Medication-related osteonecrosis of the jaw (MRONJ) is a rare but serious adverse drug reaction. Our previous whole-exome sequencing study found SIRT1 intronic region SNP rs7896005 to be associated with MRONJ in cancer patients treated with intravenous (IV) bisphosphonates (BPs). This study aimed to identify causal variants for this association. In...

Antibiotic-resistant bacteria and surface-attached biofilms continue to play a significant role in human health and disease. Innovative strategies are needed to identify new therapeutic leads to tackle infections of drug-resistant and tolerant bacteria. We synthesized a focused library of 14 new halogenated quinolines to investigate the impact of C...

Bacterial biofilms, comprised of persister cells housed within extracellular biomolecular matrices, are a major contributor to chronic and recurring infections that are antibiotic tolerant. Biofilms are present in ~80% of microbial infections and are implicated in >500,000 deaths from infections per year. There are currently no clinically available...

Paenibacillus sp. JDR-2 (Pjdr2) has been studied as a model for development of bacterial biocatalysts for efficient processing of xylans, methylglucuronoxylan, and methylglucuronoarabinoxylan, the predominant hemicellulosic polysaccharides found in dicots and monocots, respectively. Pjdr2 produces a cell-associated GH10 endoxylanase (Xyn10A1) that...
Article
Full-text available
Methylglucuronoxylans (MeGXn) and methylglucuronoarabinoxylans (MeGAXn) respectively comprise most of the hemicellulose fractions in dicots and monocots and, next to cellulose, are the major resources for the production of fuels and chemicals from lignocellulosics. With either MeGXn or MeGAXn as a substrate, Bacillus subtilis 168 accumulates acidic...

Paenibacillus sp. JDR-2 (Pjdr2) secretes a multi-modular cell-associated GH10 endoxylanase (XynA10A1) which catalyzes depolymerization of methylglucuronoxylan (MeGXn) and rapidly assimilates the products of depolymerization. Efficient utilization of MeGXn has been postulated to result from the coupling of the processes of exocellular depolymerizati...

In this study, on evaluating the physiological function and mechanism of putrescine, we found that putrescine supplementation (1 mM) increases transcription of the putrescine aminotransferase gene, ygjG. Putrescine-dependent expression was confirmed by measuring β-galactosidase activity and with reverse transcription-polymerase chain reaction. To u...
Article
A systematic investigation into lowered degradation rates of glyphosate in metal-contaminated soils was performed by measuring mineralization of [(14)C]glyphosate to (14)CO(2) in two mineral soils that had been spiked with Cu and/or Zn at various loadings. Cumulative (14)CO(2) release was estimated to be approximately 6% or less of the amount of [(...

The effects of two natural poly. mines (putrescine and spermidine) on the synthesis of ArcA, a response regulator of the Arc two-component signal transduction system, were studied using an E. coli mutant deficient in polyamine biosynthesis. Endogenous polyamine deficiency of the mutant resulted in marked reduction in the ArcA level determined by We...
