DJ-1, a novel mitogen-dependent oncogene, has an important role in the progression of human malignancies, whereas tumor suppressor phosphatase and tensin homolog (PTEN) is known to control a variety of processes associated with cell survival, proliferation and invasion. DJ-1 overexpression was
Although tumor resistance remains a significant impediment to successful radiotherapy, associated regulatory markers and detailed molecular mechanisms underlying this phenomenon are not well defined. In this study, we identified inositol polyphosphate 4-phosphatase type II (INPP4B) as a novel marker
CDC25 phosphatases, significant positive regulators of the cell cycle play a pivotal role in controlling cell proliferation during development and tumorigenesis. The prevalence and clinical implications of CDC25 immunoreactivity in laryngeal squamous cell cancer (LSCC) patients however, have not
In search of factors governing the accumulation of tumor infiltrating lymphocytes (TIL), frozen sections from fresh surgical specimens of laryngeal carcinoma (n = 36) were tested by alkaline phosphatase-anti-alkaline phosphatase (APAAP) immunohistochemistry for monomorphic determinants of HLA class
The authors presented the results of study of lymphocytic and adrenal cortical function in preoperative radiotherapy of 38 laryngeal cancer patients in different oxygen regimens: in the air and under the conditions of hyperbaric oxygenation (HBO). A method of mean dose fractionation (a single focal
OBJECTIVE
To screen the differently expressed genes between laryngeal tumor and the normal tissue adjacant to the tumor and construct the subtractive cDNA library.
METHODS
The subtractive cDNA library was contructed with the suppression subtractive hybridization (SSH) technique. Nine random clones
Inositol polyphosphate 4-phosphatase type II (INPP4B) was recently identified as a tumor resistance factor in laryngeal cancer cells. Herein, we show that INPP4B-mediated resistance is associated with increased glycolytic phenotype. INPP4B expression was induced by hypoxia and irradiation.
The overall survival rate and prognosis of patients with laryngeal cancer are not optimistic despite advances in therapeutic techniques. Gene expression prognostic models enable the development of more appropriate treatment strategies. The human gene PTPN11 encoding a non-receptor protein tyrosine
The occurrence, distribution, morphology and enzymatic activity of lysosomes in malignant keratinocytes of laryngeal carcinoma was studied by electron microscopy and ultrastructural cytochemistry. Lysosomes can be observed in various forms: dense bodies, multivesicular bodies, myelin bodies and
The aim of the research was to evaluate the expression levels of cyclin E/A and CDC25A/B during laryngeal carcinogenesis. The expression was demonstrated using immunohistochemistry in 46 cases of laryngeal cancer (LSCC), 23 epithelial dysplasias (ED) and 21 samples of normal mucosa (NM). The mean
The aim of this study was to establish the prognostic value of the epidermal growth factor receptor (EGFR) and phosphatase and tensin homolog deleted on chromosome 10 (PTEN) expression on local control in patients with early stage supraglottic laryngeal squamous cell carcinoma (LSCC) Fas-associated phosphatase-1 is encoded by the protein tyrosine phosphatase, non-receptor type 13 (PTPN13) gene and attributes to the resistance to Fas-mediated apoptosis in several tumors, including squamous cell carcinoma of the head and neck (SCCHN). However, no epidemiological studies have
Laryngeal carcinoma is one of the most common malignant tumors in otorhinolaryngology. Moreover, experimental investigation showed that cancerous inhibitor of protein phosphatase 2A (CIP2A) expressed highly in various cancers. Therefore, we investigated whether CIP2A can regulate the proliferation,
OBJECTIVE
PTEN (phosphatase and tensin homologue deleted on chromosome 10), also referred to as MMAC1 (mutated in multiple advanced cancers) gene was recently identified as a putative tumor suppressor in a variety of malignant tumors. PTEN expression has been investigated in some squamous cell
