Objective: This study aimed to explore the role of IGF2BP2 in esophageal squamous cell carcinoma (ESCC) progression.

Materials And Methods: The Cancer Genome Atlas (TCGA) dataset, transcriptome sequencing, and the Gene Expression Omnibus (GEO) dataset were used to detect the expression of m6A-associated genes in ESCC. The in vitro and in vivo assays were used to explore the role of IGF2BP2 in ESCC.

Ionic liquid-enhanced silica aerogels for the specific extraction and detection of aflatoxin B1 coupled with a smartphone-based colorimetric biosensor.

The polymer ionic liquid (1-allyl-3-butylimidazolium bromide) enhanced silica aerogel was modified onto the surface of stainless-steel mesh to immobilize aptamer-1 for the specific recognition of AFB1. The porous channels of silica aerogel could prevent the interference of macromolecules in food samples. Enzyme kinetic analysis showed that the MoS/Au was an effective peroxidase mimic with a relatively low Michaelis constant (K) value of 0.

KLF5 and p53 comprise an incoherent feed-forward loop directing cell-fate decisions following stress.

In response to stress, cells make a critical decision to arrest or undergo apoptosis, mediated in large part by the tumor suppressor p53. Yet the mechanisms of these cell fate decisions remain largely unknown, particularly in normal cells. Here, we define an incoherent feed-forward loop in non-transformed human squamous epithelial cells involving p53 and the zinc-finger transcription factor KLF5 that dictates responses to differing levels of cellular stress from UV irradiation or oxidative stress.

Integration of Metallic Nanomaterials and Recognition Elements for the Specifically Monitoring of Pesticides in Electrochemical Sensing.

Although all countries have been controlling the excessive use of pesticides, incidents of pesticide residues still existed. Electrochemical biosensors are extensively applied detection techniques to monitor pesticides with the help of different types of biorecognition components mainly including, antibodies, aptamers, enzymes (i.e.

Downregulation of fibulin-4 inhibits autophagy and promotes the sensitivity of esophageal squamous cell carcinoma cells to apatinib by activating the Akt-mTOR signaling pathway.

Background: Fibulin-4, namely, EFEMP2, is an essential matricellular protein associated with a variety of malignancies. The aim of this study was to explore the role of fibulin-4 in the progression of esophageal squamous cell carcinoma (ESCC), as well as its effect on ESCC sensitivity to apatinib treatment.

Methods: The expression of fibulin-4 in ESCC tissues and cell lines was detected.

[Corrigendum] STMN1, a prognostic predictor of esophageal squamous cell carcinoma, is a marker of the activation of the PI3K pathway.

Following the publication of the above article, an interested reader drew to the authors' attention that Fig. 10A, showing the migration and invasion capabilities of Eca109 and EC9706 cells transfected with STMN1 or normal control shRNA, contained three panels with apparently overlapping data, such that the images were likely to have been derived from the same original source. The authors examined their original data and realized that errors had been made in the compilation of the panels shown in this Figure.

RUNX3 inhibits the invasion and migration of esophageal squamous cell carcinoma by reversing the epithelial‑mesenchymal transition through TGF‑β/Smad signaling.

Runt‑related transcription factor 3 (RUNX3) is a candidate tumor suppressor, and its inactivation may play a crucial role in the carcinogenesis process of numerous cancer types, including esophageal squamous cell carcinoma (ESCC). We previously revealed that RUNX3 inactivation was correlated with lymph node metastasis (LNM) and ESCC recurrence. However, the exact mechanisms of this process are still under investigation.

KLF4 activates NFκB signaling and esophageal epithelial inflammation via the Rho-related GTP-binding protein RHOF.

Understanding the regulatory mechanisms within esophageal epithelia is essential to gain insight into the pathogenesis of esophageal diseases, which are among the leading causes of morbidity and mortality throughout the world. The zinc-finger transcription factor Krüppel-like factor (KLF4) is implicated in a large number of cellular processes, such as proliferation, differentiation, and inflammation in esophageal epithelia. In murine esophageal epithelia, Klf4 overexpression causes chronic inflammation which is mediated by activation of NFκB signaling downstream of KLF4, and this esophageal inflammation produces epithelial hyperplasia and subsequent esophageal squamous cell cancer.

CEP55 promotes the proliferation, migration and invasion of esophageal squamous cell carcinoma via the PI3K/Akt pathway.

Background: Centrosomal protein 55 (CEP55) is an important prognostic biomarker that plays an essential role in the proliferation, migration and invasion of multiple tumors. We aimed to investigate the prognostic value of CEP55 in pN0 esophageal squamous cell carcinoma (ESCC) and explore its biological function in ESCC cells.

Methods: We used immunohistochemistry and Western blot analysis to detect the expression of CEP55 in ESCC.

FOXM1: A potential indicator to predict lymphatic metastatic recurrence in stage IIA esophageal squamous cell carcinoma.

Background: Previous studies have elucidated that FOXM1 may predict poor prognosis in patients with multiple solid malignant tumors. In this study we explored the differential expression of FOXM1 in stage IIA esophageal squamous cell carcinoma (ESCC) and investigated its prognostic value.

Methods: Immunohistochemistry (IHC) and Western blot were used to detect FOXM1 expression in ESCC.

STMN1, a prognostic predictor of esophageal squamous cell carcinoma, is a marker of the activation of the PI3K pathway.

The esophageal squamous cell carcinoma (ESCC) subtype with STMN1 overexpression has a high likelihood of lymphatic metastatic recurrence. However, the underlying mechanism remains to be further elucidated. We assessed the expression level of STMN1 and PTEN in 96 pN0 ESCC patient tissues using immunohistochemistry and western blot analysis.

Overexpression of IFITM3 predicts poor prognosis in stage IIA esophageal squamous cell carcinoma after Ivor Lewis esophagectomy.

Background: Recent research has shown that IFITM3 plays an important role in the tumorigenesis of many malignancies. We investigated the clinicopathological variables and prognostic value of IFITM3 in stage IIA esophageal squamous cell carcinoma (ESCC) patients.

Methods: Immunohistochemistry and Western blot analysis were used to examine IFITM3 expression in tumor specimens.

CEP55 overexpression predicts poor prognosis in patients with locally advanced esophageal squamous cell carcinoma.

Development of esophageal squamous cell carcinoma (ESCC) involves alterations in multiple genes with corresponding proteins. Recent studies have demonstrated that centrosomal protein 55 (CEP55) shares certain features with oncogenes, and CEP55 overexpression is associated with the development and progression of malignant tumors. The present study aimed to analyze, for the first time, whether CEP55 expression is related to clinicopothalogic features in the esophageal squamous cell carcinoma (ESCC), as well as patient survival.

Prognostic significance of centrosomal protein 55 in stage I pulmonary adenocarcinoma after radical resection.

Background: Pulmonary adenocarcinoma is a predominant pathologic non-small cell lung cancer (NSCLC) with a high morbidity in China. Even at histological stage I, many patients still experience recurrence after radical surgery; therefore, it is critical to determine useful indicators to stratify patients according to recurrent risk. Centrosomal protein 55 (CEP55) shares certain characteristics with oncogenes and aberrant expression of CEP55 can lead to tumorigenesis.

Overexpression of IFITM3 predicts the high risk of lymphatic metastatic recurrence in pN0 esophageal squamous cell carcinoma after Ivor-Lewis esophagectomy.

Background. Recent studies have shown that the aberrant expression of IFITM3 is implicated in the lymph node metastasis of many malignancies. Our research aimed to investigate the expression of IFITM3 in pathological N0 (pN0) esophageal squamous cell carcinoma (ESCC) and its relationship with lymph node metastatic recurrence.
