Ricin Trafficking in Cells [PDF]

Toxins, 2015
The heterodimeric plant toxin ricin binds exposed galactosyls at the cell surface of target mammalian cells, and, following endocytosis, is transported in vesicular carriers to the endoplasmic reticulum (ER). Subsequently, the cell-binding B chain (RTB) and the catalytic A chain (RTA) are separated reductively, RTA embeds in the ER membrane and then ...

Degeneration and impaired regeneration of gray matter oligodendrocytes in amyotrophic lateral sclerosis. [PDF]

, 2013
Oligodendrocytes associate with axons to establish myelin and provide metabolic support to neurons. In the spinal cord of amyotrophic lateral sclerosis (ALS) mice, oligodendrocytes downregulate transporters that transfer glycolytic substrates to neurons ...

Detection of Ricin Contamination in Ground Beef by Electrochemiluminescence Immunosorbent Assay

Toxins, 2011
Ricin is a highly toxic protein present in the seeds of Ricinus communis (castor), grown principally as a source of high quality industrial lubricant and as an ornamental.

Crystal Structure of the Cysteine-Rich Domain of Mannose Receptor Complexed with a Sulfated Carbohydrate Ligand [PDF]

, 2000
The macrophage and epithelial cell mannose receptor (MR) binds carbohydrates on foreign and host molecules. Two portions of MR recognize carbohydrates: tandemly arranged C-type lectin domains facilitate carbohydrate-dependent macrophage uptake of ...

Green Fuel Combustion Synthesis of CeO2 and Ag/CeO2 Nanoparticles for Photocatalytic and Antibacterial Applications

Asia-Pacific Journal of Chemical Engineering, EarlyView.
ABSTRACT Silver‐doped cerium oxide nanoparticles (Ag/CeO2 NPs) were synthesized using Ricinus communis seed extract as a bio‐derived fuel in a solution combustion method. The combustion reaction, carried out at 450°C with AgNO3 and (NH4)2[Ce (NO3)6] as metal precursors, produced CeO2 and Ag/CeO2 NPs.

Safety Assessment and Hypoglycemic Effect of Moringa oleifera Lam. Seed Lectin (WSMoL) in Alloxan‐Induced Diabetic Mice

Journal of Applied Toxicology, EarlyView.
ABSTRACT Moringa oleifera Lam. seeds contain WSMoL, a lectin previously studied for toxicity and pharmacological effects. In this study, we investigated WSMoL (10, 25, or 50 mg/kg i.p.) for acute and 14‐day repeated‐dose toxicity, as well as genotoxicity, in Swiss mice.

Characterization of MicroRNA and Gene Expression Profiles Following Ricin Intoxication

Toxins, 2019
Ricin, derived from the castor bean plant, is a highly potent toxin, classified as a potential bioterror agent. Current methods for early detection of ricin poisoning are limited in selectivity. MicroRNAs (miRNAs), which are naturally occurring, negative

Special issue: Ribosome-inactivating proteins : commemorative issue in honor of Professor Fiorenzo Stirpe [PDF]

, 2017
The family of ribosome-inactivating proteins (RIPs) groups all enzymes (EC.3.2.2.22) with a so-called RIP domain which comprises N-glycosidase activity and enables these proteins to catalytically inactivate ribosomes.[...

Edulitin 2, a Ribotoxin‐Like Protein From Boletus edulis That Triggers Apoptosis in Colon Cancer Cells While Preserving the Integrity of the Intestinal Microbiota

eFood, Volume 7, Issue 3, June 2026.
Edulitin 2 is a ribotoxin‐like protein exhibiting a potent antiproliferative activity towards Caco‐2 and HT29 cells by programmed cell death. However, edulitin 2 does not affect gut microbiota growth, despite damaging fungal ribosomes. ABSTRACT Porcini (Boletus edulis Bull.) are a reservoir of pharmacological biomolecules with health‐promoting ...

Hydroxyl radical footprinting modification reveals an intradomain communication pathway in EFL1 disrupted by a Shwachman‐Diamond syndrome‐associated mutation

Protein Science, Volume 35, Issue 4, April 2026.
Abstract Shwachman‐Diamond syndrome (SDS) is a rare genetic disorder characterized by pancreatic insufficiency and neutropenia. While most cases are linked to mutations in the SBDS gene, some involve mutations in the GTPase EFL1. This protein works with SBDS to release the anti‐association factor eIF6 from the 60S ribosomal subunit during ribosome ...
