We identified a comparative up regulation of three biological processes generation of precursor metabolites and energy, transport, and cell communication in cumulus cells compared to oocytes.
From GO associations of differentially expressed proteins we found that there was a comparative up regulation of three biological processes in high fertility spermatozoa: metabolism, cell communication and cell motility (Fig 2).
While studies relying on cis-regulatory sequences are more prevalent, functional studies of comparative gene regulation are beginning to shed light on how regulatory evolution is linked to functional changes.
Conversely, large-scale interspecific comparative gene regulation studies in the context of development are lacking, despite a growing body of speculation about the importance of divergence in regulatory networks in determining broad evolutionary patterns [ 3, 4].
Our experiments showed comparative up-regulation of CNN3, RGS1 and F13A1 and down-regulation of BTG2 and ID3 in our ICF cell lines, confirming previous results obtained by microarray analysis [21].
A comparative plot of regulation amplitudes of the 5844 genes passing quality control in both datasets showed reasonable similarity in regulation amplitude between starve-synchronized and DCE-selected cells, given the differences in synchronization and detection methods and the time-points analyzed (Fig. 2C; R-squared = 0.25).
Peterson's elevator pitch is that the NASL has a low barrier for entry, and a lack of regulation comparative to MLS, which makes it a less complicated investment for any party looking to put money into North American soccer.
Our focus on biology and medicine will cover: pharmacology/pharmacogenomics; stem cell biology; cell biology of cancer; the immune system; and metabolism, comparative genomics, gene regulation, and liver biology.
In addition, by juxtaposing these microarray findings with DNA comparative algorithms, the regulation of genes co-ordinately expressed in specific spatial and temporal patterns can be studied at a mechanistic level.
Comparative analysis of gene regulation by Wy14643 between human liver slices and primary human hepatocytes showed that down-regulation of gene expression by PPARα is much better captured by liver slices as compared to primary hepatocytes.
