Potential Role of the Resident Mesenchymal Stem-Like Cells in Renal Fibrogenesis after Ureteral Obstruction

Stem Cells International, 2019
The mechanisms of renal fibrogenesis after ureteral obstruction remain unclear. We tried to primarily expand mesenchymal stem cells from renal tissues and then investigated their role in fibrogenesis after ureteral obstruction.

Scintigraphy and Doppler ultrasonography for the evaluation of obstructive urinary calculi [PDF]

, 2001
Forty-seven patients with unilateral obstructive calculi (12 males and 35 females) were submitted to 99mTc-diethylene triamine pentaacetic acid (DTPA) or 99mTc-dimercaptosuccinic acid (DMSA) scans for assessment of renal function.

D‐glucuronyl C5‐Epimerase Binds to EGFR to Suppress Kidney Fibrosis

Advanced Science, EarlyView.
Glucuronyl C5‐epimerase (Hsepi, gene name Glce) is a key enzyme catalyzing heparan sulfate (HS) chain biosynthesis in HS proteoglycans, which are ubiquitously expressed on cell membranes. In normal renal tubular cells, Glce binds to the intracellular domains of EGFR, maintaining stable and orderly EGFR phosphorylation.

Recent Advances in Ureteral Stents

대한영상의학회지, 2019
A ureteral stent is widely used to drain ureteral obstructions, which allows urine to bypass the obstruction. The double J stent, a representative ureteral stent, has undergone many advancements in material and design recently.

Robot-assisted excision of partially obstructing ureteral fibroepithelial polyp in a child: A case report and review of the literature

Journal of Pediatric Surgery Case Reports, 2022
Background: Fibroepithelial polyps are benign tumors located in the upper ureter and ureteropelvic junction. Given their location in rare cases they can cause hydronephrosis.

Restoration of SIRT3 Expression in Aged Mice Alleviates UUO‐Induced Renal Fibrosis by Reducing GSK‐3β Hyperacetylation

Advanced Science, EarlyView.
SIRT3 expression is significantly downregulated in the aged kidney, rendering the kidney more vulnerable to fibrotic changes in obstructive nephropathy. By promoting GSK‐3β deacetylation, SIRT3 indirectly inhibits Wnt/β‐catenin signaling, thereby suppressing renal fibrosis.

Single Cell and Spatial Transcriptomics Define a Proinflammatory and Profibrotic Niche After Kidney Injury

Advanced Science, EarlyView.
By integrating single‐cell RNA sequencing and spatial transcriptomics, tenascin C (TNC) is unveiled as a central organizer of the proinflammatory and profibrotic niche in kidney fibrosis. TNC promotes macrophage activation through TLR4/NF‐κB signaling, leading to renal inflammation and fibrosis.
