(Submitter supplied) Animals develop skin regional specificities to best adapt to their environments. Birds are excellent models in which to study the epigenetic mechanisms that facilitate these adaptions. Patients suffering from SATB2 mutations exhibit multiple defects including ectodermal dysplasia-like changes. The preferential expression of SATB2, a chromatin regulator, in feather-forming compared to scale-forming regions, suggests it functions in regional specification of chicken skin appendages by acting on either differentiation or morphogenesis. more...

(Submitter supplied) Regional specification is critical for skin development, regeneration and evolution. The contribution of epigenetics in this process remains unknown. Here using avian epidermis we find two major strategies regulate β-keratin gene clusters. 1) Over the body, macro-regional specificities (scales, feathers, claws, etc) established by typical enhancers control five sub-clusters located within the epidermal differentiation complex on chromosome 25; 2) Within a feather, micro-regional specificities are orchestrated by temporo-spatial chromatin looping of the feather β-keratin gene cluster on chromosome 27. more...

(Submitter supplied) Feather evolution enabled feathered dinosaurs and early Mesozoic birds to venture into new ecological niches. Studying how feathers and scales are specified provides insight into how a new organ evolves. We use genome-wide analyses to identify feather-associated genes and test their feather-forming ability by expressing them in chicken and alligator scales. Intermediate morphotypes revealed five cardinal morphogenetic events: localized growth zone, follicle invagination, branching, feather keratin differentiation and dermal papilla formation. more...

(Submitter supplied) Epidermal keratinocytes form cornified skin appendages such as scutate scales on the legs of birds. Here, we investigated the molecular pathways of keratinocyte differentiation in chicken scutate scales by single cell transcriptomics. We identified two distinct populations of differentiated keratinocytes. The first type of differentiated keratinocytes is characterized by mRNAs encoding scale-type corneous beta-proteins (CBPs), also known as beta-keratins and cysteine-rich keratins, indicating that these cells form hard scales. more...

(Submitter supplied) Gene activity programmes in different cell types control development and homeostasis of multi-cellular organisms. Spatial genome organization controls gene activity by facilitating or restricting contacts between gene promoters and remote gene enhancers. Functionally related co-regulated genes are often located together in genomes loci. The spatial organization of very large co-regulated gene loci remains poorly understood. more...

(Submitter supplied) Induction of lineage-specific gene programs are strongly influenced by alterations in local chromatin architecture. However, key players that impact this genome reorganization remain largely unknown. Here, we report that removal of special AT-rich binding protein 2 (SATB2), a nuclear protein known to bind matrix attachment regions, is a key event in initiating myogenic differentiation. Deletion of myoblast SATB2 in vitro initiates chromatin remodeling and accelerates differentiation, while in vivo ablation depletes the muscle progenitor pool. more...

(Submitter supplied) Special AT-rich sequencebinding protein 2 (SATB2) is essential for the development of cerebral cortex and key molecular node for the establishment of proper neural circuitry and function. Mutations in SATB2 gene lead to SATB2-associated syndrome (SAS), which is characterized by abnormal development of skeleton and central nervus system. We generated Satb2 knockout mouse model through CRISPR-Cas9 technology and performed RNA-seq and ChIP-seq of embryonic cerebral cortex. more...

(Submitter supplied) Avian beaks show extreme species-specific variability in morphology, though they develop from the same primordial structures. In both humans and birds, cranial neural crest cells are the primary source of mesenchyme for the frontonasal prominence; previous work has shown that these cells contain molecular information that regulate species-specific facial variation. To determine the molecular basis of avian craniofacial patterning, we have gene expression profiled micro-dissected cranial neural crest cells from the frontonasal prominence of three bird species (chickens, quails, and ducks) during embryonic development. more...
