| Description: | NEAT1 was overexpressed and miR-22-3p was underexpressed in sepsis patients and lipopolysaccharide (LPS)-induced AKI cell models. In summary, our data showed that NEAT1 promoted LPS-induced HK2 cell injury via regulating the miR-22-3p/CXCL12/NF-κB signaling pathway, suggesting that NEAT1 knockdown might be a potential pathway for alleviating sepsis-induced AKI. |
| Causality: | Yes |
| Causal Description: | Knockdown of NEAT1 could promote viability and suppress apoptosis and the inflammatory response in LPS-induced HK2 cells. |

| Disease Name: | Acute Kidney Injury |
| Sample: | TECs |
| Dysfunction Pattern: | Interaction(miR-129-5p) |
| Validated Method: | In Vivo Experiment//Northern Blot//Western Blot//ISH//qPCR//Tunel//RIP//Luciferase Report Assay//RNA-seq//Cell Apoptosis Assay//IHC//ChIP |
| Description: | By high-throughput RNA sequencing, we found that Neat1_2, a transcript variant of Neat1, was upregulated in 40-min ischemia/reperfusion injury (IRI), which resulted in the development of renal fibrotic lesions. The upregulation of Neat1_2 in hypoxia-treated TECs was attributed to p53 transcriptional regulation.Mechanistically, Neat1_2 shares miRNA response elements with FADD, CASP-8, and CASP-3. Neat1_2 competitively binds to miR-129-5p and prevents miR-129-5p from decreasing the levels of FADD, CASP-8, and CASP-3, and ultimately facilitates TEC apoptosis. Increased expression of Neat1_2 associated with kidney injury and TEC apoptosis was recapitulated in human AKI, highlighting its clinical relevance. |
| Causality: | Yes |
| Causal Description: | Gain- and loss-of-function studies, both in vitro and in vivo, demonstrated that Neat1_2 promoted apoptosis of injured TECs induced by IRI and caused tubulointerstitial inflammation and fibrosis. |
