Identification of General and Heart-Specific miRNAs in Sheep (Ovis aries).

open access: yesPLoS ONE, 2015
MicroRNAs (miRNAs or miRs) are small regulatory RNAs crucial for modulation of signaling pathways in multiple organs. While the link between miRNAs and heart disease has grown more readily apparent over the past three years, these data are primarily ...

LIN28 Zinc Knuckle Domain Is Required and Sufficient to Induce let-7 Oligouridylation

open access: yesCell Reports, 2017
LIN28 is an RNA binding protein that plays crucial roles in pluripotency, glucose metabolism, tissue regeneration, and tumorigenesis. LIN28 binds to the let-7 primary and precursor microRNAs through bipartite recognition and induces degradation of let-7 ...

Diversification of multipotential postmitotic mouse retinal ganglion cell precursors into discrete types

open access: yeseLife, 2022
The genesis of broad neuronal classes from multipotential neural progenitor cells has been extensively studied, but less is known about the diversification of a single neuronal class into multiple types.

Precursors to small molecular weight RNA components [PDF]

open access: yesFEBS Letters, 1975
Metabolically long-lived RNA components such as tRNA and rRNA are formed from unstable larger precursors [ 1,2] . Baby Hamster Kidney cells (BHK-2 1 cells) contain four small mol. wt RNA components (sm RNA) with a metabolic half-life of 5-7 days [3] . The size of these components (D, C, A, and L) was determined to be from 145 to 235 nucleotides based ...

Diversity and complexity in neural organoids

open access: yesFEBS Letters, EarlyView.
Neural organoid research aims to expand genetic diversity on one side and increase tissue complexity on the other. Chimeroids integrate multiple donor genomes within single organoids. Self‐organising multi‐identity organoids, exogenous cell seeding, or enforced assembly of region‐specific organoids contribute to tissue complexity.

The RNA Polymerase II-associated factor 1 complex represses small-RNA-mediated heterochromatin formation and gene silencing [PDF]

open access: yes, 2015
RNAi interference (RNAi) is a highly conserved regulatory mechanism employed by almost all Eukaryotes. With RNAi organisms can modulate the expression of endogenous genes and protect the integrity and identity of their genomes.

The H/ACA complex disrupts triplex in hTR precursor to permit processing by RRP6 and PARN

open access: yesNature Communications, 2018
Telomerase RNA (hTR) is transcribed as a 3′-extended precursor. Here the authors examine the processing of hTR precursors of various lengths and show that processing occurs in distinct steps involving different nucleases PARN and RRP6.

Primary and secondary siRNAs in geminivirus-induced gene silencing. [PDF]

open access: yesPLoS Pathogens, 2012
In plants, RNA silencing-based antiviral defense is mediated by Dicer-like (DCL) proteins producing short interfering (si)RNAs. In Arabidopsis infected with the bipartite circular DNA geminivirus Cabbage leaf curl virus (CaLCuV), four distinct DCLs ...

MapToCleave: High-throughput profiling of microRNA biogenesis in living cells

open access: yesCell Reports, 2021
Summary: Previous large-scale studies have uncovered many features that determine the processing of microRNA (miRNA) precursors; however, they have been conducted in vitro.

Epigenetic blind spots – the role of DNA methylation dynamics in stem cell‐based models of embryogenesis

open access: yesFEBS Letters, EarlyView.
Embryo‐like structures (stembryos) are an innovative tool, but they are hindered by experimental variability and limited developmental potential. DNA methylation is crucial for mammalian development, but its status in stembryo models is poorly characterized.
