- Exosome diameter was measured using a Zetasizer Nano S instrument (Malvern Instruments Ltd., Worcestershire, UK) equipped with a 633 nm laser at 10 ⁇ 30 s scattering intensity.
- Exosomal protein was isolated by SDS-PAGE.
- the SDS-PAGE gel was cut into 10 pieces and known methods (Bahk YY, Kim SA, Kim JS, et al. (2004) Antigens secreted from Mycobacterium tuberculosis: identification by proteomics approach and test for diagnostic marker.Proteomics 4: 3299 -307.) was isolated in gel using trypsin (Promega, Madison, WI, USA). In summary, the gel pieces were washed 4-5 times with 1: 1 acetonitrile (ACN) / 25 mM ammonium bicarbonate (ABC), dehydrated at 100% ACN, and dried. Reduction in 100 mM DTT with 100 mM ABC at 56 ° C.
- ACN acetonitrile
- ABSC ammonium bicarbonate
- the isolated peptide is previously known method (Zuo X, Echan L, Hembach P, et al. (2001) Towards global analysis of mammalian proteomes using sample prefractionation prior to narrow pH range two-dimensional gels and using one-dimensional gels for insoluble and large proteins.Electrophoresis 22: 1603-15.) was analyzed using reversed-phase capillary HPLC directly connected to a Finnigan LCQ ion-trap mass spectrometer (LC-MS / MS).

- protease inhibitors Sigma. Protein concentration was analyzed by BCA assay, samples were separated by SDS-PAGE, transferred to PVDF membrane and analyzed by antibody against CD81 (SBI). Meanwhile, the SDS-PAGE gel was tested by applying to a silver staining kit (Thermo Fisher Scientific, Rockford, IL, USA) according to the manufacturer's instructions for silver staining.
- Melanogenic cells were dispensed in 6-well plates at a density of 1 ⁇ 10 4 cells / well. The following day, 10 ⁇ l of exosomes isolated from the same cell number were treated. Cells were fixed with 4% formaldehyde in PBS for 15 minutes, washed with PBS and stained with 0.1% crystal violet for 20 minutes. After washing with PBS, the cells were dried and lysed with 10% acetic acid. Absorbance was measured at 590 nm using a spectrophotometer.
- the melanocyte-forming cells were irradiated with UVB (20 mJ / cm 2 ) and incubated for 24 hours. As a result, the secretion of exosomes increased upon exposure to UV light.
- the melanocyte-forming cells increase the amount of exosomes released when exposed to ultraviolet rays, and decrease the amount of exosomes released when an exosome generation / secretion inhibitor is added even when exposed to ultraviolet rays.
- melanocyte-derived exosomes exposed to ultraviolet rays increase the viability of melanocytes that are damaged by UV rays, and exosomes released from melanocytes upon UV irradiation inhibit the apoptosis of melanocytes. It was found to have.
- the substance that inhibits or increases the release of exosomes from melanocytes can regulate melanin production by promoting apoptosis of melanocytes (exhaust inhibitor) or reducing (exhaust increase substance).
- GW4869 or pifithrin- ⁇ 50mg, L-carnitine 80-140mg, soybean oil 180mg, palm oil 2mg, vegetable hardened oil 8mg, lead 4mg and lecithin 6mg was mixed and 400mg per capsule was prepared according to a conventional method to prepare a soft capsule. .
- Tablets were prepared by mixing GW4869 or pifithrin- ⁇ 50 mg, galactooligosaccharide 200 mg, lactose 60 mg and malt 140 mg, granulating using a fluidized bed dryer, and then adding 6 mg of sugar ester to a tablet press.
- the lotion was prepared in a conventional manner according to the composition described in Table 1 below.
