Kee Siang Lim, Kosaku Mimura, Ley-Fang Kua, Kensuke Shiraishi, Koji Kono
Esophageal squamous cell carcinoma (ESCC) is an aggressive upper gastrointestinal cancer and effective treatments are limited. Previous studies reported that natural killer (NK) cells expanded by coculturing with K562-mb15-41BBL feeder cells, a genetically modified K562 leukemia cell line that expresses membrane-bound interleukin (IL)-15 and 41BBL ligand, were highly proliferative and highly cytotoxic. Here, we investigated the potential of expanded NK cells for ESCC treatment. We analyzed both genetic and surface expression levels of NKG2D ligands (NKG2DLs) in ESCC using publicly available microarray data sets and ESCC cell lines...

Esophageal squamous cell carcinoma (ESCC) is the eighth cause of cancer-related deaths worldwide. To screen potential biomarkers associated with early recurrence/metastasis (R/M) of ESCC patients after radical resection, ESCC patients were analyzed by a comparative proteomics analysis using iTRAQ with RPLC-MS to screen differential proteins among R/M groups and adjacent normal tissues. The proteins were identified by qRT-PCR, Western blotting, and tissue microarray. The protein and mRNA expression difference of PHB2 between tumor tissues of ESCC patients and adjacent normal tissues, ESCC patients with and without metastasis, four ESCC cell lines and normal esophageal epithelial cells were inspected using immunohistochemical staining, qRT-PCR, and Western blotting...

Esophageal squamous cell carcinoma (ESCC) presents poor prognosis, and patients diagnosed with this tumor currently lack target treatments. Therefore, in order to identify potential targets for ESCC treatment, we carried out a transcriptome analysis with ESCC and paired nonmalignant surrounding mucosa samples, followed by a master regulator analysis, and further explored the role of the identified central regulatory genes through in vivo and in vitro assays. Among the transcription factors deregulated/enriched in ESCC, we focused on FOXM1 because of its involvement in the regulation of critical biological processes...

Esophageal adenocarcinoma (EAC) is one of the deadliest carcinoma faced by gastroenterologists. Any insult to esophagus that causes replacement of normal squamous epithelium with columnar intestinal epithelium is labelled as the initiating event of the metaplasia-neoplasia sequence. Barrett's esophagus is the precursor to EAC. Currently, endoscopically obtained biopsies are used to detect neoplastic changes in patients with Barrett's esophagus (BE); however, it is not cost effective and hence a better screening modality is needed...

Esophageal squamous cell carcinoma (ESCC), the main subtype of esophageal cancer, is the eighth most common cancer worldwide. Cell adhesion molecule 2 (CADM2) has been reported to be a tumor suppressor and is usually downregulated in several cancers. However, the role of CADM2 in ESCC remains unknown. The aim of the present study was to evaluate the potential role and underlying action mechanism of CADM2 in ESCC. Herein, we found that CADM2 was low-expressed in ESCC tissues and cell lines. CADM2 overexpression inhibited proliferation and induced apoptosis of ESCC cells...

Esophageal squamous cell carcinoma (ESCC) is the most common form of esophageal cancer in China. Since chemotherapy is the standard clinical intervention for advanced ESCC, the development of highly effective and minimal/non-toxic drugs is essential to improve the clinical outcome and prognosis of the patients. A novel derivative of vanillin, 6-bromine-5-hydroxy-4-methoxybenzaldehyde (BVAN08), has been recently reported to activate different cell death pathways in cancer cells. In this study, we demonstrate that BVAN08 exhibits a potent anti-proliferation effect on ESCC cells (TE-1 and ECA-109) by inhibiting the expression of PLK1, an important mitotic kinase...

Esophageal squamous cell carcinoma (ESCC) is amongst the most aggressive human malignancies, representing a significant health burden worldwide. Autophagy is an evolutionarily conserved catabolic process that degrades and recycles damaged organelles and misfolded proteins to maintain cellular homeostasis. Alterations in autophagy are associated with cancer pathogenesis, including ESCC; however, the functional role of autophagy in ESCC remains elusive. Here, we discuss the clinical relevance of autophagy effectors in ESCC and review current knowledge regarding the molecular mechanisms through which autophagy contributes to ESCC...

BACKGROUND: The Keap1-Nrf2 pathway is a key antioxidant and redox signaling cascade. Pathway abnormalities enhance the reactive oxygen species scavenging ability of cancer cells; thus the pathway is involved in carcinogenesis and resistance to chemoradiotherapy (CRT). This retrospective study was conducted to examine the status of the Keap1-Nrf2 pathway in locally advanced esophageal squamous cell carcinoma (ESCC) and to analyze its prognostic value in patients receiving CRT. METHODS: Nrf2 and Keap1 expression were immunohistochemically examined in 152 ESCC and 31 normal esophageal mucosae...

We review the significance of cancer-stromal interactions (CSIs) in the development, morphogenesis and progression of human gastric and esophageal cancer based on the data obtained from co-culture experiments. Orthotopic fibroblasts in the gastric cancer stroma not only promoted their growth by cancer cells but were also responsible for the mobility, morphogenesis and epithelial-to-mesenchymal transition (EMT) of the cancer cells through CSI. Bone marrow-derived mesenchymal stem cells could be part of the origin of cancer-associated fibroblasts (CAFs) of the gastric cancer providing an advantageous microenvironment for the restoration of cancer stem cells with the induction of the EMT...

Since the early 1970s, the incidence of esophageal adenocarcinoma (EA) has increased dramatically in most Western populations while the incidence of esophageal squamous cell carcinoma has decreased. As a result, EA has become the predominant subtype of esophageal cancer in North America and Europe and is an important contributor to overall cancer mortality. Barrett's esophagus (BE), a metaplastic columnar epithelium of the distal esophagus, is the known precursor lesion for EA. EA and BE occur more frequently in white men over 50 years old, as well as in people with frequent symptoms of gastroesophageal reflux, in smokers, and in people who are obese...

The incidence of gastric cardia cancer (GCC) is high in China. However, the clinicopathological characteristics and the carcinogenesis of GCC are unclear. Toll-like receptor 4 (TLR4) is an important innate immunity receptor and has a role in non-GCC (NGCC). We compared the clinicopathological characteristics of GCC patients from a high-risk area in China to esophageal cancer (EC) patients. Immunohistochemistry for TLR4 was performed in 201 histological samples of normal gastric cardia mucosa ( n = 11), gastric cardia inflammation ( n = 87), and GCC ( n = 103)...

The latest 8th edition of TNM Classification of Malignant Tumours by Union for International Cancer Control (UICC) and 11th edition of Japanese Classification of Esophageal Cancer by Japan Esophageal Society (JES) are the two major classifications widely accepted as tools for clinical staging of esophageal cancer. Both systems consist of three main categories, i.e., T, N, and M, but large difference exists between the two. JES system has more detailed sub-classification of T1 tumors reflecting meticulous work by Japanese investigators on superficial esophageal cancer...

Esophageal carcinoma is aggressive in nature and its prognosis is largely dependent on the degree of invasion. Histone deacetylase 6 (HDAC6), as the most unique member of HDACs family, has the positive activity to promote initiation and progression of various cancers via targeting multiple non-histone proteins in cytoplasm. In this study, we found that HDAC6 was over-expressed in three esophageal cancer cell lines (KYSE140, KYSE170, KYSE180) when compared to non-carcinoma esophageal epithelial cell HEEC-1. Then two HDAC6 specific siRNAs and HDAC6 inhibitor tubastatin A greatly suppressed KYSE140 and KYSE180 cells proliferation and migration, and the inhibition of cell motility was accompanied by elevated acetylation of α-tubulin, a target of HDAC6...

Esophageal cancer is one of the common causes of cancer mortality in the world. The predominant histological subtype, esophageal squamous cell carcinoma (ESCC), often results in poor prognosis due to the lack of effective approaches for the early diagnosis and treatment, highlighting the need for preventive intervention against this disease. Here we report that dietary tocopherols significantly prevents esophageal carcinogenesis by inhibiting the activation of NF-κB and the subsequent interaction of chemokine CXCL9/10/11 with their receptor CXCR3 in ESCC induced by N-nitrosomethylbenzylamine (NMBA) in murine models...
