[PMID: 37702808 DOI: 10.1007/s00432-023-05371-0] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/20/2023] [Accepted: 08/29/2023] [Indexed: 09/14/2023]
Abstract
BACKGROUND Although targeted therapies and immunotherapy have achieved significant clinical benefits in patients with certain pathological types of lung cancer. However, prognosis for patients with lung adenocarcinoma still remains unsatisfactory. It is of extremely importance to find ideal prognostic indicators to predict the prognosis of lung adenocarcinoma patients, especially for patients with early and locally advanced-stage lung adenocarcinoma. The purpose of this study is to elucidate the significance of Insulin-like growth factor receptor 1 (IGFR1) and Vascular endothelial growth factor A (VEGF-A) expression in predicting progression-free survival (PFS) and overall survival (OS) in patients with early and locally advanced-stage lung adenocarcinoma. METHODS In this study, IGFR1 and VEGF-A expression on 119 specimens of patients early and locally advanced-stage lung adenocarcinoma were analyzed by immunohistochemistry with an H-score system. RESULTS Both high IGFR1 expression and VEGF-A expression patients were resulted in 59 (49.6%) separately. The numbers and proportions of IGFR1-&VEGF-A- subgroup, IGFR1-&VEGF-A+ subgroup, IGFR1+&VEGF-A- subgroup and IGFR1+&VEGF-A+ subgroup are 23 (19.3%), 37 (31.1%), 37 (31.1%) and 22 (18.5%) respectively. High IGFR1 expression was significantly associated with both poor PFS and OS of all patients in a univariate analysis. Multivariable analysis showed that patients with IGFR1+&VEGF-A+ expression exhibited a worst PFS and OS in the subgroup of lung adenocarcinoma patients with EGFR mutation. CONCLUSIONS These results suggest that IGFR1+&VEGF-A+ is expected to be a disadvantageous factor for prognosis in the subgroup of EGFR mutation in patients with early and locally advanced-stage lung adenocarcinoma. What's more, this study may provide the theoretical possibility to screen optimal population for a combination therapy with anti-VEGF and anti-IGFR1 in patients with early and locally advanced-stage lung adenocarcinoma.

Abstract
Background/aim The role of PD-L1 in regulating the immunosuppressive tumor microenvironment via its binding on PD-1 receptors is extensively studied. The PD-1/PD-L1 axis is a significant way of cancer immune escape, and PD-L1 expression on tumor cells is suggested as a predictive marker for anti-PD-1/PD-L1 monoclonal antibodies (MoAbs). However, the tumor-intrinsic role of PD-L1 is not known well. Therefore, we aimed to investigate the effects of anti-PD-L1 antibodies on the expression of angiogenesis and metastasis-related genes in tumor cells. Materials and methods The experiments were done with prostate cancer and melanoma cells with low PD-L1 expression (<5%) and prostate and breast cancer cells with high PD-L1 expression (>50%). The gene and protein expressions of VEGFA, E-cadherin, TGFβ1, EGFR, and bFGF in tumor cells were assayed at the 3 different doses of the anti-PD-L1 antibody. Results We found that VEGFA, E-cadherin and TGFβ1 expressions increased in PD-L1 high cells but decreased in PD-L1 low cells after anti-PD-L1 treatment. EGFR expression levels were variable in PD-L1 high cells, while decreased in PD-L1 low cells upon treatment. Also, the anti-PD-L1 antibody was found to increase bFGF expression in the prostate cancer cell line with high PD-L1 expression. Conclusion Our results suggest that the binding of PD-L1 on tumor cells by an anti-PD-L1 monoclonal antibody may affect tumor-intrinsic mechanisms. The activation of angiogenesis and metastasis-related pathways by anti-PD-L1 treatment in PD-L1 high tumors might be a tumor-promoting mechanism. The decrease of VEGFA, TGFβ1 and EGFR upon anti-PD-L1 treatment in PD-L1 low tumor cells provides a rationale for the use of those antibodies in PD-L1 low tumors.

Abstract
INTRODUCTION Complement C5a is an important component of the innate immune system. An increasing number of reports have revealed the relevance of C5a in tumor progression; however, its exact role in metastatic renal cell carcinoma (mRCC) remains unknown. METHODS We evaluated C5a expression in tumor tissue microarrays of 231 mRCC patients and analyzed the relationship between C5a levels and clinical outcomes, and the expression of epithelial-mesenchymal transition (EMT)-related proteins, programmed cell death protein 1 (PD-1), and programmed cell death-ligand 1 (PD-L1). In-vitro functional experiments using exogenous C5a stimulation and C5a silencing in renal cell carcinoma cells were used to validate the tissue findings. RESULTS High C5a expression was associated with poor therapeutic responses, poor overall and progression-free survival, and high expression of EMT-related proteins and PD-1/PD-L1 in mRCC patients. Exogenous C5a promoted proliferation, migration, and invasion of renal cell carcinoma cells, and induced the expression of EMT-related proteins and PD-1/PD-L1. Conversely, C5a silencing inhibited migration and invasion of renal cell carcinoma cells and decreased the expression of EMT-related proteins and PD-1/PD-L1. CONCLUSIONS Our findings indicate that elevated C5a expression is associated with poor outcomes in patients with mRCC, and this effect may be partly attributed to the ability of C5a to promote EMT and PD-1/PD-L1 expression. C5a may be a potential novel target for the treatment of mRCC.

Cancer Gene Ther 2023; 30:277-287.

Abstract
Cytokine-induced killer (CIK) cells are heterogeneous cells composed mainly of CD3+CD56+ T cells. As an important treatment method of adoptive therapy, it has shown promising efficacy in many clinical trials, especially in combination with multidrug therapy. However, the maximal antitumor efficacy of CIK therapy in the combined administration of multidrug and CIK therapies and which administration scheme can maximize the antitumor efficacy of CIK therapy are still remain unclear. In this study, we observed that pemetrexed administration prior to the injection of CIK cells maximizes the efficacy of CIK therapy. Anti-PD-1 mAbs should be administered prior to CIK cell injection to maximize the efficacy of the therapy. However, administering anti-PD-1 mAbs after CIK cell injection significantly affects the binding rate of anti-PD-1 mAbs to the PD-1 receptor on CIK cells, affecting the efficacy of the antitumor therapy. In conclusion, our study observed that a rational administration sequence of pemetrexed combined with CIK therapy and anti-PD-1 mAbs significantly promotes the efficacy of CIK therapy, providing an experimental basis for the combination therapy mode and regimen of CIK therapy in clinical practice. We hope that this study can provide patients with lung adenocarcinoma with a prolonged survival time.

Abstract
Background Early clinical trials indicate that patients with anaplastic lymphoma kinase (ALK)‐driven non‐small cell lung cancer (NSCLC) have a lower response rate to programmed cell death protein 1 (PD‐1) antibody therapy. However, the specific mechanism underlying this remains unclear. To further explore the characteristics of the tumor microenvironment and determine the potential mechanism of immunotherapy resistance in patients with ALK, we selected another important immune‐related molecule, major histocompatibility complex class I (HLA‐I), as the focus of our study. Methods We collected the biopsy samples of 140 patients with NSCLC. The number of CD8+ T cells and HLA‐I/programmed cell death 1 ligand 1 (PD‐L1) expression were determined by immunohistochemistry. Disease‐free survival (DFS) and overall survival (OS) were analyzed using the Kaplan–Meier method, and their relationship with patient clinical characteristics analyzed using Cox proportional hazards regression. In addition, we treated ALK‐positive lung cancer cells with ALK inhibitors in vitro to observe changes of HLA‐I. Results ALK positivity was associated with low membrane PD‐L1 and HLA‐I expression. However, these two indicators were not associated with the prognosis of patients with stage I–IIIa NSCLC. Inhibition of ALK could upregulate HLA‐I membrane expression to a certain extent. Conclusion Patients with ALK fusion showed downregulation of PD‐L1 and HLA‐I expression on the tumor cell membrane. Inhibition of ALK and its downstream signaling pathway can reverse it. These results suggest that the appropriate combination therapy should be considered for patients with ALK fusion and using targeted therapy at the proper time may increase patient benefits.

Abstract
Simple Summary Hypoxia is a common feature of lung cancers. Nonetheless, no guidelines have been established to integrate hypoxia-associated biomarkers in patient management. Here, we discuss the current knowledge and provide translational novel considerations regarding its clinical detection and targeting to improve the outcome of patients with non-small-cell lung carcinoma of all stages. Abstract Lung cancer represents the first cause of death by cancer worldwide and remains a challenging public health issue. Hypoxia, as a relevant biomarker, has raised high expectations for clinical practice. Here, we review clinical and pathological features related to hypoxic lung tumours. Secondly, we expound on the main current techniques to evaluate hypoxic status in NSCLC focusing on positive emission tomography. We present existing alternative experimental approaches such as the examination of circulating markers and highlight the interest in non-invasive markers. Finally, we evaluate the relevance of investigating hypoxia in lung cancer management as a companion biomarker at various lung cancer stages. Hypoxia could support the identification of patients with higher risks of NSCLC. Moreover, the presence of hypoxia in treated tumours could help clinicians predict a worse prognosis for patients with resected NSCLC and may help identify patients who would benefit potentially from adjuvant therapies. Globally, the large quantity of translational data incites experimental and clinical studies to implement the characterisation of hypoxia in clinical NSCLC management.

Abstract
BACKGROUND Poorly differentiated endometrioid adenocarcinoma and serous adenocarcinoma represent an aggressive subtype of endometrial cancer (EC). Programmed death-ligand-1 (PD-L1) was known to exhibit a tumor cell-intrinsic function in mediating immune-independent tumor progression. However, the functional relevance of tumor cell-intrinsic PD-L1 expression in aggressive EC cells and the mechanisms regulating its expression remain unknown. METHODS PD-L1 expression in 65 EC tissues and 18 normal endometrium samples was analyzed using immunohistochemical staining. The effects of PD-L1 on aggressive EC cell growth, migration and invasion were investigated by cell functional assays. Luciferase reporter assays were used to reveal the microRNA-216a (miR-216a)-dependent mechanism modulating the expression of PD-L1. RESULTS Positive PD-L1 expression was identified in 84% of benign cases but only in 12% of the EC samples, and the staining levels of PD-L1 in EC tissues were significantly lower than those in the normal tissues. Higher PD-L1 expression predicts favorable survival in EC. Ectopic expression of PD-L1 in aggressive EC cells results in decreased cell proliferation and the loss of mesenchymal phenotypes. Mechanistically, PD-L1 exerts the anti-tumor effects by downregulating MCL-1 expression. We found that PD-L1 levels in aggressive EC cells are regulated by miR-216a, which directly targets PD-L1. We further identified a mechanism whereby the long non-coding RNA MEG3 represses the expression of miR-216a, thereby leading to increased PD-L1 expression and significant inhibition of cell migration and invasion. CONCLUSION These results reveal an unappreciated tumor cell-intrinsic role for PD-L1 as a tumor suppressor in aggressive EC cells, and identify MEG3 and miR-216a as upstream regulators of PD-L1.

Abstract
Background: Although immunotherapy with checkpoint inhibitors is changing the face of lung adenocarcinoma (LUAD) treatments, only limited patients could benefit from it. Therefore, we aimed to develop an immune-relevant-gene-based signature to predict LUAD patients' prognosis and to characterize their tumor microenvironment thus guiding therapeutic strategy. Methods and Materials: Gene expression data of LUAD patients from Gene Expression Omnibus (GEO) and The Cancer Genome Atlas (TCGA) were systematically analyzed. We performed Cox regression and random survival forest algorithm to identify immune-relevant genes with potential prognostic value. A risk score formula was then established by integrating these selected genes and patients were classified into high- and low-risk score group. Differentially expressed genes, infiltration level of immune cells, and several immune-associated molecules were further compared across the two groups. Results: Nine hundred and fifty-four LUAD patients were enrolled in this study. After implementing the 2-steps machine learning screening methods, 12 immune-relevant genes were finally selected into the risk-score formula and the patients in high-risk group had significantly worse overall survival (HR = 10.6, 95%CI = 3.21–34.95, P < 0.001). We also found the distinct immune infiltration patterns in the two groups that several immune cells like cytotoxic cells and immune checkpoint molecules were significantly enriched and upregulated in patients from the high-risk group. These findings were further validated in two independent LUAD cohorts. Conclusion: Our risk score formula could serve as a powerful and accurate tool for predicting survival of LUAD patients and may facilitate clinicians to choose the optimal therapeutic regimen more precisely.

[PMID: 32366856 PMCID: PMC7198575 DOI: 10.1038/s41419-020-2511-3] [Citation(s) in RCA: 88] [Impact Index Per Article: 22.0] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/12/2020] [Revised: 04/16/2020] [Accepted: 04/17/2020] [Indexed: 12/17/2022]
Abstract
Aberrant vascular network is a hallmark of cancer. However, the role of vascular endothelial cells (VECs)-expressing PD-L1 in tumor immune microenvironment and antiangiogenic therapy remains unclear. In this study, we used the specimens of cancer patients for immunohistochemical staining to observe the number of PD-L1+ CD34+ VECs and infiltrated immune cells inside tumor specimens. Immunofluorescence staining and flow cytometry were performed to observe the infiltration of CD8+ T cells and FoxP3+ T cells in tumor tissues. Here, we found that PD-L1 expression on VECs determined CD8+ T cells’, FoxP3+ T cells’ infiltration, and the prognosis of patients with lung adenocarcinoma. Anlotinib downregulated PD-L1 expression on VECs through the inactivation of AKT pathway, thereby improving the ratio of CD8/FoxP3 inside tumor and remolding the immune microenvironment. In conclusion, our results demonstrate that PD-L1 high expression on VECs inhibits the infiltration of CD8+ T cells, whereas promotes the aggregation of FoxP3+ T cells into tumor tissues, thus becoming an “immunosuppressive barrier”. Anlotinib can ameliorate the immuno-microenvironment by downregulating PD-L1 expression on VECs to inhibit tumor growth.

Network Pharmacology Study on the Pharmacological Mechanism of Cinobufotalin Injection against Lung Cancer. EVIDENCE-BASED COMPLEMENTARY AND ALTERNATIVE MEDICINE 2020; 2020:1246742. [PMID: 32148531 PMCID: PMC7048923 DOI: 10.1155/2020/1246742] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.8] [Reference Citation Analysis] [Abstract] [Track Full Text] [Download PDF] [Figures] [Subscribe] [Scholar Register] [Received: 10/03/2019] [Revised: 12/17/2019] [Accepted: 01/07/2020] [Indexed: 02/06/2023]
Abstract
Cinobufotalin injection, extracted from the skin of Chinese giant salamander or black sable, has good clinical effect against lung cancer. However, owing to its complex composition, the pharmacological mechanism of cinobufotalin injection has not been fully clarified. This study aimed to explore the mechanism of action of cinobufotalin injection against lung cancer using network pharmacology and bioinformatics. Compounds of cinobufotalin injection were determined by literature retrieval, and potential therapeutic targets of cinobufotalin injection were screened from Swiss Target Prediction and STITCH databases. Lung-cancer-related genes were summarized from GeneCards, OMIM, and DrugBank databases. The pharmacological mechanism of cinobufotalin injection against lung cancer was determined by enrichment analysis of gene ontology and Kyoto Encyclopedia of Genes and Genomes, and protein-protein interaction network was constructed. We identified 23 compounds and 506 potential therapeutic targets of cinobufotalin injection, as well as 70 genes as potential therapeutic targets of cinobufotalin injection in lung cancer by molecular docking. The antilung cancer effect of cinobufotalin injection was shown to involve cell cycle, cell proliferation, antiangiogenesis effect, and immune inflammation pathways, such as PI3K-Akt, VEGF, and the Toll-like receptor signaling pathway. In network analysis, the hub targets of cinobufotalin injection against lung cancer were identified as VEGFA, EGFR, CCND1, CASP3, and AKT1. A network diagram of “drug-compounds-target-pathway” was constructed through network pharmacology to elucidate the pharmacological mechanism of the antilung cancer effect of cinobufotalin injection, which is conducive to guiding clinical medication.

Qin T, Xia J, Liu S, Wang J, Liu H, Zhang Y, Jia Y, Li K. Clinical importance of VEGFC and PD-L1 co-expression in lung adenocarcinoma patients. Thorac Cancer 2020; 11:1139-1148. [PMID: 32154654 PMCID: PMC7180596 DOI: 10.1111/1759-7714.13354] [Citation(s) in RCA: 2] [Impact Index Per Article: 0.5] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/16/2019] [Revised: 01/20/2020] [Accepted: 01/24/2020] [Indexed: 12/25/2022] Open
Abstract
Background Vascular endothelial growth factor C (VEGFC), an activator of lymphangiogenesis, is newly identified as an immunomodulator which can regulate the immune system so that tumor cells more easily escape immune surveillance. Evidence has shown programmed cell death‐ligand 1 (PD‐L1) can also suppress the immune response. Nevertheless, the clinical significance of co‐expression of VEGFC and PD‐L1 for predicting outcomes in patients with lung adenocarcinoma has not yet been determined. Methods A total of 114 patients with lung adenocarcinoma who underwent surgeries at Tianjin Medical University Cancer Institute and Hospital between December 2011 and September 2016 were retrospectively reviewed. Tissue specimens were collected for immunohistochemistry of VEGFC and PD‐L1 which were analyzed with an H‐score system. Results In this study, 57 (50.0%) and 47 (41.2%) patients were classified as VEGFC high expression and PD‐L1 high expression. Co‐expression was observed in 33 (28.9%) patients. In addition, a positive correlation was found between VEGFC and PD‐L1 (P = 0.0398, r = 0.1937). In a univariate analysis, both progression‐free survival (PFS) and overall survival (OS) were significantly worse in the VEGFC high expression group and the PD‐L1 high expression group, respectively. Furthermore, VEGFC/PD‐L1 co‐expression showed a worse OS (P = 0.03) and PFS survival (P = 0.01) than the other groups. Conclusions Taken together, these results indicate that VEGFC/PD‐L1 co‐expression can forecast both poor OS and PFS in patients with resected lung adenocarcinoma. Co‐expression of VEGFC and PD‐L1 may serve as a significant prognostic factor for patients with lung adenocarcinoma. Key points VEGFC/PD‐L1 co‐expression forecasts poor survival in patients with resected lung adenocarcinoma. VEGFC/PD‐L1 co‐expression may be used as a prognostic indicator and provide the theoretical possibility to screen the optimal population with a combination of anti‐VEGFC and anti‐PD‐L1 therapy in the clinical treatment.

Abstract
Hepatocellular carcinoma (HCC) has become one of the major diseases that are threatening human health in the 21st century. Currently there are many approaches to treat liver cancer, but each has its own advantages and disadvantages. Among various methods of treating liver cancer, natural medicine treatment has achieved promising results because of their superiorities of high efficiency and availability, as well as low side effects. Alkaloids, as a class of natural ingredients derived from traditional Chinese medicines, have previously been shown to exert prominent anti-hepatocarcinogenic effects, through various mechanisms including inhibition of proliferation, metastasis and angiogenesis, changing cell morphology, promoting apoptosis and autophagy, triggering cell cycle arrest, regulating various cancer-related genes as well as pathways and so on. As a consequence, alkaloids suppress the development and progression of liver cancer. In this study, the mechanisms of representative alkaloids against hepatocarcinoma in each class are described systematically according to the structure classification, which mainly divides alkaloids into piperidine alkaloids, isoquinoline alkaloids, indole alkaloids, terpenoids alkaloids, steroidal alkaloids and other alkaloids. Besides using them alone, synergistic effects created together with other chemotherapy drugs and some special preparation methods also have been demonstrated. In this review, we have summarized the potential roles of several common alkaloids in the prevention and treatment of HCC, by revising the preclinical studies, highlighting the potential applications of alkaloids when they function as a therapeutic choice for HCC treatment, and integrating them into clinical practices.

Abstract
The ligation of programmed cell death 1 (PD-1) with programmed cell death ligand PD-L activates the immune checkpoint leading to T-cell dysfunction, exhaustion, and tolerance, especially in Hodgkin lymphoma (HL) where the PD-L/ Janus kinase (Jak) signaling was frequently found altered. Anti-PD-1 or anti-PD-L1 monoclonal antibodies can reverse this immune checkpoint, releasing the brake on T-cell responses. The characterization of the mechanisms regulating both the expression of PD-1 and PD-L and their function(s) in HL is ongoing. We provide in this review the recent findings focused on this aim with special attention on the major research topics, such as adverse events and resistance to PD-1–PD-L1 inhibitor treatment, together with a part about angiogenesis, extracellular vesicles, and microbiome in HL pathogenesis.
