A rare punctate palmoplantar keratoderma characterized by multiple small, round to oval or rhomboid, yellowish, hyperkeratotic papules and plaques most commonly localized to the palms of the hands and soles of the feet, potentially extending to the dorsum of the hands and feet in severe cases. Histopathological analysis shows hyperkeratosis, epidermal hypertrophy, and fragmentation and rarefaction of elastic fibers. The condition can be sporadic or familial.
Metformin activates AMPK leading to mTOR inhibition and autophagy enhancement in keratinocytes. This reduces abnormal keratin accumulation through increased autophagosome formation and promotes normal epidermal turnover via ULK1 and Beclin-1 upregulation.
Selective HDAC6 inhibition restores normal keratinocyte differentiation by enhancing α-tubulin acetylation and promoting proper microtubule-mediated transport of differentiation factors including involucrin and filaggrin to the cell periphery.
Dual targeting of lysyl oxidase (LOX) upregulation and matrix metalloproteinase (MMP-2, MMP-9) inhibition to restore elastin crosslinking and prevent degradation. Quercetin activates SIRT1-mediated LOX expression while resveratrol inhibits NF-κB-driven MMP transcription.
Asiaticoside from Centella asiatica upregulates filaggrin (FLG) and loricrin (LOR) expression via STAT3 activation. Withanoside IV from Withania somnifera enhances ceramide synthesis through SPTLC1/SPTLC2 upregulation and reduces keratinocyte hyperproliferation.
Development of elastin peptide biomarker (VGVAPG repeats) detection system coupled with targeted delivery of recombinant lysyl oxidase-like 1 (LOXL1) enzyme using elastin-binding peptide carriers to specifically restore crosslinking in affected areas.
Tanshinone IIA from Salvia miltiorrhiza (Danshen) inhibits TGF-β1/Smad3 signaling while promoting Nrf2-mediated antioxidant response. Combined with traditional Si Wu Tang components to enhance microcirculation and regulate COL1A1/COL3A1 expression ratios.
Paeoniflorin from Paeonia suffruticosa inhibits IL-17A/IL-22 signaling while promoting PPAR-γ activation in keratinocytes. Combined with Ephedra sinica alkaloids to enhance peripheral circulation and reduce local inflammation through β2-adrenergic receptor modulation.
