Recent studies have unveiled disrupted metabolism in the progression of cleft palate (CP), a congenital anomaly characterized by defective fusion of facial structures. Nonetheless, the precise composition of this disrupted metabolism remains elusive, prompting us to identify these components and elucidate primary metabolic irregularities contributing to CP pathogenesis. We established a murine CP model by retinoic acid (RA) treatment and analyzed control and RA-treated embryonic palatal tissues by LC-MS-based proteomic approach. We identified 220 significantly upregulated and 224 significantly downregulated proteins. Gene Ontology (GO) and Kyoto Encyclopedia of Genes and Genomes (KEGG) enrichment analysis revealed that these differentially expressed proteins (DEPs) were involved in translation, ribosome assembly, mitochondrial function, mRNA binding, as well as key metabolic pathways like oxidative phosphorylation (OXPHOS), glycolysis/gluconeogenesis, and amino acid biosynthesis. These findings suggest that dysregulated ribosome-related pathways and disrupted metabolism play a critical role in CP development. Protein-protein interaction analysis using the STRING database revealed a tightly connected network of DEPs. Furthermore, we identified the top 10 hub proteins in CP using the Cytohubba plugin in Cytoscape. These hub proteins, including RPL8, RPS11, ALB, PA2G4, RPL23, RPS6, CCT7, EGFR, HSPD1, and RPS28, are potentially key regulators of CP pathogenesis. In conclusion, our comprehensive proteomic analysis provides insights into the molecular alterations associated with RA-induced CP in Kun Ming mice. These findings suggest potential therapeutic targets and pathways to understand and prevent congenital craniofacial anomalies.
A newborn suffered immediate neonatal respiratory distress because of an obstructive, soft-tissue nasal mass. Clinical examination revealed a cleft palate with a protruding polypoid mass. CT and MRI showed a heterogeneous nasopharyngeal mass and associated intracranial abnormalities - duplication of the hypophysis and hypoplasia of the corpus callosum. Duplication of the hypophysis is a very rare malformation, only 13 cases having been previously described. The suggested pathogenesis is duplication of the prechordal plate and anterior end of the notochord during early embryological development.
New developments in deoxyribonucleic acid (DNA) technology are increasing understanding of the role of genetics in health and disease. This kind of health information requires that perioperative nurses develop new skills and roles that will enhance the quality of genetic health care they provide to patients, particularly with regard to managing genetic information. Perioperative nurses expand their scope of practice to incorporate a genetic focus into health assessment, patient education, and patient support as they assimilate new genetic information into their daily lives. Perioperative nurses familiar with genetic counseling services--and how and when to refer patients for such services--will ensure that all patients have access to the most current and appropriate genetic information with which to make informed health choices.
