In the past several years, the αv integrin subfamily has been repeatedly found to be involved in tumor progression and angiogenesis. The aim of this study was to investigate the expression of the integrin αv subfamily in laryngeal squamous cell carcinoma (LSCC), and to correlate the expression rate with tumor biological behavior and angiogenesis of the(More)
Osteopontin (OPN) is a secreted phosphoprotein, which functions as a cell attachment protein and cytokine that signals through two cell adhesion molecules, integrin αvβ3 and CD44, to regulate cancer growth and metastasis. The aim of this study was to investigate the expression of OPN and integrin αv (ITGAV, main receptor of the OPN) in laryngeal and(More)
The aim of this study was to evaluate the usefulness of osteopontin (OPN) expression level in plasma and tumor tissues of patients with laryngeal and hypopharyngeal squamous-cell carcinoma for predicting metastasis and survival of this tumor. The OPN expression in tumor tissues was detected by immunohistochemical staining in a tissue microarray of laryngeal(More)
Dysregulation of a numerous microRNAs (miRNAs) has been implicated in laryngeal squamous cell carcinoma (LSCC). Among those miRNAs, miR‑21 and miR‑221 are co‑overexpressed and commonly target the phosphatase and tensin homolog protein (PTEN) that is located in the PTEN‑Akt signaling pathway. The present study investigated whether co‑inhibition of miR‑21 and(More)
MicroRNAs (miRNAs) have been shown to be promising biomarkers in predicting cancer prognosis. However, inappropriate or poorly optimized processing and modeling of miRNA expression data can negatively affect prediction performance. Here, we propose a holistic solution for miRNA biomarker selection and prediction model building. This work introduces the use(More)
Laryngeal squamous cell carcinoma (LSCC) is a highly aggressive malignant cancer. The regulation of LSCC progression by long non-coding RNA (lncRNA) was not well understood. In this study, we reported that the lncRNA H19 was upregulated in LSCC. The expression levels of H19 were inversely correlated with the survival rate of LSCC patients. Knockdown of H19(More)
Cilengitide is a chemical synthesis cyclopeptide containing RGD sequence, which can be used as a small molecule antagonist targeted to integrin αν (ITGAV). The aim of present study was to investigate the effect on proliferation and cell apoptosis of the cilengitide in laryngeal cancer cells. In the study, we have treatmented the cultured cells of laryngeal(More)
BACKGROUND To examine the expression of cysteine-rich 61 (Cyr61/CCN1) protein in laryngeal squamous- cell carcinoma (LSCC) tissues, and its relationship with the tumor epithelial-mesenchymal transition (EMT), invasion, metastasis, and prognosis. MATERIALS AND METHODS Immunohistochemistry was used to detect the expressions of Cyr61, Vimentin (Vim), and(More)
