1. Retinoids and vitamin D in skin and parathyroid glands
Sammanfattning : Vitamin D3 (VitD3) and retinoids are important factors involved in differentiation and proliferation in many cell systems. Their effects in skin, where retinoids and vitamin D are known to be crucially involved in keratinocyte differentiation and function,, and in the parathyroid, the overall regulatory organ in calcium homeostasis were studied.

2. On retinoid receptors, Nurr1 and related transcription factors in the CNS
Sammanfattning : It has long been known that retinoids (vitamin A derivatives) are required for normal development and growth; in excess however metabolites such as all-trans retinoic acid are potent teratogens. Retinoids exert their effects through transcription factors known as the retinoic acid receptors (RARam -ß and -y) and retinoid X receptors (RXRa, -ß and -y). LÄS MER
3. Disruption of vitamin A metabolism by dioxin
Sammanfattning : Vitamin A (retinoids) is a nutrient that plays a central role in development and remains essential for cell growth and differentiation throughout life. Dioxins are polychlorinated organic pollutants known to negatively affect the storage and body clearance of retinoids. LÄS MER
4. Constitutive and TCDD-induced expression of Ah receptor responsive genes with special focus on the brain and pituitary
Sammanfattning : The 2,3,7,8-tetrachlorodibenzo-p-dioxin (2,3,7,8-TCDD) and related substances are ubiquitous environmental pollutants causing a number of pathological alterations, the most severe being progressive anorexia and body weight loss. The effects on body weight homeostasis suggest a possible involvement of the nervous system and neuroendocrine areas including the pituitary gland. LÄS MER
5. 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) disrupts vitamin A homeostasis in rodents : quantitative and mechanistic studies to support risk assessment
Sammanfattning : 2,3,7,8-Tetrachlorodibenzo-p-dioxin (TCDD) exposure is well-known to disrupt Vitamin A (retinoid) homeostasis in rats, resulting in decreased hepatic storage, as well as increased metabolism and excretion of retinoids. The aims of this thesis were (1) to clarify the species and strain sensitivity of TCDDinduced retinoid disruption and (2) to identify cellular targets of TCDD-induced retinoid disruption. LÄS MER
