It has become apparent that hypoxia and hypoxia-inducible factor-1 (HIF-1) activation have the potential of modulating the activity of major epithelial-mesenchymal transition (EMT)-triggering pathways by regulating the expression and activity levels of major transcriptional repressors. The aim of our study was to elucidate the role of HIF-1α and HIF-2α, and(More)
It has been admitted that urokinase-type plasminogen activator receptor (u-PAR) is overexpressed in many human malignant tumors including oral squamous cell carcinoma (OSCC) and plays an important role in a variety of cancer key cellular events as a versatile signaling orchestrator. In our study, a retroviral vector expressing u-PAR-specific siRNA was(More)
OBJECTIVES Our objectives were to analyze the clinical features of maxillofacial space infection (MSI) patients admitted to the West China Hospital of Stomatology over a five-year period, and to identify potential risk factors associated with life-threatening complications. METHODS A retrospective medical chart review was performed and the(More)
Chemokines and chemokine receptors have critical roles in cancer metastasis and have emerged as one of the targeting options in cancer therapy. However, the treatment efficacy on both tumor and host compartments needs to be carefully evaluated. Here we report that targeting CXCR3 decreased tumor cell migration and at the same time improved host anti-tumor(More)
AIM The aim of this study is to explore the relationship between the neutrophil-to-lymphocyte ratio (NLR) and clinicopathological features in patients with papillary thyroid carcinoma (PTC). METHODS We performed an analysis of 843 patients, including 321 patients with PTC, 83 patients with thyroid adenoma and 439 patients with nodular goiter (NG).(More)
To investigate the mechanism of cartilage degradation induced by overloading in the temporomandibular joint (TMJ), the effect of cyclic mechanical compressive stress on the activity of plasminogen activator (PA) and the expression of the predominant components of the PA system were analyzed in cultured mandibular condylar chondrocytes (MCCs) in rats. MCCs(More)
The overexpression of c-kit seems to be frequent and specific in salivary adenoid cystic carcinoma (ACC), however, there is little information on correlation between c-kit expression and the invasion and metastasis. Recently, the data showed that Slug, a transcription factor of epithelial-mesenchymal transitions (EMT), is a molecular target that contributes(More)
Nonsyndromic oral cleft is a common developmental malformation of humans. Embryonic development is regulated by microRNAs. MicroRNA-140-5p (miR-140-5p) was found to regulate palatal development. As sequence variants in miRNA genes are likely to affect miRNA expression and/or maturation, we investigated the miRNA-140 gene and identified a SNP (rs7205289:(More)
OBJECTIVE Transcription factor Snail1 has a central role in induction of epithelial-mesenchymal transition (EMT). The aim of the present study was to study the association of Snail1 expression with clinicopathologic factors and prognosis in adenoid cystic carcinoma (ACC) of salivary gland. STUDY DESIGN Demographic variables and primary tumor site, dates(More)
BACKGROUND It has been reported that zinc-finger transcription factor Slug plays a critical role in tumor proliferation and differentiation, relapse, invasion, metastasis, and decreased survival. However, there is little information on the expression and role of Slug in salivary adenoid cystic carcinoma (ACC). METHOD Demographic variables and primary(More)
