Aldehyde dehydrogenases (ALDH) expression in cancer tissues as potential pharmacological targets for therapeutic intervention. Probing ALDH expression and function in 2D- and 3D-cultured cancer cell lines
The aldehyde dehydrogenase (ALDH) superfamily is gaining momentum in regard to stem cell and cancer research. However, their regulation and expression in the cancer microenvironment is poorly understood. The aim of this work was to understand the role of selected ALDH isoforms (1A1, 1A2, 1A3, 1B1, …

Expression of Aldehyde dehydrogenase (ALDH) in the breast stem cell line D492 and relations to stem cell properties
Aldehyde dehydrogenases (ALDH) are enzymes expressed in both normal and cancer stem cells (CSC). CSCs are hypothesized to arise from normal stem cells and acquire a malignant phenotype through series of genetic mutations. Current therapies often fail to eradicate CSCs causing metastatic relapse. …

Targeting Aldehyde Dehydrogenases in NF2-null Meningioma and Schwannoma
… overexpression of aldehyde dehydrogenase 1A1 (ALDH1A1) in NF2-null schwannoma. High expression of ALDH1A1, and the related isoform ALDH1A3 have been identified as markers of cancer stem cell activity and have been correlated with poor prognosis and chemoresistance in several cancers. This …

IN-VITRO PK/PD PROFILING AND MODELING OF THE ANTI-SICKLING AGENTS, 5-HYDROXYMETHYL FURFURAL (5-HMF) AND NOVEL SYNTHETIC ALLOSTERIC EFFECTORS OF HEMOGLOBIN (AEH) IN HUMAN WHOLE BLOOD
… to be substrates for aldehyde dehydrogenase (ALDH) in the liver and red blood cells (RBC). Methods. Biopharmaceutical assessments were made for AEH, using calculated physicochemical properties. Their in-vitro hepatic metabolism (mediated by ALDH) was characterized using hepatic cytosol, and …

Towards the development of fluorescent probes targeting aldehyde dehydrogenase (ALDH) in cancer. Expression and epigenetic modulation of ALDH1A1, ALDH2 and ALDH3A1 in selected in vitro models.
… and measurement of high aldehyde dehydrogenase (ALDH) activity has been defined as a characteristic of stem cells (SCs). In this study, a library of novel small molecules (1,4-di-substituted acetalanthraquinones, AAQs), containing an acetal group as protected aldehyde functionality, was designed …

Investigating the expression and function of aldehyde dehydrogenases in prostate cancer. Probing the expression and function of ALDHs using chemical probes, drugs and siRNA
… and drug resistance. Aldehyde dehydrogenases (ALDHs) have been used in some tumour types as CSC markers. Their high expression and high functional activity found in CSCs is also associated with drug resistance. Emerging evidence suggests deregulation of certain ALDH isoforms have implications …

Enzymology of butanol formation in Clostridium Beijerinckii
… CoA-acylating aldehyde dehydrogenase (ALDH) was purified to near homogeneity. The ALDH showed a native M.. of 100,000, and a subunit Mr of 55,000. ALDH could use either NAD(H) or NADP(H) as the coenzyme. ALDH was oxygenlabile. The O₂-inactivated enzyme could be reactivated by incubating …

Humane Alkoholdehydrogenasen und Aldehyddehydrogenasen : Bedeutung für den Metabolismus von Methylpyrenderivaten und von 5-(Hydroxymethyl)-2-furfural
… (ADH) und Aldehyddehydrogenasen (ALDH) zur Carbonsäure könnte einen wichtigen Detoxifizierungsweg in Konkurrenz zur Aktivierung durch Sulfotransferasen (SULT) darstellen, was für 1-Hydroxymethylpyren in der Ratte bereits gezeigt wurde (Ma, L., Kuhlow, A. & Glatt, H. (2002). …

Investigation of the anticancer activity and molecular mechanisms of Disulfiram in Glioblastoma Multiforme
… (HIFs), NF-B and aldehyde dehydrogenase (ALDH) together orchestrate the stemness and chemoresistance in hypoxia induced CSCs. But the insights on the mechanisms still remain obscure. In this study we used an in vitro GBM CSC and hypoxia model along with NF-B-p65 and HIF transfected GBM …

The Role of Inflammatory Lipid Mediators on Colon Cancer Initiating Cells (CICs)
… this end, we identified the CICs on the basis of ALDH expression and evaluated their in vitro characteristics like colony formation, radio or chemoresistance and in vivo tumorigenic properties in the presence of LTD4 or PGE2. We showed that LTD4 and PGE2 enriched the ALDH+ cell population and …

The role of cancer stem cells in osteosarcoma
… The intracellular enzyme aldehyde dehydrogenase (ALDH) and tyrosine kinase receptor CD117 were found to be heterogeneously expressed amongst the cell lines. All cell lines when plated at low density could recapitulate the colony hierarchies based on variation in colony morphology (holoclones, …

Identification, kinetic and structural characterization of small molecule inhibitors of aldehyde dehydrogenase 3a1 (Aldh3a1) as an adjuvant therapy for reversing cancer chemo-resistance
ALDH isoenzymes are known to impact the sensitivity of certain neoplastic cells toward cyclophosphamides and its analogs. Despite its bone marrow toxicity, cyclophos-phamide is still used to treat various recalcitrant forms of cancer. When activated, cyclo-phosphamide forms aldophosphamide that can …
