One-step purification and characterization of alginate lyase from a clinical Pseudomonas aeruginosa with destructive activity on bacterial biofilm [PDF]

open access: yesIranian Journal of Basic Medical Sciences, 2017
Objective(s): Pseudomonas aeruginosais a Gram-negative and aerobic rod bacterium that displays mucoid and non-mucoid phenotype. Mucoid strains secrete alginate, which is the main agent of biofilms in chronic P. aeruginosa infections, show high resistance

Evidence That Cytochrome \u3cem\u3eb\u3csub\u3e5\u3c/sub\u3e\u3c/em\u3e Acts as a Redox Donor in CYP17A1 Mediated Androgen Synthesis [PDF]

open access: yes, 2016
Cytochrome P450 17A1 (CYP17A1) is an important drug target for castration resistant prostate cancer. It is a bi-functional enzyme, catalyzing production of glucocorticoid precursors by hydroxylation of pregnene-nucleus, and androgen biosynthesis by a ...

The "backdoor pathway" of androgen synthesis in human male sexual development. [PDF]

open access: yes, 2019
Mammalian sex determination (male versus female) is largely controlled by genes, whereas sex differentiation (development of reproductive structures) is largely controlled by hormones. Work in the 20th century indicated that female external anatomy was a

Cloning, Expression, and Characterization of a New PL25 Family Ulvan Lyase from Marine Bacterium Alteromonas sp. A321

open access: yesMarine Drugs, 2019
Ulvan lyases can degrade ulvan to oligosaccharides with potent biological activity. A new ulvan lyase gene, ALT3695, was identified in Alteromonas sp. A321. Soluble expression of ALT3695 was achieved in Escherichia coli BL21 (DE3).

Inhibition and Rescue of Hyperglycemia‐Induced Cellular Senescence by Mitochondrial Transfer from Enucleated Mesenchymal Stem Cell‐Derived Microvesicles for Chronic Wound Healing

open access: yesAdvanced Science, EarlyView.
This study develops enucleated MSC‐derived microvesicles (Mito@euMVs) to deliver functional mitochondria for optimizing wound repair. By efficiently encapsulating mitochondria, Mito@euMVs rejuvenate hyperglycemia‐induced senescent fibroblasts and HUVECs. Using PVA microneedle patches, the therapeutic efficacy of Mito@euMVs is validated in diabetic rats

Alginate Lyase from Indonesian Bacillus megaterium S245 Shows Activities Toward Polymannuronate and Polyguluronate

open access: yesSqualen, 2017
Screening of alginate lyase producing bacteria associated with seaweed Sargassum crassifolium was carried out, and isolate S245, identified as Bacillus megaterium S245 was found to produce high alginate lyase activity.

The TET3/GATA6 Axis Drives Lipid Metabolism and Therapeutic Vulnerabilities in Pancreatic Ductal Adenocarcinoma

open access: yesAdvanced Science, EarlyView.
The DNA demethylase TET3 drives lipid metabolic reprogramming in pancreatic ductal adenocarcinoma via a non‐catalytic mechanism. TET3 recruits histone deacetylases to repress GATA6, sustaining lipogenic enzyme expression and ferroptosis resistance.

Mitochondria‐Targeting Abasic Site‐Reactive Probe (mTAP) Enables the Manipulation of Mitochondrial DNA Levels

open access: yesAngewandte Chemie, EarlyView.
Mitochondria‐targeting water‐soluble probe mTAP exclusively reacts with mitochondrial abasic sites, enabling the manipulation of mitochondrial DNA levels under genotoxic stress. Abstract Mitochondrial DNA (mtDNA) encodes essential genes for mitochondrial and cellular functions and acts as a cell signaling molecule in innate immune and inflammatory ...

Isolation and identification of an alginate lyase-producing marine bacterium strain and its enzymological characteristics

open access: yes浙江大学学报. 农业与生命科学版, 2013
Alginate polysaccharide produced by marine brown algae or certain Gram-negative bacteria is a linear anionic binary copolymer of β-D-mannuronic acid (M) and α-L-guluronic acid (G) residues. Alginate lyase (EC 4.2.2.3; EC 4.2.2.11), also known as alginase
