Role of aldehyde dehydrogenase on the metabolic regulation in Clostridium ljungdahlii fermentation

Project description:Clostridium ljungdahlii not only utilizes CO, but also H2 as energy source during autotrophic growth. And C. ljungdahlii also grows in fructose fermentation. In theory, fructose is a more energetically favourable energy source than syngas in the fermentation of C. ljungdahlii. However, C. ljungdahlii grows insufficiently in fructose and produces less acetate and ethanol, compared to syngas fermentation. In this study, C. ljungdahlii wild type and mutants were fermented on fructose. C. ljungdahlii produced less ethanol than the ΔadhE1 mutant and consumed less fructose. The ΔadhE1+2 mutant cannot grow in the syngas fermentation and produced less ethanol among the three strains. The results showed that aldehyde dehydrogenase inactivation led to efficient metabolism in C. ljungdahlii and the bifunctional aldehyde/alcohol dehydrogenases inactivation led to decrease metabolism. Thus, comparative transcriptomes among cells grown on fructose of three strains were performed to investigate gene expression profiles based on three biological replicates.

2 Role of aldehyde dehydrogenase on the metabolic regulation in Clostridium ljungdahlii fermentation

Project description:Clostridium ljungdahlii can utilize CO as energy source during autotrophic growth. C. ljungdahlii grows sufficiently in CO and produces ethanol as the main product. In this study, C. ljungdahlii wild type and mutant were fermented on CO. C. ljungdahlii produced more ethanol than the ΔadhE1 mutant. The results showed that aldehyde dehydrogenase inactivation led to inefficient metabolism in C. ljungdahlii. Thus, comparative transcriptomes among cells grown on CO of WT and ΔadhE1 mutant were performed to investigate gene expression profiles based on three biological replicates.

Energy conservation and carbon flux arrangement in the fermentation of Clostridium ljungdahlii with CO or CO2/H2

Project description:Clostridium ljungdahlii not only utilizes CO, but also H2 as energy source during autotrophic growth. In theory, CO is a more energetically and thermodynamically favourable energy source than H2 in the gas fermentation of C. ljungdahlii. However, how C. ljungdahlii conserves energy for growth and ethanol/acetate formation grown on CO or CO2/H2 is not in great detail. In this study, C. ljungdahlii was fermented on CO and CO2/ H2 at pH 6.0 with 0.1 MPa gas pressure. C. ljungdahlii produced 27 g/L acetate, 9 g/L ethanol, 8 g/L 2,3-butanediol and traces of lactate in the presence of CO as energy source, while it produced 25.8  0.1 g/L acetate, 1.8  0.1 g/L ethanol, 0.7  0.01g/L 2,3-butanediol and trances of lactate in the same fermentation condition using H2 as energy source. Therefore, comparative transcriptomes between cells grown on CO and cells grown on H2/CO2 were performed to investigate gene expression profiles based on three biological replicates.

Gene expression data from endometrial cancer patient-derived cells (PDCs) treated with aldehyde dehydrogenase inhibitor

Project description:Three lines of PDCs (EnC-A, EnC-B, and EnC-C) were established from endometrial cancer specimens. Aldehyde dehydrogenase (ALDH) inhibition repressed the cell growth with altered gene expression.

Analysis of tumor cell plasticity in endometrioid carcinoma using cancer stem cell marker aldehyde dehydrogenase (ALDH)

Project description:To investigate the tumor cell plasticity using aldehyde dehydrogenase (ALDH) 1A1 activity, we established two distinct HEC-1B sublines, in which ALDH1A1-high population accelerated such transition and ALDH1A1-high population did not show such acceleration.

RNA-Seq of Clostridium ljungdahlii with CO as the sources of carbon and energy in exponetial phase against stationary phase

Project description:More than 5 g/L ethanol was detected at 84 h in the late-exponential phase with 0.1 MPa at pH 6.0 in the batch fermentation of C. ljungdahlii grown autotrophically. Interestingly, ethanol started to be reassimilated in the stationary phase. In order to understand the metabolic flux of ethanol, comparative transcriptome between exponential and stationary phases were performed.

Nuclear receptor NHR-49 promotes peroxisome proliferation to compensate for aldehyde dehydrogenase deficiency in C. elegans

Project description:The intracellular level of fatty aldehydes is tightly regulated to minimize the formation of toxic aldehyde adducts of cellular components. Accordingly, deficiency of a fatty aldehyde dehydrogenase FALDH causes the neurologic disorder Sjögren-Larsson syndrome (SLS) in humans. However, cellular responses to unresolved, elevated fatty aldehyde levels are poorly understood. Based on lipidomic and imaging analysis, we report that the loss of endoplasmic reticulum-, mitochondria- and peroxisomes-associated ALH-4, the C. elegans FALDH ortholog, increases fatty aldehyde levels and reduces fat storage. ALH-4 deficiency in the intestine, cell-nonautonomously induces NHR-49/NHR-79-dependent hypodermal peroxisome proliferation. This is accompanied by the upregulation of catalases and fatty acid catabolic enzymes, as indicated by RNA sequencing. Such a response is required to counteract ALH-4 deficiency since alh-4; nhr-49 double mutant animals are not viable. Our work reveals unexpected inter-tissue communication of fatty aldehyde levels, and suggests pharmacological modulation of peroxisome proliferation as a therapeutic strategy for SLS.
