Microalgae biorefinery in the belt and road initiative: opportunities for green growth

Review

Author: Liu, Ziyu ; Lei, Dingkun ; Zhang, Zimeng ; Yang, Jin

In the context of global energy transformation and climate change, the microalgae industry has emerged as a strategic avenue for promoting green development, driven by its energy conservation, emission reduction, and resource recycling advantages. As a key advocate of the Belt and Road Initiative (BRI), China has increasingly integrated green development into its cooperation framework, fostering the application of microalgae technology in BRI countries and contributing to achieving both environmental and economic goals. This paper reviews the advancements in microalgae technology within bioenergy, high-value product development, and environmental sectors. This review differs from existing studies by systematically linking technological advances in microalgae biorefining with the BRI framework. It examines the entire biorefinery chain-from cultivation to product valorization-while emphasizing improvement measures at each stage, including hybrid cultivation systems to reduce costs, advanced extraction methods to enhance yields, and integrated biorefinery models to optimize resource efficiency. A technology-market matching analysis further reveals that while biofuels face high demand but limited technological maturity, high-value products such as astaxanthin and EPA/DHA show stronger alignment with current market growth. Future efforts should focus on establishing joint pilot-scale facilities, harmonizing green trade standards, and strengthening multilateral cooperation under the BRI. By combining technological innovation with international collaboration, microalgae biorefining can become a key driver of sustainable economic transformation and contribute to achieving global low-carbon goals.

Bioremediation of marine shrimp wastewater using high-light-tolerant Rose Bengal mutants of Nannochloropsis oceanica offers a climate-resilient method for co-producing eicosapentaenoic acid under warming and flue gas CO₂

Article

Author: Lee, Tse-Min ; Yeh, Chia-Chen ; Wang, Yu-Hsin

This study investigates high-light-tolerant Nannochloropsis oceanica Rose Bengal mutants (RB2 and RB113) for bioremediation of shrimp aquaculture wastewater (SWW) under increased temperature and light, simulating future climate change. Cultivations were performed under 250 μmol photons m^-2·s^-1 with flue gas CO₂ supply. At 18 °C, RB mutants and wild-type (WT) strain showed similar growth. At 25 °C, representative of warming in subtropical and temperate regions, the RB113 mutant outperformed WT and RB2 in terms of biomass accumulation, photosynthetic efficiency, and non-photochemical quenching. Temperature-dependent nutrient removal patterns revealed that while WT effectively removed inorganic nitrogen and phosphorus, RB113 prioritized biomass and lipid production, highlighting a trade-off between remediation and bioresource accumulation. CO₂ capture was estimated at its highest at 25 °C in RB113 (381 tons CO₂ ha/year). On day 2, under initial nitrogen starvation, RB113 produced 9.95 mg/g DW of eicosapentaenoic acid (EPA) with a peak productivity of 2.338 mg/L/day. By day 5, prolonged nitrogen depletion caused EPA to decline to 3.57 mg/g DW, while total fatty acids doubled to 63 mg/g DW, with a dominance of saturated forms, indicating a shift toward storage lipids. These results suggest that RB113 has significant potential as a climate-adapted bioresource, capable of integrating wastewater remediation, carbon capture, and high-value EPA production, without the need for low-temperature induction. As global temperatures rise and aquaculture expands, this climate-resilient method offers sustainable inland marine aquaculture management by reducing nutrient pollution, with additional benefits of mitigating greenhouse gases and transforming wastewater into valuable products.

Tom70 prevents fibrotic activation of aortic valve interstitial cells via EPA-activated Autophagic flux

Article

BACKGROUND:

Translocase of outer mitochondrial membrane 70 (Tom70) has been implicated in the development of various cardiovascular diseases. However, its role in aortic valve fibrosis, an important feature of calcific aortic valve disease (CAVD), remains unclear.

OBJECTIVE:

This study aims to explore the potential role of Tom70 in aortic valve fibrosis, with a view to providing new insights into the clinical management of CAVD.

METHODS:

Proteomics, metabolomics and enrichment analysis were used to screen for differential molecules and signaling pathways. Western Blot (WB) and quantitative real-time polymerase chain reaction (qRT-PCR) were employed to detect the expression levels of Tom70 and autophagy-related proteins. Gain- and loss-of-function experiments of Tom70 were conducted both in vivo and vitro to investigate its role in aortic valve fibrosis. Immunofluorescence staining, Masson staining, etc. were used to evaluate fibrosis. Confocal microscopy and transmission electron microscope (TEM) were utilized to detect autophagic flux.

RESULTS:

The expression of Tom70 was significantly downregulated in fibrocalcific aortic valve tissues from patients and in aortic valve interstitial cells (AVICs) following TGF-β1 stimulation. In vivo experiments revealed that Tom70 knockout exacerbated aortic valve fibrosis in rat. Mechanistic studies in rat AVICs indicated that impaired autophagic flux accelerates fibrotic activation in AVICs, and Tom70 modulates fibrotic activation through the regulation of autophagic flux. In addition, we identified eicosapentaenoic acid (EPA) as a key regulator of autophagic flux influenced by Tom70.

CONCLUSION:

Overall, our study unveils a novel role of Tom70 in aortic valve fibrosis and elucidates its regulatory relationship with autophagic flux, providing new insights into the molecular mechanisms underlying CAVD.

In oncology, in September 2025, the U.S. Food and Drug Administration (FDA) approved KEYTRUDA QLEX injection for subcutaneous (SC) administration for use in adults across most solid tumor indications for KEYTRUDA, based on results from the Phase 3 MK-3475A-D77 trial. In October 2025, the FDA subsequently approved KEYTRUDA QLEX for the treatment of certain adult patients with resectable locally advanced head and neck squamous cell carcinoma (LA-HNSCC), based on results from the Phase 3 KEYNOTE-689 trial. KEYTRUDA QLEX is now approved for use in adults across all solid tumor indications approved for KEYTRUDA and is the first and only subcutaneously administered immune checkpoint inhibitor that can be given by a health care provider in as little as one minute. In addition, the European Medicines Agency’s Committee for Medicinal Products for Human Use (CHMP) adopted a positive opinion recommending approval for SC administration of KEYTRUDA for all adult indications; a final decision is expected in the fourth quarter of 2025. The European Commission (EC) also approved KEYTRUDA as part of a perioperative regimen for the treatment of PD-L1+ resectable LA-HNSCC. At the European Society for Medical Oncology (ESMO) Congress 2025, the Company announced new research from its broad and differentiated portfolio and pipeline, highlighting progress in new tumor types and earlier stages of disease. This included positive results from the Phase 3 KEYNOTE-905 trial (also known as EV-303) in cisplatin-ineligible patients with muscle-invasive bladder cancer (MIBC), the Phase 3 KEYNOTE-B96 trial in platinum-resistant recurrent ovarian cancer and the Phase 2/3 REJOICE-Ovarian01 trial in collaboration with Daiichi Sankyo in certain types of platinum-resistant ovarian cancer, long-term follow-up data from the Phase 3 KEYNOTE-775 trial in advanced endometrial cancer, as well as long-term data for KEYTRUDA in both earlier-stage and metastatic NSCLC. In vaccines and infectious diseases, in August 2025, the Company received two approvals in Japan: its nine-valent HPV vaccine for use in males ages 9 and older that will be marketed under the trademark SILGARD 9, and CAPVAXIVE for use in the elderly or adults who are at an increased risk of pneumococcal disease. At the European AIDS Clinical Society 2025 conference, the Company also presented new data from Phase 3 trials evaluating the once-daily, oral, two-drug regimen of doravirine/islatravir in adults with virologically suppressed HIV-1 infection, which showed minimal changes in weight and body composition and no clinically meaningful effect on fasting lipids and the homeostatic model assessment of insulin resistance across both clinical trials. In cardiovascular disease, the Company announced positive topline results from the Phase 3 CORALreef Lipids trial evaluating the safety and efficacy of enlicitide decanoate, an investigational, once-daily oral proprotein convertase subtilisin/kexin type 9 (PCSK9) inhibitor being evaluated for the treatment of adults with hypercholesterolemia. The trial met all primary and key secondary endpoints. Enlicitide has the potential to be the first approved oral PCSK9 inhibitor. In addition, the FDA approved an update to the U.S. product label for WINREVAIR, based on results from the Phase 3 ZENITH trial, expanding the indication to include components of the clinical worsening events: hospitalization for pulmonary arterial hypertension (PAH), lung transplantation and death. Further, at the 2025 European Respiratory Society Congress, the Company presented positive results from the Phase 3 HYPERION trial evaluating WINREVAIR versus placebo (both in combination with background therapy) in adults recently diagnosed with PAH (Group 1 pulmonary hypertension) with World Health Organization (WHO) functional class II or III at intermediate or high risk of disease progression. Results showed that adding WINREVAIR within the first year after PAH diagnosis significantly reduced the risk of clinical worsening events compared to placebo. The Company also completed its acquisition of Verona Pharma plc (Verona Pharma) in October 2025, strengthening its cardio-pulmonary portfolio with the addition of OHTUVAYRE, an FDA-approved, first-in-class maintenance treatment for chronic obstructive pulmonary disease (COPD) in adult patients.

This investment is part of the Company’s commitment to dedicate more than $70 billion beginning in 2025 to expand domestic manufacturing and R&D — not including any future business development in R&D — to drive its long-term growth and strengthen the U.S. as a global leader in biopharmaceutical innovation. Upcoming Investor Event The Company also plans to present new data from its innovative cardiovascular pipeline and portfolio at the American Heart Association (AHA) Scientific Sessions 2025 from Nov. 7-10. The Company will host an Investor Event to coincide with the AHA Scientific Sessions 2025 on Sunday, Nov. 9 at 6 p.m. CT. The event will take place in New Orleans and will be accessible via live audio webcast at this weblink. Sustainability Highlights The Company’s 2024/2025 Purpose for Progress Impact Report provided a comprehensive view of how it is pursuing innovative science for the health of people and animals and ensuring its efforts drive significant and sustainable value. The report noted that the Company’s medicines and vaccines reached more than 450 million people around the world in 2024. Full-Year 2025 Financial Outlook The following table summarizes the Company’s full-year financial outlook. Full Year 2025 Updated Prior Sales* $64.5 billion to $65.0 billion $64.3 billion to $65.3 billion Non-GAAP Gross margin2 Approximately 82% Approximately 82% Non-GAAP Operating expenses2(a) $25.9 billion to $26.4 billion $25.6 billion to $26.4 billion Non-GAAP Other (income) expenses, net2 $400 million to $500 million expense $300 million to $400 million expense Non-GAAP Effective tax rate2 14.0% to 15.0% 15.0% to 16.0% Non-GAAP EPS2(b)(c) $8.93 to $8.98 $8.87 to $8.97 Share count (assuming dilution) Approximately 2.51 billion Approximately 2.51 billion *The Company does not have any non-GAAP adjustments to sales. (a)Includes one-time R&D charges of $300 million for a milestone payment to LaNova associated with the technology transfer for MK-2010 and $200 million for an upfront payment for a license agreement with Jiangsu Hengrui Pharmaceuticals Co., Ltd. (Hengrui Pharma). Outlook does not assume any additional significant potential business development transactions. (b)Includes one-time charges totaling $0.16 per share associated with the payment for the LaNova technology transfer for MK-2010 and the upfront payment to Hengrui Pharma. (c)Updated full-year 2025 outlook reflects a benefit of approximately $0.09 per share resulting from an amendment to the collaboration agreement with AstraZeneca related to Koselugo, and an estimated negative impact of $0.04 per share related to the acquisition of Verona Pharma. The Company has not provided a reconciliation of forward-looking non-GAAP gross margin, non-GAAP operating expenses, non-GAAP other (income) expense, net, non-GAAP effective tax rate and non-GAAP EPS to the most directly comparable GAAP measures, given it cannot predict with reasonable certainty the amounts necessary for such a reconciliation, including intangible asset impairment charges, legal settlements, and income and losses from investments in equity securities either owned directly or through ownership interests in investment funds, without unreasonable effort. These items are inherently difficult to forecast and could have a significant impact on the Company’s future GAAP results. The Company now expects full-year 2025 sales to be between $64.5 billion and $65.0 billion, including a negative impact of foreign exchange of approximately 0.5% at mid-October 2025 exchange rates. The Company now expects its full-year non-GAAP effective income tax rate to be between 14.0% and 15.0%. The Company now expects its full-year non-GAAP EPS to be between $8.93 and $8.98, including a negative impact of foreign exchange of approximately $0.15 per share. This revised non-GAAP EPS outlook reflects several items not previously included, such as a benefit from an amended collaboration agreement with AstraZeneca related to Koselugo, and operational improvements, including a more favorable estimated tax rate and lower estimated costs related to the impact of tariffs, partially offset by an estimated negative impact related to the acquisition of Verona Pharma and an incremental negative impact from foreign exchange. The midpoint of this revised non-GAAP EPS range reflects a net improvement of $0.04 per share compared to the midpoint of the Company’s prior outlook. As previously communicated, the revised estimated full-year 2025 non-GAAP EPS range reflects the impacts of the one-time charges in connection with a license agreement with Hengrui Pharma and the completion of the technology transfer with LaNova for MK-2010, which impact EPS by approximately $0.16 in the aggregate. In 2024, non-GAAP EPS of $7.65 was negatively impacted by a net charge of $1.28 per share related to certain asset acquisitions, licensing agreements and collaborations. Consistent with past practice, the financial outlook does not assume additional significant potential business development transactions.

Omega-3 benefits may vanish quickly after you stop

Finnish scientists found that eicosapentaenoic acid (EPA) from fish oil impacts each person’s metabolism uniquely. Participants showed strong but short-lived increases in EPA levels, with significant differences in lipid pro The results reveal how metabolism shapes individual responses to omega-3 supplements and underscore the need for personalized heart health strategies. A new study has found that the benefits of a fatty acid known as eicosapentaenoic acid vary widely from person to person. Researchers say the results highlight how individual metabolism plays a crucial role in protecting against cardiovascular disease. Scientists in Finland explored how eicosapentaenoic acid (EPA), an omega-3 fatty acid found in fish oil, affects metabolism and blood lipid levels in healthy adults. While EPA is already recognized for lowering cardiovascular risk in people with high cholesterol or heart disease, its effects in otherwise healthy individuals have not been well understood. Little was also known about how EPA becomes incorporated into lipoproteins, the particles that transport fat molecules through the bloodstream. High-Dose Supplement Study Reveals Wide Variation In this research, 38 volunteers were given unusually high doses of EPA supplements. Blood samples were collected before, during, and after supplementation to observe how the body processed the fatty acid. The results showed large differences among participants in how their bodies responded to EPA. "The samples taken during supplementation clearly show the effect of EPA on all participants. Having said that, all samples were different among the group. In other words, each individual has a unique lipoprotein lipidome in their circulation, a 'lipid fingerprint', if you will, that persisted despite EPA supplementation," explains Professor Katariina Öörni, one of the lead authors from the Faculty of Biological and Environmental Sciences, University of Helsinki, and the Wihuri Research Institute. The researchers confirmed that EPA is absorbed efficiently, causing a sharp rise in its concentration in the blood. However, the levels declined quickly once supplementation stopped. The strongest changes were observed in participants who started with lower baseline EPA levels. In addition, EPA improved blood lipid profiles and reduced the tendency of lipoproteins to attach to the walls of arteries -- an important factor in preventing atherosclerosis. Short-Term Effects and Future Research Because the study lasted only a short time, it did not measure long-term outcomes. Still, the findings reveal that EPA can alter blood lipid composition and influence early risk mechanisms for atherosclerosis even in healthy people. "The findings highlight the importance of metabolism in the prevention of cardiovascular diseases. EPA's effects varied more between individuals than we expected. We also demonstrated that these effects dissipate quickly, which is good to know in case EPA were to have adverse effects," notes Doctoral Researcher Lauri Äikäs. Next, the team plans to study how EPA supplementation affects inflammatory cells and the production of lipid mediators that help control inflammation. "It's interesting to see how, for instance, dietary changes affect lipoprotein quality, or the individual lipid fingerprint," Öörni adds.

About VASCEPA®/VAZKEPA® (icosapent ethyl) Capsules VASCEPA (icosapent ethyl) capsules are the first prescription treatment approved by the U.S. Food and Drug Administration (FDA) comprised solely of the active ingredient, icosapent ethyl (IPE), a unique form of eicosapentaenoic acid. VASCEPA was launched in the United States in January 2020 as the first drug approved by the U.S. FDA for treatment of the studied high-risk patients with persistent cardiovascular risk despite being on statin therapy. VASCEPA was initially launched in the United States in 2013 based on the drug’s initial FDA approved indication for use as an adjunct therapy to diet to reduce triglyceride levels in adult patients with severe (≥500 mg/dL) hypertriglyceridemia. Since launch, VASCEPA has been prescribed more than twenty-five million times. VASCEPA is covered by most major medical insurance plans. In addition to the United States, VASCEPA is approved and sold in Canada, China, Australia, Lebanon, the United Arab Emirates, Saudi Arabia, Qatar, Bahrain, and Kuwait. In Europe, in March 2021 marketing authorization was granted to icosapent ethyl in the European Union for the reduction of risk of cardiovascular events in patients at high cardiovascular risk, under the brand name VAZKEPA. In April 2021 marketing authorization for VAZKEPA (icosapent ethyl) was granted in the United Kingdom (applying to England, Scotland, Wales, and Northern Ireland). VAZKEPA (icosapent ethyl) is currently approved and sold in Europe in Sweden, Finland, England/Wales, Spain, Netherlands, Scotland, Greece, Portugal, Italy, Denmark and Austria. United States Indications and Limitation of Use VASCEPA is indicated: As an adjunct to maximally tolerated statin therapy to reduce the risk of myocardial infarction, stroke, coronary revascularization and unstable angina requiring hospitalization in adult patients with elevated triglyceride (TG) levels (≥ 150 mg/dL) and established cardiovascular disease ordiabetes mellitus and two or more additional risk factors for cardiovascular disease. As an adjunct to diet to reduce TG levels in adult patients with severe (≥ 500 mg/dL) hypertriglyceridemia. The effect of VASCEPA on the risk for pancreatitis in patients with severe hypertriglyceridemia has not been determined. Important Safety Information VASCEPA is contraindicated in patients with known hypersensitivity (e.g., anaphylactic reaction) to VASCEPA or any of its components.VASCEPA was associated with an increased risk (3% vs 2%) of atrial fibrillation or atrial flutter requiring hospitalization in a double-blind, placebo-controlled trial. The incidence of atrial fibrillation was greater in patients with a previous history of atrial fibrillation or atrial flutter.It is not known whether patients with allergies to fish and/or shellfish are at an increased risk of an allergic reaction to VASCEPA. Patients with such allergies should discontinue VASCEPA if any reactions occur.VASCEPA was associated with an increased risk (12% vs 10%) of bleeding in a double-blind, placebo-controlled trial.
