piRNA are unique small non-coding RNAs, consisting of 26 to 31 nucleotides, that interact closely with Piwi proteins. They predominantly exist in the germ and stem cells of animals and are vital for these cells' growth and preservation. Their structure includes a 5' end with single phosphate uracil and a 3' end with 2'-O-methylation, showcasing specific expression patterns in tissues. Biologically, piRNA play essential roles in gene silencing, the upkeep of germline and stem cell functions, as well as the regulation of protein synthesis and mRNA stability, thus being pivotal in maintaining genome stability and aiding in cell differentiation.
piRNAs are small RNA molecules that play a key role in silencing genes within eukaryotic cells, especially crucial in inhibiting transposons.
piRNAs, through their association with Piwi proteins, can locate and dismantle transposon RNAs, preventing the instability these elements might introduce into the genome.
They contribute to changes in epigenetics by influencing the patterns of DNA methylation and the modification of histones.
By attaching to repetitive DNA sequences, piRNAs help preserve the structural consistency of the genome.
Solid phase synthesis technology is used for piRNA preparation by sequentially constructing the nucleotide chain on a solid support for efficient and accurate synthesis. Initially, the first nucleotide is attached via its 3' end to the solid support, securing it for subsequent reactions. Then, deprotection and coupling reactions are performed sequentially, using activators to add new nucleotides to the 5' end of the growing chain, maintaining precise chemical control to ensure sequence integrity. After completing the assembly of all nucleotides, protective groups are removed, and the piRNA is cleaved from the support and purified by HPLC to remove impurities, resulting in high-quality piRNA for research and application.

Results:
In studies on P. rockii fucata, researchers have explored the roles of piRNA beyond its known function of transposon suppression in animals. By using a specialized oligonucleotide (LNA-antagonist) to inhibit a specific piRNA, piRNA0001, they observed significant changes in the expression of numerous genes. Analysis predicted that piRNA0001 interacts with various genes, with several showing altered expression levels-some increased and others decreased. Furthermore, bioinformatics revealed that piRNA populations engage in the ping-pong cycle in a manner specific to tissue type.
