Abstract: The present invention relates to a method for the in vitro prognosis and/or diagnosis of a common alopecic state of the scalp in a subject, comprising at least one step a) of measuring the expression level, in a biological sample from an area suspected of being an alopecic area or of becoming an alopecic area in said subject, of at least one gene involved in the intercellular junctions of the scalp and/or of the hair follicle chosen 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 chosen from CTNNB1 and CTNND2, wherein said common alopecic state is chosen from androgenetic alopecia, traction alopecia, female pattern hair loss, cicatricial alopecia, telogen effluvium, stress-related alopecia, seasonal alopecia, age-related alopecia and micro-inflammatory alopecia.

Abstract: The present invention relates to a method of prognostic of the survival of human subject suffering from chronic myelomonocytic leukemia (CMML) based on the differential expression of six genes in a test sample of PBMC cells obtained from said human subject and in a control sample of normal cells, wherein said expression level indicates if the human subject from which the test sample has been obtained will have long-term or short-term survival.
