The basic leucine zipper transcription factor Nrf2 is the primary regulator of cellular oxidative stress. Activation of Nrf2 is regarded as a potential preventive and therapeutic strategy. However, aberrant hyperactivation of Nrf2 is found in a variety of cancers and promotes cancer progression and metastasis. Moreover, constitutive activation of Nrf2 confers cancer cells resistance to chemo- and radio-therapy. Thus, inhibiting Nrf2 could be a new therapeutic strategy for cancer. With the aim of accelerating the discovery and development of novel Nrf2 inhibitors, we summarize the biological and pathological functions of Nrf2 in cancer. Furthermore, the recent studies of small molecular Nrf2 inhibitors and potential Nrf2 inhibitory mechanisms are also summarized in this review.

4',5,6,7-tetrahydoxyisoflavone (6-hydroxygenistein, 6-OHG) is a hydroxylated derivative of genistein with excellent antioxidant activity, but whether 6-OHG can protect hypoxia-induced damage is unclear. The objective of current study was to evaluate the protective effect and underling mechanism of 6-OHG against hypoxia-induced injury via network pharmacology and cellular experiments. 6-OHG-related and hypoxia injury-related targets were screened by public databases.

The activation of acid-sensing ion channel 1a (ASIC1a) in response to extracellular acidification leads to an increase in extracellular calcium influx, thereby exacerbating the degeneration of articular chondrocytes in rheumatoid arthritis (RA). It has been suggested that the inhibition of extracellular calcium influx could potentially impede chondrocyte ferroptosis. The cystine transporter, solute carrier family 7 member 11 (SLC7A11), is recognized as a key regulator of ferroptosis.

Purpose: To investigate the effect of the SUMOylation inhibitor TAK981 on hydrogen peroxide (H2O2)-induced oxidative damage in human retinal pigment epithelial cells (ARPE-19) and its regulatory mechanism.
Methods: An oxidative damage model of ARPE-19 cells induced by H2O2 was established, and 1, 2, and 5 µM TAK981 solutions were administered for intervention respectively. Normal cells were used as the control group.

Cisplatin (CIS) is a broad-spectrum anticancer drug widely used in the clinic; however, one of its side effects is that it can cause intestinal damage such as loss of appetite, vomiting, and diarrhea in patients. Epigallocatechin gallate (EGCG) is one of the main active substances in green tea, which has the effects of antitumor multiple drug resistance, antioxidation, and antiinflammatory properties. The aim of this study was to explore the protective effect of EGCG on CIS-induced intestinal injury in rats.

Ischemic stroke, a severe cerebrovascular disease, is particularly prevalent among the elderly. Rsearch has indicated that histone deacetylases (HDACs) are pivotal in the pathogenesis of ischemic stroke. We introduce a novel HDACs inhibitor, HDI-1, as a potential therapeutic strategy for this condition.
