| Origin of Peptide | Synthetic (by conjugating TD1 (ACSSSPSKHCG) and (oligoarginine) R8 ) | |
| Nature of Peptide/Cargo | MITF-siRNA inhibition of melanin synthesis and melanoma cell apoptosis. | |
| Mechanism | MITF-siRNA-silenced MITF gene expression effectively induced a significant reduction in tyrosinase (TYR), tyrosinase-related protein 1, and melanocortin 1 receptor (MC1R) levels. | |
| Cargo Sequence/Structure | MITF-siR: sense 5′-GCAGUACCUUUCUACCACUTT-3′ | |
| Name of cargo | Microphthalmia-associated transcription factor–siRNA (MITF-siR) | |
| Assay | Laser scanning confocal microscopy | |
| Enhancer | Hair clipped mice skin | |
| Properties of enhancer | Not applicable | |
| Concentration | 100 µg of cream containing 0.005% MITF-siR and arginine-rich peptide (TD1-R8). | |
| Incubation time | 2 hours | |
| Tissue permeability (value with units) | Significant penetration of carboxyfluorescein-labeled MITF-siR can be seen in confocal images of whole epidermis and partial dermis | |
| Tissue Sample | Hair shaved back of BALB/c mice | |
| Ex vivo/In vivo/In vitro | ex vivo | |
