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

ABSTRACT: 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 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 a miR-335 mimic molecule

Project description:To clarify the effect of miRNAs, we carried out a gene expression microarray analysis using GIST-T1 cells transfected with a miR-335 mimic or a negative control. We found that 1,095 probe sets (853 unique genes) were downregulated (>1.5-fold) by ectopic miR-335 expression. GIST-T1 cells were transfected with a mirVana miR-335 mimic (Ambion) or a mirVana miRNA mimic Negative Control #1 (Ambion). Forty-eight hours after transfection, total RNA extraction was carried out, and gene expression signatures were analyzed.

Gene expression signatures in GIST-T1 cells transfected with a miR-34a mimic molecule

Project description:To clarify the effect of miRNAs, we carried out a gene expression microarray analysis using GIST-T1 cells transfected with a miR-34a mimic or a negative control. We found that 2,621 probe sets (1,933 unique genes) were downregulated (>1.5-fold) by ectopic miR-34a expression, including PDGFRA gene which was previously reported as a miR-34a target gene. GIST-T1 cells were transfected with a mirVana miR-34a mimic (Ambion) or mirVana miRNA mimic Negative Control #1 (Ambion). Forty-eight hours after transfection, total RNA extraction was carried out, and gene expression signatures were analyzed.

Kinome Profiling of Gastrointestinal Stromal Tumors Using Multiplexed Inhibitor Beads and Mass Spectrometry Identifies Wee1 as a Candidate Therapeutic Target

Project description:Purpose: Management of gastrointestinal stromal tumor (GIST) has been revolutionized by the identification of activating mutations in KIT and PDGFRA and the clinical application of receptor tyrosine kinase (RTK) inhibitors in the advanced disease setting. Stratification of GIST into molecularly defined subsets provides insight into clinical behavior and response to approved targeted therapies. Although these RTK inhibitors are effective in the majority of GIST, resistance to these agents remains a significant clinical obstacle. Development of effective treatment strategies for refractory GIST requires identification of novel targets to provide additional therapeutic options. Global kinome profiling has the potential to identify critical signaling networks and reveal protein kinases that are essential in GIST. Experimental Design: Using Multiplexed Inhibitor Beads and Mass Spectrometry paired with a super-SILAC kinome standard, we explored the majority of the kinome in GIST specimens from three GIST subtypes (KIT-mutant, PDGFRA-mutant and succinate dehydrogenase-deficient GIST) to identify novel kinase targets. In vitro and in vivo studies were performed to evaluate the utility of targeting the identified kinases in GIST. Results: Kinome profiling revealed distinct signatures in three GIST subtypes. PDGFRA-mutant GIST had elevated tumor associated macrophage (TAM) kinases and immunohistochemical analysis confirmed increased TAMs present in these tumors. Kinome profiling with loss-of-function assays revealed a significant role for G2-M tyrosine kinase, Wee1, in GIST survival. In vitro and in vivo studies revealed significant efficacy of MK-1775 (Wee1 inhibitor) in combination with avapritinib in both KIT and PDGFRA-mutant GIST cell lines, as well as notable efficacy of MK-1775 as a single agent in the PDGFRA-mutant line. Conclusions: These studies provide strong preclinical justification for the use of MK-1775 in GIST.

ETV1 knockdown in GIST cell lines

Project description:ETV1 is highly expressed in GIST cells and required for their survival and growth. To identify genes and pathways regulated by ETV1 in GIST, we performed expression profiles of GIST cells after ETV1 knockdown. Two GIST cell lines (GIST48 and GIST882) were infected in duplicate with three shRNA viruses (Scrambled, ETV1sh1-B11TRCN0000013923, ETV1sh2-TRCN0000013925). Four days after infection, RNA was harvested for expression profiling.
