Ionic channel activity is involved in fundamental cellular behaviour and participates in cancerous features such as proliferation, migration and invasion which in turn contribute to the metastatic process. In this study, we investigated the expression and role of voltage-gated sodium channels in non-small-cell lung cancer cell lines. Functional voltage-gated sodium channels expression was inves...

AIM To explore the expression of phosphorylated STAT3 (pSTAT3) in non-small cell lung cancer(NSCLC) and its clinical significance. METHODS The expression of pSTAT3 was detected in 59 cases of NSCLC and their para-cancerous tissue by immunohistochemical staining. RESULTS (1) The expression of pSTAT3 in NSCLC was significantly higher than that in para-cancerous tissue. (2) The expression of p...

background and objective: in addition to the use of chemicals in food, pharmaceutical, cosmetic and hygiene industries, use of herbal and natural compounds have also increased. it seems natural ingredients compared with the chemical components show less side effects, such as mutagenicity and carcinogenesis however, their use can also be associated with side effects and toxicity. some significan...

Cisplatin, a commonly used chemotherapeutic, is associated with ototoxicity, renal toxicity and neurotoxicity, thus identifying means to increase the therapeutic index of cisplatin may allow for improved outcomes. A SNP (rs4343077) within EPS8, discovered through a genome wide association study of cisplatin-induced cytotoxicity and apoptosis in lymphoblastoid cell lines (LCLs), provided impetus...

background: mehr-80 is a newly established adherent human large cell lung cancer cell line that has not been transfected until now. this study aims to define the optimal transfection conditions and effects of some critical elements for enhancing gene delivery to this cell line by utilizing different non-viral transfection procedures. methods: in the current study, calcium phosphate (cap), deae-...

Genetic instability promotes cancer progression (by increasing the probability of cancerous mutations) as well as hinders it (by imposing a higher cell death rate for cells susceptible to cancerous mutation). With the loss of tumor suppressor gene function known to be responsible for a high percentage of breast and colorectal cancer (and a good fraction of lung cancer and other types as well), ...

PURPOSE To investigate the expression of hypoxia-inducible factor prolyl hydroxylase 3 (HIFPH3) in non-small cell lung cancer (NSCLC) and explore the correlation of HIFPH3 expression with lymph node metastasis and microvessel density (MVD). MATERIALS AND METHODS A total of 73 cases of NSCLC specimens, 24 cases of para- cancerous tissues, and 20 normal pulmonary tissues were collected for HIFP...
