Figure Legend Snippet: Suppression of LRH-1 in HepG2 prevents its growth and colony formation capacity in vitro. Notes: ( A ) Schematic diagram of the TALENs targeting the second exon of LRH-1 and Western blotting (WB) validation of HepG2 LRH-1/− cell clones. ( B ) Proliferation assay by MTT. Two HepG2 LRH-1/− cell clones proliferated at slower rates than the parental HepG2 cells. ( C ) Colony formation assay. Results showed that HepG2 LRH-1/− cells formed smaller and less colonies than parental HepG2 cells. ** P <0.01 vs parental HepG2 cells. Abbreviation: TALENs, transcription activator-like effector nucleases.
Techniques Used: In Vitro, TALENs, Western Blot, Biomarker Discovery, Clone Assay, Proliferation Assay, Colony Assay
Figure Legend Snippet: Suppression of LRH-1 in HepG2 attenuates its growth in vivo. Notes: ( A and B ) Growth curve shows the growth patterns of tumors formed by HepG2 LRH-1/− cell clones and parental HepG2 cells, HepG2 cells formed xenograft tumors with larger sizes and at faster rates as compared to HepG2 LRH-1/− #1 cells, while HepG2 LRH-1/− #2 lost the in vivo tumorigenic capacity in all nude mice (NT, no tumor). ( C ) Ki67 immunohistochemistry. Our results suggested that significantly lower and less Ki67 immunoreactivity was seen in xenograft tumors formed from HepG2 LRH-1/− than parental HepG2 cells. Scale bar =100 μm.** P <0.01 vs parental HepG2 cells.
Techniques Used: In Vivo, Clone Assay, Immunohistochemistry
Figure Legend Snippet: Gene expression microarray analysis for the identification of LRH-1-regulated genes in HepG2 cells. Notes: ( A ) Gene ontology (GO) analysis of genes that are LRH-1-regulated in HepG2 and in HepG2 LRH-1/− cells. ( B ) KEGG pathway enrichment analysis for LRH-1-regulated genes in HepG2 cells are shown. ( C ) Several cell cycle-related genes that altered after suppression of LRH-1 were listed. Abbreviations: BP, biological process; DE, differential expression; KEGG, Kyoto Encyclopedia of Genes and Genomes.
Techniques Used: Gene Expression, Microarray, Quantitative Proteomics
Figure Legend Snippet: LRH-1 promotes the development and progression of HCC through induction of c-myc and cyclin E1, and suppression of p21. Notes: ( A ) qRT-PCR analysis of c-myc, cyclin E1, and p21 genes in HepG2 and HuH-7 cells with ectopic LRH-1 expression. Our data indicated that ectopic expression of LRH-1 dramatically induced the mRNA and protein levels of c-myc and cyclin E1, and attenuated, in the meanwhile, the expression of p21. ( B ) Western blotting validation of c-myc, cyclin E1, and p21 in HepG2 and HuH-7 with ectopic LRH-1 expression. ( C ) Reporter assay showed that luciferase activity of c-myc and cyclin E1 promoter-luc reporter was significantly enhanced, while that of p21 was dramatically suppressed, in HepG2-LRH-1 cells. ( D ) MTT results indicated that the increased growth ability of HepG2-LRH-1 cells could be, at least partially, reversed by suppressing the expression of c-myc or restoring the expression of p21. ( E ) Schematic diagram showing the hypothesized pathways of LRH-1-mediated cell growth in HCC via its transcriptional repression of p21 and transactivation of c-myc and cyclin E1. * P <0.05; ** P <0.01; # not significant. Abbreviations: HCC, hepatocellular carcinoma; luc, luciferase.
Techniques Used: Quantitative RT-PCR, Expressing, Western Blot, Biomarker Discovery, Reporter Assay, Luciferase, Activity Assay
