Sepsis is a life-threatening disease due to a dysregulated host response to infection, with an unknown regulatory mechanism for prognostic necroptosis-related genes (NRGs). Using GEO datasets GSE65682 and GSE134347, we identified six NRG biomarkers ( ATRX , TSC1 , CD40 , BACH2 , BCL2 , and LEF1 ) with survival and diagnostic significance through Kaplan-Meier (KM) and receiver operating characteristic (ROC) analyses. Afterward, the ingenuity pathway analysis (IPA) highlighted enrichment in hepatic fibrosis pathways and BEX2 protein. ⋯ Additionally, DrugBank analysis identified paclitaxel, docetaxel, and rasagiline as potential BCL2-targeting sepsis treatments. Finally, real-time quantitative PCR confirmed ATRX, TSC1, and LEF1 downregulation in sepsis samples, contrasting CD40's increased expression in CTL samples. In conclusion, ATRX , TSC1 , CD40 , BACH2 , BCL2 , and LEF1 may be critical regulatory targets of necroptosis in sepsis, providing a basis for further necroptosis-related studies in sepsis.

Background: Sepsis-induced acute kidney injury (SI-AKI) is a kind of kidney dysfunction, which brings a lot of suffering. This study aimed to figure out the role of the miR-218-5p/PGC-1α axis in SI-AKI. Methods: AKI mouse model was established through cecal ligation and puncture. ⋯ Inhibition of PGC-1α annulled the role of miR-218-5p silencing in cells. In vivo , miR-218-5p overexpression partly reversed the protective role of ZLN005 in SI-AKI mice. Conclusion: miR-218-5p targeted PGC-1α to disrupt mitochondrial biogenesis, thereby exacerbating SI-AKI.
