Project description:The objective of the present study is to investigate the role of processing glycosidase inhibition induced by processing glycosidase inhibitors, namely castanospermin as the processing glucosidases inhibitor, deoxymannojirimycin as the processing mannosidases inhibitor, and deoxyfuconojirimycin as the fucosidase inhibitor. Comparative gene expression analysis was performed in human cervical carcinoma HeLa cells, with non-inhibitor-treated cells as the negative control. Gene expression was analyzed using 3D-Gene® Human 25k oligonucleotide microarrays and computational gene expression analysis tools. Inhibition of processing glycosidases (glucosidases, mannosidases, and fucosidase) in human cervical carcinoma HeLa cells was performed by treating with a small molecule inhibitor and then culturing at 37°C. Total RNA samples were prepared from the cells. Gene expression was analyzed using 3D-Gene® Human 25k oligonucleotide microarrays. Sample preparation for array hybridization was carried out as described in the manufacturer's instructions.

Project description:Cervical cancer is the one of the most prevalent types of cancers in women and is the second highest cause of death in women aged 20-39. The most common chemotherapy for cervical cancer involves the use of the drug cisplatin in conjunction with other therapeutics. However, the development of cisplatin resistance in patients can hinder the efficacy of these treatments. This highlights the need to explore different therapeutic approaches for cervical cancer treatment. We found that inhibitors targeting the enzyme Poly (ADP-ribose) Polymearse (PARP)-1 can attenuate cell growth of cervical adenocarcinoma and squamous cell carcinoma. Furthermore, combinatorial therapy of PARP inhibitors (PARPi) with cisplatin increases the cisplatin-mediated cell toxicity in cervical cancer cells. This is accompanied by a rewiring of the transcriptome in response to the cisplatin and PARPi together. Surprisingly, we observed that the Fos gene is upregulated in the dual treatment condition leading to the subsequent induction of its target genes. Importantly, increased the expression of Fos is sufficient to hinder cervical cancer growth. We conclude that by inducing Fos expression, PARPi treatment with cisplatin leads to inhibition of cervical cancer.

Project description:To explore the transcriptional inhibition of the CDK7 inhibitor THZ1 in cervical cancer cells, we used gene expression miceoarray analysis to detect the gene expression profiles after THZ1 treatment in HeLa compared with negative control（DMSO）. HeLa was trreated with 100 nM THZ1 or DMSO, and total RNA was extracted after treatment for 6 hours. Microarray analysis showed that massive oncogene transcripts, especially those associated with tumorigenesis, were preferential suppressed after THZ1 treatment.

Project description:Background and Purpose: Our previous work reported that galaxamide, a cyclopeptide extracted from the seaweed Galaxaura filamentosa, showed antiproliferative activity against HeLa cells by MTT assay. However, the therapeutic effects in vivo and potential mechanisms to eliminate cervical cancer cells remain unknown. Experimental Approach: HeLa cells were obtained as a cervical carcinoma in vitro model. The growth-inhibitory effects of galaxamide in HeLa cells and xenograft mouse models were investigated. RNA-seq was employed to analyse the main target of galaxamide in HeLa cells. Immunostaining, qRT‒PCR and Western blotting were applied to test the pharmacological effects in vitro and in vivo. Key Results: Galaxamide significantly inhibited cell growth, colony formation, migration, and invasion and induced cell apoptosis by inhibiting the Wnt signalling pathway in HeLa cells. RNA sequencing revealed that galaxamide regulated stemness via the Wnt6 signalling pathway in HeLa cells. By analysing The Cancer Genome Atlas database (TCGA), Wnt6 was found to be negatively/positively correlated with stemness- and apoptosis-related genes in human cervical cancer. Cancer stem-like cells (CSCs) isolated and enriched from HeLa cells demonstrated elevated Wnt6 and β-catenin genes compared with nonstem HeLa cells. After galaxamide treatment, CSCs showed abrogation of sphere-forming ability, along with inhibition of stemness-related and Wnt pathway genes. Galaxamide treatment was accompanied by the induction of apoptosis in HeLa cells, which was consistent with the results in BALB/c nude mice. Conclusion and Implications: Our results provide preclinical evidence that suppression of stemness by downregulating the Wnt signalling pathway is the molecular mechanism by which galaxamide effectively inhibits cell growth and induces apoptosis in cervical cancer cells.

Project description:FSCN1 has been reported to be dysregulated in cervical cancers. However, the genome-wide regulated targets of FSCN1 is still unclear in cervical cancers. Here, the gene expression profile of HeLa cells transfected with FSCN1 shRNA (shFSCN1) were compared with cells transfected with empty vector (shCtrl). The results showed that shFSCN1 extensively affects the transcriptional level of 5, 043 genes in HeLa cells. There were more up-regulated genes (3, 870) than down-regulated ones (1, 173) after FSCN1 was knocked down in HeLa cells. GO analysis showed that the up-regulated genes were associated with transcription regulation and DNA binding. The down-regulated genes were enriched in some cancer associated pathway including angiogenesis and cell adhesion. In particular, FSCN1 positilvely regulated ANGPTL4 in HeLa cells. Compared to normal tissue, both FSCN1 and ANGPTL4 showed a higher expression in cervical tumor tissue. Moreover, ANGPTL4 was also positilvely correlated with expression of FSCN1 in cervical tumor tissue of TCGA. In conclusion, our study provide important cues for further study on the regulatory mechanism of FSCN1 in cervical cancer.

Project description:MicroRNAs (miRNAs or miRs) play essential roles in the initiation and progression of human tumors, including cervical cancer. However, the mechanisms underlying their actions in cervical cancer remain unclear. The present study aimed to evaluate the functional role of miR‑130a‑3p in cervical cancer. Cervical cancer cells were transfected with a miRNA inhibitor (anti‑miR‑130a‑3p) and a negative control. Adhesion‑independent cell proliferation, migration and invasion were evaluated. The findings presented herein demonstrated that miR‑130a‑3p was overexpressed in HeLa, SiHa, CaSki, C‑4I and HCB‑514 cervical cancer cells. The inhibition of miR‑130a‑3p significantly reduced the proliferation, migration and invasion of cervical cancer cells. The canonical delta‑like Notch1 ligand (DLL1) was identified as a possible direct target of miR‑103a‑3p. The DLL1 gene was further found to be significantly downregulated in cervical cancer tissues. On the whole, the present study demonstrates that miR‑130a‑3p contributes to the proliferation, migration and invasion of cervical cancer cells. Therefore, miR‑130a‑3p may be used as a biomarker to determine cervical cancer progression.

Project description:We performed gene expression profiling with oligonucleotide microarrays of hydrogen-bond surrogate targheting hypoxia-inducibletranscription factior complex, which resulted in an effective inhibition of hypoxia-inducible genes with relatively minimal perturbation of non-targeted signaling pathways. Hypoxic HeLa cells were treated with transcriptional inhibitors HBS 1, HBS 2 or vehicle and their expression profiles were compared to normoxic HeLa cells

Project description:KMT2B，a major H3K4 tri-methyltransferase, contributes to the development of various cancers. However, its role in cervical cancer is unclear. We found that KMT2B is upregulated in cervical cancer tissues, which is significantly associated with poor prognosis.To investigate the underlying mechanism of KMT2B in the progression of cervical cancer, we established stable KMT2B-overexpression HeLa cells.Then we compared the whole genome mRNA expression profile of KMT2B overexpression and control HeLa cells using RNA-seq.
