Gene expression correlates with disability and pain intensity in patients with chronic low back pain and Modic changes in a sex-specific manner

Project description:Chronic low back pain (cLBP) lacks clear physiological explanations, and the treatment options are of limited effect. Here, we elucidate the underlying biology of cLBP in a subgroup of patients with Modic changes type I (suggestive of inflammatory vertebral bone marrow lesions) by correlating gene expression in blood with patient-reported outcomes on disability and pain intensity and explore sex-differences. Patients were included from the placebo group of a clinical study on patients with cLBP and Modic changes. Blood was collected at the time of inclusion, after three months, and after one year, and gene expression was measured at all time points by high-throughput RNA sequencing. The patients reported disability using the Roland Morris Disability Questionnaire, and pain intensity was assessed as a mean of three scores on a 0-10 numeric rating scale: current LBP, worst LBP within the last two weeks, and mean LBP within the last two weeks. The gene expression profiles were then correlated to the reported outcomes. Changes in gene expression over time correlated significantly with changes in both disability and pain. The findings showed distinct patterns in men and women, with negligible overlap in correlated genes between the sexes. The genes involved were enriched in immunological pathways, particularly T cell receptor complex and immune responses related to neutrophils. Several of the genes harbour polymorphisms that previously have been found to be associated with chronic pain. Men and women had distinct sets of correlating genes, suggesting gender differences in the underlying biology of disability and pain in these patients.

CRLF1 involves in intervertebral disc degeneration via exacerbating extracellular matrix degradation and nucleus pulposus cells senescence

Project description:Low back pain (LBP) is one of the most common musculoskeletal disorders with a huge global impact. Intervertebral disc degeneration (IVDD) is an important cause of low back pain. Therefore, it is crucial to identify and elucidate the key factors affecting IVDD. We identified CRLF1, a key molecule in the process of IVDD, by Gene Expression Omnibus dataset, and determined the high expression of CRLF1 within the degenerated discs and in senescent NPCs by IHC, WB. To further explore the effect of CRLF1 on NPCs, we applied RNA-seq to explore the phenotypic changes of NPCs treated with CRLF1.

N6-methyladenosine circRNA Epitranscriptomic Microarray of human nucleus pulposus in intervertebral disc degeneration

Project description:It is well documented that low back pain is a common condition and the leading cause of disability globally. A widely recognised contributor to low back pain is intervertebral disc degeneration (IVDD), which is the major cause of a series of degenerative disc diseases. Recently, it has been reported that circRNAs are involved in the development of IVDD. However, the mechanisms by which m6A modifies circRNA in nucleus pulposus cells remain poorly understood. Here, we aim to identify differentially expressed m6A circRNAs in degenerative nucleus pulposus cells and figure out how the circRNAs regulate IVDD progression and the m6A methylation functions.

Amoxicillin treatment of pneumococcal pneumonia impacts bone marrow neutrophil maturation and function.

Project description:Pneumonia caused by Streptococcus pneumoniae is a leading cause of death worldwide, and bacterial resistance to antimicrobial drugs has become a major issue. A growing body of evidence indicates that the successful treatment of bacterial infections results from synergy between antibiotic-mediated direct antibacterial activity and the host’s immune defenses. However, the mechanisms underlying the protective immune responses induced by amoxicillin (a β-lactam antibiotic used as the first-line treatment of S. pneumoniae infections) have not been characterized. A better understanding of amoxicillin’s effects on host-pathogen interactions might facilitate the development of other treatment options. Given the crucial role of neutrophils in the control of S. pneumoniae infections, we decided to investigate amoxicillin’s impact on neutrophil development in a mouse model of pneumococcal superinfection. Although a single therapeutic dose of amoxicillin prevented local and systemic inflammatory responses, it did not impair the emergency granulopoiesis triggered in the bone marrow by S. pneumoniae. Importantly, treatment of pneumonia with amoxicillin was associated with a greater mature neutrophil count in the bone marrow; these neutrophils had specific transcriptomic and proteomic profiles. Furthermore, amoxicillin-conditioned, mature neutrophils in the bone marrow had a less activated phenotype and might be rapidly mobilized in peripheral tissues in response to systemic inflammation. Thus, by revealing a novel effect of amoxicillin on the development and functions of bone marrow neutrophils during Streptococcus pneumoniae pneumonia, our findings provide new insights into the impact of amoxicillin treatment on host immune responses.
