Abstract
Purpose Clinical studies have demonstrated the intricate association between the onset and progression of obstructive sleep apnea (OSA) and the activation of the inflammatory cascade reaction. This study delves into investigating the causal links between 91 circulating inflammatory proteins (CIPs) and OSA through the application of Mendelian randomization (MR) techniques. Methods Utilizing genetic data on OSA sourced from the Finnish Biobank (FinnGen) Genome-wide Association Studies (GWAS) of the European population, alongside summary-level GWAS data of CIPs from 14,824 European participants, we conducted a bidirectional MR study. Results This study suggests that several factors may be associated with the risk of OSA. IL-17C (odds ratio (OR) = 1.090, p = 0.0311), CCL25 (OR = 1.079, p = 0.0493), FGF-5 (OR = 1.090, p = 0.0003), CD5 (OR = 1.055, p = 0.0477), and TNFSF14 (OR = 1.092, p = 0.0008) may positively correlate with OSA risk. Conversely, IL-20RA (OR = 0.877, p = 0.0107), CCL19 (OR = 0.933, p = 0.0237), MIP-1 alpha (OR = 0.906, p = 0.0042), Flt3L (OR = 0.941, p = 0.0019), CST5 (OR = 0.957, p = 0.0320), OPG (OR = 0.850, p = 0.0001), and TRAIL (OR = 0.956, p = 0.0063) may reduce the risk of OSA. Additionally, elevated levels of IL-10RA (OR = 1.153, p = 0.0478) were observed as a consequence of OSA. Conversely, OSA may potentially lead to decreased levels of CCL28 (OR = 0.875, p = 0.0317), DNER (OR = 0.874, p = 0.0324), FGF-21 (OR = 0.846, p = 0.0344), and CSF-1 (OR = 0.842, p = 0.0396). Conclusion Through this bidirectional MR study, we have identified 12 upstream regulatory proteins and 5 downstream effect proteins that are linked to OSA. These findings hold promise in providing potential therapeutic targets for the inflammatory mechanisms underlying OSA.

Expression of immune regulatory factors, chemokines and growth factors in differentiated gastric cancer cells treated with an anticancer bioactive peptide combined with oxaliplatin. Mol Clin Oncol 2024; 20:9.

Abstract
Gastric cancer is one of the most common malignant tumors of the digestive system. An anticancer bioactive peptide (ACBP) was previously shown to have an important role in inhibiting the differentiation of the MKN-45, N87 and GES-1 cell lines. However, to date, research on the effects of inflammatory factors in MKN-45, N87 and GES-1 cell lines after treatment with ACBP combined with oxaliplatin (OXA) has not been performed. To investigate the expression of immune regulatory factors, tumor growth factors and chemotactic factors in differentiated gastric cancer cells treated with ACBP combined with OXA, the expression of cytokines, including interleukin (IL)-1β, IL-1 receptor antagonist, IL-2, IL-4, IL-6-10, IL-12, IL-13, IL-15, IL-17, Eotaxin, basic fibroblast growth factor (bFGF), granulocyte-macrophage colony-stimulating factor (GM-CSF), interferon (IFN)-γ, monocyte chemoattractant protein (MCP)-1, IFN-γ-induced protein-10, macrophage inflammatory protein (MIP)-1α, platelet-derived growth factor (PDGF)-BB, MIP-1β, regulated upon activation, normal T cell expressed and presumably secreted, TNF-α and VEGF, was assessed with cell experiments using the Bio-Plex ProT Human Cytokine 27-plex Assay. The results indicated that immune regulatory factor, tumor growth factor and chemotactic factor expression levels were different after treatment with ACBP alone or ACBP combined with OXA. IFN-γ, IL-1β, IL-17, IL-9, IL-10, IL-15, bFGF, GM-CSF and PDGF-BB expression was decreased in MKN-45 and N87 cells after ACBP treatment (P<0.01) and ACBP+OXA treatment (P<0.01) compared with the control cells, which indicated that ACBP inhibited tumor growth by regulating these cytokines, and the combination treatment inhibited tumor growth by regulating these cytokines. MIP-1β, MCP-1 and IL-13 expression was decreased in MKN-45 and N87 cells after the combination treatment compared with ACBP treatment alone, which indicated that ACBP combined with OXA was able to inhibit tumor growth by regulating these cytokines, while the mechanism of action of the ACBP and OXA is actually different, e.g. for OXA, this would be to cause DNA damage response. Therefore, the ACBP and OXA combination treatment may be closely associated with tumor progression and metastasis with immunological competence by MCP-1, MIP-1β and IL-13 expression.

Abstract
The central physiological role of the bone marrow renders bone marrow stromal cells (BMSCs) particularly sensitive to aging. With bone aging, BMSCs acquire a differentiation potential bias in favor of adipogenesis over osteogenesis, and the underlying molecular mechanisms remain unclear. Herein, we investigated the factors underlying age-related changes in the bone marrow and their roles in BMSCs' differentiation. Antibody array revealed that CC chemokine ligand 3 (CCL3) accumulation occurred in the serum of naturally aged mice along with bone aging phenotypes, including bone loss, bone marrow adiposity, and imbalanced BMSC differentiation. In vivo Ccl3 deletion could rescue these phenotypes in aged mice. CCL3 improved the adipogenic differentiation potential of BMSCs, with a positive feedback loop between CCL3 and C/EBPα. CCL3 activated C/EBPα expression via STAT3, while C/EBPα activated CCL3 expression through direct promoter binding, facilitated by DNA hypomethylation. Moreover, CCL3 inhibited BMSCs' osteogenic differentiation potential by blocking β-catenin activity mediated by ERK-activated Dickkopf-related protein 1 upregulation. Blocking CCL3 in vivo via neutralizing antibodies ameliorated trabecular bone loss and bone marrow adiposity in aged mice. This study provides insights regarding age-related bone loss and bone marrow adiposity pathogenesis and lays a foundation for the identification of new targets for senile osteoporosis treatment.

Abstract
Endometriosis is a disorder characterized by the presence of endometrial tissue outside the uterine cavity, primarily into the peritoneal cavity. It is known as a complex, chronic inflammatory disease and it is strongly associated with immune dysregulation. Various soluble mediators of the immune and inflammatory responses, including chemokines, play an important role in these processes. The aim of the study was to understand the role of the chemokines MCP-1, MCP-2, MCP-3, MCP-4, MIP-1 α, MIP-1β, eotaxin 2, eotaxin 3, ENA-78, and fractalkine in the development of endometriosis through their assessment in the peritoneal fluid of women with endometriosis. The study group included 58 women with endometriosis who were diagnosed during laparoscopy and then confirmed by histopathology. In 15 women from the reference group, laparoscopic examination demonstrated a normal status of the pelvic organs without any evidence of endometriosis nor inflammation in the peritoneal cavity. The peritoneal fluid of women with endometriosis and of women from the reference group were examined. To determine the concentration of the studied chemokines, enzyme immunoassays for Luminex® platforms were used. In the peritoneal fluid of women with endometriosis, a statistically significant increase in the concentration of MIP-1β, eotaxin 2, eotaxin 3, ENA-78, and fractalkine and a decrease in the concentration of MCP-1, MCP-2, MCP-3, MCP-4, and MIP-1α were observed compared to the reference group. The concentration of these cytokines depended on the severity of the disease. Changes in the concentration of the studied chemokines in the peritoneal fluid of women with endometriosis suggest their participation in the pathogenesis of the disease. The differences in chemokines concentration observed in different stages of endometriosis may be associated with the presence of inflammation in the peritoneal cavity at each step of disease development.

Abstract
Multiple myeloma (MM) is the second most common hematologic malignancy in the world. Even though survival rates have significantly risen over the past years, MM remains incurable, and is also far from reaching the point of being managed as a chronic disease. This paper reviews the evolution of MM therapies, focusing on anti-MM drugs that target the molecular mechanisms of nuclear factor kappa B (NF-κB) signaling. We also provide our perspectives on contemporary research findings and insights for future drug development.

Abstract
Parathyroid hormone-related protein (PTHrP) and macrophage inflammatory protein-1α (MIP-1α) are important factors that increase bone resorption and hypercalcemia in adult T-cell leukemia (ATL). We investigated the role of PTHrP and MIP-1α in the development of local osteolytic lesions in T-cell leukemia through overexpression in Jurkat T-cells. Injections of Jurkat-PTHrP and Jurkat-MIP-1α into the tibia and the left ventricle of NSG mice were performed to evaluate tumor growth and metastasis in vivo. Jurkat-pcDNA tibial neoplasms grew at a significantly greater rate and total tibial tumor burden was significantly greater than Jurkat-PTHrP neoplasms. Despite the lower tibial tumor burden, Jurkat-PTHrP bone neoplasms had significantly greater osteolysis than Jurkat-pcDNA and Jurkat-MIP-1α neoplasms. Jurkat-PTHrP and Jurkat-pcDNA cells preferentially metastasized to bone following intracardiac injection, though the overall metastatic burden was lower in Jurkat-PTHrP mice. These findings demonstrate that PTHrP induced pathologic osteolysis in T-cell leukemia but did not increase the incidence of skeletal metastasis.

Abstract
The purpose of this study was to test the hypothesis that different cytokine profiles may exist in the follicular fluid of endometriosis (EM) patients undergoing in vitro fertilization (IVF), as these differences may provide insights into the pathogenesis of the disease. This was a cross-sectional study conducted at the reproductive center of a medical university hospital. The study included 49 patients receiving IVF. 20 infertile women with proven EM and 29 women without diagnosed EM (control group) were evaluated. Follicular fluid (FF) and serum were collected at the time of follicle aspiration and the concentrations of 38 cytokines were determined by multiplexed immunoassay. The results indicated that the levels of IL-4, IL-13, IL-3 and IL-1α were significantly increased in the FF of women with EM, while levels of IFN-γ, IL-17A, MDC and MIP-1α were decreased compared with in the control subjects. In conclusions, the immune microenvironment of the FF in patients with EM is altered. This may contribute to the pathologic mechanism responsible for the poor outcome of IVF in patients with EM.

Abstract
Osteomyelitis is a frequent consequence of open fractures thus representing a common bone infection with subsequent alteration of bone regeneration. Impaired bone homeostasis provokes serious variations in the bone remodeling process, thereby involving multiple inflammatory cytokines to activate bone healing. Our previously established mouse model of posttraumatic osteomyelitis provides the chance to study regulation of selected cytokines after surgical debridement of osteomyelitis thus illustrating the course of initial infectious recovery. An inflammatory cytokine array revealed specifically upregulated cytokines in debrided animals after bone infection, that were verified by Western blot analysis, identifying increased levels of CCL2, CCL3, and CXCL2. Increased osteoclastogenesis after debridement of osteomyelitis was demonstrated by Calcitonin-receptor and RANKL detection via immunohistochemical and -fluorescence stainings. The substantial protein analysis was complemented by uncovering diminished osteogenesis and proliferation in debrided group, tracking Osteocalcin, RUNX2, and PCNA expression. Interestingly TNF-α expression seemed to have no effect on altered bone regeneration after bone infection. Additional flow cytometry analysis proved elevated B cell activity, subsequently increased osteoclast activity and accelerated bone resorption. Based on the variety of severely altered cytokines, we propose a RANKL-dependent osteoclastogenesis after debridement of osteomyelitis coinciding with elevated B cells and simultaneously decreased osteogenesis. A comprehensive understanding of these mechanisms provides new therapeutic options of osteomyelitis cure and is of great importance in prospective medical treatment. © 2017 Orthopaedic Research Society.

Abstract
OBJECTIVE The NLRP3 inflammasome complex, an important regulatory factor of inflammation and cell apoptosis, has attracted considerable attention in the development of tumor. Here, we analyzed the expression and clinical significance of NLRP3 inflammasome complex and related cytokines in patients with multiple myeloma (MM). METHODS Peripheral blood and bone marrow of 38 newly diagnosed myeloma patients and 25 age- and gender-matched healthy people were studied. NLRP3 and caspase-1 were analyzed using quantitative real-time polymerase chain reaction and Western blot and IL-1beta, IL-18, RANKL, and OPG were evaluated by enzyme-linked immunosorbent assay. RESULTS We showed that aberrant NLRP3 and caspase-1 expression were observed in MM and down-regulated compared with the healthy people. We further demonstrated that NLRP3 mRNA was negatively correlated with beta2-microglobulin and plasma cell percentage in MM. The downstream cytokines IL-18 and sRANKL/OPG in MM patients were higher than that in control group. Moreover, the lower mRNA levels of NLRP3 and caspase-1 were shown to be positively correlated with IL-1beta in newly diagnosed MM patients. CONCLUSIONS This study demonstrated that dysregulated expression of NLRP3-caspase-1-IL-1beta axis was observed in patients with MM, suggesting they might be involved in the pathogenesis of MM.

Abstract
Chronic inflammation in aging is characterized by increased inflammatory cytokines, bone loss, decreased adaptation, and defective tissue repair in response to injury. Aging leads to inherent changes in mesenchymal stem cell (MSC) differentiation, resulting in impaired osteoblastogenesis. Also, the pro-inflammatory cytokines increase with aging, leading to enhanced myelopoiesis and osteoclastogenesis. Bone marrow macrophages (BMMs) play pivotal roles in osteoblast differentiation, the maintenance of hematopoietic stem cells (HSCs), and subsequent bone repair. However, during aging, little is known about the role of macrophages in the differentiation and function of MSC and HSC. Aged mammals have higher circulating pro-inflammatory cytokines than young adults, supporting the hypothesis of increased inflammation with aging. This review will aid in the understanding of the potential role(s) of pro-inflammatory (M1) and anti-inflammatory (M2) macrophages in differentiation and function of osteoblasts and osteoclasts in relation to aging.

Abstract
Background Multiple myeloma is a hematologic malignancy characterized by the accumulation of monoclonal plasma cells in the bone marrow. A common manifestation of the disease is myeloma bone disease (MBD), which is caused by increased osteoclastic bone resorption and decreased bone formation. The chemokine cytokine ligand 3 (CCL3) is a pro-inflammatory protein and chemokine that stimulates osteoclasts in MBD. However, little is known about the effect of CCL3 on osteoblasts (OB). Methods The OBs are induced from patients with MBD and healthy donors, cultured in vitro, and identified by histochemistry. The effects of CCL3 and CCL3 antibody on the OBs in vitro are observed. The CCL3 receptor (CCR1), osteocalcin (OCN), runt-related transcription factor 2 (Runx2), and osterix (Osx) are detected using flow cytometry, enzyme-linked immunosorbent assay, and real-time PCR. Results Proliferation and osteogenic potential of the OB in patients with MBD are suppressed. Moreover, the CCR1 expression is significantly higher in patients with MBD than in normal controls. The OCN level, quantity of calcium nodules, and Runx2 and Osx levels decrease after CCL3 stimulation, which indicates that CCL3 inhibits OB function. Furthermore, CCL3 antibody partially restores OB activity through the upregulation of the OCN, Runx2, and Osx. Conclusions CCL3 contributes to the OB/OC imbalance by inhibiting OB differentiation and function in MBD.

Abstract
Enterococcus faecalis is one of the most common opportunistic pathogens responsible for nosocomial infections, and its LTA is known as an important virulence factor causing inflammatory responses. As chemokines play a key role in inflammatory diseases by triggering leukocyte infiltration into the infection site, we purified EfLTA and investigated its effect on the expression of chemokines, IP-10, MIP-1α, and MCP-1, in murine macrophages. EfLTA induced the expression of these chemokines at the mRNA and protein levels. TLR2, CD14, and MyD88 were involved in the EfLTA-induced chemokine expression, as the expression was reduced remarkably in macrophages derived from TLR2-, CD14-, or MyD88-deficient mice. EfLTA induced phosphorylation of MAPKs and enhanced the DNA-binding activity of NF-κB, AP-1, and NF-IL6 transcription factors. The induction of IP-10 required ERK, JNK, p38 MAPK, PKC, PTK, PI3K, and ROS. We noticed that all of these signaling molecules, except p38 MAPK and ROS, were indispensable for the induction of MCP-1 and MIP-1α. Interestingly, the EfLTA-induced chemokine expression was mediated through PAFR/JAK/STAT1 signaling pathways without IFN-β involvement, which is different from LPS-induced chemokine expression requiring IFN-β/JAK/STAT1 signaling pathways. Furthermore, the culture supernatant of EfLTA-treated RAW 264.7 cells promoted the platelet aggregation, and exogenous PAF induced the chemokine expression in macrophages derived from WT and TLR2-deficient mice. These results suggest that EfLTA induces the expression of chemokines via signaling pathways requiring TLR2 and PAFR, which is distinct from that of LPS-induced chemokine expression.

Abstract
In order to analyze the cai]ses of delayed diagnosis and raise the level of early diagnosis of atypical multiple myeloma (MM), the differences of presenting features between the patients presented to nephrologists and those presented to hematologists were compared. MM patients in our hospital were studied retrospectively. Those who referred renal impairment were divided into two groups: group I presented to nephrologists prior to MM diagnosis (n=29) and group II presented to hematologists directly (n=62). The age, sex, initial symptoms, haematological and biochemical parameters, the phenotype of paraprotein, bone marrow biopsy and cytology were undertaken and analyzed. The results showed that the median time between the initial symptoms and diagnosis in the patients of group I was longer than that in group II (P<0.001); patients in group I had significantly lower incidence of bone pain (P<0.01) and worse renal function (P<0.05) on presentation. There were lower level of myeloma cells (P<0.05), lower incidence of hypergammaglobulinemia (P<0.05), lower positive rate of monoclonal immunoglobulin (M protein) (P<0.05) and M protein level (P<0.05) in the patients of group I than those in group II. The ratio of monoclonal to lambda monoclonal proteins in a population was 1:3.67 in patients of group I, whereas 1:0.90 in patients of group II (P<0.01). Moreover, patients with λ type had a higher degree of renal insufficiency than those with κ type (P<0.05). It was suggested that the median time between the initial symptoms and diagnosis in the patients presented to nephrologists was longer than that in those presented to hematologists; the patients presented to nephrologists had the lower incidence of bone pain, lower level of myeloma cells and M protein, which made early diagnosis more difficult; more patients presented to nephrologists had the majority of λ light chain type, moreover, patients with λ light chain type had a higher incidence of renal insufficiency.

Abstract
Overexpression of fibroblast growth factor receptor 3 (FGFR3) is a hallmark of t(4;14) multiple myeloma (MM). To dissect the mechanism of FGFR3 oncogenesis in MM, we used 3 FGFR selective kinase inhibitors-CHIR258, PD173074, and SU5402-and FGFR3-specific siRNA to modulate FGFR3 activity. Conversely, the ligand FGF was used to stimulate FGFR3 function in human MM cells. The transcriptional response to FGFR3 modification was recorded, and gene expression changes common to all 5 modifiers were documented. Ten genes were commonly regulated. Macrophage inflammatory protein-1 alpha (MIP-1alpha) was the single most differentially altered gene. MIP-1 alpha promoter function, gene expression, and protein secretion were each down-regulated following inhibition of FGFR3 signaling. Down-regulation of MIP-1 alpha was not, however, observed following FGFR3 inhibition in MM cells with RAS mutations implicating RAS-MAPK in MIP-1 alpha regulation. As confirmation, inhibition of ERK1 also down-regulated MIP-1 alpha in FGFR3 inhibitor-resistant cells harboring RAS mutations. MIP-1 alpha is implicated in the survival and proliferation of MM cells and the pathogenesis of MM bone disease. Our observation is the first to directly link an initiating IgH translocation not only to MM-cell growth and survival but also to the disease-associated bone disease.

Abstract
Skin and bone - what comes to mind at hearing this phrase? While certainly a metaphor for disease, it also defines two very different tissues, one a flexible and contiguous outer covering, the other a morphologically diverse hard tissue distributed at over 200 sites in the body. As the accompanying series of Reviews highlights, these tissues are indeed diverse, but there are also surprising similarities. Skin is the interface between the internal organs and the environment, and as such plays a crucial role in the body's defense mechanism. The skin and its many appendages are responsible for functions as diverse as epidermal barrier and defense, immune surveillance, UV protection, thermoregulation, sweating, lubrication, pigmentation, the sensations of pain and touch, and, importantly, the protection of various stem cell niches in the skin. Bone serves a number of purposes: it provides protection for vital organs, a lever for locomotion, a reservoir for calcium, and the site of adult hematopoiesis. The tissue is composed of osteoblasts, osteoclasts, and their individual precursors plus a complex mixture of mesenchymal, myeloid, and lymphoid cells in the marrow space. Finally, the endothelial microenvironment provides nutrition and is a conduit for the influx and emigration of cells that impact bone biology in several important ways. This Review series guides the reader through these various facets of 2 diverse, yet interdependent, tissues.
