shRNA necklace H | sterling silver Small hairpin RNA folds back on itself into a tight loop. When delivered by viral vectors into cells, it is processed by Dicer into siRNA and loaded into RISC, silencing target genes on demand. It is the molecular tool that made functional genomics systematic and real. The Science Behind shRNA Short hairpin RNA (shRNA) is a synthetic RNA structure containing a loop that can be processed by endogenous RNA machinery. Delivered via viral vectors (lentiviral, adenoviral), shRNAs are cleaved by Drosha and Dicer into siRNA duplexes, which are loaded into the RISC complex to direct mRNA cleavage. Unlike transient siRNA transfection, shRNA-based silencing is stable and heritable, enabling long-term gene knockdown in cell lines and animal models. Genome-scale shRNA libraries enabled the first large-scale functional screens in mammalian cells, revealing genes essential for cell survival and disease progression. Who Will Recognise It molecular biologists using RNA interference in their work researchers who have run genome-scale shRNA screens RNA biologists and functional genomics specialists anyone working in gene silencing or therapeutic RNAi Explore Related Cellular Biology Jewelry shRNA necklace H | gold vermeil shRNA necklace V | silver MicroRNA necklace | silver FAQ Who wears the shRNA necklace? Molecular biologists and geneticists whose work relies on RNA interference. If you have designed an shRNA, transfected cells with it, or run a genome-scale shRNA screen, this structure is instantly recognizable. What makes shRNA different from siRNA? siRNA is transient (delivered as short double-stranded RNA, degraded after several rounds of silencing). shRNA is stable (expressed from a vector, processed by cellular enzymes, heritable through cell divisions). For long-term, stable gene knockdown in model systems, shRNA is the tool of choice. Therapeutic RNAi drugs like patisiran (FDA 2018) use modified siRNA, while research-grade shRNA libraries remain the standard in functional genomics.
