RNA Repair: Damage Control
RNA in a cell is subject to many of the same insults as DNA. RNA damage can induce apoptosis and may be exploited for anti-cancer chemotherapy. It is a surprise, however, to learn that cells may repair RNA damage, suggesting a far greater significance of RNA in genotoxic stress.
متن کاملRNA Repair: Damage Control Dispatch
Damage to DNA is a significant issue for all cells, particularly in cancer where DNA repair commonly fails. It is not widely appreciated that many agents that cause damage to DNA, such as radiation and certain cancer chemotherapy drugs, also damage RNA. Given that there is at least as much RNA in a cell as DNA, wherever DNA is damaged by such agents, RNA is surely damaged as well. When the dama...
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 کاملViral AlkB proteins repair RNA damage by oxidative demethylation
Bacterial and mammalian AlkB proteins are iron(II)- and 2-oxoglutarate-dependent dioxygenases that reverse methylation damage, such as 1-methyladenine and 3-methylcytosine, in RNA and DNA. An AlkB-domain is encoded by the genome of numerous single-stranded, plant-infecting RNA viruses, the majority of which belong to the Flexiviridae family. Our phylogenetic analysis of AlkB sequences suggests ...
متن کاملRNA damage in biological conflicts and the diversity of responding RNA repair systems
RNA is targeted in biological conflicts by enzymatic toxins or effectors. A vast diversity of systems which repair or 'heal' this damage has only recently become apparent. Here, we summarize the known effectors, their modes of action, and RNA targets before surveying the diverse systems which counter this damage from a comparative genomics viewpoint. RNA-repair systems show a modular organizati...
