Figures & data
Notes: (A) The cell growth curves of Ishikawa parental- and progestin-resistant cells are shown by MTT assay. Data are expressed as the mean results from three independent experiments. ***P<0.001. (B) Western blot showed expression of PR. (C) Western blot showed expression of autophagy markers EIG121, Beclin-1, P62, LC3B, ATG3, and ATG5 and the expression of β-actin as internal control.
Abbreviations: MTT, 3-(4,5-dimethylthiazol-2yl)-2,5-diphenyltetrazolium bromide; PR, progesterone receptor; PR-A, progesterone receptor isoform A; PR-B, progesterone isoform B; OD, optical density; h, hours.

Notes: (A) Western blot assay was used to characterize the activation of PI3K/AKT/mTOR pathway. (B) Western blot showed expression of AKT1 in control and AKT1-knockdown cells. (C) The cell growth curves of control and AKT1 knockdown resistant cells are shown by MTT assay. Data are expressed as the mean numbers of independent triplicate experiments. ***P<0.001. (D) Western blot showed expression of autophagy markers LC3B, ATG3 and ATG5 and the expression of β-actin as internal control.
