BACKGROUND: A disintegrin and metalloprotease with thrombospondin motif (ADAMTS) enzymes play important roles in cell functions including adhesion, invasion, migration, and proliferation. ADAMTS-6 is a member of the ADAMTS family; reports of its relationship with esophageal squamous cell carcinoma (ESCC) progression are rare. It is unclear whether ADAMTS-6 could be an independent ESCC biomarker. METHODS: ADAMTS-6 expression was detected by immunohistochemistry (IHC) in 171 paraffin-embedded ESCC specimens; relationships with patients' clinicopathological features and Twist-1 expression were analyzed by the Pearson Chi-square method, respectively...

Fontan-associated liver disease is a hepatic disorder arising from hemodynamic changes and systemic venous congestion following Fontan surgery. The histological changes produced in the liver are similar but not equivalent to those seen in other forms of cardiac liver disease. While the natural history of this form of liver disease is not well established, over time many Fontan patients develop portal hypertension-related complications such as ascites, variceal hemorrhage or encephalopathy. Fontan survivors also show an increased risk of hepatocellular carcinoma...

Socioeconomic status (SES) is suspected to influence the risk of esophageal squamous-cell carcinoma (ESCC) in China, however, the evidence is still inconclusive and the selection of SES indicators remains inconsistent. In current study, we examined the association between SES and risk of ESCC based on a population-based case-control study in Taixing, China, with 1298 histopathology-confirmed cases and 1900 controls recruited between October 2010 and September 2013. Data on SES indicators was collected using a structured questionnaire...

Based on their overexpression and important roles in progression and therapy-resistance in malignant diseases, the inhibitor of apoptosis protein family (IAP) members, survivin and X-linked inhibitor of apoptosis protein (XIAP), represent attractive candidates for targeted therapy. The present study investigated the prognostic and biological relevance of survivin and XIAP in esophageal squamous-cell carcinoma (ESCC) and esophageal adenocarcinoma (EAC). Survivin and XIAP expression was analyzed by immunohistochemistry using tissue microarrays containing 120 ESCC and 90 EAC samples as well as the corresponding non-neoplastic esophageal mucosa samples...

Hepatocholangiocarcinoma (cHCC-ICC) is a rare primary hepatic tumor defined by the presence of histological features of both hepatocellular carcinoma (HCC) and intrahepatic cholangiocarcinoma (ICC). Its prevalence ranges from 1%-5% of all primary liver cancers. We report the case of a 55-year-old cirrhotic male patient admitted to our university hospital for dysphagia, revealing a 10 cm lower-third esophageal metastasis of an unresectable cHCC-ICC with stem-cell features. Computed tomography and abdominal magnetic resonance imaging scans revealed multiple hepatic lesions combining features of both HCC and ICC, associated with synchronous bone metastasis...

Esophageal squamous cell carcinoma (ESCC) is one of the most common cancers worldwide; however, clinical and pathological parameters have limited ability in discriminating between clinically significant and indolent ESCC. Since RasGRP3 transcript levels have prognostic value in discriminating ESCC with different clinical aggressiveness, we decided to investigate its putative oncogenic role in ESCC. We found that RasGRP3 was highly expressed in ESCC cells. Suppression of endogenous RasGRP3 expression in esophageal cell lines reduced Ras-GTP formation as well as AKT phosphorylation...

BACKGROUND & AIMS: Guidelines recommend endoscopic surveillance of patients with Barrett's esophagus (BE) to identify those with dysplasia (a precursor of carcinoma) or early-stage esophageal adenocarcinoma (EAC), who can be treated endoscopically. However, it is unclear whether surveillance increases survival times of patients with BE. We performed a systematic review and meta-analysis to qualitatively and quantitatively examine evidence for the association of endoscopic surveillance in patients with BE with survival and other outcomes...

14-3-3ζ is overexpressed in several cancers, including esophageal squamous cell carcinoma (ESCC), and plays an important role in tumorigenesis. However, the mechanisms underlying its tumorigenesis remain unclear. Here we report that 14-3-3ζ was upregulated in ESCC tumors, compared with adjacent normal tissues; 14-3-3ζ levels were positively correlated with ESCC lymph node metastasis and recurrence. Overexpression of 14-3-3ζ promoted the tumor growth and invasion of ESCC in vitro and in vivo, whereas depletion of 14-3-3ζ suppressed these effects...

Esophageal cancer is one of the most common types of cancer, which is a leading cause of cancer-related death worldwide. Based on histological behavior, it is mainly of two types (i) Esophageal squamous cell carcinoma (ESCC), and (ii) esophageal adenocarcinoma (EAD or EAC). In astronomically immense majority of malignancies, receptor tyrosine kinases (RTKs) have been kenned to play a consequential role in cellular proliferation, migration, and metastasis of the cells. The post-translational modifications (PTMs) including phosphorylation of tyrosine (pY) residue of the tyrosine kinase (TK) domain have been exploited for treatment in different malignancies...

BACKGROUND & AIMS: Long non-coding RNAs (lncRNAs) are expressed in tissue-specific pattern, but it is not clear how these are regulated. We aimed to identify squamous cell carcinoma (SCC)-specific lncRNAs and investigate mechanisms that control their expression and function. METHODS: We studied expression patterns and functions of 4 SCC-specific lncRNAs. We obtained 113 esophageal SCC (ESCC) and matched non-tumor esophageal tissues from a hospital in Shantou City, China, and performed quantitative reverse transcription PCR assays to measure expression levels of LINC01503...

Genome wide association studies (GWAS) have identified a series of genetic variants associated with the risk of esophageal adenocarcinoma (EAC)/Barrett's esophagus (BE), which was different from those loci for esophageal squamous cell carcinoma (ESCC). It is important to evaluate whether these susceptibility loci for EAC/BE are also implicated in ESCC development. In the current study, we analyzed genetic variants at 3p13, 9q22, 16q24 and 19p13 in a case-control study including 2139 ESCC patients and 2463 cancer-free controls in a Chinese population, and further characterized the biological relevance of genetic variants by functional assays...

BACKGROUND: miR-34a has been shown to be involved in P53 regulation. In this study, we aimed to evaluate the expression level of miR-34a in esophageal cancer and compare it with that of the normal marginal tissues. METHODS: Tumor and marginal tissues were obtained from 50 patients with esophageal cancer. After RNA extraction, expression level of miR-34a was determined using SYBR green master mix and real-time quantitative PCR. RESULTS: It was observed that there was a downregulation of miR-34a in tumoral tissue of esophageal patients in comparison to normal marginal tissues...

Alterations in mitochondrial DNA (mtDNA) copy numbers in various human cancers have been studied, but any such changes in esophageal squamous cell carcinoma (ESCC) are not established. In the present study, we investigated the correlation of mtDNA copy number with clinicopathologic features, prognosis, and malignant potential of ESCC. MtDNA copy numbers of resected specimens from 80 patients treated with radical esophagectomy were measured by quantitative real-time PCR analyses. Human ESCC cells, TE8 and TE11, were cultured, and depletion of mtDNA content was induced by knockdown of mitochondrial transcription factor A expression or treatment with ethidium bromide...
