| Study Title | Alignment and Analysis of a Disparately Acquired Multi-Batch Metabolomics Study of Maternal Pregnancy Samples. (Part 2) |
| Study Summary | This is an untargeted RPLC-MS metabolomics study of mother-infant pairs from the State of Michigan. Maternal plasma was collected in the first and third trimesters of gestation, as well as umbilical cord blood, with the aim of studying metabolic changes throughout pregnancy and influences on the infant's metabolome. The data is split into two experiment subsets, assayed with different H2O-methanol gradients and mass spectrometers 2-3 years apart, inducing major chromatographic and signal measurement shifts. Analysis steps consisted of disparate LC-MS alignment and data normalization, followed by differential timepoint comparisons and partial correlation network construction. |
