[PMID: 36035172 PMCID: PMC9400172 DOI: 10.3389/fgene.2022.953739] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Grants] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/26/2022] [Accepted: 06/30/2022] [Indexed: 11/13/2022] Open
Abstract
Background:β-Catenin has been recently identified as a promising novel therapeutic target and prognostic marker in different types of cancer. Here, we conduct a meta-analysis to better clarify the correlation between β-Catenin expression and survival outcomes in nasopharyngeal carcinoma (NPC) patients.Patients/methods: Following the Preferred Reporting Items or Systematic Reviews Meta Analyses (PRISMA) 2020 guidelines, the PubMed, Embase, Web of Science, Cochrane Library, Chinese National Knowledge Infrastructure (CNKI) and Wanfang databases were systematically searched for relevant studies to explore the prognostic significance of β-Catenin in NPC. Pooled hazards ratios (HRs) and 95% confidence intervals (CIs) were used to estimate the association of β-Catenin expression with survival outcomes in NPC patients. Odd ratios (ORs) and 95% CIs for clinicopathological characteristics were also statistically analyzed.Results: Eight studies involving 1,179 patients with NPC were ultimately included in the meta-analysis. Pooled analysis indicated that elevated β-Catenin expression was significantly associated with poor OS (HR = 2.45, 95% CIs: 1.45–4.16, p = 0.001) and poor DFS/PFS (HR 1.79, 95% CIs: 1.29–2.49, p = 0.000). Furthermore, β-cadherin was signifcantly associated with higher TMN stages (OR = 5.10, 95% CIs 2.93–8.86, p = 0.000), clinical stages (OR = 5.10, 95% CIs 2.93–8.86, p = 0.000) and lymph node metastasis (LNM) (OR = 5.01, 95% CIs 2.40–10.44, p = 0.000).Conclusions: This study demonstrated that for NPC, patients with elevated β-Catenin expression are more likely to have poor survival.

Abstract
Background: Similar to that in other malignant tumors, distant metastasis is one of the most important causes of poor prognosis in nasopharyngeal carcinoma (NPC). However, the genetic hallmarks and networks that regulate the distant metastasis of NPC are not fully understood. Methods: In this study, we performed high-throughput screening of mRNA expression profiles in 92 NPC samples collected from 3hospitals and detected the mRNA expression levels of 31,503 genes in these samples. Gene functional enrichment analyses were performed using gene set enrichment analysis (GSEA). Least absolute shrinkage and selection operator (LASSO) was applied to select prognostic genes and a Cox proportional hazards regression model including these genes was constructed to predict prognosis. The Kaplan-Meier curve and time-dependent receiver operating characteristic (ROC) curve were plotted to assess the performance of this model. Univariate and multivariate analyses were performed using the Cox proportion hazard model to test the independence of prognostic effect of gene model and other clinical features. Results: A total of 1837 differentially expressed genes between patients with and without distant metastasis were identified in the training cohort, including 869 upregulated genes and 968 downregulated genes. Six gene sets, including the Wnt/β catenin signaling pathway, hedgehog (Hh) signaling pathway, Notch signaling pathway, mitotic spindle, apical surface, and estrogen response late, were enriched in patients with distant metastasis. A four-gene signature model was constructed in the training cohort, and according to the time-dependent ROC curve, this model had certain accuracy in predicting distant metastasis-free survival (DMFS) in both the training and validation cohorts. Conclusion: We developed a four-gene signature model that can evaluate the distant metastasis risk of NPC patients and may also provide novel therapeutic targets for NPC treatment in the near future.

Abstract
Sepsis is a disease induced by severe systemic inflammation and contributes to multiple acute organic dysfunctions. It is reported that disrupted blood-brain barrier (BBB) integrity is involved in sepsis-associated encephalopathy (SAE), which can be alleviated by repairing the damaged tight junction structure. Cabergoline is a specific dopamine D2 receptor agonist developed to treat Parkinson’s disease and hyperprolactinemia and is reported to exert promising anti-inflammatory properties. The present study aimed to explore the beneficial effect of Cabergoline for the treatment of sepsis. In the animal experiments, mice were separated into 4 groups: sham, LPS (5 mg/kg), Cabergoline (0.1 mg/kg/day), and Cabergoline+LPS. We found that the increased neurological deficits, disrupted BBB integrity, elevated production of inflammatory factors, and declined expression level of zonula occludens-1 (ZO-1) were observed in lipopolysaccharide (LPS)-treated mice, all of which were significantly reversed by the administration of Cabergoline. In the in vitro model, human brain microvascular endothelial cells (HBMECs) were challenged with 1 µg/mL LPS in the presence or absence of Cabergoline (10, 20 μM) for 24 hours. The elevated cell permeability Papp value of fluorescein disodium across the HBMECs monolayer and declined trans-endothelial electrical resistance (TEER) in the LPS-treated HBMECs were significantly alleviated by Cabergoline, accompanied by the upregulation of ZO-1. In addition, wnt1 and β-catenin were found downregulated, which was reversed by Cabergoline. Importantly, the protective benefits of Cabergoline were all abolished by the overexpression of Dickkopf 3 (DKK3). Taken together, our data reveal that Cabergoline possessed a protective effect on BBB integrity against LPS.

Abstract
BACKGROUND Members of the Wnt signaling pathway have been shown to play a role in nasopharyngeal carcinoma (NPC) progression. AIM The purpose of this study was to investigate WNT8B protein expression in NPC patients using tissue microarray (TMA) analysis and to evaluate its correlation with patient survival and clinical parameters. METHODS A total of 82 NPC cases, together with six normal nasopharyngeal tissue samples, were targeted to construct the TMA blocks. The WNT8B protein expression was evaluated by immunohistochemistry and its correlation to the clinicopathological features was investigated. RESULTS Sixty-two of 82 (75.6%) cases exhibited high WNT8B protein expression while 20/82 (24.4%) cases appeared to have low WNT8B expression. The univariate analysis revealed that systemic metastasis was associated with patient 5-year survival. The multivariate Cox proportional hazard regression analysis showed that WNT8B expression and systemic metastasis were significantly associated with the survival of NPC patients. Furthermore, there was no correlation found between the WNT8B protein expression and other clinicopathological parameters. CONCLUSION Our results suggest that the expression of WNT8B is associated with NPC patients' survival and could serve as an independent prognostic factor for NPC patients.

MicroRNA-384 inhibits nasopharyngeal carcinoma growth and metastasis via binding to Smad5 and suppressing the Wnt/β-catenin axis. Cytotechnology 2021; 73:203-215. [PMID: 33911345 PMCID: PMC8035371 DOI: 10.1007/s10616-021-00458-3] [Citation(s) in RCA: 3] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2020] [Accepted: 02/05/2021] [Indexed: 01/10/2023] Open
Abstract
Nasopharyngeal carcinoma (NPC) is a major otorhinolaryngological disease with limited effective therapeutic options. This work focused on the function of microRNA-384 (miR-384) on the NPC pathogenesis and the molecules involved. miR-384 expression in cancer tissues and cells was detected. Gain- and loss-of-functions of miR-384 were performed to identify its role in NPC progression. The target mRNA of miR-384 was predicted on an online system and validated through a luciferase reporter assay. The activity of Wnt/β-catenin signaling was detected. Consequently, miR-384 was found to be poorly expressed in NPC tissues and cell lines and was linked to unfavorable survival rates in patients. Overexpression of miR-384 in 6-10B cells suppressed growth, migration, invasion and resistance to apoptosis of cells, but inverse trends were presented in C6661 cells where miR-384 was downregulated. miR-384 targeted Smad5 mRNA. Upregulation of Smad5 counteracted the roles of miR-384 mimic in cells. The NPC-inhibiting effects of miR-384 mimic were also blocked by Wnt/β-catenin activation. To conclude, miR-384 targets Smad5 and inactivates the Wnt/β-catenin pathway, which exerts a suppressing role in NPC cell behaviors as well as tumor growth in vivo. The findings may offer novel thoughts into NPC therapy. Supplementary Information The online version contains supplementary material available at 10.1007/s10616-021-00458-3.

Abstract
Dkk3 has been discovered during comparison of immortalized and parental cells. Its expression has been shown to reduce colony formation and induce apoptosis of cancer cells, acting as a tumor suppressor. Herein, we demonstrate that Dkk3 overexpression or protein treatment may inhibit colorectal cancer cell proliferation, migration, and invasion and that they may promote apoptosis and G2 phase arrest with hypoexpression of Bcl-2, cdc25B, cdc25c, N-cadherin, slug, and twist and hyperexpression of Bax and E-cadherin. This effect is consistent with that of recombinant Dkk3 exposure and blocked with anti-Dkk3 antibody. Dkk3 deletion in intestinal cells was not associated with the emergence of epithelial lesions; however, adenoma emerged after sodium desoxycholate treatment. At both mRNA and protein levels, Dkk3 expression was higher in normal than in cancer tissues (p<0.05). Dkk3 mRNA expression was negatively associated with its promoter methylation, growth pattern, differentiation, and favorable prognosis in the patients with colorectal cancer (p<0.05). Dkk3-related signal pathways in colorectal cancer included those of cellular adhesion and migration, melanogenesis, chemokine, Hedgehog, JAK-STAT, TOLL-like receptor, TGF-β, MAPK, and calcium signaling (p<0.05). These findings indicate that Dkk3 expression levels can help assess cancer aggressiveness and patient prognosis. It might also suppress aggressive phenotypes and tumorigenesis as a molecular target in gene therapy.

Abstract
Down-regulated lncRNA AC061961.2 in dilated cardiomyopathy (DCM) patients was previous reported. Whether AC061961.2 has regulatory effect on DCM still need exploration. Here, we tried to investigate the effect of AC061961.2 on DCM. After DCM model rat was established through injecting Adriamycin, left ventricular end-diastolic diameter (LVEDD), left ventricular end-systolic diameter (LVESD), left ventricular ejection fraction (LVEF), and left ventricular fractional shortening (LVFS) were measured by echocardiography. Histopathological changes and apoptosis were detected by hematoxylin-eosin, Masson staining, and TUNEL. After cardiomyocytes were isolated and identified by immunofluorescence, DCM cell model was established by injecting adriamycin. After transfected with overexpressed-AC061961.2 plasmids, cell apoptosis was detected by flow cytometry. The expressions of AC061961.2, β-catenin, Axin2, c-Myc, CRP78, CHOP, Caspase-3, Bcl-2, and Bax in cardiomyocytes and heart tissues were detected by RT-qPCR or western blot. LVEDD and LVESD were increased while LVEF and LVFS were decreased in DCM rats. The histopathological of heart tissues showed a typical sign of DCM. Apoptosis were increased in heart tissues of DCM rats. In DCM rats, the expressions of AC061961.2, β-catenin, Axin2, c-Myc, and Bcl-2 were decreased, the expressions of CRP78, CHOP, Caspase-3, and Bax were increased. After the overexpression of AC061961.2, levels of β-catenin, Axin2, c-Myc, and Bcl-2 were increased, while levels of CRP78, CHOP, Caspase-3, and Bax were decreased, compared with that in DCM cardiomyocytes. LncRNA AC061961.2 overexpression inhibited endoplasmic reticulum stress induced apoptosis in DCM rats and cardiomyocytes via activating Wnt/β-catenin pathway.

Abstract
Nasopharyngeal carcinoma (NPC) is a malignant epithelial carcinoma of the head and neck region which mainly distributes in southern China and Southeast Asia and has a crucial association with the Epstein-Barr virus. Based on epidemiological data, both incidence and mortality of NPC have significantly declined in recent decades grounded on the improvement of living standard and medical level in an endemic region, in particular, with the clinical use of individualized chemotherapy and intensity-modulated radiotherapy (IMRT) which profoundly contributes to the cure rate of NPC patients. To tackle the challenges including local recurrence and distant metastasis in the current NPC treatment, we discussed the implication of using targeted therapy against critical molecules in various signal pathways, and how they synergize with chemoradiotherapy in the NPC treatment. Combination treatment including targeted therapy and IMRT or concurrent chemoradiotherapy is presumably to be future options, which may reduce radiation or chemotherapy toxicities and open new avenues for the improvement of the expected functional outcome for patients with advanced NPC.

Abstract
Nasopharyngeal carcinoma (NPC) is a common malignant tumor in Southern China and Southeast Asia. In this study, we found that Leucine rich repeat containing G protein-coupled receptor 5 (Lgr5) was highly expressed in NPC tissues and marked NPC stem cells. Lgr5high tumors showed differential transcriptional landscape compared to Lgr5not high tumors. Lgr5 expression was associated with the clinicopathologic features in NPC and was able to regulate the stemness and viability of NPC cell line CNE1 and HNE1. Meanwhile, the migration, invasion and epithelial-mesenchymal transition (EMT) was modulated by Lgr5 via Wnt/β-catenin signaling pathway. Furthermore, Lgr5 could regulate the sensitivity of NPC cells to chemotherapy drugs. Xenografted tumors from Lgr5-overexpressed CNE1 cells showed stronger tumor forming capacity and higher expression level of stem cell markers. Thus, we characterized previously unidentified role of Lgr5 in NPC cells, potential serving as a NPC stem cell biomarker and a therapeutic target against NPC.

Abstract
Long non-coding RNAs (lncRNAs) play an important regulatory role in mammalian fecundity. Currently, most studies are primarily concentrated on ovarian lncRNAs, ignoring the influence of uterine lncRNAs on the fecundity of female sheep. In this study, we found a higher density of uterine glands and endometrial microvessel density (MVD) in high prolificacy group of Hu sheep compared to low prolificacy groups (p < 0.05) as well as an increased level of serum placental growth factor (PLGF). Hundreds of differentially expressed (DE) lncRNAs were identified in Hu sheep with different fecundity by RNA sequencing (RNA-seq), and their targets were enriched in some signaling pathways involved in endometrial functions, such as the estrogen signaling pathway, nuclear factor kappa B (NF-κB) signaling pathway, oxytocin signaling pathway, and Wnt signaling pathway. Furthermore, the underlying mechanisms of competitive endogenous RNA (ceRNA) of lncRNA366.2-miR-1576- WNT6 were determined by bioinformatics analysis. Functionally, our results indicated that lncRNA366.2 promoted endometrial epithelial cell (EEC) proliferation, migration, and growth factor expression by sponging miR-1576 to upregulate WNT6 expression and activate the Wnt/β-catenin pathway. Taken together, our research indicated the regulatory mechanism of the lncRNA366.2-miR-1576-WNT6 in EEC proliferation and migration. Furthermore, this study provides a new theoretical reference for the identification of candidate genes related to fecundity.

Abstract
Fluoride (F) is capable of promoting abnormal proliferation and differentiation in primary cultured mouse osteoblasts (OB cells), although the underlying mechanism responsible remains rare. This study aimed to explore the roles of wingless and INT-1 (Wnt) signaling pathways and screen appropriate doses of calcium (Ca2+) to alleviate the sodium fluoride (NaF)-induced OB cell toxicity. For this, we evaluated the effect of dickkopf-related protein 1 (DKK1) and Ca2+ on mRNA levels of wingless/integrated 3a (Wnt3a), low-density lipoprotein receptor-related protein 5 (LRP5), dishevelled 1 (Dv1), glycogen synthase kinase 3β (GSK3β), β-catenin, lymphoid enhancer binding factor 1 (LEF1), and cellular myelocytomatosis oncogene (cMYC), as well as Ccnd1 (Cyclin D1) in OB cells challenged with 10-6 mol/L NaF for 24 h. The demonstrated data showed that F significantly increased the OB cell proliferation rate. Ectogenic 0.5 mg/L DKK1 significantly inhibited the proliferation of OB cells induced by F. The mRNA expression levels of Wnt3a, LRP5, Dv1, LEF1, β-catenin, cMYC, and Ccnd1 were significantly increased in the F group, while significantly decreased in the 10-6 mol/L NaF + 0.5 mg/L DKK1 (FY) group. The mRNA expression levels of Wnt3a, LRP5, β-catenin, and cMYC were significantly decreased in the 10-6 mol/L NaF + 2 mmol/L CaCl2 (F+CaII) group. The protein expression levels of Wnt3a, Cyclin D1, cMYC, and β-catenin were significantly increased in the F group, whereas they were decreased in the F+CaII group. However, the mRNA and protein expression levels of GSK3β were significantly decreased in the F group while significantly increased in the F+CaII group. In summary, F activated the canonical Wnt/β-catenin pathway and changed the related gene expression and β-catenin protein location in OB cells, promoting cell proliferation. Ca2+ supplementation (2 mmol/L) reversed the expression levels of genes and proteins related to the canonical Wnt/β-catenin pathway.
