ABSTRACTBackgroundChromodomain helicase DNA-binding protein 8 (CHD8), which encodes a chromatin remodeling protein that regulates Wnt/β-catenin mediated gene expression, is one of the most strongly associated genes with autism spectrum disorder (ASD). Characterization of ASD patients with CHD8 disrupting mutations and animal and stem cell models of CHD8 deficiency suggest that CHD8 plays a role in neurodevelopment.MethodsWe generated iPSCs from the T-lymphocytes of a healthy, typically-developing human male and iPSC lines from the same source which were subjected to CRISPR/Cas9-mediated knockdown (KD) of CHD8. We subsequently derived neural progenitor cells (NPCs) and neural cells and examined the effects of CHD8 deficiency on cell proliferation and neural differentiation.ResultsWe observed that, compared to WT, CHD8 KD: (1) increased the number of iPSC colonies formed, (2) suppressed spontaneous differentiation along the edges of iPSC colonies, (3) increased the proliferation of NPCs, (4) delayed the formation of neural rosettes, (5) delayed neurite outgrowth, (6) decreased the percentage of cells in the G0/G1 phase of the cell cycle, (7) increased the percentage of cells in the G2/M phase of the cell cycle, (8) decreased presence of the neuronal marker MAP2 although not the glial marker GFAP, (9) decreased presence for the excitatory neuronal marker VGLUT1, and (10) decreased presence of the synaptic marker SYN1.ConclusionsOur results suggest that CHD8 deficiency causes alterations in the cell cycle. More specifically, CHD8 KD appears to increase cell proliferation and delay neural differentiation. This may contribute to the pathophysiology of ASD.

Early Neurogenesis

Histone cell cycle regulator (HIRA) is a histone chaperone and has been identified as an epigenetic regulator. Subsequent studies have provided evidence that HIRA plays key roles in embryonic development, but its function during early neurogenesis remains unknown. Here, we demonstrate that HIRA is enriched in neural progenitor cells, and HIRA knockdown reduces neural progenitor cell proliferation, increases terminal mitosis and cell cycle exit, and ultimately results in premature neuronal differentiation. Additionally, we demonstrate that HIRA enhances β-catenin expression by recruiting H3K4 trimethyltransferase Setd1A, which increases H3K4me3 levels and heightens the promoter activity of β-catenin. Significantly, overexpression of HIRA, HIRA N-terminal domain, or β-catenin can override neurogenesis abnormities caused by HIRA defects. Collectively, these data implicate that HIRA, cooperating with Setd1A, modulates β-catenin expression and then regulates neurogenesis. This finding represents a novel epigenetic mechanism underlying the histone code and has profound and lasting implications for diseases and neurobiology.

Metformin is shown to have hypoglycemic effects. However, the relationship between metformin’s intervention in FFA-induced endoplasmic reticulum stress-mediated insulin resistance (IR) and insulin β-cell apoptosis under high-glucose condition remains unclear. Our study intends to assess their relationship. Human pancreatic β-cells were treated with metformin and cell proliferation and IR were detected by MTT assay along with detection of Wnt/β-catenin signaling by RT-PCR, cell cycle and apoptosis by flow cytometry. Metformin inhibited β cell proliferation which was mediated by FFA-induced endoplasmic reticulum stress in a time-dependent and dose-dependent manner as well as induced cell cycle arrest at G2/M phase. In addition, metformin inhibited β-catenin signaling activation and decreased the expression of c-myc, Dvl-2, survivin, Dvl-3, GSK-3β (p-ser9) and promoted GSK-3 (p-tyr216) and Axin-2 expression. In conclusion, metformin inhibits Wnt/β-catenin signaling and promotes FFA to induce endoplasmic reticulum stress, thereby mediating pancreatic β-cells behaviors.

The Impact

Dysregulation expression of miR-375 is noted to correlate with progression of cervical cancer. This study attempted to investigate the impact of overexpressed miR-375-loaded liposome nanoparticles on proliferation of cervical cancer (CC), to provide an insight on pathogenesis of CC disorder. CC cells were co-cultured with pure liposome nanoparticles (empty vector group), miR-375 agonist-loaded liposome nanoparticles, or transfected with miR-375 antagonist. Besides, some cells were exposed to TGF-β/Smads signaling pathway inhibitor or activator whilst cell proliferation was assessed by MTT assay, and expressions of FZD4 and miR-375 were determined. Western blot analysis was carried out to detect the expression of TGF-β pathway factors (TGF-β, Smad2, Smad7, p-Smad2) and its downstream Smads pathway. The interaction between miR-375 and FZD4 was evaluated by dual-luciferase reporter gene assay. Overexpression of miR-375 induced arrest at the G0/G1 phase of cell cycle and elevation of Smad2 protein expression (P <0.05), with lower expressions of TGF-β, Smad7, p-Smad2, and FZD4, while transfection with miR-375 inhibitor exhibited opposite activity. Presence of miR-375 agonist-loaded liposome nanoparticles induced decreased cell proliferation. There was a targeting relationship between miR-375 and FZD4, and administration with TGF-β/Smads agonist resulted in increased miR-375 and Smad2 expressions, as well as decreased TGF-β, Smad7, p-Smad2, FZD4 protein expression, and the number of S phase and G2/M phase cells (P < 0.05). The signaling inhibitor oppositely suppressed cell proliferation decreasing miR-375 expression. miR-375-loaded liposome nanoparticles activated TGF-β/Smads signaling pathway to restrain cell cycle and suppress cell division, and proliferation through targeting FZD4 in CC. Its molecular mechanism is related to activation of TGF-β/Smads signaling pathway.

Inadequate responses to traditional chemotherapeutic agents in cholangiocarcinoma (CCA) emphasize a requirement for new effective compounds for the treatment of this malignancy. This study aimed to investigate the antiproliferative property of cucurbitacin B on KKU-100 CCA cells. The determination of underlying molecular mechanisms was also carried out. The results revealed that cucurbitacin B suppressed growth and replicative ability to form colonies of CCA cells, suggesting the antiproliferative effect of this compound against the cells. Flow cytometry analysis demonstrated that the interfering effect of cucurbitacin B on the CCA cell cycle at the G2/M phase was accountable for its antiproliferation property. Accompanied with cell cycle disruption, cucurbitacin B altered the expression of proteins involved in the G2/M phase transition including downregulation of cyclin A, cyclin D1, and cdc25A, and upregulation of p21. Additional molecular studies demonstrated that cucurbitacin B suppressed the activation of focal adhesion kinase (FAK) which consequently resulted in inhibition of its kinase-dependent and kinase-independent downstream targets contributing to the regulation of cell proliferation including PI3K/PDK1/AKT and p53 proteins. In this study, the transient knockdown of FAK using siRNA was employed to ascertain the role of FAK in CCA cell proliferation. Finally, the effect of cucurbitacin B on upstream receptor tyrosine kinases regulating FAK activation was elucidated. The results showed that the inhibitory effect of cucurbitacin B on FAK activation in CCA cells is mediated via interference of EGFR and HER2 expression. Collectively, cucurbitacin B might be a promising drug for CCA treatment by targeting FAK protein.

Proliferation And Differentiation

Neural stem cell self-renewal and differentiation is orchestrated by precise control of gene expression involving nuclear receptor TLX. Let-7b, a member of the let-7 microRNA family, is expressed in mammalian brains and exhibits increased expression during neural differentiation. However, the role of let-7b in neural stem cell proliferation and differentiation remains unknown. Here we show that let-7b regulates neural stem cell proliferation and differentiation by targeting the stem cell regulator TLX and the cell cycle regulator cyclin D1. Overexpression of let-7b led to reduced neural stem cell proliferation and increased neural differentiation, whereas antisense knockdown of let-7b resulted in enhanced proliferation of neural stem cells. Moreover, in utero electroporation of let-7b to embryonic mouse brains led to reduced cell cycle progression in neural stem cells. Introducing an expression vector of Tlx or cyclin D1 that lacks the let-7b recognition site rescued let-7b-induced proliferation deficiency, suggesting that both TLX and cyclin D1 are important targets for let-7b-mediated regulation of neural stem cell proliferation. Let-7b, by targeting TLX and cyclin D1, establishes an efficient strategy to control neural stem cell proliferation and differentiation.

Myb Protein

Abstract Myb family transcription factors are found throughout the phyla, and recent studies have demonstrated that Drosophila myb, as well as plant and yeast c-myb-like transcription factors, play an important role in regulating transition though the G1/S and G2/M phases of the cell cycle. Myb’s ability to regulate passage through G2/M is due at least in part to its ability to induce Cyclin B1 expression. A recent study in human T98G ganglioblastoma cells revealed that E2F, together with B-Myb, regulated cyclin B1 expression. Though c-myb was expressed in these cells, it was not found in immunoprecipitated E2F-B-Myb protein complexes and for this reason was felt not to participate in cyclin B1 expression in these cells. Since c-myb plays such a critical role in regulating hematopoietic cell proliferation, and its role in regulating G2/M in blood cells has not previously been explored, we investigated whether c-myb was important is regulating this phase of the cell cycle using K562 and Mo7e cells, as well as PHA stimulated human T lymphocytes. In distinct contrast to findings reported for T98G cells, we now report that in normal and malignant human hematopoietic cells, c-Myb directly upregulates cyclin B1 expression. Several lines of evidence support this claim. First, cyclin B1 expression decreased in Mo7e human leukemia cells in which c-myb had been silenced with siRNA. siRNA targeted to B-myb also decreased cyclin B1 expression, while neither siRNA species decreased cdc2 or cyclin A in these cells. As expected, siRNA targeted against c-myb or B-myb impaired Mo7e cell proliferation. Simultaneous exposure to both siRNA blocked proliferation completely. Second, using an alternative strategy, an inducible dominant negative c-Myb protein also decreased cyclin B1 expression in K562 human leukemia cells. The expected consequence of this, accelerated exit from the M phase, was also observed. Third, we examined c-Myb expression in human T cells by western and Real Time PCR, pre and post PHA stimulation. c-Myb expression began to gradually increase in the G1 phase of cell cycle, continued to increase after S phase, with the maximal protein level being found in G2/M phase, and concordant with cyclin B1 expression. These results indicated a correlation between c-Myb and cyclin B1 expression but did not indicate if c-Myb regulated cyclin B1 expression directly. To address this question, several additional experiments were carried out. A CAT assay showed that overexpressing c-Myb protein could increase activity when driven by a cyclin B1 promoter construct ~5X compared to K562 control cells. Next, examination of the cyclin B1 promoter showed eight potential c-Myb binding sites. Two were canonical [5′-pyrimidine AACG/TG-3′] and located upstream of 6 others which were [5′-AACNG-3′] in type. An in vitro c-Myb binding assay revealed that c-Myb bound the canonical sites. We then performed a Chromatin Immunoprecipitation (ChIP) Assay with anti-c-Myb antibody and specifically enriched cyclin B1 promoter DNA sequences which strongly suggested that c-Myb bound the cyclin B1 promoter in vivo. A control antibody was inactive. Finally, a conditionally active c-Myb restored cyclin B1 mRNA expression in K562 human leukemia cells in presence of cycloheximide within 6 hours. Therefore, in addition to its role in regulating G1/S cell cycle transition, c-Myb also regulates cyclin B1 expression and therefore transition through the G2/M phase in human hematopoietic cells.

Abstract Abstract 1908 Introduction: MAGE-C1/CT7 encodes for a cancer/testis antigen (CTA) frequently expressed in multiple myeloma (MM) that may be a potential target for immunotherapy in this still incurable disease. The expression of this CTA is restricted to malignant plasma cells and a positive correlation between MAGEC1/CT7 expression and advanced stage has been demonstrated for MM. It has been suggested that MAGE-C1/CT7 might play a pathogenic role in MM; however, the exact function of this protein in the pathophysiology of MM is not yet understood. Objectives: (1) To clarify the role of MAGE-C1/CT7 in the control of cellular proliferation and cell cycle regulation in myeloma cell line SKO-007 and (2) to evaluate the impact of silencing MAGE-C1/CT7 on cells treated with bortezomib. Material and Methods: Short hairpin RNA (shRNA) specific for MAGE-C1/CT7 was inserted in the pRETROSUPER(pRS) retroviral vector. The pRS-shRNA-MAGE-C1/CT7 was co-transfected with pCL-amphotropic packing vector in 293T cells to produce virus particles. Sko-007 myeloma cell line was transduced for stable expression of shRNA-MAGE-C1/CT7. Downregulation of MAGE-C1/CT7 was confirmed by real time PCR (RQ-PCR) and western blot. Functional studies included cell proliferation, cell cycle analysis using propidium iodide, and analysis of apoptosis using annexin V staining. Results: SKO-007 MM cell line was transduced for stable expression of shRNA-MAGE-C1/CT7. SKO-007 cells were divided into three derivatives: empty vector (pRS) and ineffective shRNA (antisense strand deleted – GC bases) [both used as controls for all the experiments] and inhibited (shMAGE-C1/CT7). MAGE-C1/CT7 mRNA expression was ∼5 times lower in inhibited cell line than control cells by RQ-PCR. Western blot showed 70–80% decrease in MAGE-C1/CT7 protein expression in inhibited cells when compared with controls. Functional assays did not indicate a difference in cell proliferation and DNA synthesis when inhibited cells were compared with controls. We used empty vector, ineffective shRNA and inhibited cells to determine whether inhibition of MAGE-C1/CT7 was associated with cell cycle dysregulation. We detected differences between inhibited cells and both controls regarding the proportion of myeloma cells in the G2/M phase (p<0.05). When inhibited cells and controls were treated with 10 nM bortezomib for 48h, inhibited cells showed a 48% reduction of cells in the G2/M phase but control cells have 11% (empty vector) and 10% (ineffective shRNA) of reduction (p<0.05). Inhibited cells treated with 15 nM bortezomib showed an increased percentage of apoptotic cells in comparison with bortezomib treated controls (p<0.01) [Figure]. Conclusions: MAGE-C1/CT7 antigen inhibition did not change cell proliferation and DNA synthesis in SKO-007 cells. However, we found that MAGE-C1/CT7 plays in cell cycle regulation, protecting SKO-007 cells against bortezomib-induced apoptosis. Therefore, MAGE-C1/CT7 silencing by shRNA could be a strategy for future therapies in MM, i.e. in combination with proteasome inhibitors.

Background and Objective. It is important to guarantee the quality of stem cells. Serial passage is the main approach to expand stem cells. This study evaluated effects of serial passage on the biological characteristics of human umbilical cord Wharton’s jelly-derived MSCs (WJ MSCs).Methods. Biological properties of WJ MSCs in the early (less than 10 passages, P10), middle (P11–20), and late (more than P20) phases including cell proliferation, cell cycle, phenotype, senescence, oncogene expression, stemness marker expression, and differentiation capacity were evaluated using flow cytometry, real-time PCR, immunocytofluorescence, and western blot.Results. It was found that there were no significant differences in cell proliferation, cell cycle, phenotype, and stemness marker expression in different phases. However, the expression of senescence-related gene, p21, and oncogene, c-Myc, was significantly upregulated in the late phase, which had close relations with the obviously increased cell senescence. Moreover, cardiac differentiation capability of WJ MSCs decreased whereas the propensity for neural differentiation increased significantly in the middle phase.Conclusions. This study reveals that WJ MSCs in the early and middle phases are relatively stable, and effect of serial passage on the lineage-specific differentiation should be considered carefully.

Background. This study is to explore the effect of corilagin on the proliferation and NF-κB signaling pathway in U251 glioblastoma cells and U251 glioblastoma stem-like cells.Methods. CD133 positive U251 glioblastoma cells were separated by immunomagnetic beads to isolate glioblastoma stem-like cells. U251 cells and stem-like cells were intervened by different corilagin concentrations (0, 25, 50, and 100 μg/mL) for 48 h, respectively. Cell morphology, cell counting kit-8 assay, flow cytometry, dual luciferase reporter assay, and a western blot were used to detect and analyze the cell proliferation and cell cycle and investigate the expression of IKBαprotein in cytoplasm and NF-κB/p65 in nucleus.Results. Corilagin inhibited the cell proliferation of U251 cells and their stem-like cells and the inhibition role was stronger in U251 stem-like cells (P<0.05). The cell cycle was arrested at G2/M phase in the U251 cells following corilagin intervention; the proportion of cells in G2/M phase increased as the concentration of corilagin increased (P<0.05). The U251 stem-like cells were arrested at the S phase following treatment with corilagin; the proportion of cells in the S phase increased as the concentration of corilagin increased (P<0.05). The ratio of dual luciferase activities of U251 stem-like cells was lower than that of U251 cells in the same corilagin concentration. With increasing concentrations of corilagin, the IKBαexpression in cytoplasm of U251 cells and U251 stem-like cells was increased, but the p65 expression in nucleus of U251 cells and U251 stem-like cells was decreased (P<0.05).Conclusion. Corilagin can inhibit the proliferation of glioblastoma cells and glioblastoma stem-like cells; the inhibition on glioblastoma stem-like cell proliferation is stronger than glioblastoma cells. This different result indicates that the effect of corilagin on U251 cells and U251 stem-like cells may have close relationships with mechanism of cell cycle and NF-κB signaling pathway; however, the real antitumor mechanism of corilagin is not yet clear and requires further study.
