Effect of activation of liver X receptor alpha on cardiac & hepatic ABCC10 and SLC17A5 drug transporters in hypercholesterolemic rat model

Autor: Nahla E. El-Ashmawy, Naglaa F. Khedr, Mohamed Sallam, Ahmed Ibrahim Nossier

Publikováno v: Biochemical and Biophysical Research Communications. 610:133-139

Liver x receptor α (LXRα) is a ligand-activated transcription factor belonging to the nuclear receptor superfamily. Oxysterols (endogenous oxidized cholesterol derivatives) are the most potent endogenous LXRα-agonist. LXRα has a direct impact on

Autor: Naglaa M. Elsayed, Sanaa Eissa, Doaa Fayez Saeed, Manal F. Ismail, Ahmed Ibrahim Nossier, Nagwa Ibrahim Shehata, Suzy Mahmoud Morsy

Publikováno v: Analytical biochemistry. 609

Diabetic nephropathy (DN) is a major leading cause of kidney failure. So, early detection of DN by assessing urinary microRNAs (miRNAs) expression may be of clinical value. In this study, the diagnostic value of two urinary miRNAs (miR-210 & miR-34a)

Dual approach for the colorimetric determination of unamplified microRNAs by using citrate capped gold nanoparticles

Autor: Marwa Matboli, Ahmed Ibrahim Nossier, Hana Mahmoud Abdelzaher, Sanaa Eissa

Publikováno v: Mikrochimica acta. 185(4)

The authors describe a method for the colorimetric determination of unamplified microRNA. It is based on the use of citrate-capped gold nanoparticles (AuNPs) and, alternatively, a microRNA-probe hybrid or a magnetically extracted microRNA that serve

Direct detection of hyaluronidase in urine using cationic gold nanoparticles: A potential diagnostic test for bladder cancer

Autor: Ahmed Ibrahim Nossier, Sanaa Eissa, Hassan M.E. Azzazy, Manal F. Ismail, Mohamed A. Hamdy

Publikováno v: Biosensors and Bioelectronics. 54:7-14

Hyaluronidase (HAase) was reported as a urinary marker of bladder cancer. In this study, a simple colorimetric gold nanoparticle (AuNP) assay was developed for rapid and sensitive detection of urinary HAase activity. Charge interaction between polyan

Publikováno v: Cancer Epidemiology, Biomarkers & Prevention. 20:1657-1664

Background: Bladder cancer cells illustrate major disruptions in their DNA methylation patterns as compared with normal ones. Authors aimed to identify epigenetic molecular markers in urine for early detection of bladder cancer. Materials and Methods
