Effect of YAP overexpression on HuCCT1 cholangiocarcinoma cell line transcriptome (YAP overexpression)

ABSTRACT: The YAP pathway in regulating organ size by integrating external signals to control the expression of genes involved in cell proliferation. YAP is known to be involved in tumorigenesis in several tissues, yet its role in cholangiocarcinoma is not established We used microarrays to assess the role of YAP pathway in cholangiocarcinoma either by overexpressing a constitutively active YAP1 mutant, or by downregulating YAP1 expression using shRNA

YAP/TAZ-dependent transcriptome in cholangiocarcinoma cells

Project description:The Hippo pathway effectors yes-associated protein (YAP) and WW domain containing transcription regulator 1 (TAZ/WWTR1) support tumor initiation and progression in various cancer types. However, to which extent YAP and TAZ cooperatively contribute to cholangiocarcinoma (CCA) development and progression is poorly understood. Our immunohistochemical studies showed that YAP and TAZ were expressed in different CCA subtypes. However, nuclear co-expression was not frequently detected. RNAinterference (RNAi) experiments illustrated that YAP and TAZ supported CCA cell viability. Comprehensive expression profiling of HUCCT-1 cells after combined silencing of YAP/TAZ revealed a potential impact on chromosomal instability.

Gene expression changes caused by YAP overexpression and Nf2 deletion in the developing mouse brain

Project description:The transcriptional coactivator YAP is the key downstream effector of the Hippo pathway. YAP overexpression in the developing mouse brain results in excessive expansion of the neural progenitor pool and severe perturbation of brain development. Nf2/Merlin is a tumor suppressor whose mutations are found in many human cancers. Loss of Merlin during brain development causes overexpansion of the neural progenitor pool. We used microarrays to identify the gene expression changes caused by YAP overexpression and Nf2 deletion. We used a double-transgenic system to overexpress YAP in the developing mouse brain by crossing mice carrying a doxycycline-dependent allele of YAP1-S127A (TetO-YAP1) with those expressing the reverse tetracycline-dependent transactivator rtTA under the control of the neural progenitor-specific Nestin promoter (Nes-rtTA) and feeding the dam with doxycycline-containing food (200 mg/kg) from E7.5. We conditionally deleted Nf2 using the telencephalon-specific Emx1-Cre.

Yap reprograms glutamine metabolism to increase nucleotide biosynthesis and enable liver growth

Project description:The Hippo pathway is an important regulator of organ size and tumorigenesis. It is unclear, however, how Hippo signaling provides the cellular building blocks required for rapid growth. Here, we report that transgenic zebrafish expressing an activated form of the Hippo pathway effector Yap1 develop enlarged livers and are prone to liver tumor formation. Transcriptomic profiling reveals that Yap1 reprograms genes involved in glutamine metabolism. Analysis of gene expression in WT and lf:Yap transgenic zebrafish livers.
