288 Traceless, homology-directed repair-mediated gene editing for junctional epidermolysis bullosa

نویسندگان

چکیده

In this study, we used combinations of Cas9 or nickase (Cas9n) and single gRNA (sgRNA) ribonucleoprotein (RNP) complexes with single-stranded oligonucleotides (ssODN) to induce homology-directed repair (HDR) in junctional epidermolysis bullosa (JEB) keratinocytes a pathogenic mutation exon 52 COL17A1. To assess the correction efficiency, treated patient were then analysed via next generation sequencing (NGS), Western Blot, sqRT-PCR, Flow cytometry immunofluorescence stainings cell monolayers as well 3D skin equivalents. analysis indicated efficiencies ∼60 %, while NGS revealed precise installation desired edit almost ∼38 % cells. Furthermore, equivalents generated from these accurate deposition C17 along dermal-epidermal basement membrane zone (BMZ). Taken together, our data suggest that high nature HDR-mediated edits make approach clinically relevant for monogenetic diseases such JEB.

Junctional epidermolysis bullosa.

Epidermolysis bullosa (EB) encompasses a heterogeneous group of genodermatoses, characterized by fragility and blistering of the skin, often associated with extracutaneous manifestations. The level of vesiculation within the skin defines 3 major subtypes of EB: EB simplex, junctional EB, and dystrophic EB. We present the case of a male neonate of 36 weeks of gestation, who was born with a few b...

Junctional and Dystrophic Epidermolysis Bullosa

Epidermolysis bullosa (EB) is a congenital genodermatosis, which affects mainly skin and occasionally other organs [1]. Lifelong blistering and erosion of the skin and mucous membrane, caused by mechanical trauma, threaten EB patients [1]. The most common cause of death is metastasizing squamous cell carcinoma [2]. EB is subdivided into mainly three categories by the location of tissue separati...

Herlitz Junctional Epidermolysis Bullosa Keratinocytes Display

Previous studies have correlated the Herlitz junctional epidermolysis bullosa (H-JEB) to an altered expression of the basement membrane component nicein/kalinin. This heterotrimeric glycoprotein appears to be present in H-JEB tissues in an abnormal form, because a number of antibodies specific to the protein either do not react with or weakly stain the epidermal basement membranes of most of th...

Junctional Epidermolysis Bullosa (Non-Herlitz Type).

Junctional epidermolysis bullosa (JEB) is a recessively inherited skin blistering disease and is caused due to abnormalities in proteins that hold layers of the skin. Herlitz JEB is the severe form and non-Herlitz JEB is the milder form. This report describes a case of congenitally affected male child aged 5 years, with skin blistering. He has mitten-like hands and soft skin blistering on hands...
