FAT4 expression in peripheral blood mononuclear cells is associated with prognosis and immune cell infiltration in hepatocellular carcinoma. Sci Rep 2023; 13:15735.

Abstract
Peripheral blood mononuclear cell (PBMC) genes reflect the host immune status and could be suitable for evaluating the prognosis of patients with hepatocellular carcinoma (HCC), for which a reliable biomarker is unavailable and the host immune responses to cancer cells. This study aimed to investigate prognostically relevant genes in HCC PBMCs and assessed whether their expression represents tumor immune infiltration. Gene expression in PBMCs from patients with advanced or terminal HCC who had survived or died was examined. Correlations among FAT atypical cadherin 4 (FAT4) expression, cancer immune characteristics, and infiltrated immune cell gene marker sets were analyzed. FAT4 expression was lower in the PBMCs of patients with advanced or terminal HCC who had died than that in patients who survived. Kaplan-Meier analysis indicated that FAT4 downregulation was associated with a relatively poor prognosis while overexpression was positively correlated with immune cell infiltration, several immune cell markers, and immune checkpoint expression. Hsa-miR-93-5p represented the most probable upstream microRNA of FAT4. Thus, upregulated FAT4 in PBMCs and HCC tissues might indicate a favorable prognosis and increased immune cell infiltration, while miRNA-93-5p could be a modulator of FAT4 expression. Collectively, these findings suggest novel immunotherapy targets for HCC.

Abstract
The tumor microenvironment that refers to the tumor's surroundings is a key modulator of tumor growth and invasion. The tumor-derived signals are known to downregulate the anti-tumor effects of the effector cells present in the TME. Thus, the cross-talk between the tumor cells with the surrounding immune cells helps in evading the tumor surveillance as well as aiding in tumor growth and proliferation. Hence, knowledge regarding the effects of drugs/compound on the tumor-stromal interactions is gaining importance. In the present study, the effects of jacalin, a dietary lectin on the proliferation and cytokine production of peripheral blood mononuclear cells (PBMCs), are investigated. Jacalin was shown to act as a mitogen of PBMCs, the key cytokine secreting immune cells. Also, jacalin initially induced increased mRNA expression of pro-inflammatory cytokine IFN-γ; however, prolonged stimulation of PBMCs resulted in increased expression of anti-inflammatory cytokine, mainly TGF-β. Furthermore, 6 h jacalin prestimulated PBMCs (Jac-PBMCs) were shown to inhibit HeLa cell proliferation while 24 h Jac-PBMCs were found to favor tumor growth. Thus, it may be postulated that while jacalin initially polarizes the PBMCs to hinder the tumor growth, after a stipulated time point, interaction of jacalin with PBMCs can lead to an immunosuppressive TME that may probably assist in tumor growth and progression.

Perturbation of miR-146b and relevant inflammatory elements in esophageal carcinoma patients supports an immune downregulatory mechanism. Pathol Res Pract 2021; 225:153560. [PMID: 34311393 DOI: 10.1016/j.prp.2021.153560] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Submit a Manuscript] [Subscribe] [Scholar Register] [Received: 03/31/2021] [Revised: 07/10/2021] [Accepted: 07/17/2021] [Indexed: 02/07/2023]
Abstract
BACKGROUND Esophageal Cancer is known as one of the deadliest cancers worldwide with the squamous cell carcinoma (ESCC) being the predominant subtype. There is a growing body of evidence linking the dysregulated microRNA (miRNA) pathway of immune cells to the progression of several tumors. In a previous study, we investigated molecular alterations pertaining to miR-146a and some components of NF-kB signaling pathway and proposed a possible immune downregulatory mechanism in peripheral blood mononuclear cells (PBMCs) of ESCC patients. Here, we further scrutinized other components of this pathway by evaluating PBMC levels of miR-146b, TLR4, IL10, and TNFA. METHODS Gene expressions were quantified using RT-qPCR assays. To prevent the vulnerability of results to the expression instability of reference genes, nine additional transcripts were quantified, and stable reference genes for normalizing qPCR data were identified using the NormFinder and the geNorm algorithms. The efficiency-corrected normalized relative quantity values were used to compare gene expressions among study groups. RESULTS The PBMC expression of miR-146b and TNFA was downregulated in ESCC patients as compared to healthy subjects. While the level of TLR4 was not different among the study groups, the PBMC level of IL10 was upregulated in ESCC patients. Logistic regression analyses coupled with the ROC curve and cross-validation analysis suggested that PBMC expression may serve as potential candidate biomarker for discriminating ESCC patients from healthy subjects. CONCLUSION The present findings, in line with our previous report, propose a particular gene expression pattern in PBMCs of ESCC patients, providing evidence in support of an immune downregulatory mechanism.

Abstract
BACKGROUND/AIM Proinflammatory cytokines play an essential role in the development and progression of prostate cancer (PCa). Especially interleukine (IL-)6 is involved in the development of aggressive PCa. Peripheral blood mononuclear cells (PBMC) have been reported to interact with cancer cells and subsequently lead to increased production of pro-inflammatory cytokines. However, the role of anti-nflammatory cytokines, such as IL-4 is still largely unexplored in prostate cancer. In the present study, we investigated the effects of IL-4 on PBMC co-cultured with PCa cells. MATERIALS AND METHODS PBMC were co-culured with the PCa cell lines LNCaP and LNCaP-IL6+. To avoid cell-cell contact, cancer and immune cells were separated using cell culture inserts with a 0.4 μm pore size membrane. Cell growth was assessed using the [3-(4, 5-dimethylthiazol-2-yl)-2, 5 diphenyl tetrazolium bromide] (MTT) assay. Cytokine levels were measured using a BD™Cytometric Bead Array. RESULTS Cell viability of LNCaP cells decreased massively when cells were co-cultured with PBMC. Pre-incubation with IL-4 could partly rescue the observed effect of cell viability of LNCaP cells co-cultured with PBMC. In contrast, cell viability of the LNCaP-IL6+ cell line was not affected when co-cultured with PBMC. CONCLUSION IL-4 counteracts the cytotoxic effects of PBMC on hormone-sensitive LNCaP cells and is involved in the immune escape and development of aggressive phenotypes of PCa.

Abstract
BACKGROUND Chronic inflammation is thought to influence the risk of prostate cancer. The purpose of this population-based case-control study was to evaluate the association of 48 circulating inflammation markers with prostate cancer, to identify candidate markers for further investigation. METHODS Serum samples collected from 235 prostate cancer patients and 198 population-based controls recruited in Örebro County, Sweden, in 1989-1991, were assessed using a multiplex bead-based immunoassay to determine concentrations of 48 circulating inflammation markers. Logistic regression was first used to evaluate the association between individual markers (highest vs lowest concentration quartile) and prostate cancer in unadjusted and mutually adjusted models. Second, patients with inflammatory conditions, metastatic or advanced prostate cancer, were excluded to address the possible influence of systemic disease on inflammation markers. RESULTS Individual analyses first identified 21 markers associated with prostate cancer (P < .05), which after mutual adjustment were reduced to seven markers. After the exclusion of men with conditions linked with systemic inflammation, associations between prostate cancer and deviant levels of C-X3-C motif chemokine ligand 1, platelet-derived growth factor subunit B homodimer, interleukin 10, C-C motif chemokine ligand (CCL) 21, and CCL11 remained statistically significant. CONCLUSIONS In this explorative study, we identified candidate inflammation markers of possible importance for prostate cancer pathophysiology, for further evaluation in prospective studies.

Abstract
INTRODUCTION We investigated whether the change in the neutrophil lymphocyte ratio (NLR) from the first to the last repeat prostate biopsy (ΔNLR) could be the diagnostic tool or not for prostate cancer (PCa) detection. MATERIALS AND METHODS We retrospectively evaluated medical records of men who had undergone repeat prostate biopsy. The investigated parameters were white blood cell, neutrophil, lymphocyte counts, NLR at the last prostate biopsy, ΔNLR, prostate-specific antigen (PSA), PSA density (PSAD), and PSA velocity. Exclusion criteria were the presence of cancers other than prostate origin, medication, and diseases which induce the change of NLR. RESULTS A total of 301 men who had undergone repeat prostate biopsy were selected for this study. After applying exclusion criteria, 223 patients were included. Of these patients, 94 were diagnosed with PCa (Group I) and 129 with no malignancy (Group II). Only a single patient had metastasis. On evaluating the area under the receiver operating characteristic curve of all study parameters, ΔNLR was the most accurate marker, followed by PSAD and then NLR measured at the last biopsy. CONCLUSIONS ΔNLR was the most accurate marker to improve the total predictive value in repeat prostate biopsy for diagnosing PCa.

Abstract
Background Antioxidant and anti-inflammatory properties of honey have been largely recognized by various studies. Almost all of the potential benefits are associated with polyphenol content. Honey varieties from the arid region are reported to be rich in polyphenols, but data related to its bioactivity in vitro is greatly lacking. This study aimed at establishing the antioxidant and anti-inflammatory properties of arid region honey. Four honey varieties from arid region (H1, H2, H3, and H4) and two popular non-arid region honey (H5 and H6) were tested in vitro in this study. Methods The erythrocyte membrane protection effect of honey varieties were measured by hemolysis assay after exposing erythrocytes to a peroxide generator. The subsequent production of MDA (malondialdehyde) content in erythrocytes was measured. Immunomodulatory effect of the honey varieties was tested in prostate cancer cells PC-3 and PBMC (peripheral blood mononuclear cells) by measuring the IL-6 (interleukin 6) and NO (nitric oxide) levels in cell culture supernatant after incubation with the honey varieties. PC-3 cell viability was assessed after incubation with honey varieties for 24 h. Results Arid region honey exhibited superior erythrocyte membrane protection effect with H4 measuring 1.3 ± 0.042mMTE/g and H2 measuring 1.122 ± 0.018mMTE/g. MDA levels were significantly reduced by honey samples, especially H4 (20.819 ± 0.63 nmol/mg protein). We observed a significant decrease in cell population in PC-3 after 24 h in culture on treatment with honey. A moderate increase in NO levels was observed in both cultures after 24 h at the same time levels of IL-6 were remarkably reduced by honey varieties. Conclusion The results demonstrate the antioxidant effect of arid region honey due to its erythrocyte membrane protection effect and subsequent lowering of oxidative damage as evident from lower levels of lipid peroxidation byproduct MDA. Arid region honey varieties were as good as non-arid region types at decreasing cell viability of prostate cancer cells. The moderate increase in NO levels in PC-3 and PBMCs were not significant enough to elicit any pro-inflammatory response. However, IL-6 secretion was remarkably reduced by all honey varieties in a comparable level indicating the potential anti-inflammatory property of arid region honey.

Abstract
In recent years, many researchers are focusing their attention on the link between inflammation and cancer. The inflammation is involved in the tumor development and suppression, by stimulating the immune response. In particular, the transition from chronic inflammation to cancer produces angiogenic and growth factors able to repair the tissue and to promote cancer cell survival, implantation, and growth. In this contest, the cytokines contribute to the development of these processes becoming active before and during the inflammatory process and playing an important function at the various disease levels. Thus, these proteins can represent specific markers of tumor development and progression. Therefore the "cytokinome" term is used to indicate the evaluation of cytokine pattern by using an "omics" approach. Newly, specific protein chips of considerable and improved sensitivity are being developed to determine simultaneously several and different cytokines. This can be achieved by a multiplex technology that, through the use of small amounts of serum or other fluids, is used to determine the presence and the levels of underrepresented cytokines. Since this method is an accurate, sensitive, and reproducible cytokine assay, it is already used in many different studies. Thus, this review focuses on the more latest aspects related to cytokinome profile evaluation in different cancers.

Abstract
BACKGROUND Few studies have investigated prostate cancer patients' experiences of cognitive functioning or neurobehavioral symptoms (i.e., behavioral changes associated with neurological dysfunction) following androgen deprivation therapy (ADT). METHODS Semi-structured interviews conducted from the US by phone and in-person were used to explore and characterize the: 1) experience of cognitive and neurobehavioral functioning in non-metastatic prostate cancer patients undergoing ADT (n = 19) compared with patients who had not undergone ADT (n = 20); 2) perceived causes of cognitive and neurobehavioral symptoms; 3) impact of these symptoms on quality of life; and 4) strategies used to cope with or compensate for these symptoms. Neuropsychological performance was assessed to characterize the sample. RESULTS Overall, ADT patients experienced marginally more cognitive problems than non-ADT (nADT) patients even though there were no significant differences between groups in neuropsychological performance. ADT patients also experienced more declines in prospective memory and multi-tasking than nADT patients. Significant proportions of participants in both groups also experienced retrospective memory, attention and concentration, and information processing difficulties. With respect to neurobehavioral symptoms, more ADT patients experienced emotional lability and impulsivity (both aspects of disinhibition) than nADT patients. Among the causes to which participants attributed declines, both groups attributed them primarily to aging. A majority of ADT patients also attributed declines to ADT. For both groups, increased cognitive and neurobehavioral symptoms negatively impacted quality of life, and most participants developed strategies to ameliorate these problems. CONCLUSION ADT patients are more vulnerable to experiencing specific cognitive and neurobehavioral symptoms than nADT patients. This study highlights the importance of capturing: a) cognitive symptoms not easily detected using neuropsychological tests; b) neurobehavioral symptoms that can be confused with psychological symptoms, and c) causal beliefs that may affect how people cope with these symptoms. Effective interventions are needed to assist prostate cancer patients in managing these symptoms.

Abstract
Prostate cancer is the most common malignancy in males and easily develops to be aggressive which is closely related to the chronic inflammatory tumor microenvironment in situ. This study aimed to assess the immunoglobulin G (IgG) subclass of B cells and explore their interactions with T follicular helper (Tfh) subsets in prostate cancer patients. The percentages of peripheral blood naïve B cells, memory B cells and mature B cells, as well as Tfh1, Tfh2 and Tfh17 cells were analyzed or sorted by FACSAria. The ratios of the different IgG subclasses (IgG1, IgG2, IgG3 and IgG4) were detected by ELISA, and the expression levels of CXCR3 and CCR6 were measured using RT-PCR and western blot analysis. Meanwhile a co-culture system of B and Tfh cells was to assess the effect of each Tfh subset on the antibody subclass switching of B cells in vitro. We observed higher percentages of 3 Tfh subsets and IgG4+ B cells in the patients with prostate cancer than that in the health controls and proved a positive correlation between Tfh2 and IgG4+ B cells. Then we verified that IL-4, IL-6, IL-10 and prostaglandin E2 (PGE2) effectively promoted antibody class switching of B cells, which may be mediated by inducing Tfh2 cells, yet the study was not completely dependent on Tfh cells. The results provide evidence of the B cell response to an immune suppressive environment by evaluating IgG4 antibodies, and established a relationship between IgG4+ B cells and Tfh2 cells. Clarification of lymphocyte functions in the inflammatory microenvironment of tumors will be of potential therapeutic value.

Do androgen deprivation drugs affect the immune cross-talk between mononuclear and prostate cancer cells? Biomed Pharmacother 2013; 68:21-4. [PMID: 24406295 DOI: 10.1016/j.biopha.2013.12.007] [Citation(s) in RCA: 10] [Impact Index Per Article: 0.9] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 11/06/2013] [Accepted: 12/10/2013] [Indexed: 12/13/2022] Open
Abstract
The aim of the study was to examine the effect of androgen deprivation drugs, i.e. leuprolide and bicalutamide on the immune cross-talk between human peripheral blood mononuclear cells (PBMC) and cells from PC-3 and LNCaP human prostate cancer lines. PBMC, PC-3 and LNCaP were separately incubated without and with two androgen-deprivation drugs, i.e. leuprolide and bicalutamide, and the secretion of IL-1β, IL-6, IL-1ra and IL-10 was examined. In addition, the effect of both drugs on the production of those cytokines was carried out after 24 hours incubation of PBMC with both types of cancer cells. Leuprolide or bicalutamide did not affect the production of the cytokines by PBMC or by the prostate cancer cells from the two lines. Incubation of PBMC with PC-3 or LNCaP cells caused increased production of IL-1β, IL-6 and IL-10 as compared with PBMC incubated without malignant cells. While 10(-7) M and 10(-8) M of leuprolide caused a decreased secretion of IL-1β by PBMC previously incubated with prostate cancer cells without the drug, bicalutamide did not affect this PBMC activity at any drug concentration. This observation suggests the existence of an additional mechanism explaining the effect of androgen deprivation therapy in prostate cancer patients.

Evidence for a pro-proliferative feedback loop in prostate cancer: the role of Epac1 and COX-2-dependent pathways. PLoS One 2013; 8:e63150. [PMID: 23646189 PMCID: PMC3640024 DOI: 10.1371/journal.pone.0063150] [Citation(s) in RCA: 23] [Impact Index Per Article: 2.1] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/09/2013] [Accepted: 03/29/2013] [Indexed: 12/15/2022] Open
Abstract
Objective In human prostate cancer cells, a selective Epac agonist, 8-CPT-2Me-cAMP, upregulates cell proliferation and survival via activation of Ras-MAPK and PI- 3-kinase-Akt-mTOR signaling cascades. Here we examine the role of inflammatory mediators in Epac1-induced cellular proliferation by determining the expression of the pro-inflammatory markers p-cPLA2, COX-2, and PGE2 in prostate cancer cells treated with 8-CPT-2Me-cAMP. Methods We employed inhibitors of COX-2, mTORC1, and mTORC2 to probe cyclic AMP-dependent pathways in human prostate cancer cells. RNAi targeting Epac1, Raptor, and Rictor was also employed in these studies. Results 8-CPT-2Me-cAMP treatment caused a 2–2.5-fold increase of p-cPLA2S505, COX-2, and PGE2 levels in human prostate cancer cell lines. Pretreatment of cells with the COX-2 inhibitor SC-58125 or the EP4 antagonist AH-23848, or with an inhibitor of mTORC1 and mTORC2, Torin1, significantly reduced the Epac1-dependent increase of p-cPLA2 and COX-2, p-S6-kinaseT389, and p-AKTS473. In addition, Epac1-induced protein and DNA synthesis were greatly reduced upon pretreatment of cells with either COX-2, EP4, or mTOR inhibitors. Transfection of prostate cancer cells with Epac1 dsRNA, Raptor dsRNA, or Rictor dsRNA profoundly reduced Epac1-dependent increases in p-cPLA2 and COX-2. Conclusion We show that Epac1, a downstream effector of cAMP, functions as a pro-inflammatory modulator in prostate cancer cells and promotes cell proliferation and survival by upregulating Ras-MAPK, and PI 3-kinase-Akt-mTOR signaling.

[PMID: 23549045 PMCID: PMC3580310 DOI: 10.4111/kju.2013.54.2.85] [Citation(s) in RCA: 13] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Key Words] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 08/24/2012] [Accepted: 10/20/2012] [Indexed: 11/18/2022] Open
Abstract
Purpose C-reactive protein (CRP) is a general marker for inflammation and it has been associated with prostate cancer. We hypothesized that a correlation may exist between CRP and prostate cancer in patients undergoing transrectal biopsy of the prostate because of rising prostate-specific antigen (PSA) levels. Materials and Methods From January 2009 to March 2012, we retrospectively reviewed 710 patients who visited our urology department and were diagnosed as having a PSA value over 4.0 ng/mL. Patients with acute infections, rheumatoid arthritis, gout, asthma, chronic lung disease, myocardial infarction, or apoplexy and those who had taken nonsteroidal anti-inflammatory drugs were exempted from the research because these variables could have impacted CRP. After we applied the exclusion criteria, we selected 63 patients with prostate cancer and 140 patients with benign prostatic hyperplasia (BPH). Results A total of 203 patients were observed: 140 patients had BPH, and 63 patients had prostate cancer. Prostate cancer patients were divided into two groups by tumor-node-metastasis classification. The patients below T2 were group A, and those above T3 were group B. The natural logarithm of C-reactive protein (lnCRP) differed between the BPH group and the prostate cancer group. The lnCRP also differed between the BPH group and prostate cancer groups A and B (p<0.05). Conclusions The serum CRP level of the prostate cancer group was higher than that of the BPH group. Inflammation may be correlated with prostate cancer according to the serum CRP level.
