Cachexia, characterised by weight loss, muscle atrophy and fatigue, occurs in many individuals with cancer and causes more than 20% of cancer-related deaths. Animal models of the condition exist, but many of their phenotypes have not been comprehensively characterised. Murphy et al. analysed colon-26 (C-26) tumour-bearing mice, a common mouse model of cancer cachexia, for functional and metabolic defects: they find impairments in tests of physical activity, as well as reduced strength and increased fatigability of muscle tissues. Moreover, these mice have metabolic impairments such as reduced oxygen uptake and increased fat oxidation. This characterisation should help to identify relevant end points for future studies, and supports the continued use of C-26 tumour-bearing mice as model for human cancer cachexia. Page 533

The Forest of Biologists
The Forest of Biologists is a biodiversity initiative created by The Company of Biologists, with support from the Woodland Trust. For every Research and Review article published in Disease Models & Mechanisms a native tree is planted in a UK forest. In addition to this we are protecting and restoring ancient woodland and are dedicating these trees to our peer reviewers. Visit our virtual forest to learn more.
Propose a new Workshop for 2025
Do you have an idea for a Workshop? If so, click here. We are now accepting proposals for our 2025 Workshops programme. As the scientific organiser, your involvement will be focused on the science. We'll take care of all the logistics. In 2025 we'll continue our efforts to diversify our Workshop programme and will be reserving one of our Workshops for an application from a Global South country to host an event overseas.
How stromal cells restrict liver cancer invasion
In our recent editor’s choice, Liqin Zhu and colleagues describe how they used in vitro liver spheroid models consisting of both parenchymal and non-parenchymal cells to reveal a hepatoprotective role for peritumoral hepatic stellate cells in liver tumorigenesis.
And from perspective… Hacking haematopoiesis – emerging tools for examining variant effects
Thousands of genomic loci have been linked to hematopoietic traits and diseases, yet many await functional validation. Michael Gundry and Vijay G. Sankaran discuss recent advances in genome editing and the challenges associated with using these techniques to assess variant function in primary hematopoietic cells.
