Piwi-interacting RNA sequencing (piRNA-seq) is a next-generation sequencing (NGS)-based method to comprehensively capture, sequence and analyze piRNA sequences (26-32nt) in animal cells. These small fragments function primarily by interacting with PIWI (P-element-induced wimpy testis) family proteins to form RNA-protein complexes. Our piRNA-seq service is dedicated to detecting and analyzing all piRNAs in a sample, providing a powerful tool for piRNA screening and research.
The piRNAs are the largest class of single-stranded, small non-coding RNAs of about 26-32 nucleotides. Two types of piRNAs have been identified based on their genomic origins: repetitive sequence-derived piRNAs and non-repetitive sequence-derived piRNAs. The piRNAs are commonly expressed only in totipotent animal cells, such as germ cells, tumor cells and stem cells in a tissue-specific manner. piRNA performs biological functions by combining with PIWI subfamily proteins, which are mainly expressed in the germline, to form piRNA complexes (piRC) and are involved in epigenetic, transcriptional and post-transcriptional silencing of transposons and other genetic elements, maintaining the functions of germ cells and stem cells, and regulating mRNA translation and stability. In addition, evidences are arising that piRNA is abnormally expressed in multiple cancers, which suggest piRNAs may be involved in the occurence and development of tumors. piRNA sequencing (piRNA-seq) is a sequencing technology specifically designed to capture piRNA from animal cells, allowing the detection of piRNAs isoforms and novel piRNAs. piRNA-seq provides insight into transposon silencing, germline development, spermatogenesis, and how they maintain genomic integrity. In clinical research, especially cancer research, piRNA-seq can be used for elucidating mechanisms underlying diseases, biomarker screening, and development of targeted therapies.
