(1) Background: Colorectal cancer (CRC) is the third most common cancer in human and the fourth leading cause of adult man’s death. Murine tumor cell lines have been established as a model system for CRC, but their cytogenetic properties have so far been only poorly understood.
(2) Methods: The two [...]
Histone modifications play an important role in the control of all DNA-based processes by altering the structure and function of chromatin. An O-linked N-acetylglucosamine (O-GlcNAc) modification is a type of post-translational modification of proteins, and gets attached to serine (Ser)/threonine (T [...]
Background: Small supernumerary marker chromosomes (sSMC) are structurally abnormal chromosomes, and their characterization exclusively by banding cytogenetics is almost impossible. Multicolor fluorescence in situ hybridization approaches for their characterization are effective but expensive and ti [...]
he publication of the double helix DNA structure in 1953  was the kick-off of numerous efforts to understand and unravel the complexity of the human genome. It took 50 years until the human genome project, based on Sanger sequencing, was completed in 2003 . This was followed by what may be con [...]
Background: Small supernumerary marker chromosomes (sSMC) are rare cytogenetic findings in general, but especially in Turner syndrome so called sSMCT in a karyotype 46,X,mar are even more scarce. According to the literature sSMCT are derived from one of the Y-chromosome in ~70% of the cases. Thus, t [...]
Immunoglobin A Nephropathy (IgAN) is the most common primary glomerulonephritis worldwide. Its development is characterized by the deposition of immune complexes that consist of abnormally galactozylated IgA1 molecules and IgG or IgA autoantibodies in the mesangium and the subsequent induction of re [...]
Uniparental disomy (UPD), the inheritance of both homologues of a chromosome from only one parent, has been reported for nearly all human chromosomes. Depending on its mode of formation and time of occurrence, UPD can be present in all cells of an organism, or restricted to some cell lines as a mosa [...]
Wilson Disease is a monogenetic disorder of copper metabolism affecting the ATP7B gene. Treatment is lifelong and focuses on removal of copper to arrest disease progression and improve the clinical manifestations of copper toxicity. Currently the only cure is replacement of ATP7B in hepatocytes by l [...]
Background: With their varied pharmacophores, natural products are interesting tools to open the drug discovery pipeline. Several plant secondary metabolites belong to our diet and have conflictual documented epigenetic activities which need clarification.
Methods: Seventy-one different natural pro [...]
Runs of homozygosity (ROH) are uninterrupted continuous regions within the genome exhibiting allelic homozygosity (identical alleles are inherited from each parent). Genome-wide analyses consistently evidence that megabase-scale ROH are ubiquitous in humans reflecting individual demographic history. [...]
