Analysis of N-Linked Glycans as Potential Biomarkers of Clinical Course in Human Prostate Cancer.

Prostate cancer is the most common cancer in men worldwide. Despite its prevalence, there is a critical knowledge gap in understanding factors driving disparities in survival among different cohorts of patients with prostate cancer. Identifying molecular features separating disparate populations is an important first step in prostate cancer research that could lead to fundamental hypotheses in prostate biology, predictive biomarker discovery, and personalized therapy.

Antibody-Mediated Enzyme Therapeutics and Applications in Glycogen Storage Diseases.

The use of antibodies as targeting molecules or cell-penetrating tools has emerged at the forefront of pharmaceutical research. Antibody-directed therapies in the form of antibody-drug conjugates, immune modulators, and antibody-directed enzyme prodrugs have been most extensively utilized as hematological, rheumatological, and oncological therapies, but recent developments are identifying additional applications of antibody-mediated delivery systems. A novel application of this technology is for the treatment of glycogen storage disorders (GSDs) via an antibody-enzyme fusion (AEF) platform to penetrate cells and deliver an enzyme to the cytoplasm, nucleus, and/or other organelles.

Central Nervous System Delivery and Biodistribution Analysis of an Antibody-Enzyme Fusion for the Treatment of Lafora Disease.

Lafora disease (LD) is a fatal juvenile epilepsy characterized by the accumulation of aberrant glucan aggregates called Lafora bodies (LBs). Delivery of protein-based therapeutics to the central nervous system (CNS) for the clearance of LBs remains a unique challenge in the field. Recently, a humanized antigen-binding fragment (hFab) derived from a murine systemic lupus erythematosus DNA autoantibody (3E10) has been shown to mediate cell penetration and proposed as a broadly applicable carrier to mediate cellular targeting and uptake.

Mitochondrial Metabolism in Major Neurological Diseases.

Mitochondria are bilayer sub-cellular organelles that are an integral part of normal cellular physiology. They are responsible for producing the majority of a cell's ATP, thus supplying energy for a variety of key cellular processes, especially in the brain. Although energy production is a key aspect of mitochondrial metabolism, its role extends far beyond energy production to cell signaling and epigenetic regulation⁻functions that contribute to cellular proliferation, differentiation, apoptosis, migration, and autophagy.

Microdose Lithium NP03 Diminishes Pre-Plaque Oxidative Damage and Neuroinflammation in a Rat Model of Alzheimer's-like Amyloidosis.

Background: Microdose lithium is protective against Alzheimer's disease (AD), although the precise mechanisms through which its protective effects are conferred remain unclear.

Objective: To further examine the effects during the earliest stages of Aβ pathology, we evaluated whether NP03, a microdose lithium formulation, modulates Aβ-mediated oxidative damage and neuroinflammation when applied to a rat transgenic model of AD-like amyloidosis overexpressing amyloid precursor protein (APP).

Method: McGill-R-Thy1-APP transgenic rats and wild-type littermates were treated with NP03 or vehicle formulation for 8 weeks beginning at 3 months of age - a phase preceding Aβ plaque deposition in the transgenic rats.
