Cell surface CD55 traffics to the nucleus leading to cisplatin resistance and stemness by inducing PRC2 and H3K27 trimethylation on chromatin in ovarian cancer. Mol Cancer 2024; 23:121. [PMID: 38853277 PMCID: PMC11163727 DOI: 10.1186/s12943-024-02028-5] [Citation(s) in RCA: 0] [Impact Index Per Article: 0] [Reference Citation Analysis] [Abstract] [MESH Headings] [Grants] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/01/2024] [Accepted: 05/22/2024] [Indexed: 06/11/2024] Open
Abstract
BACKGROUND Platinum resistance is the primary cause of poor survival in ovarian cancer (OC) patients. Targeted therapies and biomarkers of chemoresistance are critical for the treatment of OC patients. Our previous studies identified cell surface CD55, a member of the complement regulatory proteins, drives chemoresistance and maintenance of cancer stem cells (CSCs). CSCs are implicated in tumor recurrence and metastasis in multiple cancers. METHODS Protein localization assays including immunofluorescence and subcellular fractionation were used to identify CD55 at the cell surface and nucleus of cancer cells. Protein half-life determinations were used to compare cell surface and nuclear CD55 stability. CD55 deletion mutants were generated and introduced into cancer cells to identify the nuclear trafficking code, cisplatin sensitivity, and stem cell frequency that were assayed using in vitro and in vivo models. Detection of CD55 binding proteins was analyzed by immunoprecipitation followed by mass spectrometry. Target pathways activated by CD55 were identified by RNA sequencing. RESULTS CD55 localizes to the nucleus of a subset of OC specimens, ascites from chemoresistant patients, and enriched in chemoresistant OC cells. We determined that nuclear CD55 is glycosylated and derived from the cell surface pool of CD55. Nuclear localization is driven by a trafficking code containing the serine/threonine (S/T) domain of CD55. Nuclear CD55 is necessary for cisplatin resistance, stemness, and cell proliferation in OC cells. CD55 S/T domain is necessary for nuclear entry and inducing chemoresistance to cisplatin in both in vitro and in vivo models. Deletion of the CD55 S/T domain is sufficient to sensitize chemoresistant OC cells to cisplatin. In the nucleus, CD55 binds and attenuates the epigenetic regulator and tumor suppressor ZMYND8 with a parallel increase in H3K27 trimethylation and members of the Polycomb Repressive Complex 2. CONCLUSIONS For the first time, we show CD55 localizes to the nucleus in OC and promotes CSC and chemoresistance. Our studies identify a therapeutic mechanism for treating platinum resistant ovarian cancer by blocking CD55 nuclear entry.

Abstract
Cancer stem cells (CSCs) represent a subpopulation within tumors that promote cancer progression, metastasis, and recurrence due to their self-renewal capacity and resistance to conventional therapies. CSC-specific markers and signaling pathways highly active in CSCs have emerged as a promising strategy for improving patient outcomes. This review provides a comprehensive overview of the therapeutic targets associated with CSCs of solid tumors across various cancer types, including key molecular markers aldehyde dehydrogenases, CD44, epithelial cellular adhesion molecule, and CD133 and signaling pathways such as Wnt/β-catenin, Notch, and Sonic Hedgehog. We discuss a wide array of therapeutic modalities ranging from targeted antibodies, small molecule inhibitors, and near-infrared photoimmunotherapy to advanced genetic approaches like RNA interference, CRISPR/Cas9 technology, aptamers, antisense oligonucleotides, chimeric antigen receptor (CAR) T cells, CAR natural killer cells, bispecific T cell engagers, immunotoxins, drug-antibody conjugates, therapeutic peptides, and dendritic cell vaccines. This review spans developments from preclinical investigations to ongoing clinical trials, highlighting the innovative targeting strategies that have been informed by CSC-associated pathways and molecules to overcome therapeutic resistance. We aim to provide insights into the potential of these therapies to revolutionize cancer treatment, underscoring the critical need for a multi-faceted approach in the battle against cancer. This comprehensive analysis demonstrates how advances made in the CSC field have informed significant developments in novel targeted therapeutic approaches, with the ultimate goal of achieving more effective and durable responses in cancer patients.

Abstract
BACKGROUND PAX1 gene methylation plays an important role in the development of cervical cancer. However, its prognostic value after radiotherapy for locally advanced cervical cancer is unknown, so this study aimed to investigate the value of PAX1 gene methylation for predicting the sensitivity of radiotherapy for cervical cancer. METHODS We selected 125 patients with primary cervical cancer who underwent concurrent chemo-radiotherapy as the study population, quantitative methylation-specific polymerase chain reaction (QMSP) was used for detecting PAX1 methylation status of cervical exfoliated cells. Logistic regression model was used to analyze the risk factors associated with the short-term efficacy and to establish a prediction model of radiotherapy sensitivity based on PAX1 gene methylation. Cell viability after radiation of Hela and SiHa cells transfected with PAX1 or control vector was evaluated by CCK8. Furthermore, RNA-Seq analyses identified different expressed genes (DEGs) in PAX1 overexpressed SiHa cells. Gene Ontology (GO) and pathway enrichment analysis was carried out to determine the biological function of DEGs. RESULTS PAX1 methylation level was associated with HPV16/18-positive rate. PAX1 hypomethylation was found to be a risk factor for tumor residual after chemo-radiotherapy. A nomogram containing the risk factors for PAX1 methylation status, lymph node metastasis, pathological type and tumor size was further constructed to predict the probability of tumor residual after chemo-radiotherapy (AUC = 0.823, 95% CI 0.736-0.910). High PAX1 protein level was more likely to cause radioresistance in both Hela and SiHa cells. Transcriptomic sequencing of PAX1 overexpressed and control cells identified 615 differentially expressed genes, and GO enrichment analysis suggested that PAX1 may be involved in the regulation of signaling receptor activity and response to viruses. CONCLUSION PAX1 hypomethylation status could be used as a promising biomarker to predict radioresistance in cervical cancer. This further provides a new idea for the individualized treatment strategy of simultaneous radiotherapy for cervical cancer.

Abstract
CD55, or decay accelerating factor, is a membrane lipid microdomain-associated, GPI-anchored protein implicated in the shielding of cells from complement-mediated attack via accelerating decay of C3 and C5. Loss of CD55 is associated with a number of pathologies due to hyperactivation of the complement system. CD55 is also implicated in cancer progression thought to be driven via its role in cell shielding mechanisms. We now appreciate that CD55 can signal intracellularly to promote malignant transformation, cancer progression, cell survival, angiogenesis, and inhibition of apoptosis. Outside-in signaling via CD55 is mediated by signaling pathways including JNK, JAK/STAT, MAPK/NF-κB, and LCK. Moreover, CD55 is enriched in the cancer stem cell (CSC) niche of multiple tumors including breast, ovarian, cervical, and can be induced by chemotherapeutics and hypoxic environments. CSCs are implicated in tumor recurrence and chemoresistance. Here, we review the unexpected roles of CD55 in cancer including the roles of canonical and noncanonical pathways that CD55 orchestrates. We will highlight opportunities for therapeutic targeting CD55 and gaps in the field that require more in-depth mechanistic insights.

Abstract
A novel gene editing tool, the Cas system, associated with the CRISPR system, is emerging as a potential method for genome modification. This simple method, based on the adaptive immune defense system of prokaryotes, has been developed and used in human cancer research. These technologies have tremendous therapeutic potential, especially in gene therapy, where a patient-specific mutation is genetically corrected to cure diseases that cannot be cured with conventional treatments. However, translating CRISPR/Cas9 into the clinic will be challenging, as we still need to improve the efficiency, specificity, and application of the technology. In this review, we will explain how CRISPR-Cas9 technology can treat cancer at the molecular level, focusing on ordination and the epigenome. We will also focus on the promise and shortcomings of this system to ensure its application in the treatment and prevention of cancer.

Abstract
Human papillomavirus infections are associated with most cervical cancers, which are the fourth most common cancer in women. HPV-E6 protein binds to protein p53 and inhibits its function, leading to the switching of normal cells toward cancer cells. Here, we disrupted the HPV-E6 gene and investigated its effects on the proliferation and apoptosis of HeLa cells. The HPV18-E6 gene was targeted with two designed sgRNAs cloned into an AAV-CRISPR-based plasmid. The AAV-E6-CRISPR/Cas9 virions were prepared and titrated in HEK293t cells. The cleavage created in the HPV-E6 gene was detected using the T7E1 assay. Cell cycle profiling, MTT assay, and annexin V/PI staining were performed. Also, the p53 protein level was measured by Western blotting. Our data showed that disruption of the HPV-E6 gene led to increased cell apoptosis and decreased cell proliferation. A significant accumulation of infected cells in sub-G1 phase was observed in the cell profiling assay. Also, HPV-E6 gene disruption resulted in a significant increase in the level of P53 protein. Our findings indicated that AAV-mediated delivery of CRISPR/Cas9 can effectively target the HPV-E6 gene in HeLa cells, and its antiproliferative effects may provide therapeutic benefits of local administration of this gene-editing system for HPV-related cervical cancers.

Abstract
PURPOSE Hypoxia (low oxygen) is a common feature of solid tumors that has been intensely studied for more than six decades. Here we review the importance of hypoxia to radiotherapy with a particular focus on the contribution of hypoxia to immune responses, metastatic potential and FLASH radiotherapy, active areas of research by leading women in the field. CONCLUSION Although hypoxia-driven metastasis and immunosuppression can negatively impact clinical outcome, understanding these processes can also provide tumor-specific vulnerabilities that may be therapeutically exploited. The different oxygen tensions present in tumors and normal tissues may underpin the beneficial FLASH sparing effect seen in normal tissue and represents a perfect example of advances in the field that can leverage tumor hypoxia to improve future radiotherapy treatments.

Abstract
The biological function of PRMT5 remains poorly understood in cervical cancer metastasis. Here, we report that PRMT5 physically associates with the transcription factor Snail and the NuRD(MTA1) complex to form a transcriptional-repressive complex that catalyzes the symmetrical histone dimethylation and deacetylation. This study shows that the Snail/PRMT5/NuRD(MTA1) complex targets genes, such as TET1 and E-cadherin, which are critical for epithelial-mesenchymal transition (EMT). This complex also affects the conversion of 5mC to 5hmC. This study demonstrates that the Snail/PRMT5/NuRD(MTA1) complex promotes the invasion and metastasis of cervical cancer in vitro and in vivo. This study also shows that PRMT5 expression is upregulated in cervical cancer and various human cancers, and the PRMT5 inhibitor EPZ015666 suppresses EMT and the invasion potential of cervical cancer cells by disinhibiting the expression of TET1 and increasing 5hmC, suggesting that PRMT5 is a potential target for cancer therapy.

Abstract
High-risk human papillomavirus (HPV) E6 and E7 genes display vital oncogenic properties in cervical cancer. Eliminating HPV driver gene or loss of function by the clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9 system is a promising treatment for the HPV-associated cancer. Thus, this study designed a CRISPR/Cas9 system to target the E6 and E7 genes at once, to detect whether it have efficacy in vitro and in vivo. Meanwhile, CRISPR/Cas9 system was measured after transfection with liposomes but virus. Cervical cancer lines (HeLa and SiHa) were used in this study. Sanger sequencing confirmed that the single CRISPR/Cas9 vector [termed E6E7-knockout (KO)] containing guide RNAs could targeting both HPV18 E6 and E7 genes in vitro. In addition, double-targeting E6 and E7 increased p53 protein expression significantly while compared with E6 or E7 targeting, respectively. Mice with xenografts were divided into four groups: three doses of experimental groups (20, 40, and 60 μg) and one control group. The E6E7-KO through liposome delivery was injected into tumors. Tumor growth was measured and protein expression was observed through immunohistochemistry. The toxic side effects in vivo were also evaluated. E6E7-KO induced cell apoptosis and inhibited cell proliferation markedly in vitro. E6E7-KO downregulated the messenger RNA and protein expression of E6 and E7, whereas p53 and p21 protein levels were upregulated accordingly. Notably, E6E7-KO delivery by liposome exhibited an effect in vivo. Tumor growth was inhibited in the E6E7-KO groups, which was accompanied by decreased E6/E7 protein expression and increased p53/p21 protein expression, especially the level of p53 protein expression. Therefore, E6E7-KO could have synergy efficient by p53 pathway. Furthermore, local injection with CRISPR/Cas9 by nonviral delivery may be regarded as a potential therapy for cervical cancer in the future.

Abstract
BACKGROUND The second most common malignant cancer of the uterus is cervical cancer, which is present worldwide, has a rising death rate and is predominant in developing countries. Different classes of anticancer agents are used to treat cervical carcinoma. The use of these agents results in severe untoward side-effects, toxicity, and multidrug resistance (MDR) with higher chances of recurrence and spread beyond the pelvic region. Moreover, the resulting clinical outcome remains very poor even after surgical procedures and treatment with conventional chemotherapy. Because of the nonspecificity of their use, the agents wipe out both cancerous and normal tissues. Colloidal nano dispersions have now been focusing on site-specific delivery for cervical cancer, and there has been much advancement. METHODS This review aims to highlight the problems in the current treatment of cervical cancer and explore the potential of colloidal nanocarriers for selective delivery of anticancer drugs using available literature. RESULTS In this study, we surveyed the role and potential of different colloidal nanocarriers in cervical cancer, such as nanoemulsion, nanodispersions, polymeric nanoparticles, and metallic nanoparticles and photothermal and photodynamic therapy. We found significant advancement in colloidal nanocarrier-based cervical cancer treatment. CONCLUSION Cervical cancer-targeted treatment with colloidal nanocarriers would hopefully result in minimal toxic side effects, reduced dosage frequency, and lower MDR incidence and enhance the patient survival rates. The future direction of the study should be focused more on the regulatory barrier of nanocarriers based on clinical outcomes for cervical cancer targeting with cost-effective analysis.

Abstract
Senescence induction and epithelial-mesenchymal transition (EMT) events are the opposite sides of the spectrum of cancer phenotypes. The key molecules involved in these processes may get influenced or altered by genetic and epigenetic changes during tumor progression. Double C2-like domain beta (DOC2B), an intracellular vesicle trafficking protein of the double C2 protein family, plays a critical role in exocytosis, neurotransmitter release, and intracellular vesicle trafficking. DOC2B is repressed by DNA promoter hypermethylation and functions as a tumor growth regulator in cervical cancer. To date, the molecular mechanisms of DOC2B in cervical cancer progression and metastasis is elusive. Herein, the biological functions and molecular mechanisms regulated by DOC2B and its impact on senescence and EMT are described. DOC2B inhibition promotes proliferation, growth, and migration by relieving G0/G1-S arrest, actin remodeling, and anoikis resistance in Cal27 cells. It enhanced tumor growth and liver metastasis in nude mice with the concomitant increase in metastasis-associated CD55 and CD61 expression. Inhibition of EMT and promotion of senescence by DOC2B is a calcium-dependent process and accompanied by calcium-mediated interaction between DOC2B and CDH1. In addition, we have identified several EMT and senescence regulators as targets of DOC2B. We show that DOC2B may act as a metastatic suppressor by inhibiting EMT through induction of senescence via DOC2B-calcium-EMT-senescence axis.

Abstract
BACKGROUND A major challenge in cervical cancer radiotherapy is to tailor the radiation doses efficiently to both eliminate malignant cells and to reduce the side effects to normal tissue. Oncolytic adenoviral drug H101 is recently tested and approved for topical adjuvant treatment of several malignancies. OBJECTIVE This study is to evaluate the potential neoadjuvant radiotherapy benefits of H101 by testing the inhibitory function of H101 combined with radiation in different cervical cancer cells. METHODS Human cervical cancer cells C33a, SiHa, CaSki, and Hela were treated with varying concentrations of H101 alone or combined with radiation (2Gy or 4Gy). Cell viability and apoptosis were measured at indicated time intervals. HPV16 E6 and cellular p53 mRNA expression alteration were measured by qRT-PCR. RNA scope in-situ detect HPV E6 status. P53 protein alteration are detected by Western blot. RESULTS Cell viability and apoptosis show the combination of a high dose of H101 (MOI=1000, 10000) with radiation yielded a synergistic anti-cancer effect in all tested cervical cancer cell lines (P<0.05), with the greatest effect achieved in HPV negative C33a cells (P<0.05). Low HPV16 viral load SiHa cell was more sensitive to combination therapy than high HPV16 viral load CaSki cell (P<0.05). The combined treatment could reduce HPV16 E6 expression and increase cellular P53 level compared to radiation alone in SiHa and CaSki (P<0.05). CONCLUSIONS Oncolytic adenoviral H101 effectively enhances the antitumor efficacy of radiation in cervical cancer cells and may serve as a novel combination therapy for cervical cancer.

Abstract
Infection with human papillomavirus (HPV) is one of the main causes of malignant neoplasms, especially cervical, anogenital, and oropharyngeal cancers. Although we have developed preventive vaccines that can protect from HPV infection, there are still many new cases of HPV-related cancers worldwide. Early diagnosis and therapy are therefore important for the treatment of these diseases. As HPVs are the major contributors to these cancers, it is reasonable to develop reagents, kits, or devices to detect and eliminate HPVs for early diagnosis and therapeutics. Immunological methods are precise strategies that are promising for the accurate detection and blockade of HPVs. During the last decades, the mechanism of how HPVs induce neoplasms has been extensively elucidated, and several oncogenic HPV early proteins, including E5, E6, and E7, have been shown to be positively related to the oncogenesis and malignancy of HPV-induced cancers. These oncoproteins are promising biomarkers for diagnosis and as targets for the therapeutics of HPV-related cancers. Importantly, many specific monoclonal antibodies (mAbs), or newly designed antibody mimics, as well as new immunological kits, devices, and reagents have been developed for both the immunodiagnosis and immunotherapeutics of HPV-induced cancers. In the current review, we summarize the research progress in the immunodiagnosis and immunotherapeutics based on HPV for HPV-induced cancers. In particular, we depict the most promising serological methods for the detection of HPV infection and several therapeutical immunotherapeutics based on HPV, using immunological tools, including native mAbs, radio-labelled mAbs, affitoxins (affibody-linked toxins), intracellular single-chain antibodies (scFvs), nanobodies, therapeutical vaccines, and T-cell-based therapies. Our review aims to provide new clues for researchers to develop novel strategies and methods for the diagnosis and treatment of HPV-induced tumors.

Abstract
Pancreatic cancer is one of the most life-threatening malignancies worldwide. Despite advances in checkpoint immunotherapy for patients with cancer, the current immunotherapies have demonstrated limited benefits for the treatment of pancreatic cancer. Apart from the intricate microenvironments that restrict T-cell function, membrane proteins other than programmed death-ligand 1 may also facilitate immune escape of tumor cells. The present study investigated the membrane proteins of seven paired pancreatic adenocarcinoma (PAAD) and adjacent normal tissues with mass spectrometry, and identified 10 up-and eight downregulated membrane proteins in PAAD. Together with the online database analysis, the results showed that the CASK protein was upregulated in PAAD samples and cell lines, and predicts poor outcomes in patients with PAAD. Furthermore, the results exhibited downregulated CD36 and EPB42 in PAAD samples and cell lines, and higher levels of CD36. EPB42 was shown to predict improved survival outcomes in patients with PAAD. Overall, the results of the present study revealed PAAD-specific membrane proteins as potential diagnostic markers and drug-targets for the immunotherapy of pancreatic cancer.

Abstract
Human papillomavirus (HPV) is the etiological agent of cervical cancer; however, the mechanisms underlying HPV-mediated carcinogenesis remain poorly understood. Here, we showed that nuclear receptor related-1 protein (Nurr1) was upregulated in primary cervical cancer tissue-derived spheroid cells and HPV-positive cell lines, and Nurr1 upregulation was correlated with cancer grade. Nurr1 promoted cell proliferation, migration, invasion, and anchorage-independent cell growth. In addition to its effect on cancer aggressiveness, Nurr1 enhanced the self-renewal ability of cells in vitro and in vivo, underscoring the importance of Nurr1 in maintaining the stemness of cancer stem-like cells (CSLCs). Mechanistically, Nurr1 independently activated the MEK/ERK and PI3K/Akt/mTOR signaling cascades. The MEK inhibitor trametinib (GSK) and PI3K/mTOR dual inhibitor dactolisib (BEZ) were shown to abrogate Nurr1-augmented tumorigenesis by upregulating p21 and p27 expression and by suppressing MMP9 and KLF4 expression. We provided further evidence that BEZ, but not GSK, could abolish Nurr1-enhanced radioresistance, suggesting its potential value for radiosensitizing CSLCs in the clinical setting. This study highlights the unprecedented roles of Nurr1 and elucidates mechanisms by which Nurr1 promotes tumor progression and radioresistance, providing a novel therapeutic strategy for cervical cancer treatment.

Abstract
Background CD109 was involved in the tumorigenesis and progression of various cancers via TGF-β1 signalling and STAT3 activation. As CD109 is strongly expressed in cervical squamous cell carcinoma, this study was conducted to investigate its functional characteristics in cervical cancer. Methods CD109 expression was examined by immunohistochemistry (IHC) with cervical tissue microarray. The effects of CD109 expression were examined on migration, cell proliferation, spheroid formation and soft-agar colony-formation assay. Meanwhile, cervical cancer cell lines with high CD109 expression were chosen for the functional study using siRNA knockdown and CRISPR/Cas9 knockout. Results IHC demonstrated an upregulation of CD109 in the cell membrane of cervical squamous cell carcinoma. CD109( + ) cells isolated by flow-cytometric sorting displayed enhanced migration, cell proliferation, sphere-forming and anchorage-independent cell growth ability. In contrast, silencing of CD109 expression could reverse the in vitro and in vivo tumorigenic and aggressive properties. Furthermore, CD109 induced EGFR-mediated STAT3 phosphorylation known to be responsible for cell migration, proliferation and maintenance of CSC phenotype. Conclusion Abundant CD109( + ) populations in cervical cancer cells potentially contributed to carcinogenesis and aggressiveness, whereas silencing of CD109 expression could reverse those properties. CD109 mediates cervical tumorigenicity and aggressiveness via CD109/EGFR/STAT3 signalling.

Engeletin suppresses cervical carcinogenesis in vitro and in vivo by reducing NF-κB-dependent signaling. Biochem Biophys Res Commun 2020; 526:497-504. [PMID: 32241545 DOI: 10.1016/j.bbrc.2020.03.091] [Citation(s) in RCA: 9] [Impact Index Per Article: 2.3] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/02/2020] [Accepted: 03/16/2020] [Indexed: 12/16/2022]
Abstract
Cervical cancer is an aggressive human cancer with poor prognosis among women, and urgently requires effective treatments. Engeletin (ENG, dihydrokaempferol 3-rhamnoside), as a flavanonol glycoside, could be found in various kinds of vegetables and fruits, exerting significant anti-inflammatory biological activities. However, its role in regulating cervical cancer, as well as the underlying molecular mechanisms are still unknown. In this study, we found that ENG treatments dose-dependently reduced the proliferation of cervical cancer cells. Epithelial to mesenchymal transition (EMT) process in cervical cancer was also restrained by ENG using transwell analysis, as evidenced by the significantly reduced migration and invasion. In addition, ENG treatments restricted vascular endothelial growth factor-A (VEGFA) expression in cervical cancer cells, contributing to the suppression of angiogenesis. Mechanistically, ENG significantly reduced the expression of chemokine (C-C motif) ligand 2 (CCL2) in cervical cancer cells associated with the blockage of nuclear factor-κB (NF-κB) signaling pathway. Moreover, ENG functioned as an inhibitor of NF-κB, which was involved in the repression of angiogenesis. In xenograft model, ENG treatment effectively reduced the tumor volume and weight, accompanied with decreased expression of phosphorylated NF-κB, CCL2 and VEGFA, and showed little influence on the body weight change. Therefore, ENG might be a potential therapeutic strategy for the treatment of cervical cancer.

Abstract
Radiotherapy is an important treatment of cervical cancer, especially for advanced cervical cancer. According to research reports, Hedgehog signaling pathway plays an essential role in the growth, invasion, metastasis, recurrence, drug resistance, and radioresistance of cervical cancer. The components of Hedgehog signaling pathway could be biomarkers, related to progression and prognosis of cervical cancer. In addition, targeted therapy for Hedgehog signaling pathway is expected to become a new strategy for the treatment of radioresistant cervical cancer. This review summarizes the research status and progress of the relationship between radiation resistance and activation of Hedgehog signaling pathway in cervical cancer.

Abstract
In recent years, gene editing, especially that using clustered regularly interspaced short palindromic repeat (CRISPR)/Cas9, has made great progress in the field of gene function. Rapid development of gene editing techniques has contributed to their significance in the field of medicine. Because the CRISPR/Cas9 gene editing tool is not only powerful but also has features such as strong specificity and high efficiency, it can accurately and rapidly screen the whole genome, facilitating the administration of gene therapy for specific diseases. In the field of tumor research, CRISPR/Cas9 can be used to edit genomes to explore the mechanisms of tumor occurrence, development, and metastasis. In these years, this system has been increasingly applied in tumor treatment research. CRISPR/Cas9 can be used to treat tumors by repairing mutations or knocking out specific genes. To date, numerous preliminary studies have been conducted on tumor treatment in related fields. CRISPR/Cas9 holds great promise for gene-level tumor treatment. Personalized and targeted therapy based on CRISPR/Cas9 will possibly shape the development of tumor therapy in the future. In this study, we review the findings of CRISPR/Cas9 for tumor treatment research to provide references for related future studies on the pathogenesis and clinical treatment of tumors.

Mol Cancer Res 2019; 17:1867-1880. [PMID: 31235657 DOI: 10.1158/1541-7786.mcr-19-0068] [Citation(s) in RCA: 6] [Impact Index Per Article: 1.2] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 01/22/2019] [Revised: 05/01/2019] [Accepted: 06/18/2019] [Indexed: 11/16/2022]
Abstract
A subpopulation of cells within tumors has been suggested to possess the ability to initiate tumorigenesis and contribute to resistance to cancer therapy. Identification and isolation of this subpopulation in cancer cells can be achieved by detecting specific cell-surface markers. In this study, flow cytometry analysis revealed an abundant CD71+ subpopulation in human papillomavirus (HPV)-positive cervical cancer cells, while limited CD71+ cells were detected in HPV-negative cervical cancer cells. Furthermore, ectopic expression of the HPV-E6 protein in HPV-negative C33A cells enriched the CD71+subpopulation. The CD71+ subpopulation isolated from the C33A cell line and an HPV-E6-overexpressing clone exhibited enhanced transforming ability, proliferation, and resistance to irradiation. In contrast, suppression of CD71 in HPV-positive SiHa cells and the HPV-E6-overexpressing stable clone inhibited spheroid formation and in vitro and in vivo tumorigenicity and sensitized cells to irradiation treatment. CRISPR/Cas9 knockout of CD71 in SiHa cells also produced similar inhibitory effects on tumorigenicity. Double knockout of CD71 and CD55 reversed the oncogenic properties of the HPV-E6-overexpressing clone. These findings suggest that the HPV-E6 protein enriches the subpopulation of CD71+cells in cervical cancer, which exhibit cancer stem-like cell properties and are resistant to irradiation treatment. Targeting the CD71+ subpopulation in cervical cancer cells with siRNAs or CRISPR/Cas9 may provide new insights for the development of novel therapeutic approaches for treating cervical cancer. IMPLICATIONS: We describe the enrichment of CD71+ population by HPV-E6 protein in cervical cancer cells that promotes cancer aggressiveness and resistance to irradiation treatment.

Abstract
Next-generation sequencing provides an opportunity to detect viral species from RNA-seq data of human tissues, but existing computational approaches do not perform optimally on clinical samples. We developed a bioinformatic method called VirTect for detecting viruses in neoplastic human tissues using RNA-seq data. Here, we used VirTect to analyze RNA-seq data from 363 head and neck squamous cell carcinoma (HNSCC) patients and identified 22 human papillomavirus (HPV)-induced HNSCCs. These predictions were validated by manual review of pathology reports on histopathologic specimens. VirTect showed better performance in recall and accuracy compared to the two existing prediction methods, VirusFinder and VirusSeq, in identifying viral sequences from RNA-seq data. The majority of HPV carcinogenesis studies thus far have been performed on cervical cancer and generalized to HNSCC. Our results suggest that carcinogenesis of HPV-induced HNSCC and other cases of HNSCC involve different genes, so understanding the underlying molecular mechanisms will have a significant impact on therapeutic approaches and outcomes. In summary, RNA-seq together with VirTect can be an effective solution for the detection of viruses from tumor samples and can facilitate the clinicopathologic characterization of various types of cancers with broad applications for oncology.

Abstract
Background To improve the targeting ability of antitumor drugs, we identified the antigens with high expression on the surface of tumor cells associated with tumor escape, such as the complement regulatory protein CD55 molecule, which is also known as the decay accelerating factor. In this study, phage display technology was used to screen and identify CD55-specific ligand peptide (CD55sp) bound to CD55 molecule on the surface of cervical cancer HeLa cells. We then explored the role of this peptide in inhibiting the growth of cervical cancer cells in vitro. Our characterization of CD55sp will provide implication for tumor target therapy. Methods The phage bound to the surface of HeLa cells were isolated by phage display technology. Positive phage clones were identified by ELISA. Phage was then amplified and determined by agarose gel electrophoresis after monoclonal DNA extraction. DNA sequencing and bioinformatical analysis were conducted to obtain specific ligand peptides. Flow cytometry and immunofluorescence were used to measure the expression of CD55 molecule on the surface of tumor and normal cells. Subsequently, the effects of CD55sp on the proliferation and apoptosis of HeLa and SiHa cells were determined by Cell Counting Kit-8 (CCK-8), flow cytometry, and TUNEL assay, respectively. The morphology of apoptotic cells was examined by electron microscope. The distribution of Cleaved caspase-3 was detected by immunofluorescence. The expression of bcl-2 and Cleaved caspase-3 were determined by Western blot. Results The results showed that the peptide (QVNGLGERSQQM) can bind to the CD55 molecule on the surface of cervical cancer HeLa and SiHa cells as a ligand peptide. It can also effectively inhibit the proliferation of cervical cancer cells and induce cell apoptosis. Conclusion This study demonstrates that CD55sp screened by phage display technology plays a strong antitumor role.
