[PMID: 39546956 PMCID: PMC11613166 DOI: 10.1016/j.tranon.2024.102189] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 07/04/2024] [Revised: 10/05/2024] [Accepted: 11/05/2024] [Indexed: 11/17/2024] Open
Abstract
The study highlights that RPS21, a gene encoding a component of the 40S ribosomal subunit, plays an oncogenic role in hepatocellular carcinoma (HCC) and may influence tumor aggressiveness by affecting antioxidant capacity. RPS21 was found to be upregulated in HCC through RNA-sequencing of clinical samples and analysis of the TCGA database. Kaplan-Meier survival analyses linked higher RPS21 expression to lower survival rates across multiple metrics (OS, PFS, RFS, DSS). Mutation analysis via the cBioPortal showed that primarily amplifications in RPS21 are associated with a poorer prognosis. Tissue microarrays confirmed higher RPS21 levels in tumor samples, which were associated with more advanced clinical stages and grades. Experimental interventions involving lentiviral knockdown or overexpression of RPS21 significantly altered HCC cell proliferation and migration. These findings were supported by mouse models, which showed impacts on tumor growth and metastasis. Further mechanistic studies indicated that RPS21 modulates the ubiquitination and stability of GPX4, a key player in ferroptosis and oxidative stress regulation in HCC cells. This comprehensive study, which merges bioinformatic analysis with laboratory research, positions RPS21 as a viable target for HCC therapy and opens new pathways for understanding and treating liver cancer.

Int Immunopharmacol 2024; 142:113096. [PMID: 39288625 DOI: 10.1016/j.intimp.2024.113096] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 06/21/2024] [Revised: 09/02/2024] [Accepted: 09/03/2024] [Indexed: 09/19/2024]
Abstract
BACKGROUND Esophageal squamous cell carcinoma (ESCC) is characterized by high invasiveness and poor prognosis. The role of Sorbin and SH3 domain-containing protein 2 (SORBS2) in ESCC remains largely unexplored. METHODS The expression levels of SORBS2 in ESCC were detected using RNA-seq and proteomics data. The biological functions of SORBS2 in ESCC were investigated through in vivo and in vitro experiments. The mechanism of SORBS2 was explored using RIP-seq technology, which identified the key downstream molecule metalloproteinase-3 (TIMP3). The interaction between SORBS2 and TIMP3, including specific binding sites, was validated through RIP-qPCR and RNA pull-down assays. The impact of altered SORBS2 expression in ESCC on HUVECs was assessed using endothelial tube formation assays. RESULTS SORBS2 expression was significantly downregulated in ESCC tissues, and its decreased expression was associated with poor prognosis. Overexpression of SORBS2 in ESCC cell lines inhibited cell proliferation, migration, and invasion both in vitro and in vivo. Mechanistically, SORBS2 bound to the 3' UTR of TIMP3 mRNA, enhancing its stability and thereby regulating TIMP3 expression. Rescue experiments demonstrated that increased TIMP3 expression could reverse the promotive effects of SORBS2 knockdown on ESCC, confirming TIMP3 as a critical downstream molecule of SORBS2. Furthermore, downregulation of SORBS2 in ESCC cells was associated with activation of HUVEC functions, whereas upregulation of TIMP3 could reverse this effect. The SORBS2/TIMP3 axis may exert tumor suppressive effects by influencing extracellular matrix degradation. CONCLUSION This study confirms that SORBS2 inhibits ESCC tumor progression by regulating extracellular matrix degradation through TIMP3, providing a potential therapeutic target for future treatment interventions.

Exercise and tumor proteome: insights from a neuroblastoma model. Physiol Genomics 2024; 56:833-844. [PMID: 39311839 PMCID: PMC11573273 DOI: 10.1152/physiolgenomics.00064.2024] [Citation(s) in RCA: 1] [Impact Index Per Article: 1.0] [Reference Citation Analysis] [Abstract] [Key Words] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 05/28/2024] [Revised: 09/10/2024] [Accepted: 09/10/2024] [Indexed: 11/12/2024] Open
Abstract
The impact of exercise on pediatric tumor biology is essentially unknown. We explored the effects of regular exercise on tumor proteome profile (as assessed with liquid chromatography with tandem mass spectrometry) in a mouse model of one of the most aggressive childhood malignancies, high-risk neuroblastoma (HR-NB). Tumor samples of 14 male mice (aged 6-8 wk) that were randomly allocated into an exercise (5-wk combined aerobic and resistance training) or nonexercise control group (6 and 8 mice/group, respectively) were analyzed. The Search Tool for the Retrieval of Interacting Genes/Proteins database was used to generate a protein-protein interaction (PPI) network and enrichment analyses. The Systems Biology Triangle (SBT) algorithm was applied for analyses at the functional category level. Tumors of exercised mice showed a higher and lower abundance of 101 and 150 proteins, respectively, than controls [false discovery rate (FDR) < 0.05]. These proteins were enriched in metabolic pathways, amino acid metabolism, regulation of hormone levels, and peroxisome proliferator-activated receptor signaling (FDR < 0.05). The SBT algorithm indicated that 184 and 126 categories showed a lower and higher abundance, respectively, in the tumors of exercised mice (FDR < 0.01). Categories with lower abundance were involved in energy production, whereas those with higher abundance were related to transcription/translation, apoptosis, and tumor suppression. Regular exercise altered the abundance of hundreds of intratumoral proteins and molecular pathways, particularly those involved in energy metabolism, apoptosis, and tumor suppression. These findings provide preliminary evidence of the molecular mechanisms underlying the potential effects of exercise in HR-NB.NEW & NOTEWORTHY We used liquid chromatography with tandem mass spectrometry to explore the impact of a 5-wk exercise intervention on the tumor proteome profile in a mouse model of one of the most aggressive childhood malignancies, high-risk neuroblastoma. Exercise altered the abundance of hundreds of proteins and pathways, particularly those involved in energy metabolism and tumor suppression. These molecular changes could mediate, at least partly, the potential antitumorigenic effects of exercise.

Abstract
N6-methyladenosine (m6A) is the most prevalent internal RNA modification in mammals. However, limited research has been conducted on the role of m6A in coronary artery disease (CAD). We conducted methylated RNA immunoprecipitation sequencing and RNA sequencing to obtain a genome-wide profile of m6A-modified long noncoding RNAs (lncRNAs) in human coronary artery smooth muscle cells either exposed to oxidized low-density lipoprotein treatment or not, and the characteristics of the expression profiles were explored using Gene Ontology and Kyoto Encyclopedia of Genes and Genomes analyses. The predictive effects of seven selected lncRNAs on CAD were evaluated in peripheral blood mononuclear cells (PBMCs). The differentially m6A-modified and expressed lncRNAs related genes were predominantly enriched in small GTPase-mediated signal transduction, ErbB signaling, and Rap1 signaling. Additionally, the expression levels of uc003pes.1, ENST00000422847, and NR_110155 were significantly associated with CAD, with uc003pes.1 identified as an independent risk factor and NR_110155 as an independent protective factor for CAD. NR_110155 and uc003pes.1 in PBMCs have the potential to serve as biomarkers for predicting CAD.

Abstract
The repair of DNA double-strand breaks (DSBs) through homologous recombination (HR) is vital for maintaining the stability and integrity of the genome. RNA binding proteins (RBPs) intricately regulate the DNA damage repair process, yet the precise molecular mechanisms underlying their function remain incompletely understood. In this study, we highlight the pivotal role of RPS15, a representative RBP, in homologous recombination repair. Specifically, we demonstrate that RPS15 promotes DNA end resection, a crucial step in homologous recombination. Notably, we identify an interaction between RPS15 and CtIP, a key factor in homologous recombination repair. This interaction is essential for CtIP recruitment to DSB sites, subsequent RPA coating, and RAD51 replacement, all critical steps in efficient homologous recombination repair and conferring resistance to genotoxic treatments. Functionally, suppressing RPS15 expression sensitizes cancer cells to X-ray radiation and enhances the therapeutic synergistic effect of PARP1 inhibitors in breast cancer cells. In summary, our findings reveal that RPS15 promotes DNA end resection to ensure effective homologous recombination repair, suggesting its potential as a therapeutic target in cancer treatment.

Abstract
The oncofetal mRNA-binding protein IGF2BP1 belongs to a conserved family of RNA-binding proteins. It primarily promotes RNA stability, regulates translation and RNA localization, and mediates gene expression through its downstream effectors. Numerous studies have demonstrated that IGF2BP1 plays crucial roles in embryogenesis and carcinogenesis. IGF2BP1-modulated cell proliferation, invasion, and chemo-resistance in solid tumors have attracted researchers' attention. Additionally, several studies have highlighted the importance of IGF2BP1 in hematologic malignancies and hematological genetic diseases, positioning it as a promising therapeutic target for hematological disorders. However, there is a lack of systematic summaries regarding the IGF2BP1 gene within the hematological field. In this review, we provide a comprehensive overview of the discovery and molecular structure of IGF2BP1, along with recent studies on its role in regulating embryogenesis. We also focus on the mechanisms by which IGF2BP1 regulates hematological malignancies through its interactions with its targeted mRNAs. Furthermore, we systematically elucidate the function and mechanism of IGF2BP1 in promoting fetal hemoglobin expression in adult hematopoietic stem/progenitor cells. Finally, we discuss the limitations and challenges of IGF2BP1 as a therapeutic target, offering insights into its prospects.

Abstract
BACKGROUND Liver metastasis is the most frequently observed distant metastasis of colorectal cancer, and the residual liver recurrence rate after hepatic resection is still high. To explore the mechanism of liver metastasis to discover potential new treatments, we assessed the relationship between the expression of differentially expressed genes (DEGs) and prognosis in patients with colorectal cancer liver metastasis (CRLM). METHODS The gene expression dataset was extracted from The Cancer Genome Atlas and the Gene Expression Omnibus. Significance analysis of DEGs between tumor and normal samples of colorectum, liver, and lung was conducted. A total of 80 CRLM patients were studied to assess the expression of RPS15, characteristics, and outcomes. We examined the relationships of RPS15 expression to cell viability and apoptosis in vitro and vivo. RESULTS Significance analysis identified 33 DEGs. In our cohorts, the overall survival rates were significantly lower in the high-RPS15-expression group, and high expression of RPS15 was an independent and unfavorable prognostic factor in recurrence-free survival and overall survival. Knockdown of RPS15 expression reduced the proliferative capacity of colorectal cancer cells and increased BAX-induced apoptotic cell death. CONCLUSIONS RPS15 expression is an independent prognostic factor for CRLM patients and might be a novel therapeutic target for CRLM.

Abstract
BACKGROUND Metastasis is the leading cause of mortality in patients with colorectal cancer (CRC) and angiogenesis is a crucial factor in tumor invasion and metastasis. Long noncoding RNAs (lncRNAs) play regulatory functions in various biological processes in tumor cells, however, the roles of lncRNAs in CRC-associated angiogenesis remain to be elucidated in CRC, as do the underlying mechanisms. METHODS We used bioinformatics to screen differentially expressed lncRNAs from TCGA database. LOC101928222 expression was assessed by qRT-PCR. The impact of LOC101928222 in CRC tumor development was assessed both in vitro and in vivo. The regulatory mechanisms of LOC101928222 in CRC were investigated by cellular fractionation, RNA-sequencing, mass spectrometric, RNA pull-down, RNA immunoprecipitation, RNA stability, and gene-specific m6A assays. RESULTS LOC101928222 expression was upregulated in CRC and was correlated with a worse outcome. Moreover, LOC101928222 was shown to promote migration, invasion, and angiogenesis in CRC. Mechanistically, LOC101928222 synergized with IGF2BP1 to stabilize HMGCS2 mRNA through an m6A-dependent pathway, leading to increased cholesterol synthesis and, ultimately, the promotion of CRC development. CONCLUSIONS In summary, these findings demonstrate a novel, LOC101928222-based mechanism involved in the regulation of cholesterol synthesis and the metastatic potential of CRC. The LOC101928222-HMGCS2-cholesterol synthesis pathway may be an effective target for diagnosing and managing CRC metastasis.

Abstract
Thioredoxin-interacting protein (TXNIP) is a crucial thioredoxin-binding protein that is recognized as a tumor suppressor in diverse malignancies, such as breast cancer, lung cancer, hepatocellular carcinoma, and thyroid cancer. However, the specific role and molecular mechanisms of TXNIP in the pathogenesis and progression of pancreatic cancer cells have not been determined. In this study, we investigate the relationship between TXNIP expression and overall survival prognosis in pancreatic cancer patients. Mechanistic studies are conducted to reveal the role of TXNIP in pancreatic cancer cell proliferation, migration, and regulation during malignancy. Our findings indicate that patients with high TXNIP expression have a more favorable prognosis. In vitro experiments with pancreatic cell lines show that overexpression of TXNIP suppresses the proliferation and migration of pancreatic cancer cells. Furthermore, we find that TXNIP inhibits the activation of the MAPK signaling pathway, thereby decreasing the malignant potential of pancreatic cancer. In conclusion, our study reveals TXNIP as a promising new predictive marker and therapeutic target for pancreatic cancer.

Abstract
Digestive system tumors have been reported in more than 25% of all cancer cases worldwide, bringing a huge burden on the healthcare system. RNA methylation modification-an important post-transcriptional modification-has become an active research area in gene regulation. It is a dynamic and reversible process involving several enzymes, such as methyltransferases, demethylases, and methylation reader proteins. This review provides insights into the role of three major methylation modifications, namely m6A, m5C, and m1A, in the development of digestive system tumors, specifically in the development of tumor immune microenvironment (TIME) of these malignancies. Abnormal methylation modification affects immunosuppression and antitumor immune response by regulating the recruitment of immune cells and the release of immune factors. Understanding the mechanisms by which RNA methylation regulates digestive system tumors will be helpful in exploring new therapeutic targets.

Abstract
Missense mutations in the DNA binding domain of p53 are observed frequently in esophageal squamous cell carcinoma (ESCC). Recent studies have revealed the potentially oncogenic transcriptional networks regulated by mutant p53 proteins. However, majority of these studies have focused on common "hotspot" p53 mutations while rarer mutations are poorly characterized. In this study, we report the characterization of rare, "non-hotspot" p53 mutations from ESCC. In vitro tumorigenic assays performed following ectopic-expression of certain "non-hotspot" mutant p53 proteins caused enhancement of oncogenic properties in squamous carcinoma cell lines. Genome-wide transcript profiling of ESCC tumor samples stratified for p53 status, revealed several genes exhibiting elevated transcript levels in tumors harboring mutant p53. Of these, ARF6, C1QBP, and TRIM23 were studied further. Reverse transcription-quantitative PCR (RT-qPCR) performed on RNA isolated from ESCC tumors revealed significant correlation of TP53 transcript levels with those of the three target genes. Ectopic expression of wild-type and several mutant p53 forms followed by RT-qPCR, chromatin affinity-purification (ChAP), and promoter-luciferase assays indicated the exclusive recruitment of p53 mutants-P190T and P278L, to the target genes leading to the activation of expression. Several functional assays following knockdown of the target genes revealed a significant suppression of tumorigenicity in squamous carcinoma cell lines. Rescue experiments confirmed the specificity of the knockdown. The tumorigenic effects of the genes were confirmed in nude mice xenograft assays. This study has therefore identified novel oncogenic targets of "non-hotspot" mutant p53 proteins relevant for ESCC besides validating the functional heterogeneity of the spectrum of tumor-specific p53 mutations.

Abstract
Ribosomopathies encompass a spectrum of disorders arising from impaired ribosome biogenesis and reduced functionality. Mutation or dysexpression of the genes that disturb any finely regulated steps of ribosome biogenesis can result in different types of ribosomopathies in clinic, collectively known as ribosomopathy genes. Emerging data suggest that ribosomopathy patients exhibit a significantly heightened susceptibility to cancer. Abnormal ribosome biogenesis and dysregulation of some ribosomopathy genes have also been found to be intimately associated with cancer development. The correlation between ribosome biogenesis or ribosomopathy and the development of malignancies has been well established. This work aims to review the recent advances in the research of ribosomopathy genes among human cancers and meanwhile, to excavate the potential role of these genes, which have not or rarely been reported in cancer, in the disease development across cancers. We plan to establish a theoretical framework between the ribosomopathy gene and cancer development, to further facilitate the potential of these genes as diagnostic biomarker as well as pharmaceutical targets for cancer treatment.

Abstract
Ketamine is the only intravenous narcotic that has sedative, analgesic, and anesthetic effects. However, the role of Flt3l and ribosomal protein S15 (Rps15) in ketamine anesthesia remains unclear. GSE26364 and GSE93041 were downloaded from gene expression omnibus. Multiple datasets were merged and batched. Differentially expressed genes (DEGs) were screened and weighted gene co-expression network analysis was performed. Construction and analysis of protein-protein interaction network. Gene ontology (GO) and Kyoto Encyclopedia of Gene and Genome were performed. A heat map of gene expression was drawn. TargetScan was used to screen miRNAs regulating DEGs. 882 DEGs were identified. According to the GO analysis, these DEGs were mainly enriched in cell differentiation, extracellular region, and cytoplasm. The Kyoto Encyclopedia of Gene and Genome analysis revealed enrichment in pathways such as the PPAR signaling pathway, TNF signaling pathway, Hippo signaling pathway, and IL-17 signaling pathway. In the Metascape enrichment analysis, GO enrichment categories included leukocyte differentiation, negative regulation of CREB transcription factor activity, and positive regulation of cell cycle. The protein-protein interaction network showed 10 core genes (Rpl7, Rpl18, Rps15, Rpl7l1, Flt3l, Rps16, Eprs, Rps19, Rps28, Rplp2).Gene expression heatmap showed that core genes (Rplp2, Flt3l, Rps15) were highly expressed in samples treated with ketamine anesthesia. Flt3l and Rps15 are highly expressed during ketamine anesthesia, and may be molecular targets.

Abstract
Dysregulated protein synthesis is a hallmark of tumors. mRNA translation reprogramming contributes to tumorigenesis, which is fueled by abnormalities in ribosome formation, tRNA abundance and modification, and translation factors. Not only malignant cells but also stromal cells within tumor microenvironment can undergo transformation toward tumorigenic phenotypes during translational reprogramming. Ribosome-inactivating proteins (RIPs) have garnered interests for their ability to selectively inhibit protein synthesis and suppress tumor growth. This review summarizes the role of dysregulated translation machinery in tumor development and explores the potential of RIPs in cancer treatment.

Abstract
Neuropathic pain (NP) is a common chronic pain condition resulted from lesions or diseases of somatosensory nervous system, but the pathogenesis remains unclear. A growing body of evidence supports the relationship between pathogenesis and N6-methyladenosine (m6A) modifications of RNA. However, studies on the role of m6A modifications in NP are still at an early stage. Elucidating different etiologies is important for understanding the specific pathogenesis of NP. This article provides a comprehensive review on the role of m6A methylation modifications including methyltransferases ("writers"), demethylases ("erasers"), and m6A binding proteins ("readers") in NP models. Further analysis of the pathogenic mechanism relationship between m6A and NP provided novel theoretical and practical significance for clinical treatment of NP.
