Tumor metabolism is a crucial factor for the carcinogenesis of oral squamous cell carcinoma (OSCC). Expression of IGF-R1, glycolysis-related proteins (GLUT-1, HK 2, PFK-1, LDHA, TKTL1), mitochondrial enzymes (SDHA, SDHB, ATP synthase) were analyzed in normal oral mucosa (n = 5), oral precursor lesions (simple hyperplasia, n = 11; squamous intraepithelial(More)
PURPOSE There are no reliable laboratory procedures to monitor intraoperative tumor antigen dispersal in patients with squamous cell carcinoma of the head and neck. This study evaluated the use of serologic parameters as perioperative indicators of systemic manifestations. PATIENTS AND METHODS In 28 patients, serial measurements of different tumor markers(More)
Biomarkers allowing the characterization of malignancy and therapy response of oral squamous cell carcinomas (OSCC) or other types of carcinomas are still outstanding. The biochemical suicide molecule endonuclease DNaseX (DNaseI-like 1) has been used to identify the Apo10 protein epitope that marks tumor cells with abnormal apoptosis and proliferation. The(More)
OBJECTIVE Tumor hypoxia is a crucial negative prognostic factor associated with outcome of oral squamous cell carcinoma (OSCC). STUDY DESIGN Expression of glucose transporter 1 (GLUT-1) (solute carrier family 2 [facilitated glucose transporter], member 1 [SLC2A1]) was analyzed in OSCC specimen (n = 161) and cancer cell lines by immunohistochemistry and(More)
A weak Ca(2+)-binding site (Ka = 0.8 x 10(3) M-1, at pH 7) was identified in the mature part of levansucrase. An amino acid substitution (Thr-236-->Ile) in this site alters simultaneously the affinity for calcium, the folding transition and the efficiency of the secretion process of levansucrase. Moreover, the ability of the Bacillus subtilis cell wall to(More)
Glutaminolysis is a crucial factor for tumor metabolism in the carcinogenesis of several tumors but has not been clarified for oral squamous cell carcinoma (OSCC) yet. Expression of glutaminolysis-related solute carrier family 1, member 5 (SLC1A5)/neutral amino acid transporter (ASCT2), glutaminase (GLS), and glutamate dehydrogenase (GLDH) was analyzed in(More)
OBJECTIVES Monitoring surgical removal of oral squamous cell carcinomas (OSCC) is being routinely performed through clinical and imaging follow-up. We analyzed the potential use of serum lactate, lactate dehydrogenase (LDH), and LDH isoenzymes (LDH 1-5) as biomarkers in blood for the monitoring of surgical removal of OSCC. MATERIALS AND METHODS Serum(More)
BACKGROUND Apoptosis resistance is a crucial factor for the carcinogenesis of oral squamous cell carcinoma (OSCC). METHODS Expression of apoptosis resistance-related ATP-binding cassette (ABC) transporter ABCB5 [subfamily B (MDR/TAP) member 5] and DNaseX (Apo10) were analyzed in normal oral mucosa (n = 5), oral precursor lesions (simple hyperplasia, n =(More)
The aim of this study was to analyse the expression of 1,25-dihydroxyvitamin D3 receptor (VDR) in oral cancers are squamous cell carcinomas (OSCC) to evaluate whether oral tissue may be a new potential target for biologically active 1,25-(OH)2D3 or its analogues. Expression of VDR was analysed in OSCC specimen (n = 191) and cancer cell lines (BICR3, BICR56)(More)
For bone regeneration constructs using human jaw periosteal cells (JPC) the extent of osteoinductive ability of different three-dimensional scaffolds is not yet established. We analyzed open-cell polylactic acid (OPLA) scaffolds for their suitability as bone engineering constructs using human JPC. Cell adhesion and spreading was visualized on the surface of(More)
