As Anpep also prevents cellular toxicity from Cys-Gly dipeptide accumulation in addition to promoting cysteine and glycine recovery, we next measured urinary Anpep levels using LC-MS in MRM mode (Figure 3C, peptide determination results are shown in Supplementary Tables S9)

A review study proposed another mechanisms underlying the potential interaction of the smoking and oestrogen metabolites such as decrease in oestrogen activity, SHBG levels, aromatase enzyme activity, C-20, 22 desmolase enzyme levels and increase in free testosterone levels, hyperandrogenism and the hepatic metabolism of steroid (Reference Ruan and Mueck41)

Although phosphate is essential for cellular metabolism, its excessparticularly under conditions of impaired renal excretionbecomes pathogenic (Gao et al., 2015)

Because it's investigational and potent, its long-term human safety isn't fully established
