    Sulforaphane decreases serum selenoprotein P levels through enhancement of lysosomal degradation independent of Nrf2

    Selenoprotein P (SeP) is a major selenoprotein in serum predominantly produced in the liver. Excess SeP impairs insulin secretion from the pancreas and insulin sensitivity in skeletal muscle, thus inhibition o...

    Nrf2 inhibits hepatic iron accumulation and counteracts oxidative stress-induced liver injury in nutritional steatohepatitis

    The transcription factor nuclear factor-E2-related factor-2 (Nrf2) is a key regulator for induction of hepatic antioxidative stress systems. We aimed to investigate whether activation of Nrf2 protects against ...

    The selective autophagy substrate p62 activates the stress responsive transcription factor Nrf2 through inactivation of Keap1

    Impaired turnover of the autophagy substrate p62 leads to liver injury. p62 inhibits the ubiquitin ligase Keap1, leading to stabilization of the transcription factor Nrf2. High levels of p62 in autophagy defic...
