CH25H and diabetes mellitus: Diabetes‐induced albuminuria, assessed by the urinary albumin–creatinine ratio (UACR) of bi‐weekly collected spot urine samples between 8 to 24 weeks of age (Figure 2a) and total 24‐hour urine albumin excretion (UAE) at 24 weeks of age (Figure 2b) were markedly higher in Leprdb/db/Ch25h−/− mice in comparison to Leprdb/db/Ch25h+/+ mice.
