Abstract
Uveal melanoma (UVM) remains the leading intraocular malignancy in adults, with a poor prognosis for those with metastatic disease. Tryptophan metabolism plays a pivotal role in influencing cancerous properties and modifying the tumor's immune microenvironment. In this study, we explore the relationship between tryptophan metabolism-related gene (TRMG) expression and the various features of UVM, including prognosis and tumor microenvironment. Our analysis included 143 patient samples sourced from public databases. Using K-means clustering, we categorized UVM patients into two distinct clusters. Further, we developed a prognostic model based on five essential genes, effectively distinguishing between low-risk and high-risk patients. This distinction underscores the importance of TRMGs in UVM prognostication. Combining TRMG data with gender to create nomograms demonstrated exceptional accuracy in predicting UVM patient outcomes. Moreover, our analysis reveals correlations between risk assessments and immune cell infiltrations. Notably, the low-risk group displayed a heightened potential response to immune checkpoint inhibitors. In conclusion, our findings underscore the dynamic relationship between TRMG expression and various UVM characteristics, presenting a novel prognostic framework centered on TRMGs. The deep connection between TRMGs and UVM's tumor immune microenvironment emphasizes the crucial role of tryptophan metabolism in shaping the immune landscape. Such understanding paves the way for designing targeted immunotherapy strategies for UVM patients.

Abstract
Cancer is a major threat to human health today. Although the existing anticancer treatments have effectively improved the prognosis of some patients, there are still other patients who cannot benefit from these well-established strategies. Reprogramming of lipid metabolism is one of the typical features of cancers. Recent studies have revealed that key enzymes involved in lipid metabolism may be effective anticancer therapeutic targets, but the development of therapeutic lipid metabolism targets is still insufficient. ECHS1 (enoyl-CoA hydratase, short chain 1) is a key enzyme mediating the hydration process of mitochondrial fatty acid β-oxidation and has been observed to be abnormally expressed in a variety of cancers. Therefore, with ECHS1 and cancer as the main keywords, we searched the relevant studies of ECHS1 in the field of cancer in Pubmed, summarized the research status and functions of ECHS1 in different cancer contexts, and explored its potential regulatory mechanisms, with a view to finding new therapeutic targets for anti-metabolic therapy. By reviewing and summarizing the retrieved literatures, we found that ECHS1 regulates malignant biological behaviors such as cell proliferation, metastasis, apoptosis, autophagy, and drug resistance by remodeling lipid metabolism and regulating intercellular oncogenic signaling pathways. Not only that, ECHS1 exhibits early diagnostic and prognostic value in clear cell renal cell carcinoma, and small-molecule inhibitors that regulate ECHS1 also show therapeutic significance in preclinical studies. Taken together, we propose that ECHS1 has the potential to serve as a therapeutic target of lipid metabolism.

Ectosomal PKM2 Promotes HCC by Inducing Macrophage Differentiation and Remodeling the Tumor Microenvironment. Mol Cell 2020; 78:1192-1206.e10.

Abstract
Tumor-derived extracellular vesicles are important mediators of cell-to-cell communication during tumorigenesis. Here, we demonstrated that hepatocellular carcinoma (HCC)-derived ectosomes remodel the tumor microenvironment to facilitate HCC progression in an ectosomal PKM2-dependent manner. HCC-derived ectosomal PKM2 induced not only metabolic reprogramming in monocytes but also STAT3 phosphorylation in the nucleus to upregulate differentiation-associated transcription factors, leading to monocyte-to-macrophage differentiation and tumor microenvironment remodeling. In HCC cells, sumoylation of PKM2 induced its plasma membrane targeting and subsequent ectosomal excretion via interactions with ARRDC1. The PKM2-ARRDC1 association in HCC was reinforced by macrophage-secreted cytokines/chemokines in a CCL1-CCR8 axis-dependent manner, further facilitating PKM2 excretion from HCC cells to form a feedforward regulatory loop for tumorigenesis. In the clinic, ectosomal PKM2 was clearly detected in the plasma of HCC patients. This study highlights a mechanism by which ectosomal PKM2 remodels the tumor microenvironment and reveals ectosomal PKM2 as a potential diagnostic marker for HCC.

Abstract
The current research aimed to explore the impact of (-)-hydroxycitric acid (HCA) on fat metabolism and investigate whether this action of (-)-HCA was associated with modulation of glucose-6-phosphote isomerase (GPI) expression in chicken embryos. We constructed a recombinant plasmid (sh2-GPI) to inhibit GPI expression, and then embryos were treated with (-)-HCA. Results showed that (-)-HCA reduced lipid droplet accumulation, triglyceride content, and lipogenesis factors mRNA level and increased lipolysis factors mRNA expression, while this effect caused by (-)-HCA was markedly reversed when the chicken embryos were pretreated with sh2-GPI. (-)-HCA increased phospho (p)-acetyl-CoA carboxylase, enoyl-CoA hydratase short chain-1, carnitine palmitoyl transferase 1A, p-AMP-activated protein kinase, and peroxisome proliferators-activated receptor α protein expression, and this action of (-)-HCA also dispelled when the chicken embryos were pretreated with sh2-GPI. These data demonstrated that (-)-HCA decreased fat deposition via activation of the AMPK pathway, and the fat-reduction action of (-)-HCA was due to the increasing of GPI expression in chicken embryos.

Abstract
The human ECHS1 gene encodes the short-chain enoyl coenzyme A hydratase, the enzyme that catalyzes the second step of β-oxidation of fatty acids in the mitochondrial matrix. We report on a boy with ECHS1 deficiency who was diagnosed with Leigh syndrome at 21 months of age. The patient presented with hypotonia, metabolic acidosis, and developmental delay. A combined respiratory chain deficiency was also observed. Targeted exome sequencing of 776 mitochondria-associated genes encoded by nuclear DNA identified compound heterozygous mutations in ECHS1. ECHS1 protein expression was severely depleted in the patient's skeletal muscle and patient-derived myoblasts; a marked decrease in enzyme activity was also evident in patient-derived myoblasts. Immortalized patient-derived myoblasts that expressed exogenous wild-type ECHS1 exhibited the recovery of the ECHS1 activity, indicating that the gene defect was pathogenic. Mitochondrial respiratory complex activity was also mostly restored in these cells, suggesting that there was an unidentified link between deficiency of ECHS1 and respiratory chain. Here, we describe the patient with ECHS1 deficiency; these findings will advance our understanding not only the pathology of mitochondrial fatty acid β-oxidation disorders, but also the regulation of mitochondrial metabolism.

Abstract
AIMS AND BACKGROUND Hepatocellular carcinoma (HCC) is a dismal malignancy associated with multiple molecular changes. The purpose of this study was to identify the differentially expressed genes and analyze the biological processes related to HCC. METHODS AND STUDY DESIGN Datasets of HCC were obtained from the NCBI Gene Expression Omnibus. Integrated analysis of differentially expressed genes was performed using the INMEX program. Then Gene Ontology enrichment analyses and pathway analysis were performed based on the Gene Ontology website and Kyoto Encyclopedia of Genes and Genomes. A protein-protein interaction network was constructed using the Cytoscape software; the netwerk served to find hub genes for HCC. Real-time RT-PCR was used to validate the microarray data for hub genes. RESULTS We identified 273 genes that were differentially expressed in HCC. Gene Ontology enrichment analyses revealed response to cadmium ion, cellular response to cadmium ion, and cellular response to zinc ion for these genes. Pathway analysis showed that significant pathways included fatty acid metabolism, butanoate metabolism, and PPAR signaling pathway. The protein-protein interaction network indicated that CDH1, ECHS1, ACAA1, MT2A, and MYC were important genes which participated in many interactions. Experimental validation of the role of four upregulated genes (ECHS1, ACAA1, MT2A and MYC) in the progression of HCC was carried out. CONCLUSIONS Our study displayed genes that were consistently differentially expressed in HCC. The biological pathways and protein-protein interaction networks associated with those genes were also identified. We predicted that CDH1, ECHS1, ACAA1, MT2A, and MYC might be target genes for diagnosing HCC.

Abstract
Colorectal cancer is one of the most commonly diagnosed types of cancer and is a leading cause of cancer-associated mortality worldwide. Short chain enoyl coenzyme A hydratase 1 (ECHS1) is an important gene involved in the mitochondrial fatty acid β-oxidation pathway. In addition, ECHS1 has been implicated in a variety of cancers, including breast, prostate, colon and liver cancer. The aim of the present study was to examine the expression of ECHS1 in the human HCT-8 colorectal cancer cell line. The results showed that ECHS1 expression was significantly increased in poorly-differentiated cells compared with that in well-differentiated cells. In order to further investigate the functions of ECHS1 in colorectal cancer cells, a stably transfected HCT-8 cell line expressing small interfering (si)RNA targeting the ECHS1 gene was established. The expression of the ECHS1 siRNA was found to reduce ECHS1 protein levels in ECHS1-silenced cells by >40%. Cell proliferation and cell migration of the siECHS1 cells were characterized using Cell Counting Kit-8 and Transwell assays, respectively, the results of which showed that the constitutive knockdown of the ECSH1 gene in HCT-8 cells significantly inhibited cell proliferation and migration. Furthermore, decreased levels of Akt and glycogen synthase kinase (GSK)3β phosphorylation were observed in ECHS1-silenced HCT-8 cells compared with that of parental or pU6 empty vector-transfected cells. In conclusion, the results of the present study suggested that ECHS1 may have an important role in colorectal cancer cell proliferation and migration via activation of Akt- and GSK3β-associated signaling pathways.

Abstract
Enoyl coenzyme A hydratase short chain 1 (ECHS1) is an important part of the mitochondrial fatty acid β-oxidation pathway. Altered ECHS1 expression has been implicated in cancer cell proliferation. This study assessed ECHS1 expression in human gastric cancer cell lines and investigated the effects of ECHS1 knockdown on gastric cancer cell proliferation and migration. The human gastric cancer cell lines SGC-7901, BGC-823 and MKN-28, and the immortalized human gastric epithelial mucosa GES-1 cell line were analyzed for ECHS1 protein levels using western blot. The effectiveness of ECHS1-RNA interference was also determined using western blot. Proliferation and migration of the siECHS1 cells were respectively measured with the CCK-8 and transwell assays. Phosphorylation of PKB and GSK3β was assessed using western blot. ECHS1 protein levels were significantly higher in poorly differentiated cells than in well-differentiated cells and immortalized gastric epithelial mucosa cells. Stable expression of ECHS1 shRNA was associated with an over 41% reduction in the ECHS1 protein levels of siECHS1 cells. Constitutive knockdown of the ECHS1 gene in siECHS1 cells was associated with significantly inhibited cell proliferation and migration. We also observed decreased levels of PKB and GSK3β phosphorylation in siECHS1 cells. ECHS1 expression is increased in human gastric cancer cells. Increased ECHS1 expression activates PKB and GSK3β by inducing the phosphorylation of the two kinases. ECHS1 may play important roles in gastric cancer cell proliferation and migration through PKB- and GSK3β-related signaling pathways.

Abstract
Among the cytokines linked to inflammation-associated cancer, interleukin (IL)-6 drives many of the cancer 'hallmarks' through downstream activation of the Janus kinase/signal transducer and activator of transcription 3 (JAK/STAT3) signaling pathway. Additionally, dysregulation of the interleukin (IL)-6-mediated JAK/STAT3 signaling pathway is closely related to the development of diverse human solid tumors including colorectal cancer (CRC). On this basis, modulation of the IL-6/JAK/STAT3 signaling pathway is currently being widely explored to develop novel therapies for CRC. The present review details the mechanisms and roles of the IL-6/JAK/STAT3 pathway in CRC, describes current therapeutic strategies, and the search for potential therapeutic approaches to treat CRC.
