ABSTRACT: To have a global picture of the miRNAs dependent on the transcription factor E2F1, we assessed small RNA changes, by RNA-sequencing, of HeLa cells transfected with an siRNA targeting E2F1 or a control siRNA.
Project description:Purpose: Next-generation sequencing (NGS) has revolutionized systems-based analysis of cellular pathways. The goals of this study are using RNA sequencing analysis to evaluate the effects of si-E2F1 (or E2F3) on the mRNA of human nasopharyngeal carcinoma cell line HK1. Methods: Human nasopharyngeal carcinoma cell line HK1 was transfected with a control non-targeting siRNA to cells or transfected with siRNA targeting E2F1 (or E2F3) for 48 hours in DMEM medium (with 10% serum). Total RNA were extracted and detected by Illumina high-throughput RNA sequencing data analysis. 3 independent biological replicates were plated, transfected in parallel for each control and siRNA. Results: Log-fold changes of up- or down-regulated mRNAs between the control and experiment group were selected with a significance threshold of p<0.05. Conclusions: Our study describes the mRNA changes of human nasopharyngeal carcinoma cell line HK1 transfected with E2F1 (or E2F3) siRNA.
Project description:We sequenced mRNA from cultured HeLa cells transfected with control or HNRNPU siRNA to compare gene expression level in PMA/Ca2+ ionophore stimulated condition
Project description:We have develped a novel method of making siRNAs (named pro-siRNA for prokaryotic siRNA). To evaluate off-targeting of pro-siRNA, we compared mRNA expression profile of HeLa-d1EGFP cells transfected with 4 nM LMNA siRNAs and pro-siRNAs by microarray.
