MiRNA-470-5p suppresses epithelial-mesenchymal transition of embryonic palatal shelf epithelial cells by targeting during palatogenesis.

MicroRNAs (miRNAs) have been identified as crucial modulators of gene expression and to play a role in palatogenesis. The aim of this study was to explore the potential role and regulatory mechanisms of miRNAs during palatogenesis. RNA-sequencing was performed to compare the RNA expression profiles of mouse embryonic palatal shelf (MEPS) tissue between an all-trans retinoic acid (ATRA)-induced group and control group, followed by reverse transcription-quantitative polymerase chain reaction for validation, demonstrating upregulated expression of miRNA-470-5p and downregulated expression of in the ATRA-induced group.

LncRNA-NONMMUT100923.1 regulates mouse embryonic palatal shelf adhesion by sponging miR-200a-3p to modulate medial epithelial cell desmosome junction during palatogenesis.

Cleft palate (CP) is a common neonatal craniofacial defect caused by the adhesion and fusion dysfunction of bilateral embryonic palatal shelf structures. Long non-coding RNA (lncRNA) is involved in CP formation with regulatory mechanism unknown. In this study, all-trans retinoic acid (ATRA) was used to induced cleft palate in embryonic mice as model group.

Exogenous fibrolytic enzymes promoted energy and nitrogen utilization and decreased CH4 emission per unit dry matter intake of tan sheep grazed a typical steppe by enhancing nutrient digestibility on China loess plateau.

Exogenous fibrolytic enzyme (EFE) products in ruminant nutrition may be an important alternative to meet the increased demands for animal products in the future with reduced environmental impacts. This study aimed to evaluate the dose-response of EFE supplementation on the nutrient digestibility, nitrogen and energy utilization, and methane (CH4) emissions of Tan sheep grazed in summer and winter. A total of 20 Tan wether sheep with an initial body weight of 23.
