Characterization of ribosomal DNA (rDNA) in Drosophila arizonae
Genetics and Molecular Biology, 2000 Ribosomal DNA (rDNA) is a multigenic family composed of one or more clusters of repeating units (RU). Each unit consists of highly conserved sequences codifying 18S, 5.8S and 28S rRNA genes intercalated with poorly conserved regulatory sequences between ...

The Epigenetic Pathways to Ribosomal DNA Silencing [PDF]
Microbiology and Molecular Biology Reviews, 2016 SUMMARY Heterochromatin is the transcriptionally repressed portion of eukaryotic chromatin that maintains a condensed appearance throughout the cell cycle. At sites of ribosomal DNA (rDNA) heterochromatin, epigenetic states contribute to gene silencing and genome stability, which are required for proper chromosome segregation and

FEBS Open Bio, EarlyView.The cytoskeleton‐mediated transport of mitochondria via tunnelling nanotubes restores respiration, increases ATP production, rescues cells from apoptosis, activates the AKT/mTOR signalling pathway, promotes cell migration and invasiveness, contributes to cancer progression and treatment resistance.

Mutant NPM1 in Acute Myeloid Leukemia Initiation and Maintenance
Aging and Cancer, EarlyView.NPM1 mutations drive acute myeloid leukemia by acting as neomorphic transcriptional regulators that cooperate with Menin–MLL and XPO1 to sustain HOX/MEIS1 expression and block differentiation. Targeting these mutant‐specific transcriptional dependencies provides a rational therapeutic strategy for NPM1‐mutated AML.

A single, multiplex PCR for differentiating all species of Trichinella
Parasite, 2001 The genus Trichinella is currently divided into seven species and at least three additional, unclassified genotypes, Trichinella T6, T8 and T9, where both T8 and T9 have been deemed very similar to T. britovi. Other than for the non-encapsulated species,

RIBOSOMAL DNA IN A NUCLEAR SATELLITE OF TOMATO [PDF]
Genetics, 1975 ABSTRACT A satellite DNA of buoyant density 1.704 constitutes approximately 5%–6% of nuclear DNA isolated from cherry tomato leaves. Isolated satellite DNA exhibits a multi-component melting profile. Kinetic complexity measurements indicate that 37% of the satellite consists of repeating units of 105 daltons, and 48% of it consists of ...

Advanced Healthcare Materials, EarlyView.We measure the cell‐specific responses of administering infusible ECM (iECM) in acute myocardial infarction (MI) across multiple timepoints. Using single‐nucleus RNA sequencing and spatial transcriptomics, we measure macrophage activation, fibroblast remodeling, increased vascular development, lymphangiogenesis, cardioprotection, and neurogenesis ...

Genome-wide DNA methylation profiles and ribosomal DNA copy number at birth
EpigeneticsRibosomal DNA copy number (rDNAcn) and DNA methylation are important modulators of the human genome, both studied in relation to overall cellular function, biological ageing, and disease development.
