Abstract
Glioma cells overexpress different peptide receptors that are useful for research, diagnosis, management, and treatment of the disease. Oncogenic peptides favor the proliferation, migration, and invasion of glioma cells, as well as angiogenesis, whereas anticancer peptides exert antiproliferative, antimigration, and anti-angiogenic effects against gliomas. Other peptides exert a dual effect on gliomas, that is, both proliferative and antiproliferative actions. Peptidergic systems are therapeutic targets, as peptide receptor antagonists/peptides or peptide receptor agonists can be administered to treat gliomas. Other anticancer strategies exerting beneficial effects against gliomas are discussed herein, and future research lines to be developed for gliomas are also suggested. Despite the large amount of data supporting the involvement of peptides in glioma progression, no anticancer drugs targeting peptidergic systems are currently available in clinical practice to treat gliomas.

Abstract
BACKGROUND Improved treatment of glioblastoma (GBM) needs to address tumor invasion, a hallmark of the disease that remains poorly understood. In this study, we profiled GBM invasion through integrative analysis of histological and single-cell RNA sequencing (scRNA-seq) data from 10 patients. METHODS Human histology samples, patient-derived xenograft mouse histology samples, and scRNA-seq data were collected from 10 GBM patients. Tumor invasion was characterized and quantified at the phenotypic level using hematoxylin and eosin and Ki-67 histology stains. Crystallin alpha B (CRYAB) and CD44 were identified as regulators of tumor invasion from scRNA-seq transcriptomic data and validated in vitro, in vivo, and in a mouse GBM resection model. RESULTS At the cellular level, we found that invasive GBM are less dense and proliferative than their non-invasive counterparts. At the molecular level, we identified unique transcriptomic features that significantly contribute to GBM invasion. Specifically, we found that CRYAB significantly contributes to postoperative recurrence and is highly co-expressed with CD44 in invasive GBM samples. CONCLUSIONS Collectively, our analysis identifies differentially expressed features between invasive and nodular GBM, and describes a novel relationship between CRYAB and CD44 that contributes to tumor invasiveness, establishing a cellular and molecular landscape of GBM invasion.

Abstract
Glioblastoma (GBM) is one of the most common malignant and incurable brain tumors. The identification of a gene signature for GBM may be helpful for its diagnosis, treatment, prediction of prognosis and even the development of treatments. In this study, we used the GSE108474 database to perform GSEA and machine learning analysis, and identified a 33-gene signature of GBM by examining astrocytoma or non-GBM glioma differential gene expression. The 33 identified signature genes included the overexpressed genes COL6A2, ABCC3, COL8A1, FAM20A, ADM, CTHRC1, PDPN, IBSP, MIR210HG, GPX8, MYL9 and PDLIM4, as well as the underexpressed genes CHST9, CSDC2, ENHO, FERMT1, IGFN1, LINC00836, MGAT4C, SHANK2 and VIPR2. Protein functional analysis by CELLO2GO implied that these signature genes might be involved in regulating various aspects of biological function, including anatomical structure development, cell proliferation and adhesion, signaling transduction and many of the genes were annotated in response to stress. Of these 33 signature genes, 23 have previously been reported to be functionally correlated with GBM; the roles of the remaining 10 genes in glioma development remain unknown. Our results were the first to reveal that GBM exhibited the overexpressed GPX8 gene and underexpressed signature genes including CHST9, CSDC2, ENHO, FERMT1, IGFN1, LINC00836, MGAT4C and SHANK2, which might play crucial roles in the tumorigenesis of different gliomas.

Abstract
Aim: Ovarian cancer (OC) is a gynecological malignancy with a challenging judgment of prognosis due to complicated etiology and high recurrence rate. The oncostatin M receptor (OSMR) from members of the IL-6 receptor family is associated with tumor development. This study aims to explore the correlations between OSMR gene polymorphisms (rs2278329 [G/A, missense, Asp553Asn], rs2292016 [G/T, promoter, -100G/T]) and OC. Methods: This study enrolled 160 OC patients and 397 healthy controls. Genotypes of two single-nucleotide polymorphisms were distinguished using TaqMan SNP Genotyping Assay, and statistical analysis was performed using SPSS software. Results: A significantly decreased overall survival rate was found in serous OC patients carrying rs2278329 GA/AA genotypes. Meanwhile, TT genotype carriers of rs2292016 had an improved relapse rate, and the GT genotype showed a definitive correlation with a lower relapse rate. Conclusion: OSMR gene polymorphisms may be related to recurrence and overall survival of serous OC patients.

Glycolytic activation of monocytes regulates the accumulation and function of neutrophils in human hepatocellular carcinoma. J Hepatol 2020; 73:906-917.

Abstract
BACKGROUND & AIMS Neutrophils are one of the most abundant components in human hepatocellular carcinoma (HCC) and have been shown to play important roles in regulating disease progression. However, neutrophils are very short-lived cells in circulation, and mechanisms regulating their accumulation and functions in HCC are not yet fully understood. METHODS Monocytes were purified from non-tumor or paired tumor tissues of patients with HCC, and their production of neutrophil-attracting chemokines was evaluated. Mechanisms regulating the expression of CXCL2/8 by tumor monocytes, and the role of tumor monocyte-derived chemokines and cytokines in modulating neutrophil accumulation and functions were studied with both ex vivo analyses and in vitro experiments. RESULTS Monocyte-derived CXCL2 and CXCL8 were major factors in regulating the recruitment of neutrophils into tumor milieus. These chemokines, in addition to tumor-derived soluble factors, could inhibit apoptosis and sustain survival of neutrophils, thus leading to neutrophil accumulation in tumor tissues. Moreover, monocyte-derived TNF-α acted synergistically with tumor-derived soluble factors to induce the production of the pro-metastasis factor OSM by neutrophils. Further, the glycolytic switch in tumor-infiltrating monocytes mediated their production of CXCL2 and CXCL8 via the PFKFB3-NF-κB signaling pathway. Accordingly, levels of PFKFB3, CXCL2/CXCL8 production in monocytes and infiltration of OSM-producing neutrophils were positively correlated in human HCC tissues. CONCLUSIONS Our results unveiled a previously unappreciated link between monocytes and neutrophils in human HCC, identifying possible targets that could be therapeutically exploited in the future. LAY SUMMARY Neutrophils constitute a major but poorly understood component of human hepatocellular carcinoma (HCC). Herein, we unveil a novel mechanism by which metabolic switching in monocytes promotes the accumulation of neutrophils in the tumors of patients with HCC. Both monocyte-produced chemokines and signals from the tumor microenvironment promote the production of the pro-metastatic factor OSM by neutrophils. These data identify potential targets for immune-based anticancer therapies for HCC.

Abstract
BACKGROUND Oncostatin M receptor (OSMR) is a member of the interleukin 6 (IL-6) receptor family that transduces signaling events of Oncostatin M (OSM). OSM-OSMR signaling plays a key role in inflammation and cancer progression. However, the role of OSM-OSMR in gastric cancer (GC) is still unknown. METHODS OSMR expression in GC was determined by real-time PCR (RT-PCR), immunohistochemistry (IHC) and Western blot. The effects of OSM-OSMR on GC cell proliferation, migration, invasion, and epithelial-mesenchymal transition (EMT) in vitro and metastasis in vivo were examined. The pathways underlying OSM-OSMR signaling were explored by Western blot. Regulatory mechanism between SP1 and OSMR was explored in vitro. RESULTS OSMR was highly expressed in GC tissues and its expression level was closely associated with age, T stage, Lauren classification, lymph node metastasis, TNM stage and worse prognosis of patients with GC. Knockdown of OSMR expression in GC cells significantly inhibited cell proliferation, migration, invasion, and EMT in vitro, as well as tumorigenesis and peritoneal metastasis in vivo induced by OSM. These effects mediated by OSM-OSMR were dependent on the activation of STAT3/FAK/Src signaling. SP1 could bind to the promoter region of human OSMR gene from - 255 to - 246 bp, and transcriptionally regulated OSMR overexpression in GC cells. CONCLUSIONS OSM-OSMR contributes to GC progression through activating STAT3/FAK/Src signaling, and OSMR is transcriptionally activated by SP1.

Abstract
The importance of microenvironment on dendritic cell (DC) function and development has been strongly established during the last two decades. Although DCs with general tolerogenic characteristics have been isolated and defined as a particular sub-population, it is predominantly their unequivocal biological plasticity, which allows for unparalleled responsiveness to environmental ques and shaping of their tolerogenic characteristics when interacting with tolerance-inducing biomolecules. Dendritic cells carry receptors for a great number of endogenous factors, which, after ligation, can importantly influence the development of their activation state. For this there is ample evidence merely by observation of DC characteristics isolated from various anatomical niches, e.g., the greater immunosuppressive potential of DCs isolated from intestine compared to conventional blood DCs. Endogenous biomolecules present in these environments most likely play a major role as a determinant of their phenotype and function. In this review, we will concisely summarize in what way various, tolerance-inducing endogenous factors influence DC biology, the development of their particular tolerogenic state and their subsequent actions in context of immune response inhibition and induction of regulatory T cells.

Subcutaneously administered adrenomedullin exerts a potent therapeutic effect in a murine model of ulcerative colitis. Hum Cell 2018; 32:12-21.

Abstract
Adrenomedullin (AM) exerts a potent anti-inflammatory effect. Intrarectal or consecutive intravenous administrations of AM reduce pathological manifestations in rodent colitis models. However, in clinical applications, a safer administration route that provides stronger alleviation of patient burden is preferred. We investigated whether subcutaneously administered AM is effective against dextran sulfate sodium (DSS)-induced colitis. C57BL/6J mice were administered 1% DSS in drinking water and received AM at 8, 40 or 80 nmol/kg subcutaneously once a day for 7 consecutive days. Subcutaneously administered AM significantly and dose-dependently ameliorated body weight loss, diarrhea, and histological severity of colonic inflammation in DSS-treated mice. The AM therapeutic effect was associated with the upregulation of the production of autocrine AM, and expression of cAMP, c-fos, KLF4, and downregulation of STAT3 and NF-κB p65 phosphorylation, as well as a decrease in proinflammatory cytokine expression in the colon. Subcutaneous AM treatment potently attenuated DSS-induced colitis, which suggests that AM administered subcutaneously in ulcerative colitis (UC) patients may decrease diseases burden and improve quality of life.

Abstract
The finding that hypoxia can induce cancer stemness in various experimental models is in agreement with the conceptual basis of cancer cell plasticity. Here, we aimed to gain insights into the molecular basis of hypoxia-induced cancer cell plasticity in triple negative breast cancer (TNBC). To achieve this goal, we employed our previously published in-vitro model of TNBC, in which a small subset of stem-like cells can be distinguished from the bulk cell population based on their responsiveness to a Sox2 reporter. In MDA-MB-231, a TNBC cell line, we observed that hypoxia significantly increased the expression of luciferase and green fluorescence protein (GFP), the readouts of the Sox2 reporter. Upon hypoxic challenge, the bulk, reporter unresponsive (RU) cells acquired stem-like features, as evidenced by the significant increases in the proportion of CD44high/CD24low cells, colony formation and resistance to cisplatin. Correlating with these phenotypic changes, RU cells exposed to hypoxia exhibited a substantial upregulation of the active/phosphorylated form of STAT3 (pSTAT3). This hypoxia-induced activation of STAT3 correlated with increased STAT3 transcriptional activity, as evidenced by increased STAT3-DNA binding and an altered gene expression profile. This hypoxia-induced STAT3 activation is biologically significant, since siRNA knockdown of STAT3 in RU cells significantly attenuated the hypoxia-induced acquisition of Sox2 activity and stem-like phenotypic features. In conclusion, our data have provided the proof-of-concept that STAT3 is a critical mediator in promoting the hypoxia-induced acquisition of cancer stemness in TNBC. Targeting STAT3 in TNBC may be useful in overcoming chemoresistance and decreasing the risk of disease relapse.

MAIN OUTCOME MEASURE(S) Adm mRNA levels according to quantitative real-time polymerase chain reaction after activation of STAT3 by interleukin-6 (IL-6) in Ishikawa cells; immunohistochemistry for ADM in eutopic endometrial biopsies from women with endometriosis compared with healthy donors; and MR-proADM levels measured by commercial immunoassay in plasma from healthy women and women with endometriosis who subsequently underwent surgical resection of ectopic lesions. RESULT(S) Activation of STAT3 by IL-6 up-regulated Adm mRNA expression in Ishikawa cells. ADM protein levels were elevated in the eutopic endometrium of women with endometriosis. MR-proADM concentrations were higher in women with endometriosis but were not correlated with disease stage, corrected by surgery, or predictive of fertility outcome. CONCLUSION(S) MR-proADM may be able to serve as a biomarker of endometriosis, but it is unknown whether elevated MR-proADM levels are secondary to the estrogenic and inflammatory properties of endometriosis or an inciting pathogenic factor.

Han J, Puri RK. Analysis of the cancer genome atlas (TCGA) database identifies an inverse relationship between interleukin-13 receptor α1 and α2 gene expression and poor prognosis and drug resistance in subjects with glioblastoma multiforme. J Neurooncol 2017; 136:463-474. [PMID: 29168083 PMCID: PMC5805806 DOI: 10.1007/s11060-017-2680-9] [Citation(s) in RCA: 40] [Impact Index Per Article: 5.7] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/28/2017] [Accepted: 11/11/2017] [Indexed: 01/29/2023]
Abstract
Glioblastoma multiforme (GBM) is the most common primary brain tumor in adults. A variety of targeted agents are being tested in the clinic including cancer vaccines, immunotoxins, antibodies and T cell immunotherapy for GBM. We have previously reported that IL-13 receptor subunits α1 and α2 of IL-13R complex are overexpressed in GBM. We are investigating the significance of IL-13Rα1 and α2 expression in GBM tumors. In order to elucidate a possible relationship between IL-13Rα1 and α2 expression with severity and prognoses of subjects with GBM, we analyzed gene expression (by microarray) and clinical data available at the public The Cancer Genome Atlas (TCGA) database (Currently known as Global Data Commons). More than 40% of GBM samples were highly positive for IL-13Rα2 mRNA (Log2 ≥ 2) while only less than 16% samples were highly positive for IL-13Rα1 mRNA. Subjects with high IL-13Rα1 and α2 mRNA expressing tumors were associated with a significantly lower survival rate irrespective of their treatment compared to subjects with IL-13Rα1 and α2 mRNA negative tumors. We further observed that IL-13Rα2 gene expression is associated with GBM resistance to temozolomide (TMZ) chemotherapy. The expression of IL-13Rα2 gene did not seem to correlate with the expression of genes for other chains involved in the formation of IL-13R complex (IL-13Rα1 or IL-4Rα) in GBM. However, a positive correlation was observed between IL-4Rα and IL-13Rα1 gene expression. The microarray data of IL-13Rα2 gene expression was verified by RNA-Seq data. In depth analysis of TCGA data revealed that immunosuppressive genes (such as FMOD, CCL2, OSM, etc.) were highly expressed in IL-13Rα2 positive tumors, but not in IL-13Rα2 negative tumors. These results indicate a direct correlation between high level of IL-13R mRNA expression and poor patient prognosis and that immunosuppressive genes associated with IL-13Rα2 may play a role in tumor progression. These findings have important implications in understanding the role of IL-13R in the pathogenesis of GBM and potentially other cancers.

Abstract
Glioblastoma multiforme (GBM) is the most common primary intracranial tumor in adults and has poor prognosis. Diffuse infiltration into normal brain parenchyma, rapid growth, and the presence of necrosis are remarkable hallmarks of GBM. However, the effect of necrotic cells on GBM growth and metastasis is poorly understood at present. In this study, we examined the biological significance of necrotic tissues by exploring the molecular mechanisms underlying the signaling network between necrotic tissues and GBM cells. The migration and invasion of the GBM cell line CRT-MG was significantly enhanced by treatment with necrotic cells, as shown by assays for scratch wound healing and spheroid invasion. Incubation with necrotic cells induced IL-8 secretion in CRT-MG cells in a dose-dependent manner. In human GBM tissues, IL-8 positive cells were mainly distributed in the perinecrotic region, as seen in immunohistochemistry and immunofluorescence analysis. Necrotic cells induced NF-κB and AP-1 activation and their binding to the IL-8 promoter, leading to enhanced IL-8 production and secretion in GBM cells. Our data demonstrate that when GBM cells are exposed to and stimulated by necrotic cells, the migration and invasion of GBM cells are enhanced and facilitated via NF-κB/AP-1 mediated IL-8 upregulation.

Abstract
Cancer cell growth is complicated progression which is regulated and controlled by multiple factors including cell cycle, migration and apoptosis. In present study, we report that TADs, a novel derivative of taspine, has an essential role in resisting hepatocellular carcinoma growth (including arrest cell cycle) and migration, and inducing cell apoptosis. Our findings demonstrated that the TADs showed good inhibition on the hepatoma cell growth and migration, and good action on apoptosis induction. Using genome-wide microarray analysis, we found the down-regulated growth and apoptosis factors, and selected down-regulated genes were confirmed by Western blot. Knockdown of a checkpoint c-Myc by siRNA significantly attenuated tumor inhibition and apoptosis effects of TADs. Moreover, our results indicated TADs could simultaneously increase cyclin D1 protein levels and decrease amount of cyclin E, cyclin B1 and cdc2 of the cycle proteins, and also TADs reduced Bcl-2 expression, and upregulated Bad, Bak and Bax activities. In conclusion, these results illustrated that TADs is a key factor in growth and apoptosis signaling inhibitor, has potential in cancer therapy.
