Data‐Independent Acquisition Mass Spectrometry in Tumor Classification and Cancer Biomarker Research
Mass Spectrometry Reviews, EarlyView.Abstract Cancer treatment is far from optimal also because current classification systems do not reflect the complex molecular status of the tumor and its phenotype in sufficient detail. To construct molecular tumor classifiers, omics tools provide complex molecular data reflecting many aspects from genotype to phenotype.

Ion Activation Methods for Top‐Down Proteomics
Mass Spectrometry Reviews, EarlyView.ABSTRACT Mass spectrometry (MS) has emerged as a premier method used to characterize the sequences of proteins. Top‐down proteomics aims to capture the multiple sources of structural diversity reflected in proteins, such as those that arise from alternative RNA splicing events or the addition of post‐translational modifications. Tandem MS (i.e., MS/MS)

Structure and organization of ribosomal DNA
Biochimie, 1991Three trends are seen in the organization of ribosomal DNA genes during evolution: 1) gradual separation and separability of the regulation of transcription of 5S and larger subunit rRNAs; 2) retention of a transcription unit containing both large and small rRNAs; and 3) clustering of genes for both 5S and 18S-28S rDNAs, with the possible association ...

Ribosomal DNA and the nucleolus at the heart of aging
Trends in Biochemical Sciences, 2022The rRNA genes [ribosomal DNA (rDNA)] are organized in a prominent nuclear compartment, the nucleolus. It is now well established that the nucleolus functions beyond ribosome biosynthesis, regulating several physiological cellular responses. The nucleoli constitute dynamic genomic/nuclear hubs and demonstrate unique inherent characteristics, rendering ...

Nature, 1969
THE amount of DNA complementary to ribosomal RNA (rDNA) has been shown to be constant in several tissues varying in rRNA synthesis1,2. There is, however, a dramatic exception to this in amphibian and insect oocytes3–5, where amplification of the rDNA occurs and results in high rates of rRNA synthesis during oogenesis6.

Circular ribosomal DNA and ribosomal DNA: replication in somatic amphibian cells
Chromosoma, 1975Pulse labelled rDNA from cultured somatic cells of Xenopus laevis was examined by electron microscope autoradiography. The pattern of replication closely resembles that of bulk chromosomal DNA and differs considerably from rDNA synthesis during amplification in the oocyte.

Non-canonical DNA structures in the human ribosomal DNA
Histochemistry and Cell Biology, 2023Non-canonical structures (NCS) refer to the various forms of DNA that differ from the B-conformation described by Watson and Crick. It has been found that these structures are usual components of the genome, actively participating in its essential functions.

Ribosomal DNA as target for the assessment of DNA degradation of human and canine DNA
Legal Medicine, 2021The assessment of DNA amount and DNA integrity can support forensic DNA analysis, in particular of problematic traces such as single telogen hairs where STR typing success is often hampered by low amounts and strong degradation of nuclear DNA. Common strategies consist of quantitative polymerase chain reaction (qPCR)-based analysis of the abundance of ...

Heterogeneity in cucumber ribosomal DNA
Theoretical and Applied Genetics, 1986Restriction and hybridization analysis of cucumber native ribosomal (r) DNA purified from actinomycin-D/CsCl gradients suggested that the repeat units were heterogeneous in both length and sequence. Several full length rDNA repeat units were cloned and five are described which account for all the EcoR I and Xba I fragments present in native DNA. One of
