Abstract Nuclear factor-kappaB (NF-ĸB) plays a crucial role in both innate and adaptive immune systems, significantly influencing various physiological processes such as cell proliferation, migration, differentiation, survival, stemness. The function of NF-ĸB cancer progression response to chemotherapy has gained increasing attention. This review highlights the inflammation control, biological mechanisms, therapeutic implications treatment. is instrumental altering release inflammatory factors TNF-α, IL-6, IL-1β, which are key regulation carcinogenesis. Specifically, conditions including colitis, upregulation can intensify inflammation, potentially leading development colorectal cancer. Its pivotal extends regulating tumor microenvironment, impacting components macrophages, fibroblasts, T cells, natural killer cells. influences tumorigenesis dampen anti-tumor responses. Additionally, modulates death notably by inhibiting apoptosis ferroptosis. It also dual stimulating or suppressing autophagy cancers. Beyond these functions, controlling stem fostering angiogenesis, metastatic potential through EMT induction, reducing sensitivity radiotherapy. Given its oncogenic capabilities, research focused on products small molecule compounds that suppress NF-ĸB, offering promising avenues for therapy.

Inflammation is a vital defense mechanism, creating hostile conditions for pathogens, preventing the spread of tissue infection and repairing damaged tissues in humans animals. However, when inflammation resolution delayed or compromised as result its misregulation, process proceeds from acute phase to chronic inflammation, leading development various illnesses. It proven that redox balance disturbances oxidative stress are among major factors inducing NF-κB over-inflammation. Therefore, anti-inflammatory properties natural antioxidants have been widely tested vitro vivo systems. Accumulating evidence indicates silymarin (SM) main constituent silibinin/silybin (SB) great potential an anti-inflammation agent. The mechanism SM/SB action attributed inhibition TLR4/NF-κB-mediated signaling pathways downregulated expression pro-inflammatory mediators, including TNF-α, IL-1β, IL-6, IL-12, IL-23, CCL4, CXCL10, etc. Of note, same model systems, was able upregulate cytokines (IL-4, IL-10, IL-13, TGF-β, etc.) lipid mediators involved inflammation. inflammatory were clearly demonstrated systems based on immune (macrophages monocytes) non-immune (epithelial, skin, bone, connective cancer) cells.

Abstract Background Chronic inflammation has been shown to promote cancer progression. Rosacea is indeed a long‐term inflammatory skin condition and had reported link with increased risk for several types of malignancies, but evidence causality lacking. Objectives To systematically estimate the causal relationship between rosacea cancer, including cutaneous malignant melanoma (CMM), squamous cell carcinoma (cSCC), basal (BCC), actinic keratosis (AK), thyroid breast glioma hepatic as well explore potential underlying pathogenesis. Methods We conducted bidirectional two‐sample Mendelian randomization study probe relationships cancer. Instrumental variables were established using genome‐wide significant single nucleotide polymorphisms associated cancers. The assessment was carried out through multiple methods, robustness results evaluated via sensitivity analyses. Results There no indication effects on CMM ( p ivw = 0.71), cSCC 0.45), BCC 0.90), AK 0.73), 0.59), 0.15), 0.07), genetic an susceptibility human epidermal growth factor receptor (HER)‐negative neoplasm (odds ratio [OR], 1.10; 95% confidence interval [CI], 1.02–1.18; 0.01).

The tumor microenvironment (TME) provides essential conditions for the occurrence, invasion, and spread of cancer cells. Initial research has uncovered immunosuppressive properties TME, which include low oxygen levels (hypoxia), acidic (low pH), increased interstitial pressure, heightened permeability vasculature, an inflammatory microenvironment. presence various components leads to immune evasion affects immunotherapy efficacy. This indicates potential value targeting TME in immunotherapy. Therefore, remodeling become effective method enhancing host responses against tumors. In this study, we elaborate on characteristics composition how it weakens surveillance summarize targeted therapeutic strategies regulating TME.

Clinical Epigenetics, Год журнала: 2025, Номер 17(1)

Опубликована: Янв. 16, 2025

Abstract Background IgG4-related cholangitis (IgG4-SC) and primary sclerosing (PSC) are chronic fibro-inflammatory hepatobiliary conditions, with genetic, environmental, immunologic risk factors, in which epigenetic alterations may provide insights into pathophysiology novel biomarkers. This study is the first to assess methylation signatures IgG4-SC. Results Whole blood DNA profiling genotyping was performed 264 individuals; 47 IgG4-SC, 65 PSC, 64 ulcerative colitis (UC), 88 healthy controls. We identified 19 significant differences between IgG4-SC controls 38 PSC shared 8 probes. Inflammatory genes (including CEP97 , IFNAR1 TXK HERC6 C5orf36 PYY MTRNR2L1 ) were predominantly involved dysregulated methylation. Epigenetic age acceleration observed patients but not those or UC. meQTL analyses identify genetic determinants of revealed a strong human leucocyte antigen (HLA) signal both ( HLA-DQB2 HLA-DPA1 HLA-F HLA-DRA ). Conclusions biological providing disease pathogenesis, highlight role variation especially within HLA region shaping methylome.
