Figure Lengend Snippet: Representative images of STMN1 immunostaining in adjacent normal tissues ( a,b ) and different stages of GBC tissues (GBC tissue of Grade II ( c,d ); GBC tissue of Grade II~III, III ( e,f )). Twelve pairs of GBC and pericarcinomatous tissues were sectioned and subjected to immunohistochemistry, as described in Methods section (Origianl magnification is 200×). Red arrows indicated STMN1 positive signal. The expression levels of STMN1 between GBC and adjacent tissue were shown in the scatter plot ( p = 0.0003, significance was determined using Student’s t -test) ( g ). The STMN1 expression level was scored by semi-quantitative scoring system as described in Methods section. The protein level of STMN1 was detected in two GBC cell lines (GBC-SD, and SGC-996) ( h ), with GBC and pericarcinomatous tissue were used as positive and negative controls, respectively. GAPDH was used as a control for protein loading. NT: adjacent normal tissues; T: tumor tissue. GBC: Gallbladder carcinoma.

Conclusive diagram shows the relationship between the expression of STMN1and chemoresponse In the ovarian cancer tissues examined. The high STMAN expression is significantly correlated with chemoresistance. From 24 ovarian cancer tissues samples, 14 tissue samples showed positive STMN1 expression. Of them, 11 samples (78.5%) were chemoresistant while 3 samples (21.5%) were chemoresponsive. On the other hand, ten samples showed negative or very week STMN1 expression. C. Western blotting analysis of STMN1 expression in four cell lines. Chemoresistant KF-TX cells express more STMN1 compared with parental KF cells. The blot shows that STMN1 expression is associated with IC50 to TX. SKOV-3, lowest IC50, shows the lowest expression level of STMN1.

Figure Lengend Snippet: A. Acetylated α-tubulin in the far immunoblot of α-tubulin immunoprecipitant from cell lysates isolated from either control/GFP or two stable clones overexpressing miR-31(#1 and #2). Acetylated tubulin is greater in KF-TX cells which overexpress miR-31, with depleted STMN1, compared with control transfectant which show higher STMN1. B. Immunocytochemical staining shows tubulin in KF-TX cells overexpressing miR-31 and their control (GFP). Representative images of a miR-31 clone (#1) and a control clone (#1) were fixed and stained with antibodies against α-tubulin. miR-31 overexpressing cells show more polymerized and bundled tubulin nearby the margins of the cells compared with normal tubulin distribution in the control as an evidence for STMN1 depletion in miR-31 clone compared with control one. miR-31 overexpression slows interphase in KF-TX cells. C. Phase contrast image obtained from time laps microscopic study (additional files; 1, 2). The series for a cell exiting mitosis. Plot summarizes data from >10 cells and three independent experiments per condition. STMN1 depletion increased interphase duration by approximately 210 min (**, P <0.05), compared with cells progressed through mitosis with normal kinetics. D. Immunoflorcent images show the distribution of the tubulin in the representative clones (KF-TX-miR-31; clone#1 and control-GFP #1). The miR-31 overexpressing cells showed bundled tubulin nearby the margimes of the cytoplasm E. Luciferase activity after transfection of the indicated 3′-UTR-driven reporter constructs. Reporter plasmid containing 3′-UTR region of STMN1 with binding site of miR-31 or with the binding site deleted, *P< 0.05.
