HOTAIR reprograms gene expression profiling in esophageal squamous cell carcinoma (ESCC) KYSE180 cells

Project description:To investigate the functional role of HOTAIR in esophageal squanmous cell carcinoma (ESCC) cells, RNAi-mediated knockdown of HOTAIR and overexpression of HOTAIR were carried out using KYSE180 cells. Gene expression microarray analysis revealed that a number of reported HOTAIR target genes were regulated by HOTAIR. Moreover, gene ontology analysis revealed enrichment of genes closely related to tumorigenesis, such as cell migration, regulation of cell cycles. For RNAi-mediated knockdown of HOTAIR, two different stealth siRNAs against HOTAIR were generated by Invitrogen, after which a mixture of the two was used for transfection. KYSE180 cells in 6-well plates were transfected with 100 pmol of Stealth siRNA (Invitrogen) or a Stealth RNAi Negative Control Medium GC (Invitrogen) using Lipofectamine2000 (Invitrogen). For HOTAIR overexpression, KYSE180 cells were transfected with LZRS_HOTAIR vector using Polyfect Transfection Reagent (Qiagen). Total RNA was extracted 48 h after transfection.

Gene expression signatures in GIST-T1 cells transfected with siRNA targeting HOTAIR

Project description:To analyze the effect of HOTAIR depletion in a gastrointestinal stromal tumor (GIST) cells, RNAi-mediated knockdown of HOTAIR was carried out using GIST-T1 cells. Gene expression microarray analysis revealed that a number of reported HOTAIR target genes were upregulated by knockdown of HOTAIR. Moreover, we found that 1424 genes were upregulated by siHOT (>2-fold), and Gene Ontology analysis revealed enrichment of genes related to “nucleus”, “chromosome” and “membrane-bounded organelle.” For RNAi-mediated knockdown of HOTAIR, three different Stealth siRNAs against HOTAIR were generated by Invitrogen, after which a mixture of the three was used for transfection. GIST-T1 cells in 6-well plates were transfected with 100 pmol of Stealth siRNA (Invitrogen) or a Stealth RNAi Negative Control Medium GC (Invitrogen) using Lipofectamine2000 (Invitrogen). Total RNA was extracted 48 h after transfection.

HOTAIR knockdown glioma cell proteomics

Project description:This study demonstrated the effects of lncRNA HOTAIR knockdown on the glioma proteomics. An abnormally high expression of the lncRNA HOTAIR has been previously demonstrated in glioma cells. HOTAIR regulates genes by anchoring epigenetic modification proteins and causes abnormalities in multiple signaling pathways. We knocked down HOTAIR in glioma cells by siRNA with SILAC labeling, and then total protein was extracted for proteome mass spectrometry.
