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. …

Explorative studies to understand if aldehyde dehydrogenase (ALDH) expression in colon cancer can be exploited as a target for therapeutic intervention. Expression profiling of ALDH7A1 in colorectal cancer
… to treat with current treatment options. Aldehyde dehydrogenases (ALDHs) are enzymes that play key roles in protecting cells against aldehyde-generated toxicity. Specific isoforms are also known to contribute to disease development. Emerging evidence suggests that specific ALDH isoforms …

Enzymology of butanol formation in Clostridium Beijerinckii
… did not increase simultaneously. 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 …

Comparison of Redox-Active and Conjugative Enzymes With and Without Efflux Transporters and Their Comparative Effectiveness in Protection Against Cellular Toxicity of 4-Hydroxy-2-Nonenal (HNE), an Aldehyde Lipid Peroxidation Production
… (HNE) is one of the most reactive aldehydes produced during lipid peroxidation (LPO) and has been demonstrated to have cytotoxic and genotoxic effects. Several oxidoreductases (ORs) have been reported to detoxify HNE including aldehyde dehydrogenase (ALDH) and aldo-keto reductases …

Mechanisms Underlying Alcohol-Mediated Cellular Injury In Esophageal Keratinocytes
… risk factor for developing ESCC. Acetaldehyde, a by-product of alcohol metabolism is a potent human carcinogen. Furthermore, single nucleotide polymorphisms (SNPs) in the alcohol metabolizing enzyme Aldehyde dehydrogenase (ALDH)-2 is strongly associated with ESCC. However, there is …

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, …

Targeting Aldehyde Dehydrogenases in NF2-null Meningioma and Schwannoma
… caused by NF2 loss, drives 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 …

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
… They are hypothesized 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 …

Acyloxy Nitroso Compounds as HNO Donors and Their Reactions with Thiol and Heme Containing Proteins
Nitroxyl (HNO), a nitrogen monoxide with distinct chemistry and biology, has gained interest as a potential treatment of congestive heart failure through the ability of the HNO donor, Angeli's salt (AS), to evoke positive inotropic effects in canine cardiac muscle. The release of nitrite during …

Investigation of the anti-breast cancer efficacy and mechanisms of disulfiram
… by DS/Cu. The common stem cell markers such as aldehyde dehydrogenase (ALDH) and CD24-/CD44+ as well as Nanog, Sox2, and Oct4 were also suppressed. In PAC resistant cell line, DS abolished CSC characters and completely reversed PAC resistance. Lipo-DS blocked NFκB activation and specifically …

Investigation of the anticancer activity and molecular mechanisms of Disulfiram in Glioblastoma Multiforme
… that hypoxia inducible factors (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 …
