Background: Sepsis-associated encephalopathy (SAE) is a complication of the central nervous system in patients with sepsis. Currently, no effective treatment for sepsis is available. Hydrogen plays a protective role in different diseases; however, the detailed mechanism of hydrogen-treated disease remains unclear.

Background: Chromosomal heterogeneity leads to the abnormal expression and mutation of tumor-specific genes. Drugs targeting oncogenes have been extensively developed. However, given the random mutation of tumor suppressor genes, the development of its targeted drugs is difficult.

Sepsis is a disease characterized by multiple organ failure caused by immune hyperactivation and cytokine storms. Studies have shown that the incidence of sepsis in melanoma patients is substantially lower compared to the general population. It is also observed that experimental tumor-bearing animals have high survival rates after sepsis induction, suggesting that tumors may suppress sepsis-associated immune overactivation, thereby alleviating sepsis.

Circular RNAs (circRNAs), a novel class of endogenous long non-coding RNAs, have attracted considerable attention due to their closed continuous loop structure and potential clinical value. In this study, we investigated the function of circFASTKD1 in vascular endothelial cells. CircFASTKD1 bound directly to miR-106a and relieved its inhibition of Large Tumor Suppressor Kinases 1 and 2, thereby suppressing the Yes-Associated Protein signaling pathway.

Pathological vascular endothelial damage caused by hypoxia is the basis of many vascular-related diseases. However, the role of circular RNA in hypoxic vascular injury is still poorly understood. Here, we found that hypoxia induced AFF1 circular RNA (circAFF1) can activate the SAV1/YAP1 and lead to the dysfunction of vascular endothelial cells.
