Abstract
Defective tissue fusion during mammalian embryogenesis results in congenital anomalies, such as exencephaly, spina bifida and cleft lip and/or palate. The highly conserved transcription factor grainyhead-like 2 (Grhl2) is a crucial regulator of tissue fusion, with mouse models lacking GRHL2 function presenting with a fully penetrant open cranial neural tube, facial and abdominal clefting (abdominoschisis), and an open posterior neuropore. Here, we show that GRHL2 interacts with the soluble morphogen protein and bone morphogenetic protein (BMP) inhibitor noggin (NOG) to impact tissue fusion during development. The maxillary prominence epithelium in embryos lacking Grhl2 shows substantial morphological abnormalities and significant upregulation of NOG expression, together with aberrantly distributed pSMAD5-positive cells within the neural crest cell-derived maxillary prominence mesenchyme, indicative of disrupted BMP signalling. Reducing this elevated NOG expression (by generating Grhl2-/-;Nog+/- embryos) results in delayed embryonic lethality, partial tissue fusion rescue, and restoration of tissue form within the craniofacial epithelia. These data suggest that aberrant epithelial maintenance, partially regulated by noggin-mediated regulation of BMP-SMAD pathways, may underpin tissue fusion defects in Grhl2-/- mice.

Abstract
Defects in migration and invasion caused by dysregulation of trophoblast epithelial-mesenchymal transformation (EMT) are one of the key factors in the pathogenesis of preeclampsia (PE). RNA-binding motif protein 25 (RBM25) is an RNA-binding protein involved in a variety of cellular processes, including cell proliferation, apoptosis, cell migration and invasion, and EMT. However, the expression and function of RBM25 in placental of PE remain unclear. In this study, we reveal that the expression of RBM25 is significantly elevated in PE placental tissue. RBM25 depletion and over-expression in trophoblast cells increase and decrease, respectively, cell migration and invasion by regulating EMT marker E-cadherin and Vimentin expression. Mechanistically, Grhl2 is involved in RBM25-regulated trophoblast cell migration, invasion, and EMT through RBM25-facilitated mRNA stabilization. Furthermore, the upregulation of Grhl2 enhances the expression of RBM25 through transcription and forms a positive feedback regulation in the progression of PE. These findings suggest that upregulation of RBM25 induces dysregulation of trophoblast EMT by enhancing positive feedback regulation of Grhl2 and RBM25, leading to defects in cell migration and invasion. Targeting this newly identified regulatory axis may provide benefits in the prevention and treatment of PE.

Abstract
Cleft lip and palate are common birth defects resulting from failure of the facial processes to fuse during development. The mammalian grainyhead-like (Grhl1-3) genes play key roles in a number of tissue fusion processes including neurulation, epidermal wound healing and eyelid fusion. One family member, Grhl2, is expressed in the epithelial lining of the first pharyngeal arch in mice at embryonic day (E)10.5, prompting analysis of the role of this factor in palatogenesis. Grhl2-null mice die at E11.5 with neural tube defects and a cleft face phenotype, precluding analysis of palatal fusion at a later stage of development. However, in the first pharyngeal arch of Grhl2-null embryos, dysregulation of transcription factors that drive epithelial-mesenchymal transition (EMT) occurs. The aberrant expression of these genes is associated with a shift in RNA-splicing patterns that favours the generation of mesenchymal isoforms of numerous regulators. Driving the EMT perturbation is loss of expression of the EMT-suppressing transcription factors Ovol1 and Ovol2, which are direct GRHL2 targets. The expression of the miR-200 family of microRNAs, also GRHL2 targets, is similarly reduced, resulting in a 56-fold upregulation of Zeb1 expression, a major driver of mesenchymal cellular identity. The critical role of GRHL2 in mediating cleft palate in Zeb1−/− mice is evident, with rescue of both palatal and facial fusion seen in Grhl2−/−;Zeb1−/− embryos. These findings highlight the delicate balance between GRHL2/ZEB1 and epithelial/mesenchymal cellular identity that is essential for normal closure of the palate and face. Perturbation of this pathway may underlie cleft palate in some patients. Summary: Epithelial transcription factor GRHL2 is required for face closure while mesenchymal transcription factor ZEB1 is required for palate closure. Surprisingly, animals lacking both factors close their face and secondary palate.

Abstract
Dysfunctions of epithelial-mesenchymal transition (EMT)-regulated cell migration and invasion have been involved in the pathogenesis of pre-eclampsia (PE). However, the role of circRNAs in EMT of PE has not been widely investigated. In this study, we identified that circTNRC18 was upregulated in PE placentas compared with normal pregnancy placentas. Moreover, circTNRC18 negatively regulated trophoblast cell migration and EMT. Overexpression of circTNRC18 reduced while depletion of circTNRC18 enhanced trophoblast cell migration and EMT. Mechanistically, circTNRC18 sponged miR-762 contributed to inhibit miR-762 activity and elevated EMT-related transcriptional factor Grhl2 protein level. miR-762 expression was lower in PE placentas and played a promoting role in trophoblast cell migration and EMT. In contrast, Grhl2 was highly expressed in PE placentas. Furthermore, we confirmed that upregulation of Grhl2 by circ-TNRC18-induced inhibition of miR-762 led to trophoblast cell migration and EMT. In conclusions, circTNRC18/miR-762/Grhl2 axis plays a key role in trophoblast cell migration and EMT. circTNRC18/miR-762/Grhl2 axis may be a potential therapeutic target in PE.

Abstract
Development of the salivary gland is characterized by extensive branching morphogenesis and lumen formation, the latter of which is closely associated with differentiation into acinar and ductal cells. Although various molecules, including signaling and cell adhesion molecules, have been implicated in salivary gland development, transcription factors (TFs) regulating the expression of those molecules and morphological development of the gland are largely unknown. Here we show that knockdown of the epithelial TF, Grainyhead-like 2 (Grhl2), with siRNA in developing mouse submandibular salivary gland (SMG) cultured ex vivo resulted in retardation of epithelial development. This retardation was concomitant with suppression of gene expression for the cell adhesion molecules, such as E-cadherin and the extracellular protease inhibitor SPINT1, and with the disorganized deposition of the basal lamina protein laminin. ChIP-PCR demonstrated the binding of Grhl2 protein to the Spint1 gene in the SMG. Notably, addition of recombinant SPINT1 protein in cultured SMG overcame the suppressive effects of Grhl2 siRNA on epithelial development and laminin deposition. These findings show that Grhl2 regulation of SPINT1 expression controls salivary gland development.

Abstract
BACKGROUND Pituitary stem/progenitor cells give rise to all of the endocrine cell types within the pituitary gland and are necessary for both development and gland homeostasis. Recent studies have identified several key factors that characterize the progenitor cell population. However, little is known about the factors that regulate progenitor cell differentiation and maintenance. Therefore, it is crucial to identify novel factors that help elucidate mechanisms of progenitor cell function in the developing pituitary. Our studies are the first to characterize the expression of Grainyhead-like 2 (GRHL2), a transcription factor known to regulate progenitor cell plasticity, in the developing pituitary. RESULTS Our studies show GRHL2 expression is highest in the embryonic and early postnatal pituitary and is localized in pituitary progenitor cells. We demonstrate GRHL2 expression is changed in Notch2 cKO and Prop1df/df mice, mouse models that display progenitor cell number defects. In addition, our studies indicate a potential relationship between Notch signaling and GRHL2 expression in the developing pituitary. CONCLUSIONS Taken together, our results indicate GRHL2 as a novel progenitor cell maker in the developing pituitary that may contribute to progenitor cell function and maintenance.

Abstract
The transcription factor grainyhead-like 2 (GRHL2) is expressed in non-neural ectoderm (NNE) and Grhl2 loss results in fully penetrant cranial neural tube defects (NTDs) in mice. GRHL2 activates expression of several epithelial genes; however, additional molecular targets and functional processes regulated by GRHL2 in the NNE remain to be determined, as well as the underlying cause of the NTDs in Grhl2 mutants. Here, we find that Grhl2 loss results in abnormal mesenchymal phenotypes in the NNE, including aberrant vimentin expression and increased cellular dynamics that affects the NNE and neural crest cells. The resulting loss of NNE integrity contributes to an inability of the cranial neural folds to move toward the midline and results in NTD. Further, we identified Esrp1, Sostdc1, Fermt1, Tmprss2 and Lamc2 as novel NNE-expressed genes that are downregulated in Grhl2 mutants. Our in vitro assays show that they act as suppressors of the epithelial-to-mesenchymal transition (EMT). Thus, GRHL2 promotes the epithelial nature of the NNE during the dynamic events of neural tube formation by both activating key epithelial genes and actively suppressing EMT through novel downstream EMT suppressors.
