Project description:γKlotho is critical for the survival of triple negative breast cancer (TNBC) cells HCC1395, since its depletion leads to decreased cell viability, cell cycle arrest and apoptosis. Here, we compare γKlotho knockdown cells with control HCC1395 cells at gene expression level in order to get insight into the possible cellular mechanisms contributing to the sensitivity of TNBC cells to γKlotho depletion.
Project description:Purpose: Gene expression analysis of knockdown and overexpression of LBH (Limb-Bud-and-Heart) in human breast cancer cell lines using RNA-Seq Methods: RNA was collected and analyzed from three biological replicates of each condition (LBH vs vector) for LBH overexpression (OE) in two human breast cancer cell lines (BT549, MCF7). Additionally, RNA was collected and analyzed from three biological replicates of each condition (siLBH vs non-target/NT siRNA) for LBH knockdown (KD) in two human triple negative breast cancer cells lines (HCC1395, MDA-MB-231). High-throughput sequencing used Illumina platforms. Results: Using an optimized data analysis workflow, we mapped about 60 million sequence reads per sample to the human genome (build hg19). Conclusions: Our study represents the first gene profiling analysis of LBH transcriptomes in human breast cancer cell lines, with biologic replicates, generated by RNA-seq technology.
