Pharmacologic therapeutics in sarcopenia with chronic kidney disease
Ran-hui Cha
Received April 23, 2023  Accepted October 24, 2023  
Inflammation, metabolic acidosis, renin-angiotensin system activation, insulin resistance, and impaired perfusion to skeletal muscles, among others, are possible causes of uremic sarcopenia. These conditions induce the activation of the nuclear factor-kappa B and mitogen-activated protein kinase pathways, adenosine triphosphate ubiquitin-proteasome system, and reactive oxygen species system, resulting in protein catabolism. Strategies for the prevention and treatment of sarcopenia in chronic...

Min Jung Kong, Sang Jun Han, Sung Young Seu, Ki-Hwan Han, Joshua H. Lipschutz, Kwon Moo Park
Received April 7, 2023  Accepted July 27, 2023  
Background: The primary cilium protrudes from the cell surface and functions as a mechanosensor. Recently, we found that water intake restriction shortens the primary cilia of renal tubular cells, and a blockage of the shortening disturbs the ability of the kidneys to concentrate urine. Here, we investigate whether high water intake (HWI) alters primary cilia length, and if so, what...
