1. Targeting the glabellar frown lines with OnabotulinumtoxinA: In-silico evidence supporting concentrated, low-volume injection protocols.
A multiscale, in-silico model suggests that concentrated, low-volume BoNT-A injections for glabellar lines increase receptor engagement, limit off-target diffusion, and may extend duration to ~125 days. The model integrates tissue diffusion, receptor PK/PD, and ML risk prediction across 20,000 virtual patients, indicating substantial variability under fixed-dose protocols.
Impact: It introduces a first-of-its-kind mechanistic simulation of dose–volume interactions for BoNT-A in 3D facial anatomy, offering a data-driven rationale for precision dosing.
Clinical Implications: Supports exploring low-volume, concentrated BoNT-A glabellar protocols to improve durability and precision, and motivates prospective trials and personalized dosing algorithms.
Key Findings
- Concentrated, low-volume dosing increased modeled SV2 receptor occupancy up to 93.7% and confined diffusion to target muscles.
- Simulated clinical duration extended to 124.7 days, exceeding conventional protocols.
- Exposure and efficacy varied by 30–70% between fixed-dose label protocols and weight-adjusted regimens in the synthetic population.
Methodological Strengths
- Multiscale integration of finite element diffusion, receptor-specific PK/PD, and machine learning risk modeling
- Large synthetic cohort (n=20,000) enabling population-level variability assessment
Limitations
- In-silico study with synthetic data; lacks prospective clinical validation
- Model assumptions may affect translatability to real-world patients
Future Directions: Prospective randomized trials comparing low-volume, concentrated dosing vs standard protocols; model refinement with clinical pharmacodynamic data to build personalized dosing tools.
2. The Impact of an AGE-Inhibiting Moisturizer on Procedure Effectiveness.
In a randomized, double-blind, split-face trial of 42 women across all Fitzpatrick skin types, an AGE-inhibiting moisturizer improved multiple skin attributes after resurfacing procedures versus a bland control. Benefits included greater improvements in clarity, tone evenness, fine lines, elasticity, and overall appearance at week 8, with good tolerability.
Impact: Provides controlled clinical evidence that an AGE-targeted adjunct enhances post-resurfacing outcomes across diverse skin tones, informing peri-procedural care.
Clinical Implications: Consider incorporating AGE-inhibiting moisturizers into post-resurfacing regimens (RFMN or chemical peels) to improve recovery and treatment outcomes, with monitoring across skin types.
Key Findings
- After glycolic acid peel in Fitzpatrick III–VI, the AGE-inhibiting moisturizer side showed greater improvement at week 8 in clarity, tone evenness, fine lines, elasticity, and overall appearance (all P<0.05).
- Ten attributes improved from baseline on the AGE-inhibiting side, including wrinkles, firmness, radiance, clarity, and hyperpigmentation.
- After RFMN in Fitzpatrick I–II, the AGE-inhibiting side had greater improvements in laxity, clarity, fine lines, elasticity, and overall appearance at week 8 versus control (all P<0.05).
Methodological Strengths
- Randomized, double-blind, split-face controlled design
- Inclusion of diverse Fitzpatrick skin types with standardized imaging (VISIA)
Limitations
- Single-site study with a modest sample size and female-only participants
- Different procedures by skin type (RFMN vs glycolic peel) may limit cross-procedure generalizability
Future Directions: Multicenter trials with larger, gender-balanced cohorts; head-to-head comparisons across procedures; mechanistic biomarkers to link AGE inhibition to matrix remodeling.
3. The ceRNA Regulatory Network in Vitiligo: Evidence from Bioinformatics Analysis.
Bioinformatics integration of GEO datasets mapped a vitiligo-associated lncRNA–miRNA–mRNA ceRNA network, highlighting melanogenesis, oxidative stress, PI3K–Akt, JAK–STAT, and IL-17 signaling. Seven circulating lncRNAs were validated in blood, suggesting noninvasive diagnostic potential.
Impact: Defines a systems-level ceRNA landscape in vitiligo and validates circulating lncRNAs, bridging discovery bioinformatics with translational diagnostics.
Clinical Implications: Circulating lncRNAs could complement clinical evaluation as noninvasive biomarkers; pathway insights inform target discovery for future therapies.
Key Findings
- Identified 454 DE-mRNAs, 22 DE-miRNAs, and 281 DE-lncRNAs in vitiligo versus controls.
- Enrichment implicated melanogenesis, oxidative stress, PI3K-Akt, JAK-STAT, and IL-17 signaling pathways.
- Constructed a ceRNA network (33 lncRNAs, 12 miRNAs, 58 mRNAs); hub proteins included SLC32A1, GRIA2, PRKACG, and WNT1.
- Blood validation confirmed up-regulation of CASC19, NUCB1-AS1, LINC01485 and down-regulation of VAV3-AS1, SPATA13-AS1, ZNF350-AS1, LINC00677.
Methodological Strengths
- Integration of multi-omic datasets with pathway enrichment and network analysis
- External blood validation of candidate lncRNAs to support translational potential
Limitations
- Reliance on public datasets with unspecified sample sizes and potential batch effects
- Cross-sectional bioinformatics without prospective diagnostic performance metrics or functional validation
Future Directions: Prospective, multicenter validation of lncRNA panels with ROC-based diagnostics; functional studies to probe ceRNA interactions and therapeutic targeting.
