1. A new polysaccharide isolated from Dendrobium offcinale, stimulates aquaporin-3 expression in human keratinocytes
Abstract Polysaccharides are the major components of the water extract from Dendrobium officinale, which have been thoroughly studied and found to have favorable moisturizing properties on mammalian skin. However, the structures of polysaccharides on skin moisturizing properties remains unknown. The aim of this study was to extract and characterize D. offici

2. Renal Dose Dopamine Mediates the Level of Aquaporin-2 Water Channel (Aqp2) in Broiler Chickens
ABSTRACT Aquaporin 2 (AQP2) is a small protein located in the collecting tubules of kidneys; it plays an important role in the concentration and production of urine. The aim of this study was to determine the expression level of the AQP2 gene in the kidney of broiler chickens after the administration of renaldose dopamine. Broiler chickens (25 days-old) were

3. Aquaporins and the control of the water status in coffee plants
Six aquaporin (AQP) homologues were identified in three coffee species (Coffea arabica, C. Canephora, and C. racemosa), including four plasma membrane intrinsic proteins (PIP1;1, PIP1;2, PIP2;1, and PIP2;2) and two tonoplast intrinsic proteins (TIP1;1 and TIP1;2). In order to better understand the role of these genes in coffee, C. arabica cvs Catuaí and Mun

4. Vias intracelulares da ação do Sildenafil no diabetes insipidus induzido pelo lítio / Sildenafil action in lithium-induced NDI: intracellular pathway
Patients taking lithium to treat bipolar disorder often present polyuria and urinary concentrating defect. In addition, lithium-treated animals present lower cyclic adenosine monophosphate production in response to vasopressin. Sildenafil (Sil), a phosphodiesterase 5 (PDE5) inhibitor, elevates intracellular cyclic guanosine monophosphate (cGMP) levels, leadi

6. RizobactÃrias para o tratamento de sementes: seleÃÃo, eficiÃncia em campo e modos moleculares de aÃÃo. / Rhizobacteria for cotton seed treatment: screening, field efficacy and molecular modes of action
Rhizobacteria may act on eradication of seed-associated pathogens and plant protection against biotic and abiotic stresses. The present work aimed to select rhizobacteria to control cotton diseases and assess the molecular modes of action involved. A total of 368 rhizobacteria were tested for the controlo f damping-off and bacterial blight by treating infect

8. Rosiglitazona, agonista do PPAR-y "Peroxisome Proliferator-Activated Receptor-y" reverte a nefrotoxicidade induzida pelo tenofovir-DF / The peroxisome proliferator-activated receptor-y agonist rosiglitazone reverses tenofovir-induced nephrotoxicity
Objective: To characterize the mechanisms of tenofovir disoproxil fumarate (TDF)- induced nephrotoxicity and the protective effects of rosiglitazone (RSG), a peroxisome proliferator-activated receptor-y agonist. Methods: Rats were treated for 30 days with one of two TDF doses (50 or 300 mg/kg of food), to which RSG (92 mg/kg of food) was added for the last 1

9. Role of renal aquaporins in escape from vasopressin-induced antidiuresis in rat.
The purpose of this study was to investigate whether escape from vasopressin-induced antidiuresis is associated with altered regulation of any of the known aquaporin water channels. After 4-d pretreatment with 1-deamino-[8-D-arginine]-vasopressin (dDAVP) by osmotic mini-pump, rats were divided into two groups: control (continued dDAVP) and water-loaded (cont

10. Rat renal arcade segment expresses vasopressin-regulated water channel and vasopressin V2 receptor.
The arcades are long, branched renal tubules which connect deep and mid-cortical nephrons to cortical collecting ducts in the renal cortex. Because they are inaccessible by standard physiological techniques, their functions are poorly understood. In this paper, we demonstrate that the arcades are a site of expression of two proteins, aquaporin-2 (the vasopre

11. Early Effects of Salinity on Water Transport in Arabidopsis Roots. Molecular and Cellular Features of Aquaporin Expression1
Aquaporins facilitate the uptake of soil water and mediate the regulation of root hydraulic conductivity (Lpr) in response to a large variety of environmental stresses. Here, we use Arabidopsis (Arabidopsis thaliana) plants to dissect the effects of salt on both Lpr and aquaporin expression and investigate possible molecular and cellular mechanisms of aquapo

12. Architecture and Selectivity in Aquaporins: 2.5 Å X-Ray Structure of Aquaporin Z
Aquaporins are a family of water and small molecule channels found in organisms ranging from bacteria to animals. One of these channels, the E. coli protein aquaporin Z (AqpZ), has been shown to selectively conduct only water at high rates. We have expressed, purified, crystallized, and solved the X-ray structure of AqpZ. The 2.5 Å resolution structure of A
