Effects of mulberry leaf-related extracts (MLREs) on hydrogen peroxide-induced DNA damage in human lymphocytes and on inflammatory signaling pathways in human aortic endothelial cells (HAECs) were studied. The tested MLREs were rich in flavonols, especially bombyx faces tea (BT) in quercetin and kaempferol. Polyphenols, flavonoids, and anthocyanidin also abounded in BT. The best trolox equivale...

The tumor suppressor protein p53 localizes to microtubules (MT) and, in response to DNA damage, is transported to the nucleus via the MT minus-end-directed motor protein dynein. Dynein is also responsible for MT-mediated nuclear targeting of adenovirus type 2 (Ad2). Here we show that treatment with low concentrations of MT-targeting compounds (MTCs) that do not disrupt the MT network but are kn...

ataxia-telangiectasia (at) is a rare human neurodegenerative autosomal recessive multisystem disease characterized by a wide range of features including progressive cerebellar ataxia during infancy, occulocutaneous telangiectasia, susceptibility to neoplasia, occulomotor disturbances, chromosomal instability and growth and developmental abnormalities. mitochondrial dna (mtdna) has the only non-...

TET2 enzymatically converts 5-methylcytosine to 5-hydroxymethylcytosine as well as other covalently modified cytosines and its mutations are common in myeloid leukemia. However, the exact mechanism and the extent to which TET2 mutations affect DNA methylation remain in question. Here, we report on DNA methylomes in TET2 wild-type (TET2-WT) and mutant (TET2-MT) cases of chronic myelomonocytic le...

The transposition of parts of the mitochondrial (mt) genetic material into the nuclear genome (NUMTs) occurs in a wide range of eukaryotes. Here, we show that NUMTs exist for nearly all regions of the mt genome in the demosponge Amphimedon queenslandica, a representative of the oldest phyletic lineage of animals. Because the sponge NUMTs are small and noncoding, and transposed via a DNA interme...

Accurate and reliable quantification of the abundance of mitochondrial DNA (mtDNA) molecules, both wild-type and those harbouring pathogenic mutations, is important not only for understanding the progression of mtDNA disease but also for evaluating novel therapeutic approaches. A clear understanding of the sensitivity of mtDNA measurement assays under different experimental conditions is theref...

We applied multiplex-tandem PCR (MT-PCR) to 255 EDTA whole-blood specimens, 29 serum specimens, and 24 plasma specimens from 109 patients with Candida bloodstream infection (candidemia) to determine whether a diagnosis could be expedited in comparison with the time to diagnosis by the use of standard blood culture. Overall, the MT-PCR performed better than blood culture with DNA extracted from ...

Pathogenic mitochondrial tRNA (mt-tRNA) gene mutations represent a prominent cause of primary mitochondrial DNA (mtDNA)-related disease despite accounting for only 5%-10% of the mitochondrial genome.(1,2) Although some common mt-tRNA mutations, such as the m.3243A>G mutation, exist, the majority are rare and have been reported in only a small number of cases.(3) The MT-TP gene, encoding mt-tRNA...
