Summary: In the progression of atherosclerotic plaque, the death of foam cells accelerates plaque development. While Nrf2 has been considered a major regulator of antioxidants, recent studies have shown that insufficient autophagy can deactivate Nrf2-mediated defense, leading to ferroptosis.

Summary: Atherosclerosis, the underlying cause of cardiovascular diseases and high mortality rates, progresses with the formation of atherosclerotic plaques due to oxidative stress. Strategies aimed at reducing oxidative damage, including the use of antioxidant molecules such as Nrf2 and HO-1, have been studied to inhibit the progression of atherosclerosis.

Summary: This study investigated the role and mechanism of beta-hydroxybutyrate dehydrogenase 1 (Bdh1) in regulating macrophage oxidative stress in diabetes-induced atherosclerosis (AS). The results showed that Bdh1 expression was decreased in patients with diabetes-induced AS, HG-treated macrophages, and diabetic Apoe(-/-) mice. AAV-mediated Bdh1 overexpression attenuated aortic plaque formation in diabetic Apoe(-/-) mice, while silencing of Bdh1 increased reactive oxygen species (ROS) production and an inflammatory response in macrophages.

Summary: This study investigated the genome-wide effects of oxidized phospholipids on transcriptional gene regulation in endothelial cells, focusing on the role of miRNAs and NRF2 transcription factor. The results showed that NRF2 plays a key role in up-regulated transcripts and transcriptional initiation in response to oxidized phospholipids. Furthermore, NRF2 was identified as a novel regulator of over 100 endothelial pri-miRNAs, with miR-21-5p and miR-100-5p demonstrating opposing roles in gene expressions and potential correlation with the severity of coronary artery disease.

Summary: Oxidative stress and lipid metabolism disorder caused by estrogen deficiency contribute to postmenopausal atherosclerosis. This study used ovariectomized female ApoE(-/-) mice fed with a high-fat diet to simulate postmenopausal atherosclerosis. The progression of atherosclerosis was accelerated in these mice, accompanied by increased indicators of ferroptosis. Estradiol and a ferroptosis inhibitor showed protective effects against atherosclerosis and inhibited lipid peroxidation and iron deposition in endothelial cells. Additionally, estradiol exhibited anti-ferroptosis effects by improving mitochondrial dysfunction and upregulating GPX4 expression. NRF2 inhibition attenuated the protective effects of estradiol against ferroptosis. This research highlights the role of endothelial cell ferroptosis in postmenopausal atherosclerosis and the protective effects of NRF2/GPX4 pathway activation by estradiol.

Summary: Excessive oxidative stress and decreased antioxidant capacity of macrophages are key factors in the transformation of macrophages to foam cells, a crucial event in the progression of atherosclerosis. The analog of lipoxin A(4), BML-111, can attenuate HF diet-induced atherosclerosis by activating Nrf2, independent of a specific LXA(4) receptor. In addition, BML-111 can inhibit the promotion of MDA level, increase HDL level, and decrease levels of IL-1, MCP-1, IL-6, VCAM, ICAM, and TNF-alpha in the aorta. In vitro experiments also showed that LXA(4) can inhibit the transformation of THP-1 cells to foam cells through the Nrf2 pathway.

Summary: This study analyzed the transcriptome of different Nrf2-deficient macrophage subpopulations from murine atherosclerotic aortas. The results showed that Nrf2 deficiency led to subtype-specific transcriptomic changes associated with inflammation, iron homeostasis, and cell injury or death pathways.

Summary: Cadmium telluride quantum dots (CdTe QDs) trigger inflammatory responses and activate macrophages in mice, and the mechanism behind the activation of macrophages to overexpress IL-1 beta and IL-6 is explored. The study reveals that CdTe QDs induce ferroptosis in macrophages. Activation of ferritinophagy through a decrease in NRF2 and phosphorylation of ERK1/2 plays a key role in initiating ferroptosis in macrophages.

Summary: This study demonstrates that PGF(2 alpha) can enhance the expression of antioxidant genes through the FP receptor-ERK-Nrf2 signaling pathway, thereby suppressing 6-OHDA-induced neuronal cell death. The findings suggest that the FP receptor may be a potential therapeutic target for ROS-mediated neurodegeneration.

Summary: This study reveals that neuropeptide Y (NPY) can modulate the phenotype and functions of human macrophages, promoting their transition to a reparative phenotype that has therapeutic effects on atherosclerosis. NPY reduces lipid droplet accumulation and enhances autophagosome formation in macrophages. Additionally, NPY increases the activation of the antioxidant signaling pathway in macrophages, protecting cells from further damage in the inflammatory pathway.

Summary: Doublecortin-like kinase 1 (DCLK1) is a significant prooncogenic factor that is strongly associated with the malignant progression and clinical prognosis of various cancers. DCLK1 plays important roles in stem cell marker regulation, tumor cell reprogramming, and immune evasion. However, the exact biological functions of DCLK1, especially the disparities between its alpha- and beta-form transcripts in cancer progression, remain ambiguous.
