluripotent stem cells. SOX2 has been reported to be expressed in synovial sarcoma, a tumor being characterized by the SS18-SSX gene fusion forming part of the SWI/SNF chromatin remodeling complex that affects histone methylation. The role of SOX2 in this tumor type as well as other soft tissue tumor entities however is still poorly characterized...

Gastrointestinal Burkitt lymphoma (BL) is a highly aggressive malignancy in childhood, and early treatment is critical for its favorable prognosis. Ultrasonography is a widely accepted initial imaging workup; therefore, recognition of the sonographic features of BL should contribute to its early diagnosis and initiation of treatment. We present a 4-year-old boy with primary jejunal BL with intussusception mimicking presentation, in which initial abdominal US allowed sustainable detection and characterization of the intestinal lesion...

AIM: Develop an objective assay to detect c-MYC protein expression using multiparametric flow cytometry (FCM) as an alternative to immunohistochemistry (IHC). METHODS: 57 patient samples and 11 cell line samples were evaluated. Cell suspensions were obtained and c-MYC staining was performed in combination with CD45 and CD19 and, in some samples, CD10. The percentage of c-MYC+ cells by FCM was correlated with the percentage determined by IHC. The relationship between c-MYC protein expression and the presence of a c-MYC gene rearrangement in aggressive and high-grade lymphomas was also assessed...

Diosmetin, a plant flavonoid, has been shown to exert promising effects on prostate cancer cells as an anti‑proliferative and anticancer agent. In this study, using western blot analysis for protein expression and flow cytometry for cell cycle analysis, we determined that the treatment of the LNCaP and PC‑3 prostate cancer cells with diosmetin resulted in a marked decrease in cyclin D1, Cdk2 and Cdk4 expression levels (these proteins remain active in the G0‑G1 phases of the cell cycle). These changes were accompanied by a decrease in c-Myc and Bcl-2 expression, and by an increase in Bax, p27Kip1 and FOXO3a protein expression, which suggests the potential modulatory effects of diosmetin on protein transcription...

Transcription factor c-Myc is an oncoprotein that is regulated at the post-translational level through phosphorylation of two conserved residues, Serine 62 (Ser62) and Threonine 58 (Thr58). A highly specific tool capable of recognizing Myc via pThr58 is needed to monitor activation and localization. Through phage display, we have isolated 10 engineered Forkhead-associated (FHA) domains that selectively bind to a phosphothreonine (pThr)-containing peptide (53-FELLPpTPPLSPS-64) segment of human c-Myc. One domain variant was observed to bind to the Myc-pThr58 peptide with a KD value of 800 nM and had >1,000-fold discrimination between the phosphorylated and non-phosphorylated peptide...

The structural differences among different G-quadruplexes provide an opportunity for site-specific targeting of a particular G-quadruplex structure. However, majority of G-quadruplex ligands described thus far show little selectivity among different G-quadruplexes. In this work, we delineate the design and synthesis of a crescent-shaped thiazole peptide that preferentially stabilizes c-MYC quadruplex over other promoter G-quadruplexes and inhibits c-MYC oncogene expression. Biophysical analysis such as Förster resonance energy transfer (FRET) melting and fluorescence spectroscopy show that the thiazole peptide TH3 can selectively interact with the c-MYC G-quadruplex over other investigated G-quadruplexes and duplex DNA...

Multiple myeloma (MM) remains an incurable disease in need of the development of novel therapeutic agents and drug combinations. ABT-199 is a specific Bcl-2 inhibitor in clinical trials for MM; however, its activity as a single agent was limited to myeloma patients with the t(11;14) translocation who acquire resistance due to co-expression of Mcl-1 and Bcl-xL. These limitations preclude its use in a broader patient population. We have recently found that a sphingosine kinase 2-specific inhibitor (ABC294640) induces apoptosis in primary human CD138+ cells and MM cell lines...

Transient expression of the transcription factors OCT4, SOX2, KLF4 and C-MYC (OSKM) to induce partial reprogramming while avoiding the pluripotent state and teratoma formation has recently been discussed as a strategy for regenerating damaged tissues in vivo, whereby the impact of partial reprogramming on tissue repair remains to be elucidated. Here, we activated OSKM transcription factors in cutaneous wounds of OSKM-inducible transgenic mice and found that induction of OSKM factors in excisional wounds caused a diminished fibroblast transdifferentiation to myofibroblasts and wound contraction...

Background: Immunotherapy for cervical cancer with type I interferon (IFN) is limited because of the cytotoxicity that accompanies the high doses that are administered. In this study, we investigated the utilization of amniotic fluid-derived mesenchymal stem cells (AF-MSCs) as a means for delivering IFN α to local tumor sites for the suppression of cervical cancer in a mouse model using HeLa cell xenografts. Methods: The tumor tropism ability of AF-MSCs and AF-MSCs genetically modified to overexpress IFN α (IFN α -AF-MSCs) was examined through Transwell in vitro and through fluorescent images and immunohistochemistry in a mouse model...

Although several studies have been conducted to study leptin function, information is very scarce on the molecular mechanism of leptin in fatty acid β-oxidation and oocytes maturation in fish. In this study, we investigated the potential role of fatty acid β-oxidation in leptin-mediated oocytes maturation in Pelteobagrus fulvidraco . Exp. 1 investigated the transcriptomic profiles of ovary and the differential expression of genes involved in β-oxidation and oocytes maturation following rt-hLEP injection; rt-hLEP injection was associated with significant changes in the expression of genes, including twenty-five up-regulated genes ( CPT1 , Acsl , Acadl , Acadm , Hadhb , Echsl , Hsd17b4 , Acca , PPARα , CYP8B1 , ACOX1 , ACBP , MAPK , RINGO , Cdc2 , MEK1 , IGF-1R , APC/C, Cdk2 , GnRHR, STAG3 , SMC1 , FSHβ and C-Myc ) and ten down-regulated gene ( PPARγ , FATCD36 , UBC , PDK1 , Acads , Raf , Fizzy , C3H-4 , Raf and PKC ), involved in fatty acid β-oxidation and oocytes maturation...

The successful application of nucleic acid-based therapy for the treatment of various cancers is largely dependent on a safe and efficient delivery system. A dual-functionalized graphene oxide (GO)-based nanocarrier with the conjugation of aminated-polyethylene glycol (PEG-diamine) and octa-arginine (R8) for the intracellular delivery of nucleic acids is proposed. The functionalized sites are covalently co-conjugated and the PEG : R8 molar ratio is optimized at 10 : 1 to achieve a hydrocolloidally stable size of 252 ± 2...

Proteasome inhibitors have distinct properties and the biochemical consequences of suppressing ubiquitin E1 enzymes and the proteasome differ. We compared the effects of the proteasome inhibitors bortezomib, ixazomib and carfilzomib and the ubiquitin E1 enzyme inhibitor MLN7243/TAK-243 on cell viability and cell death in normal keratinocytes and cutaneous squamous cell carcinoma (cSCC) cell lines. The effects of both a pulse of treatment and more extended incubation were investigated. This is relevant to directly-delivered therapy (topical treatment/intratumoral injection) where the time of exposure can be controlled and a short exposure may better reflect systemically-delivered inhibitor pharmacokinetics...

Targeting of oncogene-driven replicative stress as therapeutic option for high-risk medullobastoma was assessed using a panel of medulloblastoma cells differing in their c-Myc expression [i.e. group SHH (c-Myc low) vs. group 3 (c-Myc high)]. High c-Myc levels were associated with hypersensitivity to pharmacological Chk1 and ATR inhibition but not to CDK inhibition nor to conventional (genotoxic) anticancer therapeutics. The enhanced sensitivity of group 3 medulloblastoma cells to Chk1 inhibitors likely results from enhanced damage to intracellular organelles, elevated replicative stress and DNA damage and activation of apoptosis/necrosis...

Alzheimer's disease (AD) is most the frequent neurodegenerative disease, and the APOE ε4 allele is the most prominent risk factor for late-onset AD. Here, we present an iPSC line generated from peripheral blood cells of a male AD patient employing Sendai virus vectors encoding the transcription factors OCT4, SOX2, KLF4 and c-MYC. The characterized iPSC line expresses typical human pluripotency markers and shows differentiation into all three germ layers, complete reprogramming vector clearance, a normal SNP genotype and maintenance of the APOE ε4/ε4 allele...

Inclusion body hepatitis and hydropericardium-hepatitis syndrome caused by serotype 4 fowl adenovirus (FAdV-4) have emerged in China since 2013. FAdV is usually propagated in primary chicken embryonic liver cells or embryo yolk sac. The aim of this work was to develop an immortalized CEL cell line by stable expression of human mitochondrial ribosomal protein 18S-2, named CEL-hMRP18S-2 cells, for the propagation of FAdV-4. The maximum cell density of CEL-hMRP18S-2 cells could reach 2.65 × 106  cells/ml in four-days culture...
