HEMOPOIESIS IN RIBOFLAVIN-DEFICIENT RATS [PDF]

Blood, 1947
Abstract Leukopenia, granulocytopenia, and, occasionally, anemia develop in rats fed a purified diet deficient in riboflavin. Folic acid (L. casei factor) corrects the leukopenia and granulocytopenia. Riboflavin will prevent all the dyscrasias but will correct only the anemia.

Enhanced mitochondrial activity reshapes a gut microbiota profile that delays NASH progression

Hepatology, EarlyView., 2022
Improved mitochondrial activity, due to the lack of methylation‐controlled J protein (MCJ), creates a specific microbiota signature that when transferred through cecal microbiota transplantation delays NASH progression by restoring the gut‐liver axis and enhancing hepatic fatty acid oxidation.
