AB  - Resistance to chemotherapeutic agents represents a major issue in anticancer therapy.
Anaplastic thyroid carcinoma (ATC) has a poor prognosis due to its aggressive behavior and
resistance to treatment. Alterations in the PI3K/AKT/mTOR pathway and/or high expression
of ATP binding cassette transporters, such as P-glycoprotein and breast cancer resistance
protein (BCRP), are frequently linked to chemo-resistance. Autophagy is a key player in the
metabolic and therapeutic stress response and represents a potential target for anticancer
therapy. Autophagy induction in response to chemotherapeutics may contribute to both
drug efficacy as well as drug resistance. We assessed the therapeutic efficacy of dual mTOR
kinase inhibitor vistusertib (AZD2014) and paclitaxel (PTX) in combination in ATC cells. Rhocell line was generated from parental human thyroid carcinoma 8505C via the selection of cells with a low accumulation of rhodamine 123 (P-glycoprotein and BCRP substrate). Rhocells were 10-fold more resistant to PTX compared to 8505C cells and more tumorigenic. Both vistusertib and PTX induced autophagosome formation in the investigated cell lines. In combination, vistusertib sensitized Rho- cells to PTX via autophagy induction and proliferation inhibition, indicating a synergistic effect between the two compounds. Additionally, vistusertib and PTX combination in Rho- and 8505C cells inhibited cell migration
and invasion in vitro. Furthermore, vistusertib and PTX combination effectively suppressed
tumor growth of ATC xenografts in immunodeficient NSG mice in vivo. Considering chemoresistance and high invasive properties of ATC, described combined approach could be useful for the design of novel targeted treatment strategies in this malignancy

AB  - Purpose: Anaplastic thyroid carcinoma (ATC) is an aggressive, chemo-resistant malignancy. Chemo-resistance is often associated with changes in activity of the RAS/MAPK/ERK and PI3K/AKT/mTOR pathways and/or a high expression of ATP binding cassette (ABC) transporters, such as P-glycoprotein (P-gp) and breast cancer resistance protein (BCRP). To assess the therapeutic efficacy in ATC of a combination of the dual mTOR kinase inhibitor vistusertib (AZD2014) and paclitaxel (PTX), we generated a new cell line (Rho-) via the selection of human thyroid carcinoma 8505C cells that exhibit a low accumulation of rhodamine 123, which serves as a P-gp and BCRP substrate.
Methods: Immunohistochemistry was used for P-gp and BCRP expression analyses in primary ATC patient samples. Spheroid formation and immunodeficient NSG mice were used for performing in vitro and in vivo tumorigenicity assays, respectively. MTT, flow-cytometry, fluorescent microscopy, cell death and proliferation assays, as well as migration, invasion and gelatin degradation assays, were used to assess the potential of AZD2014 to enhance the effects of PTX. ATC xenografts in SCID mice were used for evaluating in vivo treatment efficacies.
Results: Rho- cells were found to be 10-fold more resistant to PTX than 8505C cells and, in addition, to be more tumorigenic. We also found that AZD2014 sensitized Rho- cells to PTX by inhibiting proliferation and by inducing autophagy. The combined use of AZD2014 and PTX efficiently inhibited in vitro ATC cell migration and invasion. Subsequent in vivo xenograft studies indicated that the AZD2014 and PTX combination effectively suppressed ATC tumor growth.
Conclusions: Our data support results from recent phase I clinical trials using combinations of AZD2014 and PTX for the treatment of solid tumors. Such combinations may also be employed for the design of novel targeted ATC treatment strategies.
