    Article Title: Inhibition of aerobic glycolysis suppresses ferroptosis via activation of the AMPK-FoxO3a pathway in epileptic rats.
    Article Snippet: 1 Department of Neurology, The Affiliated Hospital of Qingdao University, Qingdao 266100, Shandong Province, China 2 Department of Neurology, The First Affiliated Hospital, Jiangxi Medical College, Nanchang University, Nanchang 330006, China 3 Department of Clinical Pharmacy, Qingdao Municipal Hospital, Qingdao 266071, Shandong Province, China Abstract Background Ferroptosis has recently been implicated in seizure-induced neurodegeneration, whereas enhanced aerobic glycolysis during seizures may aggravate oxidative stress and ferroptotic damage.. This study investigated whether inhibition of aerobic glycolysis suppresses ferroptosis through activation of the AMP-activated protein kinase (AMPK)–Forkhead box O3a (FoxO3a) signaling pathway in epileptic rats.. Methods and results A pilocarpine (PILO)-induced epilepsy model was established in male Wistar rats.

    Article Title: miR-495-3p promotes chronic obstructive pulmonary disease by activating ferroptosis in lung epithelial cells through regulation of the ETS1/GPX4 axis
    Article Snippet: .. To determine the role of GPX4 in miR-495-3p-regulated CSE-induced cell injury, after transfection with the miR-495-3p antagomir, the transfection medium was discarded and replaced with fresh complete medium containing 100 nM RSL3 (HY-100218 A; MedChemExpress, USA), followed by incubation for 2 h before CSE stimulation. .. To investigate whether miR-495-3p inhibits GPX4 transcription by targeting ETS1, BEAS-2B cells were transfected with 50 nmol/L miR-495-3p agomir (HY-R01472A; MedChemExpress, USA) and incubated for 24 h, with NC agomir as a control, to detect the binding between miR-495-3p and ETS1.

    Article Title: FGFR1 drives metabolic adaptation associated with temozolomide resistance in glioblastoma.
    Article Snippet: Therapy resistance is a major limitation in therapeutic efficacy for glioblastoma (GBM) patients, positioning GBM among the deadliest tumor types.. In this work, we have dissected resistance mechanisms in GBM, which resulted in the identification of FGFR1 pathway as a major controller of the signaling and metabolic rewiring associated to temozolomide (TMZ) resistance.. Hence, in FGFR1-positive, p53 WT GBM cells, FGFR1 controls a p53-mediated cell cycle arrest to allow DNA repair in response to TMZ.

    Article Title: Bazedoxifene rescues hepatocytes from chemically induced oxidative ferroptotic injury in vivo and in vitro by inhibiting protein disulfide isomerase

The membranes were then incubated with a horseradish peroxidase-conjugated secondary antibody (1:10000, SA00001-2, ProteinTech Group, Chicago, IL, USA) for 2 h. For the ubiquitination assay, the protein complexes were detected by western blotting using an anti-ubiquitin primary antibody (1:1000, 43124, Cell Signaling Technology, Danvers, MA, USA).
