NAT10-mediated RNA acetylation enhances HNRNPUL1 mRNA stability to contribute cervical cancer progression.

Project description:N4-acetylcytidine (ac4C) is a lately discovered nucleotide modification that has been shown to be closely implicated in cancer. N-acetyltransferase10(NAT10) acts as an enzyme that regulates mRNA acetylation modifications. Currently, the role of NAT10-mediated RNA acetylation modification in cervical cancer remains to be elucidated. On the basis of transcriptome analysis of TCGA and GEO open datasets (GSE52904, GSE29570, GSE122697), NAT10 is upregulated in cervical cancer tissues and correlated with poor prognosis. Knockdown of NAT10 suppressed the cell proliferation, invasion, and migration of cervical cancer cells. The in vivo oncogenic function of NAT10 was also confirmed in xenograft models. Combined RNA-seq and acRIP-seq analysis revealed HNRNPUL1 as the target of NAT10 in cervical cancer. NAT10 positively regulate HNRNPUL1 expression by promoting ac4C modification and stability of HNRNPUL1 mRNA. Furthermore, depletion of HNRNPUL1 suppressed the cell division, invasion, and migration of cervical cancer. HNRNPUL1 overexpression partially restored cellular function in cervical cancer cells with NAT10 knockdown. Thus, this study demonstrates that NAT10 contributes to cervical cancer progression by enhancing HNRNPUL1 mRNA stability via ac4C modification, and NAT10-ac4C-HNRNPUL1 axis might be a potential target for cervical cancer therapy.

Microarray expression profile and functional analysis of circular RNAs in cervical cancer

Project description:Five human cervical cancer cell lines (HeLa, CaSki, SiHa, C-33A, SW756) and one human normal cervical epithelial cell line HcerEpic were included in the study. Microarray based circRNA expression profiles were acquired using the Arraystar Human circRNA Array (8x15K, Arraystar). We identified circRNAs differentially expressed in human cervical cancer cell lines compared to human normal cervical epithelial HcerEpic cells (control).

Microarray expression profile of circular RNAs in cervical cancer

Project description:Human immortal cervical cell line H8, human cervical cancer cell line SiHa and SiHa transfected with Wnt11-overexpression vector were included in the study. We identified circRNAs differentially expressed between H8 and SiHa or between SiHa and SiHa transfected with OV-Wnt11.

Epigenetic treatment of cervical carcinoma cell lines

Project description:Four cervical carcinoma cell lines (C4I, CaSki, HeLa, SiHa) were treated with epigenetic modifying drugs 5-aza-2’-deoxycytidine and trichostatin A. Such treatment leads to reactivation of genes that are epigenetically silenced in cancer by aberrant methylation; reactivated genes were then identified by microarray profiling. Subsets consist of 2 biological repeats and 2 dye-flip experiments for each repeat for CaSki cell line, and 3 repeats, each with 2 dye-flip experiments for C4I, HeLa, Caski cell lines. The identification of reactivated genes, their selection for validation experiments, and final identification of 6 genes that are significantly more often hypermethylated in cervical carcinoma clinical specimens is described in (manuscript submitted).

Quantitative proteomic study of two cervical cancer cell lines upon re-expression of Galectin 7

Project description:Galectin-7 expression was found to be strongly reduced in cervical cancer cell lines. The same tumor cell lines in which Galectin-7 was ectopically expressed exhibited significant decrease in their tumorigenic capacity in vitro and in vivo. The proteomic changes in the cervical cancer cell lines HeLa and SiHa after Galectin-7 re-expression were here quantified by SILAC.

MicroRNA analysis in HPV-positive and HPV-negative cervical cancer cell lines

Project description:Persistent infection by high-risk human papillomaviruses (HPVs) is associated with the development of cervical cancer and a subset of anogenital and head and neck squamous cell carcinomas. Abnormal expression of cellular microRNAs (miRNAs) plays an important role in the development of cancer, including HPV-related tumors. MiRNA expression profile was investigated by microrray analysis in the HPV-positive cervical cancer cell lines SiHa (HPV16-positive cell line derived from a cervical squamous cell carcinoma), CaSki (HPV16-positive cell line derived from a metastatic cervical epidermoid carcinoma), and HeLa (HPV18-positive cell line derived from a cervical adenocarcinoma) and compared with primary HFKs and C33a (HPV-negative cervical cell line).

MicroRNA‑130a‑3p inhibition suppresses cervical cancer cell progression

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.

Knock down of FTO in cervical cancer cells

Project description:FTO, an N6-methyladenosine (m6A) demethylase, can promote cervical cancer cell proliferation and migration. RNA-sequencing of SiHa cells with FTO knockdown was conducted to dissect the differentially expressed genes and the potential mechanism of FTO in cervical cancer.
