CONTEXT The influence of the novel heat shock protein 90 (hsp90) inhibitor NVP-AUY922 (AUY922) on anaplastic thyroid carcinoma (ATC) cells has not been investigated. OBJECTIVE The effect of AUY922 alone or in combination with the histone deacetylase inhibitor PXD101 on survival of ATC cells was evaluated. RESULTS In ATC cells, AUY922, compared with(More)
Apigenin promotes apoptosis in cancer cells. We studied the effect of apigenin on cell survival and c-Myc expression in FRO anaplastic thyroid carcinoma (ATC) cells. Apigenin caused apoptosis via the elevation of c-Myc levels in conjunction with the phosphorylation of p38 and p53. In the c-Myc siRNA-transfected and apigenin-treated cells, compared with the(More)
In this study, we evaluated the effect of the hsp70 inhibitor VER155008 on survival of anaplastic thyroid carcinoma (ATC) cells. In ATC cells, VER155008 increased the percentages of dead cells and vacuolated cells. VER155008 did not lead to the cleavage of caspase-3 protein regardless of pretreatment with z-VAD-fmk. VER155008 increased LC3-II protein levels(More)
The effec.t of BIIB021, a novel heat shock protein 90 (hsp90) inhibitor, on survival of thyroid carcinoma cells has not been evaluated. In this study, the impact of BIIB021 alone or in combination with the histone acetyltransferase inhibitor triptolide on survival of thyroid carcinoma cells was identified. In 8505C and TPC-1 thyroid carcinoma cells, BIIB021(More)
The influence of the heat shock protein 90 (hsp90) inhibitor SNX5422 alone or in combination with the histone deacetylase (HDAC) inhibitors PXD101, suberoylanilide hydroxamic acid (SAHA), and trichostatin A (TSA) on survival of anaplastic thyroid carcinoma (ATC) cells was investigated. In 8505C and CAL62 cells, SNX5422 caused cell death with concomitant(More)
BACKGROUND/AIM The aim of the present study was to elucidate whether tunicamycin (TM) induces paraptosis as a cell death subroutine in anaplastic thyroid carcinoma (ATC) cells. MATERIALS AND METHODS 8505C, CAL62 and FRO cells were used. After treatment of TM, cell survival and morphology were investigated. The effect of the BRAF(V600E) inhibitor PLX4032(More)
We aimed to elucidate the effect of herbimycin A (HMA), a heat shock protein 90 inhibitor, on cell growth and epithelial-mesenchymal transition (EMT) in anaplastic thyroid carcinoma (ATC) cells. HMA inhibited cell growth and migration concomitantly with increase of E-cadherin as well as decrease of N-cadherin and vimentin. Moreover, HMA upregulated p21 and(More)
In this study, the combined effect of doxorubicin with cucurbitacin B on survival of anaplastic thyroid carcinoma cells was evaluated. For experiments, 8505C and CAL62 human anaplastic thyroid carcinoma cells were used. Cell viability, the percentage of viable cells, and cytotoxic activity were measured using(More)
BACKGROUND We studied the effect of apigenin in combination with tumor necrosis factor (TNF)-related apoptosis-inducing ligand (TRAIL) on cell survival and the influence of AKT inhibition on the combined effect of apigenin with TRAIL in anaplastic thyroid carcinoma (ATC) cells. MATERIALS AND METHODS The human 8505C and CAL62 ATC cell lines were used. (More)
AIM The aim of the present study was to evaluate the effect of heat-shock protein 90 (HSP90) inhibitors, 17-allylamino-17-demethoxygeldanamycin (17-AAG) and herbimycin A (HMA) on survival of anaplastic thyroid carcinoma (ATC) cells. MATERIALS AND METHODS Antitumor activities of 17-AAG and HMA were investigated in FRO ATC cells. RESULTS In FRO ATC cells,(More)
