Involvement of RNA Polymerase III in Immune Responses [PDF]

open access: yesMolecular and Cellular Biology, 2015
Inflammation in the tumor microenvironment has many tumor-promoting effects. In particular, tumor-associated macrophages (TAMs) produce many cytokines which can support tumor growth by promoting survival of malignant cells, angiogenesis, and metastasis. Enhanced cytokine production by TAMs is tightly coupled with protein synthesis. In turn, translation

Facilitated Recycling Pathway for RNA Polymerase III [PDF]

open access: yesCell, 1996
We show that the high in vitro transcription efficiency of yeast RNA pol III is mainly due to rapid recycling. Kinetic analysis shows that RNA polymerase recycling on preassembled tDNA.TFIIIC.TFIIIB complexes is much faster than the initial transcription cycle.

Chromatin remodeling by Pol II primes efficient Pol III transcription

open access: yesNature Communications, 2023
The packaging of the genetic material into chromatin imposes the remodeling of this barrier to allow efficient transcription. RNA polymerase II activity is coupled with several histone modification complexes that enforce remodeling.

Dystonia in RNA Polymerase III‐Related Leukodystrophy [PDF]

open access: yesMovement Disorders Clinical Practice, 2019
AbstractObjectivesTo identify the prevalence of dystonia in a RNA Polymerase III (POLR3)‐related leukodystrophy patient cohort and to further characterize their dystonic features.BackgroundPOLR3‐related leukodystrophy is a hypomyelinating leukodystrophy characterized by neurological and non‐neurological features.

A direct role of RNA polymerase III and RNA in DNA homologous recombination

open access: yesMolecular & Cellular Oncology, 2021
End resection excises several thousand bases from the 5ʹ-ended strand during DNA double-strand break repair, creating 3ʹ-end single-stranded DNA overhangs. This overhang requires strict protection from DNA2 or other nucleases digestion.

The choreography of chromatin in RNA polymerase III regulation. [PDF]

open access: yesBiochem Soc Trans
Regulation of eukaryotic gene expression involves a dynamic interplay between the core transcriptional machinery, transcription factors, and chromatin organization and modification. While this applies to transcription by all RNA polymerase complexes, RNA polymerase III (RNAPIII) seems to be atypical with respect to its mechanisms of regulation.

In vitro Assessment of RNA Polymerase I Activity

open access: yesBio-Protocol, 2017
In eukaryotic cells transcriptional processes are carried out by three different RNA polymerases: RNA polymerase I which specifically transcribes ribosomal RNA (rRNA), RNA polymerase II which transcribes protein-coding genes to yield messenger RNAs ...

Transcriptional response to VZV infection is modulated by RNA polymerase III in lung epithelial cell lines

open access: yesFrontiers in Cellular and Infection Microbiology, 2022
Ancestral RNA polymerase III (Pol III) is a multi-subunit polymerase responsible for transcription of short non-coding RNA, such as double-stranded short interspersed nuclear elements (SINEs).

Specific Features of RNA Polymerases I and III: Structure and Assembly

open access: yesFrontiers in Molecular Biosciences, 2021
RNA polymerase I (RNAPI) and RNAPIII are multi-heterogenic protein complexes that specialize in the transcription of highly abundant non-coding RNAs, such as ribosomal RNA (rRNA) and transfer RNA (tRNA).

Truncated PARP1 mediates ADP-ribosylation of RNA polymerase III for apoptosis

open access: yesCell Discovery, 2022
Caspase-mediated cleavage of PARP1 is a surrogate marker for apoptosis. However, the biological significance of PARP1 cleavage during apoptosis is still unclear.
