TretinoinVitamin WellAcitretinIsotretinoinKeratolytic: Keratolytic therapy is treatment to remove warts and other lesions in which the epidermis produces excess skin. In this therapy, acid medicine, such as salicylic acid is put on the lesion.Retinol binding protein 4: Retinol binding protein 4, plasma, also known as RBP4, is a protein that in humans is encoded by the RBP4 gene.MotretinideTamibaroteneFenretinidePropyl benzoateBeta-carotene 15,15'-dioxygenase: Beta-carotene 15,15'-dioxygenase (, blh (gene)) is an enzyme with system name beta-carotene:oxygen 15,15'-dioxygenase (bond-cleaving). This enzyme catalyses the following chemical reactionTazaroteneMinC: The MinC protein is one of three proteins encoded by the minB operon and which is required to generate pole to pole oscillations prior to bacterial cell division as a means of specifying the midzone of the cell. This function is achieved by preventing the formation of the divisome Z-ring around the poles.Beta-carotene 3-hydroxylase: Beta-carotene 3-hydroxylase (, beta-carotene 3,3'-monooxygenase, CrtZ) is an enzyme with system name beta-carotene,NADH:oxygen 3-oxidoreductase . This enzyme catalyses the following chemical reactionRetinol binding protein: Retinol-binding proteins (RBP) are a family of proteins with diverse functions. They are carrier proteins that bind retinol.Skin flora: The skin flora, more properly referred to as the skin microbiota, are the microorganisms which reside on the skin. Most research has been upon those that reside upon the 2 square metres of human skin, cf.Isomerization: In chemistry isomerization (also isomerisation) is the process by which one molecule is transformed into another molecule which has exactly the same atoms, but the atoms have a different arrangement e.g.Orange carotenoid N-terminal domain: In molecular biology the orange carotenoid N-terminal domain is a protein domain found predominantly at the N-terminus of the Orange carotenoid protein (OCP), and is involved in non-covalent binding of a carotenoid chromophore. It is unique for being present in soluble proteins, whereas the vast majority of domains capable of binding carotenoids are intrinsic membrane proteins.Pituitary-specific positive transcription factor 1: POU domain, class 1, transcription factor 1 (Pit1, growth hormone factor 1), also known as POU1F1, is a transcription factor for growth hormone.Hypervitaminosis DMature messenger RNA: Mature messenger RNA, often abbreviated as mature mRNA is a eukaryotic RNA transcript that has been spliced and processed and is ready for translation in the course of protein synthesis. Unlike the eukaryotic RNA immediately after transcription known as precursor messenger RNA, it consists exclusively of exons, with all introns removed.Antileukemic drug: Antileukemic drugs, anticancer drugs that are used to treat one or more types of leukemia, include:Quinupramine
