Temporal regulation of Cat-1 (cationic amino acid transporter-1) gene transcription during endoplasmic reticulum stress.
Expression of the Cat-1 gene (cationic amino acid transporter-1) is induced in proliferating cells and in response to a variety of stress conditions. The expression of the gene is mediated via a TATA-less promoter. In the present study we show that an Sp1 (specificity protein 1)-binding site within a GC-rich region of the Cat-1 gene controls its basal expression and is important for induction o...
متن کاملArginine uptake is attenuated through modulation of cationic amino-acid transporter-1, in uremic rats.
Endothelial cell dysfunction (ECD) is a common feature of chronic renal failure (CRF). Defective nitric oxide (NO) generation due to decreased endothelial NO synthase (eNOS) activity is a crucial parameter characterizing ECD. L-arginine is the sole precursor for NO biosynthesis. Among several transporters that mediate L-arginine uptake, cationic amino-acid transporter-1 (CAT-1) acts as the spec...
متن کاملEvaluation of Cardiac Dysfunction in Children and Adolescents with Type 1 Diabetes Mellitus
Background This study was conducted to identify cardiac dysfunction and the relationship of hemoglobin A1c (HbA1c) levels and serum lipids to echocardiographic indices in children and adolescents with T1DM. Materials and Methods: This case-control study was conducted on 100 cases including 50 children and adoles...
متن کاملEstradiol augments while progesterone inhibits arginine transport in human endothelial cells through modulation of cationic amino acid transporter-1.
Decreased generation of nitric oxide (NO) by endothelial NO synthase (eNOS) characterizes endothelial dysfunction (ECD). Delivery of arginine to eNOS by cationic amino acid transporter-1 (CAT-1) was shown to modulate eNOS activity. We found in female rats, but not in males, that CAT-1 activity is preserved with age and in chronic renal failure, two experimental models of ECD. In contrast, durin...
متن کاملThe cationic amino acid transporter 2 is induced in inflammatory lung models and regulates lung fibrosis
BACKGROUND Arginine is an amino acid that serves as a substrate for the enzymes nitric oxide synthase (NOS) and arginase, leading to synthesis of NO and ornithine, respectively. As such, arginine has the potential to influence diverse fundamental processes in the lung. METHODS We used mice deficient in cationic amino acid transporter (CAT) 2 in models of allergic airway inflammation and pulmo...
