eLife Assessment
This useful study uses the MMTV-Neu-YD5 mouse model for HER2-dependent breast cancer to generate transcriptomic and proteomic datasets from extracted primary tumour samples. The data sets generated appear to be solid and will be of interest to the community. However, mechanistic studies to support the conclusion that mitochondrial function is increased in the tumours remain incomplete and would benefit from experiments that would directly interrogate aspects such as cellular heterogeneity, and signalling.
