DNA-Repair Capacity in Down\'s Syndrome
Down's syndrome (DS) is the most common chromosomal abnormality in human. Subjects with DS are known to be peridisposed to develop leukemia. The molecular basis of the association between DS and leukemia is unknown. The unscheduled DNA synthesis (UDS) test measure the ability of DNA-repair in mammalian cells after excision of a stretch of DNA containing the region of damage induced by chemical ...
متن کاملFUS-regulated RNA metabolism and DNA damage repair
Cytoplasmic inclusion of RNA binding protein FUS/TLS in neurons and glial cells is a characteristic pathology of a subgroup of amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD). Dysregulation of RNA metabolism caused by FUS cytoplasmic inclusion emerges to be a key event in FUS-associated ALS/FTD pathogenesis. Our recent discovery of a FUS autoregulatory mechanism and its dy...
متن کاملDiversity of Endonuclease V: From DNA Repair to RNA Editing
Deamination of adenine occurs in DNA, RNA, and their precursors via a hydrolytic reaction and a nitrosative reaction. The generated deaminated products are potentially mutagenic because of their structural similarity to natural bases, which in turn leads to erroneous nucleotide pairing and subsequent disruption of cellular metabolism. Incorporation of deaminated precursors into the nucleic acid...
متن کاملRB in DNA repair
The retinoblastoma protein (RB1) has a well-documented role as a key regulator of cell cycle progression by controlling the G1/S phase transition [1]. RB1 has also emerged as a multi-functional protein involved in a wide range of biological processes including transcriptional regulation by recruiting chromatin remodelling enzymes, DNA replication via interaction with DNA polymerase complex comp...
متن کاملOptimality in DNA repair
DNA within cells is subject to damage from various sources. Organisms have evolved a number of mechanisms to repair DNA damage. The activity of repair enzymes carries its own risk, however, because the repair of two nearby lesions may lead to the breakup of DNA and result in cell death. We propose a mathematical theory of the damage and repair process in the important scenario where lesions are...
