Reference excerpt

Paola A. Marignani is a scientist and Full Professor at Dalhousie University in the Faculty of Medicine, Department of Biochemistry and Molecular Biology. She is best known for her research on the tumor suppressor kinase LKB1, and its role in regulating the chromatin remodeling protein SMARCA4 and modeling metabolic processes in breast and lung cancers.

Biography Marignani completed her Hon BSc in Biology from the University of Windsor, followed by an MSc in Neurobiology from the University of Western Ontario. She earned her PhD in Cell Biology from McMaster University. Her postdoctoral training took place at Harvard Medical School in the Division of Signal Transduction followed by the Lunenfeld-Tanenbaum Research Institute and the Ontario Cancer Institute in Toronto, Ontario. She also holds an Executive MBA from the Ivey School of Business at Western University, and a certificate from MIT Sloan School of Management in Artificial Intelligence in Health Care. Marignani is also a scientist mentor at the Creative Destruction Lab and scientific director of the QEII Lung Tumour Bank.

Scientific career Marignani is known for research in tumor-suppressing proteins, notably LKB1. In 2001, Marignani discovered the first binding partner of LKB1, specifically SMARCA4, a chromatin remodeling protein. In subsequent studies, Marignani discovered that LKB1 regulates estrogen receptors in breast tissue. Her further research led to the discovery that LKB1 expression in HER2+ breast cancer is reduced or lost. This discovery led to the development of a HER2/ErbB2 mouse model where lkb1 expression was re-engineered. The resulting mice developed mammary tumors quicker than control mice, and the tumors were hyperactive for mTOR and cancer metabolism. Marignani combines technologies such as single-cell transcriptomics and machine learning to interrogate disease processes and discover targeted therapies in the framework of precision medicine. Marignani also researches disparities in cancer incidence and outcomes within a Black Canadian community in South Shelburne, Nova Scotia. This initiative is part of a broader project funded by the New Frontiers in Research Fund, and seeks to shed light on historical and ongoing systemic issues related to healthcare access and quality. In addition to funding from Breast Cancer Canada for her research in identifying unique markers associated with HER2+ breast cancer recurrence, Marignani has also been funded by NSERC, CIHR, and the Canadian Foundation for Innovation. She has also been awarded for Excellence in Cancer Research by the Canadian Cancer Society. Marignani's earlier research focused on understanding the molecular changes to signaling molecules resulting from polyunsaturated fatty acid incorporation into lipid membranes. She discovered that the integration of eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) into lipid membranes altered diacylglycerol profiles in murine macrophages, which could lead to downstream changes in signaling events.

Worked examples

Example 1 — a first encounter with Paola Marignani

Start with the simplest possible case. Write down what Paola Marignani claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In chemistry, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Paola Marignani before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Paola Marignani ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Paola Marignani

In research: Paola Marignani appears in chemistry research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Paola Marignani in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Paola Marignani is common in secondary-school and first-year university syllabi. It links to neighbouring topics 20th-century Canadian scientists, 20th-century Canadian women scientists, 21st-century Canadian scientists, so understanding it makes those chapters shorter.
In everyday life: Look for Paola Marignani outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
