Abstract Background The aim of this study was to investigate the prognostic value of arginase-1 (Arg-1) and glypican-3 (GPC-3) in patients with intrahepatic cholangiocarcinoma (ICC). Methods Two hundred and thirty-seven patients with ICC were included in this study. All patients had undergone radical surgery and had complete clinical information. Immunohistochemistry was used to assess the levels of Arg-1 and GPC-3 in ICC tissues. Univariate and multivariate analyses were conducted to identify independent risk factors in ICC. The relationship between Arg-1 and GPC-3 levels and patient survival was determined using the Kaplan-Meier method. Results High Arg-1 and GPC-3 expression levels were associated with poor prognosis in patients with ICC, and they could be as new prognostic biomarkers in ICC. Conclusion Arg-1 and GPC-3 can serve as independent prognostic biomarkers in ICC.

Osteosarcoma (OS) often occurs in children and often undergoes metastasis, resulting in lower survival rates. Information on the complexity and pathogenic mechanism of OS is limited, and thus, the development of treatments involving alternative molecular and genetic targets is hampered. We categorized transcriptome data into metastasis and nonmetastasis groups, and 400 differential RNAs (230 messenger RNAs (mRNAs) and 170 long noncoding RNAs (lncRNAs)) were obtained by the edgeR package. Prognostic genes were identified by performing univariate Cox regression analysis and the Kaplan–Meier (KM) survival analysis. We then examined the correlation between the expression level of prognostic lncRNAs and mRNAs. Furthermore, microRNAs (miRNAs) corresponding to the coexpression of lncRNA-mRNA was predicted, which was used to construct a competitive endogenous RNA (ceRNA) regulatory network. Finally, multivariate Cox proportional risk regression analysis was used to identify hub prognostic genes. Three hub prognostic genes (ABCG8, LOXL4, and PDE1B) were identified as potential prognostic biomarkers and therapeutic targets for OS. Furthermore, transcriptions factors (TFs) (DBP, ESX1, FOS, FOXI1, MEF2C, NFE2, and OTX2) and lncRNAs (RP11-357H14.16, RP11-284N8.3, and RP11-629G13.1) that were able to affect the expression levels of genes before and after transcription were found to regulate the prognostic hub genes. In addition, we identified drugs related to the prognostic hub genes, which may have potential clinical applications. Immunohistochemistry (IHC) and quantitative real-time polymerase chain reaction (qRT-PCR) confirmed that the expression levels of ABCG8, LOXL4, and PDE1B coincided with the results of bioinformatics analysis. Moreover, the relationship between the hub prognostic gene expression and patient prognosis was also validated. Our study elucidated the roles of three novel prognostic biomarkers in the pathogenesis of OS as well as presenting a potential clinical treatment for OS.

Abstract Background It is yet a mystery whether dendritic cells (DCs) contact cancer stem cells (CSCs) and uptake CSC antigens in intrahepatic cholangiocarcinoma (ICC). The aim of this study was to examine the histological relationship between tumour cells expressing CSC markers and DCs infiltrating ICC. In addition, clinicopathological factors, including progression-free survival (PFS) and overall survival (OS), were compared between cases with many and few CSC marker-positive cells. Materials and methods Resected tissue sections of 22 cases with ICC were used for immunostaining to detect DC infiltration into ICC tumour nests positive for CD1a, DC-SIGN, DEC205, DC-LAMP, and CD123 and to detect ICC tumour cells positive for CSC markers such as CD44v9, EpCAM, and Sox9. The relationship between the number of CSC marker-positive cells and ICC clinicopathological factors was examined by Kaplan-Meier method and univariate and multivariate analyses using the Cox proportional hazards model. Results CD1a+ immature DCs infiltrated ICC tumour nests significantly more than the other types of DCs. Furthermore, they were frequently localized within CD44v9− and EpCAMhigh ICC tumour nests. According to Kaplan-Meier method, PFS and OS were longer in the Sox9high group than in the Sox9low group, and according to both univariate and multivariate analyses, Sox9 expression was an independent factor. Conclusion The present study first demonstrated that CD1a+ immature DCs frequently infiltrated CD44v9− and EpCAMhigh ICC tumour nests, suggesting the possibility of cell-to-cell contact between epithelial type immature DCs and CSCs in ICC. Furthermore, it was suggested that Sox9 expression in ICC may be a prognostic factor.

551 Background: Inflammatory response plays an important role in the pathogenesis of cancer. Some evidence has suggested that elevations in the neutrophil-to-lymphocyte ratio (NLR) and platelet-to-lymphocyte ratio (PLR) are associated with decreased survival in various types of cancer. In this study, we aimed to evaluate the prognostic value of the NLR and PLR in patients with colorectal cancer (CRC). Methods: Between August 1995 and December 2010, medical records from a total of 2,004 patients with CRC were retrospectively reviewed. The values of simple inflammatory markers including NLR and PLR in predicting the long-term outcomes of these patients were evaluated using Kaplan-Meier curves and multivariate Cox regression models. Results: The median follow-up duration was 42 months (interquartile range, 19 – 69). The estimation of NLR and PLR was based on the time of diagnosis. In multivariate Cox regression analysis, high NLR ( ≥ 2.6) [hazard ratio (HR) 2.251, 95% confidence interval (CI) 1.570-3.228, p < 0.001] and high PLR ( ≥ 155) [HR 1.473, 95% CI 1.019 – 2.128, p = 0.039] were independent risk factors predicting poor overall survival (OS) in CRC patients. Combined high NLR and PLR was also an independent risk factor predicting poor OS in patients with CRC [HR 2.316, 95% CI 1.529 – 3.508, p < 0.001]. Conclusions: In this study, we identified that high NLR ( ≥ 2.6), high PLR ( ≥ 155), and combined high NLR and PLR are useful prognostic factors to predict OS in CRC patients.

Data regarding expression levels of AHNAK2 in bladder cancer (BCa) have been very scarce. We retrospectively reviewed clinical data including clinicopathological features in 120 patients who underwent radical cystectomy (RC) for BCa. The expression levels of AHNAK2 in the specimens obtained by RC were classified as low expression (LE) or high expression (HE) by immunohistochemical staining. Statistical analyses were performed to compare associations between the two AHNAK2 expression patterns and the prognoses in terms of recurrence-free survival (RFS) and cancer-specific survival (CSS). A Kaplan–Meier analysis showed that patients with HE had a significantly worse RFS and CSS than those with LE (hazard ratio [HR]: 1.78, 95% confidence interval [CI]: 1.02–2.98, p = 0.027 and HR: 1.91, 95% CI: 1.08–3.38, p = 0.023, respectively). In a multivariate analysis, independent risk factors for worse RFS and CSS were shown as HE (HR: 1.96, 95% CI: 1.08–3.53, p = 0.026 and HR: 2.22, 95% CI: 1.14–4.31, p = 0.019, respectively) and lymph node metastasis (HR: 2.04, 95% CI: 1.09–3.84, p = 0.026 and HR: 1.19, 95% CI: 1.25–4.97, p = 0.009, respectively). The present study showed that AHNAK2 acts as a novel prognostic biomarker in patients with RC for BCa.

Objective: Nectin and nectin-like molecules (Necls) are molecules that are involved in cell–cell adhesion and other vital cellular processes. This study aimed to determine the expression and prognostic value of nectin and Necls in low grade glioma (LGG).Materials and Methods: Differentially expressed nectin and Necls in LGG samples and the relationship of nectin family and Necls expression with prognosis, clinicopathological parameters, and survival were explored using The Cancer Genome Atlas (TCGA), the Chinese Glioma Genome Atlas (CGGA), and Repository of Molecular Brain Neoplasia Data (REMBRANDT) databases. Univariate and multivariate Cox analysis models were performed to construct the prognosis-related gene signature. Kaplan-Meier curves and time-dependent receiver operating characteristic (ROC) curves and multivariate Cox regression analysis, were utilized to evaluate the prognostic capacity of the four-gene signature. Gene ontology (GO)enrichment analysis and Gene Set Enrichment Analyses (GSEA) were performed to further understand the underlying molecular mechanisms. The Tumor Immune Estimation Resource (TIMER) was used to explore the relationship between the four-gene signature and tumor immune infiltration.Results: Several nectin and Necls were differentially expressed in LGG. Kaplan–Meier survival analyses and Univariate Cox regression showed patients with high expression of NECTIN2 and PVR and low expression of CADM2 and NECTIN1 had worse prognosis among TCGA, CGGA, and REMBRANDT database. Then, a novel four-gene signature was built for LGG prognosis prediction. ROC curves, KM survival analyses, and multivariate COX regression indicated the new signature was an independent prognostic indicator for overall survival. Finally, GSEA and GO enrichment analyses revealed that immune-related pathways participate in the molecular mechanisms. The risk score had a strong negative correlation with tumor purity and data of TIMER showed different immune cell proportions (macrophage and myeloid dendritic cell) between high- and low-risk groups. Additionally, signature scores were positively related to multiple immune-related biomarkers (IL 2, IL8 and IFNγ).Conclusion: Our results offer an extensive analysis of nectin and Necls levels and a four-gene model for prognostic prediction in LGG, providing insights for further investigation of CADM2, NECTIN1/2, and PVR as potential clinical and immune targets in LGG.

Background: Acute high altitude (HA) exposure results in blood pressure (BP) variations in most subjects. Previous studies have demonstrated that higher BP is potentially correlated with acute mountain sickness (AMS). The BP load may be of clinical significance regarding systemic circulation status.Objectives: This study aimed to examine HA-induced BP changes in patients with AMS compared to those in healthy subjects. Further, we provided clinical information about the relationship between variations in 24-h ambulatory parameters (BP level, BP variability, and BP load) and AMS.Methods: Sixty-nine subjects were enrolled and all participants ascended Litang (4,100 m above sea level). They were monitored using a 24-h ambulatory blood pressure device and underwent echocardiography within 24 h of altitude exposure. The 2018 Lake Louise questionnaire was used to evaluate AMS.Results: The AMS group comprised more women than men [15 (65.2%) vs. 13 (28.3%), P &lt; 0.001] and fewer smokers [4 (17.4%) vs. 23 (50.0%), P = 0.009]. The AMS group exhibited significant increases in 24-h BP compared to the non-AMS group (24-h SBP variation: 10.52 ± 6.48 vs. 6.03 ± 9.27 mmHg, P = 0.041; 24-h DBP variation: 8.70 ± 4.57 vs. 5.03 ± 4.98 mmHg, P = 0.004). The variation of mean 24-h cBPL (cumulative BP load) (mean 24-h cSBPL: 10.58 ± 10.99 vs. 4.02 ± 10.58, P = 0.016; 24-h mean cDBPL: 6.03 ± 5.87 vs. 2.89 ± 4.99, P = 0.034) was also obviously higher in AMS subjects than in non-AMS subjects after HA exposure. 24-h mean cSBPL variation (OR = 1.07, P = 0.024) and 24-h mean cDBPL variation (OR = 1.14, P = 0.034) were independent risk factors of AMS. Moreover, variation of 24-h mean cSBPL showed a good correlation with AMS score (R = 0.504, P &lt; 0.001).Conclusions: Our study demonstrated that patients with AMS had higher BP and BP load changes after altitude exposure than healthy subjects. Excessive BP load variations were associated with AMS. Thus, BP load could be an effective indicator regarding systemic circulation status of AMS.

Abstract Background: Previous studies have proved that the aberrant expressions of PFDNs (Prefoldin) family proteins were correlated with several human cancer. However, the specific functions of PFDNs in liver hepatocellular carcinoma(LIHC) remain unknown. The study aimed to identify the prognostic biomarkers and independent indicators among PFDN1/2/3/4/5/6 in liver hepatocellular carcinoma.Methods: We used these databases including Oncomine, Ualcan, GEPIA2, Human Protein Atlas, The Cancer Genome Atlas, Kaplan-Meier plotter, cBioPortal, STRI-NG and TIMER and the software of Cytoscape in our study.Results: PFDN1/2/3/4/5/6 were highly expressed in LIHC tissues. The mRNA expression levels of PFDN1/2/3/4/5/6 were relevant to tumor grades.PFDN1/3/4/5 expressions significantly changed in different cancer stages. The protein expression levels of PFDNs were higher in LIHC tissue than normal liver tissue. Moreover, High mRNA expressions of PFDN1/2/3/4 were associated with shorter OS of LIHC patients. In multivariate analysis,high expressions of PFDN1/2/4 were independently correlated with poorer OS of LIHC patients. In our findings,55% of patients with LIHC had genetic mutations on PFDNs. Besides, there were significant associations between the expressions of PFDN1/2/3/4/5 and six types of infiltrated immune cells(B cells, CD4+T cells, CD8+T cells, neutrophil, macrophage, and dendritic cells).Conclusions:PFDN1/2/3/4 were potential prognostic markers to suggest poor OS of LIHC patients. In addition, high PFDN1/2/4 expressions were independent prognostic factors in OS for LIHC patients.

Abstract Background PLK3, a gene played an important role in cell cycle progression and stress response, was identified in different carcinomas. However, the PLK3 expression, molecular characteristics, and prognostic value in glioma still remained unknown. Methods Total 2265 glioma samples from the CGGA RNA-seq, TCGA RNA-seq, CGGA microarray, GSE16011, as well as their clinical information and genomic profiles were selected in our research. Survival analysis based on Kaplan–Meier and Cox proportional hazard model methods was performed to evaluate the prognostic value. Results Expression of PLK3 was compared in different WHO grade, isocitrate dehydrogenase (IDH) status, and molecular subtype of gliomas. We found that increased level of PLK3 was associated with malignancy and invasiveness of glioma, and high expression of PLK3 may represent malignant entities with amplification of driver oncogenes and deletion of suppressor genes. Moreover, PLK3 played a crucial role in inflammatory and immune response, and was involved in suppressive T cell anti-tumor functions. Furthermore, PLK3 was synergistic with other checkpoint members in glioma. Finally, high expression of PLK3 was associated with malignant process and reduced survival in patients with glioma. Conclusion PLK3 may serve as an indicator of poor prognosis in glioma and a potential target for immunotherapy of glioma. These results demonstrated that PLK3 may serve as a biomarker and a potential target of glioma.

ObjectiveAntiphospholipid (aPL) antibodies may activate platelets and contribute to vegetation growth and embolisation in infective endocarditis (IE). We aimed to determine the value of aPL as predictors of embolic events (EE) in IE.MethodsWe studied 186 patients with definite IE (Duke-Li criteria, all types of IE) from the Nanc-IE prospective registry (2007–2012) who all had a frozen blood sample and at least one imaging procedure to detect asymptomatic or confirm symptomatic EE. Anticardiolipin (aCL) and anti-β2-glycoprotein I (β2GPI) antibodies (IgG and IgM) were assessed after the end of patients’ inclusion. The relationship between antibodies and the detection of EE after IE diagnosis were studied with Kaplan-Meier and Cox multivariate analyses.ResultsAt least one EE was detected in 118 (63%) patients (52 cerebral, 95 other locations) after IE diagnosis in 80 (time interval between IE and EE diagnosis: 5.9±11.3 days). At least one aPL antibody was found in 31 patients (17%).Detection of EE over time after IE diagnosis was more frequent among patients with anti-β2GPI IgM (log-rank P=0.0036) and that of cerebral embolisms, among patients with aCL IgM and anti-β2GPI IgM (log-rank P=0.002 and P<0.0001, respectively).Factors predictive of EE were anti-β2GPI IgM (HR=3.45 (1.47–8.08), P=0.0045), creatinine (2.74 (1.55–4.84), P=0.0005) and vegetation size (2.41 (1.41–4.12), P=0.0014). Those of cerebral embolism were aCL IgM (2.84 (1.22–6.62), P=0.016) and anti-β2GPI IgM (4.77 (1.79–12.74), P=0.0018).ConclusionThe presence of aCL and anti-β2GPI IgM was associated with EE, particularly cerebral ones, and could contribute to assess the embolic risk of IE.
