1. Biomimetic recombinant collagen with multicopy dual-targeted hemostatic motifs for enhanced hemostasis in surgical trauma.
This paper introduces a biosynthetic strategy to engineer recombinant collagen by embedding multiple copies of dual hemostatic motifs (GFPGER and GPP) into a COL3A1 scaffold. The approach is designed to overcome the limited active sites and non-customizable motifs of native collagen, enabling dual-target engagement (including integrins) to enhance surgical hemostasis.
Impact: Engineered collagen with customizable, multicopy hemostatic motifs represents a potentially paradigm-shifting biomaterial for surgical and plastic procedures where bleeding control is critical.
Clinical Implications: If validated preclinically and clinically, this platform could yield next-generation topical hemostats and sealants for plastic, cosmetic, and trauma surgery, potentially reducing transfusions and operative time.
Key Findings
- Proposes a biosynthetic strategy for multicopy, dual-targeted recombinant collagen built on COL3A1.
- Integrates hemostatic motifs GFPGER and GPP to enable integrin-related dual targeting.
- Addresses intrinsic limitations of native collagen (few active residues and non-customizable motifs) for enhanced hemostasis.
Methodological Strengths
- Rational motif engineering on a human collagen scaffold (COL3A1).
- Dual-target design to engage multiple hemostatic pathways.
Limitations
- Abstract does not report in vivo efficacy or safety data.
- Immunogenicity, biodegradation profile, and manufacturability remain to be established.
Future Directions: Validate hemostatic performance in standardized bleeding models, de-risk immunogenicity, and optimize scalable bioprocessing for clinical translation.
Collagen has superior bioactivity in hemostasis but is limited by a few active amino acids and noncustomizable motifs. Here, we propose a biosynthetic strategy to construct multicopy dual-targeted recombinant collagen. Using human collagen type III alpha 1 chain (COL3α1) as a template, we integrated hemostatic motifs GFPGER and GPP, which bind integrin α
2. Senomorphic Activity of a Novel Standardized Propolis Extract in Human Dermal Fibroblasts: Molecular Insights Into Clinically Proven Anti-Wrinkle Efficacy.
Using a validated SIPS model in human dermal fibroblasts, a chemically standardized propolis extract (0.05%) suppressed SASP cytokine IL-6 to a degree comparable to rapamycin, while uniquely upregulating CDK4 and p21. Exploratory SA-β-gal assessments suggested reduced senescence burden, aligning with prior clinical anti-wrinkle efficacy.
Impact: This work provides mechanistic validation for a clinically effective anti-wrinkle active via senomorphic modulation, a promising strategy to target inflammaging without cytotoxicity.
Clinical Implications: Supports evidence-based incorporation of standardized propolis extract into dermocosmetic formulations aimed at reducing inflammaging and improving wrinkle appearance.
Key Findings
- SPE (0.05%) significantly suppressed IL-6 (FC: -7.78, p=0.003), comparable to rapamycin (FC: -8.1, p=0.003).
- SPE uniquely upregulated CDK4 (FC: +6.71, p=0.002) and CDKN1A/p21 (FC: +2.33, p=0.005), not observed with rapamycin.
- Exploratory assays indicated qualitative reduction in SA-β-gal staining, consistent with senomorphic activity.
Methodological Strengths
- Use of a validated SIPS model with a reference senomorphic control (rapamycin).
- Quantitative gene expression with statistical significance reporting.
Limitations
- In vitro-only study; clinical dose-response and long-term effects are not addressed.
- SA-β-gal findings are exploratory and qualitative per abstract.
Future Directions: Extend to ex vivo skin models and controlled clinical studies to link molecular endpoints with wrinkle outcomes and define optimal dosing/regimens.
BACKGROUND: We recently demonstrated in a randomized controlled trial (RCT) that a Standardized Propolis Extract (SPE), produced via a patented non-alcoholic PEG 400/lecithin process, achieves significant clinical anti-wrinkle efficacy (34% wrinkle depth reduction). The present study investigates the underlying molecular mechanisms, specifically its potential senomorphic activity-the ability to modulate the Senescence-Associated Secretory Phenotype (SASP) without inducing cell death. OBJECTIVE: To evaluate the senomorphic activity of this chemically defined SPE (standardized to 1318.43 μg/g total phenolic markers) in an in vitro model of oxidative stress-induced senescence, providing molecular insights into its clinically observed anti-aging effects. METHODS: Human Dermal Fibroblasts (HDFs) were pre-treated with SPE (0.01%, 0.05%) or Rapamycin (3 μM, reference senomorphic control). Senescence was induced via a validated stress-induced premature senescence (SIPS) protocol (200 μM H RESULTS: The 0.05% SPE demonstrated potent senomorphic activity, significantly suppressing the key SASP marker IL-6 (FC: -7.78, p = 0.003)-comparable to the Rapamycin control (FC: -8.1, p = 0.003). Uniquely, SPE induced transcriptional upregulation of CDK4 (FC: +6.71, p = 0.002) and CDKN1A/p21 (FC: +2.33, p = 0.005), effects not observed with Rapamycin. In exploratory MSC experiments, SPE qualitatively reduced SA-β-gal staining. CONCLUSION: This first-in-class standardized propolis extract demonstrates distinct senomorphic activity, suppressing the inflammatory SASP (IL-6) while inducing transcriptional modulation of pro-regenerative pathways (CDK4). These molecular findings provide mechanistic insights consistent with the extract's clinically proven anti-wrinkle efficacy, supporting its positioning as an evidence-based active ingredient for dermo-cosmetic formulations targeting inflammaging.
3. Fibronectin-Based Skin Care Regimens for Skin Recovery After Intense Pulsed Light Therapy: A Split-Face Study.
In a 28-day split-face study (n=32 women), a fibronectin-containing serum significantly improved hydration, reduced TEWL on days 3, 7, and 28, and enhanced radiance while reducing erythema versus control. Dermatologist and participant ratings corroborated objective measures, and no adverse events were reported.
Impact: Demonstrates a pragmatic, well-tolerated post-IPL regimen that improves clinically relevant barrier and erythema endpoints in a controlled split-face design.
Clinical Implications: Supports incorporating fibronectin-containing serums into post-IPL care protocols to expedite barrier recovery and reduce downtime.
Key Findings
- Fibronectin-treated side showed greater hydration improvements versus control (P<0.01).
- TEWL was significantly lower on days 3, 7, and 28 on the fibronectin side (P<0.05 to P<0.01).
- Radiance increased and erythema decreased more on the fibronectin side by days 7 and 28 (P<0.01); no adverse events observed.
Methodological Strengths
- Split-face within-subject control minimizes inter-individual variability.
- Multiple objective endpoints (hydration, TEWL, erythema, radiance) with consistent dermatologist/participant assessments.
Limitations
- Small, single-center cohort of healthy females; generalizability may be limited.
- Randomization/blinding details are not specified; longer-term outcomes beyond 28 days are unknown.
Future Directions: Confirm efficacy in larger, blinded randomized studies, assess diverse skin types and IPL parameters, and evaluate durability beyond 28 days.
PURPOSE: Intense pulsed light (IPL) treatment may cause transient erythema, dryness, and barrier dysfunction, highlighting the need for effective postprocedural care. This study aimed to assess the efficacy and safety of a fibronectin-containing skincare regimen in restoring skin barrier function and relieving these IPL-related manifestations. PATIENTS AND METHODS: In this 28-day, split-face study, 32 healthy female participants undergoing IPL treatment applied a fibronectin-containing serum to one side of the face and a control serum to the opposite side. Skin hydration, transepidermal water loss (TEWL), erythema, and radiance were evaluated at baseline, immediately post-IPL, and on days 3, 7, and 28. RESULTS: Compared to the control, the fibronectin-treated side showed significantly greater improvements in skin hydration (P < 0.01) and significantly lower TEWL on days 3 (P < 0.05), 7 (P < 0.01), and 28 (P < 0.01). By days 7 and 28, skin radiance and erythema also improved more significantly (P < 0.01). Both dermatologist and participant assessments confirmed the superior efficacy of the fibronectin serum. No adverse events were rePorted. CONCLUSION: Post-IPL aPPlication of a fibronectin-containing serum effectively imProves skin hydration, reduces barrier dysfunction and erythema, and enhances radiance with good tolerability. These findings suPPort its Potential utility in Post-IPL skincare regimens.
