Long non-coding RNAs are differentially expressed in hepatocellular carcinoma cell lines with different metastatic potential

ABSTRACT: We describe the lncRNA expression profiles of two HCC cell lines, one with high potential for metastasis to the lung (HCCLM3) and the other to lymph nodes (HCCLYM-H2). The HCCLM3(LM3) and HCCLM6 cell lines were derived from the same parental cell line MHCC-97H. LM3 metastasizes to the lung, while HCCLM6 can metastasize to multiple organs in a mouse model. By subcloning HCCLM6, we established the HCCLYM-H2(H2) cell line, which showed stable and high metastatic potential specific to the lymph nodes. In the present study, we compared the expression profiles of HCC cell lines with a similar genetic background but different potential for lung or lymph node metastasis. We found that expression signatures comprising lncRNAs and protein-coding mRNAs were significantly associated with organ-specific HCC metastasis. To further validate microarray data, we selected six lncRNAs (CR613944, BC058547, RP5-1014O16.1, NCRNA00173, lincRNA-CALCA, lincRNA-TSPAN8) and two mRNAs (TSPAN8, CALCB) in the two HCC cell lines using qRT-PCR. Data obtained from qRT-PCR and the microarray was consistent.

Data obtained from qRT-PCR and the microarray was consistent. Differentially expressed lncRNAs between high lymphatic metastatic potential HCC cell H2 and high lung metastatic potiential HCC cell LM3 were identified by microarray and validated using quantitative real-time polymerase chain reaction.

MALAT1 (metastasis-associated lung adenocarcinoma transcript 1) Human HCC proteomics

Project description:The long noncoding RNA MALAT1 (metastasis-associated lung adenocarcinoma transcript 1), also known as MALAT-1 or NEAT2 (nuclear-enriched abundant transcript 2), is a highly conserved nuclear noncoding RNA (ncRNA). Two molecular functions of MALAT1 have been proposed, one is the control of alternative splicing and the other is the transcriptional regulation. To uncover its function in HCC, we knock down it in human HCC LM3 cell lines, and profiling the sample with LC/MS/MS and RNA sequencing.

Gene expression of three hepatocellular carcinoma cell lines with different organ-tropism.

Project description:In this study we investigated the gene expression profiling in three HCC cell lines with different organ-tropism.The parent cell line has low metastasis ability in nude mice model. Subclone 1 has higher metastasis ability specific to lung, and subclone 2 has dual metastasis ability to lung and celiac lymph node. We aimed to explore differentially expressed genes involved in process of HCC metastasis and organ-specific metastasis, and identify their biological functions. Examination of different gene expression among the 3 cell types.

Microarray analysis of exosomal miRNAs from different liver cancer cells

Project description:To explore how tumor-derived exosomes activate fibroblasts and foster lung metastasis of liver cancer. MiRNAs encapsulated in exosomes are abundant and play an important role in cell-cell communication. Therefore, we hypothesized that tumor-derived exosomal miRNAs mediate fibroblasts activation. To identify the specific miRNAs involved, we conducted microarrays to generate miRNAs profiles of exosomes derived from the four liver cancer cell lines with different migration and invasion abilities. CSQT-2 and HCC-LM3 cells were high metastatic cancer cells, versus to HepG2 and MHCC-97L cells. We divided them into the following groups: CSQT-2 versus HepG2 (with different origins), HCC-LM3 versus MHCC-97L (with the same origin) and compared the up-regulated miRNAs in both two high-metastatic cancer cells-derived exosomes. Then, these up-regulated miRNAs were subjected to validation to define the most important exosomal miRNAs in regulating fibroblast activation and contributing to lung metastasis of liver cancer.

Pulmonary metastasis in xenograft model after orthotopic implantation

Project description:Metastasis is a major factor for mortality in patients with hepatocellular carcinoma (HCC). Thus, there is a need for predictive biomarker(s) for detecting the tipping point before metastasis, so as to prevent further deterioration. To discover early warning signals of pulmonary metastasis in HCC, we analysed time-series gene expression data in the spontaneous pulmonary metastasis mouse HCCLM3-RFP model with our novel dynamic network biomarker (DNB) method. To simulate tumour growth and metastasis in patient livers, we used the spontaneous pulmonary metastasis mouse model, HCCLM3-RFP, which involves the orthotopic transplanted human HCCLM3 cell line labelled with a stable fluorescent protein.We observed that, hepatic tumours in orthotopic xenograft HCCLM3-RFP mice grew gradually from the second to the fifth week after orthotopic implantation in the primary liver tissue, whereas spontaneous pulmonary metastasis occurredonly at the last time point (the fifth week after orthotopic implantation).Thus, we chose the second, third, fourth, and fifth weeks after orthotopic implantation as observation points to collect liver tumours of five orthotopic xenograft mice at each time point and to assess the whole-genome expression.

LncRNA regulated by hnRNPAB in HCC cell lines

Project description:To reveal the HNRNPAB-regulated lncRNAs, we performed microarray analyses to screen differential lncRNAs in HCC cells after stable overexpression or knockdown of HNRNPAB. MHCC97H and HCCLM3 (HCC cell lines with high-metastatic potentials), PLC/PRF/5 and HepG2 (HCC cell lines with low-metastatic potentials) were used in this study. HepG2-control, HepG2-hnRNPAB, PLC/PRF/5-control, PLC/PRF/5-hnRNPAB, MHCC97H-control, MHCC97H-sh-hnRNPAB, HCCLM3-control, HCCLM3-sh-hnRNPAB were perpared with hU6-MCS-CBh-gcGFP-IRES-puromycin-shRNA-HNRNPAB/mock lentiviral and Ubi-MCS-SV40-EGFP-IRES-puromycin-HNRNPAB/mock cDNA lentiviral,respectively, each performed in triplicate.
