STC1 sensitized CaSki cells to drugs.

Abstract

<p>(A) Effect of cisplatin on CaSki cells growth. CaSki cells were treated with with or without cisplatin (0, 1, 2, and 3 mg/L) for 96 h, removing aliquots every 24 h to evaluate cell viability. (B) Effect of thapsigargin on CaSki cells growth. CaSki cells were treated with with or without thapsigargin (0, 1, 3, 6, and 9 µM) for 72 h, removing aliquots every 24 h to evaluate cell viability. (C) Effect of rapamycin on CaSki cells growth. CaSki cells were treated with with or without rapamycin (0, 0.01, 0.1, 0.5, and 1 mg/L) for 72 h, removing aliquots every 24 h to evaluate cell viability. (D) STC1 sensitized CaSki cells to cisplatin. CaSki/STC1 or CaSki/NC cells were treated with cisplatin (2 mg/L) for 96 h. MTT assays detected the cell growth of CaSki/STC1 or CaSki/NC cells in the face of cisplatin (*<i>p</i><0.05). (E) STC1 sensitized CaSki cells to thapsigargin. CaSki/STC1 or CaSki/NC cells were treated with thapsigargin (3 µM) for 72 h. MTT assays detected the cell growth of CaSki/STC1 or CaSki/NC cells in the face of thapsigargin (*<i>p</i><0.05). (F) STC1 sensitized CaSki cells to rapamycin. CaSki/STC1 or CaSki/NC cells were treated with rapamycin (0.5 mg/L) for 72 h. MTT assays detected the cell growth of CaSki/STC1 or CaSki/NC cells in the face of rapamycin (*<i>p</i><0.05). Data was expressed as mean ± SEM of three separated experiments. A value of P<0.05 was considered as statistical significance.</p
