Hierarchy of lesion processing governs the repair, double-strand break formation and mutability of three-lesion clustered DNA damage
Ionising radiation induces clustered DNA damage sites which pose a severe challenge to the cell's repair machinery, particularly base excision repair. To date, most studies have focussed on two-lesion clusters. We have designed synthetic oligonucleotides to give a variety of three-lesion clusters containing abasic sites and 8-oxo-7, 8-dihydroguanine to investigate if the hierarchy of lesion pro...
متن کاملBehavioural impact of a double dopaminergic and serotonergic lesion in the non-human primate.
Serotonergic (5-HT) neurons degenerate in Parkinson's disease. To determine the role of this 5-HT injury-besides the dopaminergic one in the parkinsonian symptomatology-we developed a new monkey model exhibiting a double dopaminergic/serotonergic lesion by sequentially using 1-methyl-4-phenyl-1,2,3,6-tetrahydropyridine (MPTP) and 3,4-methylenedioxy-N-methamphetamine (MDMA, better known as ecsta...
متن کاملA lesion-mimic syntaxin double mutant in Arabidopsis reveals novel complexity of pathogen defense signaling.
The lesion-mimic Arabidopsis mutant, syp121 syp122, constitutively expresses the salicylic acid (SA) signaling pathway and has low penetration resistance to powdery mildew fungi. Genetic analyses of the lesion-mimic phenotype have expanded our understanding of programmed cell death (PCD) in plants. Inactivation of SA signaling genes in syp121 syp122 only partially rescues the lesion-mimic pheno...
متن کاملDecreased atherosclerotic lesion formation in CX3CR1/apolipoprotein E double knockout mice.
BACKGROUND Fractalkine (CX3CL1), a CX3C chemokine, is expressed in the vessel wall and mediates the firm adhesion and chemotaxis of leukocytes expressing its receptor, CX3CR1. A polymorphism in the CX3CR1 gene is associated with low CX3CR1 expression and reduced risk of acute coronary disease in humans. METHODS AND RESULTS We generated CX3CR1-deficient mice (CX3CR1(-/-)) by targeted gene disr...
متن کاملOptical coherence tomography assessment of a complex bifurcation lesion treated with double kissing Crush technique
The DEFINITION (Impact of the complexity of bifurcation lesions treated with drug-eluting stents) study has provided a novel classification to evaluate the complexity of coronary bifurcation lesion according to coronary angiography, but angiographic imaging due to its low resolution and inherited limitation may result in an inaccurate adjudication.We used optical coherence tomography (OCT) to f...
