Article Title: Expression of Stress-Induced Phosphoprotein1 (STIP1) is Associated with Tumor Progression and Poor Prognosis in Epithelial Ovarian Cancer
doi: 10.1002/gcc.22136
Figure Lengend Snippet: STIP1 is highly expressed in human ovarian cancer cells and tissue specimens. A. STIP1 protein levels were analyzed by western blot. GAPDH was included as an internal loading control. B. Representative immunohistochemical staining for STIP1 in formalin-fixed paraffin-embedded EOC tissues (400×). C. IHC staining score of STIP1 in EOC samples was significantly higher than that in healthy controls, benign ovarian tumors, or borderline ovarian tumors (P < 0.001, P < 0.001, and P = 0.039 respectively). Differences between tumor stages and grades were statistically significant, with advanced-stage and poor-grade specimens having higher immunoreactivity.
Article Snippet: The membranes were blocked with 5% skim milk in TBST (50 mM Tris, 150 mM NaCl, 0.05% Tween-20, pH 7.5) for 1 h at room temperature, followed by incubation with anti-STIP1 rabbit polyclonal antibody (mouse monoclonal, Cat.# sc-32761, Santa Cruz Biotechnology, Santa Cruz, CA), anti-Smad5 (Cell Signaling, Danver, MA), anti-phosphoSmad1/5(Ser463/465) (Cell Signaling), anti-human β-actin (Cell Signaling), or anti-GAPDH (Santa Cruz Biotechnology) overnight at 4°C.
