The recent identification of molecular cues involved in the generation of the cortical area map, such as the patterning molecule FGF8 and transcription factors such as Emx2, represents an important breakthrough. In this issue of Neuron, Hamasaki et al. use a genetic approach to explore how these signals interact and propose that Emx2 plays a direct, largely FGF8-independent role in the control ...
Development of the vertebrate eye is dependent on multiple tissue interactions and distinct sets of transcription factors and signalling molecules. The latter are thought to be FGF8 and BMP4, proteins secreted from the neural plate to induce lens formation in the overlying ectoderm. Here we show that the Pbx transcription factor plays a crucial role in this process, as it is required for FGF8 e...
The p63 transcription factor, homolog to the p53 tumor suppressor gene, plays a crucial role in epidermal and limb development, as its mutations are associated to human congenital syndromes characterized by skin, craniofacial and limb defects. While limb and skin-specific p63 transcriptional targets are being discovered, little is known of the post-translation modifications controlling ΔNp63α f...
Objectives: Bone immune disorders are major contributors to osteoporosis development. This study aims identify potential diagnostic markers and molecular targets for treatment from an immunological perspective. Method: We downloaded dataset GSE56116 the Gene Expression Omnibus database, identified differentially expressed genes (DEGs) between normal groups. Subsequently, immune-related (DEIRGs)...
The anterior neural ridge (ANR), and the isthmic organiser (IsO) represent two signalling centres possessing organising properties necessary for forebrain (ANR) as well as midbrain and rostral hindbrain (IsO) development. An important mediator of ANR and IsO organising property is the signalling molecule FGF8. Previous work has indicated that correct positioning of the IsO and Fgf8 expression i...
In vertebrates, the common expression border of two homeobox genes, Otx2 and Gbx2, demarcates the prospective midbrain-hindbrain border (MHB) in the neural plate at the end of gastrulation. The presence of a compartment boundary at the MHB has been demonstrated, but the mechanism and timing of its formation remain unclear. We show by genetic inducible fate mapping using a Gbx2(CreER) knock-in m...
CONTEXT Kallmann syndrome (KS), combined pituitary hormone deficiency (CPHD), and septo-optic dysplasia (SOD) all result from development defects of the anterior midline in the human forebrain. OBJECTIVE The objective of the study was to investigate whether KS, CPHD, and SOD have shared genetic origins. DESIGN AND PARTICIPANTS A total of 103 patients with either CPHD (n = 35) or SOD (n = 68...
Axial eye patterning determines the positional code of retinal ganglion cells (RGCs), which is crucial for their topographic projection to the midbrain. Several asymmetrically expressed determinants of retinal patterning are known, but it is unclear how axial polarity is first established. We find that Fgf signals, including Fgf8, determine retinal patterning along the nasotemporal (NT) axis du...
In vertebrate limbs that lack webbing, the embryonic interdigit region is removed by programmed cell death (PCD). Established models suggest that bone morphogenetic proteins (BMPs) directly trigger such PCD, although no direct genetic evidence exists for this. Alternatively, BMPs might indirectly affect PCD by regulating fibroblast growth factors (FGFs), which act as cell survival factors. Here...
The brain vesicles that are formed at an early stage of neural development are the fundamentals of the brain plan. Heterotopic transplantation revealed that the diencephalon could change its fate when juxtaposed to the isthmus (mes-metencephalic boundary), which indicated that the isthmus functions as an organizer for the mesencephalon and metencephalon. Fgf8 is identified as an isthmus organiz...
