Summary
This summary is machine-generated.Urine-derived renal progenitor cells (UdRPCs) from chronic kidney disease (CKD) patients exhibit senescence, hindering kidney repair. The long non-coding RNA LINC01806 exacerbates this damage, presenting a potential therapeutic target for CKD.
Area Of Science
- Cell Biology
- Renal Medicine
- Molecular Biology
Background
- Urine-derived renal progenitor cells (UdRPCs) show potential for kidney repair.
- UdRPC functionality in chronic kidney disease (CKD) patients is not well understood.
- Senescence in UdRPCs could impede therapeutic applications.
Purpose Of The Study
- Investigate UdRPC functionality in CKD patients.
- Identify molecular mechanisms underlying UdRPC senescence in CKD.
- Explore LINC01806 as a potential therapeutic target for CKD.
Main Methods
- Isolation and characterization of UdRPCs from healthy and CKD individuals.
- Assessment of senescence markers (proliferation, KIM-1, SASP).
- Transcriptomics analysis to identify regulatory RNAs.
- Molecular assays to elucidate LINC01806 function and regulatory pathways (MAPK, IRF8-RUNX1).
Main Results
- CKD patients' UdRPCs displayed increased senescence, correlating with CKD severity.
- Senescence involved decreased proliferation, elevated KIM-1, and enhanced SASP.
- LINC01806 expression correlated with UdRPC damage and senescence.
- LINC01806 modulated KIM-1 and senescence factors via the MAPK pathway.
- IRF8-RUNX1 complex regulates LINC01806 expression.
Conclusions
- UdRPC senescence is a key factor in CKD progression.
- LINC01806 plays a critical role in inducing UdRPC damage and senescence.
- Targeting LINC01806 offers a novel therapeutic strategy for CKD.

Tumor suppressor genes are normal genes that can slow down cell division, repair DNA mistakes, or program the cells for apoptosis in case of irreparable damage. Hence, they play an essential role in preventing the proliferation of damaged cells.
The first-ever tumor suppressor gene called Rb was identified in retinoblastoma - a rare eye tumor in children. In inherited forms of the disease, a child inherits one defective copy of the Rb gene, which predisposes them to retinoblastoma. However,...
Rapidly dividing tumors, embryos, and wounded tissues require more oxygen than usual, lowering the oxygen concentration in the blood. At low oxygen or hypoxic conditions, an oxygen-sensitive transcription factor called the hypoxia-inducible factor 1 or HIF1 is activated. HIF1 is a dimeric protein of alpha (ɑ) and beta (β) subunits. Under optimal oxygen conditions, HIF1β is present in the nucleus while HIF1ɑ remains in the cytosol. HIF1ɑ is hydroxylated by prolyl...
Replicative cell senescence is a property of cells that allows them to divide a finite number of times throughout the organism's lifespan while preventing excessive proliferation. Replicative senescence is associated with the gradual loss of the telomere — short, repetitive DNA sequences found at the end of the chromosomes. Telomeres are bound by a group of proteins to form a protective cap on the ends of chromosomes. Embryonic stem cells express telomerase — an enzyme that adds...
Inositol-requiring kinase one or IRE1 is the most conserved eukaryotic unfolded protein response (UPR) receptor. It is a type I transmembrane protein kinase receptor with a distinctive site-specific RNase activity. As the binding mechanics of the misfolded proteins with the N-terminal domain of IRE-1 are unclear, three binding models — direct, indirect, and allosteric -- are proposed for receptor activation. Nevertheless, it is known that once a misfolded protein associates with IRE1, it...
Erythropoietin-producing hepatocellular carcinoma receptor (Eph) and its ligand, Eph receptor-interacting protein (Ephrin) were first discovered in the human carcinoma cell line, hence the name. Ephrin-Eph interaction guides cells to reach their appropriate location in adult tissues. They also play an essential role in the immune system by helping in immune cell migration, adhesion, and activation. Based on their structure and function, Eph is divided into two classes — EphA and EphB.
The glomerulus and Bowman's capsule are two essential components of the nephron, which is the functional unit of the kidney. These microscopic structures play a critical role in the process of blood filtration to produce urine.
Glomerulus: Structure and Function
The glomerulus is a tiny, intricate network of capillaries located at the beginning of the nephron. It's enveloped by the Bowman's capsule and receives its blood supply from an afferent arteriole, which divides into numerous...
