1. Role of SLC16A10 in Psoriasis Through the Regulation of Arachidonic Acid Metabolism in Keratinocytes.
Through RNA-seq prioritization and multi-system validation, SLC16A10 emerges as a regulator of keratinocyte arachidonic acid metabolism via thyroid hormone homeostasis, driving psoriatic inflammation. Downregulating SLC16A10 ameliorates disease severity in vitro and in vivo and may influence post-inflammatory hypopigmentation by suppressing melanogenesis.
Impact: Identifies a metabolically anchored, mechanistically validated target (SLC16A10) linking thyroid hormone, lipid metabolism, and psoriatic inflammation, opening therapeutic avenues beyond immune-only strategies.
Clinical Implications: Positions SLC16A10 as a candidate biomarker and therapeutic target for psoriasis, potentially complementing current immune-targeted therapies and informing combination approaches.
Key Findings
- SLC16A10 was identified as a differentially expressed metabolism-related gene with diagnostic and therapeutic potential in psoriasis.
- Functional experiments showed that downregulating SLC16A10 reduced psoriatic hyperinflammation and disease severity in vitro and in vivo.
- Mechanistically, SLC16A10 likely modulates keratinocyte arachidonic acid metabolism via thyroid hormone homeostasis and may also inhibit melanogenesis, contributing to post-inflammatory hypopigmentation.
Methodological Strengths
- Integrated RNA-seq, bioinformatics, and both in vitro and in vivo functional validation.
- Mechanistic linkage across endocrine-metabolic-dermatologic axes (thyroid hormone–lipid metabolism–keratinocyte biology).
Limitations
- Preclinical focus with no randomized human clinical data.
- Generalizability to diverse psoriasis subtypes and human tissue heterogeneity remains to be established.
Future Directions: Validate SLC16A10 as a biomarker in clinical cohorts; develop and test pharmacologic or genetic modulators in psoriasis models; explore synergy with current biologics.
2. Fractional CO2 Versus Radiofrequency as Hair Regrowth Enhancers for Female Androgenic Alopecia: A Randomized Controlled Trial.
In a randomized, two-arm, split-side design with 30 women, both FCO2 and FMRF enhanced outcomes when added to topical 5% minoxidil, but FMRF produced greater gains in trichoscopic hair counts and density. Tolerability was favorable, supporting FMRF as a superior adjuvant to minoxidil for female pattern hair loss.
Impact: Provides comparative RCT evidence favoring fractional microneedling radiofrequency over fractional CO2 as an adjuvant to minoxidil in female pattern hair loss.
Clinical Implications: Supports choosing FMRF over FCO2 when augmenting minoxidil in female pattern hair loss, pending larger, blinded trials to confirm durability and safety.
Key Findings
- All treatment modalities (minoxidil alone, minoxidil+FCO2, minoxidil+FMRF) increased trichoscopic hair counts and density.
- Minoxidil+FMRF produced significantly greater increases in hair counts and density than minoxidil+FCO2 or minoxidil alone.
- Randomization and side-specific treatment allowed within-patient comparison of device effects.
Methodological Strengths
- Randomized allocation with split-side scalp treatment enabling intra-individual control.
- Objective trichoscopic endpoints (hair counts and density).
Limitations
- Small sample size (n=30) with short-term assessment and unclear blinding.
- No long-term durability or safety outcomes reported.
Future Directions: Conduct larger, blinded RCTs with standardized protocols, longer follow-up, and patient-reported outcomes to confirm superiority and safety of FMRF.
3. Efficacy of Intense Pulsed Light AOPT-LTL Technique in the Treatment of Melasma: An In Vivo and Clinical Study.
AOPT-LTL IPL reduced pigmentation, inflammation, angiogenesis, mast cell infiltration, and collagen degradation in a guinea pig melasma model, concomitant with suppression of SCF/c-KIT signaling. In 20 patients, three monthly sessions lowered melanin and erythema with improved mMASI and EI scores.
Impact: Links a specific IPL delivery mode to multi-pathway biological effects and clinical improvement in melasma, providing mechanistic rationale (SCF/c-KIT inhibition) for protocol optimization.
Clinical Implications: Supports low-energy triple-pulse long-width IPL as a viable option for melasma with concurrent anti-inflammatory and anti-angiogenic effects; parameterization may reduce rebound and adverse effects.
Key Findings
- In vivo AOPT-LTL IPL decreased pigmentation and downregulated melanogenic enzymes, inflammatory mediators, and pro-angiogenic factors.
- AOPT-LTL reduced mast cell infiltration and suppressed SCF/c-KIT signaling, a pathway linked to mast cell activation.
- In 20 patients, three monthly AOPT-LTL sessions reduced melanin content and erythema, improving mMASI and EI scores.
Methodological Strengths
- Translational design integrating mechanistic in vivo work with clinical patient outcomes.
- Multi-omic readouts (qRT-PCR, immunofluorescence/Western blot) to map pathway effects.
Limitations
- Clinical arm is an uncontrolled small case series (n=20) with short follow-up.
- Generalizability across Fitzpatrick skin types and relapse prevention not established.
Future Directions: Randomized, controlled trials comparing AOPT-LTL with other IPL parameters and lasers; biomarker-guided personalization targeting SCF/c-KIT and angiogenesis.
