Welcome to the Zinovyeva lab
microRNAs are small non-coding RNAs that post-transcriptionally regulate expression of many genes. microRNA activity is essential, and alterations in miRNA expression and function have been associated with many developmental pathologies and diseases. Thus, microRNAs are of great interest as diagnostic and therapeutic targets. However, to efficiently inhibit or promote microRNA activity in pathological conditions, we must first have a detailed understanding of all aspects of miRNA biogenesis and function.
microRNAs undergo a complex process of biogenesis. Pictured (on right) is the canonical microRNA production pathway that includes multiple processing steps and culminates in the formation of the microRNA Induced Silencing Complex (miRISC). While we know a lot about how microRNAs are made, we lack detailed understanding of how the steps of microRNA biogenesis are regulated at the molecular level.
Our lab is interested in two questions:
1. How is microRNA production and function regulated during development?
2. How is a single microRNA strand selected from the precursor duplex in vivo and how might this process of strand selection be regulated?
We use a number of different approaches to address these questions. These approaches include forward and reverse genetics, molecular biology, biochemistry and proteomics, and last but not least, CRISPR genome editing and genomics. We use a small nematode worm, Caenorhabditis elegans, as our model organism of choice. As both RNAi and microRNAs were first discovered in C. elegans, there is a wealth of small RNA knowledge in “the worm” that provides a solid foundation for our work. We hope to add to that knowledge by asking specific questions and testing specific hypotheses on regulation of microRNA biogenesis and function. Ultimately, we hope that the insights we gain into microRNA regulation will contribute to development of better microRNA-centered diagnostic and therapeutic tools.
