Abstract
OBJECTIVE To explore the expression of the family with sequence similarity 135 member B (FAM135B) and K(lysine) acetyltransferase 5 (KAT5) in esophageal squamous cell carcinoma (ESCC) in Uygur patients. METHODS The expression of FAM135B and KAT5 in ESCC tissues and paired adjacent tissues from 40 Uygur patients were detected using Roche Benchmark XT. The correlation of FAM135B and KAT5 and their correlation with the clinicopathological characteristics of the patients were analyzed. RESULTS The positivity rates of FAM135B and KAT5 in ESCC tissues were 92.50% (37/40) and 15.00%(6/40) in these patients, respectively. The ESCC tissues showed a significantly higher rate of strong FAM135B expression than the adjacent tissues [45.00% (18/40) vs 22.50% (9/40); Χ2=4.528, P=0.033], but the rates of negative KAT5 expression was similar between ESCC and adjacent tissues [85.00% (34/40) vs 87.50% (35/40); Χ2=0.105, P=0.745]. Strong expressions of FAM135B in ESCC tissues and the paired adjacent tissues were well correlated (Kendall's coefficient = 0.707, P<0.001). In ESCC tissues, a strong expression of FAM135B showed a significant negative correlation with KAT5 expression (Kendall's coefficient=-0.946, P<0.001). Neither FAM135B nor KAT5 expression was associated with the patients' gender, age, tumor site, tumor differentiation, invasion, lymph node metastasis and clinical stage (all P>0.05). CONCLUSION A strong expression of FAM135B may be an important molecular basis for the occurrence of ESCC in Uygur patients and plays its role by negatively regulating the expression of KAT5.

Rabdocoestin B exhibits antitumor activity by inducing G2/M phase arrest and apoptosis in esophageal squamous cell carcinoma. Cancer Chemother Pharmacol 2018; 81:469-481. [PMID: 29308536 DOI: 10.1007/s00280-017-3507-2] [Citation(s) in RCA: 1] [Impact Index Per Article: 0.2] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/12/2017] [Accepted: 12/19/2017] [Indexed: 12/20/2022]
Abstract
PURPOSE Esophageal squamous cell carcinoma (ESCC) is one of the most aggressive squamous cell carcinomas and is generally resistant to chemotherapy. In the present study, the cytotoxic activity of Rabdocoestin B (Rabd-B) against ESCC and the underlying mechanisms were investigated. METHODS The inhibitory effect of Rabd-B on KYSE30 and KYSE450 was evaluated by Cell Counting Kit-8 (CCK8) and colony formation assays in vitro. The cell cycle distribution and apoptosis of cells treated with Rabd-B were determined by flow cytometry. The mechanisms underlying the effects of Rabd-B were systematically examined by Western blot. The in vivo anti-tumor ability of Rabd-B was measured in mouse xenograft models and cisplatin (DDP) was used as positive control. RESULTS Rabd-B efficiently induced G2/M phase arrest in ESCC cells by upregulating the Chk1/Chk2-Cdc25C axis to inhibit the G2→M transition facilitated by Cdc2/Cyclin B1. Furthermore, Rabd-B suppressed ATM/ATR phosphorylation, thereby inhibiting BRCA1-mediated DNA repair, which resulted in mitotic catastrophe and induced cell apoptosis. Rabd-B also decreased the activity of the Akt and NF-κB survival signaling pathways and ultimately initiated the caspase-9-dependent intrinsic apoptotic pathway in ESCC cells. The apoptosis induced by Rabd-B could be partially reversed by a caspase-9-specific inhibitor (Z-LEHD-FMK) and a pan-caspase inhibitor (Z-VAD-FMK). Moreover, Rabd-B effectively suppressed tumor growth in mouse xenografts which was comparable to that of DDP without significant injuries to the mice. CONCLUSION Taken together, these findings indicate that Rabd-B is a promising precursor compound that may be useful as a treatment for ESCC and thus warrants further investigation.

Abstract
Background Esophageal squamous cell carcinoma (ESCC) is an aggressive malignancy, with a high incidence and poor prognosis. In the past several decades, hundreds of proteins have been reported to be associated with the prognosis of ESCC, but none has been widely accepted to guide clinical care. This study aimed to identify proteins with great potential for predicting prognosis of ESCC. Methods We conducted a systematic review on immunohistochemical (IHC) prognostic markers of ESCC according to the 2009 Preferred Reporting Items for Systematic Reviews and Meta-Analyses (PRISMA) Guidelines. Literature related to IHC prognostic markers of ESCC were searched from PubMed, Embase, Web of Science, and Cochrane Library until January 30th, 2017. The risk of bias of these original studies was evaluated using the Quality in Prognosis Studies (QUIPS) tool. Results We identified 11 emerging IHC markers with reproducible results, including eight markers [epidermal growth factor receptor (EGFR), Cyclin D1, vascular endothelial growth factor (VEGF), Survivin, Podoplanin, Fascin, phosphorylated mammalian target of rapamycin (p-mTOR), and pyruvate kinase M2 (PKM2)] indicating unfavorable prognosis and 3 markers (P27, P16, and E-cadherin) indicating favorable prognosis of ESCC. Conclusion Strong evidence supports that these 11 emerging IHC markers or their combinations may be useful in predicting prognosis and aiding personalized therapy decision-making for ESCC patients.

Abstract
BACKGROUND Targeted therapy with anti-human epidermal growth factor receptor-2 (HER2) monoclonal antibody in patients with HER2 overexpressed esophagogastric adenocarcinoma (EGA) improves survival; however, the effect is transient due to the development of resistance. Some studies suggest that cMet overexpression provides cross talk for epidermal growth factor receptor (EGFR) and HER2 inhibition. We sought to characterize the expression profile of the EGFR family and cMet receptors in untreated, resected EGA. METHODS This retrospective analysis included all sequential patients with esophageal or gastroesophageal junction (GEJ) adenocarcinoma who underwent primary resection, without neoadjuvant therapy or HER2 inhibition, with adequate tissue, at the University of Florida from 2001 to 2011. Central blinded immunohistochemistry (IHC) was performed on tumor specimens with EGFR, HER2, HER3, HER4 and cMet expression scored as low (0, 1+) or high (2+, 3+). Demographic and tumor characteristics were compared using Fisher exact test. Kaplan-Meier curves and univariate analysis compared survival among different receptors. RESULTS Total 52 patients were included in the study with median age 66 years. High expression of EGFR (73%), HER2 (40%), HER3 (75%), HER4 (35%) and cMet (69%) was detected among the study group. HER3 and HER4 co-expression was found in 18 (35%) cases. Pan expression of all four EGFR family members with cMet was noted in only 17% of cases. On univariate analysis, tumor stage and depth correlated with survival, while cMet + HER3 +/- EGFR receptor co-expression trended towards a worse survival. CONCLUSIONS EGFR family and cMet are frequently co-expressed in treatment naïve resected EGA or GEJ tumors. Although our data do not significantly show receptor status as a prognostic factor, the co-expression profiles support for further investigation to improve targeting of this signal transduction axis.

[PMID: 26647768 PMCID: PMC4732845 DOI: 10.3892/mmr.2015.4659] [Citation(s) in RCA: 12] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/12/2014] [Accepted: 08/20/2015] [Indexed: 11/05/2022] Open
Abstract
The present study aimed to measure the effect of heterophyllin B (HB) on the adhesion and invasion of ECA-109 human esophageal carcinoma cells, and examine the possible mechanism involved. A Cell Counting kit 8 assay was performed to determine the cell viability. Cell adhesion and invasion were determined following treatment of the ECA-109 cells with HB (0, 10, 25 and 50 µM) for 24 h. The levels of phosphorylated (p-)ATK and p-phosphoinositide 3-kinase (PI3K), and the protein levels of β-catenin were measured using western blot analysis. The mRNA and protein expression levels of E-cadherin, vimentin, snail, matrix metalloproteinase (MMP)2 and MMP9 were detected using reverse transcription-quantitative polymerase chain reaction and western blot analyses, respectively. HB (10, 25 and 50 µM) significantly suppressed the adhesion and invasion of the ECA-109 human esophageal carcinoma cells in a dose-dependant manner. The expression levels of p-ATK, p-PI3K and β-catenin were markedly decreased. The expression of E-cadherin was promoted, whereas the expression levels of snail, vimentin, MMP 2 and MMP 9 were decreased significantly in the ECA-109 cells treated with HB. In addition, HB inhibited the adhesion and invasion induced by PI3K activating peptide in the ECA-109 cells, and the protein expression levels were also adjusted. These results suggested that HB effectively suppressed the adhesion and invasion of the human esophageal carcinoma cells by mediating the PI3K/AKT/β-catenin pathways and regulating the expression levels of adhesion- and invasion-associated genes.
