A Smooth Esophageal Stricture Causing Dysphagia

We report a case of a smooth esophageal narrowing secondary to intramural metastasis from pulmonary adenocarcinoma in a patient with no previous history of neoplasia. Since standard linear echoendoscope could not overpass the malignant stricture, we obtained a histological diagnos is by fine-needle aspiration biopsy using an echobronchoscope (EBUS), due to its lower diameter. The EBUS scope represents a valuable tool to obtain cytological specimens in patients with esophageal strictures.

ConclusionsA series of studies provide detailed information to understand lncRNA AFAP1-AS1 role in various human cancers. LncRNA AFAP1-AS1 is an oncogene in tumors that have been studied so far, and it may act as a useful tumor biomarker and therapeutic target.

Abstract BACKGROUND: Dkk3 protein attenuates the expression of Wnt3a, Wnt5a and LRP6, and their interaction, and interacts with βTrCP to suppress wnt/β-catenin pathway. METHODS: We performed a bioinformatics analysis of Dkk3 mRNA expression through Oncomine, TCGA and Kaplan-Meier databases up to July 10, 2017. RESULTS: Up-regulated Dkk3 expression was higher in gastric, breast, and ovarian cancers than normal tissues (p

Abstract BACKGROUND AND AIMS: Increasing evidence has shown the critical role of long non-coding RNA cytoskeleton regulator (CYTOR) in cancers. The expression of CYTOR is reported to be up-regulated in many kinds of cancers, such as gastric cancer, hepatocellular carcinoma, colon cancer, lung adenocarcinoma, oesophageal squamous cell carcinoma and renal cell carcinoma. Here, we summarized related studies and performed a meta-analysis to investigate the prognostic value of CYTOR in multiple cancers. METHODS: Eligible studies were retrieved from PubMed, Embase and Cochrane Library databases, and the role of CYT...

Authors: Qiao B, Luo W, Liu Y, Wang J, Liu C, Liu Z, Chen S, Gu J, Qi X, Wu T Abstract Background &Aims: Quite a few studies had investigated the correlation between CXC chemokine receptor 2 (CXCR2) and cancer. This meta-analysis was aimed to comprehensively summarize the previous studies and to explore the prognostic value of CXCR2 in patients with cancer. Materials and Methods: An adequate literature search in EMBASE and PubMed was conducted. Articles in English which have reported CXCR2 expression in patients and enough data to calculate hazard ratio (HR) were included. Effect estimates were analyzed wit...

Authors: Ma Y, Chen Y, Li Y, Grün K, Berndt A, Zhou Z, Petersen I Abstract Cystatin A (CSTA), belonging to type 1 cystatin super-family, is expressed primarily in epithelial and lymphoid tissues for protecting cells from proteolysis of cytoplasmic and cytoskeletal proteins by cathepsins B, H and L. CSTA acts as a tumor suppressor in esophageal cancer, however, its role in lung cancer has not yet been elucidated. Here we found that CSTA was down-regulated in all lung cancer cell lines compared to normal lung epithelial cells. CSTA was restored in most lung cancer cell lines after treatment with demethylation ag...

Abstract Long non‐coding RNAs (lncRNAs), a group of non‐protein‐coding RNAs with more than 200 nucleotides in length, are involved in multiple biological processes, such as the proliferation, apoptosis, migration and invasion. Moreover, numerous studies have shown that lncRNAs play important roles as oncogenes or tumour suppressor genes in human cancers. In this paper, we concentrate on actin filament‐associated protein 1‐antisense RNA 1 (AFAP1‐AS1), a well‐known long non‐coding RNA that is overexpressed in various tumour tissues and cell lines, including oesophageal cancer, pancreatic ductal adenocarcinoma...

Authors: Zhuang Y, Jiang H, Li H, Dai J, Liu Y, Li Y, Miao L, Cai H, Xiao Y, Xia H, Wang Y, Shi M Abstract An increasing number of deregulated long non-coding RNAs (lncRNA) have been implicated in cancer in humans, suggesting that lncRNAs may be involved in tumorigenesis or tumor progression. In previous investigations, lncRNA, AFAP1-AS1 has been found to be associated with several cancers, including nasopharyngeal carcinoma, lung cancer and esophageal adenocarcinoma. However, the function of AFAP1-AS1 in lung cancer has not been reported. In our present study, we found that AFAP1-AS1 was overexpressed in lung aden...

Background and objective OLC1 (overexpressed in lung cancer 1), screened out and cloned in our previous research, is a new gene associated with lung cancer. It is highly expressed in lung cancer and many other malignant tumors, and is associated with poor prognosis of esophageal squamous cell carcinoma, ovarian cancer, breast cancer and colorectal cancer. The aim of this research was to detect the expression level of OLC1 in the tumor tissues of lung adenocarcinoma (ADC) and squamous cell carcinoma (SCC) and explore its relationship with the prognosis of lung cancer patients. Methods Lung cancer tissues of 108 SCC and 90 A...

Abstract Recent findings indicate that long noncoding RNAs (lncRNAs) were dysregulated in many kinds of tumors including esophageal squamous cell carcinoma (ESCC). LncRNA AFAP1‐AS1 was found to be upregulated in hepatocellular carcinoma (HCC), lung cancer, colorectal cancer, esophageal adenocarcinoma (EAC), pancreatic ductal adenocarcinoma, and nasopharyngeal carcinoma, while its clinical value and potential function in ESCC are still unknown. Expression of AFAP1‐AS1 was measured in 65 ESCC tissues and corresponding noncancerous tissues by quantitative real‐time polymerase chain reaction, which revealed that AFAP1‐...
