Evolutionarily conserved temperature dependency leads to loss of protein O-GlcNAc in mammalian hypothermia

Divya Upadhyay, Christa Kietz, Nasrin Sultana…·Jukka Kallijärvi

This study identifies temperature as an evolutionarily conserved regulator of O-GlcNAcylation, showing that hypothermia reduces O-GlcNAc levels across species.

Hepatic mitochondrial respiration is crucial for euthermia in complex III-deficient mice with impaired brown adipose tissue thermogenesis

Rishi Banerjee, Divya Upadhyay, Tomáš Zárybnický…·Jukka Kallijärvi

This study shows that restoring mitochondrial complex III function in the liver of CIII-deficient mice prevents hypothermia and improves survival by enabling normal thermoregulation.
