1. Deep learning of multiplexed mitochondrial morphology identified natural compound combinations against skin photoaging.
Using AI-assisted high-content analysis of mitochondrial morphology, the authors identified five mitochondrial-protective natural products and optimized two combinations (CC-1, CC-2) that restored ATP/TCA flux, normalized mitochondrial morphology, and reduced senescence markers via SIRT3 upregulation in UVB-exposed human dermal fibroblasts. Efficacy translated in vivo, with CC-2 enhancing fin regeneration in UVB-exposed zebrafish and outperforming in UVB-irradiated mice, supporting development as a cosmetic additive.
Impact: Combining AI-driven phenotypic screening with cross-species validation provides a rigorous pipeline to discover mitochondrial-targeted anti-photoaging interventions, revealing SIRT3-mediated mechanisms and robust in vivo efficacy.
Clinical Implications: Supports development of SIRT3-boosting, mitochondrial-targeted cosmeceuticals to prevent or mitigate photoaging; informs biomarker-driven formulation screening prior to human testing.
Key Findings
- AI-assisted high-content screening identified quercetin, spermidine, adenosine, vitamin K2, and Mirabilis jalapa extract as mitochondrial-protective agents.
- Two combinations (CC-1, CC-2) restored ATP production, TCA cycle flux, and mitochondrial morphology, lowered SA-β-gal activity, and increased COLLAGEN I, LAMIN B1, and SIRT3 in UVB-exposed HDFs.
- CC-2 promoted fin regeneration in a UVB-exposed zebrafish tail amputation model and showed superior efficacy in UVB-irradiated mice.
- Senescence alleviation was mechanistically linked to SIRT3 upregulation.
Methodological Strengths
- AI-assisted, multiparametric high-content phenotypic screening of mitochondrial morphology and function
- Cross-species validation across in vitro human cells, zebrafish, and mouse UVB models
Limitations
- No human clinical trial data; translational efficacy and safety in humans remain untested
- Natural product variability and formulation stability were not addressed in real-world cosmetic matrices
Future Directions: Quantify dose–response and SIRT3 dependency using genetic perturbation; test CC-2 in ex vivo human skin and early-phase clinical studies; evaluate formulation stability and dermal penetration.
BACKGROUND: Skin photoaging is primarily driven by mitochondrial dysfunction. Although natural products have demonstrated protective effects against Ultraviolet (UV)-induced damage, efficient screening strategies for mitochondrial-targeting compounds remain limited. Artificial Intelligence (AI)-assisted high-content screening strategy offers a valuable approach to identify bioactive candidates and elucidate their mechanisms. PURPOSE: This study aimed to employe an AI-assisted high-content screening strategy to identify mito
2. Triparental synthetic yeast hybrids as a platform for higher 2-phenylethanol yields and stress resistance.
Triparental yeast hybrids (H1–H5) achieved up to 3 g/L 2-phenylethanol within 72 hours across media, with up to 9-fold gains versus parents and improved tolerance (e.g., H1 retained 61% growth at 4 g/L 2-PE). The hybrids combine production capacity from one parent and tolerance from another, demonstrating a robust, non-GMO route to build resilient yeast factories for cosmetic fragrance ingredients.
Impact: Demonstrates a scalable, non-GMO breeding strategy that overcomes 2-PE cytotoxicity and boosts titers, addressing a key bottleneck in sustainable cosmetic ingredient manufacturing.
Clinical Implications: No direct clinical impact; indirectly supports safer, cost-effective, and sustainable supply of cosmetic fragrance ingredients, potentially reducing impurities from extraction-based sourcing.
Key Findings
- Triparental hybrids reached up to 3 g/L 2-phenylethanol within 72 hours across multiple cultivation media.
- Production increases up to 9-fold compared with parental strains, robust across tested conditions.
- Enhanced tolerance to exogenous 2-PE; e.g., H1 retained 61% growth at 4 g/L 2-PE.
- Hybrids combined advantageous traits from both parents, sometimes surpassing each.
Methodological Strengths
- Comprehensive phenotypic benchmarking across multiple hybrids, parents, and media conditions
- Concurrent evaluation of productivity and tolerance with quantitative growth and titer readouts
Limitations
- Lack of genomic/omics characterization to map genotype–phenotype contributions
- Scale-up and process integration (bioreactors, downstream purification) not demonstrated
Future Directions: Integrate systems genetics to identify alleles driving tolerance and production; validate performance in bioreactors with in situ product removal to mitigate toxicity.
2‑Phenylethanol (2‑PE) is a valuable aromatic alcohol widely used in the cosmetic, food, and pharmaceutical industries, yet its cytotoxicity remains a major bottleneck for microbial production. In this study, we evaluated a set of previously constructed triple hybrid yeast strains (H1-H5), derived from S. cerevisiae 10‑170 and the double hybrid II/6, to assess their potential for enhanced 2‑PE biosynthesis and tolerance. Comprehensive phenotypic analysis revealed that the triple hybrids consistently outpe
3. Lab-on-a-tip platform with cotton matrices for colorimetric detection of carmine in lipsticks.
A simple cotton-based lab-on-a-tip was developed for colorimetric detection of carmine via acid conversion to carminic acid and complexation with ferric chloride, yielding a brown chromogen proportional to concentration. Cotton outperformed filter paper due to its 3D fibrous network, achieving an experimental LOD of 0.5 mg/mL and reproducible, visibly distinguishable color across the tested range.
Impact: Offers a low-cost, rapid, and portable method to detect a common cosmetic dye linked to allergic reactions and ethical concerns, enabling point-of-use screening by non-specialists.
Clinical Implications: Facilitates consumer and occupational screening for carmine in lipsticks, aiding avoidance in allergic individuals and supporting labeling transparency; potential integration with smartphone readouts.
Key Findings
- A cotton-based lab-on-a-tip device enabled colorimetric detection of carmine via acid conversion and FeCl3 complexation.
- Cotton matrices produced stronger, more sensitive color responses than filter paper due to a 3D fibrous network.
- The experimentally determined limit of detection was 0.5 mg/mL with reproducible and distinguishable color across the tested range.
Methodological Strengths
- Simple, reagent-embedded cotton matrices enabling portable, equipment-free detection
- Head-to-head comparison with filter paper demonstrating superior sensitivity of cotton
Limitations
- Interference from common lipstick excipients and colorants was not systematically evaluated
- Real-world validation across diverse commercial products and user-operated settings was not reported
Future Directions: Validate against a broad panel of commercial lipsticks, assess matrix interference, and integrate quantitative smartphone-based color analysis.
Carmine is a natural red dye derived from cochineal insects and is widely used in cosmetics and food products. Since carmine is derived from insects, individuals who follow vegan or vegetarian lifestyles and those who have religious beliefs may wish to ascertain its presence in the products they use. Additionally, carmine causes angioedema, urticaria, contact dermatitis, systemic anaphylaxis and even asthma in hypersensitive individuals. Conventional methods for detecting the presence of carmine require
