Identification of Metabolites of the Dietary Supplement Ingredient 5α‐Hydroxy‐Laxogenin

open access: yesDrug Testing and Analysis, EarlyView.
The biotransformation of the dietary supplement ingredient 5α‐hydroxy‐laxogenin was investigated using human HepG2 cells, the rat and in silico using the online software Next‐gen E‐Resource for Drug Discovery (NERDD). We identified five metabolites generated by the human HepG2 cells of which three and an additional mono‐hydroxylated metabolite were ...

Streptozotocin induced hyperglycemia in the axolotl

open access: yesDevelopmental Dynamics, EarlyView.
Abstract Background Diabetes is a group of diseases characterized by loss of β cell mass and/or function, resulting in hyperglycemia. With no established curative treatment, this has initiated research in β cell regeneration. Current animal models have either limited regenerative capacity (mice) or small size and evolutionary distance from humans ...
