TMZ inhibits tumor growth and enhances the expression of NLRP1, IL-1β, and Notch1 in 1205Lu tumors in vivo. (A) Tumor growth curve of 1205Lu parental cells injected subcutaneously in mice, intraperitoneally treated with a TMZ cycle or 10% dimethyl sulfoxide (DMSO) (Control) (indicated by arrows). Tumor growth was monitored for 26 days. Data are expressed as the mean ± SEM. n = 10 tumors (control) or 12 tumors (TMZ). (B) qRT-PCR analysis of NLRP1 expression in single tumor cells isolated from the tumor tissues studied in (A). Data are expressed as the mean ± SEM. n = 3 samples. * p < 0.05 and *** p < 0.001 vs the corresponding tumors. (C–E) Immunohistochemical staining of tumor tissues with NLRP1 (C), IL-1β (D), and Notch1 (E). Samples MB656, MB657, and MB658 were from the control group, whereas MB659, MB660, and MB661 were from the TMZ group. Bar = 50 μm (left panels, 20×) or 20 μm (right panels, 63×). Representative images are shown.
