RNA processing in auxin and cytokinin pathways.

Journal of Experimental Botany, 2015
Auxin and cytokinin belong to the 'magnificent seven' plant hormones, having tightly interconnected pathways leading to common as well as opposing effects on plant morphogenesis.

An Overview of Pentatricopeptide Repeat (PPR) Proteins in the Moss Physcomitrium patens and Their Role in Organellar Gene Expression

Plants, 2022
Pentatricopeptide repeat (PPR) proteins are one type of helical repeat protein that are widespread in eukaryotes. In particular, there are several hundred PPR members in flowering plants.

Post-Transcriptional Control of RNA Expression in Cancer [PDF]

, 2018
Approximately 80% of the human genome contains functional DNA, including protein coding genes, non-protein coding regulatory DNA elements and non-coding RNAs (ncRNAs).

Post‐transcriptional processing at the promoter proximal RNA polymerase II pausing. A possible mechanism for premature termination

The FASEB Journal, 2019
Promoter‐proximal RNA Polymerase II pausing, which occurs within the first 100 nucleotides of a gene, refers to a property of the Polymerase II to halt transcription temporarily but remain transcriptionally competent. Knowledge of proximally paused Polymerase II dynamics is important for understanding the regulation of mRNA production.At the paused ...

Mycobacterial RNA isolation optimized for non-coding RNA: high fidelity isolation of 5S rRNA from Mycobacterium bovis BCG reveals novel post-transcriptional processing and a complete spectrum of modified ribonucleosides [PDF]

Nucleic Acids Research, 2014
A major challenge in the study of mycobacterial RNA biology is the lack of a comprehensive RNA isolation method that overcomes the unusual cell wall to faithfully yield the full spectrum of non-coding RNA (ncRNA) species. Here, we describe a simple and robust procedure optimized for the isolation of total ncRNA, including 5S, 16S and 23S ribosomal RNA (

Leveraging current insights on IL‐10‐producing dendritic cells for developing effective immunotherapeutic approaches

FEBS Letters, EarlyView.
In vivo IL‐10 produced by tissue‐resident tolDC is involved in maintaining/inducing tolerance. Depending on the agent used for ex vivo tolDC generation, cells acquire common features but prime T cells towards anergy, FOXP3+ Tregs, or Tr1 cells according to the levels of IL‐10 produced. Ex vivo‐induced tolDC were administered to patients to re‐establish/

Nanodynamo quantifies subcellular RNA dynamics revealing extensive coupling between steps of the RNA life cycle

Nature Communications
The coordinated action of transcriptional and post-transcriptional machineries shapes gene expression programs at steady state and determines their concerted response to perturbations.

Usb1 controls U6 snRNP assembly through evolutionarily divergent cyclic phosphodiesterase activities

Nature Communications, 2017
The mechanism of U6 small nuclear ribonucleoprotein (snRNP) biogenesis is not well understood. Here the authors characterize the enzymatic activities and structures of yeast and human U6 RNA processing enzyme Usb1, reconstitute post-transcriptional ...

Transcriptional and Post-Transcriptional Mechanisms of the Development of Neocortical Lamination

Frontiers in Neuroanatomy, 2017
The neocortex is a laminated brain structure that is the seat of higher cognitive capacity and responses, long-term memory, sensory and emotional functions, and voluntary motor behavior.
