In vivo ChIP analyses with both Spt5 and RNAPII antibodies on a select set of genes further identify targets that are regulated either by the repressive or by the stimulatory activity of Spt5 at the level of transcription elongation.
A summary of non-coding RNAs regulated either at FC30' and RT30' can be found in Additional file 11.
Category IV contains genes that were regulated – either up or down – in each of the cell types in response to LTβR stimulation (Table 9).
p27Kip1 in resistant cells could not be regulated either in response to serum or rapamycin, and as a result, RB phosphorylation was not blocked.
Category III contains genes that were regulated – either up or down – in wt and relB-/ cells in response to LTβR stimulation.
11,262 of all features on the microarrays appeared as differentially regulated either upon DTT treatment or HAC1 overexpression, or both.
From what is known from other rhizobia genera, only some groESL operons encoded in the same genome are heat inducible and those can be regulated either by the σ or by CIRCE element.
Alternatively, this could reflect that, as less abundant messages tend to be those that are more tightly regulated, either a dysregulation of accumulation or a regulated stress response to shutoff could be at work.
