Figure Lengend Snippet: Figure 2. (A) The representative immunohistochemical staining of ASPM negative, weak, moderate, and strong cases. (B) In our cohort, high ASPM expression predicted better LUAD prognosis (Log-rank test p = 5.4e-4). (C) In patients who received chemotherapy, high ASPM expression was related to better overall survival (Log-rank test p = 5.0e-4). (D) In patients who did not received chemotherapy, ASPM expression was not related to patient overall survival (Log-rank test p = 0.48). (E) Multivariate regression analysis showed ASPM was not an independent prognostic factor while other protective factor included chemother apy and risk factor included clinical stages. (F) time dependent ROC analysis was conducted at time points 365, 1095, and 1825 days. The AUC and confidence intervals were evaluated using the ci function of pROC.
Article Snippet: Immunohistochemistry and special staining the Luad tissues (n = 160) were obtained from surgically resected specimens and made into tissue microarray. the sections were de-paraffinized and hydrated, and the endogenous peroxidase was blocked. antigen retrieval was performed using the dako target Retrieval Solution, High pH (dako ominis, agilent technologies, Santa Clara, Ca, uSa), in a ptLink set at 98 °C for 25 min. the tissue sections were incubated with an anti-aSpm rabbit polyclonal antibody (1:200, a02584-1, Boster, China) 1h at 37 °C. detection of immunostaining was achieved by an enzyme-conjugated polymer complex (K8002, dako, denmark) adapted for autostainers from daKo (dako autostainer, agilent technologies). the staining intensity in selected areas was scored as follows: 0, no staining; 1, weak staining; 2, moderate staining; 3, strong staining. the stained area was scored as follows: 0, no staining; 1, 1–10% positive cells; 2, 10–50% positive cells; 3, > 50% positive cells. the final score was evaluated by multiplying the staining intensity and stained area percentage. the negative and weak staining cases were considered as low expression group while the moderate and strong staining cases were defined as high expression group in later analysis.
