Liver fibrosis

Disease2 papers4 findings

In mouse studies, alternate-day fasting and Camellia sinensis extract reduce liver fibrosis, with fasting-mediated protection requiring hepatocyte Nos3. Conversely, hepatocyte-specific knockout of NOS3 increases liver fibrosis.

  1. NOS3 knockout increases liver fibrosis in mice.

    “In human fibrotic liver samples and mouse models, eNOS expression is markedly suppressed, and its hepatocyte-specific deletion aggravates injury and fibrosis.”

  1. Intermittent fasting protects against liver fibrosis in mice.

    “We further establish that the anti-fibrotic benefits of alternate-day fasting (ADF) critically depend on this intercellular pathway.”
