Porphyromonas gingivalis GroEL accelerates abdominal aortic aneurysm formation by matrix metalloproteinase‐2 SUMOylation in vascular smooth muscle cells: A novel finding for the activation of MMP‐2

open access: yesMolecular Oral Microbiology, EarlyView.
Abstract Infection is a known cause of abdominal aortic aneurysm (AAA), and matrix metalloproteases‐2 (MMP‐2) secreted by vascular smooth muscle cells (SMCs) plays a key role in the structural disruption of the middle layer of the arteries during AAA progression.

GcrR in Streptococcus mutans Inhibits the Morphological Transition of Candida albicans Through Ras1–cAMP/PKA Pathway in the Cross‐Kingdom Biofilms

open access: yesMolecular Oral Microbiology, EarlyView.
ABSTRACT The dual‐species biofilms formed by Streptococcus mutans and Candida albicans exhibit enhanced cariogenic potential due to the production of extracellular polysaccharides (EPSs). The response regulator GcrR in S. mutans negatively regulates EPS synthesis, but its impact on dual‐species biofilms remains unclear.

AhBWR15, A Novel RLK Gene, Confers Resistance to Ralstonia solanacearum in Peanut

open access: yesPlant Biotechnology Journal, EarlyView.
ABSTRACT Bacterial wilt (BW), a severe soil‐borne disease caused by Ralstonia solanacearum, significantly impedes global peanut production. Despite its impact, the mechanisms underlying BW resistance in peanut remain unclear. Herein, we selected the highly resistant variety Nongdahua108 (H108) and the susceptible variety Nongdahua107 (H107) to develop ...

Adsorption of aspartic acid on kaolinite

Journal of Colloid and Interface Science, 2004
The interaction of aspartic acid with kaolinite was studied by potentiometric titrations and by adsorption measurements both at constant aspartate concentration (but varying pH) and at a constant pH of 5.5. The temperature was 25 degrees C, and the ionic medium 5 mM KNO3.

Oxovanadium(iv) complexes of salicyl-l-aspartic acid and salicylglycyl-l-aspartic acid

Dalton Transactions, 2005
The dipeptide and tripeptide analogues salicyl-L-aspartic acid (Sal-L-Asp) and salicylglycyl-L-aspartic acid (SalGly-L-Asp) were synthesized and their protonation and complex formation with V(IV)O2+ were studied in aqueous solution through the use of pH-potentiometry and spectroscopic (UV-Vis, CD and EPR) techniques. The phenolate terminus proved to be

Conjugation of aspartic acid with 4-bromophenylacetic acid, an auxin analogue of aspartic acid

Phytochemistry, 1987
Abstract Tobacco mesophyll protoplasts conjugate the auxins indoleacetic acid and naphthaleneacetic acid with aspartic acid very efficiently. This conjugation was found to be correlated with the toxicity of these molecules to protoplast-derived cells grown at low densities.

POLY(ASPARTIC ACID) HYDROGEL

Journal of Macromolecular Science, Part A, 1999
ABSTRACT Stimuli-responsive hydrogels have attracted much interest recently [1]. In this paper, we report a pH- and electrolyte-responsive hydrogel based on a crosslinked poly(aspartic acid). The lightly crosslinked, high molecular weight sodium polyas-partate impart extremely high water absorbency and can be used as a superabsorbent [2], It is derived
