Nrf2 and Ferroptosis: A New Research Direction for Ischemic Stroke
Cell Mol Neurobiol. 2023 Sep 20. doi: 10.1007/s10571-023-01411-y. Online ahead of print.ABSTRACTIschemic stroke (IS) is one of the leading causes of death and morbidity worldwide. As a novel form of cell death, ferroptosis is an important mechanism of ischemic stroke. Nuclear factor E2-related factor 2 (Nrf2) is the primary regulator of cellular antioxidant response. In addition to alleviating ischemic stroke nerve damage by reducing oxidative stress, Nrf2 regulates genes associated with ferroptosis, suggesting that Nrf2 may inhibit ferroptosis after ischemic stroke. However, the specific pathway of Nrf2 on ferroptosis in ...

Association of Ferroptosis with Severity and Outcomes in Acute Ischemic Stroke Patients Undergoing Endovascular Thrombectomy: A Case-control Study
AbstractFerroptosis, an iron-dependent form of cell death, is characterized by intracellular accumulation of iron and reactive oxygen species-induced lipid peroxidation. Animal experiments have shown the important roles of ferroptosis in ischemic stroke, but the evidence in human stroke is insufficient. This prospective study evaluated the associations between plasma ferroptosis biomarkers at hyperacute stage and long-term outcomes in patients with acute ischemic stroke undergoing endovascular thrombectomy (EVT). The plasma samples were collected immediately before and after EVT (T1 and T2) and at 24  h (T3) for the 126 s...

Haem Iron Intake Is Associated with Increased Major Adverse Cardiovascular Events, All-Cause Mortality, Congestive Cardiac Failure, and Coronary Revascularisation in Older Men: The Concord Health and Ageing in Men Project
ConclusionHigher haem iron intake was independently associated with increased risks of five-point MACE, four-point MACE excluding all-cause mortality, all-cause mortality, CCF, and coronary revascularisation in older men over 5 years.

Iron, Ferroptosis, and Ischemic Stroke
AbstractOver 30 million people suffer from the consequences of ischemic stroke. The precise molecular mechanism of neuronal damage during ischemic stroke remains unclear; therefore, the effective treatment of post-ischemic stroke remains a critical challenge. Recently, iron has emerged as a crucial factor in post-reperfusion injuries, participating in cell peroxidation, excitotoxicity, and a distinctive cell death pathway, namely ferroptosis. Since iron is tightly regulated in the brain and important for brain functions, the imbalance of its metabolism, including its overload and deficiency, has been shown to impact ischem...

MRI for all: Cheap portable scanners aim to revolutionize medical imaging
.news-article__hero--featured .parallax__element{ object-position: 47% 50%; -o-object-position: 47% 50%; } The patient, a man in his 70s with a shock of silver hair, lies in the neuro intensive care unit (neuro ICU) at Yale New Haven Hospital. Looking at him, you’d never know that a few days earlier a tumor was removed from his pituitary gland. The operation didn’t leave a mark because, as is standard, surgeons reached the tumor through his nose. He chats cheerfully with a pair of research associates who have come to check his progress with a new and potentially revolutionary device they are testing. The cylind...

Role of lipocalin 2 in stroke
Neurobiol Dis. 2023 Feb 16:106044. doi: 10.1016/j.nbd.2023.106044. Online ahead of print.ABSTRACTStroke is the second leading cause of death worldwide; however, the treatment choices available to neurologists are limited in clinical practice. Lipocalin 2 (LCN2) is a secreted protein, belonging to the lipocalin superfamily, with multiple biological functions in mediating innate immune response, inflammatory response, iron-homeostasis, cell migration and differentiation, energy metabolism, and other processes in the body. LCN2 is expressed at low levels in the brain under normal physiological conditions, but its expression i...

Regulation of the p53 ‑mediated ferroptosis signaling pathway in cerebral ischemia stroke (Review)
Exp Ther Med. 2023 Jan 26;25(3):113. doi: 10.3892/etm.2023.11812. eCollection 2023 Mar.ABSTRACTStroke is one of the most threatening diseases worldwide, particularly in countries with larger populations; it is associated with high morbidity, mortality and disability rates. As a result, extensive research efforts are being made to address these issues. Stroke can include either hemorrhagic stroke (blood vessel ruptures) or ischemic stroke (blockage of an artery). Whilst the incidence of stroke is higher in the elderly population (≥65), it is also increasing in the younger population. Ischemic stroke accounts for ~85% of a...

Elabela-APJ axis attenuates cerebral ischemia/reperfusion injury by inhibiting neuronal ferroptosis
Free Radic Biol Med. 2023 Jan 18:S0891-5849(23)00009-6. doi: 10.1016/j.freeradbiomed.2023.01.008. Online ahead of print.ABSTRACTFerroptosis is a form of non-apoptotic cell death caused by iron-dependent peroxidation of lipids. It contributes to ischemic stroke-induced neuronal damage. Elabela (ELA), a novel endogenous ligand for Apelin receptor (APJ), regulates oxidative stress and exerts a protective role in cardiovascular disease. However, the effect of ELA-APJ axis on cellular ferroptosis in cerebral ischemia/reperfusion (I/R) remains elusive. The present study showed that ELA and APJ were expressed on neurons and incre...
