The Hidden Architects: Nitric Oxide and Redox Dynamics in Plant Stem Cell Homeostasis

open access: yesBioEssays, Volume 47, Issue 10, October 2025.
This review highlights the dynamic interplay between nitric oxide (NO) and reactive oxygen species (ROS) in regulating plant stem cell renewal and differentiation. NO and ROS integrate intrinsic factors like epigenetic and hormonal signals with extrinsic cues, including environmental stress and nutrient‐TOR signaling, to maintain meristem function and ...

Tailing and degradation of Argonaute-bound small RNAs protect the genome from uncontrolled RNAi

open access: yesNature Communications, 2017
While RNA interference is a highly conserved mechanism of gene regulation, how Argonaute-bound small RNAs are targeted for degradation is not well understood.

Rapid intraspecific evolution of miRNA and siRNA genes in the mosquito Aedes aegypti.

open access: yesPLoS ONE, 2012
RNA silencing, or RNA interference (RNAi) in metazoans mediates development, reduces viral infection and limits transposon mobility. RNA silencing involves 21-30 nucleotide RNAs classified into microRNA (miRNA), exogenous and endogenous small interfering

Structure and Function of Argonaute Proteins [PDF]

open access: yesStructure, 2005
Argonaute (Ago) family proteins are multidomain proteins expressed in prokaryotic and eukaryotic organisms. In eukaryotes, Ago proteins are most well known for their roles in RNA silencing. In prokaryotes, the functions of Ago proteins are unknown, but based on their similarity to eukaryotic Ago proteins, they could be involved in nucleic acid-directed

A Role for ARGONAUTE in Apomixis [PDF]

open access: yesThe Plant Cell, 2011
Apomixis is a form of asexual reproduction in angiosperms that results in the production of viable seed from maternal tissues of the ovule in the absence of meiosis and fertilization (reviewed in [Bicknell and Koltunow, 2004][1]).

MyomiRs Expression in Limb Girdle Muscular Dystrophy

open access: yesIUBMB Life, Volume 77, Issue 10, October 2025.
ABSTRACT This manuscript is a comprehensive review focused on the role of microRNAs (miRs)—short RNA molecules—in Limb Girdle Muscular Dystrophy (LGMD). LGMD encompasses various and heterogeneous rare genetic neuromuscular diseases, characterized by the progressive wasting and deterioration of muscle fibers, predominantly affecting the pelvic and ...

Argonaute proteins: potential biomarkers for human colon cancer

open access: yesBMC Cancer, 2010
Background Although Argonaute proteins are considered to play important roles in stem cell self-renewal, RNA interference (RNAi) and translational regulation, relatively little is known about their functions in human disease.
