Abstract

c-Myc has been proposed as a putative target gene of signal transducer and activator of transcription 5 (STAT5). No functional STAT5 binding site has been identified so far within the c-Myc gene locus, therefore a direct transcriptional regulation by STAT5 remains uncertain. c-Myc super-enhancer, located 1.7 Mb downstream of the c-Myc gene locus, was recently reported as essential for the regulation of c-Myc gene expression by hematopoietic transcription factors and bromodomain and extra-terminal (BET) proteins and for leukemia maintenance. c-Myc super-enhancer is composed of five regulatory regions (E1-E5) which recruit transcription and chromatin-associated factors, mediating chromatin looping and interaction with the c-Myc promoter. We now show that STAT5 strongly binds to c-Myc super-enhancer regions E3 and E4, both in normal and transformed Ba/F3 cells. We also found that the BET protein bromodomain-containing protein 2 (BRD2), a co-factor of STAT5, co-localizes with STAT5 at E3/E4 in Ba/F3 cells transformed by the constitutively active STAT5-1*6 mutant, but not in non-transformed Ba/F3 cells. BRD2 binding at E3/E4 coincides with c-Myc transcriptional activation and is lost upon treatment with deacetylase and BET inhibitors, both of which inhibit STAT5 transcriptional activity and c-Myc gene expression. Our data suggest that constitutive STAT5 binding to c-Myc super-enhancer might contribute to BRD2 maintenance and thus allow sustained expression of c-Myc in Ba/F3 cells transformed by STAT5-1*6.

Attention Score in Context

Attention Score in Context

This research output has an Altmetric Attention Score of 2. This is our high-level measure of the quality and quantity of online attention that it has received. This Attention Score, as well as the ranking and number of research outputs shown below, was calculated when the research output was last mentioned on 28 July 2016.
All research outputs
#16,048,009
of 25,374,647 outputs
Outputs from BMC Molecular and Cell Biology
#700
of 1,233 outputs
Outputs of similar age
#173,091
of 315,339 outputs
Outputs of similar age from BMC Molecular and Cell Biology
#5
of 22 outputs
Altmetric has tracked 25,374,647 research outputs across all sources so far. This one is in the 34th percentile – i.e., 34% of other outputs scored the same or lower than it.
So far Altmetric has tracked 1,233 research outputs from this source. They receive a mean Attention Score of 4.0. This one is in the 40th percentile – i.e., 40% of its peers scored the same or lower than it.
Older research outputs will score higher simply because they've had more time to accumulate mentions. To account for age we can compare this Altmetric Attention Score to the 315,339 tracked outputs that were published within six weeks on either side of this one in any source. This one is in the 42nd percentile – i.e., 42% of its contemporaries scored the same or lower than it.
We're also able to compare this research output to 22 others from the same source and published within six weeks on either side of this one. This one has gotten more attention than average, scoring higher than 63% of its contemporaries.
