Abstract
Objective It's crucial to identify an easily detectable biomarker that is specific to radiation injury in order to effectively classify injured individuals in the early stage in large-scale nuclear accidents. Methods C57BL/6J mice were subjected to whole-body and partial-body γ irradiation, as well as whole-body X-ray irradiation to explore the response of serum sSelectin-L to radiation injury. Then, it was compared with its response to lipopolysaccharide-induced acute infection and doxorubicin-induced DNA damage to study the specificity of sSelectin-L response to radiation. Furthermore, it was further evaluated in serum samples from nasopharyngeal carcinoma patients before and after radiotherapy. Simulated rescue experiments using Amifostine or bone marrow transplantation were conducted in mice with acute radiation syndrome to determine the potential for establishing sSelectin-L as a prognostic marker. The levels of sSelectin-L were dynamically measured using the ELISA method. Results Selectin-L is mainly expressed in hematopoietic tissues and lymphatic tissues. Mouse sSelectin-L showed a dose-dependent decrease from 1 day after irradiation and exhibited a positive correlation with lymphocyte counts. Furthermore, the level of sSelectin-L reflected the degree of radiation injury in partial-body irradiation mice and in nasopharyngeal carcinoma patients. sSelectin-L was closely related to the total dose of γ or X ray. There was no significant change in the sSelectin-L levels in mice intraperitoneal injected with lipopolysaccharide or doxorubicin. The sSelectin-L was decreased slower and recovered faster than lymphocyte count in acute radiation syndrome mice treated with Amifostine or bone marrow transplantation. Conclusions Our study shows that sSelectin-L has the potential to be an early biomarker to classify injured individuals after radiation accidents, and to be a prognostic indicator of successful rescue of radiation victims.

J Vet Pharmacol Ther 2019; 42:732-737. [PMID: 31490576 DOI: 10.1111/jvp.12807] [Citation(s) in RCA: 5] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/17/2019] [Revised: 07/31/2019] [Accepted: 07/31/2019] [Indexed: 12/15/2022]
Abstract
The aim of the research was to investigate the anti-endotoxin and anti-inflammatory effects of Sinomenine, an agent commonly found in Chinese herbal medicines. Endotoxin (i.e., 1 mg lipopolysaccharide (LPS)/kg)) was administered via intraperitoneal (IP) injection to piglets in high-, middle-, and low-dose sinomenine groups. Piglets were then treated with 1, 5 or 10 mg/kg sinomenine, intramuscularly (i.m.), 3 hr after LPS. Vehicle was administered, as above, to drug control group piglets followed 3 hr later by 10 mg/kg sinomenine i.m.. LPS control group piglets were challenged with 1 mg/kg LPS IP, followed by vehicle i.m., and naïve control piglets were treated with normal saline IP, followed by normal saline i.m., as above. Temperatures were measured, and blood samples were collected from the precaval veins of piglets at 12, 24, and 48 hr post-LPS or vehicle injection. Clinical signs were recorded, and index levels were analyzed via ELISA. Sinomenine was found to reduce the incidence and severity of LPS-induced toxicities, including body temperature elevation, cell adhesion, and systemic inflammation. These data suggest that sinomenine may be effective for regulating inflammatory responses and has the potential for use as an anti-endotoxin therapy.

Abstract
OBJECTIVE Patients with systemic lupus erythematosus are genetically predisposed to enhanced production of the type-I interferon IFN-α and are also at elevated risk of developing atherosclerosis compared with healthy subjects. We aimed to test whether genetic predisposition to increased type-I IFN production affects risk of coronary artery disease. APPROACH AND RESULTS Using a list of 11 single nucleotide polymorphisms from the results of genome-wide association studies for systemic lupus erythematosus, which we hypothesised would be enriched in variants that regulate type-I IFN production, we identified a genetic risk score based on 3 single nucleotide polymorphisms (rs10516487, rs3131379 and rs7574865), which correlated significantly with production of IFN-α by human peripheral leukocytes stimulated with CpG-oligonucleotide (n=60, P=1.50 × 10(-5)). These single nucleotide polymorphisms explained 27.8% of variation in the CpG-oligonucleotide-induced IFN-α response and were also associated with Toll-like receptor-7/8- and Toll-like receptor-9-dependent IFN-α and IFN-β responses, but were not associated with inflammatory cytokine production in response to Toll-like receptor-4 stimulation or risk of coronary artery disease in 22,233 cases and 64,762 controls (odds ratio 1.00, 95% CI 0.98-1.02) using Mendelian randomization-based analyses. Coronary artery disease risk was also not associated with the full panel of 11 systemic lupus erythematosus single nucleotide polymorphisms or loci responsible for the monogenic type-I interferonopathies Aicardi-Goutières syndrome and Spondyloenchondrodysplasia with immune dysregulation. CONCLUSIONS The results argue against the potential utility of drugs targeting type-I IFN production for coronary artery disease. The use of genetic variants that modify leukocyte signaling pathways, rather than circulating biomarkers, as instruments in Mendelian randomization analyses may be useful for studies investigating causality of other candidate pathways of atherogenesis.
