Behind anticancer molecules: lactoferricin dimeric peptides with fast, selective, persistent and broad-spectrum cytotoxic effect [PDF]

open access: yesExploration of Drug Science
Aim: To identify peptides derived from bovine lactoferricin (LfcinB) as potential therapeutics for colon cancer treatment. We systematically modified dimeric peptides to enhance their selectivity against colon cancer cells and reduce toxicity.

Bubble Formation Control: Fabrication of Centimeter‐Sized Tissue‐Like Constructs by Catalase‐Coated Oxygen‐Releasing Hydrogel

open access: yesAdvanced Materials, EarlyView.
Oxygen‐releasing hydrogels are widely used to support cell survival in 3D cultures and to promote wound healing. However, incorporating catalase to convert H2O2 into O2 often generates additional oxygen bubbles, leading to material instability which rarely addressed.

Channeling of extramitochondrial ornithine to matrix ornithine transcarbamylase.

open access: yesJournal of Biological Chemistry, 1987
In the presence of citrulline synthesis, we made the following observations. External ornithine is channeled between its transporter and ornithine transcarbamylase; mitochondria preloaded with cold ornithine, then incubated with [3H]ornithine, produced citrulline of the same specific radioactivity as that of external ornithine, while matrix ornithine ...

Nanoporous Silica Embedded in Nanoporous Platinum: A Versatile Composite Coating for Implant‐Associated Drug Delivery From Neuronal Electrodes

open access: yesAdvanced Materials Technologies, EarlyView.
Nanoporous silica nanoparticles incorporated in nanoporous platinum offer the possibility for implant‐associated drug delivery from neuronal electrodes. ABSTRACT Sensorineural hearing loss, resulting from damage to the hair cells of the inner ear, profoundly impairs quality of life.

Fermentation in Pineapple Juice Significantly Enhances Ornithine and Citrulline Production in Lactococcus lactis MSC-3G Isolated from Sugarcane

open access: yesMicroorganisms, 2022
Lactic acid bacterial (LAB) fermentation of functional amino acids using fruit juices as a cultivation medium is not well-documented. In the present study, we successfully isolated a high ornithine- and citrulline-producing Lactococcus lactis strain ...

A Dual‐Phase Exosomal Nanotherapy Enhances Continual Efferocytosis by Coordinating Checkpoint Inhibition and Metabolic Reprogramming in Atherosclerosis

open access: yesAdvanced Science, EarlyView.
Here we developed Am@SExo, a dual‐functional engineered exosome that coordinates CD47–SIRPα checkpoint blockade with Arg1 mRNA–mediated metabolic reprogramming. Surface SIRPα promotes recognition of apoptotic cells and plaque targeting, while Arg1 expression enhances arginine–ornithine metabolism, Rac1 activation, and actin remodeling in macrophages ...

Dysregulation of the urea cycle – potential targets for treatment and diagnosis in prostate cancer

open access: yesExpert Reviews in Molecular Medicine
Background Prostate cancer (PCa) exhibits profound metabolic reprogramming, including dysregulation of the urea cycle (UC), an emerging driver of tumour growth, therapy resistance, and immune modulation.

Structure and Function of Ornithine Carbamoyltransferases [PDF]

open access: yesEuropean Journal of Biochemistry, 1977
The reaction catalyzed by ornithine carbamoyltransferase can participate in either the anabolism or the catabolism of arginine. The carbamoylation of ornithine, yielding citrulline, is involved in the biosynthetic sequences; the reverse reaction, the phosphorolysis of citrulline, is the second step of the arginine deiminase pathway.The ornithine ...

Vascularized Liver‐on‐a‐Microsphere Reveals Alanine‐Glucose Metabolism‐Driven Regulation of Liver Function and Injury

open access: yesAdvanced Science, EarlyView.
A vascularized liver‐on‐a‐microsphere system is developed to recreate lobule‐like cellular organization and endothelial barrier function within compartmentalized hydrogel particles. The platform enhances hepatic performance and reveals alanine‐glucose cycle activation linked to improved detoxification capacity, offering a high‐throughput microscale ...
