Summary: Ordinary differential equations are commonly used for mathematical modeling in biological systems. Identifying cell-type specific mechanisms is crucial in building useful models and understanding biological processes. Existing regularization techniques are inconsistent when analyzing more than two cell types. To address this, the paper proposes incorporating the clustered LASSO into ordinary differential equation modeling by penalizing pairwise differences of fold-change parameters. This approach renders the results independent of the reference cell type. The paper demonstrates the performance of the method using realistic biological models and synthetic data, and also applies it to published biological models with experimental data.

Summary: This study aimed to investigate the role and mechanisms of TRIM38 in myocardial ischemia/reperfusion (I/R) injury. The results showed that TRIM38 expression can alleviate inflammatory responses and oxidative stress, inhibit apoptosis, and attenuate cellular injury by suppressing the TAK1/NF-kappa B pathway activity.

Summary: The study found that TBBPA significantly induced proliferation of Ishikawa cells by activating NF-κB and mediating the upregulation of inflammatory cytokines through IκB' degradation. In vivo experiments confirmed the mechanism, suggesting that ubiquitin-mediated IκB' degradation and inflammatory response may serve as critical biomarkers for TBBPA-induced endometrial carcinoma.

Summary: Banana is an important fruit crop worldwide. In this study, an anthocyanin-rich extract from banana bract (BBA) was prepared and characterized. BBA showed antioxidant and anti-inflammatory activity in LPS-stimulated macrophage-like cells. The presence of phenolic compounds, flavonoids, and anthocyanin in BBA was identified. BBA increased endogenous antioxidants and inhibited the nuclear translocation of NF-kappaB under LPS-stimulated conditions, indicating its potential as an anti-inflammatory agent.

Summary: This study aimed to investigate the effects of PFOS exposure on atherosclerosis progression and the underlying mechanisms. The results showed that PFOS increased pulse wave velocity, intima-media thickness, aortic plaque burden, and levels of serum lipids and inflammatory cytokines. PFOS promoted M1 macrophage polarization and suppressed M2 macrophage polarization, leading to inflammation. NF-κB activation in macrophages was associated with this process. These findings highlight the role of PFOS in accelerating atherosclerosis progression through NF-κB-mediated inflammation.

Summary: Nuclear factor kappa B (NF-kappa B) is a dimeric transcription factor that regulates the expression of chemokines, cytokines, transcription factors, and regulatory proteins, playing a crucial role in inflammation and immunity. Understanding its specific roles in different cell types, tissues, and under different stimuli is important. This review focuses on the role of NF-kappa B in monocytes and macrophages, innate immune cells that exhibit high plasticity and adjust their functions against pathogens and cues from the environment. NF-kappa B activation in macrophages has significant implications in inflammatory diseases and its temporal dynamics are complex.

Summary: This study investigated the effects of acetate on cardiometabolic abnormalities associated with polycystic ovarian syndrome (PCOS) in a rat model. The results suggest that acetate protects against cardiac inflammation by suppressing PCSK9 and NF-kB-dependent mechanisms.

Summary: This study investigated the effects of diosgenin on periodontitis and found that it inhibited inflammatory responses and the activation of NF-kappa B pathway while promoting osteogenesis. Administering diosgenin to periodontitis rats also reduced the levels of inflammatory factors and NF-kappa B in gingival tissue, and promoted the expression of osteoblast-related genes. These findings suggest that diosgenin may be a potential therapeutic strategy for treating periodontitis in the future.

Summary: Diabetic kidney disease (DKD) is a common complication of diabetes, and the understanding of its molecular mechanisms is still incomplete. A recent study found that the expression of deubiquitinating enzyme USP25 was significantly upregulated in the kidneys of diabetic mice, and its absence worsened diabetes-induced renal dysfunction and fibrosis.

Summary: Linear ubiquitination is an important protein modification that attaches a head-to-tail polyubiquitin chain to a substrate protein to mediate signaling pathways. It plays a critical role in various types of cancers, and dysregulation of linear ubiquitination may contribute to tumorigenesis and cancer development.

Summary: In this study, it was found that overexpression of TRIM47 is associated with tumor progression and poor prognosis in triple-negative breast cancer. The researchers demonstrated that TRIM47 directly interacts with BRCA1 and induces proteasome turnover of BRCA1, leading to a decrease in BRCA1 protein levels in TNBC. Additionally, TRIM47 overexpression confers sensitivity to the PARP inhibitor olaparib, while TRIM47 inhibition confers resistance to olaparib in TNBC. Overexpression of BRCA1 also increases resistance to olaparib in TRIM47-overexpression-induced PARP inhibition sensitivity. These findings suggest that targeting the TRIM47/BRCA1 axis may be a promising prognostic factor and therapeutic target for TNBC.

Summary: The expression of Receptor activator of NF-kappa B (RANK) is increased in podocytes of patients with diabetic nephropathy. Mouse models of podocyte-specific RANK depletion and overexpression showed that RANK depletion alleviated the development of kidney diseases, while RANK overexpression aggravated the condition. The findings suggest that RANK mediates the development of diabetic nephropathy by promoting glomerular oxidative stress and proinflammatory cytokine production.
