Project description:In this study, we report the protective effect of LINE1 intervention on vascular calcification. To elucidate the molecular mechanisms underlying the protective role of LINE1 inhibition, we employed RNA sequencing to identify gene expression changes under LINE1 suppression conditions. Our findings provide insights into the pathways involved in modulating vascular calcification and highlight LINE1 as a potential therapeutic target.
Project description:Vascular calcification is the abnormal deposition of calcium phosphates within the blood vessels. Although it significantly contributes to the development of cardiovascular disease, much remains unknown about the mechanisms driving this process. Recent advances have shown that microRNAs (miRNAs) could be critical in regulating the biological processes driving vascular calcification. Here, we investigated whether miR-26b could regulate vascular calcification. By performing bulk RNA-seq of the aorta of miR-26bKO mice, we identified cell-specific targets and demonstrated that BMP signalling is dysregulated in aortic cells.

Recent advances have shown that microRNAs (miRNAs) could be critical in regulating the biological processes driving vascular calcification. Here, we investigated whether miRNA-26b (miR-26b) could regulate vascular calcification. By performing scRNA-seq of the aorta of miR-26b knockout (miR-26bKO) mice, we identified cell-specific targets and demonstrated that components of the BMP signalling pathway are dysregulated in the aortic cell types.
Project description:In this study,we report the protective effect of BCKDHA on vascular calcification in chronic kidney disease (CKD). To explore the underlying mechanism of BCKDHA's protective effect on vascular calcification, we performed high-throughput RNA sequencing to identify the target genes of BCKDHA.
Project description:In this study, we report the protective effect of β-hydroxybutyrate (BHB) on vascular calcification in chronic kidney disease (CKD). To further investigate the mechanism underpinning the protective effect of BHB on vascular calcification, we performed high-throughput RNA-seq to identify the target gene of BHB. Our data demonstrate that BHB supplementation inhibits vascular calcification in CKD via targeting HDAC9.
Project description:Objective: To investigate the treatment and mechanism of lanthanum hydroxide on hyperphosphate-induced vascular calcification in chronic renal failure. Methods: Develop a rat model of CKD hyperphosphatemia. Rats were randomly allocated to the model, lanthanum hydroxide, lanthanum carbonate, Calcium carbonate groups. Determination of serum biochemical indicators and the determination of pathological analysis of kidney tissue, Von Kossa staining and CT scan on the aortic vessels. The proteomic analysis of aortic tissue in Vivo. A calcified VSMCs model was established. The calcium content and ALP activity were measured. RT-PCR measures the mRNA expression level of SM22α, Runx2, BMP-2 and TRAF6. Western Blot measures the protein expression level of SM22α, Runx2, BMP-2, TRAF6 and NF-κB. Results: Through the detection of serum biochemical indicators and pathological analysis of kidney tissue, it can be summaryed that lanthanum hydroxide has the effect of delaying the progression of renal failure and protecting renal function. We found that the administration of lanthanum hydroxide delayed the development of vascular calcification induced by hyperphosphatemia in CKD. It can be concluded that lanthanum hydroxide may affect vascular calcification through the NF-κB pathway. , To deal with Lanthanum chloride (LaCl3) inhibited phosphate induced calcification, osteo-/chondrogenic transdifferentiation, and NF-κB signaling in cultured VSMCs. Lanthanum hydroxide significantly reduces the expression of Runx2, BMP-2, TRAF6 and NF-κB. Conclusion: Lanthanum hydroxide has a protective effect on the kidneys, and can delay the development of vascular calcification by reducing serum phosphorus concentration.
Project description:In this study, we repoort the protective effect of ursolic acid (UA) on vascular calcification in chronic kidney disease. To elucidate the molecular mechanism underlying the anti-vascular calcification effect of UA, we performed RNA-seq to identify the gene expresion under UA treatmment.
