MetabolomicsDecreasing peptide deformylase activity is a beneficial strategy for increasing formaldehyde resistance in Methylobacterium extorquens
Formaldehyde is a highly toxic metabolite that can cause extensive damage to DNA and proteins, and strategies to mitigate formaldehyde toxicity are poorly understood. Methylotrophic bacteria, such as Methylobacterium extorquens, thrive on one-carbon compounds as sole sources of carbon and energy. Th...

TranscriptomicsTranscription profiling of S. cerevisiae to investigate formaldehyde as source of free-energy during growth on glucose
Previously, it has been demonstrated that formate can be utilized by Saccharomyces cerevisiae as additional energy source using cells grown in a glucose-limited chemostat. Here, we investigated utilization of formaldehyde as co-substrate. Since endogenous formaldehyde dehydrogenase activities were i...

TranscriptomicsFormaldehyde-induced changes in microRNA signaling [Agilent]
MicroRNAs (miRNAs) are critical regulators of gene expression, yet much remains unknown regarding miRNA changes resulting from environmental exposures and whether they influence pathway signaling across various tissues and time. To gain knowledge on these novel topics, we set out to investigate in v...

TranscriptomicsFormaldehyde-induced changes in microRNA signaling [Affymetrix]
In addition to gaining knowledge on in vivo miRNA responses to formaldehyde, we set out to relate these miRNA responses to transcriptional profiles modified by formaldehyde. Rats were exposed by inhalation to either 0 or 2 ppm formaldehyde (6 hours/day) for 28 days. Genome-wide transcriptional profi...

TranscriptomicsGene expression microarray analysis of rat nasal tissue with time and dose following formaldehyde inhalation
Formaldehyde (FA), an endogenous cellular aldehyde, is a rat nasal carcinogen. In this study, concentration- and exposure-duration transitions in FA mode of action (MOA) were examined with pharmacokinetic (PK) modeling for tissue formaldehyde acetal (FAcetal) and glutathione (GSH) and with histopath...

TranscriptomicsThe global expression profile of Bacillus subtilis to the toxic carbonyls methylglyoxal (MG) and formaldehyde (FA)
Abstract of associated menuscript; Quinones and alpha,beta-unsaturated carbonyls are naturally occurring electrophiles that target cysteine residues via thiol-(S)-alkylation. We analyzed the global expression profile of Bacillus subtilis to the toxic carbonyls methylglyoxal (MG) and formaldehyde (FA...

TranscriptomicsAssessment of genotoxic effects and changes in gene expression in humans exposed to formaldehyde by inhalation under controlled conditions
41 volunteers (male non-smokers) were exposed to formaldehyde (FA) vapors for 4 h per day over a period of 5 working days under strictly controlled conditions. For each exposure day, different exposure concentrations were used in a random order ranging from 0 up to 0.7 ppm. At concentrations of 0.3 ...

ProteomicsFormaldehyde fixation helps preserve the proteome state during single-cell proteomics sample processing and analysis
Mass spectrometry-based single-cell proteomics (SCP) is gaining momentum but remains limited to a few laboratories due to the high costs and specialized expertise required. The ability to send samples to specialized core facilities would benefit non-specialist labs and popularize SCP for biological ...

ProteomicsFormaldehyde derivatization, a Side Reaction During Filter-Aided Sample Preparation
The filter-aided sample preparation (FASP) method has been commonly used for proteomic sample preparation due to its high efficiency and convenience. Herein, we report an overlooked side reaction during FASP method, resulting in a mass increment of 12 Da. We confirmed that the side reaction is cause...
