Soil aminopeptidase activities under 145-year crop rotation and fertility practices in the North Central US

open access: yesGeoderma, 2023
Aminopeptidases catalyze the hydrolysis of peptides into constituent amino acids and are therefore a key step in nitrogen (N) depolymerization and downstream mineralization. Differences in carbon (C):N as well as sulfur (S) content of amino acids present

Phytochemical‐Based Strategies for Lung Cancer: Clinical Insights Into Pleiotropic Molecular Signaling and Therapeutic Roles

open access: yesPhytotherapy Research, EarlyView.
Lung cancer (LC) remains the leading cause of global cancer‐related death. Phytochemicals from medicinal plants are increasingly being considered as potential LC treatment agents due to their multi‐targeted action, safety, and accessibility. These have anticancer properties by regulating key molecular signaling pathways.

Metallo-aminopeptidase inhibitors

open access: yesBiochimie, 2010
Aminopeptidases are enzymes that selectively hydrolyze an amino acid residue from the N-terminus of proteins and peptides. They are important for the proper functioning of prokaryotic and eukaryotic cells, but very often are central players in the devastating human diseases like cancer, malaria and diabetes.

Activatable smart contrast agents for photoacoustic imaging

open access: yesSmart Molecules, EarlyView.
This review highlights recent advances in smart activatable photoacoustic imaging (PAI) contrast agents, which dynamically modulate their optical properties in response to external stimuli or microenvironmental cues. It discusses their molecular design, activation mechanisms, biomedical applications, and future prospects for clinically tailored use ...

Human cell line (HGC-27) derived from the metastatic lymph node of gastric cancer [PDF]

open access: yes, 1976
A cell line (HGC-27) was established by culture of the metastatic lymph node from a gastric cancer patient diagnosed histologically as undifferentiated carcinoma.

Positioning of Melflufen in Heavily Pretreated RRMM Patients: Real‐World Evidence in a Rapidly Evolving Therapeutic Landscape

open access: yesEuropean Journal of Haematology, EarlyView.
ABSTRACT Modern therapies have clearly marked the history of multiple myeloma (MM), leading to undisputed advantages in terms of sustained responses and prolonged survival, while progressively improving patients' quality of life. Nonetheless, disease recurrence and resistance to available therapies underscore the importance of identifying additional ...

Mechanisms of HIV Protein Degradation into Epitopes: Implications for Vaccine Design

open access: yesViruses, 2014
The degradation of HIV-derived proteins into epitopes displayed by MHC-I or MHC-II are the first events leading to the priming of HIV-specific immune responses and to the recognition of infected cells.

Structurally Distinct Active Sites in the Copper(II)-Substituted Aminopeptidases from \u3cem\u3eAeromonas proteolytica\u3c/em\u3e and \u3cem\u3eEscherichia coli\u3c/em\u3e [PDF]

open access: yes, 2002
The aminopeptidase from Aeromonas proteolytica (AAP) was titrated with copper, which bound sequentially at two distinct sites. Both the mono- and disubstituted forms of AAP exhibited catalytic hyperactivity relative to the native dizinc enzyme ...

The impact of accumulating immune adaptation in circulating strains of HIV‐1

open access: yesHIV Medicine, EarlyView.
Abstract Background Mutations in human immunodeficiency virus type 1 (HIV‐1) enable the virus to evade recognition and killing by human leucocyte antigen (HLA)‐restricted T cells. These viral adaptations are specific to the HLA type of individuals and are therefore evident as HLA allele‐HIV sequence associations at the population level. Most studies of

Type II Secretion-Dependent Aminopeptidase LapA and Acyltransferase PlaC Are Redundant for Nutrient Acquisition during Legionella pneumophila Intracellular Infection of Amoebas

open access: yesmBio, 2018
Legionella pneumophila genes encoding LapA, LapB, and PlaC were identified as the most highly upregulated type II secretion (T2S) genes during infection of Acanthamoeba castellanii, although these genes had been considered dispensable on the basis of the
