UBR box-containing ubiquitin E3 ligases recognize the N-termini of their target proteins through the UBR box, and a member of the family, UBR2, has been established as a target to treat cancer- and diabetes-associated cachexia. However, the development of high-affinity...
BACKGROUNDS
Muscle atrophy, characterized by progressive loss of muscle mass and function, is driven by muscle-specific E3 ligases MAFbx and MuRF1. While transcriptional regulation of E3 ligases is documented, the mechanism of their regulation by the ubiquitin-proteasome system remains unclear. This...
Maintaining skeletal muscle mass and strength is crucial to prevent sarcopenia during healthy ageing. Ankyrin repeat and suppressor of cytokine signalling box protein 2 (Asb2), an E3 ligase, has been implicated in regulating muscle mass; however, its roles on muscle...
Anticancer chemotherapy is an underappreciated contributor to cancer cachexia, an often-irreversible body-wasting condition that causes 20%-30% of cancer-related deaths. An obstacle to predicting, monitoring and understanding the mechanisms underlying chemotherapy cachexia is that each cancer (and subtype) is assigned different...
G protein-coupled receptor 40 (GPR40) acts as a modulator of various physiological functions, including glycaemic lowering, anti-inflammation and antioxidative stress, in several tissues. However, the role of GPR40 in skeletal muscles remains unclear. To investigate the roles of muscle GPR40,...
While decreased protein intake is associated with muscle mass loss, it is unclear whether a decrease in carbohydrate intake adversely affects muscle atrophy independently of protein intake. Herein, we examined whether a low-carbohydrate (low-CHO) diet exacerbates denervation-induced muscle atrophy under...
