C-C Chemokine Receptor 7 in Cancer. Cells 2022; 11:cells11040656. [PMID: 35203305 PMCID: PMC8870371 DOI: 10.3390/cells11040656] [Citation(s) in RCA: 12] [Impact Index Per Article: 6.0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2022] [Revised: 02/01/2022] [Accepted: 02/08/2022] [Indexed: 12/12/2022] Open
Abstract
C-C chemokine receptor 7 (CCR7) was one of the first two chemokine receptors that were found to be upregulated in breast cancers. Chemokine receptors promote chemotaxis of cells and tissue organization. Since under homeostatic conditions, CCR7 promotes migration of immune cells to lymph nodes, questions immediately arose regarding the ability of CCR7 to direct migration of cancer cells to lymph nodes. The literature since 2000 was examined to determine to what extent the expression of CCR7 in malignant tumors promoted migration to the lymph nodes. The data indicated that in different cancers, CCR7 plays distinct roles in directing cells to lymph nodes, the skin or to the central nervous system. In certain tumors, it may even serve a protective role. Future studies should focus on defining mechanisms that differentially regulate the unfavorable or beneficial role that CCR7 plays in cancer pathophysiology, to be able to improve outcomes in patients who harbor CCR7-positive cancers.

Serum LUCAT1 implicates the pathogenesis of muscle-invasive bladder cancer via targeting miR-199a-5p and miR-199b-5p. J Mol Histol 2020; 51:583-591. [PMID: 32844284 DOI: 10.1007/s10735-020-09907-3] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/25/2020] [Accepted: 08/20/2020] [Indexed: 12/24/2022]
Abstract
Muscle-invasive bladder cancer (MIBC) is a common malignancy of urinary system cancers, accounting for about 1/3 of all newly diagnosed bladder cancer cases. Due to its strong metastasis, the 5-year survival of MIBC is less than 50%, and in serious cases, the overall survival of metastatic bladder cancer patients is about 1.3 years. LncRNAs, a type of non-coding RNAs defined as the transcripts exceeding 200 nucleotides in length, are frequently aberrant in multiple cancers including cervical, ovarian, breast and bladder cancers. Recently, LUCAT1 (short for lung cancer-associated transcript 1), a lncRNA first reported to be involved in smoking-related lung cancer, has been observed to exhibit crucial roles in the epithelial-to-mesenchymal transition (EMT), migration and invasion processes of clear cell renal cell carcinoma (ccRCC) and colorectal cancer. However, whether it involves in the pathogenesis of MIBC remains underexplored. In the present study, LUCAT1 was up-regulated in the serum samples of MIBC patients and bladder cancer cell lines, as assessed using real-time PCR. Our in vitro data (including wound healing and trans-well assays) showed that LUCAT1 was required for the proliferation, EMT, migration and invasion processes of T24 cells. Moreover, LUCAT1 directly targeted miR-199a-5p and miR-199b-5p, as affirmed using the luciferase reporter assay, and manipulation of LUCAT1 significantly suppressed miR-199a-5p and miR-199b-5p. Collectively, our findings highlight an axis of LUCAT1/miR-199a/b-5p in MIBC pathogenesis. Therefore, LUCAT1 may possibly be a promising candidate for diagnostic biomarker and therapeutic target of MIBC.

Abstract
Background Expression of C-C chemokine receptor type 7 (CCR7) is associated with the prognosis of several cancers. The aim of this study was to conduct the meta-analysis to determine the prognostic value of CCR7 expression in solid tumors. Materials and methods We searched for relevant literature in the PubMed, Embase, and Cochrane Library databases (last updated on January 15, 2018). The associations of CCR7 expression with overall survival (OS), disease-free survival (DFS), recurrence-free survival (RFS), progress-free survival (PFS), and disease-specific survival (DSS) were estimated. Results In total, 30 qualified studies including 3,413 patients were enrolled. The results revealed that higher expression of CCR7 predicted poorer OS (pooled HR =1.79; 95% CI =1.49–2.16; P<0.001) and PFS (pooled HR =2.18; 95% CI =1.49–3.18; P<0.001), but was not associated with DFS (pooled HR =1.69; 95% CI =0.79–3.61; P=0.175), RFS (pooled HR =1.29; 95% CI =0.48–3.44; P=0.618), or DSS (pooled HR =3.06; 95% CI =0.38–24.83; P<0.294). Conclusion From this meta-analysis, we concluded that high expression of CCR7 in tumor tissue is associated with poor survival in patients with solid tumors, and may be a prognostic biomarker for tumor progression.

Analysis of the prognostic relevance of sex-steroid hormonal receptor mRNA expression in muscle-invasive urothelial carcinoma of the urinary bladder. Virchows Arch 2018; 474:209-217. [PMID: 30483954 DOI: 10.1007/s00428-018-2496-9] [Citation(s) in RCA: 8] [Impact Index Per Article: 1.3] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/08/2018] [Revised: 10/10/2018] [Accepted: 11/19/2018] [Indexed: 12/20/2022]
Abstract
Muscle-invasive urothelial carcinoma of the urinary bladder (UCB) often recurs following radical cystectomy (RC). An altered expression of sex-steroid hormone receptors has been associated with oncological outcomes of UCB and may represent therapeutic targets. Here the expression of different hormone receptors was measured on mRNA levels in patients treated by RC and associated with outcomes. Androgen receptor (AR), estrogen receptor 1 (ESR1), and progesterone receptor (PGR) mRNA expression was assessed by quantitative reverse transcription polymerase chain reaction (RT-qPCR) in RC samples of 87 patients with a median age of 66 (39-88) years. Univariate and multivariate analyses were performed to test associations with pathological and clinical characteristics as well as recurrence-free (RFS) and disease-specific survival (DSS). AR mRNA expression was lower in comparison with ESR1 and PGR expression (p < 0.0001). In univariate analysis, high expression levels of AR were associated with reduced RFS (HR 2.8, p = 0.015) and DSS (HR 2.8, p = 0.010). High AR mRNA expression and a positive lymph node status were independent predictors for reduced RFS (HR 2.5, p = 0.0049) and DSS (HR 3.4, p = 0.009). In patients with low AR mRNA expression, an increased ESR1 and PGR mRNA expression were associated with reduced RFS and DSS. High expression levels of AR are significantly associated with adverse outcome in patients with muscle-invasive UCB following RC. ESR1 and PGR expression status can further stratify patients with low AR expression into subgroups with significantly reduced RFS and DSS. Therapeutic targeting of AR may influence outcomes in patients with UCB.

Abstract
Several lymphangiogenic factors, such as vascular endothelial growth factors (VEGFs), have been found to drive the development of lymphatic metastasis in bladder cancer (BCa). Here, we have analyzed the gene expression of lymphangiogenic factors in tissue specimens from 12 non-muscle invasive bladder cancers (NMIBC) and 11 muscle invasive bladder cancers (MIBC), considering tumor and tumor-adjacent normal bladder areas obtained from the same organs. We then compared the results observed in patients with those obtained after treating human primary bladder microvascular endothelial cells (MEC) with either direct stimulation with VEGF-A or VEGF-C or by co-culturing (trans-well assay) MEC with bladder cancer cell lines varying in VEGF-A and VEGF-C production based on tumor grade. The genes of three markers of lymphatic endothelial commitment and development (PDPN, LYVE-1 and SLP-76) were significantly overexpressed in tissues of MIBC patients showing positive lymphovascular invasion (LVI+), lymph node metastasis (Ln+) and tumor progression. Their expression was also significantly enhanced either after direct stimulation of MEC by VEGF-A and VEGF-C or in the trans-well assay with each bladder cancer cell line. SLP-76 showed the highest gene expression. Both VEGF-A and VEGF-C also enhanced the expression of SLP-76 protein in MEC. However, a correlation between increase of SLP-76 gene expression and the ability of MEC to migrate could only be seen after induction by VEGF-C. The significant expression of SLP-76 in LVI+/Ln+ progressive MIBC and its overexpression in MEC after VEGF-A and VEGF-C stimulation suggest the need to develop this regulator of developmental lymphangiogenesis as a diagnostic tool in BCa.

Abstract
We attempted to analyze the effects of miR-1-3p and CCL2 on the proliferation, migration, and invasion of bladder cancer cells. A total of 18 pairs of bladder cancer tissues with corresponding adjacent tissues and the 6 cases of normal tissues were collected. The expressions of miR-1-3p and CCL2 in the cancer tissues were evaluated using quantitative real-time polymerase chain reaction and western blot. The relationship between miR-1-3p and CCL2 was assessed using luciferase reporter assay. The UM-UC-3 bladder cancer cells were transfected with CCL2 small interfering RNA and miR-1-3p mimics. 3-(4,5-Dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide assay, colony formation assay, wound healing assay, Transwell assay, and the flow cytometry test were used to detect the proliferation, migration, invasion, and apoptosis of bladder cancer cells. Bladder cancer tissues had lower levels of miR-1-3p but higher levels of CCL2 than normal tissues ( p < 0.05). The transfection of miR-1-3p mimics and CCL2 small interfering RNA remarkably suppressed cell proliferation and invasion and promoted apoptosis of cells ( p < 0.05). Results of the luciferase reporter gene assay demonstrated that miR-1-3p targeted CCL2. MiR-1-3p suppresses the proliferation and invasion of urinary bladder cancer cells by targeting CCL2.

Abstract
In this review, we evaluate key molecular pathways and markers of muscle-invasive bladder cancer (MIBC). Overexpression and activation of EGFR, p63, and EMT genes are suggestive of basal MIBC subtype generally responsive to chemotherapy. Alterations in PPARγ, ERBB2/3, and FGFR3 gene products and their signaling along with deregulated p53, cytokeratins KRT5/6/14 in combination with the cellular proliferation (Ki-67), and cell cycle markers (p16) indicate the need for more radical treatment protocols. Similarly, the "bell-shape" dynamics of Shh expression levels may suggest aggressive MIBC. A panel of diverse biological markers may be suitable for simulation studies of MIBC and development of an optimized treatment protocol. We conducted a critical evaluation of PubMed/Medline and SciFinder databases related to MIBC covering the period 2009-2015. The free-text search was extended by adding the following keywords and phrases: bladder cancer, metastatic, muscle-invasive, basal, luminal, epithelial-to-mesenchymal transition, cancer stem cell, mutations, immune response, signaling, biological markers, molecular markers, mathematical models, simulation, epigenetics, transmembrane, transcription factor, kinase, predictor, prognosis. The resulting selection of ca 500 abstracts was further analyzed in order to select the latest publications relevant to MIBC molecular markers of immediate clinical significance.

Abstract
Background To investigate stromal variables including angiogenesis, lymphangiogenesis, and matrix metalloproteinase (MMP) in the serum of patients with urothelial carcinoma of the bladder (UCB) and to evaluate their association with histopathological characteristics and clinical outcome. Material/Methods Protein levels of vascular endothelial growth factors-A, -C, -D (VEGF-A/-C/-D), their receptors- VEGF-R2 and -R3 (VEGF-R2/-R3), and matrix metalloproteinases 2, -3, and -7 (MMP-2, MMP-3, MMP-7) were quantified in the blood serum samples of 71 patients with UCB before radical cystectomy (RC). Samples of patients with non-invasive UCB or no history of UCB were investigated as controls (n=20). Protein levels in the serum were measured using a flow cytometric cytokine assay. Results A positive association for VEGF-D (p<0.001) and an inverse association for MMP-2 (p=0.017) were observed in patients with positive lymph node (LN) status at the time of RC. VEGF-A (p<0.001), VEGF-C (p<0.001), MMP-2 (p<0.001), and MMP-7 (p=0.005) serum levels were different in serum of patients with invasive UCB compared with non-invasive UCB or healthy individuals. None of the serum markers were associated with disease progression. Conclusions High VEGF-D and low MMP-2 serum levels predict LN metastasis in patients with UCB at the time of RC. VEGF-A, VEGF-C, MMP-2, and MMP-7 serum levels varied significantly between invasive and non-invasive disease as well as in comparison with healthy individuals. Clinical implementation of these marker serum measurements may be valuable to select high-risk patients with more invasive or nodal-positive disease.

Abstract
Cigarette smoking is a major risk factor for urothelial cancer (UC) development. However, the associations between smoking and changes in the pathological characteristics and molecular expression of cancer-related molecules in upper tract (UT) UC have not been fully elucidated. We investigated the associations between smoking status and cancer-related factors, including cancer cell proliferation, apoptosis, angiogenesis, lymphangiogenesis and expression of vascular endothelial growth factor-A and -C, matrix metalloproteinase (MMP)-2 and -9, cyclooxygenase (COX)-2 and urokinase-type plasminogen activator, in patients with UTUC. A total of 134 patients who underwent nephroureterectomy were retrospectively investigated. Proliferation index (PI), microvessel density and lymphatic vessel density (LVD) were measured using anti-Ki-67, anti-CD105 and anti-D2-40 antibodies in formalin-fixed specimens. The apoptotic index was evaluated using the terminal deoxynucleotidyl transferase-mediated dUTP nick end labeling method. Other cancer-related molecules were investigated by immunohistochemistry in similar specimens. The patients were divided into three groups; non-smoker (n=54, 40.3%), former smoker (n=46, 34.3%) and current smoker (n=34, 25.4%). The PI and the apoptotic index were not found to be correlated with smoking status; however, the mean/standard deviation level of LVD in current smokers (40.9/12.9) was significantly higher (P=0.034) compared to that in patients who had never smoked (34.4/10.6). In addition, smoking status was positively correlated with the presence of intratumoral lymphatic vessels (iLV) (P=0.010) and the expression of COX-2 and MMP-9 (P=0.032). The multivariate analysis demonstrated that current smoking was independently associated with all the abovementioned smoking-related factors. However, former smoking was correlated with LVD and the presence of iLV. In the survival analysis, LVD, the presence of iLV and the expression of COX-2 and MMP-9 were identified as predictive factors for metastasis following surgery. In conclusion, lymphangiogenesis and the expression levels of COX-2 and MMP-9 were found to be associated with the smoking status of UTUC patients. Our results may provide important insights into the pathological changes precipitated by smoking in these patients.

Abstract
Vascular endothelial growth factor (VEGF) polymorphisms, specifically +405G/C (rs2010963), reportedly influence the risk for various digestive cancers. However, the consequences of these polymorphisms remain controversial and ambiguous. Therefore, we performed a meta-analysis of 11 studies with VEGF +405G/C genotyping on 2,862 patients and 3,028 controls using the random effects model. We obtained a pooled odds ratio (OR) of 1.04 (95% confidence interval (CI) = 0.86-1.26) for the recessive genetic model, 1.07 (95% CI = 0.81-1.42) for the dominant genetic model, 1.09 (95% CI = 0.81-1.47) for the homozygote comparison, and 1.03 (95% CI = 0.83-1.27) for the heterozygote comparison. In the subgroup analysis of the recessive model, the OR was 1.20 (95% CI = 1.02-1.40) in colorectal cancer. These results show that VEGF +405G/C polymorphisms are unlikely to be a major determinant of susceptibility to digestive cancer. Furthermore, the subgroup analysis of recessive model indicates that VEGF +405G/C polymorphisms increase the risk for colorectal cancer.
