The Award Committee makes selections from the 10 top-ranking articles published in Biological Psychiatry in the past year. NF-B regulates the expression of a large array of genes involved in different aspects of atherosclerotic pathogenesis.127 In vascular endothelial cells, NF-B mediates induction of pro-inflammatory cytokines, chemotactic factors and adhesion molecules, thereby promoting monocyte recruitment and disease progression.127131 Conditional deletion of NEMO or transgenic expression of a degradation-resistant IB in endothelial cells inhibits chemokine expression and monocyte recruitment, coupled with reduced disease severity of atherosclerosis, in ApoE-deficient mice fed with a cholesterol-rich diet.129 NF-B also functions in myeloid cells to promote inflammatory gene expression and conversion of macrophages into foam cells.127 Transgenic expression of a non-degradable IB in macrophages reduces lipid loading and foam-cell formation, whereas myeloid cell-specific IB deletion sensitizes atherosclerosis development in LDL receptor-deficient mice.132,133 In line with these findings, myeloid cell-specific deletion of IKK reduces atherosclerotic lesion areas in LDL receptor-deficient mice fed with high-fat diet, which is associated with attenuated activities of macrophages in inflammatory gene expression, adhesion, migration and lipid uptake.134 Surprisingly, however, an earlier study suggests that deletion of IKK in myeloid cells increases atherosclerotic lesion sizes in the LDL receptor-deficient mice.134,135 The reason for such a discrepancy is unclear, although it could be due to the differential experimental approaches used in these two different studies. 23, 41534164 (2019).

Constitutive activation of NF-B in myeloid cells, as a result of IB deletion using the LysM-Cre system, causes more severe CNS inflammation and clinical scores in myelin oligodendrocyte glycoprotein-induced EAE,121 whereas myeloid cell-specific deletion of IKK inhibits EAE induction associated with impaired generation of inflammatory Th1 and Th17 cells.122 NF-B also functions in the CNS to regulate neuroinflammation, since conditional deletion of NEMO or IKK using Nes-Cre, which is specific for neuronal cells including neurons, astrocytes and oligodendrocytes, partially inhibits EAE induction.123 Furthermore, NF-B inhibition in astrocytes via transgenic expression of a degradation-resistant form of IB (IB-dn) inhibits inflammatory cytokine expression and reduces the disease severity in EAE.124,125.

ALA, as described before, can raise glutathione intracellularly, and it has a protective effect on ischemia-reperfusion injury in a variety of clinical conditions, such as simultaneous kidney-pancreas transplantation,273 human liver transplantation,274 and liver resection.275 The levels of lipid peroxide is markedly increased, while the levels of GSH and GPx4 are significantly reduced in rodent models of ischemic stroke, and carvacrol protected hippocampal neurons by increasing GPx4 expression.276 Knockout of GPx4 induces kidney failure in mice, which can be inhibited by lipid peroxidation inhibitors.80 Similarly, cardiac IRI can be alleviated by mitochondria-specific overexpression of GPx4.277, Intriguingly, the regulation of iron and lipid peroxidation can impact ferroptosis sensitivity, and accumulated evidence shows that the regulation of these two vital factors can affect IRI by controlling the ferroptosis (Fig. Kidney Int.

Pharmacological inhibition of cystine-glutamate exchange induces endoplasmic reticulum stress and ferroptosis. To recoup this outlay pharmaceutical companies may do a number of things:[32].

GPx4, a selenocysteine-containing, and glutathione-dependent enzyme, catalyzes the reduction of specific lipid hydroperoxides into lipid alcohols.83 GPx4 belongs to the family of Glutathione peroxidases (GPxs),84 but in contrast to other GPxs, GPx4 lacks a dimerization interface and exists as a monomeric species.85 GPx4 is a multifunctional protein capable of reducing peroxidized lipids either in free form or in complex with lipids such as PLs, with proteins such as lipoproteins or within membranes.86 This characteristic of reducing lipid peroxidation within membrane lipids determines its predominant role in preventing ferroptosis (Fig. MAPK1 (Mitogen-Activated Protein Kinase 1) is a Protein Coding gene.

USA 94, 55315534 (1997). Phosphorylation sites are crucial for proteins and their transportation and functions. On the other hand, the TGF- signaling pathway can also disturb the immune system to induce immune evasion. An increased KRAS mutation and SMAD mutation in PDAC patients drive early tumorigenesis and metastasis. Kch, E.-M. et al. While the cell may simply respond by increasing or decreasing the metabolic process through increased or decreased intake of glucose, the response may also involve the regulation of gene expression where certain genes are activated or de-activated depending on certain processes. 2016;54:11427.

Li, L. et al. However, there are still limited treatment strategies for these diseases.209 Therefore, it is urgent to impel further exploration of the relationship between pathological characteristics, disease mechanism, and neuronal death.

In 2018, it was shown that tau overexpression and hyperphosphorylation can induce neuronal loss via ferroptosis, and ALA supplementation effectively inhibited cognitive decline through reducing tau-induced iron overload, lipid peroxidation, and upregulating GPx4 expression in P301S tau transgenic mice.243 Moreover, a targeted mutation of GPx4 (selenocysteine to cysteine substitution) or GPx4 conditional deletion in neurons causes neuronal toxicity and rapid neuronal death in mice, which are accompanied by multiple ferroptotic characteristics.22,92 GPx4 is also critical for maturation and survival of photoreceptor cells; photoreceptor-specific rapidly underwent severe degeneration and completely disappeared by conditional knock-out GPx4.244 Targeted conditional knockout of GPx4 in forebrain neurons of adult mice causes AD-like cognitive impairments and neurodegeneration that can be attenuated by ferroptosis inhibitors.245 Also, the expression of GPx4 might play a neuroprotective role in PD pathology.246 It is shown that GPx4 colocalizes with AS-positive nigral Lewy bodies and dystrophic TH-positive fibers in the putamen, and it is increased relative to cell density, probably because of an increase in survival of cells expressing GPx4.246 There is a correlation between selenium level, a key factor for GPx4 activity, and susceptibility to ferroptosis.247 In AD patients, the selenium level can be related to the pathological progress of the disease.248,249 The treatment of selenium attenuates a beta production by reduced 4-HNE-induced transcription of beta-secretase (BACE1) and protects against A-mediated toxicity in primary cultured neurons.250 In a paraquat-induced rat PD model, selenium feeding also can reduce bradykinesia and DNA damage.251 Depletion of DJ-1, a known cause of early-onset autosomal recessive Parkinsons disease,252 can also increase the sensitivity of neurons to ferroptosis by markedly reduce GSH levels through inhibition of the transsulfuration pathway.99. Despite SMAD pathways, TGF- also promotes HSC activation through non-SMAD pathways (MAPK, ERK, p38, and JNK pathways). Jovanovi J, Iqbal S, Jensen S, Mardon H, Handford P.

Cysteine is the most limiting amino acid for GSH synthesis and inhibition of its import through the system \({\mathrm{X}}_c^-\) is sufficient to trigger ferroptosis in vitro.6 System \({\mathrm{X}}_c^-\) is a cystine/glutamate antiporter that facilitates the exchange of cystine and glutamate across the plasma membrane.1,15 Upon transport inside the cell, cystine is reduced to cysteine by GSH or thioredoxin reductase 1 (TXNRD1).95 Cysteine is a semi essential amino acid as it can be produced from methionine through the transsulfuration pathway converting methionine to homocysteine, cystathionine, and in a final step to cysteine.96 It has been shown that hepatocellular carcinoma cells are resistant to sorafenib, a novel multi-targeted oral drug for the treatment of tumors,97 which is acquired through transcriptional regulation of genes involved in lipid ROS and iron metabolism.98 Recently, inhibition of DJ-1 (also known as PARK7-parkinsonism-associated deglycase) has been shown to enhance the sensitivity of tumor cells to ferroptosis induced by sorafenib and evaluated the antitumor activity of erastin in a xenograft nude mouse model via inhibition of the transsulfuration pathway and limiting the supply of cysteine.99 P53, a tumor suppressor gene, is mutated in at least 80% of the most difficult-to-treat cancers, such as high-grade serous ovarian cancers, or triple-negative breast cancers.100 Cell-cycle arrest, apoptosis, and senescence are widely accepted as the major mechanisms by which p53 inhibits tumor formation. 52, 18201827 (2012).
