Obese individuals are at high risk of developing kidney disease, which can lead to renal failure requiring dialysis or transplant. Few models of obesity-associated kidney disease exist, so investigating the association has been a challenge. Martínez-García et al. now report a model that enables the study of kidney disease in the context of obesity. They crossed ob/ob mice (which store large amounts of fat) with mice lacking PPARγ (which are impaired in generating fat tissue) to generate ‘POKO mice’, which have high circulating levels of glucose and fat. At just 4 weeks old, POKO mice show kidney dysfunction associated with inflammation, fibrosis and lipid accumulation – all signs of advanced kidney disease. Kidney pathology advances to severe by 12 weeks. These data introduce the POKO mouse as a new model of obesity-associated kidney disease, and indicate that glucolipotoxicity can accelerate the condition. Page 636

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
We are now accepting proposals for our 2025 Biologists 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 (GS) country to host an event overseas.
At a Glance - in vitro cardiac models
In our recent At a Glance feature Lika Drakhlis and Robert Zweigerdt provide an overview of in vitro cardiac models, their advantages and limitations and their applications for disease modelling and therapeutic development.
Perspective - Designer pigs for xenogeneic heart transplantation and beyond
Xenotransplantation of porcine hearts is a potential option for patients who cannot receive human organs. Eckhard Wolf and colleagues elaborate on how genetically engineered pigs can provide a powerful platform for restoration of cardiac function.
