Oncology meets marine biology: When mussels spill the secrets of their environment

Published

INRS oncology experts use liquid biopsy to investigate the quality of marine ecosystems.

LAVAL, QC, July 23, 2024 /CNW/ – How can a team of oncology specialists provide insight into the effects of climate change on marine ecosystems? This is the challenge that a team from the Institut national de la recherche scientifique (INRS) brilliantly tackled under the supervision of Professor Yves St-Pierre and doctoral student Sophia Ferchiou, applying the principles of liquid biopsy—a technique used in early cancer detection—to the mussels of Quebec.

Medicine on call for biodiversity
By their very nature, mussels act as filters within their environment. As such, they are excellent bioindicators for assessing marine ecosystems. The research team therefore applied principles of liquid biopsy to the mollusks in order to investigate their ecosystem.

In humans, liquid biopsy involves analyzing DNA circulating in the bloodstream for evidence of cancer. It provides valuable indications of the type of cancer the patient has, the stage to which it has progressed, and the mutations generated by the disease. Since mussels retain traces of everything that enters their environment, liquid biopsy can provide significant insight into the ecological situation.

“The innovation lies in the use of new technology, i.e., multi-omic analysis, with which we can detect mutations, genetic and epigenetic changes, as well as DNA derived from organisms such as viruses, parasites, bacteria, and even certain species of fish in a given ecosystem,” explained Professor Yves St-Pierre, INRS oncology specialist. The researcher, who is based at the Armand-Frappier Santé Biotechnologie Research Centre in Laval, observed: “We are at the junction between biomedical science and marine biology.”

The liquid biopsy consisted of analyzing the hemolymph—a fluid analogous to blood in vertebrates—of several thousand mussels, providing a veritable treasure trove of environmental data and information.

“We are following the same course as we would with a cancer patient,” Professor St-Pierre stated. “We diagnose the disease, prescribe treatment, and then follow up on developments. The sooner we can detect signs of cancer or, in this case, environmental problems, the sooner we can intervene. With liquid biopsy, we are applying the same methodology and even the same philosophy to biodiversity.” 

A collaborative approach rooted in fieldwork
This project is currently at the heart of the work led by doctoral student Sophia Ferchiou at INRS. “My research consists of using mussels as a sentinel species, i.e., a species highly sensitive to changes in its environment, to assess the health status of marine and coastal ecosystems,” stated the marine biology student, who studies under the joint direction of Professor Yves St-Pierre and Stéphane Betoulle of the University of Reims.

The team conducts its research in close collaboration with Parks Canada biologists at four Quebec sites: Moulin-à-Baude, Cap-de-Bon-Désir and Pointe-à-John on the coast of Saguenay-St. Lawrence Marine Park, and Parc national du Bic, managed by Sépaq. Each site has its own distinctive features, such as proximity to domestic and agricultural wastewater disposal or a discovery and observation centre. Key differences have already been observed between these locations.

“By applying medical techniques to marine ecosystems, not only can we make a diagnosis, but we can also observe warning signs for future issues that are likely to affect an ecosystem. Are there traces of chemicals or signs of a viral outbreak? We can therefore apply early corrective measures, which we will monitor regularly using liquid biopsy,” Sophia Ferchiou highlighted.

Initially led by the doctoral student once a month since 2019, these sample collections now take place on a weekly basis thanks to the participation of Parks Canada biologists across the different sites, providing a unique opportunity to regularly monitor the ecosystems. “This partnership has enabled us to collect an extraordinary number of samples,” Sophia Ferchiou exclaimed. “Our study demonstrates the effectiveness of multi-omic analysis of liquid biopsies sampled from mussels to observe their biological response to environmental stress.”

“One of our conservation team’s mandates is to determine and monitor the health of the ecosystems in the Saguenay–St. Lawrence Marine Park. The approach proposed by INRS is part of a series of scientific monitoring projects carried out by our team and various partners to gain a better understanding of the changes and threats to the marine park’s ecosystems. Not only is the method innovative and promising, but it is also non-invasive and relatively simple to apply in the field. We are very pleased to be able to work with the team and rely on their expertise.”

About the study
The article entitled “Assessing marine ecosystem health using multi-omic analysis of blue mussel liquid biopsies: A case study within a national marine park” published in the journal Chemosphere, was coauthored by Sophia Ferchiou, France Caza, Kumardip Sinha, Janelle Sauvageau, and Yves St-Pierre. DOI:10.1016/j.chemosphere.2024.142714.

SEOUL, South Korea, May 5, 2026 /PRNewswire/ — The Korea Institute of Science and Technology (KIST) President Oh Sang-rok announced that it will participate in the SelectUSA Investment Summit 2026 as part of a Korean delegation, together with quantum technology startups supported by the Ministry of SMEs and Startups under the Deeptech Project (DIPS).

The initiative, supported by South Korea’s Ministry of SMEs and Startups (MSS), is part of the government’s “Deeptech Incubator Project for Startups” (DIPS) initiative, which aims to nurture globally competitive deep-tech ventures.

KIST, which serves as the lead institution for the quantum technology sector under the program, said it will oversee the global commercialization efforts of participating firms. In particular, the “Global Bridge Program,” jointly developed with the U.S. Embassy in Korea in September 2025, is an official program designed to generate tangible overseas expansion outcomes by linking investment attraction with local market entry through diplomatic channels.

Organized by the U.S. Department of Commerce, the SelectUSA Investment Summit is the largest investment promotion event in the US, connecting international startups with venture capital firms, corporate investors and state-level economic development agencies.

It serves as an execution-oriented platform that extends to investment, corporate establishment, site selection, and tax incentives, and is considered a key entry gateway for deep-tech companies, including those in quantum technology.

KIST said participation in the summit is particularly significant for deep-tech sectors such as quantum technology, where access to the US innovation ecosystem is seen as key to growth.

The program is conducted in two stages. From April 30 to May 1, companies took part in a spin-off program hosted by the State of Maryland, which included visits to research institutions and tours of the regional quantum technology ecosystem.

During this period, the delegation also conducted localized activities with the Maryland state government and its economic development agencies, focusing on investment attraction, corporate collaboration, and joint R&D. In addition, on May 5, the delegation held discussions with U.S. Department of Commerce Deputy Secretary William Kimmitt on potential areas of cooperation.

The delegation will also meet officials from Fairfax County Government to explore collaboration and investment opportunities.

The main summit, currently ongoing from May 3 to May 6, features exhibitions, pitching sessions and meetings with US state representatives, with participating firms expected to engage in discussions on investment and market entry.

The delegation is structured to encompass the entire quantum industry rather than a single technology domain.

The Korean delegation comprises five startups, alongside Kyung Hee University Department of Future Science & Technology Commercialization Policy and Entrepreneurship, with approximately 20 participants forming an integrated ecosystem that combines research institutes, academia, and startups, enabling a full-cycle support system from technology validation to commercialization and global expansion.

One of the firms, OptiQ-Labs, was selected for an official pitching session on May 4, where it presented its laser-based optical modules designed for ion-trap quantum computing systems.

This highly competitive program selects only around 100 companies from more than 20,000 applicants worldwide. If selected as the winner of the pitching session, the company will receive follow-up meetings with U.S. state governments and economic development agencies, access to global investor networks, support for local entity establishment, and connections to site selection and tax incentive programs.

Other participating companies include QUAD, which develops single-photon detection technology; SLEEX, focused on underwater sensing; Elixir (StatUp AI), which works on quantum-classical hybrid algorithms for healthcare; and SQK (QMEDIC), specializing in physics-based imaging solutions.

KIST Project Director, Kang Sunjoon, said, “This program represents a critical milestone for Korean quantum startups to directly connect with global investors and industry ecosystems. Via the DIPS program, we are actively promoting the global commercialization of quantum technologies.”

Through its participation in SelectUSA, KIST has established a package-type global expansion model that integrates technology validation, investment attraction, and U.S. market entry.
