Abstract
ADAMTS8 (A Disintegrin-like and Metalloproteinase with Thrombospondin motifs 8) is a secreted zinc-dependent metalloproteinase whose expression is downregulated in a variety of solid tumors. Xenografts expressing high levels of ADAMTS8 have a poor capacity to invade and migrate in nude mice. While this data highlights a beneficial, anti-cancerogenic role of ADAMTS8, the mechanism behind this activity is still not fully elucidated. So far, the only reported substrate for ADAMTS8 is osteopontin (OPN), an extracellular matrix protein widely implicated in multiple steps of cancer progression, albeit, similar to other ADAMTS family members, it is very likely that ADAMTS8 cleaves a variety of substrates. The availability of purified ADAMTS8 may enlighten the biological role of this metalloproteinase.Here we describe methods for expression and purification of recombinant ADAMTS8 in HEK293T cells as well as a convenient assay to test ADAMTS8 proteolytic activity using OPN as a substrate.

Abstract
Clear cell renal carcinoma (ccRCC) is one of the cancers that posed a severe threat to human life on a global scale. The ADAMTS family has been proven to be involved in a number of tumor types, although it is yet unknown how they relate to ccRCC. The mRNA expression matrix and other clinically relevant information of 607 ccRCC were sourced from TCGA database. The role of ADAMTS family genes in ccRCC was determined by differential gene expression analysis and gene set enrichment analysis (GSEA). Employing stage grading, gene mutation, and survival analysis, the genes most linked to the prognosis of ccRCC were identified. The influence of genes on the pathway was determined by Kyoto Encyclopedia of Genes and Genes (KEGG) analysis. Following that, the gene's impact on ccRCC was verified by qRT-PCR, WB, MTT, Transwell detection, and a wound healing assay. Bioinformatics analysis showed that ADAMTS10 was overexpressed in cancerous tissues of people with ccRCC and its expression increased with tumor grade. Mutation analysis showed that the main cause of mutation in the ADAMTS family gene was amplification. The prognosis and survival of the ADAMTS10 elevated expression group were lower than those of the poorly expressed group, as demonstrated by a survival analysis. On the basis of the findings of MRI, we examined 60 clinical patients and collected their cancer along with the surrounding tissues. The results of qPCR detection showed that the expression of ADAMTS10 was considerably higher in cancerous regions of 60 clinical users than it was in the tissues nearby. Inhibiting ADAMTS10 development prevents cancer cells from proliferating, invading, and migrating. The KEGG analysis links ADAMTS10 to the NF-κB signal pathway. WB experiment confirmed that inhibiting ADAMTS10 expression can inhibit the activation of the NF-κB signal pathway. ADAMTS10 may be a promising prognostic marker for ccRCC that can be employed independently.

Abstract
A disintegrin-like and metalloprotease with therombospondin type1 motif 8 (ADAMTS8) plays an important role in many malignancies. However, the clinical and biological significance of ADAMTS8 in breast cancer remain unknown. In this study, the clinical data from 1066 breast cancer patients were analyzed by The Cancer Genome Atlas (TCGA) database, and were analyzed using the correlation between ADAMTS8 expression and the clinicopathological features and prognoses. The CCK-8 assay, clone formation assay, flow cytometry and Transwell assay were used to characterize the effects of ADAMTS8 on proliferation, migration and invasion of breast cancer cells. Gene set enrichment analysis (GSEA) and western blotting were used to identify the potential molecular mechanism on how ADAMTS8 exert its biological function. ADAMTS8 overexpression correlated longer overall survival (OS) and progression-free survival (PFS). ADAMTS8 was considered as an independent prognostic factor for OS. ADAMTS8 overexpression inhibited breast cancer cell proliferation, migration and invasion in vitro, and induced G2/M cell cycle arrest. ADAMTS8 was also involved in cell cycle regulation and was associated with the EGFR/Akt signaling pathway. ADAMTS8 knockdown showed the reverse effect. Together, the results showed that ADAMTS8 functioned as a tumor suppressor gene (TGS) and could be a prognostic biomarker for breast cancer.

Abstract
Yixin granules are medications modified from a Chinese prescription (Sheng Xian Tang) that has been used to alleviate shortness of breath. ADAM metallopeptidase with thrombospondin type 1 motif 8 (ADAMTS8) is upregulated in the myocardium of patients with dilated cardiomyopathy. Its high expression is associated with tumor necrosis factor (TNF) -α and myocardial fibrosis. This study aimed to explore the effect of Yixin granules on heart failure (HF) in rats and whether this effect is correlated with ADAMTS8 to provide new ideas for the treatment of HF.HF rat models were established by ligation of the left anterior descending coronary artery. Model rats were injected with adeno-associated virus vectors for the overexpression of ADAMTS8 and/or treated with Yixin granules for 4 weeks. Hematoxylin-eosin and Masson staining were used to detect myocardial injury and fibrosis, respectively. Reverse transcription polymerase chain reaction, western blotting, and/or enzyme-linked immunosorbent assay were used to detect the expression of ADAMTS8, TNF-α, interleukin (IL) -1β, IL-6, collagen I, collagen III, and α-smooth muscle actin in myocardium. The myocardial infarction area of rats was measured using 2,3,5-triphenyltetrazolium chloride staining.ADAMTS8 was upregulated in the myocardium of HF rats. Yixin granule treatment improved left ventricular contractility and reduced ADAMTS8 expression, myocardial injury, inflammation, and fibrosis in HF rats. ADAMTS8 overexpression aggravated myocardial injury, inflammation, and fibrosis. Moreover, ADAMTS8 overexpression counteracted the cardioprotective effects of Yixin granules.Yixin granules may reduce myocardial inflammation and fibrosis in HF rats by inhibiting the expression of ADAMTS8.

The Therapeutic Potential of ADAMTS8 in Lung Adenocarcinoma without Targetable Therapy. J Pers Med 2022; 12:jpm12060902.

Abstract
Lung cancer is well known for its high mortality worldwide. The treatment for advanced lung cancer needs more attention to improve its survival time. A disintegrin and metallopeptidase with thrombospondin motifs 8 (ADAMTS8) has been linked to several cancer types. However, its role in lung cancer is worthy of deep investigation to promote novel drug development. This study took advantage of RNA-seq and bioinformatics to verify the role that ADAMTS8 plays in lung cancer. The functional assays suggested that ADAMTS8 mediates invasion and metastasis when expressed at a low level, contributing to poor overall survival (OS). The expression of ADAMTS8 was under the regulation of GATA Binding Protein 1 (GATA1) and executed its pathologic role through Thrombospondin Type 1 Domain Containing 1 (THSD1) and ADAMTS Like 2 (ADAMTSL2). To define the impact of ADAMTS8 in the lung cancer treatment strategy, this study further grouped lung cancer patients in the TCGA database into mutated epidermal growth factor receptor (EGFR)/wild-type EGFR and programmed death ligand 1 (PD-L1) high/low groups. Importantly, the expression of ADAMTS8 was correlated positively with the recruitment of anticancer NKT cells and negatively with the infiltration of immunosuppressive Treg and exhausted T cells. The results indicated that lung cancer patients with higher ADAMTS8 levels among wild-type EGFR or low PD-L1 groups survive longer than those with lower levels do. This study indicates that ADAMTS8 might be a treatment option for patients with lung adenocarcinoma who lack efficient targeted or immunotherapies.

Abstract
Background: Lung adenocarcinoma (LUAD) accounts for the majority of lung cancers, and the survival of patients with advanced LUAD is poor. The extracellular matrix (ECM) is a fundamental component of the tumor microenvironment (TME) that determines the oncogenesis and antitumor immunity of solid tumors. However, the prognostic value of extracellular matrix-related genes (ERGs) in LUAD remains unexplored. Therefore, this study is aimed to explore the prognostic value of ERGs in LUAD and establish a classification system to predict the survival of patients with LUAD.Methods: LUAD samples from The Cancer Genome Atlas (TCGA) and GSE37745 were used as discovery and validation cohorts, respectively. Prognostic ERGs were identified by univariate Cox analysis and used to construct a prognostic signature by Least Absolute Shrinkage and Selection Operator (LASSO) regression analysis. The extracellular matrix-related score (ECMRS) of each patient was calculated according to the prognostic signature and used to classify patients into high- and low-risk groups. The prognostic performance of the signature was evaluated using Kaplan–Meier curves, Cox regression analyses, and ROC curves. The relationship between ECMRS and tumor immunity was determined using stepwise analyses. A nomogram based on the signature was established for the convenience of use in the clinical practice. The prognostic genes were validated in multiple databases and clinical specimens by qRT-PCR.Results: A prognostic signature based on eight ERGs (FERMT1, CTSV, CPS1, ENTPD2, SERPINB5, ITGA8, ADAMTS8, and LYPD3) was constructed. Patients with higher ECMRS had poorer survival, lower immune scores, and higher tumor purity in both the discovery and validation cohorts. The predictive power of the signature was independent of the clinicopathological parameters, and the nomogram could also predict survival precisely.Conclusions: We constructed an ECM-related gene signature which can be used to predict survival and tumor immunity in patients with LUAD. This signature can serve as a novel prognostic indicator and therapeutic target in LUAD.

Altered gene expression of selected matrix metalloproteinase system proteins in the broiler chicken gastrointestinal tract during post-hatch development and coccidia infection*. Poult Sci 2022; 101:101915. [PMID: 35687960 PMCID: PMC9190011 DOI: 10.1016/j.psj.2022.101915] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Track Full Text] [Download PDF] [Figures] [Journal Information] [Subscribe] [Scholar Register] [Received: 12/21/2021] [Revised: 03/31/2022] [Accepted: 03/31/2022] [Indexed: 11/20/2022] Open
Abstract
Matrix metalloproteinases (MMPs) are a family of proteases, that can process extracellular matrix (ECM) components and non-ECM molecules. MMPs can also function intracellularly in proteolytic and nonproteolytic functions. The participation of MMPs in the remodeling of the chicken gastrointestinal tract is largely unknown. The aim of the present study was to examine 1) the early neonatal developmental changes and effect of delayed access to feed immediately post-hatch (PH) and 2) the effect of Eimeria infection on mRNA expression of selected MMPs, their tissue inhibitors (TIMPs), and a disintegrin and metalloproteinase (ADAM) metallopeptidase with thrombospondin type 1 motif 8 (ADAMTS8) in the gastrointestinal tract of chicken. Protein localization of MMPs and TIMPs was also carried out in the normal ileal wall at −48, 24, and 336 h relative to hatch using immunofluorescence. In experiment 1, newly hatched Ross 708 chicks received feed and water immediately PH or were subjected to 48 h delayed access to feed. Chickens were sampled at −48, 0, 4, 24, 48, 72, 96, 144, 192, 240, 288, and 336 h PH. Ileum was collected for investigation of gene expression or fixed in paraformaldehyde for immunofluorescence. In experiments 2 and 3, Ross 708 male broilers were infected, at 21 d of age with Eimeria maxima or E. acervulina or sham-infected with water. Intestinal tissues were collected at 7 and 10 d postinfection for gene expression analysis. In general, mRNA expression patterns of all examined genes showed downregulation during the first 2 wk PH and were not affected by delay in feed access. These development-dependent changes in expression and tissue-dependent localization in the ileum of selected MMPs and TIMPs indicate that these molecules participate in the remodeling of chicken intestinal tissues during PH development. Increased expression of MMP-7 and MMP-9 transcripts in the intestine of Eimeria infected birds suggests an important role for these enzymes in the process of tissue remodeling and destruction in pathological conditions. The findings of this study are important for understanding the relationship between the expression of the MMP system and intestinal development, as well its role in gastrointestinal infection and subsequent recovery.

Abstract
Purpose Invasive breast carcinoma (BC) is the most common malignant breast tumor. Most lymph node-negative (LN-) early-stage BC patients usually have a good prognosis, but 7% of patients still develop metastasis after surgery. It is not yet clear how to screen candidates with poorer prognosis in LN- early-stage patients, so that they can receive intensive therapy. Hence, we expect to identify a prognostic biomarker to assess postoperative metastasis in LN- early-stage BC patients. Patients and Methods Screening and verifying of candidate genes by gene expression profiling of LN- early-stage BC samples (n = 640) from 3 independent public datasets. Univariable and multivariable Cox regression analyses showed the relation between the candidate genes and postoperative metastasis. Distant metastasis-free survival (DMFS) analysis was performed to examine the prognostic significance. Quantitative real-time polymerase chain reaction (qRT-PCR) assays were performed to examine ADAMTS8 expression and prognostic association in our clinical samples (n = 25). Results In the discovery cohort (TCGA and GSE20685 datasets), we found that ADAMTS8 tend to be low expression in LN- early-stage BC, and low ADAMTS8 expression was associated with postoperative metastasis and shortened DMFS. Moreover, the above finding was confirmed in the validation cohort (GSE6538 dataset). Lower ADAMTS8 expression was related to poorer prognostic clinical stage and PAM50 subtypes and shorter DMFS. Gene enrichment analysis indicated that ADAMTS8 may be correlated with BC metastasis. qRT-PCR assays of our clinical tumor sample showed that patients with low ADAMTS8 expression seem to be prone to developing metastasis and have a shorter DMFS time. Conclusion Our research shows that low ADAMTS8 expression is associated with postoperative metastasis and shortened DMFS in LN- early-stage BC patients, which suggests that ADAMTS8 may be a potential prognostic marker for postoperative metastasis in LN- early-stage BC patients.

Abstract
Background A disintegrin-like and metalloproteinase domain with thrombospondin type 1 motifs (ADAMTS)-like proteins, including ADAMTSL1-6 and papilin, which are part of the mammalian ADAMTS superfamily, appear to be relevant to extracellular matrix function and the regulation of ADAMTS protease activity. Their roles in tumor initiation and progression and regulating the tumor microenvironment (TME) are now recognized. Methods In the present study, a comprehensive investigation of the pan-cancer effects of ADAMTSLs and their associations with patient survival, drug responses, and the TME was performed by integrating The Cancer Genome Atlas (TCGA) data and annotated data resources. Results The expression of ADAMTSL family members was found to be dysregulated in many cancer types. More importantly, their expression was frequently associated with patients’ overall survival (OS), drug responses, and the TME. ADAMTSL1, ADAMTSL4, and ADAMTSL5 were primarily associated with aggressive phenotypes, while PAPLN was more frequently associated with a favorable prognosis. In a non-small cell lung cancer (NSCLC) cohort, Thrombospondin Type 1 Domain Containing 4 (THSD4) (ADAMTSL6) and Papilin (PAPLN) were associated with immune checkpoint inhibitor (ICI) sensitivity in samples from the Gene Expression Omnibus repository (GSE135222). Twenty and 30 proteins related to THSD4 and PAPLN, respectively, were identified through a proteomic analysis of 18 Chinese lung adenocarcinoma patients. Conclusions Our findings extend understandings of the role of the ADAMTSL family in cancers and are a valuable resource on their clinical utility. This article provides insight into the clinical importance of next-generation sequencing technology to identify novel biomarkers for prognosis and investigate therapeutic strategy for clinical benefit.

Abstract
A disintegrin-like and metalloprotease domain with thrombospondin type 1 motifs (ADAMTS)8 is a secreted protease, which was recently implicated in pathogenesis of pulmonary arterial hypertension (PAH). However, the substrate repertoire of ADAMTS8 and regulation of its activity are incompletely understood. Although considered a proteoglycanase because of high sequence similarity and close phylogenetic relationship to the proteoglycan-degrading proteases ADAMTS1, 4, 5, and 15, as well as tight genetic linkage with ADAMTS15 on human chromosome 11, its aggrecanase activity was reportedly weak. Several post-translational factors are known to regulate ADAMTS proteases such as autolysis, inhibition by endogenous inhibitors, and receptor-mediated endocytosis, but their impacts on ADAMTS8 are unknown. Here, we show that ADAMTS8 undergoes autolysis at six different sites within its spacer domain. We also found that in contrast to ADAMTS4 and 5, ADAMTS8 levels were not regulated through low-density lipoprotein receptor-related protein 1 (LRP1)-mediated endocytosis. Additionally, ADAMTS8 lacked significant activity against the proteoglycans aggrecan, versican, and biglycan. Instead, we found that ADAMTS8 cleaved osteopontin, a phosphoprotein whose expression is upregulated in PAH. Multiple ADAMTS8 cleavage sites were identified using liquid chromatography–tandem mass spectrometry. Osteopontin cleavage by ADAMTS8 was efficiently inhibited by TIMP-3, an endogenous inhibitor of ADAMTS1, 4, and 5, as well as by TIMP-2, which has no previously reported inhibitory activity against other ADAMTS proteases. These differences in post-translational regulation and substrate repertoire differentiate ADAMTS8 from other family members and may help to elucidate its role in PAH.

Abstract
Lung cancer is a malignancy with high mortality worldwide, and metastasis occurs at a high frequency even when cancer spread is not detectable at primary operation. Cancer stemness plays an important role in malignant cancer behavior, treatment resistance, and cancer metastasis. Therefore, understanding the molecular pathogenesis behind cancer-stemness-mediated metastasis and developing effective approaches to prevent metastasis are key issues for improving cancer treatment. In this study, we investigated the role of CD44 stemness marker in lung cancer using in vitro and clinical studies. Immunohistochemical staining of lung cancer tissue specimens revealed that primary tumors with higher CD44 expression showed increased metastasis to regional lymph nodes. Flow cytometry analysis suggested that CD44 positive cells were enriched in the metastatic lymph nodes compared to the primary tumors. CD44 overexpression significantly increased migration and invasion abilities of lung cancer cells through CD44-induced ERK phosphorylation, ZEB1 upregulation, and Claudin-1 downregulation. Furthermore, ERK inhibition suppressed the migration and invasion abilities of CD44-overexpressing lung cancer cells. In summary, our in vitro and clinical results indicate that CD44 may be a potential prognostic and therapeutic marker for lung cancer patients.

Abstract
Simple Summary Members of the adamalysin family are multi-domain proteins involved in many cancer-related functions. In this review, we will examine the literature on the involvement of adamalysins in hepatocellular carcinoma progression and their importance in the tumor microenvironment where they regulate the inflammatory response and the epithelial–mesenchymal transition. We complete this review with an analysis of adamalysin expression in a large cohort of patients with hepatocellular carcinoma from The Cancer Genome Atlas (TCGA) database. These original results give a new insight into the involvement of all adamalysins in the primary liver cancer. Abstract The tumor microenvironment plays a major role in tumor growth, invasion and resistance to chemotherapy, however understanding how all actors from microenvironment interact together remains a complex issue. The tumor microenvironment is classically represented as three closely connected components including the stromal cells such as immune cells, fibroblasts, adipocytes and endothelial cells, the extracellular matrix (ECM) and the cytokine/growth factors. Within this space, proteins of the adamalysin family (ADAM for a disintegrin and metalloproteinase; ADAMTS for ADAM with thrombospondin motifs; ADAMTSL for ADAMTS-like) play critical roles by modulating cell–cell and cell–ECM communication. During last decade, the implication of adamalysins in the development of hepatocellular carcinoma (HCC) has been supported by numerous studies however the functional characterization of most of them remain unsettled. In the present review we propose both an overview of the literature and a meta-analysis of adamalysins expression in HCC using data generated by The Cancer Genome Atlas (TCGA) Research Network.

Abstract
A disintegrin and metallopeptidase with thrombospondin motifs (ADAMTSs), which is frequently dysregulated in cancers and is involved in carcinogenesis and cancer progression. The present study identified that ADAMTS8 expression is downregulated in esophageal squamous cell carcinoma (ESCC) tissues when compared with nontumor tissue. The expression of ADAMTS8 is closely associated with clinical stage and lymph node metastasis in patients with ESCC. Furthermore, functional studies have shown that ADAMTS8 overexpression could reduce abilities of proliferation, migration, and invasion and promote apoptosis of ESCC cells. Meanwhile, monocyte chemotactic protein-1 and interleukin-6 are markedly deregulated by ADAMTS8 overexpression. Consistently, in vivo data showed that ADAMTS8 overexpression led to a reduction in tumor growth. These results indicate that altering ADAMTS8 expression could modify the outcomes of ESCC by inhibiting cell proliferation and invasion, while promoting the apoptosis of ECSS cells. Thus, ADAMTS8 represents a potential therapeutic target for ESCC therapy.

Abstract
Introduction A disintegrin and metallopeptidase with thrombospondin motifs (ADAMTSs), whose expression is dysregulated in various cancers, is implicated in cancer development. Herein, we aimed to investigate the functional role of ADAMTS8 in breast cancer (BC) and explore the underlying mechanisms. Methods The protein expression of ADAMTS8 in BC cell lines and tumor tissues from BC patients was quantified by Western blot. ADAMTS8 overexpression was induced by transfection with pEZ-M90-ADAMTS8 plasmid using lipofectamine 2000. To generate ADAMTS8 stable knockdown cells, MDA-MB-231 cells were transfected with psi-H1-ADAMTS8siRNA plasmids. Cell counting kit-8 (CCK-8) assay, wound-healing assay, transwell assay and flow cytometry assay were employed to analyze the effects of ADAMTS8 on the proliferation, migration, invasion and apoptosis of BC cells. Chemosensitivity also was assessed using CCK-8 assay. The expressions of β-catenin, MMP-7 and c-Myc were measured by Western blot. Results Our results showed that ADAMTS8 expression was significantly lower in BC tissues than that in adjacent non-tumor tissues. Overexpression of ADAMTS8 in MDA-MB-453 cells could inhibit the cell proliferation, migration and invasion and promote apoptosis. ADAMTS8 knockdown displayed the reverse effect in MDA-MB-231 cells. Consistently, in vivo data showed that ADAMTS8 overexpression led to a reduction in tumor growth. In addition, chemosensitivity testing in MDA-MB-453 cells transfected with pEZ-M90-ADAMTS8 plasmid indicated that cisplatin inhibited cell growth dramatically. Furthermore, attenuated β-catenin, MMP-7 and c-Myc level was detected after ADAMTS8 overexpression. Conclusion These results indicate that increased ADAMTS8 expression could modify the progression of BC by inhibiting cell proliferation and invasion while promoting the apoptosis of BC cells. Thus, ADAMTS8 represents a potential therapeutic target for BC therapy.

Abstract
Despite the use of immune checkpoint blockade (ICB) therapy for hepatocellular carcinoma (HCC), developing more effective immunotherapy and predicting HCC's response to ICB therapy remain top priorities. Ribosomal protein S3A (RPS3A) is a multifunctional molecule, but its association with tumor immune cell infiltration and prognosis in HCC patients is unknown. Thus, we aimed to investigate the correlation of RPS3A with HCC immune cell infiltration and prognosis to explore novel therapeutic strategies and prognostic biomarkers for this disease. Here, we showed that RPS3A expression levels were higher in HCC cell lines and samples than in normal hepatocytes and adjacent tumor-free tissues, respectively, and patients with high RPS3A expression had worse overall and recurrence-free survival durations than did patients with low expression. Moreover, single-sample gene set enrichment analysis (ssGSEA) and immunohistochemistry demonstrated a strongly negative correlation between RPS3A expression and tumor immune cell infiltration. Meanwhile, RPS3A was revealed to be positively correlated with that of most examined immune checkpoint molecules. GSEA also suggested that high RPS3A expression promoted the biological processes related to tumorigenesis, metastasis, and immunosuppression. Finally, RPS3A-based nomograms were constructed and exhibited better predictive accuracy for HCC prognosis and more net clinical benefits when compared with traditional prognosis-prediction staging systems. In short, these findings suggest that high RPS3A expression correlates with low tumor immune cell infiltration and poor prognosis in HCC patients. Furthermore, RPS3A-based nomograms are robust HCC prognostic predictors. RPS3A therefore may serve as a therapeutic target in and predict the efficacy of ICB therapy for HCC.

Abstract
The “A Disintegrin and Metalloproteinase with Thrombospondin Motif” (ADAMTS) family of genes is involved in the occurrence and development of different cancers. However, the prognostic value of these genes in gastric cancer (GC) has not been revealed. The present study was thus conducted to determine the prognostic value for the ADAMTS family of genes in GC. First, we evaluated the mRNA expression levels of the ADAMTS family in GC patients using a GEPIA dataset. Thereafter, we determined the prognostic value of these genes by analyzing their mRNA level using the Kaplan–Meier Plotter database. The mRNA expression level of ADAMTS12 was randomly validated by qRT-PCR and meta-analysis while its coexpression genes were derived using Coexpedia. Finally, we performed Gene Ontology (GO) annotation and Kyoto Encyclopedia of Genes and Genomes (KEGG) pathway enrichment analyses using the OmicShare Tools. Compared to normal tissues, expression of ADAMTS2 and 12 was significantly higher while that of ADAMTS1, 13, and 15 was significantly lower in GC tissues. According to the RNA-seq and gene chip data, the ADAMTS family (6, 7, 12, 15, and 18) of genes was closely related to the prognosis of GC, and their high expression levels were associated with poor prognosis and survival time. In addition, ADAMTS12 was highly expressed in 20 pairs of GC tissues based on RT-PCR (P=0.016) and meta-analysis (SMD: 0.73, 95% CI: 0.32–1.14, P < 0.001). GO and KEGG pathway analyses indicated that the ADAMTS12 coexpressed genes were enriched in the pathways of extracellular matrix organization, extracellular matrix structural constituent, extracellular matrix, and protein digestion and absorption. Herein, we discovered the prognostic values and biological roles of the ADAMTS genes in GC.

Abstract
An increasing body of evidence supports the association of immune genes with tumorigenesis and prognosis of breast cancer (BC). This research aims at exploring potential regulatory mechanisms and identifying immunogenic prognostic markers for BC, which were used to construct a prognostic signature for disease-free survival (DFS) of BC based on artificial intelligence algorithms. Differentially expressed immune genes were identified between normal tissues and tumor tissues. Univariate Cox regression identified potential prognostic immune genes. Thirty-four transcription factors and 34 immune genes were used to develop an immune regulatory network. The artificial intelligence survival prediction system was developed based on three artificial intelligence algorithms. Multivariate Cox analyses determined 17 immune genes (ADAMTS8, IFNG, XG, APOA5, SIAH2, C2CD2, STAR, CAMP, CDH19, NTSR1, PCDHA1, AMELX, FREM1, CLEC10A, CD1B, CD6, and LTA) as prognostic biomarkers for BC. A prognostic nomogram was constructed on these prognostic genes. Concordance indexes were 0.782, 0.734, and 0.735 for 1-, 3-, and 5- year DFS. The DFS in high-risk group was significantly worse than that in low-risk group. Artificial intelligence survival prediction system provided three individual mortality risk predictive curves based on three artificial intelligence algorithms. In conclusion, comprehensive bioinformatics identified 17 immune genes as potential prognostic biomarkers, which might be potential candidates of immunotherapy targets in BC patients. The current study depicted regulatory network between transcription factors and immune genes, which was helpful to deepen the understanding of immune regulatory mechanisms for BC cancer. Two artificial intelligence survival predictive systems are available at https://zhangzhiqiao7.shinyapps.io/Smart_Cancer_Survival_Predictive_System_16_BC_C1005/ and https://zhangzhiqiao8.shinyapps.io/Gene_Survival_Subgroup_Analysis_16_BC_C1005/. These novel artificial intelligence survival predictive systems will be helpful to improve individualized treatment decision-making.

Abstract
Background Lung adenocarcinoma (LUAD) is the major subtype of lung cancer and the most lethal malignant disease worldwide. However, the molecular mechanisms underlying LUAD are not fully understood. Methods Four datasets (GSE118370, GSE85841, GSE43458 and GSE32863) were obtained from the gene expression omnibus (GEO). Identification of differentially expressed genes (DEGs) and functional enrichment analysis were performed using the limma and clusterProfiler packages, respectively. A protein–protein interaction (PPI) network was constructed via Search Tool for the Retrieval of Interacting Genes (STRING) database, and the module analysis was performed by Cytoscape. Then, overall survival analysis was performed using the Kaplan–Meier curve, and prognostic candidate biomarkers were further analyzed using the Oncomine database. Results Totally, 349 DEGs were identified, including 275 downregulated and 74 upregulated genes which were significantly enriched in the biological process of extracellular structure organization, leukocyte migration and response to peptide. The mainly enriched pathways were complement and coagulation cascades, malaria and prion diseases. By extracting key modules from the PPI network, 11 hub genes were screened out. Survival analysis showed that except VSIG4, other hub genes may be involved in the development of LUAD, in which MYH10, METTL7A, FCER1G and TMOD1 have not been reported previously to correlated with LUAD. Briefly, novel hub genes identified in this study will help to deepen our understanding of the molecular mechanisms of LUAD carcinogenesis and progression, and to discover candidate targets for early detection and treatment of LUAD.
