  • The Identification of Human Aldo-Keto Reductase AKR7A2 As a Novel
    Li et al. Cellular & Molecular Biology Letters (2016) 21:25 Cellular & Molecular DOI 10.1186/s11658-016-0026-9 Biology Letters SHORTCOMMUNICATION Open Access The identification of human aldo-keto reductase AKR7A2 as a novel cytoglobin- binding partner Xin Li, Shanshan Zou, Zhen Li, Gaotai Cai, Bohong Chen, Ping Wang and Wenqi Dong* * Correspondence: [email protected] Abstract Department of Biopharmaceutics, School of Laboratory Medicine and Cytoglobin (CYGB), a member of the globin family, is thought to protect cells from Biotechnology, Southern Medical reactive oxygen and nitrogen species and deal with hypoxic conditions and University, 1838 North Guangzhou oxidative stress. However, its molecular mechanisms of action are not clearly Avenue, Guangzhou 510515, China understood. Through immunoprecipitation combined with a two-dimensional electrophoresis–mass spectrometry assay, we identified a CYGB interactor: aldo-keto reductase family 7 member A2 (AKR7A2). The interaction was further confirmed using yeast two-hybrid and co-immunoprecipitation assays. Our results show that AKR7A2 physically interacts with CYGB. Keywords: CYGB, AKR7A2, Protein-protein interactions, Yeast two-hybrid assay, Co-immunoprecipitation, 2-DE, Oxidative stress Introduction Cytoglobin (CYGB), which is a member of the globin family, was discovered more than a decade ago in a proteomic screen of fibrotic liver [1]. It was originally named STAP (stellate activating protein). Human CYGB is a 190-amino acid, 21-kDa protein [2], encoded by a single copy gene mapped at the 17q25.3 chromosomal segment [3]. It has a compact helical conformation, giving it the ability to bind to heme, which allows reversible binding of gaseous, diatomic molecules, including oxygen (O2), nitric oxide (NO) and carbon monoxide (CO), just like hemoglobin (Hb), myoglobin (Mb) and neuroglobin (Ngb) [4].

This work is licensed under the Creative Commons Attribution International License (CC BY). http://creativecommons.org/licenses/by/4.0/ Abstract Foxtail millet (Setaria italica L.) is a drought-tolerant millet crop of arid and semi-arid regions. Aldo-keto reductases (AKRs) are significant part of plant defence mechanism, having an ability to confer multiple stress tolerance. In this study, AKR1 gene expression was studied in roots and leaves of foxtail millet subjected to different regimes of PEG- and NaCl-stress for seven days. The quantita- tive Real-time PCR expression analysis in both root and leaves showed upregulation of AKR1 gene during PEG and salt stress. A close correlation exits between expression of AKR1 gene and the rate of lipid peroxidation along with the retardation of growth. Tissue-specific differences were found in the AKR1 gene expression to the stress intensities studied. The reduction in root and shoot growth under both stress conditions were dependent on stress severity. The level of lipid peroxidation as indicated by MDA formation was significantly increased in roots and leaves along with increased stress levels.

Translational Relevance Castration resistant prostate cancer (CRPC) is characterized by the emergence of a hypersensitive androgen signaling axis after orchiectomy or medical castration. The revival of androgen signaling is believed to be due to high intra-tumoral androgen synthesis, fueled by up-regulation of steroidogenic enzymes, including AKR1C3. Here, for the first time, using molecular and in vivo preclinical models, and human CRPC tissues, we demonstrate that the steroidogenic enzyme AKR1C3 also acts as a selective coactivator for androgen receptor to promote CRPC growth.

Vorsitzender: Univ.-Prof. Dr. Martin Hrabe de Angelis Prüfer der Dissertation: 1. apl. Prof.Dr. Jerzy Adamski 2. Univ.-Prof. Dr. Johannes Buchner Die Dissertation wurde am 09.05.2016 bei der Technischen Universität München eingereicht und durch die Fakultät für Wissenschaftszentrum Weihenstephan für Ernärung Landnutzung und Umwelt der Technischen Universität München am 25.11.2016 angenommen. Zusammenfassung Hydroxysteroiddehydrogenasen (HSDs) spielen eine bedeutende Rolle in Regulierung der Biosynthese von Steroidhormonen und gehören zur zwei großen Familien der Enzymen: short chain dehydogenases (SDR) und der aldo-keto reductases (AKR). Die Fehlregulierung einiger HSD-Aktivitäten führt zu verschiedenen schweren Störungen wie Alzheimer Syndrom oder hormonabhängigem Krebs. Deshalb stellen die HSDs schon seit vielen Jahren interessante Ziele für die der pharmazeutische Industrie für die Entwicklung neuer spezifischer Inhibitoren dar. Zwei der 17β-Hydroxysteroid dehydrogenasen, die 17β-Hydroxysteroiddehydrogenase Typ 3 (zur Familie der short chain dehydogenases (SDRs) gehörend) und die 17β-Hydroxysteroid Dehydrogenase Typ 5 (eine Aldo-Keto Reduktase (AKR)), katalysieren die Testosteron Biosynthese und ihre Überaktivität wird assoziiert mit einigen Krankheiten wie Prostatakrebs. Die Fortschritte in der Bioinformatik und Computer-basierten Methoden für Molekulare Modellierung ermöglichen Hochdurchsatz-Screening Methoden und erleichtern erheblich die systematische Entwicklung neuer enzym-spezifischer Liganden mit den gewünschten Eigenschaften, die später als Medikamente dienen könnten.

Here, we demonstrated that AKR1C1/C2 increased the metabolism of ethyl-3,4-dihydroxybenzoate (EDHB) in esophageal squamous cell carcinoma (ESCC) cells. Previous studies have shown that EDHB can effectively induce esophageal cancer cell autophagy and apoptosis, and the AKR1C family represents one set of highly expressed genes after EDHB treatment.

Our objective is to identify potential biomarkers to distinguish the biological effects of combustible tobacco products from those of non-combustible using oral cell lines. Normal human gingival epithelial cells (HGEC), non-metastatic (101A) and metastatic (101B) OSCC cell lines were exposed to different tobacco product preparations (TPPs) including cigarette smoke total particulate matter (TPM), whole-smoke conditioned media (WS-CM), smokeless tobacco extract in complete artificial saliva (STE), or nicotine (NIC) alone.
