It is possible that the position of the Pax6 binding sites in regions that exert primary roles in controlling the expression profile of these Hox genes has led to their conservation in Ciona and vertebrates.
In E. coli cells, genome methylation patterns are known to act as epigenetic memory that controls the expression profile [ 36, 37], as well as the binding of histone-like proteins, such as H-NS and Fis, to genomic DNA [ 38, 39].
The structural genes are regulated at the transcriptional level by regulatory genes, and thus plant pigmentation patterns are mainly controlled by the expression profiles of regulatory genes [ 11, 12].
In MEFs infected with a control vector, the expression profiles of P and A&P targets were statistically different from non-target genes (p < 0.05, two-sample Kolmogorov Smirnov test; Fig. 5b).
Because Dhahbi and collaborators used only old CR male mice to compare to old and young normal controls, the expression profile differences reported by these authors are expected to be equivalent to those from old CR females.
Regulation of mRNA degradation is an important mechanism controlling the gene expression profile.
The cluster analyses revealed complete separation of the patient and control groups based on the expression profiles of the differentially expressed miRNAs.
Some research groups have investigated the levels of A β42 and A β40 in plasma from AD patients in attempt to develop a specific biomarker; however, there was no significant difference between AD patients and controls for the expression profile of these peptides [ 18].
To stratify iCD and iUC samples from the healthy controls, we also compared the expression profiles of the top 20 up/down-regulated lncRNAs and the top 20 up/down-regulated protein-coding genes (based on FC) through unsupervised hierarchical clustering.
In this regard, a new transgenic system is needed to suppress MGD1 only in flowers with, for example, chemically inducible promoter-driven RNAi to control the spatiotemporal expression profiles of MGDG.
