Summary
MicroRNAs (miRNAs) are crucial for palate development. Dysregulation of these small RNAs can lead to cleft palate, the most common congenital craniofacial defect.
Area of Science:
- Developmental Biology
- Genetics
- Molecular Biology
Background:
- Palatogenesis involves complex gene regulation.
- Cleft palate is a common congenital craniofacial defect.
- MicroRNAs (miRNAs) are key regulators of gene expression.
Purpose of the Study:
- To review molecular mechanisms of palatogenesis involving miRNAs.
- To discuss the role of miRNA dysregulation in cleft palate.
Main Methods:
- Literature review of recent research in zebrafish and mice.
- Analysis of molecular mechanisms of miRNA involvement in palatogenesis.
Main Results:
- miRNAs fine-tune gene regulatory networks during palatogenesis.
- Specific miRNAs are identified as critical for normal palate formation.
- Disruption of miRNA function is linked to cleft palate development.
Conclusions:
- miRNAs are essential regulators of palatogenesis.
- miRNA dysregulation is an etiological factor in cleft palate.
- Further research into miRNA-mediated mechanisms is warranted.

2.2K
The primary cilium, made up of microtubules, acts as antennae on the cell surfaces for relaying external stimuli into the cells. These fine hair-like structures are present, generally one per cell. These are non-motile cilia in a 9+0 microtubules arrangement, where the central pair of microtubules are absent. The primary cilia arise from the basal body embedded in the cell membrane. Intraflagellar transport (IFT) carries requisite proteins from the cytoplasm to the cilium because the primary...

4.2K
MicroRNA (miRNA) are short, regulatory RNA transcribed from introns (non-coding regions of a gene) or intergenic regions (stretches of DNA present between genes). Several processing steps are required to form biologically active, mature miRNA. The initial transcript, called primary miRNA (pri-mRNA), base-pairs with itself, forming a stem-loop structure. Within the nucleus, an endonuclease enzyme, called Drosha, shortens the stem-loop structure into hairpin-shaped pre-miRNA. After the pre-miRNA...
