Calculation of an activation z-score was used to infer the activation states of pathways. Genes were categorized into functional clusters and network analysis was done by Ingenuity Pathway Analysis (IPA). ACTIVATION Z‐SCORE The primary purpose of the activation z‐score is to infer the activation states (“increased” or “decreased”) of While the calculated z-score varied for the comparisons examined, beta-estradiol was the only upstream regulator common to all of the comparisons. Ingenuity pathway analysis of the exosomal proteins revealed differential expression of the proteins targeting the sirtuin signaling pathway, oxidative phosphorylation, and mechanistic target of rapamycin signaling pathway in GDM … ���W�4g�nғ�Q��R�T����|���[� �R An absolute z-score ≥2 is considered 0 Z-score: The activation z-score predicts the activation state of the QIAGEN IPA canonical pathway, using the gene expression patterns of the genes within the pathway.

To choose the best pathway analysis method, one should consider the following four crucial factors in order of importance: (i) number of biased pathways; (ii) ranking of the target pathways; (iii) AUC, accuracy, sensitivity, and specificity; and finally (iv) p values of the target pathways. h�27W0P0�P01Q0�T045U���w�/�+Q04���L)��(���T�~HeA�~@bzj��B�D��1X�!�4�݆F�BA� � Results: The number of exosomes (vesicles/μg of tissue/24 hours) was substantially (1.7-fold) greater in GDM than in NGT, and the number of exosomes correlated positively with the birthweight Z score. Analysis of up and downregulated genes after PO 2 oscillation was also performed with respect to canonical pathways using IPA.
