Mechanism of cystathionine-β-synthase inhibition by disulfiram : The role of bis(N,N-diethyldithiocarbamate)-copper(II)

Zuhra, Karim ; Panagaki, Theodora ; B.Randi, Elisa ; Augsburger, Fiona ; Blondel, Marc ; Friocourt, Gaelle ; Herault, Yann ; Szabo, Csaba

Background: Hydrogen sulfide (H2S) is an endogenous mammalian gasotransmitter. Cystathionine β-synthase (CBS), cystathionine γ-lyase (CSE) and 3- mercaptopyruvate sulfurtransferase (3-MST) are the principal enzymes responsible for its biogenesis. A recent yeast screen suggested that disulfiram (a well-known inhibitor of aldehyde dehydrogenase and a clinically used drug in the treatment of...

Cystathionine-β-synthase: molecular regulation and pharmacological inhibition

Zuhra, Karim ; Augsburger, Fiona ; Majtan, Tomas ; Szabo, Csaba

In: Biomolecules, 2020, vol. 10, no. 5, p. 697

Cystathionine-β-synthase (CBS), the first (and rate-limiting) enzyme in the transsulfuration pathway, is an important mammalian enzyme in health and disease. Its biochemical functions under physiological conditions include the metabolism of homocysteine (a cytotoxic molecule and cardiovascular risk factor) and the generation of hydrogen sulfide (H2S), a gaseous biological mediator with...

Role of 3-mercaptopyruvate sulfurtransferase in the regulation of proliferation, migration, and bioenergetics in murine colon cancer cells

Augsburger, Fiona ; Randi, Elisa B. ; Jendly, Mathieu ; Ascencao, Kelly ; Nahzli Dilek ; Szabo, Csaba

In: Biomolecules, 2020, vol. 10, no. 3, p. 447

3-mercaptopyruvate sulfurtransferase (3-MST) has emerged as one of the significant sources of biologically active sulfur species in various mammalian cells. The current study was designed to investigate the functional role of 3- MST’s catalytic activity in the murine colon cancer cell line CT26. The novel pharmacological 3-MST inhibitor HMPSNE was used to assess cancer cell proliferation,...

Potential role of the 3-mercaptopyruvate sulfurtransferase (3-MST)—hydrogen sulfide (H2S) pathway in cancer cells

Augsburger, Fiona ; Szabo, Csaba

In: Pharmacological Research, 2020, vol. 154, p. 104083

Hydrogen sulfide (H2S), produced by various endogenous enzyme systems, serves various biological regulatory roles in mammalian cells in health and disease. Over recent years, a new concept emerged in the field of H2S biology, showing that various cancer cells upregulate their endogenous H2S production, and utilize this mediator in autocrine and paracrine manner to stimulate proliferation,...
