Rho-dependent transcription termination in bacteria recycles RNA polymerases stalled at DNA lesions
In bacteria, the Rho protein dislodges elongation complexes to terminate transcription, and the Mfd protein removes RNA polymerases (RNAPs) stalled at DNA lesions. Here, Jain et al.

Macrophages play an important role in regulating the tumor microenvironment (TME). Here we show that classical (M1) macrophage polarization reduced expression of LSD1, nuclear REST corepressor 1 (CoREST), and the zinc finger protein SNAIL.

Transcriptional enhancers: Transcription, function and flexibility [PDF]
Active transcriptional enhancers are often transcribed to eRNAs, whose changing levels mirror those of the target gene mRNA. We discuss some of the reported functions of these eRNAs and their likely diversity to allow utilization of distinct cis regulatory regions to enhance transcription in diverse developmental and cellular contexts.

The Transcription Factor Encyclopedia [PDF]
AbstractHere we present the Transcription Factor Encyclopedia (TFe), a new web-based compendium of mini review articles on transcription factors (TFs) that is founded on the principles of open access and collaboration. Our consortium of over 100 researchers has collectively contributed over 130 mini review articles on pertinent human, mouse and rat TFs.

One of the major ways of acquiring multidrug resistance in bacteria is via drug influx and efflux pathways. Here, we show that E. coli with compromised Rho-dependent transcription termination function has enhanced broad-spectrum antibiotic susceptibility,

Many Distinct Ways Lead to Drug Resistance in BRAF- and NRAS-Mutated Melanomas
Advanced melanoma is a relentless tumor with a high metastatic potential. The combat of melanoma by using the targeted therapy is impeded because several major driver mutations fuel its growth (predominantly BRAF and NRAS).

A newly demonstrated defect in RNA polymerase II termination caused by 7SK snRNA knockdown may have revealed a novel mechanism uncoupling RNA processing from transcription.

There is considerable evidence that transcription does not occur homogeneously or diffusely throughout the nucleus, but rather at a number of specialized, discrete sites termed transcription factories. The factories are composed of ~4-30 RNA polymerase molecules, and are associated with many other molecules involved in transcriptional activation and ...

Transcription Activation via Transcriptional Bursting [PDF]
Transcription factors (TFs) often regulate their own expression; monitoring TF production in real time will help elucidate autoregulatory mechanisms. However, many TFs are expressed at low levels and are difficult to detect. Further, labeling TFs with fluorescent proteins risks disrupting their regulatory functions. Here, we report a novel strategy, Co-

ERK2-topoisomerase II regulatory axis is important for gene activation in immediate early genes
The function of the mitogen-activated protein kinase signaling pathway is required for the activation of immediate early genes (IEGs), including EGR1 and FOS, for cell growth and proliferation.
