a, Blood glucose levels of CRC-tumour-bearing mice after sham and BAT removal under 30 °C or 4 °C. n = 8 mice per group. b, CRC tumour growth rates in sham and BAT-removed mice under 30 °C or 4 °C conditions. n = 10 mice per group. c, Tumour growth curves of BAT-removed MMTV-PyMT mice under 30 °C and 4 °C conditions. n = 6 mice per group. d, Representative PET–CT images and quantification of SUV-BW of BAT-removed MMTV-PyMT mice under 30 °C or 4 °C conditions. n = 6 mice per group. Scale bar, 5 mm. e, Immunofluorescence staining of tumours grown in BAT-removed MMTV-PyMT mice with CA9+ hypoxic area, Ki-67+ proliferating cells, CD31+ microvessels and Cl-Casp3+ apoptotic cells. The arrows and arrowheads indicate the respective positive signals. Tumour tissues were counterstained with DAPI (blue). Scale bars, 50 μm. f, Quantification of positive signals of the markers presented in e. n = 6 random fields per group. For ad and f, data are mean ± s.e.m. Statistical analysis was performed using one-way analysis of variance (ANOVA) followed by Tukey multiple-comparison test (a and b) and two-sided unpaired t-tests (c, d and f).
