In recent years, long noncoding RNAs (lncRNAs) have garnered increasing attention as vital components in biological regulation. At Creative Biolabs, we reveal the potential roles of lncRNAs by precisely targeting those that exhibit differential expression under specific conditions.
What Are LncRNAs?
LncRNAs constitute a unique category of RNA molecules, characterized by their extended length of exceeding 200 nucleotides. Rather than encoding proteins, lncRNAs play pivotal roles in a series of cellular processes. For instance, lncRNAs facilitate the regulation of gene transcription by enlisting chromatin-modifying enzymes. Furthermore, they are capable of forming stable, higher-order structures, thereby engaging in diverse processes such as protein synthesis, cellular growth, and cellular differentiation.
