Lung cancer has the highest mortality rate of any tissue-specific cancer in both men and women. Research continues to investigate novel drugs and therapies to mitigate poor treatment efficacy, but the lack of a good descriptive lung cancer animal model for preclinical drug evaluation remains an obstacle. Here we describe the development of an orthotopic lung cancer animal model which utilizes t...

Follicular thyroid cancer (FTC) is the second most common type of thyroid cancers. In order to develop more effective personalized therapies, it is necessary to thoroughly evaluate patient-derived cell lines in in vivo preclinical models before using them to test new, targeted therapies. This study evaluates the tumorigenic and metastatic potential of a panel of three human FTC cell lines (WRO,...

Background: Within the context of developing techniques to facilitate the diagnosis of the thyroid diseases, the elemental composition of pathological thyroid tissue (neoplastic and non-neoplastic) was investigated by proton induced X-ray emission. The PIXE has been widely used as a sensitive technique for trace elemental analysis in both biological and medical fields. Materials and Methods: Th...

PURPOSE B-Raf(V600E) may play a role in the progression from papillary thyroid cancer to anaplastic thyroid cancer (ATC). We tested the effects of a highly selective B-Raf(V600E) inhibitor, PLX4720, on proliferation, migration, and invasion both in human thyroid cancer cell lines (8505c(B-RafV600E) and TPC-1(RET/PTC-1 and wild-type B-Raf)) and in primary human normal thyroid (NT) follicular cel...

To investigate the clinical impact of Met/hepatocyte growth factor receptor (HGF-R) expression in thyroid cancer we studied 163 thyroid carcinomas (129 papillary, 21 follicular, and 13 anaplastic) from patients followed-up for 25-147 months postthyroidectomy. Forty-nine thyroid adenomas were also studied. Met/HGF-R expression was evaluated by semiquantitative immunohistochemistry, measuring bot...

PURPOSE There are no effective therapies for patients with poorly differentiated papillary thyroid cancer (PTC) or anaplastic thyroid cancer (ATC), and metastasis to the bone represents a significantly worse prognosis. Src family kinases (SFKs) are overexpressed and activated in numerous tumor types and have emerged as a promising therapeutic target, especially in relation to metastasis. We rec...

To evaluate the importance of trace amounts of elements in thyroid cancer etiology and diagnostics, instrumental neutron activation analysis has been used to estimate Ag, Co, Cr, Fe, Hg, I,Rb, Sb, Sc, Se, and Zn concentrations in malignant and benign thyroid nodules as well as in apparently intact paranodular thyroid tissue. Resected material from 135 patients was obtained from operations. Fort...
