BACKGROUND/AIMS Several studies have shown secreted clusterin (sCLU) silencing directed against sCLU mRNA in sCLU-rich lung cancer cell lines sensitized cells to chemotherapy. However, the molecular mechanisms underlying the effect of sCLU silencing on lung cancer cell chemosensitivity is not known. In the present study, we aimed to determine that vector(More)
BACKGROUND Our previous study has demonstrated that knockdown of activated ERK1/2(pERK1/2) sensitizes pancreatic cancer cells to chemotherapeutic drug gemcitabine (Gem) treatment. However, the details of this survival mechanism remain undefined. It has also shown that Bcl-2 confers resistance and Bax sensitizes to gemcitabine-induced apoptosis in pancreatic(More)
OBJECTIVE Anaplastic thyroid carcinoma (ATC) is one of the most aggressive human cancers and often shows resistance to multimodal therapeutic approaches. It has been shown that the transcriptional repressor Slug inhibits the chemotherapeutic agent-induced apoptosis of cancer cells. We evaluated whether targeting of Slug could augment doxorubicin(More)
Identifying prognostic factors for osteosarcoma (OS) aids in the selection of patients who require more aggressive management. XB130 is a newly characterized adaptor protein that was reported to be a prognostic factor of certain tumor types. However, the association between XB130 expression and the prognosis of OS remains unknown. In the present study, we(More)
Anaplastic thyroid cancer (ATC) is a locally aggressive type of thyroid tumor with high rate of distant metastases. It is often incurable because it does not respond to radioiodine, radiotherapy, or chemotherapy. With conventional treatment, the median survival is about 6 months; therefore, new treatment options are needed. S100A4 is a calcium-binding(More)
BACKGROUND AND AIMS Overexpression of transforming growth factor (TGF)-β1 has been implicated in promoting cell survival, migration and invasion in many cancers, including anaplastic thyroid cancer (ATC). In the present study, we studied the effect of suppressing TGF-β1 by RNA silencing on the survival, invasion and metastasis of ATC cells. METHODS Small(More)
BACKGROUND AND AIMS The cytologic patterns of lymph node fine needle aspirations (FNAs) exhibit a wide variation in different diseases and in different ethnic groups in various geographical locations. Knowledge of lymphadenopathy patterns in a given geographical region is essential for making a confident diagnosis of suspected disease in that location. In(More)
BACKGROUND Patients with papillary thyroid cancer (PTC) and enlarged cervical lymph nodes (CLNs) are usually assessed by fine-needle aspiration biopsy cytology (FNAB-C). Thyroglobulin (Tg) is frequently detected in washout of fine-needle aspirates (FNA) of these lymph nodes. The aim of this study was to evaluate the accuracy of the measurement of FNAB-Tg in(More)
OBJECTIVE Anaplastic thyroid cancer (ATC) is one of the most lethal human malignancies. However, the molecular mechanisms of ATC invasion are poorly understood. The transforming growth factor-beta (TGF-β) signaling pathway plays a critical role in promoting tumor metastasis. TGF-β1 was found to be overexpressed in anaplastic thyroid cancer (ATC). We(More)
BACKGROUND AND OBJECTIVE MicroRNAs play an important role in cell proliferation, apoptosis, differentiation, and invasion by regulating the expression of various genes. For example, the downregulation of microRNA-199a-3p (miR-199a-3p) that is noted in numerous human malignancies, including hepatocellular carcinoma (HCC), results in a poor prognosis in(More)
