Cytokines regulate numerous cell processes, including connexin expression and gap junctional coupling. In this study, we examined the effect of ciliary neurotrophic factor (CNTF) on connexin43 (Cx43) expression and intercellular coupling in astrocytes. Murine cortical astrocytes matured in vitro were treated with CNTF (20 ng/ml), soluble ciliary neurotrophic factor receptor α (CNTFRα) (200 ng/ml), or CNTF-CNTFRα. Although CNTF and CNTFRα alone had no effect on Cx43 expression, the heterodimer CNTF-CNTFRα significantly increased both Cx43 mRNA and protein levels. Cx43 immunostaining correlated with increased intercellular coupling as determined by dye transfer analysis. By using the pharmacological inhibitor α-cyano-(3,4-dihydroxy)-N-benzylcinnamide (AG490), the increase in Cx43 was found to be dependent on the Janus tyrosine kinase/signal transducer and activator of transcription (JAK/STAT) pathway. Immunocytochemical analysis revealed that CNTF-CNTFRα treatment produced nuclear localization of phosphorylated STAT3, whereas CNTF treatment alone did not. Transient transfection of constructs containing various sequences of the Cx43 promoter tagged to a LacZ reporter into ROS 17/2.8 cells confirmed that the promoter region between -838 to -1693 was deemed necessary for CNTF-CNTFRα to induce heightened expression. CNTF-CNTFRα did not alter Cx30 mRNA levels, suggesting selectivity of CNTF-CNTFRα for connexin signaling. Together in the presence of soluble receptor, CNTF activates the JAK/STAT pathway leading to enhanced Cx43 expression and intercellular coupling.

Background: Prostate cancer (PCa) remains the most common diagnosed tumor and is the second-leading cause of cancer-related death in men. If the cancer is organ-confined it can be treated by various ablative therapies such as RP (radical prostatectomy), RT (radiation therapy), brachytherapy, cryosurgery or HIFU (High-Intensity Focused Ultrasound). However, advanced or metastatic PCa treatment requires systemic therapy involving androgen deprivation, but such patients typically progress to refractory disease designated as castration-resistant prostate cancer (CRPC). Interleukin-6 (IL-6) has been established as a driver of prostate carcinogenesis and tumor progression while less is known about the role of ciliary neurotrophic factor (CNTF), a member of the IL-6 cytokine family in prostate cancer. Moreover, MAPK/ERK, AKT/PI3K and Jak/STAT pathways that regulate proliferative, invasive and glucose-uptake processes in cancer progression are triggered by CNTF. Methods: We investigate CNTF and its receptor CNTFRα expressions in human androgen-responsive and castration-resistant prostate cancer (CRPC) by immunohistochemistry. Moreover, we investigated the role of CNTF in proliferative, invasive processes as well as glucose uptake using two cell models mimicking the PCa (LNCaP cell line) and CRPC (22Rv1 cell line). Conclusions: Our results showed that CNTF and CNTFRa were expressed in PCa and CRPC tissues and that CNTF has a pivotal role in prostate cancer environment remodeling and as a negative modulator of invasion processes of CRPC cell models.

Small-cell lung cancer (SCLC) is the most aggressive lung cancer type, and is associated with smoking, low survival rate due to high vascularization, metastasis and drug resistance. Alterations in MYC family members are biomarkers of poor prognosis for a large number of SCLC. In particular, MYCN alterations define SCLC cases with immunotherapy failure. MYCN has a highly restricted pattern of expression in normal cells and is an ideal target for cancer therapy but is undruggable by traditional approaches. We propose an innovative approach to MYCN inhibition by an MYCN-specific antigene—PNA oligonucleotide (BGA002)—as a new precision medicine for MYCN-related SCLC. We found that BGA002 profoundly and specifically inhibited MYCN expression in SCLC cells, leading to cell-growth inhibition and apoptosis, while also overcoming multidrug resistance. These effects are driven by mTOR pathway block in concomitance with autophagy reactivation, thus avoiding the side effects of targeting mTOR in healthy cells. Moreover, we identified an MYCN-related SCLC gene signature comprehending CNTFR, DLX5 and TNFAIP3, that was reverted by BGA002. Finally, systemic treatment with BGA002 significantly increased survival in MYCN-amplified SCLC mouse models, including in a multidrug-resistant model in which tumor vascularization was also eliminated. These findings warrant the clinical testing of BGA002 in MYCN-related SCLC.

Abstract Neuronal and axonal degeneration results in irreversible neurological disability in multiple sclerosis (MS) patients. A number of adaptive or neuroprotective mechanisms are thought to repress neurodegeneration and neurological disability in MS patients. To investigate possible neuroprotective pathways in the cerebral cortex of MS patients, we compared gene transcripts in cortices of six control and six MS patients. Out of 67 transcripts increased in MS cortex nine were related to the signalling mediated by the neurotrophin ciliary neurotrophic factor (CNTF). Therefore, we quantified and localized transcriptional (RT-PCR, in situ hybridization) and translational (western, immunohistochemistry) products of CNTF-related genes. CNTF-receptor complex members, CNTFRα, LIFRβ and GP130, were increased in MS cortical neurons. CNTF was increased and also expressed by neurons. Phosphorylated STAT3 and the anti-apoptotic molecule, Bcl2, known down stream products of CNTF signalling were also increased in MS cortical neurons. We hypothesize that in response to the chronic insults or stress of the pathogenesis of multiple sclerosis, cortical neurons up regulate a CNTF-mediated neuroprotective signalling pathway. Induction of CNTF signalling and the anti-apoptotic molecule, Bcl2, thus represents a compensatory response to disease pathogenesis and a potential therapeutic target in MS patients.

Background. Early cervical lymph node (LN) metastasis is an important cause of poor survival in patients with medullary thyroid cancer (MTC). This study evaluated whether the preoperative serum calcitonin level in combination with ultrasonographic features of MTC can be used to assess the LN status as well as predict the risk of metastasis in patients with MTC. Methods. We retrospectively analyzed the clinical data of 95 patients with MTC, and a nomogram model was constructed and validated. Using integrated database analysis of The Cancer Genome Atlas (TCGA) and Genotype-Tissue Expression (GTEx), we mined pathways wherein CALCA is involved, identified calcitonin-related genes, and analyzed their functions. Results. Correlation analysis revealed a significant association between the infiltrating range, diameter, calcification, blood flow, the preoperative serum calcitonin level, and metastasis. The metastasis risk-prediction model showed great accuracy in determining the risk of metastasis in MTC (area under the curve of the receiver operating characteristic [ROC] curve: 0.979 [95% confidence interval 0.946–1.000]). Decision curve analysis (DCA) showed that the model has excellent clinical utilization potential. Significantly, CALCA, the mRNA for calcitonin, was highly expressed in thyroid cancer tissues and associated with the cytokine–cytokine receptor and neuroactive ligand-receptor interaction pathways as well as the cell-adhesion molecules. ROC curve indicated that the CNTFR, CD27, GDF6, and TSLP genes, which are related to the cytokine–cytokine receptor interaction pathway, could indicate the risk of metastasis in MTC. Conclusions. The preoperative serum calcitonin level, in combination with ultrasonographic features, can be used to predict the risk of metastasis in patients with MTC and constitute a noninvasive accurate method for preoperative diagnosis of MTC.

Abstract Cardiotrophin-like cytokine factor 1 (CLCF1) is a neurotrophic factor initially identified as a B lymphocyte stimulating factor. Mutations in CLCF1 cause type 2 Cold-Induced Sweating Syndrome, a severe multisystem disorder coupled with recurrent childhood infections. The CLCF1-CRLF1 composite cytokine mediate its neurotrophic effects via the CNTF receptor (CNTFR). Although immune cells do not express CNTFR, immunological activities of CLCF1 have been described, suggesting the existence of an alternative receptor. Preliminary results suggest that CLCF1 can associate with the Epstein-Barr virus-induced gene 3(EBI3). EBI3 is a subunit of the composite cytokines IL-27, IL-35 and IL-39, which exhibits immunoregulatory functions. Our hypothesis is that CLCF1 associates with EBI3 to activate an alternative receptor expressed by immune cells. The aim of the project is to identify the cells producing CLCF1/EBI3, to define its receptor and to characterize the influence of CLCF1/EBI3 on lymphocyte proliferation, differentiation, and function. We find that EBI3 and CLCF1 subunits can associate extracellularly to form a CLCF1/EBI3 complex. Moreover, we uncovered that this complex can bind to IL-12Rß1, IL-23R and CNTFRα receptor chains. Altogether, our data strongly suggest that the CLCF1/EBI3 complex is likely to assemble in vivo and act as a cytokine through known receptor chains. Overall, defining the cellular targets and biological activities of CLCF1/EBI3 will pave the way for the development of treatments in autoimmune diseases involving CLCF1 and EBI3, adding to the increasing number of biologic drugs targeting cytokines, their receptors, or signaling pathways that are used clinically to treat inflammatory diseases.

Abstract Breast cancer is the most frequently diagnosed cancer, and second most common source of brain metastasis in women. Despite recent advances in detection and therapeutics, patients with breast cancer brain metastases (BCBM) survive only 6-18 months after diagnosis. HER2-enriched breast cancer and triple-negative breast cancer (TNBC) subtypes have the highest propensity to metastasize to the brain. Mechanisms that drive BCBM remain unclear, contributing to limited effective treatments and poor prognoses for HER2-enriched breast cancer and TNBC patients. Truncated glioma-associated oncogene homolog 1 (tGLI1), a gain-of-function GLI1 transcription factor discovered in our lab, promotes BCBM of circulating tumor cells in vivo. We previously reported that tGLI1 enriches the breast cancer stem cell (BCSC) subpopulation, and that tGLI1-positive BCSCs strongly activate astrocytes, the most abundant glial cell type in the brain. The mechanisms by which tGLI1-activated astrocytes promote BCBM have not been investigated. Since tumor-associated astrocytes have been reported to secrete specific cytokines, such as ciliary neurotrophic factor (CNTF), to activate astrocytes and cancer cells by binding to IL-6R and CNTF receptor-alpha (CNTFRα), we determined whether astrocytes activated by tGLI1-positive breast cancer cells secrete elevated levels of CNTF. Results of CNTF ELISA revealed that conditioned media from tGLI1-positive breast cancer cells increases the ability of astrocytes to secrete CNTF compared to GLI1-positive or control cells. Furthermore, we found that exogenous CNTF significantly activates astrocytes and promotes BCSCs, important mediators of tumor progression and metastasis in breast cancer. Analysis of patient datasets reveals CNTFRα is more highly expressed in brain metastases compared to breast cancer and normal breast tissues, suggesting that CNTF secreted by activated astrocytes can promote the growth of BCSCs in the brain. We further found that CNTF and CNTFRα gene signatures are significantly associated with worse brain metastasis-free survival, suggesting an important role for the tGLI1-CNTF-CNTFRα pathway in BCBM development. In summary, our study demonstrates for the first time that astrocytes activated by tGLI1-expressing BCBM secrete CNTF, CNTF further activates astrocytes and promotes BCSCs, and that this tumor-astrocyte interaction could be a novel mechanism for BCBM development and progression.

Abstract Objective. Thyroid hormones play an important role in the development and maturation of the central nervous symptom and their failure in the prenatal period leading to an irreversible brain damage. Their effect on the brain of adult, however, has not been fully studied. With the discovery of neurogenesis in the adult brain, many recent studies have been focused on the understanding the basic mechanisms controlling this process. Many neurogenesis regulatory genes are not only transcribed but also translated into the blood cells. The goal of our study was to analyze the transcriptional activity of neurogenesis regulatory genes in peripheral blood cells in patients with thyroid pathology. Methods. The pathway-specific PCR array (Neurotrophins and Receptors RT2 Profiler PCR Array, QIAGEN, Germany) was used to identify and validate the neurogenesis regulatory genes expression in patients with thyroid pathology and control group. Results. The results showed that GFRA3, NGFR, NRG1, NTF3, NTRK1, and NTRK2 significantly decreased their expression in patients with autoimmune thyroiditis with rising serum of autoantibodies. The patients with primary hypothyroidism, as a result of autoimmune thyroiditis and postoperative hypothyroidism, had significantly lower expression of FGF2, NGFR, NRG1, and NTF3. The mRNA level of CNTFR was markedly decreased in the group of patients with postoperative hypothyroidism. No change in the ARTN, PSPN, TFG, MT3, and NELL1 expression was observed in any group of patients. Conclusion. The finding indicates that a decrease in thyroid hormones and a high level of autoantibodies, such as anti-thyroglobulin antibody and anti-thyroid peroxidase antibody, affect the expression of mRNA neurogenesis-regulated genes in patients with thyroid pathology.

Object Tumor-initiating cells are uniquely resilient to current treatment modalities and play an important role in tumor resistance and recurrence. The lack of specific tumor-initiating cell markers to identify and target these cells presents a major obstacle to effective directed therapy. Methods To identify tumor-initiating cell markers in primary brain tumors, the authors compared the proteomes of glioma tumor-initiating cells to their differentiated progeny using a novel, nongel/shotgun-based, multidimensional liquid-chromatography protein separation technique. An in vivo xenograft model was used to demonstrate the tumorigenic and stem cell properties of these cells. Western blot and immunofluorescence analyses were used to confirm findings of upregulated ciliary neurotrophic factor receptor subunit–α (CNTFRα) in undifferentiated tumor-initiating cells and gliomas of increasing tumor grade. Sequencing of the CNTFRα coding regions was performed for mutation analysis. Finally, antibody-dependent cell-mediated cytotoxicity was used to establish the role of CNTFRα as a potential immunotherapeutic target. Results Ciliary neurotrophic factor receptor subunit–α expression was increased in tumor-initiating cells and was decreased in the cells' differentiated progeny, and expression levels increased with glioma grade. Mutations of CNTFRα are not common in gliomas. Functional studies using CNTF treatment in glioma tumor-initiating cells showed induction of differentiation through the CNTFRα pathway. Treatment with anti-CNTFRα antibody resulted in increased antibody-dependent cell-mediated cytotoxicity in CNTFRα expressing DAOY cells but not in cell lines that lack CNTFRα. Conclusions These data indicate that CNTFRα plays a role in the formation or maintenance of tumor-initiating cells in gliomas, is a marker that correlates with histological grade, may underlie treatment resistance in some cases, and is a potential therapeutic target.

Full textAbstract:
Growing evidences suggest that obesity is associated with hypothalamic leptin resistance, leading to the alteration of food intake control. Alternative treatment using ciliary neurotrophic factor (CNTF) has been suggested because CNTF exerts a leptin-like effect, even in leptin-resistant states, but the mechanisms by which CNTF maintains this effect are not yet understood. Both leptin and CNTF act in the hypothalamus through similar signaling pathways including janus kinase-2/signal transducer and activator of transcription (STAT)-3 pathway. To explore the differences and interactions between leptin and CNTF signaling pathways, differentiated human neuroblastoma cells (SH-SY5Y) were exposed to either leptin or CNTF and then challenged for each cytokine. Leptin pretreatment completely abolished leptin-dependent STAT-3 and ERK 1/2 phosphorylations without affecting CNTF action. The lack of cross-desensitization between leptin and CNTF signaling pathways occurred despite the induction of suppressor of cytokine signaling-3 in response to both cytokines. Interestingly, leptin as well as insulin induced the expression of phosphotyrosine phosphatase (PTP)-1B, whereas CNTF treatment did not affect its expression. In addition, acute leptin treatment but not CNTF induced PTP-1B expression in mouse hypothalamic arcuate nucleus. Furthermore, the overexpression of human PTP-1B in SH-SY5Y cells completely abolished leptin- and insulin-dependent janus kinase-2, STAT-3, and ERK 1/2 phosphorylations, but CNTF action was not altered. Collectively, our results suggest that PTP-1B constitutes a key divergent element between leptin/insulin and CNTF signaling pathways at the neuronal level, which may constitute a possible mechanism that explains the efficacy of CNTF in leptin-resistant states. Phosphotyrosine phosphatase 1B has a critical role in the onset of neuronal leptin resistance and is unable to inhibit CNTF-dependent signaling pathways in leptin-resistant states.

One of the major limitations in drug development and gene therapy for brain diseases is the natural defensive structure called the blood brain barrier (BBB), which prevents therapeutic polypeptide drugs and viral vectors from entering the brain. Intranasal delivery of therapeutic gene products into the brain offers a non-invasive alternative towards a feasible gene and protein therapy for neurological diseases. From recent studies involving axonal transport, it is tempting to speculate that therapeutic macromolecules including neurotrophic factors and viral vectors can be delivered into the brain by peripheral neurons, such as olfactory receptor neurons (ORNs), which span the BBB. It is thought that the nasal pathway into the brain involves two general mechanisms; intracellular (intraneuronal) or extracellular routes of transport. However the pathways involved have not yet been fully characterized.
In this study I firstly investigated the temporal and spatial localisation pattern of both biotinylated and I125 labelled ciliary neurotrophic factor (CNTF) following nasal delivery into Sprague-Dawley rats. Results showed that intranasal delivered CNTF was transported to several brain regions by both intracellular axonal pathway through ORNs and the extracellular trigeminal pathway. Excess unlabelled CNTF competed for receptor binding in the olfactory mucosa confirming receptor mediated intracellular transport to the olfactory bulb via ORNs. Denervation of the olfactory mucosa prior to CNTF delivery failed to prevent CNTF transport to trigeminal and hypothalamic brain regions. Intranasal delivered CNTF was biologically active, resulting in activation of the STAT3 signalling pathway in the thalamus and hypothalamus.
To examine the functional activity of intranasal delivered CNTF, I conducted a weight loss trial using an obese Zucker rat (OZR) model to test whether CNTF treatment caused body weight loss. Intranasal administration of CNTF resulted in reduced body weight in the CNTF treated OZR group compared to the BSA control group during the 12 day trial and for 3 days after. Intranasal delivery of CNTF may be a valuable method for the treatment of obesity.
In the second study, I investigated the temporal and spatial expression of Enhanced Green Fluorescent Protein (EGFP) transferred by a single nasal delivery of either a recombinant adenovirus vector (Ad5CMV-EGFP) or an adeno-associated virus vector (AAV2-EGFP) into Sprague-Dawley rats. Adenovirus mediated EGFP expression was localized in ORNs throughout the olfactory epithelium after 24 hours. EGFP in the ORNs appeared to be anterogradely transported along their axons to the olfactory bulb and transferred in glomeruli to second-order neurons. EGFP was transferred to several brain regions including the cortex, hippocampus, and brainstem after 7 days. EGFP expression co-localized with Olfactory Marker Protein and was confirmed with EGFP immunofluorescence labelling and western blotting. AAV expressed EGFP localized in similar olfactory and brain regions 6 weeks after delivery. mRNA levels suggested that the AAV-EGFP construct was only incorporated into olfactory mucosa cells and the viral vector was not present in olfactory bulb and brain regions.
In conclusion, this simple and non-invasive polypeptide and gene delivery method provides ubiquitous macromolecule distribution throughout the rodent brain and may be useful for the treatment of neurological disorders.
