Elevated expression and activity of the epidermal growth factor receptor (EGFR) is associated with development and progression of head and neck cancer (HNC) and a poor prognosis. Clinical trials with EGFR tyrosine kinase inhibitors (e.g., erlotinib) have been disappointing in HNC. To investigate the mechanisms mediating resistance to these agents, we developed an HNC cell line (HN5-ER) with acq...

A number of studies have shown that tamoxifen increases the sensitivity of several types of solid tumours to cisplatin without increasing the associated side effects. The cellular mechanisms responsible for this increased sensitivity are currently unknown. In this study we have investigated whether tamoxifen alone or in combination with cisplatin could induce apoptosis in head and neck squamous...
The reaction of cerium(IV) ammonium nitrate (CAN) with a range of N-(p-anisyl)azoles in acetonitrile or methanol solvents leads to N-dearylation releasing the parent NH-azole and p-benzoquinone in comparable yields. The scope and limitations of the reaction are explored. It was successful with 1-(p-anisyl)pyrazoles, 2-(p-anisyl)-1,2,3-triazoles, 2-(p-anisyl)-2H-tetrazoles, and 1-(p-anisyl)penta...
زمینه و هدف: رده سلولی سرطانی بدخیم سر و گردن (HN-5)، مدل پیش‌کلینیکال مناسبی برای اهداف درمانی جدید برای این نوع سرطان محسوب می‌شود. برخلاف سایر سرطان‌ها، رده‌های سلولی متنوعی از حالت‌های اولیه و متاستازی HN5 در دسترس است. هدف از انجام این مطالعه بررسی اثر ضدسرطانی نانواکسیدروی بر میزان بقای رده سلولی سرطانی HN5 بود. روش بررسی: در این مطالعه تجربی، رده سلولی سرطان HN5 در محیط کشت DMEM (حاوی 10...
Head and neck squamous cell carcinoma (HNSCC) is a leading cause of cancer-related deaths, with increasingly more cases arising due to high-risk human papillomavirus (HPV) infection. Cisplatin-based chemoradiotherapy is a standard-of-care for locally advanced head and neck cancer but is frequently ineffective. Research into enhancing radiation responses as a means of improving treatment outcome...
Ion channels in carcinoma and their roles in cell proliferation are drawing attention. Intracellular Ca(2+) ([Ca(2+)]i)-dependent signaling affects the fate of cancer cells. Here we investigate the role of Ca(2+)-activated K(+) channel (SK4) in head and neck squamous cell carcinoma cells (HNSCCs) of different cell lines; SNU-1076, OSC-19 and HN5. Treatment with 1 µM ionomycin induced cell death...
PURPOSE Hypoxia-inducible factor 1 (HIF-1) promotes cancer cell survival and tumor progression. The specific role played by HIF-1 and tumor-stromal interactions toward determining tumor resistance to radiation treatment remains undefined. We applied a multimodality preclinical imaging platform to mechanistically characterize tumor response to radiation, with a focus on HIF-1-dependent resistanc...
زمینه و هدف: سرطان از مهمترین عوامل مرگ ومیر در دنیا می باشد و بنابراین هرگونه مطالعه در زمینه بیولوژی سرطان از اهمیت خاصی برخوردار است. سرطان های سروگردن 5-2% سرطان های بدن را در بر می گیرند که در برخی کشورها حتی بالاتر است. القای آپوپتوز یکی از مناسب ترین درمان های سرطان است. سیکلوفسفامید، ماده آلکیله کننده ای است که باعث توقف تکثیر dna و در نتیجه توقف تکثیر و بقای سلولی می گردد. بنابراین سیک...
The epidermal growth factor receptor (EGFR) and ErbB-2 transmembrane tyrosine kinases are currently being targeted by various mechanisms in the treatment of cancer. GW2016 is a potent inhibitor of the ErbB-2 and EGFR tyrosine kinase domains with IC50 values against purified EGFR and ErbB-2 of 10.2 and 9.8 nM, respectively. This report describes the efficacy in cell growth assays of GW2016 on hu...
