The NKCC2A is a splice variant of the Na+K+2Cl- co-transporter 2 (Slc12a1), which is abundantly expressed in macula densa and in the apical membrane of the tubular cells in the kidney. Most of our knowledge regarding NKCC2 function is limited to the kidney, the organ where NKCC2 is abundantly expressed. However, recent studies have demonstrated that NKCC2 is also expressed in extra-renal tissues. This study was designed to determine if NKCC2A, a splice variant of NKCC2 has an impact on behavior and nervous system activity of mice. To these ends, we used mice (wild type, WT), lacking a single or …
Role Of Angiotensin Ii Type 1a Receptors On Renal And Urinary Angiotensin Converting Enzyme 2 (Ace2) And Neprilysin (Nep) In The Two-Kidney One-Clip (2k1c) Model Of Renovascular Hypertension, Laale F. Alawi

Activation of the renin angiotensin system (RAS) and increased formation of angiotensin (Ang) II contribute to the progression of chronic kidney disease (CKD). Ang II, the major biologically active peptide of RAS, acts mainly as a vasoconstrictor through binding to the Ang II type 1 receptor (AT1R), which leads to increased blood pressure, fluid retention, and aldosterone secretion. The actions of Ang II are antagonized by its conversion to the vasodilator Ang (1-7), partly generated by the action of angiotensin converting enzyme 2 (ACE2) and/or neprilysin (NEP). The metalloprotease ADAM17 has a crucial role in the shedding of renal ACE2 …

The Present study was designed to examine the role of agglomeration, density and the resulting fractal dimension of nanomaterials in cell culture media. Studies were completed on the kinetics and the process of agglomeration, as well as how to calculate fractal dimensions. The correlation of such complex agglomeration patterns of nanomaterials in culture media, their translocation into cells, and toxic effects were observed. Our results showed that smaller primary particles agglomerated at an accelerated rate when compared to the larger primary particles. They also demonstrated increased cellular uptake, but exhibited lower fractal dimensions. The larger primary particle agglomerates displayed obvious …
