Abstract
Soluble receptors are soluble forms of receptors found in the extracellular space. They have emerged as pivotal regulators of cellular signaling and disease pathogenesis. This review emphasizes their significance in cancer as diagnostic/prognostic markers and potential therapeutic targets. We provide an overview of the mechanisms by which soluble receptors are generated along with their functions. By exploring their involvement in cancer progression, metastasis, and immune evasion, we highlight the importance of soluble receptors, particularly soluble cytokine receptors and immune checkpoints, in the tumor microenvironment. Although current research has illustrated the emerging clinical relevance of soluble receptors, their therapeutic applications remain underexplored. As the landscape of cancer treatment evolves, understanding and targeting soluble receptors might pave the way for novel strategies for cancer diagnosis, prognosis, and therapy.

Abstract
PURPOSE To examine the safety and effectiveness of the combination of Camrelizumab and Abraxane + lobaplatin in advanced gastric cancer therapy. METHODS The data of 60 patients with advanced gastric cancer in Shaanxi Provincial People's Hospital from May 2017 to March 2019 were analyzed retrospectively. The patients were divided into a study group (n=30) and a control group (n=30) according to different treatment methods. The study group received Camrelizumab combined with the Abraxane + lobaplatin regimen, and the control group received the Abraxane + lobaplatin regimen only. The levels of soluble interleukin-2 receptor (sIL-2R), secretory glycoprotein (Dickkopf-1, DKK-1) and tumor specific growth factors (TSGFs), the relative molecular expression of serum miRNA-1290, miRNA-647 and miRNA-182, and the Karnofsky performance status (KPS) were compared between the two groups. The adverse reactions of the two groups were observed, and the 3-year survival rates were compared. RESULTS The disease control rate and overall remission rate of the study group (53.33%, 90.00%) were higher than those of the control group (26.67%, 50.00%), with statistically significant differences (P<0.05). The levels of sLL-2R, DKK-1 and TSGF were reduced in both groups (P<0.05) after being treated, whereas these were comparatively lower levels in the study group (P<0.05). After treatment, serum concentration of miRNA-1290, miRNA-647 and miRNA-182 were lower in the study group than in the control group (P<0.05). Upon comparison with those in the control group, the KPS scores were higher at 1, 3 and 6 months after treatment in the study group (P<0.05). The incidence of adverse events was not significantly different between the two groups (P>0.05). The 1-year, 2-year and 3-year survival rates were higher in the study group (57.38%, 39.34% and 29.51%) than in the control group (32.79%, 18.03% and 8.20%) (P<0.05). CONCLUSION The combination of Camrelizumab and Abraxane + lobaplatin is an effective treatment for advanced gastric cancer and can increase the patient's survival rate.

Abstract
Cytokines control the immune system by regulating the proliferation, differentiation and function of immune cells. They activate their target cells through binding to specific receptors, which either are transmembrane proteins or attached to the cell-surface via a GPI-anchor. Different tissues and individual cell types have unique expression profiles of cytokine receptors, and consequently this expression pattern dictates to which cytokines a given cell can respond. Furthermore, soluble variants of several cytokine receptors exist, which are generated by different molecular mechanisms, namely differential mRNA splicing, proteolytic cleavage of the membrane-tethered precursors, and release on extracellular vesicles. These soluble receptors shape the function of cytokines in different ways: they can serve as antagonistic decoy receptors which compete with their membrane-bound counterparts for the ligand, or they can form functional receptor/cytokine complexes which act as agonists and can even activate cells that would usually not respond to the ligand alone. In this review, we focus on the IL-2 and IL-6 families of cytokines and the so-called Th2 cytokines. We summarize for each cytokine which soluble receptors exist, were they originate from, how they are generated, and what their biological functions are. Furthermore, we give an outlook on how these soluble receptors can be exploited for therapeutic purposes.

Abstract
OBJECTIVES Chemoradiation can induce immunogenic (ICD) or tolerogenic cell death. ICD relies on the generation of damage-associated molecular patterns which can stimulate toll-like receptors (TLRs). We sought to determine whether we can predict responses to chemoradiation by measuring surrogate biomarkers of ICD in a cohort of patients with locally advanced (LA) head and neck squamous cell carcinoma (HNSCC). MATERIALS AND METHODS In a cohort of 113 LA HNSCC pts we evaluated expression of TLR4, TLR7 and TLR9 in the EpCAM + circulating tumor cell (CTC) fraction at baseline and after cisplatin chemoradiation. We also quantified changes in chemokines CXCL10, CXCL16 and IL-2R in the serum. RESULTS Seventy three patients had evaluable specimens. Among cases with biomarker assessment at baseline and post treatment, 36.8% had an increase in CXCL10 levels (p = 0.022), 73.7% had an increase in CXCL16 levels (p = 0.002) and 63.8% had an increase in IL2Ra levels (p = 0.032) with treatment. 52.0% of evaluable cases at baseline and post-treatment had an increase in TLR4 levels (p = 0.996), 42.9% had an increase in TLR7 levels (p = 0.042) and 27.7% had increase in TLR9 levels (p = 0.011) with treatment. CXCL10 levels at baseline were significantly associated with PFS and OS (p = 0.010 and p = 0.032, respectively). CONCLUSIONS Our results suggest that chemoradiation leads to quantifiable effects in surrogate markers of ICD. These effects may inform trials combining chemoradiation with immune checkpoint inhibitors. In addition, CXCL10 has prognostic effect in pts treated with chemoradiation.

IL-2Rα up-regulation is mediated by latent membrane protein 1 and promotes lymphomagenesis and chemotherapy resistance in natural killer/T-cell lymphoma. Cancer Commun (Lond) 2018; 38:62.

Abstract
BACKGROUND Natural killer/T-cell lymphoma (NKTCL) is a highly aggressive non-Hodgkin lymphoma often resistant to chemotherapy. Serum level of soluble IL-2 receptor α (IL-2Rα) is elevated in NKTCL patients and correlates significantly with treatment response and survival. In the current study we examined the potential role of IL-2Rα by over-expressing IL-2Rα in representative cell lines. METHODS Levels of IL-2Rα were evaluated in the human natural killer cell line NK-92 and the NKTCL cell line SNK-6. Lentiviral vectors were used to express latent membrane protein 1 (LMP1) in NK-92 cells, and IL-2Rα in both NK-92 and SNK-6 cells. The biological effects of these genes on proliferation, apoptosis, cell cycle distribution, and chemosensitivity were analyzed. RESULTS Expression of IL-2Rα was significantly higher in SNK-6 cells than in NK-92 cells. Expressing LMP1 in NK-92 cells remarkably up-regulated IL-2Rα levels, whereas selective inhibitorss of the proteins in the MAPK/NF-κB pathway significantly down-regulated IL-2Rα. IL-2Rα overexpression in SNK-6 cells promoted cell proliferation by altering cell cycle distribution, and induced resistance to gemcitabine, doxorubicin, and asparaginase. These effects were reversed by an anti-IL-2Rα antibody. CONCLUSIONS Our results suggest that LMP1 activates the MAPK/NF-κB pathway in NKTCL cells, up-regulating IL-2Rα expression. IL-2Rα overexpression promotes growth and chemoresistance in NKTCL, making this interleukin receptor a potential therapeutic target.

[PMID: 25879931 PMCID: PMC4400039 DOI: 10.1371/journal.pone.0124151] [Citation(s) in RCA: 68] [Impact Index Per Article: 7.6] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/24/2014] [Accepted: 03/10/2015] [Indexed: 02/07/2023] Open
Abstract
BACKGROUND Carcinoembryonic antigen (CEA) is commonly used as a serum tumor marker in clinical practice; however, its prognostic value for gastric cancer patients remains uncertain. This meta-analysis was performed to assess the prognostic value of CEA and investigate CEA as a tumor marker. METHODS PubMed, EMBASE and other databases were searched for potentially eligible studies. Forty-one studies reporting the prognostic effect of pretreatment serum CEA expression in gastric cancer patients were selected. Data on 14651 eligible patients were retrieved for the meta-analysis. Based on the data extracted from the available literature, the hazard ratio (HR) and 95% confidence interval (CI) for an adverse prognosis were estimated for gastric cancer patients with elevated pretreatment serum levels of CEA (CEA+) relative to patients with normal pretreatment CEA levels (CEA-). RESULTS The CEA+ patients had a significantly poorer prognosis than the CEA- patients in terms of overall survival (OS: HR 1.716, 95% CI 1.594 - 1.848, P< 0.001), disease-specific survival (DSS: HR 1.940, 95% CI 1.563 - 2.408, P< 0.001), and disease-free survival (DFS: HR 2.275, 95% CI 1.836 - 2.818, P< 0.001). Publication bias and an influence of different cut-off values were not observed (all P> 0.05). In the pooled analyses of multivariate-adjusted HRs, the results suggested that pretreatment serum CEA may be an independent prognostic factor in gastric cancer (OS: HR 1.681, 95% CI 1.425 - 1.982; DSS: HR 1.900, 95% CI 1.441 - 2.505; DFS: HR 2.579, 95% CI 1.935 - 3.436). CONCLUSION/SIGNIFICANCE The meta-analysis based on the available literature supported the association of elevated pretreatment serum CEA levels with a poor prognosis for gastric cancer and a nearly doubled risk of mortality in gastric cancer patients. CEA may be an independent prognostic factor for gastric cancer patients and may aid in determining appropriate treatment which may preferentially benefit the CEA+ patients.

Clinical significance of serum soluble interleukin-2 receptor-α in extranodal natural killer/T-cell lymphoma (ENKTL): a predictive biomarker for treatment efficacy and valuable prognostic factor. Med Oncol 2013; 30:723. [PMID: 24037346 DOI: 10.1007/s12032-013-0723-4] [Citation(s) in RCA: 14] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/05/2013] [Accepted: 08/28/2013] [Indexed: 10/26/2022]
Abstract
Extranodal natural killer/T-cell lymphoma, nasal type (ENKTL) is an aggressive disease, and no standard treatment and validated prognostic model were established. Serum sIL-2Rα levels were measured in 94 ENKTL patients to evaluate its relationship with clinical features, treatment response, and prognosis. Serum sIL-2Rα level was 2964 ± 1613.6 ng/L in ENKTL patients, higher than in normal healthy controls (p < 0.05). Using median level (2508.5 ng/L) as cutoff, patients were divided into higher- and lower-level group (N = 47 for each). The complete remission and overall remission rate were significantly higher in lower-level group (p < 0.05). After a median follow-up time of 22.0 months, 2-year overall survival and progression-free survival rates were 60.0 and 53.0 %, respectively. Lower sIL-2Rα level significantly correlated with better progression-free survival (PFS) and overall survival (OS) (p = 0.001 and 0.002, respectively). IPI score and treatment responses after 2 cycles of chemotherapy significantly correlated with PFS and OS (p < 0.05). In a multivariate Cox regression model that included IPI score, treatment responses, and sIL-2Rα level, all three parameters were independent prognostic factors for OS (p = 0.043, 0.001, and 0.025, respectively), and the last two parameters were also independent factors for PFS (p = 0.005 and 0.005, respectively). Elevated serum sIL-2Rα level was related to poor responses to treatments and can be used as a valuable biomarker for disease activity. Moreover, serum sIL-2Rα was an independent prognostic factor for both OS and PFS. These results need to be validated in prospective trials and may support the incorporation of anti-CD25 targeted therapy into the treatment realm of ENKTL.

Abstract
Background: Currently, serum biomarkers, which are sufficiently sensitive and specific for early detection and risk classification of gastric adenocarcinoma do not exist. Therefore, this study identified a panel of serum biomarkers for the diagnosis of gastric adenocarcinoma. Methods: A 29-plex array platform with 29 biomarkers, consisting of 11 proteins discovered through proteomics and 18 previously known to be cancer-associated, was constructed. A test/training set consisting of 120 gastric adenocarcinoma and 120 control samples were examined. After 13 proteins were selected as candidate biomarkers, multivariate classification analyses were used to identify algorithms for diagnostic biomarker combinations. These algorithms were independently validated using a set of 95 gastric adenocarcinoma and 51 control samples. Results: Epidermal growth factor receptor (EGFR), pro-apolipoprotein A1 (proApoA1), apolipoprotein A1, transthyretin (TTR), regulated upon activation, normally T-expressed and presumably secreted (RANTES), D-dimer, vitronectin (VN), interleukin-6, α-2 macroglobulin, C-reactive protein and plasminogen activator inhibitor-1 were selected as classifiers in the two algorithms. These algorithms differentiated between the majority of gastric adenocarcinoma and control serum samples in the training/test set with high accuracy (>88%). These algorithms also accurately classified in the validation set (>85%). Conclusion: Two panels of combinatorial biomarkers, including EGFR, TTR, RANTES, and VN, are developed, which are less invasive method for the diagnosis of gastric adenocarcinoma. They could supplement clinical gastroscopic evaluation of symptomatic patients to enhance diagnostic accuracy.

Abstract
BACKGROUND AND OBJECTIVES Surgery induces lymphocytopenia and this decrease of host defenses, related to interleukin-2 (IL-2) endogenous imbalance during postoperative period could promote the proliferation of possible micrometastases and the implantation of surgically disseminated tumor cells. Moreover, tumor infiltrating lymphocytes (TILs), activated by endogenous IL-2 release, are linked to prognosis in cancer patients. The aim of this randomized study is to assess the biological (peripheral blood cells count, related to the grade of immunosuppression), histological (TILs), and clinical (overall and disease-free survival) impact of preoperative low doses administration of IL-2 in patients with radically operable gastric cancer. METHODS This prospective study enrolled 69 consecutive patients with histologically proven gastric adenocarcinoma who underwent radical surgery from October 1999 to December 2002 (M/F 39/30; mean age 66; range 42-82) who underwent radical surgery from October 1999 to December 2000. Patients were randomized to be treated with surgery alone as controls (35 patients) or surgery plus preoperative treatment with recombinant human IL-2 (34 patients). We considered the total lymphocyte count and lymphocyte subset (CD4, CD4/CD8) during the preoperative period, before IL-2 administration, and on the 14th and 50th day, peritumoral stromal (fibrosis) reaction, neutrophils, lymphocytes, and eosinophils infiltration in tumor histology, and morbidity disease free and overall survival were evaluated. RESULTS Two groups were well matched for type of surgery and extent of disease. All the patients underwent radical surgery plus D2 lymphadenectomy. At baseline, there were no significant differences in total lymphocyte and lymphocyte subsets between groups. The control group showed a significant decrease of total lymphocytes, CD4 cells, and CD4/CD8 ratio at the 14th postoperative day relative to the baseline value. In the control group 65% of patients had a decrease of CD4 under 500 cells/mmc. Instead it has been observed in IL-2 group a significant increase over the control group values of total lymphocytes and CD4 cells (14th total lymphocytes and CD4: IL-2 vs. control P < 0.05). Moreover in this group only 15% patients had CD4 under 500 cells/mmc. This difference, in CD4 count, is significant even at the 50th postoperative day (P = 0.006). IL-2 group showed lower postoperative complications (2/34 vs. 11/35; P < 0.05), and higher lymphocyte/eosinophil infiltration into the tumor (P < 0.0002). Median follow-up was 26 months (range 10-48) and median overall and disease-free survivals were longer, even if not significantly, in the IL-2 group than in the control arm (P = 0.07 and P = 0.06 respectively). CONCLUSIONS This randomized study would suggest that a preoperative immunotherapy with IL-2 is a well-tolerated treatment able to prevent surgery-induced lymphocytopenia. IL-2 seems to neutralize the immunosuppression induced by operation and so to stimulate the host reaction against tumor tissue (lymphocytes/eosinophils infiltration). Furthermore IL-2 seems to have an impact on clinical course reducing morbidity of surgery and ameliorating overall and disease-free survival.
