Abstract: The invention relates to the field of tumor treatment, in particular to melanoma tumor treatment. In particular it relates to the use of retinoid X receptor antagonists for use in tumor treatment, in particular for use in reducing tumor cell heterogeneity during minimal residual disease (MRD), and thus for use in treating MRD. Even more in particular, the invention relates to the use of retinoid X receptor antagonists in combination with clinically established treatments such as treatment with a combination of BRAF and MEK inhibitors, and optionally other anticancer agents.

Abstract: The invention relates to the field of tumor disease stratification, in particular melanoma disease stratification. In particular it relates to the methods for tumor analysis, such as for determining tumor cell heterogeneity during treatment. These methods are helpful in selecting or optimizing tumor therapy, or in predicting responses to tumor therapy. The invention further relates to methods for screening for cytotoxic or cytostatic compounds targeting one or more of the heterogeneous tumor cell populations occurring such as during therapy, such as during the minimal residual disease phase.

Abstract: The invention relates to the field of tumor treatment, in particular to melanoma tumor treatment. In particular it relates to the use of CD36 antagonists for use in tumor treatment, in particular for use in reducing tumor cell heterogeneity during minimal residual disease (MRD), and thus for use in treating MRD. Even more in particular, the invention relates to the use of CD36 antagonists in combination with clinically established treatments such as treatment with a combination of BRAF and MEK inhibitors, and optionally other anticancer agents.

Abstract: At least one microRNA selected from among hsa-miR-330, hsa-miR-7 and hsa-miR-137, the mature forms thereof, and the precursors thereof, for depigmenting the skin, and an in vitro method for identifying depigmenting compounds, which includes the steps of: a) placing at least one test compound in contact with a sample of melanocytes; b) measuring the expression or activity of at least one microRNA selected from among miR-330, miR-7 and miR-137, the mature forms thereof, and the precursors thereof, in the melanocytes; c) selecting the compounds for which at least 20% activation of the expression or of the activity of at least one of the microRNAs is measured in the melanocytes treated in a) by an element for comparing with the untreated melanocytes.
