[PMID: 36238156 PMCID: PMC9552700 DOI: 10.3389/fgene.2022.928407] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/26/2022] [Accepted: 09/01/2022] [Indexed: 11/17/2022] Open
Abstract
Background: Glioblastoma is a common malignant neuroepithelial neoplasm with poor clinical outcomes and limited treatment options. It is extremely important to search and confirm diverse hub genes that are effective in the advance and prediction of glioblastoma. Methods: We analyzed GSE50161, GSE4290, and GSE68848, the three microarray datasets retrieved from the GEO database. GO function and KEGG pathway enrichment analyses for differentially expressed genes (DEGs) were performed using DAVID. The PPI network of the DEGs was analyzed using the Search Tool for the Retrieval of Interacting Genes database and visualized by Cytoscape software. Hub genes were identified through the PPI network and a robust rank aggregation method. The Cancer Genome Atlas (TCGA) and the Oncomine database were used to validate the hub genes. In addition, a survival curve analysis was conducted to verify the correlation between the expression of hub genes and patient prognosis. Human glioblastoma cells and normal cells were collected, and then RT-PCR, Western blot, and immunofluorescence were conducted to validate the expression of the NDC80 gene. A cell proliferation assay was used to detect the proliferation of glioma cells. The effects of NDC80 expression on migration and invasion of GBM cell lines were evaluated by conducting scratch and transwell assays. Results: A total of 716 DEGs were common to all three microarray datasets, which included 188 upregulated DEGs and 528 downregulated DEGs. Furthermore, we found that among the common DEGs, 10 hub genes showed a high degree of connectivity. The expression of the 10 hub genes in TCGA and the Oncomine database was significantly overexpressed in glioblastoma compared with normal genes. Additionally, the survival analysis showed that the patients with low expression of six genes (BIR5C, CDC20, NDC80, CDK1, TOP2A, and MELK) had a significantly favorable prognosis (p < 0.01). We discovered that NDC80, which has been shown to be important in other cancers, also has an important role in malignant gliomas. The RT-PCR, Western blot, and immunofluorescence results showed that the expression level of NDC80 was significantly higher in human glioblastoma cells than in normal cells. Moreover, we identified that NDC80 increased the proliferation and invasion abilities of human glioblastoma cells. Conclusion: The six genes identified here may be utilized to form a panel of disease progression and predictive biomarkers of glioblastoma for clinical purposes. NDC80, one of the six genes, was discovered to have a potentially important role in GBM, a finding that needs to be further studied.

Abstract
Glioblastoma is the most common adult brain tumour, representing a high degree of malignancy. Transcription factors such as RUNX1 are believed to be involved in the malignancy of glioblastoma. RUNX1 functions as an oncogene or tumour suppressor gene with diverse target genes. Details of the effects of RUNX1 on the acquisition of malignancy in glioblastoma remain unclear. Here, we show that RUNX1 downregulates p21 by enhancing expressions of BIRC5 and PIF1, conferring anti-apoptotic properties on glioblastoma. A gene switch-off therapy using alkylating agent-conjugated pyrrole-imidazole polyamides, designed to fit the RUNX1 DNA groove, decreased expression levels of BIRC5 and PIF1 and induced apoptosis and cell cycle arrest via p21. The RUNX1-BIRC5/PIF1-p21 pathway appears to reflect refractory characteristics of glioblastoma and thus holds promise as a therapeutic target. RUNX gene switch-off therapy may represent a novel treatment for glioblastoma. Interfering with RUNX family proteins reduces glioblastoma growth in mice and reveals pathways involved in the maintenance of tumour growth.

[PMID: 35461228 PMCID: PMC9035256 DOI: 10.1186/s12885-022-09500-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 4.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 04/01/2021] [Accepted: 04/01/2022] [Indexed: 11/10/2022] Open
Abstract
Abstract
Background
Baculoviral IAP repeat containing 5 (BIRC5) is overexpressed and plays as a key regulator in the progression of various human carcinomas. The inflammatory tumor microenvironment (ITM) is closely associated with the development of cancers. However, the role of BIRC5 in penile cancer (PC) and the ITM-induced abnormal progression of PC is still obscure.
Methods
In this study, serum and tissues of patients with PC were recruited to evaluate the expression profile of BIRC5. We used PC cell lines (Penl1 and Penl2) and constructed a PC xenograft mice model to explore the effects of the silencing of BIRC5 on proliferation, migration, invasion and tumor growth, as well as survival of mice. Besides, interferon (IFN)-γ was utilized to mimic the ITM of PC cells.
Results
Our results showed that BIRC5 was dramatically upregulated in the serum and tissues of PC patients, as well as PC cell lines. Knockdown of BIRC5 inhibited the proliferation, migration and invasion of PC cells. Meanwhile, it suppressed PC xenograft tumor growth and improved mice survival. Moreover, IFN-γ significantly aggravated PC progression both in vivo and in vitro while the silencing of BIRC5 reversed these unfavorable effects.
Conclusions
Taken together, our data revealed that BIRC5 silencing inhibited aggravation of PC cell processes and tumor development induced by ITM. This suggested that BIRC5 may function as a diagnosis and therapy target of PC in the future.

Abstract
AIMS Glioblastoma (GB) is the most aggressive type of brain tumor. Rapid progression, active angiogenesis, and therapy resistance are major reasons for its high mortality. Elevated expression of members of the vascular endothelial growth factor (VEGF) family suggests that anti-VEGF therapies may be potent anti-glioma therapeutic approaches. Here, we evaluated the anti-tumor activity of cediranib, a pan inhibitor of the VEGF receptors, on GB cells. MATERIALS AND METHODS Anti-proliferative effects of cediranib were determined using MTT, crystal-violet staining, clonogenic and anoikis resistance assays. Apoptosis induction was assessed by Annexin V/PI staining and Western blot analysis and aggressive abilities of GB cells were investigated using cell migration/invasion assays and zymography. Small-interfering RNA (siRNA)-mediated Knockdown was used to study resistance mechanisms. The anti-proliferative and apoptotic effects of cediranib in combination with radiotherapy, temozolomide, bevacizumab were also evaluated using MTT, Annexin V/PI staining and Western blot analysis for cleaved PARP-1. KEY FINDINGS Cediranib reduced GB cell proliferation, induced apoptotic cell death and inhibited the aggressive abilities of GB cells. Cediranib synergistically increased the anti-proliferative and apoptotic effects of radiotherapy and bevacizumab and augmented the sensitivity of GB cells to temozolomide chemotherapy. In addition, knockdown of MET and AKT potentiated cediranib sensitivity in cediranib-resistant GB cells. SIGNIFICANCE These findings suggest that cediranib, alone or in combination with other therapeutics, is a promising strategy for the treatment of GB and provide a rationale for further investigation of the therapeutic potential of cediranib for the treatment of this fatal malignancy.

Abstract
Background:Rhazya stricta has been used as a folkloric medicinal herb for
treating various diseases such as diabetes, inflammatory disorders, and sore
throat. Several studies have revealed the potential of this plant as an
important source of phytochemicals with anticancer properties.
Objective: The present study was designed to isolate a novel
anticancer compound from Rhazya stricta and elucidate its
mechanism of action using genomics approach. Methods:Rhazya stricta leaves extract was prepared, and several
alkaloids were purified and characterized. These alkaloids were screened for
their anticancer potential. One of the alkaloids, termed as isopicrinine, showed
efficient cytotoxicity against MCF7 breast cancer cell line and was selected for
further analysis. RNA-Seq transcription profiling was conducted to identify the
affected genes and cellular pathways in MCF7 cells after treatment with
isopicrinine alkaloid. Results: In vitro studies revealed that
newly identified isopicrinine alkaloid possess efficient anticancer activity.
Exposure of MCF7 cells with isopicrinine affected the expression of various
genes involved in p53 signaling pathway. One of the crucial proapoptotic genes,
significantly upregulated in MCF7 after exposure to alkaloid, was
PUMA (p53 upregulated modulator of apoptosis), which is
involved in p53-dependent and -independent apoptosis. Moreover, exposure of
sublethal dose of isopicrinine alkaloid in breast cancer cell line led to the
downregulation of survivin, which is involved in negative regulation of
apoptosis. Besides, several genes involved in mitosis and cell proliferation
were significantly downregulated. Conclusion: In this article, we
report the determination of a new alkaloid isopicrinine from the aerial parts of
Rhazya stricta with anticancer property. This compound has
the potential to be developed as a drug for curing cancer.

Abstract
Glioblastoma (GBM) is one of the most deadly cancers and poorly responses to chemotherapies, such as temozolomide (TMZ). Dysregulation of intrinsic signaling pathways in cancer cells are often resulted by dysregulated tumor suppressive microRNAs (miRNAs). Previously, we found miR-138 as one of tumor suppressive miRNAs that were significantly down-regulated in GBM. In this study, we demonstrated that ectopic over-expression of miR-138 sensitizes GBM cells to the treatment of TMZ and increased apoptotic cell death. Mechanistically, miR-138 directly repressed the expression of Survivin, an anti-apoptotic protein, to enhance caspase-induced apoptosis upon TMZ treatment. Using an intracranial GBM xenograft mice model, we also showed that combination of miR-138 with TMZ increases survival rates of the mice compared to the control mice treated with TMZ alone. This study provides strong preclinical evidence of the therapeutic benefit from restoration of miR-138 to sensitize the GBM tumor to conventional chemotherapy.

Abstract
Dibutyl phthalate (DBP), a typical representative of phthalate esters (PAEs), is used as a plasticizer in various industrial applications and has been reported to be responsible for neurobehavioral changes. Despite mounting evidence showing that nimodipine (Nim) palys a neuropharmacological and psychopharmacological role in neurons, the attenuating effects of Nim on learning and memory impairment induced by DBP exposure remain unknown. Based on bioinformatics analysis we found that the biological processes affected by both DBP and Nim may involve the calcium signaling pathway, the MAPK signaling pathway and the apoptosis pathway. The results of an in vivo study confirmed that DBP affects the levels of Ca2+ -related proteins, up-regulates phosphorylated -ERK1/2 expression and results in hippocampal neuronal damage and apoptosis, whereas Nim as a Ca2+ antagonist, has a certain neuroprotective role to avoid these adverse effects. Our data suggest that Nim could be used to attenuate the learning and memory impairment in DBP-exposed mice, to down-regulate intracellular Ca2+ levels, subordinate the ERK1/2 pathway and attenuate apoptosis in hippocampal tissue.

[Effect and mechanism of vascular endothelial growth factor-A on pulmonary vascular remodeling in neonatal rats with hypoxic pulmonary hypertension]. ZHONGGUO DANG DAI ER KE ZA ZHI = CHINESE JOURNAL OF CONTEMPORARY PEDIATRICS 2021; 23.

Abstract
OBJECTIVE To study the role of vascular endothelial growth factor-A (VEGF-A) in pulmonary vascular remodeling in neonatal rats with hypoxic pulmonary hypertension (HPH) by regulating survivin (SVV). METHODS A total of 96 neonatal rats were randomly divided into three groups: HPH+VEGF-A group, HPH group, and control group. Each group was further randomly divided into 3-, 7-, 10-, and 14-day subgroups (n=8 in each subgroup). The neonatal rats in the HPH+VEGF-A and HPH groups were intratracheally transfected with adenoviral vectors with or without VEGF-A gene respectively. Those in the control group were given intratracheal injection of normal saline and were then fed under normoxic conditions. The direct measurement method was used to measure mean right ventricular systolic pressure (RVSP). Hematoxylin-eosin staining was used to observe the morphological changes of pulmonary vessels under a light microscope and calculate the percentage of media wall thickness (MT%) and the percentage of media wall cross-sectional area (MA%) in the pulmonary arterioles. Immunohistochemistry was used to measure the expression levels of VEGF-A and SVV in lung tissue. RESULTS The HPH group had a significantly higher mean RVSP than the control and HPH+VEGF-A groups at each time point (P < 0.05). Pulmonary vascular remodeling occurred in the HPH group on day 7 of hypoxia, while it occurred in the HPH+VEGF-A group on day 10 of hypoxia. On day 7 of hypoxia, the HPH group had significantly higher MT% and MA% than the control and HPH+VEGF-A groups (P < 0.05). On days 10 and 14 of hypoxia, the HPH and HPH+VEGF-A groups had significantly higher MT% and MA% than the control group (P < 0.05). The HPH and HPH+VEGF-A groups had significantly higher expression of VEGF-A than the control group at each time point (P < 0.05). On days 3 and 7 of hypoxia, the HPH+VEGF-A group had significantly higher expression of VEGF-A than the HPH group (P < 0.05). On day 14 of hypoxia, the HPH group had significantly higher expression of SVV than the control group (P < 0.05). The HPH+VEGF-A group had significantly higher expression of SVV than the control group at each time point (P < 0.05). On days 3 and 7 of hypoxia, the HPH+VEGF-A group had significantly higher expression of SVV than the HPH group (P < 0.05). CONCLUSIONS Prophylactic intratracheal administration of exogenous VEGF-A in neonatal rats with HPH can inhibit pulmonary vascular remodeling and reduce pulmonary arterial pressure by upregulating the expression of SVV in the early stage of hypoxia. This provides a basis for the interventional treatment of pulmonary vascular remodeling in neonatal HPH.

Abstract
BACKGROUND The evasion from apoptosis is a common strategy adopted by most tumors, and inhibitors of apoptosis proteins (IAPs) are among the most studied molecular and therapeutic targets. BIRC3 (cellular IAP2) and BIRC5 (survivin) are two of the eight members of the human IAPs family. This family is characterized by the presence of the baculoviral IAP repeat (BIR) domains, involved in protein-protein interactions. In addition to the BIR domains, IAPs also contain other important domains like the C-terminal ubiquitin-conjugating (UBC) domain, the caspase recruitment (CARD) domain and the C-terminal Ring zinc-finger (RING) domain. MAIN BODY BIRC3 and BIRC5 have been characterized in some solid and hematological tumors and are therapeutic targets for the family of drugs called "Smac mimetics". Many evidences point to the pro-survival and antiapoptotic role of BIRC3 in cancer cells, however, not all the data are consistent and the resulting picture is heterogeneous. For instance, BIRC3 genetic inactivation due to deletions or point mutations is consistently associated to shorter progression free survival and poor prognosis in chronic lymphocytic leukemia patients. BIRC3 inactivation has also been associated to chemoimmunotherapy resistance. On the contrary, the progression from low grade gliomas to high grade gliomas is accompanied by BIRC3 expression increase, which bears relevant prognostic consequences. Due to the relationship between BIRC3, MAP3K14 and the non-canonical NF-kB pathway, BIRC3 inactivation bears consequences also on the tumor cells relying on NF-kB pathway to survive. BIRC5, on the contrary, is commonly considered an anti-apoptotic molecule, promoting cell division and tumor progression and it is widely regarded as potential therapeutic target. CONCLUSIONS The present manuscript collects and reviews the most recent literature concerning the role played by BIRC3 and BIRC5 in cancer cells, providing useful information for the choice of the best therapeutic targets.

Abstract
OBJECTIVE The object of this study was to clarify the expression characteristics and prognostic value of survivin in skull base chordomas. METHODS In this retrospective study, the authors measured the expression of survivin at the mRNA level in 81 samples from 71 patients diagnosed with skull base chordomas at their hospital in the period from July 2005 to January 2015. Clinical data collection, follow-up, and survival analyses were performed, and correlations were analyzed. RESULTS Of the 71 patients, 50 had primary chordomas with a mean survivin expression level of 1.09; the other 21 patients had recurrent chordomas with a mean survivin expression level of 2.57, which was 2.36 times higher than the level in the primary chordoma patients (p < 0.001, Mann-Whitney U-test). In addition, an analysis of 18 paired samples derived from 9 patients showed that the expression level of survivin was 2.62 times higher in recurrent tumors than in primary tumors (p = 0.002, paired t-test). The Spearman rank correlation coefficient method showed that the expression level of survivin was positively correlated with the mean ratio of tumor signal intensity to the signal intensity of surrounding brainstem on T1-weighted sequences (RT1; rs = 0.274, p = 0.021) and was negatively correlated with the mean ratio of tumor signal intensity to the signal intensity of surrounding brainstem on T2-weighted sequences (RT2; rs = -0.389, p = 0.001). A multivariate Cox proportional-hazards model suggested that pathology (p = 0.041), survivin expression level (p = 0.018), preoperative Karnofsky Performance Status (KPS; p = 0.012), and treatment history (p = 0.009) were independent prognostic factors for tumor progression. Survivin expression level (p = 0.008), preoperative KPS (p = 0.019), tumor diameter (p = 0.027), and intraoperative blood loss (p = 0.015) were independent prognostic factors for death. CONCLUSIONS Survivin expression level and preoperative KPS were independent significant prognostic factors for tumor progression and death in skull base chordoma patients. Recurrent skull base chordomas and chordomas with high RT1 and low RT2 were likely to have high survivin expression. Other independent risk factors related to tumor progression included conventional pathology and treatment history, whereas additional mortality-related risk factors included larger tumor diameter and greater intraoperative blood loss.

Abstract
PURPOSE Oligodendrocytes (OLGs) damage and myelin distraction is considered as a critical step in many neurological disorders especially multiple sclerosis (MS). Cuprizone (cup) animal model of MS targets OLGs degeneration and frequently used to the mechanistic understanding of de- and remyelination. The aim of this study was exploring the effects of metformin on the OLGs regeneration, myelin repair and profile of neurotrophic factors in the mice brain after cup-induced acute demyelination. METHODS Mice (C57BL/6 J) were fed with chow containing 0.2% cup for 5 weeks to induce specific OLGs degeneration and acute demyelination. Next, the cup was withdrawn to allow one-week recovery (spontaneous remyelination). At the end of this period, mature OLGs markers, myelin-associated neurite outgrowth inhibitor protein A (NogoA), premature specific OLGs transcription factor (Olig2), anti-apoptosis marker (survivin), neurotrophic factors, and AMPK activation were monitored in the presence or absence of metformin (50 mg/kg body weight/day) in the corpus callosum (CC). RESULTS Our finding indicated that consumption of metformin during the recovery period potentially induced an active form of AMPK (p-AMPK) and promoted repopulation of mature OLGs (MOG+ cells, MBP+ cells) in CC through up-regulation of BDNF, CNTF, and NGF as well as down-regulation of NogoA and recruitment of Olig2+ precursor cells. CONCLUSIONS This study for the first time reveals that metformin-induced AMPK, a master regulator of energy homeostasis, activation following toxic demyelination could potentially accelerate regeneration and supports spontaneous demyelination. These findings suggest the development of new therapeutic strategies based on AMPK activation for MS in the near future.

Abstract
Improvement of radioiodine accumulation in non-thyroidal tumors by transfecting the sodium iodide symporter (NIS) gene has been successfully investigated in many studies. However, regarding the uncertain iodine influx and efflux efficiencies in different cells, the optimal imaging time by radioiodine following NIS gene transport remains unclear. This study aimed to investigate the serial expression of NIS under control of survivin promoter in prostate cancer PC-3 cells and xenografts by adenoviral vector (Ad-Sur-NIS), and determine the optimal imaging time for radioiodine application. In vitro, the 125I accumulation in Ad-Sur-NIS-infected PC-3 cells was 44 times higher than that in control cells (P<0.05). Moreover, the expression efficiency of NIS reached a peak at 48 h post transfection, at which a 1.9-fold or 1.4-fold increase of 125I accumulation was found compared with 24 h or 72 h. In the clonogenic assay, the cell inhibition rates induced by 131I were 93.4 ± 11.2% in Ad-Sur-NIS and 71.8 ± 10.1% in Ad-NIS infected cells, both of which were significantly higher than that in Ad-Sur-GFP infected cells (10.9 ± 1.9%, P<0.05). In in vivo studies, the 131I uptake of tumor-to-muscle ratios were more prominent on day 2 (15.23 ± 4.55) and day-9 (9.78 ± 2.34) compared to the day 16 (1.29 ± 0.49), which showed a gradual reduction (P<0.05). Therefore, the Ad-Sur-NIS transfection allowed PC-3 tumor imaging by iodine-131 with an optimal time no later than 9 days post-transfection.

Abstract
Background Survivin, belonging to the inhibitor of apoptosis (IAP) gene family, is abundantly expressed in tumors. It has been hypothesized that Survivin facilitates carcinogenesis by inhibition of apoptosis resulting in improved survival of tumorigenic progeny. Additionally, Survivin plays an essential role during mitosis. Together with its molecular partners Aurora B, Borealin and inner centromere protein it secures bipolar chromosome segregation. However, whether increased Survivin levels contribute to progression of tumors by inducing chromosomal instability remains unclear. Methods We overexpressed Survivin in U251-MG, SVGp12, U87-MG, HCT116 and p53-deficient U87-MGshp53 and HCT116p53−/− cells. The resulting phenotype was investigated by FACS-assisted cell cycle analysis, Western Blot analysis, confocal laser scan microscopy, proliferation assays, spectral karyotyping and in a U251-MG xenograft model using immune-deficient mice. Results Overexpression of Survivin affected cells with knockdown of p53, cells harboring mutant p53 and SV40 large T antigen, respectively, resulting in the increase of cell fractions harboring 4n and >4n DNA contents. Increased γH2AX levels, indicative of DNA damage were monitored in all Survivin-transduced cell lines, but only in p53 wild type cells this was accompanied by an attenuated S-phase entry and activation of p21waf/cip. Overexpression of Survivin caused a DNA damage response characterized by increased appearance pDNA-PKcs foci in cell nuclei and elevated levels of pATM S1981 and pCHK2 T68. Additionally, evolving structural chromosomal aberrations in U251-MG cells transduced with Survivin indicated a DNA-repair by non-homologous end joining recombination. Subcutaneous transplantation of U251-MG cells overexpressing Survivin and mycN instead of mycN oncogene alone generated tumors with shortened latency and decreased apoptosis. Subsequent SKY-analysis of Survivin/mycN-tumors revealed an increase in structural chromosomal aberrations in cells when compared to mycN-tumors. Conclusions Our data suggest that increased Survivin levels promote adaptive evolution of tumors through combining induction of genetic heterogeneity with inhibition of apoptosis.

Elucidating respective functions of two domains BIR and C-helix of human IAP survivin for precise targeted regulating mitotic cycle, apoptosis and autophagy of cancer cells.

Abstract
Survivin was the smallest member of the IAP family, which was over expressed in many different cancers, and considered to be a promising hot target for cancer therapy, and our previous study demonstrated that multiple dominant negative mutants from full-length survivin could have many complex effects on cancer cells, such as cell cycle, apoptosis, and autophagy. But it was not yet known what role the two main domains played in those functions, which would be very important for the design of targeted anticancer drugs and for the interpretation of their molecular mechanisms. In this study, based on preparation the two parts (BIR domain and CC domain) of survivin by genetic engineering and cell characterization assay, we discovered that BIR (T34A)-domain peptide could inhibit Bcap-37 cells growth in a dose- and time-dependent manner, increase the proportion of G2/M phase, and induce caspase-dependent apoptosis via the mitochondrial pathway. While CC (T117A)-domain peptide increased the proportion of S-phase cells and increased the level of the autophagy marker protein LC3B significantly. These further experiments confirmed that TAT-BIR (T34A) peptide could be used to inhibit cell proliferation, promote apoptosis, and block mitosis, and TAT-CC (T117A) peptide showed mainly to promote autophagy, process of DNA replication, and mitosis to breast cancer cells. This research will lay the foundation for interpreting the multifunction mechanism of survivin in cell fates, further make senses in developing the anticancer drugs targeting it precisely and efficiently.
