Ulcerative colitis (UC) is an inflammatory bowel disease, and characterized by the diffuse inflammation ulceration in colon rectum mucosa, even extending to caecum. Epigenetic modifications, including DNA methylations, histone modifications non-coding RNAs, are implicated differentiation, maturation, functional modulation of multiple immune non-immune cell types, influenced altered various chronic diseases, UC. Here we review relevant studies revealing differential epigenetic features UC, summarize current knowledge about immunopathogenesis UC through regulation signaling networks, regarding methylation, modification, miRNAs lncRNAs. We also discuss epigenetic-associated therapeutic strategies for alleviation treatment which will provide insights intervene immunopathological process view regulation.

Oxidative stress (OS) is a key factor in the generation of various pathophysiological conditions. Nuclear erythroid 2 (NF-E2)-related (Nrf2) major transcriptional regulator antioxidant reactions. Heme oxygenase-1 (HO-1), gene regulated by Nrf2, one most critical cytoprotective molecules. In recent years, Nrf2/HO-1 has received widespread attention as regulatory pathway for intracellular defense against oxidative stress. It considered potential target treatment inflammatory bowel disease (IBD). This review highlights mechanism action and therapeutic significance IBD complications (intestinal fibrosis colorectal cancer (CRC)), well phytochemicals targeting IBD. The results suggest that effects on mainly involve following aspects: (1) Controlling to reduce intestinal inflammation injury; (2) Regulation flora repair mucosal barrier; (3) Prevention ferroptosis epithelial cells. However, due complex role Nrf2/HO-1, more nuanced understanding exact mechanisms involved way forward future.

Ulcerative colitis (UC), a chronic idiopathic inflammatory bowel disease (IBD), presents with limited current drug treatment options. Consequently, the search for safe and effective UC prevention is imperative. Our prior studies have demonstrated that phenolic compound p-Hydroxybenzaldehyde (HD) from Nostoc commune, effectively mitigates intestinal inflammation. However, mechanisms underlying HD's anti-inflammatory effects remain unclear.

Ulcerative colitis (UC) is a recurring inflammatory bowel disease, in which oxidative stress plays role its progression, and regulation of the oxidative/antioxidative balance has been suggested as potential target for treatment UC. The aim this study was to evaluate protective effect andrographolide against UC antioxidant properties by modulating nuclear factor erythroid 2-related 2 (Nrf2)/heme oxygenase-1 (HO-1) pathway. Dextran sulfate sodium (DSS) -induced mice LPS-induced HT29 cell model were established uncover mechanisms andrographolide.

Colorectal cancer (CRC), as the third most common bisexual worldwide, requires urgent research on its underlying mechanisms and intervention methods. NRF2 is an important transcription factor involved in regulation of redox homeostasis, protein degradation, DNA repair, other processes, playing role cancer. In recent years, complex CRC has been continuously revealed: one hand, it exhibits a chemopreventive effect by protecting normal cells from oxidative stress, also protective malignant cells. Therefore, this article explores dual related signaling pathways CRC, including their chemical properties promoting effects occurrence, development, metastasis, chemotherapy resistance CRC. addition, focuses exploring ferroptosis, well drug modulators (activators inhibitors) targeting natural products, compounds, traditional Chinese medicine formulations.
