Pre‐ and post‐puberty expression of genes and proteins in the uterus of Bos indicus heifers: the luteal phase effect post‐puberty

Summary Progesterone signaling and uterine function are crucial in terms of pregnancy establishment. To investigate how the uterine tissue and its secretion changes in relation to puberty, we sampled tissue and uterine fluid from six pre‐ and six post‐pubertal Brahman heifers. Post‐pubertal heifers were sampled in the luteal phase. Gene expression of the uterine tissue was investigated with RNA‐sequencing, whereas the uterine fluid was used for protein profiling with mass spectrometry. A total of 4034 genes were differentially expressed (DE) at a nominal P‐value of 0.05, and 26 genes were significantly DE after Bonferroni correction (P
