Arginine deiminase system and bacterial adaptation to acid environments [PDF]

Applied and Environmental Microbiology, 1987
The arginine deiminase system in a variety of streptococci and in Pseudomonas aeruginosa was found to be unusually acid tolerant in that arginolysis occurred at pH values well below the minima for growth and glycolysis. The acid tolerance of the system allowed bacteria to survive potentially lethal acidification through production of ammonia to raise ...

Antibiotic‐mediated immune modulation in periodontitis

Periodontology 2000, EarlyView.
Abstract Periodontitis is a chronic inflammatory disease affecting the supporting structures of the teeth. Although initiated by dysbiotic microbial communities, its progression is largely driven by the host's uncontrolled inflammatory response. While antibiotics have conventionally been employed in periodontitis therapy for their antimicrobial ...

Sequence analysis and expression of the arginine‐deiminase and carbamate‐kinase genes of Pseudomonas aeruginosa

, 1989
The arcABC operon of Pseudomonas aeruginosa encodes arginine deiminase, catabolic ornithine carbamolytransferase and carbamate kinase, respectively. We have determined the nucleotide sequences of the arcA and arcC genes.

Intracellular arginine-dependent translation sensor reveals the dynamics of arginine starvation response and resistance in ASS1-negative cells

Cancer & Metabolism, 2021
Background Many cancers silence the metabolic enzyme argininosuccinate synthetase 1 (ASS1), the rate-limiting enzyme for arginine biosynthesis within the urea cycle. Consequently, ASS1-negative cells are susceptible to depletion of extracellular arginine

Photochemical Control of Protein Arginine Deiminase (PAD) Activity [PDF]

ACS Chemical Biology, 2018
Protein arginine deiminases (PADs) play an important role in the pathogenesis of various diseases, including rheumatoid arthritis, multiple sclerosis, lupus, ulcerative colitis, and breast cancer. Therefore, the development of PAD inhibitors has drawn significant research interest in recent years.

Ischemia–Reperfusion Injury: Molecular Mechanisms and Therapeutic Interventions

MedComm, Volume 7, Issue 7, July 2026.
Multiorgan ischemia–reperfusion injury begins with ischemia‐induced ATP depletion and ionic imbalance, followed by reperfusion‐triggered mitochondrial ROS/RNS bursts, regulated cell death, and DAMP release. Sterile inflammation converges on endothelial–immune–coagulation crosstalk, where NETs drive immunothrombosis, no‐reflow, and remote organ injury ...

Intratumoral Microbiota in Tumor: Current Understandings and Future Perspectives

MedComm, Volume 7, Issue 7, July 2026.
Intratumoral bacteria are emerging as active regulators of cancer evolution rather than bystanders. This review outlines how tumor‐resident microbes drive tumor initiation and growth by inducing genomic instability, epigenetic reprogramming, oncogenic signaling, and chronic inflammation, while promoting metastatic spread via invasion, angiogenesis ...

Turning on and turning off the arginine deiminase system in oral streptococci

, 1998
The arginine deiminase system in oral streptococci is highly regulated. It requires induction and is repressed by catabolites such as glucose or by aeration.

Pegargiminase Suppresses the Fanconi Anemia Pathway and Promotes Melphalan‐Induced DNA Double‐Strand Breaks in Uveal Melanoma

Pigment Cell &Melanoma Research, Volume 39, Issue 4, July 2026.
ADI‐PEG20 enhances melphalan‐induced DNA DSBs in UM cells. We describe potentiation of DNA DSBs in UM cell lines upon treatment with ADI‐PEG20 and melphalan (92.1 cells with STRIDE by intoDNA). ADI‐PEG20 suppresses multiple members of the FA pathway—a known resistance mechanism for melphalan—providing a rationale for exploring this drug combination in ...

DNA From Neutrophil Extracellular Traps Restricts Group 3 Innate Lymphoid Cells Function in Intestinal Epithelial Repair via CCDC25

The FASEB Journal, Volume 40, Issue 12, 30 June 2026.
DNA from neutrophil extracellular traps (NET‐DNA) restricts the function of IL‐22‐dependent ILC3s in intestinal defense through coiled‐coil domain containing protein 25 (CCDC25), which hinders the repair of intestinal epithelial cells and promotes the progression of UC.
