Summary: This study found that 4-GDB can alleviate colonic injury, reduce inflammation, and improve colonic barrier function by regulating cAMP/PKA/CREB and NF-kappa B pathways. This suggests that 4-GDB may be a potential agent for treating ulcerative colitis.

Summary: Class IIa histone deacetylases (HDAC) play a role in inflammation by promoting IKK activation and subsequent NF-kappa B activation. In this study, HDAC7 was found to be elevated in astrocytes after LPS challenge, leading to NF-kappa B activation, pro-inflammatory gene upregulation, and anxiety-like behaviors. Inhibition of HDAC7 attenuated LPS-induced inflammation and anxiety-like behaviors.

Summary: Hypoxia in cancer cells is caused by persistent inflammation and involves the activation of NF-kappa B and HIF-1 alpha. NF-kappa B promotes tumor development and maintenance, while HIF-1 alpha aids cellular proliferation and adaptability to angiogenic signals. The key oxygen-dependent regulator of HIF-1 alpha and NF-kappa B activity is hypothesized to be Prolyl hydroxylase-2 (PHD-2). In non-hypoxic tumor cells, PHD-2 is inactive due to pyruvate-mediated competitive inhibition of 2-oxo-glutarate, leading to the canonical activation of NF-kappa B.

Summary: The novel polycation PAG induced apoptosis in GBM cells, while the commonly used polycation PAH induced necrosis. PAG coating limited the proliferation of GBM8901 cells and induced apoptotic cell death via the NF-kappa B pathway by the regulation of TGF-beta. These findings suggest that PAG has potential in suppressing cancer cell proliferation and promoting neural viability.

Summary: This study identified two miRNAs, miR-210 and miR-3570, which negatively regulate host antibacterial immunity in miiuy croaker. These miRNAs inhibit inflammatory cytokine production by targeting RIPK2, thereby modulating the NF-kappa B signaling pathway and playing a regulatory role in bacteria-induced inflammatory response.

Summary: Microglial cells have an important role in the brain's immune system. LOX-1 expression was confirmed in microglial cells in the neonatal hypoxic-ischemic encephalopathy model brain. LOX-1 activates cytokines and chemokines through intracellular pathways. This study investigated the role and molecular mechanism of LOX-1 gene transcription in microglial cells under hypoxic and ischemic conditions.

Summary: Hypoxia has broad effects on cardiomyocyte function and viability, and this study reveals that the transcriptional coactivator PGC-1 alpha is down-regulated in hypoxia through the nuclear localization of NF-kappa B p65 subunit and its association with the PGC-1 alpha promoter.

Summary: The NF-kappa B signaling pathway plays a critical role in various biological processes and can be activated during exercise. This study demonstrates that exercising to exhaustion activates NF-kappa B signaling in human skeletal muscle, and the regulation of this pathway is influenced by metabolite accumulation and oxygen levels. These findings have important implications for the interpretation of previous studies and the design of future experiments.
