The present invention relates to the use for enhancing Notch signaling in an individual, of a compound showing the general formula (I) and/or a pharmaceutically acceptable salt or ester thereof, for the treatment of a disease selected from the group of der ...
Melanocytes respond to UVR not only by producing melanin, but also by proliferating. This is essentially a protective response. We have studied the melanocyte proliferative response after a single UVR exposure to neonatal mice. At 3 days post-UVR in wild-t ...
Background: Photodynamic therapy (PDT) with Metvix® is a good therapeutic option to treat actinic keratosis, but it presents drawbacks (pain, lesion recurrences, heterogeneous outcome), emphasizing the possible need to individualize treatment. Objective: W ...
Phosphate and tensin homologue deleted on chromosome 10 (PTEN) is a tumor suppressor gene inactivated in numerous sporadic cancers, including melanomas. To analyze Pten functions in melanocytes, we used the Cre-loxP system to delete Pten specifically in mu ...
To examine the consequences of repressing beta-catenin/Lef1 signalling in mouse epidermis, we expressed a DeltaNLef1 transgene, which lacks the beta-catenin binding site, under the control of the keratin 14 promoter. No skin abnormalities were detected bef ...
The aim of this thesis is to optimize and obtain fundamental information on i) the photodetection (PD) of early stage cancers in the tracheo-bronchial tree by spectroscopic imaging of the tissue autofluorescence, ii) photodynamic therapy (PDT) applied in d ...
The Notch signaling pathway is involved in diverse biological processes such as cell fate decisions or stem cell maintenance. In this study, we assessed the role of this pathway for melanocyte development and hair pigmentation using RBP-Jkappa, Notch1, and ...
