Present status and expectation of aristaless-related homeobox (ARX) in endocrine pancreas

Abstract: The aristaless-related homeobox (ARX) gene has become one of most frequently mutated genes which is closely linked with development of the vertebrate central nervous system; however, the molecular and clinical bases of its function in the proliferation and differentiation of the endocrine pancreas have not, to date, been systematically characterized. ARX is considered as a regulator which determines endocrine cell fate and a bio-marker of the pancreatic a-cell. Disruption and mutation of ARX are found to lead … Show more

“…The Arista-less homeobox-containing transcription factor ARX is restricted to α cells, pancreatic polypeptideproducing cells (PP cells), and ghrelin-producing ε cells in the islet (Mastracci et al 2011, Wilcox et al 2013, DiGruccio et al 2016. Considered the 'master regulator' of α cell identity, the ARX transcription factor has been shown to be necessary for the development and maintenance of α cells in mice and humans as well as being sufficient to convert β cells into α cells (Collombat et al 2003, Itoh et al 2010, Mastracci et al 2011, Courtney et al 2013, Wilcox et al 2013, Xu & Xu 2019. The loss of Arx in α cells simultaneously causes decreased glucagon expression and increased insulin and somatostatin expression (Collombat et al 2007, Mastracci et al 2011, Wilcox et al 2013, Chakravarthy et al 2017Fig.…”

“…Варто відзначити, що в гризунів експресія Nkx2.2 була виявлена в MPC до розвитку ендокринних попередників, тоді як у людей Nkx2.2 не виявлено в MPC фетальної ПШЗ і фактор починає експресуватися після ендокринної індукції [43]. У сукупності ці результати свідчать про видову різницю в експресії та функції NKX6.1 під час розвитку ПШЗ [50].…”

“…Під час проліферації та регенерації -клітин регуляторна область ARX підтримується в статусі метилювання, індукованого DNMT1. Метильована область локусу ARX у -клітинах зв'язується метил-зв'язуючим білком 2 (methyl CpG binding protein 2, MeCP2), який рекрутує гістонову метилтрансферазу (histone methyltransferase, HMT) білкову аргінін метилтрансферазу 6 (protein arginine methyltransferase 6, PRMT6), яка опосередковує метилювання H3R2, що призводить до репресії ARX [50].…”
