EpigénétiqueL'épigénétique (mot-valise de "épigenèse" et "génétique") est la discipline de la biologie qui étudie la nature des mécanismes modifiant de manière réversible, transmissible (lors des divisions cellulaires) et adaptative l'expression des gènes sans en changer la séquence nucléotidique (ADN)
"Alors que la génétique correspond à l'étude des gènes, l'épigénétique s’intéresse à une "couche" d’informations complémentaires qui définit comment ces gènes vont être utilisés par une cellule ou… ne pas l'être".
"C'est un concept qui dément en partie la "fatalité" des gènes".

| Résumé : |
To explore the field of epigenetics in greater detail, BASF researchers have joined forces and established an interdisciplinary innovation platform. Together with experts from public and private research institutions, they are exploring how modulations to our gene expression, caused by either chronological aging or environmental factors, can be mapped and controlled. New anti-aging active ingredients harness the platform's findings. Dermagenist®, an extract of Origanum majorana leaves, is the first active ingredient that re-activates fibroblasts by protecting them from epigenetic modifications and stimulating their vitality through LOXL1 promoter re-activation. A clinical study demonstrated an 18 % improvement in skin density after tvvo months of application, and a 15% improvement in skin firmness after three months. RNAge®, an extract of Hippophae rhamnoides seeds, fights chronological microRNA Let-7b dysregulation. Researchers has demonstrated that Let-7b is involved in epigenetic regulation and the balancing of proteins in both the extracellular matrix and the proteoglycan network required for a well-balanced dermal structure. RNAge inhibited Let-7b expression by 39 % versus the untreated control. The skin rebuilds from deep within, recovering its density (+26%) and firmness (+18.5%) for a healthy and youthful appearance. |
