Epithelial–mesenchymal transition (EMT) is a trigger for CRC to acquire a malignant phenotype, such as invasive potential, leading to metastasis. However, the role of AMIGO2 expression in the invasive potential of CRC cells remains unclear. Thus, this study aimed to examine AMIGO2 expression and elucidate the mechanisms by which it induces EMT and promotes CRC invasion. Activation of the TGFβ/Smad signaling pathway was found involved in AMIGO2-induced EMT, and treatment with the TGFβ receptor inhibitor LY2109761 suppressed AMIGO2-induced EMT. Studies using CRC samples showed that AMIGO2 expression was highly upregulated in the invasive front, where AMIGO2 expression was localized to the nucleus and associated with EMT marker expression. These results suggest that the nuclear translocation of AMIGO2 induces EMT to promote CRC invasion by activating the TGFβ/Smad signaling pathway. Thus, AMIGO2 is an attractive therapeutic target for inhibiting EMT and metastatic CRC progression.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"31 12","pages":"1786-1795"},"PeriodicalIF":4.8,"publicationDate":"2024-10-08","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142388255","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Cancer stem cells (CSCs) play important roles in the occurrence, development, recurrence, and metastasis of CRC. The molecular mechanism regulating the development of colorectal CSCs remains unclear. The discovery of human induced pluripotent stem cells (hiPSCs) through somatic cell reprogramming has revolutionized the fields of stem cell biology and translational medicine. In the present study, we converted hiPSCs into cancer stem-like cells by culture with conditioned medium (CM) from CRC cells. These transformed cells, termed hiPSC-CSCs, displayed cancer stem-like properties, including a spheroid morphology and the expression of both pluripotency and CSC markers. HiPSC-CSCs showed tumorigenic and metastatic abilities in mouse models. The epithelial-mesenchymal transition phenotype was observed in hiPSC-CSCs, which promoted their migration and angiogenesis. Interestingly, upregulation of C-MYC was observed during the differentiation of hiPSC-CSCs. Mechanistically, CREB binding protein (CBP) bound to the C-MYC promoter, while histone deacetylase 1 and 3 (HDAC1/3) dissociated from the promoter, ultimately leading to an increase in histone acetylation and C-MYC transcriptional activation during the differentiation of hiPSC-CSCs. Pharmacological treatment with a CBP inhibitor or abrogation of CBP expression with a CRISPR/Cas9-based strategy reduced the stemness of hiPSC-CSCs. This study demonstrates for the first time that colorectal CSCs can be generated from hiPSCs. The upregulation of C-MYC via histone acetylation plays a crucial role during the conversion process. Inhibition of CBP is a potential strategy for attenuating the stemness of colorectal CSCs.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"31 11","pages":"1734-1748"},"PeriodicalIF":4.8,"publicationDate":"2024-10-02","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142364518","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

The study of the tumor microbiota offers a new perspective for the diagnosis and treatment of cancer, and it holds the potential for the development of new diagnostic tools and therapies. The role of the tumor microbiota in the pathogenesis of cancer is becoming increasingly evident, and future research will continue to uncover the specific mechanisms of action of these microbes, potentially shedding light on new strategies and methods for cancer prevention and therapy.

Herein, we comprehensively summarize, compare, and contrast the research advancements on the role of miR-301a in different cancers. Differential expression patterns of miR-301a in tissues and biofluids are implicated in cancer diagnosis, treatment response, and prognosis. MiR-301a modulates the expression of multiple genes, other noncoding RNAs, and signaling cascade via direct or indirect regulation in human cancer proliferation, migration, invasion, angiogenesis, and radio- or chemotherapy resistance. Cancer cell-associated miR-301a affects the tumor microenvironment through the alteration of immune function and cancer metabolism.

This approach relies on intramuscular injection of DNA expressing antigens of interest fused at a biologically-inactive HIV-1 Nef protein mutant (Nefmut). Nefmut is very efficiently incorporated into EVs, thus conveying large amounts of fusion proteins into EVs released by transfected cells. This platform proved successful against highly immunogenic tumor-specific antigens. Here, we tested whether antigen-specific CD8+ T cell immune responses induced by engineered EVs can counteract the growth of tumors expressing two “self” tumor-associated antigens (TAAs): HOXB7 and Her2/neu. FVB/N mice were injected with DNA vectors expressing Nefmut fused to HOXB7 or Her2/neu, singly and in combination, before subcutaneous implantation of breast carcinoma cells co-expressing HOXB7 and Her2/neu. All mice immunized with the combination vaccine remained tumor-free, whereas groups vaccinated with single Nefmut-fused antigens were only partly protected, with stronger antitumor effects in Her2/neu-immunized mice. Double-vaccinated mice also controlled tumor growth upon a later tumor cell re-challenge. Importantly, co-vaccination also contained tumors in a therapeutic immunization setting. These results showed the efficacy of EV-based vaccination against two TAAs, and represent the first demonstration that HOXB7 may be targeted in multi-antigen immunotherapy strategies.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"31 11","pages":"1688-1695"},"PeriodicalIF":4.8,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41417-024-00831-2.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142280637","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

We conducted in vitro and in vivo assays to assess the role of PARD6A in regulating lung cancer progression, including proliferation, wound healing, transwell, RNA-seq, and subcutaneous tumor mice models.

In vitro assays showed that PARD6A promoted cell proliferation, migration, and invasion. The transcriptome sequencing identified Serpina3 as one of the key downstream molecules of PARD6A. Ectopic expression of Serpina3 rescued impaired proliferation, migration, and invasion in PARD6A-knocking down H1299 cells, whereas silencing Serpina3 impeded enhanced proliferation, migration, and invasion in PARD6A-overexpressing H1975 cells.

Colony formation, scratch healing, Transwell and CCK-8 assays were conducted to evaluate the effects of circMBOAT2 in the presence or absence of norepinephrine (NE) treatment on the proliferation, migration, and invasion of NSCLC cells, respectively. Additionally, A chronic unpredictable mild stress (CUMS)-induced depression with heterotopic transplantation LLC and injection of antisense oligonucleotides (ASOs) targeting circMBOAT2 mouse model was established to evaluate the effect of chronic stress on tumorigenesis via circMBOAT2. Moreover, we investigated the regulatory effect of CCCTC binding factor (CTCF) on circMBOAT2 expression through in vivo and in vitro silencing of CTCF. Our results revealed a significant upregulation of circMBOAT2 in NSCLC cell lines and tumor tissues. circMBOAT2 knockdown inhibited the proliferation, migration, and invasion of NSCLC cells, while NE treatment reversed the cell suppression effect caused by circMBOAT2 knockdown. Notably, CUMS promoted tumor growth, while silencing circMBOAT2 inhibited tumor growth in vivo. Furthermore, we identified CTCF as the upstream regulator of circMBOAT2, which exhibited upregulation in NSCLC cells and tissues. Knockdown of CTCF reversed the promotional effect of CUMS on circMBOAT2 expression and tumor growth. Our findings provide evidence that CTCF mediates chronic stress in promoting of NSCLC progression through circMBOAT2. circMBOAT2 may serve as a potential biomarker and therapeutic target for NSCLC as well as the treatment of comorbid depression in NSCLC patients.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"31 11","pages":"1721-1733"},"PeriodicalIF":4.8,"publicationDate":"2024-09-19","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.nature.com/articles/s41417-024-00830-3.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142280636","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In our investigation, we identified HN1’s heightened expression in HCC tissues, which, upon overexpression, fosters cell proliferation, migration, and invasion, unveiling its role as an oncogene in HCC. In addition, silencing HN1 diminished the viability and metastasis of HCC cells, whereas HN1 overexpression stimulated their growth and invasion. Gene expression profiling revealed HN1 silencing downregulated 379 genes and upregulated 130 genes, and suppressive proteins associated with the lipogenic signaling pathway networks. Notably, suppressing HN1 markedly decreased the expression levels of SREBP1 and SREBP2, whereas elevating HN1 had the converse effect. This dual modulation of HN1 affected lipid formation, hindering it upon HN1 silencing and promoting it upon HN1 overexpression. Moreover, HN1 triggers the Akt pathway, fostering tumorigenesis via SREBP1-mediated lipogenesis and silencing HN1 effectively curbed HCC tumor growth in mouse xenograft models by deactivating SREBP-1, emphasizing the potential of HN1 as a therapeutic target, impacting both external and internal factors, it holds promise as an effective therapeutic strategy for HCC.","PeriodicalId":9577,"journal":{"name":"Cancer gene therapy","volume":"31 11","pages":"1669-1687"},"PeriodicalIF":4.8,"publicationDate":"2024-09-09","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142198233","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":3,"RegionCategory":"医学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
