UNLABELLED Detection of abnormally elevated levels of molecules in patients with oral cancer may be useful in early diagnosis. These markers can be included in current Histopathology grading and in TNM staging systems of Oral Squamous Cell Carcinoma (OSCC) to make it more efficient. Several pro-angiogenic molecules have been assessed for the same reason. Endothelin-1 (ET-1) is a vasoactive pept...
OBJECTIVES We aimed to conduct a meta-analysis of human papillomavirus (HPV) as a risk factor for oesophageal squamous cell carcinoma (OSCC) in China, using all eligible studies published in the English and Chinese language literature. DESIGN The random effect model was used to analyse the pooled OR. The I(2) and Q tests were included in the subgroup analyses. SETTING Literature searches of...
BACKGROUND Hypermethylation in promoter regions of genes might lead to altered gene functions and result in malignant cellular transformation. Thus, biomarker identification for hypermethylated genes would be very useful for early diagnosis, prognosis, and therapeutic treatment of oral squamous cell carcinoma (OSCC). The objectives of this study were to screen and validate differentially hyperm...
Background: China has one of the highest incidence rates of oesophageal cancer in the world. The role of human papillomavirus (HPV) has been extensively researched in oesophageal squamous cell carcinoma (OSCC) with indeterminate results. The majority of these studies have been conducted in the Chinese population. Evidence for a definitive HPV-OSCC association could potentially support prophylac...
مقدمه: لیکن پلان دهانی (OLP) به عنوان ضایعهای با قابلیت تبدیل شدن به کارسینوم سلول سنگفرشی دهان (OSCC) پیشنهاد گردیده است. اما پتانسیل بدخیمی این ضایعه و ارتباط آن با OSCC مورد اختلاف نظر میباشد. از آنجا که تکثیر کنترل نشده سلولی شاخص وقوع تغییر بدخیمی به شمار میرود، هدف از مطالعه حاضر مقایسه بروز سیکلین D1 در ضایعات OLP و OSCC بود. مواد و روشها: در این مطالعه توصیفی- تحلیلی با استفاده از ر...
Recent studies have shown that promoter hypermethylation of tumor suppressor genes is an important factor in carcinogenesis of several human organs. The purpose of this study was to examine the methylation status of CHFR, a novel cell cycle regulatory gene, in both primary oral cancer tumors and the adjacent normal mucosa, and to clarify the relation between the methylation status and expressio...
Zyxin is an evolutionarily conserved protein that has been implicated in the regulation of actin assembly and is mainly located at focal adhesions. However, the biological roles of Zyxin in cancer cells are incompletely understood. We analyzed the functions of Zyxin in cell migration and the invasive potential of OSCC. Zyxin expression was examined using eight OSCC cell lines with two different...
Oral cancer, predominantly oral squamous cell carcinoma (OSCC), is one of the most leading causes of cancers worldwide. Due to a low 5-year survival rate, highly effective methods for the early detection of OSCC are totally needed. MicroRNAs (miRNAs), as promising biomarkers, can bring insights into tumorigenesis of oral cancers. However, studies on the accuracy of miRNAs detection in OSCC have...
In oral squamous cell carcinoma (OSCC), metastasis to lymph nodes is associated with a 50% reduction in 5-year survival. To identify a metastatic gene set based on DNA copy number abnormalities (CNAs) of differentially expressed genes, we compared DNA and RNA of OSCC cells laser-microdissected from non-metastatic primary tumors (n = 17) with those from lymph node metastases (n = 20), using Affy...
BACKGROUND Mammalian mismatch repair system is responsible for maintaining genomic stability during repeated duplications, and human MutL homolog 1 (hMLH1) protein constitutes an important part of it. Various isolated studies have reported the altered expression of hMLH1 in oral leukoplakia (OL) and oral squamous cell carcinoma (OSCC). Research is lacking in the quantitative estimation and comp...
