Aiming to accommodate the unmet need for easily accessible biomarkers with a focus on biological differences between haematological diseases, the diagnostic value of plasma proteins in acute leukaemias and lymphomas was investigated. A multiplex proximity extension assay (PEA) was used to analyze 183 proteins in diagnostic plasma samples from 251 acute leukaemia and lymphoma patients and compared with samples from 60 healthy controls. Multivariate modelling using partial least square discriminant analysis revealed highly significant differences between distinct disease subgroups and controls. Read More

The liver is an essential regulator of energy metabolism, and its function can be disrupted by nutritional alterations. Since liver development continues during breastfeeding nutritional challenges during this period predispose patients to diseases throughout life. A maternal protein-restricted (PR) diet during lactation promotes reductions in the body weight, adiposity, and plasma glucose and insulin, leptin resistance and an increase in corticosterone and catecholamines in adult male rat offspring.

Matrix Biol 2022 Jun 29. Epub 2022 Jun 29.

Department of Dermatology and Cutaneous Biology, Thomas Jefferson University, Philadelphia, PA; The Joan and Joel Rosenbloom Research Center for Fibrotic Diseases, Thomas Jefferson University, Philadelphia, PA; Sidney Kimmel Cancer Center, Thomas Jefferson University, Philadelphia, PA. Electronic address:

Lack of type VII collagen (C7) disrupts cellular proteostasis yet the mechanism remains undescribed. By studying the relationship between C7 and the extracellular matrix (ECM)-associated proteins thrombospondin-1 (TSP1), type XII collagen (C12) and tissue transglutaminase (TGM2) in primary human dermal fibroblasts from multiple donors with or without the genetic disease recessive dystrophic epidermolysis bullosa (RDEB) (n=31), we demonstrate that secretion of each of these proteins is increased in the presence of C7. In dermal fibroblasts isolated from patients with RDEB, where C7 is absent or defective, association with the COPII outer coat protein SEC31 and ultimately secretion of each of these ECM-associated proteins is reduced and intracellular levels are increased.

The β adrenergic receptor agonist, formoterol, is an inducer of mitochondrial biogenesis and restorer of mitochondrial and kidney function in acute and chronic models of kidney injury. Unfortunately, systemic administration of formoterol has the potential for adverse cardiovascular effects, increased heart rate, and decreased blood pressure. To minimize these effects, we developed biodegradable and biocompatible polymeric nanoparticles containing formoterol that target the kidney, thereby decreasing the effective dose, and lessen cardiovascular effects while restoring kidney function after injury.

Bioorg Chem 2022 Jun 25;127:105983. Epub 2022 Jun 25.

Departamento de Química Orgánica, Facultad de Química, Universidad de Sevilla, Apartado 1203, E-41071 Sevilla, Spain.

Concerned by the urgent need to explore new approaches for the treatment of Alzheimer's disease, we herein describe the synthesis and evaluation of new multitarget molecules. In particular, we have focused our attention on modulating the activity of cholinesterases (AChE, BuChE) in order to restore the levels of the neurotransmitter acetylcholine, and of O-GlcNAcase (OGA), which is associated with hyperphosphorylation of tau protein, in turn related to the formation of neurofibrillary tangles in the brain. Specifically, we considered the possibility of using carbohydrate-fused 1,3-selenazolines, decorated with a 2-alkylamino or 2-alkoxy moieties. Read More

PARP1 and XRCC1 exhibit a reciprocal relationship in genotoxic stress response.

Cell Biol Toxicol 2022 Jul 1. Epub 2022 Jul 1.

Molecular Toxicology Group, Department of Biology, University of Konstanz, 78457, Constance, Germany.

PARP1 (aka ARTD1) acts as a prime sensor of cellular genotoxic stress response. PARP1 detects DNA strand breaks and subsequently catalyzes the formation of poly(ADP-ribose) (PAR), which leads to the recruitment of the scaffold protein XRCC1 during base excision and single strand break repair and the assembly of multi-protein complexes to promote DNA repair. Here, we reveal that the recruitment of either protein to sites of DNA damage is impeded in the absence of the other, indicating a strong reciprocal relationship between the two DNA repair factors during genotoxic stress response.
