"On useita raportteja ZNF- perheen osallistumisesta diabeteksen kehittymiseen.

Esimerkkinä on GLIS3 (C2H2-tyyppinen transkriptiofaktori, Krüppelin kaltaisen rakenteen omaava ZNF-proteiini), jota ilmenee vahvasti haiman beetasoluissa. GLIS3-geenin mutaatioita on tunnistettu ihmisen neonataalidiabeteksessa ja kongenitaalisessa hypotyreoidismissa (NDH). Ihmisen GLIS3-mutaatio johtaa C-terminaalisesti lyhentyneeseen proteiiniin, mutta ei ole selvitetty, millä tavalla tämä mutaatio johtaa neonataalidiabetekseen. GLIS3 moduloi insuliinin ilmentymistä sekä suoralla että epäsuoralla mekanismilla sitoutumalla INS- promoottoriin tai moduloimalla toisien, beetasoluun rikastuneiden transkriptiofaktoreiden aktiivisuutta kuten MafA, Nkx6-1 ja Pax6:

• MafA https://www.ncbi.nlm.nih.gov/gene/389692 Also known as INSDM; hMafA; RIPE3b1Summary MAFA is a transcription factor that binds RIPE3b, a conserved enhancer element that regulates pancreatic beta cell-specific expression of the insulin gene (INS; MIM 176730) (Olbrot et al., 2002 [PubMed 12011435]).[supplied by OMIM, Mar 2008]

• Nkx6-1 https://www.ncbi.nlm.nih.gov/gene/4825 Also known as NKX6A; NKX6.1 Summary In the pancreas, NKX6.1 is required for the development of beta cells and is a potent bifunctional transcription regulator that binds to AT-rich sequences within the promoter region of target genes Iype et al.

• Pax6. https://www.ncbi.nlm.nih.gov/gene/5080 Also known as AN; AN2; FVH1; MGDA; WAGR; ASGD5; D11S812E Summary This gene encodes paired box protein Pax-6, one of many human homologs of the Drosophila melanogaster gene prd. In addition to a conserved paired box domain, a hallmark feature of this gene family, the encoded protein also contains a homeobox domain. Both domains are known to bind DNA and function as regulators of gene transcription. Activity of this protein is key in the development of neural tissues, particularly the eye. This gene is regulated by multiple enhancers located up to hundreds of kilobases distant from this locus. Mutations in this gene or in the enhancer regions can cause ocular disorders such as aniridia and Peter's anomaly. Use of alternate promoters and alternative splicing results in multiple transcript variants encoding different isoforms. Interestingly, inclusion of a particular alternate coding exon has been shown to increase the length of the paired box domain and alter its DNA binding specificity. Consequently, isoforms that carry the shorter paired box domain regulate a different set of genes compared to the isoforms carrying the longer paired box domain.

"Muutamia vuosia siten on saatu kehitettyä GLIS3-vajeinen hiirimalli (GLIS3-/-) ja se ilmentää korkeita verensokeripitoisuuksia, haimadefektejä ja keskoiskuolleisuutta. Nämä fenotyypit muistuttavat ihmisen neonataalidiabetesta, jota aiheutuu GLS3 mutaatioista. Tämä hiirimalli voisi olla hyvin hyödyllinen tutkittaessa terapeuttisia sovelluksia ihmisen diabetekseen. On alettu tunnistaa GLS3-mutaatioista johtuvia uusia kliinisiä manifestaatioita neonataalidiabetesta potevilla ihmisillä: on tunnistettu luustodeformaatioihin ja murtumiin assosioituvaa osteopeniaa, molemminpuolista sensorineuraalia kuuroutta ja exogeenisen haiman vikatoimintaa. Näitä kliinisiä piirteitä ei ole aiemmin kuvattu, mikä osoittaa GLIS3-mutaatiofenotyypin suurta vaihtelevaisuutta ottaen huomioon että erilaiset geneettiset mutaatiot johtavat kudosspesifisen Glis3 mRNA:n ilmenemiseen”.

Also known as NDH; ZNF515 .Summary This gene is a member of the GLI-similar zinc finger protein family and encodes a nuclear protein with five C2H2-type zinc finger domains. This protein functions as both a repressor and activator of transcription and is specifically involved in the development of pancreatic beta cells, the thyroid, eye, liver and kidney. Mutations in this gene have been associated with neonatal diabetes and congenital hypothyroidism (NDH). Alternatively spliced variants that encode different protein isoforms have been described but the full-length nature of only two have been determined.

   GLIS3 mutations are associated with type 1, type 2, and neonatal diabetes, reflecting a key function for this gene in pancreatic β-cell biology. Previous attempts to recapitulate disease-relevant phenotypes in GLIS3^-/- β-like cells have been unsuccessful. Here, we develop a "minimal component" protocol to generate late-stage pancreatic progenitors (PP2) that differentiate to mono-hormonal glucose-responding β-like (PP2-β) cells. Using this differentiation platform, we discover that GLIS3^-/- hESCs show impaired differentiation, with significant death of PP2 and PP2-β cells, without impacting the total endocrine pool. Furthermore, we perform a high-content chemical screen and identify a drug candidate that rescues mutant GLIS3-associated β-cell death both in vitro and in vivo. Finally, we discovered that loss of GLIS3 causes β-cell death, by activating the TGFβ pathway. This study establishes an optimized directed differentiation protocol for modeling human β-cell disease and identifies a drug candidate for treating a broad range of GLIS3-associated diabetic patients.
