ZnT8 Exerts Anti-apoptosis of Kidney Tubular Epithelial Cell in Diabetic Kidney Disease Through TNFAIP3-NF- κB Signal Pathways
Biol Trace Elem Res. 2022 Jul 23. doi: 10.1007/s12011-022-03361-w. Online ahead of print.ABSTRACTApoptosis of kidney tubular epithelial cells contributes to diabetic kidney disease (DKD) pathophysiology, but the mechanisms are not fully understood. Zinc transporter protein member 8 (ZnT8, SLC30A8) is a susceptive gene in diabetes. Here, we aim to investigate whether ZnT8 has effects on pathophysiology of DKD. The animal groups include control, ZnT8KO mice, STZ-induced, and ZnT8-KO-STZ. STZ-induced DKD was performed in male C57BL/6 J mice and in ZnT8-KO mice. High glucose (HG)-induced apoptosis in a normal rat kidney tubula...

TonEBP Suppresses the HO-1 Gene by Blocking Recruitment of Nrf2 to Its Promoter
Discussion Dynamic changes in the functional phenotype of macrophages are associated with pathogenesis of inflammatory diseases (5–7). TonEBP primes macrophages toward an M1 phenotype, which has pro-inflammatory properties. TonEBP does this by promoting expression of pro-inflammatory genes via interaction with NF-κB (36) and by binding directly to the promoter (37, 64). In addition, TonEBP suppresses expression of the anti-inflammatory cytokine IL-10 by limiting chromatin access to the promoter (37). The pro-inflammatory function of TonEBP suggests that inhibiting its expression or activation could suppres...

NF κB and Kidney Injury
Conclusion As a critical regulator of inflammation and cell survival, the NFκB pathway is a promising target for diagnosing and treating kidney diseases. For modulation of the NFκB pathway in the clinic, a number of molecules can effectively inhibit NFκB signaling by targeting the receptors, associated adaptors, IKKs, IκBs and transcriptional regulators (144). There is further clinical evidence on small-molecule inhibitors of IKKα and NIK from recent trials on anti-cancer therapies (145). These clinical trials showed that the cancer-selective pharmacodynamic response of DTP3, the co...

HDAC11 deletion reduces fructose-induced cardiac dyslipidemia, apoptosis and inflammation by attenuating oxidative stress injury.
Abstract Diabetes mellitus (DM) is a risk factor for abnormal heart development, but the molecular mechanism remains obscure. Histone deacetylase 11 (HDAC11), the most recently identified histone deacetylase, is the sole member of class IV HDACs. However, its role in diabetic cardiac injury is still poorly understood. In the present study, we attempted to explore the effects of HDAC11 on fructose (Fru)-induced cardiac injury using the wild type (HDAC11+/+) and knockout (HDAC11-/-) mice. The results indicated that HDAC11 was significantly expressed in human and mouse diabetic heart failure (DHF) hearts. HDAC11-/- r...
