recovery from critical illness.The high-mobility-group (HMG) proteins are the most abundant non-histone chromatin-associated proteins. HMG proteins are present at high levels in various undifferentiated tissues during embryonic development and reduced in the corresponding adult tissues. We used used in study C57BL/6, HMG+/− and HMG−/− mice and found that HMG is expressed in the mouse embryonic kidney at the cortex area. HMG knockout led to enhanced Wnt/β-catenin signaling pathway. Analysis of siRNA-mediated loss-of-function experiments in embryonic kidney culture confirmed the role of HMG as a key regulator of cortex epithelium differentiation.
