Fanconi anemia (FA) is characterized by chromosome fragility, bone marrow failure (BMF) and predisposition to cancer. As reverse genetic mosaicism has been described as “natural gene therapy” in patients with FA, we sought evaluate the clinical course of a cohort FA mosaic followed at referral centers Spain over 30-year period. This includes majority T cells without chromosomal aberrations DEB-...
Hematopoietic stem and progenitor cells (HSPCs) give rise to all of the cells that make up the hematopoietic system in the human body, making their stability and resilience especially important. Damage to these cells can severely impact cell development and has the potential to cause diseases, such as leukemia. Leukemia-causing chromosomal rearrangements have largely been studied in the context...
Spontaneous DNA breaks instigate genomic changes that fuel cancer and evolution, yet direct quantification of double-strand breaks (DSBs) has been limited. Predominant sources of spontaneous DSBs remain elusive. We report synthetic technology for quantifying DSBs using fluorescent-protein fusions of double-strand DNA end-binding protein, Gam of bacteriophage Mu. In Escherichia coli GamGFP forms...
Specific chromosome changes are consistently observed in numerous types of neoplasms. These chromosome changes are generally seen only in malignant cells and are not present in somatic cells. Associations of an increased incidence of cancer following exposure to certain chromosome breakage agents, in chromosome instability syndromes, and in patients with gene or constitutional chromosomal imbal...
