Definitions
- the present invention provides compositions for reducing the synthesis of melanin pigments in melanocytes and uses thereof.
- pigmentation results from the synthesis and distribution of melanin pigments, especially in the skin, hair and fur and the pigment epithelium of the iris.
- the color of the skin, hair and eyes depend mainly on the types of pigments present and their concentrations. This pigmentation is regulated by many internal or external factors, for example, exposure to ultraviolet.
- Melanins are macromolecules produced by melanocytes by addition or condensation of monomers formed from tyrosine (eumelanin) or tyrosine and cysteine (pheomelanin).
- the mechanism of melanin synthesis, or melanogenesis, is particularly complex and involves different enzymes, the main ones being tyrosinase and tyrosine-associated protein (Tyrp-1).
- these enzymes catalyze, in particular, the conversion of tyrosine to DOPA (dihydroxyphenylalanine) and then to DOPAquinone. From this molecule, two metabolic pathways will allow the synthesis of either eumelanin or pheomelanin.
- melanosomes are among the first cellular organelles to be described morphologically (Seiji et al., 1963), their protein composition and biogenesis remain relatively unknown.
- Stage I corresponds to a compartment delimited by a membrane with a variable quantity of intraluminal membranes.
- Stage II is an ellipsoidal structure with characteristic striations of a protein nature. These striations play an important role in the concentration of melanin, in the elimination of toxic synthetic intermediates and in facilitating the transfer of melanin to keratinocytes (Seiji et al., 1963). Melanin is detected from stage III and in the form of electron-dense deposits along the striations.
- Stage IV is an electron-dense structure in which internal striations are no longer visible. This stage corresponds to the mature melanosome ready to be transferred to the keratinocytes (Van
- the "pigmented" mature melanosome (stage III and IV) is obtained by adding key enzymes of melanin synthesis and effectors necessary for its transport to the periphery (Raposo et al., 2001) .
- the enzymes involved in melanogenesis are therefore synthesized in the Golgi apparatus and transferred to pre-melanosomes.
- the mechanisms involved in this transfer are still relatively unknown.
- This type of transfer requires, in particular, the participation of adaptive protein complexes (APs) which are heterotetramers whose role is to recruit the enzymes into the transport vesicles.
- AP-I to AP-4 There are four of these complexes.
- the inventors have previously demonstrated that the AP-3 complex is involved in the transfer of tyrosinase to melanosomes.
- AP-3 deficiency does not abolish pigmentation and does not affect Tyrp-1 trafficking.
- the AP-I adapter complex was able to interact with amino acid sequences of the tyrosinase and Tyrp-1 cytosolic domains without elucidating the exact function of this complex in melanogenesis (Theos and al., 2005).
- Kif13A a kinesin, named Kif13A, is able to interact with an AP-I subunit. This interaction was observed in cell lines lacking a melanosome. The existence of such interaction in melanocyte lineages as well as its role in melanogenesis are therefore not determined.
- Malfunction of melanocytes may cause pigmentation abnormalities. Hypopigmentation can be caused by depigmenting diseases, especially albinism and vitiligo. Conversely, local hyperpigmentations may result from certain melanocytic disorders such as idiopathic melasmas or hyperactivity and benign melanocyte proliferation causing, for example, senile pigment spots (actinic lentigo). Hyperpigmentation can also be of accidental origin and caused for example by photosensitization or post-injury healing. These hyperpigmentations can be treated with depigmenting substances administered topically. A depigmenting molecule acts on the melanocytes of the epidermis and interferes with one or more stages of melanogenesis.
- depigmenting substances include hydroquinone and its derivatives, ascorbic acid and its derivatives, placental extracts, kojic acid, arbutin, iminophenols (WO 99/22707), the combination of carnitine and quinone (DE 19806947), amide derivatives of amino phenol (FR 2 772 607), and benzothiazole derivatives (WO 99/24035).
- WO 99/25819 discloses oligonucleotides used to increase pigmentation by regulating the expression of tenascin to treat vitiligo and other depigmenting diseases and FR 2 804 960 discloses antisense oligonucleotides for regulating the expression of expression of tyrosinase or Tyrp-1 to treat hyperpigmentations.
- the object of the present invention is to provide novel non-toxic, non-irritating, non-allergenic depigmenting agents having specific action on melanogenesis and stable in formulations suitable for topical administration.

- a nucleic acid blocking the expression of a subunit of the AP-I adapter complex or a kinesin interacting with AP-I in the melanocytes.
- the present invention relates, first of all, to a pharmaceutical or cosmetic composition
- a pharmaceutical or cosmetic composition comprising at least one kinesin inhibitor interacting with the AP-I adapter complex, in particular Kif13A, a subunit inhibitor of AP-I adapter complex, or an inhibitor of the interaction between a subunit of the AP-I adapter complex or the AP-I complex and a kinesin interfering therewith.
- API refers to the AP-I adapter complex that is involved in the trans-Golgi network. It should not be confused with the transcription factor of the same name which consists of proteins encoded by genes members of jun and fos families.
- the AP-I adapter complex is composed of 4 subunits: ⁇ , ⁇ 1, ⁇ 1 and ⁇ 1, and activation of any one of these subunits is sufficient to destabilize the complex and render it inoperative (Braun, 2007).

- the inhibitor is an aptamer, an antibody, a nucleic acid or a dominant negative peptide.
- the term "dominant negative peptide" refers to a peptide comprising at least a portion of a kinesin interacting with AP-I and capable of suppressing or decreasing its activity.
- the dominant negative peptide consists only of the part of the kinesin interacting with AP-I, that is to say the part corresponding to the tail of kinesin. This peptide is therefore capable of interacting with the AP-I complex but, in the absence of the corresponding to the head of kinesin, is unable to move along the microtubules and thus to fulfill its function.
- Kif13A Several dominant peptides negative for kinesin Kif13A have already been described. In particular, a dominant negative peptide of Kif13A was obtained by expressing only the portion of the Kif13A protein corresponding to the tail of kinesin (Nakagawa et al., 2000).
- the kinesin inhibitor is a nucleic acid comprising or consisting of a sequence capable of specifically hybridizing with a gene or mRNA encoding kinesin interacting with AP-I, in particular Kifl3A, and decrease or suppress the expression of this protein.

- the lysates were then centrifuged at 4000 rpm and the supernatants were collected and then incubated with washed beads which had been incubated for 1 h with 1 ⁇ g of rabbit antibody (Kifl3A control) or mouse anti-CD9 ( ⁇ control AP-1 adaptin). Immunoprecipitation is then carried out by centrifuging the lysates at 4000 rpm and bringing the supernatants into contact with 20 ⁇ l of washed beads previously incubated for 2 h at 4 ° C. under rotation with 1 ⁇ g of rabbit antibody (Kifl3a control).
- the melanocyte cells previously seeded in 6-well dishes and treated with "control" siRNAs and siRNA-Kifl3A or siRNA- ⁇ lA were fixed either with a mixture of 2% PFA and 2% glutaraldehyde (conventional microscopy) or a mixture 2% PFA and 0.5% glutaraldehyde (immunolabeling) in 0.2 M phosphate buffer pH 7.4 for 4 hours at room temperature.
- the cell pellets were first coated in 10% gelatin. After solidification at 4 ° C., 1 mm 3 blocks were cut and infused in 2.3M sucrose for 2 hours. The cell blocks were frozen on their support and ultrafine frozen sections were made with an ultracryo micro volume (Leica ® , Austria). Sections recovered on electron microscopy grids were immunostained with anti-Tyrpl and anti-Pmell7 antibodies. These antibodies were visualized with protein A coupled to colloidal gold particles. The sections were contrasted and embedded in a mixture of uranyl acetate and methylcellulose before observation under an electron microscope (Phillips CM120, FEI Company ® ). Imaging was performed with a KeenView camera (SIS ® , Germany). Quantification of melanin
- the cells were washed twice in PBS and incubated with 150 ⁇ l of melanine buffer (50 mM Tris, 2 mM EDTA, 150 Mm NaCl, 1% protease inhibitor, pH 7 4). They were then scraped and grouped in a single fraction before being sonicated for 20 seconds at maximum intensity. 10 ⁇ L were then taken to quantify the proteins (with the BCA Protein Assay kit, Pierce) and 200 ⁇ g of proteins were removed and centrifuged at 15,000 rpm for 15 min at 4 ° C.

Once solubilized, 200 ⁇ L was taken to measure the optical density at 492 nm.
- melanine buffer 50 mM Tris, 2 mM EDTA, 150 Mm NaC
- Quantification was performed on cells prepared for immunofluorescence using an epifluorescence microscope. The cells were observed in phase contrast and the presence (black) or absence (white) of pigmented mature melanosomes was quantified.
- the relative amount of melanin in melanocytes transfected with siRNA-Kif13A compared to the amount present in cells transfected with siRNA control was determined by measuring the optical density of the cell lysate at a wavelength of 492 nm ( Figure 2).
- the results presented in Figure 2 show that the use of siRNA-Kifl3A made it possible to obtain a reduction in the amount of melanin synthesized of the order of 40% compared to the cells transfected with the siRNA-control.
- Electron microcopy observations were performed on melanocytes transfected with siRNA-Kif13A or siRNA-control either by conventional electron microscopy (FIG. 3) or with immunolabeling with anti-Tyrpl antibodies (data not shown). .
- melanocytes transfected with siRNA-control contained numerous melanosomes with large amounts of melanin (black in Figure 3).
- melanocytes transfected with RNsi-Kifl3A contained little or no pigments.
- melanocytes containing pigmented mature melanosomes the amount of melanocytes containing pigmented mature melanosomes and the proportion of mature melanosomes (stage III or IV) in the melanocytes.
- FIGS. 5A, 5B and 6 show the results obtained on the melanocytes transfected with a siRNA control, an siRNA-1 ⁇ A, an siRNA- ⁇ -adaptin or an siRNA-1 ⁇ A and siRNA- ⁇ -adaptin combination. The results presented in FIGS.
- FIG. 5A and 5B show that the use of siRNA-1 ⁇ A, siRNA- ⁇ -adaptin (FIG. 5A) or both simultaneously (FIG. 5B) made it possible to significantly increase the proportion of white cells among the transfected melanocytes, compared with those transfected with the siRNA-control. This increase reached even 24% for cells transfected with siRNA-l ⁇ A alone.
- FIG. 6 shows that transfection of siRNA-1 ⁇ A, siRNA- ⁇ -adaptin or both simultaneously made it possible to significantly reduce the amount of melanin synthesized in the cells by comparison. with those transfected with siRNA-control. This decrease could reach more than 40% in cells transfected with siRNA-l ⁇ A.
- melanocytes transfected with the siRNA-control contained numerous melanosomes with large amounts of melanin (black in Figure 7). In contrast, melanocytes transfected with siRNA- ⁇ lA contained little or no pigment.
- the inventors have therefore demonstrated that the subunit-specific siRNAs of the AP-I adapter complex have a significant effect on the production of melanin pigments and can therefore be effectively used as depigmenting agents.
