Fibronectin sensitizes activation of contractility, YAP, and NF-κB in nucleus pulposus cells.

Intervertebral disc degeneration involves the breakdown of the discs of the spine due to genetics, aging, or faulty mechanical loading. As part of the progression of the disease, nucleus pulposus cells lose their phenotypic characteristics, inducing inflammation and extracellular matrix (ECM) alterations that result in a loss of disc mechanical homeostasis. Fibronectin is one ECM molecule that has been shown to be upregulated in disc degeneration and plays an important role in the progression of a wide variety of fibrotic diseases.

Anchors: A way for FtsZ filaments to stay membrane bound.

Most bacteria use the tubulin homolog FtsZ to organize their cell division. FtsZ polymers initially assemble into mobile complexes that circle around a ring-like structure at the cell midpoint, followed by the recruitment of other proteins that will constrict the cytoplasmic membrane and synthesize septal peptidoglycan to divide the cell. Despite the need for FtsZ polymers to associate with the membrane, FtsZ lacks intrinsic membrane binding ability.

Novel Antimicrobial Peptide SAAP Mutant as a Better Adjuvant to Sulbactam-Based Treatments Against Clinical Strains of XDR Acinetobacter baumannii.

The production of extended spectrum β-lactamases (ESBLs) in extensively drug-resistant (XDR) strains of Acinetobacter baumannii has created havoc amongst clinicians making the treatment procedure challenging. Carbapenem-resistant strains have displayed total ineffectiveness towards newer combinations of β-lactam-β-lactamase inhibitors (βL-βLI) in tertiary healthcare settings. Therefore, the present study was aimed to design potential β-lactamase antimicrobial peptide (AMP) inhibitors against ESBLs produced by the strains.

Elucidating the correlation between the number of TTTTGAT heptamer repeats and cholera toxin promoter activity in Vibrio cholerae O1 pandemic strains.

A complex virulence-regulatory cascade controls expression of the cholera toxin genes (ctxAB) in Vibrio cholerae, which eventually leads to the production and secretion of choleragen (CT), responsible for rice watery diarrhoea in infected individuals. The cholera toxin promoter (PctxAB) contains a series of heptad repeats (5'-TTTTGAT-3'), which has previously been shown to play a crucial role in transcriptional regulation of ctxAB by recruiting the transcriptional activators ToxT, ToxR and the nucleoid-associated protein H-NS along the ctx promoter. The number of these repeats differs not only between the two biotypes of V.

Role of the nucleotide excision repair pathway proteins (UvrB and UvrD2) in recycling UdgB, a base excision repair enzyme in Mycobacterium smegmatis.

Cross-talks between DNA repair pathways are emerging as a crucial strategy in the maintenance of the genomic integrity. A double-stranded (ds) DNA specific DNA glycosylase, UdgB is known to excise uracil, hypoxanthine and ethenocytosine. We earlier showed that Mycobacterium smegmatis (Msm) UdgB stays back on the AP-sites it generates in the DNA upon excision of the damaged bases.

Kinetic modeling and statistical optimization of submerged production of anti-Parkinson's prodrug -DOPA by .

-DOPA, a precursor of dopamine, is the drug of choice for Parkinson's disease, which persists due to decreased levels of dopamine in the brain. Present study emphasis the microbial production of -DOPA rather than the biotransformation of -DOPA by L-tyrosine. The production of -DOPA by bacterial isolates had gained more acceptance due to its more straightforward extraction and downstream processes.

In silico structure evaluation of BAG3 and elucidating its association with bacterial infections through protein-protein and host-pathogen interaction analysis.
