Oral squamous cell carcinoma (OSCC) accounts for >80% of head and neck malignancies. p21, p27 and survivin proteins are abnormally expressed in OSCC and have been previously reported to correlate with cell proliferation and apoptosis. However, the prognostic significance of p21, p27 and survivin remains controversial. The aim of the present study was to investigate the association of clinical p...
The association between human papillomavirus type 16 (HPV16) and oral cancer has been widely reported. However, detecting anti-HPV antibodies in patient sera to determine risk for oral squamous cell carcinoma (OSCC) has not been well studied. In the present investigation, a total of 206 OSCC serum samples from the Malaysian Oral Cancer Database & Tissue Bank System, with 134 control serum sampl...
BACKGROUND The development of oral squamous cell carcinoma (OSCC) is a multistep process that involves in both genetic alterations and epigenetic modifications. DJ-1, a negative regulator of tumor suppressor PTEN, functions as an oncogene in many types of cancers. However, its role in OSCC is poorly known. METHODS Immunohistochemical staining and Western blotting were performed to evaluate th...
Oral squamous cell carcinoma (OSCC) is the most prevalent form of oral cancer. Inducible nitric oxide synthase (iNOS) and p53 are associated with a variety of human cancers, but their expression and interaction in OSCC have not been fully explored. In this study, we investigated the expression of iNOS and p53 in OSCC and their correlation with tumor development and prognosis. In addition, we ex...
Metastatic oral squamous cell carcinoma (OSCC) is frequently associated with recurrent gene abnormalities at specific chromosomal loci. Here, we utilized array comparative genomic hybridization and genome-wide screening of metastatic and non-metastatic tongue tumors to investigate genes potentially contributing to OSCC progression to metastasis. We identified predominant amplifications of chrom...
BACKGROUND Overexpression of Oct4, an important transcription factor of embryonic stem cells (ESC), has been reported in several cancers. The aim of this study was to determine the emerging role of Oct4 in oral squamous cell carcinoma (OSCC) both in vitro and in vivo. METHODOLOGY/PRINCIPAL FINDING Tumourigenic activity and molecular mechanisms of Oct4 overexpression or knockdown by lentiviral...
مقدمه: اسکواموس سل کارسینومای دهانی (OSCC) شایعترین سرطان دهان میباشد و دندانپزشکان نقشی حیاتی در پیشگیری و تشخیص زودهنگام آن دارند. هدف از مطالعه حاضر مقایسه آگاهی دانشجویان دندانپزشکی و دندانپزشکان عمومی شهر همدان در ارتباط با OSCC بود. مواد و روشها: این مطالعه توصیفی- مقطعی در همدان و در سال 1388 انجام شد. 80 دندانپزشک عمومی و 70 دانشجوی دندانپزشکی در این مطالعه شرکت نموده و به پرسشنامه ...
UNLABELLED Epidemiological data from oral squamous cell carcinoma (OSCC) is mostly derived from North American, European and East Asian populations. OBJECTIVE The aim of this study was to report the demographic and clinicopathological features from OSCC diagnosed in an Oral Pathology service in southeastern Brazil in an 8-year period. MATERIAL AND METHODS All OSCC diagnosed from 2005 to 201...
BACKGROUND As a regulator essential for many cell cycle-related proteins, the robust expression of Cell cycle-Related and Expression-elevated Protein in Tumor (CREPT) implicates a poor diagnosis of endoderm and mesoderm-derived tumors. Whether CREPT plays the same role in the tumorigenesis derived from ectodermal tissues remains elusive. METHODS To explore the role of CREPT in ectoderm-derive...
INTRODUCTION The presence of a variety of MDM2 splice variants has been reported in a range of different tumor types and is associated with poor patient prognosis. Furthermore, several MDM2 variants have been shown to have oncogenic properties. Despite this, MDM2 splice variants have not been comprehensively characterized in oral squamous cell carcinoma (OSCC). MATERIALS AND METHODS MDM2 spli...
