Nuclear factor-kappaB (NF-κB) is a pleiotropic, evolutionarily conserved transcription factor family that plays a central role in regulating immune responses, inflammation, cell survival, and apoptosis. Great strides have been made in the past three decades to understand the role of NF-κB in physiological and pathological conditions. Carcinogenesis is associated with constitutive activation of NF-κB that promotes tumor cell proliferation, angiogenesis, and apoptosis evasion. NF-κB is ubiquitously expressed, however, its activity is under tight regulation by inhibitors of the pathway and through multiple posttranslational modifications. -GlcNAcylation is a dynamic posttranslational modification that controls NF-κB-dependent transactivation. -GlcNAcylation acts as a nutrient-dependent rheostat of cellular signaling. Increased uptake of glucose and glutamine by cancer cells enhances NF-κB -GlcNAcylation. Growing evidence indicates that -GlcNAcylation of NF-κB is a key molecular mechanism that regulates cancer cell proliferation, survival and metastasis and acts as link between inflammation and cancer. In this review, we are attempting to summarize the current understanding of the cohesive role of NF-κB O-GlcNAcylation in inflammation and cancer.
Osteoarthritis (OA) is a degenerative joint disease that primarily affects the elderly worldwide. It is characterized by local inflammation, which can be targeted therapeutically using natural anti-inflammatory compounds such as curcumin. This scoping review explores the therapeutic effects and mechanisms of curcumin in OA management.
Background: Chemotherapy-induced mucositis (CIM) significantly impacts quality of life and reduces survival in patients treated with specific chemotherapeutic agents. However, effective clinical treatments for CIM remain limited. Intravenous immunoglobulin (IVIg), a therapeutic derived from pooled human plasma, is widely used to treat inflammatory diseases.
Cyclooxygenase-2 (COX-2) plays a crucial role in inflammation and has been implicated in cancer development. Understanding the behavior of COX-2 in different cellular contexts is essential for developing targeted therapeutic strategies. In this study, we investigate the fluorescence spectrum of a fluorogenic probe, NANQ-IMC6, when bound to the active site of human COX-2 in both its monomeric and homodimeric forms.
Background: Chronic hepatitis B virus (HBV) infection is a common but underdiagnosed and undertreated health condition and is the leading cause of hepatocellular carcinoma (HCC) worldwide. HBV (rated a Grade 1 carcinogen by the International Agency for Research on Cancer) drives the transformation of hepatocytes in multiple ways by inducing viral DNA integrations, genetic dysregulation, chromosomal translocations, chronic inflammation, and oncogenic pathways facilitated by some HBV proteins. Importantly, these mechanisms are active throughout all phases of HBV infection.
Background: Breast cancer is the leading cause of cancer-related deaths in women. Cytokines have been linked to various cancers, and both benign and malignant breast diseases are associated with inflammation. However, there is limited understanding of how the immune system's cytokine response varies among different subtypes of breast cancer.
