Figure 4. Quantification of selected ions identified by UPLC-ESI-QTOF-MS based metabolomics.
Metabolite concentrations were determined by triple-quadrupole mass spectrometry and normalized to millimoles of creatinine for urine samples (A–D) and to milligrams of tissue weight for liver samples (E). P-values for differences in metabolite concentrations between genotypes are indicated (* = statistically significant, p<0.05). PAG: Phenylacetylglycine. WT: Hmgn5+/y; N5KO: Hmgn5tm1/Y. Analyses were done with 7 N5KO and 5 WT mice.
