Thermal proteome profiling reveals distinct target selectivity for differentially oxidized oxysterols

ABSTRACT: The dataset contains mass spectrometric raw data from Thermal Proteomic Profiling experiments aimed to identify the protein targets of three A- and B-ring oxidized sterols (cholestane-3beta,5alfa,6beta-triol (CT), 7keto-cholesterol (7-KC), 4beta-hydroxycholesterol (4beta-HC) ) and a side-chain oxidized sterol (25-hydroxycholesterol (25-HC)). The dataset comprises the raw data for the 4 different oxysterols, measured on both oxysterol (compound) and DMSO (vehicle), each collected in 28 fractions. The experiments were performed in three independent replicates for each oxysterol (R1-R3).

Thermal Proteome Profiling Reveals Distinct Target Selectivity for Differentially Oxidized Oxysterols.

Rossetti Cecilia C Laraia Luca L

ACS chemical biology 20220628 7

Oxysterols are produced physiologically by many species; however, their distinct roles in regulating human physiology have not been studied systematically. The role of differing oxidation states and sites in mediating their biological functions is also unclear. As oxysterols have been associated with atherosclerosis, neurodegeneration, and cancer, a better understanding of their protein targets is desirable. To address this, we mapped the oxysterol interactome with three A- and B-ring oxidized s ...[more]

UVA and to UV-oxidized lipids proteomic regulation of the human keratinocytes

Project description:Ultraviolet light is the dominant environmental oxidative skin stressor and a major skin aging factor. We studied which oxidized phospholipid (OxPL) mediators Ultraviolet A (UVA) would generate in primary human keratinocytes (KC). Mass spectrometric analysis of the oxidized phospholipidome of KC immediately or 24h post stress revealed dynamic changes in abundance of 174 oxidized phosphocholine species. Exposure to UVA and to in vitro UVA - oxidized phospholipids both activated, on transcriptome and proteome level, NRF2/antioxidant response signaling and lipid metabolizing enzyme expression, whereas UVA additionally initiated the unfolded protein response (UPR). We identified Nupr1 as an upstream transcriptional regulator of UVA/OxPL mediated gene expression that is itself transcriptionally regulated by reactive lipids, which also aggregate and crosslink recombinant Nupr1 protein. Nupr1 governs the basal and stress regulated expression of cell cycle, redox reactive, autophagy- and lipid metabolizing genes in epidermal keratinocytes, making it a potential key factor in skin ROS responses, -aging and -pathology.

Hydrogen modulates signal transduction through manipulating oxidized phospholipid mediators

Project description:We have previously demonstrated that molecular hydrogen (H2) neutralizes hydroxyl radical (M-bM-^@M-"OH) in cultured-cells and protects cells and tissues against oxidative stress. Growing evidence has confirmed that H2-consumption exhibits preventive and therapeutic effects in patients with various diseases as well as model animals. Moreover, a small amount of H2 modulates signal transduction for regulating the expression of various genes; however, the primary target of H2 for exhibiting a variety of phenotypes was completely unknown. Here we show that H2 at low amounts manipulates oxidized phospholipid mediators to modulate Ca2+-signal transduction and gene expression. Gene expression was measured at 4 hours after exposure to phospholipid, PAPC or oxidized PAPC that had been air-oxidized for 3 days with 0, 1.3 or 5% H2. Three independent experiments were performed for each experiment.

Oxidized thioredoxin-1 restrains the NLRP1 inflammasome [mBMDM]

Project description:The danger signals that activate the NLRP1 inflammasome have yet to be firmly established. NLRP1 undergoes autoproteolysis to generate N-terminal (NT) and C-terminal (CT) fragment, which importantly, is a necessary step for its check-point regulation by the DPP9 ternary complex and the mechanistic activation of NLRP1 through functional degradation. Here, we report an added layer of regulatory complexity to NLRP1 activity, in the form of a repressive interaction that NLRP1 forms with the oxidized, but not reduced, form of thioredoxin-1 (TRX1). Loss of TRX1 destabilizes the NT fragment of NLRP1 and promotes enhanced inflammasome activation. The TRX1 interaction occurs through the NACHT-LRR of NLRP1 and requires nucleotide binding in its ATPase domain. In addition, we found that several patient-derived and ATPase-inactivating mutations in the NACHT-LRR region hyperactive the inflammasome by destabilize protein folding and are also shown to abrogate TRX1 binding. Thus, NLRP1 appears to detect intracellular reductive stress through a decrease in the fraction of intracellular oxidized TRX1, which enhances protein disorder, leading to inflammasome signaling. These findings link the cellular redox environment to NLRP1-mediated innate immunity.

Functional genomic responses toÂ temperatureÂ variation in adultÂ Drosophila mojavensis

Project description:Investigation of whole genome transcription expression level changes in Drosophila mojavensis wild-type populations (1 Punta Onah: PO, 2 Organ Pipe National Monument: OPNM, 3 Punta Prieta:PP, and 4 San Quintin: SQ). The experiment was designed to investigate functional genomic responses to temperature variation (15, 25, and 35 Â°C) in adult Drosophila mojavensis wild populations. For each treatment 1-5 replicates were used (R1, R2, R3, R4 & R5). SO and BC represents Sonora deserts and Baja California region respectively. A total of 97 hybridizations were performed in this entire experiment. We used 135K 12-plex NimbleGen arrays. Total RNA was recovered from each sample listed below. The experimental design consisted a total of four populations (Punta Onah:PO; Organ Pipe National Manument:OPNM, Punta Prieta:PP and San Quintin:SQ), two host diets (Agria:AG and Organ pipe:OP) and three temperature treatments (15, 25 and 35 Â°C). Each chip measures the expression level of 14528 transcripts. One to 5 replicates were used for each type (R1, R2, R3, R4 and R5). Fly source details are as follows: Punta Onah 2007:PO07; Organ Pipe National Monument 2008:OPNM08; Punta Prieta 2008:PP08; San Quintin 2008:SQ08.
