Professional Statement
The lab focuses on microRNA-mediated posttranscriptional mechanisms in lung physiology and tissue repair following injury. We are particularly focused on how hijacking of microRNA pathways contribute to epithelial stem cell dysfunction in pathophysiology of chronic obstructive pulmonary disease (COPD) and Interstitial Lung Disease (ILD). COPD and ILD are serious disorders associated with irreversible damage to the lung and chronic inflammation. microRNA biology offers an innovative opportunity for interventions in these challenging diseases. Our research found that miRNA post-transcriptional signals and mechanisms are pivotal in lung stem cell dynamics, immune cell inflammation in COPD and ILD.
We and others have shown reduced expression of the let-7 miRNA family in human tissues and pre-clinical models of COPD and ILD. The let-7 miRNA family is an ancient and critically important gene associated with diseases such as cancer and organ fibrosis.
In the immune system, we recently demonstrated that let-7 directly controls ROR纬t expression which leads to excessive formation of IL17+ CD8+ T cells (Tc17), which sensitizes lungs of mice to injury and tissue destruction in COPD.
Within pulmonary alveolar type II (AT2) progenitor stem cells, we found that let-7 governs a maladaptive 鈥渃ancer-like鈥 molecular epigenomic program associated with an enhanced stem cell activation state which promotes lung injury, immune cell inflammation, fibrosis, and ILD.
Our lab utilizes unique animal models together with 3D organoid lung epithelial stem cell cultures to identify key regulatory mechanisms of microRNAs. We further make use of innovative techniques such as chimeric AGO2-eCLIP, scRNA-seq, and CUT&RUN.
Our work offers novel therapeutic strategies that can be used to treat severe lung diseases.
