Molecular signature of a common alopecia state, associated with
cell junctions. The present invention relates to a method for the
in vitro prognosis and / or diagnosis of a common alopecia state of the
scalp in a subject, in particular androgenetic alopecia, comprising at least one step a) of measuring the level of expression, in a biological sample taken from an area suspected of being an alopecia area or of becoming an alopecia area in said subject, of at least one
gene selected from CDH1, ACTB, ACTBL2, TUBB, TUBB2A, GSN, MYO3B, MYO5B, MYO6, DSG2, DSG3, DSG4, DSC2, GJB2, GJA1, GJB6, GJA3, TJP2, CLDN8, CLDN10, CLDN19, and optionally of at least one
gene selected from CTNNB1 and CTNND2.The invention also relates to an
in vitro method for evaluating the effectiveness of a treatment for a common alopecia condition, a cosmetic treatment method, the use of a modulator of said
gene(s) mentioned above, as well as a method for identifying a compound enabling the prevention and / or treatment of a common alopecia condition.
