Figure 1: The heme/HO-1 system. Free heme is a reactive Fe compound that can catalyze, through the Fenton reaction, the formation of cytotoxic hydroxyl radical (OH.) from hydrogen peroxide (H2O2). Eli...

Figure 2: Transcriptional regulation of HMOX1. The rate of HMOX1 transcription can be induced by heme as well as by a variety of other agonists (1-n) recognized by specific receptors (1-n). These trig...

Figure 3: Cytoprotective effects of HO-1. Upon engagement, tumor necrosis factor receptor 1 (TNFR-1) induces the formation of multiprotein complex I, which activates the nuclear factor kappa B (NF-κB)...

Figure 4: Free heme sensitization to TNF-mediated programmed cell death (154). (a) When exposed to ROS, some hemoproteins can release their prosthetic heme groups. These act as pro-oxidant catalysts t...

Figure 5: Cellular free heme regulation. Free heme can gain intracellular access via different mechanisms, including through endocytosis of hemoproteins, a process linked to intracellular heme import ...

Figure 6: Systemic regulation of free heme. Under homeostasis, cell-free Hb released from red blood cells is scavenged by haptoglobin. Under pathologic conditions associated with hemolysis, the protec...

Figure 1: Domain architecture and comparison of host cell receptors (hACE2 and hDPP4), SARS-CoV, and SARS-CoV-2. (a) Domain organization of the SARS-CoV and SARS-CoV-2 S-glycoprotein and host cell rec...

Figure 1: Intubation and extubation timelines for self-poisoning with several particular OP insecticides. (a) Time to first intubation according to OP insecticide ingested, showing marked differences ...

Figure 2: Structure of representative OP insecticides. The figure demonstrates (a,c,f) thions (P=S) and (b,d,e) oxons (P=O), as well as (d) dimethoxy, (a,b,c) diethoxy, and (e,f) S-alkyl OP insecticid...

Figure 3: Inhibition, reactivation, and aging of AChE. A dimethoxy-phosphorylated OP oxon (methyl paraoxon) inhibits AChE by phosphorylating the serine hydroxyl group at the enzyme's active site (reac...

Figure 4: Effect of nebulized salbutamol on peripheral blood oxygen saturations in OP insecticide self-poisoned patients. (a) Mean (SEM) oxygen saturations of patients receiving no salbutamol (No Salb...

Figure 1: Versatile reactive cysteine thiol reactions. (a) Biochemistry of reactive cysteine thiols. Reactive cysteine thiols exist as thiolate anions and are prone to oxidation by reactive oxygen and...

Figure 2: Domain structure and activation mechanism. (a) Domain structures of Nrf2, Keap1, and small Mafs F, G, and K. (b) Secondary structure of Neh2. (c) Model for activation of Nrf2. Abbreviations:...
