Our findings show that for a major class of genes - those housekeeping genes that make ribosomes, proteasomes and other essential structures - cells employ very simple modes of gene expression that require much less coordination than previously thought," said Saumil Gandhi, the lead author of the study.
0 ppm ATR, expression of the housekeeping genes actin and tubulin was reduced, as well as expression of GH and LH [Figure 1; see also Supplemental Material, Figure 2 (doi:10.
Due to the responsibility to maintain the cellular environment, housekeeping genes are endowed with a chromatin region that is always open to the cell's translation machinery, and the UCOE technology uses a novel approach that harnesses these key regulatory DNA elements associated with the housekeeping genes to perform a similar function when incorporated with proprietary expression vectors.
