Retinoids, a group of structural and functional derivatives of vitamin A are known to regulate a large number of essential biological processes such as cell growth, differentiation and death. The retinoic acid (RA) signalling pathway involves the precise regulation of retinoid levels and the control of RA-dependent gene expression in target cells.

Retinoic acid and its receptors
The American Journal of Surgery, 1993Retinoic acid (RA)--the active metabolite of vitamin A--and its analogues have pleiotropic effects on growth, differentiation, proliferation, and development. RA, and its analogues, determine embryonic pattern formation and inhibit tumor growth; however, they are also teratogens.

Transcriptional Activities of Retinoic Acid Receptors
2005Vitamin A derivatives plays a crucial role in embryonic development, as demonstrated by the teratogenic effect of either an excess or a deficiency in vitamin A. Retinoid effects extend however beyond embryonic development, and tissue homeostasis, lipid metabolism, cellular differentiation and proliferation are in part controlled through the retinoid ...

Retinoic Acid Nuclear Receptors [PDF]
, 1991 The pleiotropic effects that RA exerts during vertebrate development have been studied in a number of experimental systems. For example, retinoic acid (RA) is thought to be the morphogen released by the zone of polarizing activity (ZPA) in the developing chick limb bud (see Smith et al., 1989) for review, and also several other articles in the present ...

Retinoids, a class of hydrophobic compounds including retinol (vitamin A), retinoic acid (RA) and a series of natural and synthetic derivatives, exhibit a vast array of profound and diverse effects on vertebrate development from early embryogenesis to maturity.

Retinoids, Retinoic Acid Receptors, and Cancer
Annual Review of Pathology: Mechanisms of Disease, 2011Retinoids (i.e., vitamin A, all-trans retinoic acid, and related signaling molecules) induce the differentiation of various types of stem cells. Nuclear retinoic acid receptors mediate most but not all of the effects of retinoids. Retinoid signaling is often compromised early in carcinogenesis, which suggests that a reduction in retinoid signaling may ...

Altered retinoic acid receptors
The FASEB Journal, 1996Structurally and functionally altered retinoic acid receptors have been associated with rare human neoplasms: acute promyelocytic leukemia and hepatocellular carcinoma. Whereas the retinoic acid receptor beta (RARbeta) rearrangement in hepatocellular carcinoma is unique, in acute promyelocytic leukemia (APL), RARalpha fusion to the promyelocytic ...

Retinoic Acid Receptor Alpha Amplifications and Retinoic Acid Sensitivity in Breast Cancers
Clinical Breast Cancer, 2013Molecular segmentation of breast cancer allows identification of small groups of patients who present high sensitivity to targeted agents. A patient, with chemo- and trastuzumab-resistant HER2-overexpressing breast cancer, who presented concomitant acute promyelocytic leukemia, showed a response in her breast lesions to retinoic acid, arsenic, and ...

Retinoids of a structurally new type, 4-(5,6,7,8-tetrahydro-5,5,8,8-tetramethyl-2-naphthalenylcarbamoyl)benzoic acid (Am80) and (E)-4-[3-(3,5-di-tert-butylphenyl)-3-oxo-1-propenyl]-benzoic acid (Ch55), were used for the investigation of retinoid receptors in some human cell lines.

Mechanisms of transactivation by retinoic acid receptors
BioEssays, 1993AbstractRetinoids play an important role in development and differentiation(1,2). Their effect is mediated through nuclear receptors, RAR (α, β and γ) and RXR (α, β and γ),Abbreviations. RAR: retinoic acid receptor; RXR: retinoid X receptor; T3:thyroid hormone receptor; VD3R: vitamin D3 receptor; PPAR: peroxisome proliferator activated receptor; EcR ...
