要約等
<p>Amyotrophic lateral sclerosis (ALS) and frontotemporal dementia (FTD) are neurodegenerative diseases with a progressive and fatal course. They are often comorbid and share the same molecular spectrum. Their key pathological features are the formation of the aggregation of TDP-43, an RNA-binding protein, in the cytoplasm and its depletion from the nucleus in the central nervous system. In the nucleus, TDP-43 regulates several aspects of RNA metabolism, ranging from RNA transcription and alternative splicing to RNA transport. Suppressing the aberrant splicing events during RNA processing is one of the significant functions of TDP-43. This function is impaired when TDP-43 becomes depleted from the nucleus. Several critical cryptic splicing targets of TDP-43 have recently emerged, such as <i>STMN2</i>, <i>UNC13A</i>, and others. <i>UNC13A</i> is an important ALS/FTD risk gene, and the genetic variations, single nucleotide polymorphisms, cause disease via the increased susceptibility for cryptic exon inclusion under the TDP-43 dysfunction. Moreover, TDP-43 has an autoregulatory mechanism that regulates the splicing of its mRNA (<i>TARDBP</i> mRNA) in the healthy state. This study provides recent findings on the splicing regulatory function of TDP-43 and discusses the prospects of using these aberrant splicing events as efficient biomarkers.</p>
