AVERTISSEMENT : Le chatbot Graph n'est pas programmé pour fournir des réponses explicites ou catégoriques à vos questions. Il transforme plutôt vos questions en demandes API qui sont distribuées aux différents services informatiques officiellement administrés par l'EPFL. Son but est uniquement de collecter et de recommander des références pertinentes à des contenus que vous pouvez explorer pour vous aider à répondre à vos questions.
We have isolated a cDNA corresponding to the hamster peroxisome proliferator-activated receptor haPPAR gamma, a member of the steroid nuclear hormone receptor superfamily of transcription factors. haPPAR gamma mRNA is highly expressed in adipose tissue, an ...
Transcriptional activity relies on coregulators that modify chromatin structure or serve as bridging factors between transcription factors and the basal transcription machinery. We identified a new coregulator of peroxisome proliferator-activated receptor ...
Our recent studies have demonstrated that PPARalpha activators stimulate differentiation and inhibit proliferation in cultured human keratinocytes and accelerate epidermal development and permeability barrier formation in fetal rat skin explants. As the ro ...
Sterols and cholesterol in particular are lipids that have been studied exhaustively in view of their vital role in diverse cellular functions. Recently, it has been recognized that cholesterol is not only an essential component for the formation of membra ...
CCAAT/enhancer-binding protein (C/EBP) family members are transcription factors involved in important physiological processes, such as cellular proliferation and differentiation, regulation of energy homeostasis, inflammation, and hematopoiesis. Transcript ...
The protective function of the skin is mediated by the stratum corneum, the outermost layer of the skin, which is the end-product of epidermal differentiation. Previously, we showed that fetal rat skin explants complete the late-stage milestones of epiderm ...
The three types of peroxisome proliferator-activated receptors (PPAR), termed alpha, delta (or beta), and gamma, belong to the nuclear receptor superfamily. Although peroxisome proliferators, including fibrates and fatty acids, activate the transcriptional ...
Intracellular and extracellular cholesterol levels are tightly maintained within a narrow concentration range by an intricate transcriptional control mechanism. Excess cholesterol can be converted into oxysterols, signaling molecules, which modulate the ac ...
The recessive mouse mutation kreisler affects hindbrain segmentation and inner ear development in homozygous mice. The mouse gene affected by the mutation was found to encode a basic domain leucine-zipper (bZIP)-type transcription factor of the Maf-family ...
Members of the nuclear receptor family are involved in an increasing number of processes in the cell. These receptors can directly regulate gene expression by binding to DNA. The molecular basis for transcriptional activation is so far not well understood. ...
