The role of post-transcriptional modifications during development

open access: yesBiologia Futura, 2022
AbstractWhile the existence of post-transcriptional modifications of RNA nucleotides has been known for decades, in most RNA species the exact positions of these modifications and their physiological function have been elusive until recently. Technological advances, such as high-throughput next-generation sequencing (NGS) methods and nanopore-based ...

An extended dsRBD is required for post-transcriptional modification in human tRNAs. [PDF]

open access: yesNucleic Acids Res, 2015
In tRNA, dihydrouridine is a conserved modified base generated by the post-transcriptional reduction of uridine. Formation of dihydrouridine 20, located in the D-loop, is catalyzed by dihydrouridine synthase 2 (Dus2). Human Dus2 (HsDus2) expression is upregulated in lung cancers, offering a growth advantage throughout its ability to interact with ...

Post-transcriptional modifications in development and stem cells [PDF]

open access: yesDevelopment, 2016
Cells adapt to their environment by linking external stimuli to an intricate network of transcriptional, post-transcriptional and translational processes. Among these, mechanisms that couple environmental cues to the regulation of protein translation are not well understood.

Distribution and frequencies of post-transcriptional modifications in tRNAs [PDF]

open access: yesRNA Biology, 2014
Functional tRNA molecules always contain a wide variety of post-transcriptionally modified nucleosides. These modifications stabilize tRNA structure, allow for proper interaction with other macromolecules and fine-tune the decoding of mRNAs during translation. Their presence in functionally important regions of tRNA is conserved in all domains of life.

Post-Transcriptional Modifications of RNA as Regulators of Apoptosis in Glioblastoma

open access: yesInternational Journal of Molecular Sciences, 2022
This review is devoted to changes in the post-transcriptional maturation of RNA in human glioblastoma cells, which leads to disruption of the normal course of apoptosis in them. The review thoroughly highlights the latest information on both post-transcriptional modifications of certain regulatory RNAs, associated with the process of apoptosis ...

Epigenetic regulation of miR-518a-5p-CCR6 feedback loop promotes both proliferation and invasion in diffuse large B cell lymphoma

open access: yesEpigenetics, 2021
To investigate the detailed functions and underlying mechanisms of miR-518a-5p/CCR6 in diffuse large B cell lymphoma (DLBCL) is needed. In this study, CCR6 expression levels were tested both in DLBCL cell lines and specimens.

Transcriptional regulation mediated through the conjugation and deconjugation of the small ubiquitin-like modifiers SUMO-1, SUMO-2, and SUMO-3 [PDF]

open access: yes, 2012
SUMO-1/2/3 are members of the ubiquitin-like family of protein modifiers. These proteins are covalently attached to numerous proteins in a directed and controlled manner.

Regulation of PD-L1 expression in the tumor microenvironment

open access: yesJournal of Hematology & Oncology, 2021
Programmed death-ligand 1 (PD-L1) on cancer cells engages with programmed cell death-1 (PD-1) on immune cells, contributing to cancer immune escape. For multiple cancer types, the PD-1/PD-L1 axis is the major speed-limiting step of the anti-cancer immune

Biosynthesis and functions of sulfur modifications in tRNA

open access: yesFrontiers in Genetics, 2014
Sulfur is an essential element for a variety of cellular constituents in all living organisms. In tRNA molecules, there are many sulfur-containing nucleosides, such as the derivatives of 2‑thiouridine (s2U), 4-thiouridine (s4U), 2-thiocytidine (s2C), and
