Summary: The NF-kappa B transcription factor family plays important roles in inflammation, immune response, and bone metabolism. Its activation occurs through different pathways and is crucial for osteoclast differentiation. Recent studies have identified genetic mutations in NF-kappa B signaling molecules associated with diseases like osteopetrosis.

Summary: Redox biology is a rapidly developing field in modern biological sciences, with a focus on the roles of redox homeostasis in health and disease. Various redox pairs in cells/tissues are responsible for maintaining/regulating redox balance, with Nrf2 identified as a key regulator. The interactions between vitagenes and NF-kappa B in relation to redox balance, immunity, and gut health in poultry production require further research to better understand their impact on stress-related disturbances.

Summary: Tangeretin, a natural flavonoid with anti-inflammatory properties, has been found to inhibit inflammation and extracellular matrix (ECM) degradation, effectively preventing the progression of osteoarthritis (OA). These effects are mediated through the Nrf2/NF-kappa B and MAPK/NF-kappa B pathways.

Summary: This study investigated the effect of celastrol on osteoarthritis (OA) and identified the mechanisms involved. The results showed that celastrol delayed cartilage damage, reduced osteophyte formation and bone resorption in an OA rat model. In vitro experiments also demonstrated that celastrol suppressed the production of inflammatory factors and inhibited matrix degradation. Furthermore, celastrol inhibited the TLR2/NF-kappa B signaling pathway. These findings suggest that celastrol could be a potential therapy for OA by targeting this signaling pathway.

Summary: The study investigated the effects of the GSK-3 beta/NF-kappa B pathway on CD47 expression after MI in rats. Results showed that GSK-3 beta upregulates CD47 expression by activating NF-kappa B, leading to myocardial cell damage and apoptosis. SB216763 and the NF-kappa B inhibitor SN50 were found to reduce CD47 expression and apoptosis in hypoxic conditions.

Summary: This study confirmed that cytoplasmic protein TRAF2 can be methylated by SMYD2 and contribute to the continuous activation of NF-kappa B signaling pathway. Knocking down SMYD2 showed varying degrees of mitigation in acute and chronic inflammation mouse models. Moreover, lysine-specific demethylase LSD1 was found to resist the methylation of TRAF2 induced by SMYD2.

Summary: Gene variants associated with longevity were found to be enriched in the nPKC and NF-kappa B signaling pathways, with non-coding variants modulating the expression of cognate genes to reduce signaling. This matches genetic studies in other model organisms and suggests evolutionary conservation of reduced PKC and NF-kappa B signaling in exceptional longevity, possibly including humans.

Summary: Venous thromboembolism is a common and costly health problem. Deep-vein thrombosis can cause severe consequences. Inflammatory response is considered an important pathway for triggering venous thromboembolism, and regulating it through the NF-kappa B signaling pathway may provide new solutions for prevention and treatment of thrombosis.

Summary: This study evaluated the role of ERK2 and NF-kappa B in TRAIL cytotoxicity during cisplatin treatment. The findings suggest that induced ERK2 activity enhances TRAIL susceptibility via DR5 expression, while basal ERK2 activity suppresses TRAIL-R expression. The ERK2/NF-kappa B signaling pathway has a dual role in TRAIL susceptibility by differentially regulating TRAIL-R expression in the same cellular system.

Summary: This study found that prostate cancer tumors with concomitant inhibition of PP2A and PTEN are particularly aggressive, with low patient survival rates. Overexpression of PME-1 inhibits anoikis in PTEN-deficient prostate cancer cells. The results suggest that PME-1 may be a candidate biomarker for particularly aggressive PTEN-deficient prostate cancer.

Summary: This study presents cryo-EM structures of membrane-coated CHMP2A-CHMP3 filaments from Homo sapiens, which reveal helical filaments assembled by CHMP2A-CHMP3 heterodimers in the open ESCRT-III conformation. Inter-filament interactions are electrostatic, facilitating filament sliding upon VPS4-mediated polymer remodeling. Fluorescence microscopy and high-speed atomic force microscopy imaging confirm that VPS4 can constrict and cleave CHMP2A-CHMP3 membrane tubes. It is concluded that CHMP2A-CHMP3-VPS4 act as a minimal membrane fission machinery.

Summary: Coxsackievirus and adenovirus receptor (CAR) is a crucial cell-cell adhesion receptor that plays a key role in maintaining epithelial barrier integrity and mediating immune cell transmigration across epithelial tissues. CAR is emerging as a potential mediator of tumorigenesis and a target for viral therapy delivery on cancer cells, but its function is tightly regulated and the contributions to disease progression are likely to be context specific.

Summary: In molecular simulations, periodic boundary conditions are commonly used to avoid surface effects. However, this can result in broken molecular assemblies which complicates data interpretation. To address this issue, we propose MDVWhole, an open-source algorithm capable of repairing broken assemblies caused by periodic boundary conditions. This method is efficient and suitable for processing both individual simulation frames and long trajectories with millions of points.

Summary: The shear viscosity of lipid membranes is crucial for determining the rates of diffusion-limited reactions and the movement of lipids, proteins, and other membrane constituents. This study uses molecular dynamics simulations to extract the shear viscosities of lipid membranes under various conditions. The results demonstrate the significant effects of protein concentration, cholesterol concentration, and temperature on membrane viscosity.

Summary: Dermatofibromas (DFs) are common, benign fibrous skin tumors that can occur at any skin site. In some cases, DFs are multiple and familial, but the mechanisms leading to these lesions are currently unclear. This study identified a variant in the RND3 gene that encodes the small GTPase RhoE, and loss of RhoE function was found to enhance collagen activation and integrin activation, resulting in a disorganized extracellular matrix and contributing to the development of DF.
