Chemical biology and drug discovery: Molecular sensors for quantitative optical imaging of cellular processes: Lipid-targeting drugs for cancer and neurodegenerative diseases: Roles of membrane lipids and lipid binding proteins in cancer, aging, and neurodegenerative diseases

Cellular processes, such as cell signaling, are mediated by myriad of molecular interactions that are exquisitely coordinated and tightly regulated. Our recent studies have shown that membrane lipids play key roles in orchestrating this complex regulation. Our current research focuses on i) understanding how lipids perform their regulatory actions, ii) discovering their new functions in health and disease, iii) and developing new and novel lipid-targeting drugs to treat diverse human diseases caused by dysfunctional lipid-mediated processes, including cancer, neurodegenerative diseases, and autoimmune diseases diseases.

(1) Seeing is believing and it is numbers that matter

Lipids are dynamic regulatory molecules and their cellular function depends on their subcellular location and local concentration. Our innovative in situ quantitative lipid imaging technology (Nature Chemistry, 2011; Nature Chemical Biology, 2017; Molecular Cell, 2018) has not only demonstrated high-resolution spatiotemporal dynamics of various lipids but also helped us discover their new cellular function in health and disease. We continue to develop fluorescence-based ratiometric sensors for simultaneous and quantitative imaging of lipids, lipid-binding proteins, and membrane dynamics in diverse live cells and tissues, including patient-derived samples, to elucidate the complex mechanisms of lipid-mediated cell regulation and identify new targets for drug discovery. We are also developing new chemical biology tools that allow spatiotemporally specific manipulation of lipid actions in live cells.

Our new LPI inhibitor, WC36 (highlighted in blue in a circle), specifically blocks both catalytic and scaffolding activity of Syk that plays a key role in the pathogenesis of acute myeloid leukemia (AML), preventing AML cells from developing resistance to WC36.

(2) Lipids as master regulators of cellular processes and new targets for drug discovery

Our studies have shown that membrane lipids serve as tunable switches that spatiotemporally orchestrate compartmentalization, mutual interaction, and activation of cellular proteins including those involved in human diseases (Molecular Cell, 2012: Molecular Cell, 2016). Our work has also shown that the cellular activity of these proteins can be specifically controlled by modulating their lipid binding. Based on these discoveries, we have developed a first-in-class small molecule lipid-protein interaction (LPI) inhibitor for a non-receptor tyrosine kinase (Nature Chemical Biology, 2023). LPI inhibitors offer major advantages over conventional ATP-competitive inhibitors in terms of specificity and refractoriness to drug resistance. Our current work focuses on developing novel LPI inhibitors as drug candidates for cancer, neurodegenerative diseases, and autoimmune diseases diseases.

(3) Multi-talented cholesterol: An emerging star in cancer and neurodegenerative diseases

Cholesterol is a major lipid component of the mammalian plasma membrane and its involvement in cardiovascular diseases is well documented. More recently, cholesterol has been linked to human cancers and neurodegenerative diseases, most notably Alzheimer’s disease, but the underlying mechanisms are poorly understood. We recently discovered that cholesterol directly and specifically activates cell signaling proteins, which leads to cell growth and proliferation (Nature Communications, 2012, 2014). Using our ratiometric cholesterol sensors and site-specific cholesterol modulation system, we also discovered that spatiotemporally specific enrichment of cholesterol is crucial for its cellular regulatory function (Nature Chemical Biology, 2017). Furthermore, cancer cells maintain cell type-specific local cholesterol levels that drive cancer progression and also serve as new cancer biomarkers. Based on these exciting new discoveries, we are currently developing new cholesterol-targeting LPI inhibitors for various human cancers, including breast cancer and colorectal cancer. The same approach is also being applied to the development of novel therapy for Alzheimer’s disease and autoimmune diseases.
