BACKGROUD: 5-Aminolevulinic acid (ALA) mediated photodynamic therapy (PDT) for the treatment of esophageal cancer was more and more popularly used since it was approved for the treatment of advanced esophageal cancer in 1996. It has been reported to influence the tumor growth and metastasis via a variety of signaling pathways, but its mechanism remains to be further studied. This research studied the effects of ALA-PDT on esophageal carcinoma in vitro and in vivo, discovering its molecular regulating mechanism and the way to enhence the PDT effect...

Cancer from the gastrointestinal tract and its associated excretory organs will occur in over 300,000 Americans in 2017, with colorectal cancer responsible for over forty percent of that burden; there will be over 150,000 deaths from this group of cancers in the same time period. Disparities among subgroups related to these cancers' incidence and mortality exist. The epidemiology and risk factors associated with each cancer bear out differences for racial groups in the United States. Esophageal adenocarcinoma is more frequent in Non-Hispanic Whites, whereas esophageal squamous cell carcinoma with risk factors of tobacco and alcohol is more frequent among Blacks...

Esophageal squamous cell carcinoma (ESCC) is a highly malignant tumor associated with a poor prognosis, and the molecular mechanisms underlying its formation and progression remain poorly understood. KIAA1522 is upregulated in various tumor tissues, but its function is unknown. Alterations in KIAA1522 expression and its implication in ESCC are currently unclear. In this study, an immunohistochemical analysis of ESCC tissues showed that KIAA1522 was highly expressed in 46% (157/342) of ESCC specimens and that its expression was inversely correlated with the degree of differentiation (P=0...

Lysine-specific demethylase 1 (LSD1) is a nuclear histone demethylase and a member of the amine oxidase (AO) family. LSD1 is a flavin-containing AO that specifically catalyzes the demethylation of mono- and di-methylated histone H3 lysine 4 through an FAD-dependent oxidative reaction. LSD1 is inappropriately upregulated in lung, liver, brain and esophageal cancers, where it promotes cancer initiation, progression, and metastasis. However, unlike other lysine-specific demethylases, the role and specific targets of LSD1 in oral squamous cell carcinoma (OSCC) pathogenesis remain unknown...

NF-E2-related factor 2 (NRF2) is a master transcriptional regulator that integrates cellular stress responses and is negatively regulated by Kelch-like ECH-associated protein 1 (KEAP1) at the post-translational level. In human cancers, aberrantly stabilized NRF2, by the mutation of either NRF2 or KEAP1 or by the potential inhibition of autophagy, plays a vital role in tumor growth and chemoresistance through the activation of target genes. MicroRNAs (miRNAs) are endogenous small noncoding RNAs that can negatively regulate gene expression by interfering with translation and/or stability of target transcripts...

BACKGROUND: The prognostic value of Ki-67 expression in small cell carcinoma of the esophagus (SCCE) has not been explored in any previous studies. Therefore, we conducted this retrospective study to investigate the prognostic role of Ki-67 in SCCE for the first time. RESULTS: A total of 44 patients were included for analysis. The baseline clinicopathological data of these SCCE patients shared similar characteristics with previous studies. Ten patients were at stage I, 17 at stage II, and the remaining 17 were at stage III...

BACKGROUND: Enhancer of zeste homolog 2 (EZH2), a stemness factor, plays roles in regulation of cell differentiation and embryonic development as well as cancer progression. Deregulation of EZH2 in cancers is correlated with tumor cell invasiveness, metastasis, and the patients' poor outcome. However, the mechanistic role of EZH2 in cancer is ambiguous. In this study, we aimed to inhibit the expression of EZH2 in a cancer cell line, and evaluate consequence changes in gene expression pattern...

Esophageal squamous cell carcinoma (ESCC) has a high morbidity in China, accounting for 90% of all esophageal carcinoma cases. Hence, identifying drug targets for prevention and treatment of ESCC is essential. Due to its critical role in the regulation of cell apoptosis, Mcl-1 holds great potential as a target for treatment against ESCC. In current study, we used a 4-nitroquinoline-1-oxide (4-NQO)-induced ESCC mouse model of test whether A-1210477, a Mcl-1 small molecular inhibitor, could repress ESCC development...

Analysis of our microRNA (miRNA) expression signatures of human cancers based on RNA sequencing have shown that both strands of pre-miR-150, miR-150-5p (the guide strand) and miR-150-3p (the passenger strand), are significantly reduced in cancer tissues. We have investigated the functional significance of both strands of pre-miR-150 in cancer cells. The aim of this study was to investigate the antitumor function of these miRNAs and how these miRNAs regulated oncogenic targets in esophageal squamous cell carcinoma (ESCC)...

Esophageal squamous cell carcinoma (ESCC) is one of the most common malignancies in the world, marked by dysphagia and weight loss, bringing great suffering to patients. HNF1A‑AS1 (HAS1), a long non-coding RNA (lncRNA), has been identified prevalently involved in various human cancers. However, the exact effects and molecular mechanisms of HAS1 in ESCC progression are still elusive. In this study, upregulated expression of HAS1 was detected in ESCC tissues and four human ESCC cell lines (KYSE70, KYSE450, EC109 and EC970) compared with normal tissues and cell lines...

Sirtuin 6, a member of sirtuin family, is generally regarded as a tumor suppressor as it participates in suppressing hypoxia-inducible factor 1α and MYC transcription activity by deacetylating H3K9 (histone H3 lysine 9) and H3K56 (histone H3 lysine) at promoters of target genes, leading to the aerobic glycolysis inhibition and cell growth suppression. However, its expression has recently been reported to be highly elevated in a series of tumors, including prostate cancer, breast cancer, and non-small cell lung cancer, indicating that sirtuin 6 plays dual roles in tumorigenicity in a cell/tumor type-specific manner...

Long non-coding RNAs are classified as a kind of RNA, which are longer than 200 nucleotides in length and cannot be translated into proteins. Multiple studies have demonstrated that long non-coding RNAs are involved in various cellular processes, including proliferation, differentiation, cell death, and metastasis. Among numerous long non-coding RNAs, we focus on Sprouty4-Intron 1 (SPRY4-IT1), a well-known long non-coding RNA that is overexpressed in various kinds of tumor tissues and cell lines. Accumulating evidences show that SPRY4-IT1 was dysregulated in various cancers, including melanoma, breast cancer, esophageal squamous cell carcinoma, non-small cell lung cancer, gastric cancer, colon cancer, and hepatocellular carcinoma, and amplification of SPRY4-IT1 was associated with different clinicopathological features of cancer patients...

BACKGROUND: Recombinant human lymphotoxin-α derivative (rhLTα-Da) is a lymphotoxin-α derivative that is missing 27 N-terminal amino acid residues. Previous studies indicated a benefit from the addition of rhLTα-Da to cisplatin-based treatment in patients with metastatic esophageal squamous cell carcinoma. The current study was conducted to evaluate the efficacy and safety of rhLTα-Da plus cisplatin and fluorouracil (PF) in patients with mESCC. METHODS: Patients from 15 centers in China were randomly assigned (1:1:1) to 3 arms (arm A, PF plus 10 μg/m(2) daily rhLTα-Da; arm B, PF plus 20 μg/m(2) daily rhLTα-Da; arm C, PF alone)...

A case of esophageal carcinoma exclusively composed of adenocarcinoma simulating an esophageal gland duct in a 61-year-old man is presented. The tumor arose as a slightly elevated lesion in the middle intrathoracic esophagus. It was almost completely overlaid with non-neoplastic stratified squamous epithelial cells. Beneath the overlying surface epithelium, an adenocarcinoma that was bilayered in structure diffusely invaded both the mucosal and submucosal layers. Although the tumor consisted exclusively of adenocarcinomatous cells, a keratinizing squamous cell carcinoma component was focally observed...

Recent studies have shown that some members of the tripartite motif-containing protein family function as important regulators for carcinogenesis. In this study, we investigated whether tripartite motif-containing protein 44 acts as a cancer-promoting gene through its overexpression in esophageal squamous cell carcinoma. We analyzed esophageal squamous cell carcinoma cell lines to evaluate malignant potential and also analyzed 68 primary tumors to evaluate clinical relevance of tripartite motif-containing protein 44 protein in esophageal squamous cell carcinoma patients...

The rarity of primary small cell carcinoma of the esophagus (PSCE) has limited the clinical feature and survival analysis with large sample size. Tissue chromogranin A (CgA) protein expression has been reported to be a useful biomarker for diagnosing PSCE. Interestingly, recent studies have indicated tissue CgA as a significant prognostic marker in multiple human cancers, but without PSCE. The present study, thus, was undertaken to characterize the clinicopathological changes and to evaluate the associations of tissue CgA expression with clinical response on Chinese PSCE patients...
