Tacrolimus is currently the cornerstone of immunosuppressive protocols for renal transplant recipients. Despite therapeutic whole blood monitoring, tacrolimus is associated with nephrotoxicity and it has been hypothesized that intrarenal accumulation of tacrolimus and/or its metabolites are involved. As tacrolimus is a substrate of P-glycoprotein (P-gp), the expression and activity of this efflux transporter could influence the levels of tacrolimus in renal tissue. The primary aim of this study was to develop and validate a method for quantification of tacrolimus in tissue homogenates from single human renal core biopsies. The secondary aim was to provide measures of P-gp expression and of the demethylated metabolites of tacrolimus in the same renal biopsy.

Apixaban is metabolized by cytochrome P450 (CYP) 3A4 in the liver and intestine, undergoes direct intestinal excretion, and is a substrate to permeability glycoprotein (P-gp) and breast cancer resista...
Increased tacrolimus blood concentration by Beni-Madonna - a new hybrid citrus cultivar categorized as 'Tangor', in a liver transplant patient: likely furanocoumarin-mediated inhibition of CYP3A4 or P-glycoprotein.
A drug interaction leading to greater exposure to tacrolimus.
While tacrolimus and everolimus have common metabolic pathways through CYP3A4/5, tacrolimus is metabolized solely by CYP3A4 in recipients with the/. The purpose of this study was to evaluate how the a...
Values of mass concentration of tacrolimus in whole blood are commonly used by the clinicians for monitoring the status of a transplant patient and for checking whether the administered dose of tacrol...
Acetyl coenzyme A is involved in several key metabolic pathways. Its concentration can vary considerably in response to physiological or pathological conditions making it a potentially valuable biomar...
Protein Concentration in Human Embryo Culture Media remains assigned to the manufacturers with no clear evidence on which concentration is ideal.
The purpose of this study is to demonstrate that the biliary concentration of TCR is a good marker of its immunosuppressive activity.
The purpose of this study is to evaluate two groups of kidney transplant recipients, to determine the proportion of patients that achieve therapeutic blood concentrations of tacrolimus by ...
Renal transplantation is the treatment of choice of the chronic renal insufficiency arrived at its final stage. Tacrolimus is an immunosuppressant treatment used for the prevention of epis...
Therapeutic drug monitoring (TDM) of immunosuppressive drugs is used to improve the immunosuppressive effect while minimizing the toxicity related to exposition to high serum levels. Altho...
A 12-KDa tacrolimus binding protein that is found associated with and may modulate the function of calcium release channels. It is a peptidyl-prolyl cis/trans isomerase which is inhibited by both tacrolimus (commonly called FK506) and SIROLIMUS.
A serine threonine kinase that controls a wide range of growth-related cellular processes. The protein is referred to as the target of RAPAMYCIN due to the discovery that TACROLIMUS (commonly known as rapamycin) forms an inhibitory complex with TACROLIMUS BINDING PROTEIN 1A that blocks the action of its enzymatic activity.
A family of immunophilin proteins that bind to the immunosuppressive drugs TACROLIMUS (also known as FK506) and SIROLIMUS. EC 5.2.1.-
Platelet membrane glycoprotein IIb is an integrin alpha subunit that heterodimerizes with INTEGRIN BETA3 to form PLATELET GLYCOPROTEIN GPIIB-IIIA COMPLEX. It is synthesized as a single polypeptide chain which is then postranslationally cleaved and processed into two disulfide-linked subunits of approximately 18 and 110 kDa in size.
A widely expressed transmembrane glycoprotein that functions as a METASTASIS suppressor protein. It is under-expressed in a variety of human NEOPLASMS.
Nephrology - kidney function
Nephrology is a specialty of medicine and pediatrics that concerns itself with the study of normal kidney function, kidney problems, the treatment of kidney problems and renal replacement therapy (dialysis and kidney transplantation). Systemic conditions...
