TranscriptomicsTranscription profiling of control and catalase-deficient Arabidopsis (Arabidopsis thaliana) plants
In plants, reactive oxygen species and, more particularly, hydrogen peroxide (H2O2) play a dual role as toxic by-products of normal cell metabolism and as regulatory molecules in stress perception and signal transduction. Peroxisomal catalases are an important sink for photorespiratory H2O2. Using A...

MetabolomicsDynamic change of IDO1 activity predicts survival in patients with unresectable stage III NSCLC and chemoradiotherapy

OBJECTIVES: High activity of Indoleamine 2,3-dioxygenase1 (IDO1) in lung cancer patients converts tryptophan (Trp), which is the essential amino acid for T cell metabolism, to kynurenine (Kyn) and consequently suppresses anti-tumor immune responses. We aimed to track the dynamics...

TranscriptomicsGenes Express in Catalase Overexpression MAECs
Study the global genes expression in mouse aorta endothelial cells (MAECs) overexpressing human catalase (hcatTg). The wild type and overexpressing human catalase (hcatTg) MAECs grown to 80% confluence in six-well plates were made quiescent in serum-free DMEM for 12 h and then cultured in 10% FBS DM...

TranscriptomicsC10ORF10/DEPP, a transcriptional target of FOXO3 regulates ROS-sensitivity by destabilizing peroxisomes in human neuroblastoma
FOXO transcription factors control cellular formation of reactive oxygen species (ROS), which critically contribute to cell survival and cell death in neuroblastoma. Here, we report that C10orf10, also named M-bM-^@M-^\Decidual Protein induced by Progesterone (DEPP)M-bM-^@M-^], is a direct transcrip...

ProteomicsIntradermal Delivery of Catalase via Extracellular Vesicles for Targeted Photoaging Therapy
We engineered a 313-cell line to produce EVs that were subsequently loaded with catalase (CAT), a key antioxidant enzyme. These CAT-loaded EVs (313EVs) exhibited high loading efficiency and maintained both vesicle integrity and enzymatic activity

TranscriptomicsPhotorespiratory stress in catalase deficient plants
Hydrogen peroxide (H2O2) can act as a signaling molecule that influences various aspects of plant growth and development, including stress signaling and cell death. To unravel the molecular mechanisms that regulate the response towards an impact of increased H2O2 levels in plant cells, we focused on...

TranscriptomicsExpression data provoked by H2O2 from plastid or peroxisomal origin
Reactive oxygen species (ROS) are key signalling molecules that regulate growth and development and coordinate responses to biotic and abiotic stresses. ROS homeostasis is controlled through a complex network of ROS production and scavenging enzymes. Recently, the first genes involved in ROS percept...

Antitoxins are becoming recognized as proteins that regulate more than their own synthesis; for example, we found previously that antitoxin MqsA represses the gene encoding the stationary phase sigma factor RpoS. Here, we investigated the physiological role of antitoxin DinJ of the DinJ/YafQ toxin/a...
