Example of the dynamic expression of a specific gene product (STAR mRNA, relative units) during the lifespan of the macaque corpus luteum, plus the effects of LH depletion during the menstrual cycle and hCG administration during simulated early pregnancy. Similar data analyses can be generated for any number of genes of interest from the publically available NCBI GEO databases (e.g., GSE2276, GSE10367, GSE25335). Data adapted from [9, 76, 92].
