Ultrafine anaphase bridges, broken DNA and illegitimate recombination induced by a replication fork barrier [PDF]

, 2011
Most DNA double-strand breaks (DSBs) in S- and G2-phase cells are repaired accurately by Rad51-dependent sister chromatid recombination. However, a minority give rise to gross chromosome rearrangements (GCRs), which can result in disease/death.

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 ...

Gut Microbiota Regulates Systemic Inflammatory Response and Compensatory Anti‐Inflammatory Response Syndromes by Targeting PF4+ Macrophages in Acute Pancreatitis

Advanced Science, EarlyView.
ABSTRACT Acute pancreatitis (AP) begins with pancreatic local inflammation, leading to the onset of systemic inflammatory response syndrome (SIRS), followed by compensatory anti‐inflammatory response syndrome (CARS), which causes immune paralysis and higher mortality rate.

Generation of a ribosomal DNA probe by PCR and its use in identification of fungi within the Gaeumannomyces - Phialophora complex

, 1992
The polymerase chain reaction (PCR) was used to amplify a ribosomal DNA fragment from Gaewnannomyces graminis. This fragment was labelled and tested for its usefulness as a probe in restriction fragment length polymorphism (RFLP) studies of fungi within ...

Molecular and ultrastructure characterization of two nematodes (Thelandros scleratus and Physalopteroides dactyluris) based on ribosomal and mitochondrial DNA sequences

Helminthologia, 2016
The phylogenetic relationships of the nematode species Thelandros scleratus (Oxyurida: Pharyn-godonidae) and Physalopteroides dactyluris (Spirurida: Physalopteridae) were analyzed using the ribosomal 18S rRNAand the mitochondrial cytochrome C oxidase ...

ABH2 Couples Regulation of Ribosomal DNA Transcription with DNA Alkylation Repair

Cell Reports, 2013
Transcription has been linked to DNA damage. How the most highly transcribed mammalian ribosomal (rDNA) genes maintain genome integrity in the absence of transcription-coupled DNA damage repair is poorly understood.

TRMT6‐Mediated m1A Modification of CDK9 mRNA Is a Dual‐Pronged Pathogenic Driver for HBV‐Related Hepatocellular Carcinoma

Advanced Science, EarlyView.
TRMT6‐mediated m1A modification in CDK9 mRNA enhances its mRNA stability and translation efficiency, thereby increasing the protein levels of CDK9. Upregulated CDK9 promotes the progression of HCC by elevating the levels of oncogenic factors including p‐STAT3, MCL1, and BCL‐2. On the other hand, CDK9 phosphorylates TARDBP at Ser254 to activate HBV core

SCREENING OF SECONDARY METABOLITE-PRODUCING BACTERIA ASSOCIATED WITH CORALS USING 16S rDNA-BASED APPROACH [PDF]

, 2003
A total of 42 coral-associated bacteria were screened for their ability to produce secondary metabolites by using 16S rDNA-based approach. A specific oligonucleotides primer was used to amplify DNA non-ribosomal peptide synthetase (NRPS).

Mitochondrial and nuclear genes suggest that stony corals are monophyletic but most families of stony corals are not (Order Scleractinia, Class Anthozoa, Phylum Cnidaria) [PDF]

, 2008
Modern hard corals (Class Hexacorallia; Order Scleractinia) are widely studied because of their fundamental role in reef building and their superb fossil record extending back to the Triassic.

Paternal Circadian Disruption Impairs Offspring Cognition via Sperm microRNAs

Advanced Science, EarlyView.
Paternal circadian disruption remodels the sperm small RNA payload, elevating miR‐92a‐3p/miR‐25‐3p levels and perturbing early embryonic gene regulatory programs. Microinjection experiments and single‐embryo transcriptomics reveal sex‐specific developmental vulnerabilities, ultimately impairing offspring hippocampal synaptic plasticity and cognition ...
