Transcriptome Sequencing

RNA sequencing (RNA-seq) is a groundbreaking method for understanding cellular functions and gene regulation mechanisms. This technique provides unique insights into the transcriptional architecture of cells, enabling precise profiling of gene expression. Supported by Next Generation Sequencing (NGS) technology, RNA-seq identifies dynamic variations within the transcriptome and allows for the analysis of cellular responses under different conditions. In this approach, single-stranded messenger RNAs (mRNAs) are selectively captured or enriched and then converted into complementary DNA (cDNA) for library preparation.

Long Non-Coding RNAs (lncRNAs) are a class of non-coding RNAs longer than 200 nucleotides (nt), constituting a significant portion of the eukaryotic transcriptome. This group includes various subtypes such as intergenic lncRNAs (lincRNAs), intronic, antisense, sense, and bidirectional lncRNAs. lncRNAs exert diverse effects on cellular functions through transcriptional regulation, post-transcriptional modifications, and epigenetic mechanisms. They play critical roles particularly in gene expression control and cell differentiation. lncRNA sequencing (lncRNA-seq) is a powerful Next Generation Sequencing (NGS) method widely used to explore the functional roles of lncRNAs in various human diseases, especially cancer and neurological disorders.

Small RNAs (sRNAs) are short, typically non-coding RNA molecules that play essential roles in post-transcriptional regulation of gene expression and gene silencing at the cellular level. Among them, microRNAs (miRNAs) are usually 18–40 nucleotides in length and have critical regulatory functions. Small RNA sequencing (sRNA-seq) enables the sensitive and detailed analysis of these small RNA species. This method is particularly valuable for microRNA profiling, the discovery of disease biomarkers, understanding developmental processes, and monitoring cellular responses under various conditions.

Circular RNAs (circRNAs) are a class of non-coding RNAs (ncRNAs) characterized by covalently closed loop structures lacking 5' caps and 3' poly(A) tails. This unique circular configuration confers high resistance to exonuclease degradation, rendering circRNAs highly stable molecules. Such structural stability facilitates their efficient analysis during library preparation processes. circRNAs play important roles in genetic regulation, post-transcriptional processes, and serve as potential biomarkers in various biological studies.
