Together, these suggest that the pathogenic mycobacteria actively express the PE/PPE genes during infection and their regulation and expression correlates not only with pathogenicity but also with the specificity of the host thereby indicating that the expression or secretion of the PE/PPE genes is confined to the pathogenic mycobacteria.
Given that the aorta contain cells of myocardial origin and actively express muscle-specific markers, it is possible that these cells generate the active tension necessary for clinical closing pressure.
As a result, only the cells near the edge of the light-exposed area actively express lacZ, which results in a dark pigment due to the enzymatic cleavage of a substrate in the plate by LacZ.

It is possible that an actively expressed gene can suppress the expression of a close-by gene, especially a weakly expressed gene.
Similarly, specific histone modifications may distinguish actively expressed genes from genes that are poised for expression or genes that are repressed in different kinds of cells.
