Published: March 26, 2024

Central neurological disorders are significant contributors to morbidity, mortality, and long-term disability globally in modern society. These encompass neurodegenerative diseases, ischemic brain traumatic injury, epilepsy, depression, more. The involved pathogenesis is notably intricate diverse. Ferroptosis neuroinflammation play pivotal roles elucidating the causes of cognitive impairment stemming from these diseases. Given concurrent occurrence ferroptosis due metabolic shifts such as iron ROS, well their critical central nervous disorders, investigation into co-regulatory mechanism has emerged a prominent area research. This paper delves mechanisms along with interrelationship. It specifically emphasizes core molecules within shared pathways governing neuroinflammation, including SIRT1, Nrf2, NF-κB, Cox-2, iNOS/NO·, how different immune cells structures contribute dysfunction through mechanisms. Researchers’ findings suggest that mutually promote each other may represent key factors progression disorders.

Cardiovascular disease: Mitochondrial dynamics and mitophagy crosstalk mechanisms with novel programmed cell death and macrophage polarisation

Pharmacological Research, Journal Year: 2024, Volume and Issue: 206, P. 107258 - 107258

Published: June 21, 2024

Several cardiovascular illnesses are associated with aberrant activation of cellular pyroptosis, ferroptosis, necroptosis, cuproptosis, disulfidptosis and macrophage polarisation as hallmarks contributing to vascular damage abnormal cardiac function. Meanwhile, these three novel forms dysfunction closely related mitochondrial homeostasis. Mitochondria the main organelles that supply energy maintain Mitochondrial stability is maintained through a series regulatory pathways, such fission, fusion mitophagy. Studies have shown (e.g., impaired dynamics mitophagy) promotes ROS production, leading oxidative stress, which induces M1 phenotypic polarisation. Therefore, an in-depth knowledge dynamic regulation mitochondria during necessary understand disease development. This paper systematically summarises impact changes in mitophagy on regulating dysfunctions promote understanding pathogenesis diseases provide corresponding theoretical references for treating diseases.

In defence of ferroptosis

Abstract Rampant phospholipid peroxidation initiated by iron causes ferroptosis unless this is restrained cellular defences. Ferroptosis increasingly implicated in a host of diseases, and unlike other cell death programs the physiological initiation conceived to occur not an endogenous executioner, but withdrawal guardians that otherwise constantly oppose induction. Here, we profile key ferroptotic defence strategies including regulation, modulation enzymes metabolite systems: glutathione reductase (GR), suppressor protein 1 (FSP1), NAD(P)H Quinone Dehydrogenase (NQO1), Dihydrofolate (DHFR), retinal reductases dehydrogenases (RDH) thioredoxin (TR). A common thread uniting all metabolites combat lipid during dependence on reductant, nicotinamide adenine dinucleotide phosphate (NADPH). We will outline how cells control central carbon metabolism produce NADPH necessary precursors defend against ferroptosis. Subsequently discuss evidence for dysregulation different disease contexts glucose-6-phosphate dehydrogenase deficiency, cancer neurodegeneration. Finally, several anti-ferroptosis therapeutic spanning use radical trapping agents, dependent redox support highlight current landscape clinical trials focusing

Dinuclear Dicationic Iridium Complexes for Highly Synergistic Photodynamic and Photothermal Therapy to Chemoresistant Cancer

Inorganic Chemistry, Journal Year: 2025, Volume and Issue: unknown

Published: Jan. 7, 2025

A series of dinuclear Ir(III) complexes have been constructed for enhanced photodynamic and photothermal therapy (PDT PTT) cisplatin-resistant non-small-cell lung cancer. They enter cells via caveolar endocytosis, target mitochondria but not nuclear, generate both singlet oxygen superoxide anion, release heat when exposed to infrared (IR) irradiation, thus inducing reactive species (ROS)-associated cell disruption thermal ablation. The IR-generated ROS can further activate caspases, triggering apoptosis. Additionally, the deplete intracellular glutathione, lead lipid peroxidation, induce ferroptosis. selected complex

Ferroptosis and pyroptosis are connected through autophagy: a new perspective of overcoming drug resistance

Molecular Cancer, Journal Year: 2025, Volume and Issue: 24(1)

Drug resistance is a common challenge in clinical tumor treatment. A reduction drug sensitivity of cells often accompanied by an increase autophagy levels, leading to autophagy-related resistance. The effectiveness combining chemotherapy drugs with inducers/inhibitors has been widely confirmed, but the mechanisms are still unclear. Ferroptosis and pyroptosis can be affected various types autophagy. Therefore, ferroptosis have crosstalk via autophagy, potentially switch cell death under certain conditions. As two forms inflammatory programmed death, different effects on inflammation, cGAS-STING signaling pathway also involved. it plays important role progression some chronic diseases. This review discusses relationship between pyroptosis, attempts uncover reasons behind evasion nature

Ferroptosis, characterized by iron-dependent lipid peroxidation, emerges as a promising avenue for hepatocellular carcinoma (HCC) intervention due to its tumor susceptibility. RNA N6-methyladenosine (m6A) modification has been involved in several types of regulated cell death. However, the roles and molecular mechanisms m6A-related regulators HCC ferroptosis remain unclear. By examining series m6A enzymes upon induction or inhibition, we identified METTL16 novel ferroptotic repressor cells.
