Association between SFRP promoter hypermethylation and different types of cancer: A systematic review and meta-analysis.

Association between SFRP promoter hypermethylation and different types of cancer: A systematic review and meta-analysis. Oncol Lett. 2019 Oct;18(4):3481-3492 Authors: Yu J, Xie Y, Li M, Zhou F, Zhong Z, Liu Y, Wang F, Qi J Abstract Abnormal methylation of secreted frizzled-related proteins (SFRPs) has been observed in various human cancer types. The loss of SFRP gene expression induces the activation of the Wnt pathway and is a vital mechanism for tumorigenesis and development. The aim of the present systematic review was to assess the association between SFRP methylation and cancer risk. A meta-analysis was systematically conducted to assess the clinicopathological significance of SFRP methylation in cancer risk. The Cochrane Library, PubMed and Web of Science databases were comprehensively searched, and 83 publications with a total of 21,612 samples were selected for the meta-analysis. The pooled odds ratios (ORs) and corresponding 95% confidence intervals (CIs) were calculated to evaluate the degree of associations between SFRP promoter methylation and cancer risk. Subgroup analysis, meta regression and sensitivity analysis were used to identify the potential sources of heterogeneity. SFRP1, SFRP2, SFRP4 and SFRP5 hypermethylation was significantly associated with cancer risk, with ORs of 8.48 (95% CI, 6.26-11.49), 8.21 (95% CI, 6.20-10.88), 11.41 (95% CI, 6.42-20.30) and 6.34 (95% CI, 3.86-10.42), respectively. SFRP2 methylation was significantly asso...

ConclusionThe results of our series of 13 cases indicate that intraoral soft tissue metastatic carcinomas have a male predilection with a male to female ratio of 11:2, are commonly found in the gingiva and alveolar mucosa (76.9%), present frequently as an easy-bleeding pyogenic granuloma-like lesion (92.3%). In addition, the most common primary cancer site is the liver.

Conclusion Lung shunt fraction appears low among patients with non-hepatocellular carcinoma liver malignancies. Further analysis examining the necessity of pre-Y90 technetium-99 m macro aggregated albumin lung shunt fraction studies in patients with non-hepatocellular carcinoma malignancies is warranted, since a consolidated yttrium-90 radioembolization without prior lung shunt fraction evaluation could reduce resource consumption, improve workflows, and patient access.

AbstractThe reaction of cyclohexan-1,3-dione with either of malononitrile or ethyl cyanoacetate gave the 4-amino-6,7-dihydro-5H-chromen-5-one derivatives3a and3b, respectively. The reaction of the latter compounds with cyanoacetylhydrazine gave the hydrazide –hydrazone derivatives5a and5b, respectively. Compounds5a,b were used as the key starting materials for the synthesis of thiophen, coumarin, and pyridine derivatives. The newly synthesized compounds were evaluated against three human cancer cell lines, including HCT116 (colon carcinoma cell), MGC803 (gastric carcinoma cell), and Huh7 (hepatoma carcinoma cell). Th...

Authors: Fujita J, Sakurai T Abstract Gankyrin (also called PSMD10, p28, or p28GANK) is a crucial oncoprotein that is upregulated in various cancers and assumed to play pivotal roles in the initiation and progression of tumors. Although the in vitro function of gankyrin is relatively well characterized, its role in vivo remains to be elucidated. We have investigated the function of gankyrin in vivo by producing mice with liver parenchymal cell-specific gankyrin ablation (Alb-Cre;gankyrinf/f) and gankyrin deletion both in liver parenchymal and in non-parenchymal cells (Mx1-Cre;gankyrinf/f). Gankyrin defici...

Authors: Ouyang H, Zhang L, Xie Z, Ma S Abstract Long noncoding RNAs (lncRNAs) have been shown to participate in the development and progression of a number of different types of cancer, including hepatocellular carcinoma (HCC). A recent report has indicated that lncRNA MAFG-antisense 1 (AS1) promotes colorectal cancer. However, the role of MAFG-AS1 in other types of cancer remains unclear. The aim of the present study was to examine the effect of lncRNA MAFG-AS1 in HCC. Based on The Cancer Genome Atlas database and reverse transcription-quantitative PCR results, it was determined that lncRNA MAFG-AS1 expression wa...

We reported a case of a 66-year-old man after surgery, chemotherapy, and radiation therapy for colon cancer. Two months after these therapies, the patient complained of nonproductive cough for 1 week. Diagnoses: 18F-fluorodeoxyglucose (FDG)-positron emission tomography (PET)/computed tomography (CT) scanning revealed increased FDG uptake along the thickened bronchovascular bundles, in bilaterally scattered ground-glass opacities and in mediastinal lymphadenopathy. The transbronchial biopsy and pathological study confirmed the diagnosis of PLC. Interventions: Antineoplastic treatment (cetuximab) were administered afte...

Background: Long non-coding RNA colon cancer-associated transcript 2 (CCAT2) is a 1752-bp lncRNA transcribed from m8q24 genomic region. A lot of investigations have confirmed the involvement of CCAT2 in the tumorigenesis of many cancer types. Previous studies found that over-expression of CCAT2 significantly promoted cell migration and proliferation, and inhibited apoptosis of HCC cells. In the present investigation, the clinical value and prognostic significance of CCAT2 were investigated. Methods: The 122 pairs of HCC tissues and adjacent normal liver tissues were acquired between September 2013 and February 2018. T...
