Role of TAZ as mediator of Wnt signaling (MII)

ABSTRACT: To investigate the role of TAZ downstream of APC and beta-catenin in mammary epithelial cells cells, we compared the expression profiles of MCF10-T1k (MII) cells transfected with siControl, siAPC, siAPC+siTAZ, sibeta-catenin, or sibeta-catenin+siTAZ. Keywords: expression profiling by array

Role of TAZ as mediator of Wnt signaling (MII)

Project description:To investigate the role of TAZ downstream of APC and beta-catenin in mammary epithelial cells cells, we compared the expression profiles of MCF10-T1k (MII) cells transfected with siControl, siAPC, siAPC+siTAZ, sibeta-catenin, or sibeta-catenin+siTAZ. Keywords: expression profiling by array We collected RNA from MII cells transfected with siControl, siAPC, siAPC+siTAZ, sibeta-catenin, or sibeta-catenin+siTAZ. Cells were left untreated in normal culturing conditions before harvesting. Samples were then processed for total RNA extraction and hybridization on Affymetrix microarrays. Four biological replicas (A, B, C, D) were used for each of the 5 conditions (1: siControl, control cells; 2: siAPC cells; 3: siAPC+siTAZ cells; 4: sibeta-catenin (sibcat) cells; 5: sibeta-catenin+siTAZ) for a total of 20 samples.

Role of TAZ as mediator of Wnt signaling (SW480)

Project description:To investigate the role of TAZ downstream of the abberrant Wnt signaling in CRC cells, we compared the expression profiles of parental SW480 cells (empty vector) transfected with siControl, siTAZ, sibeta-catenin or reconstituted with wild type APC and transfected with siControl Keywords: expression profiling by array We collected RNA from parental SW480 cells (empty vector) transfected with siControl, siTAZ, sibeta-catenin or from SW480 cells reconstituted with wild type APC and transfected with siControl. Cells were left untreated in normal culturing conditions before harvesting. Samples were then processed for total RNA extraction and hybridization on Affymetrix microarrays. Four biological replicas (A, B, C, D) were used for each of the 4 conditions (1: siControl, control cells; 2: siTAZ cells; 3: sibeta-catenin (sibcat) cells; 4.APC reconstituted cells) for a total of 16 samples.

The effect of YAP/TAZ knockdown on the intestinal epithelium

Project description:The Hippo pathway plays a crucial in organ size control during development and tissue homeostasis in adult life. To examine a role for Hippo signaling in the intestinal epithelium, we analyzed gene expression patterns in the mouse intestinal epithelilum transfected with siRNAs or expression plasmids for shRNAs targeting the Hippo pathway effectors, YAP and TAZ. We performed two independent series of experiments (siGFP (n=3) vs siYAP/siTAZ (n=3), and shLacZ (n=1) vs shYAP/shTAZ (n=1)). Control siRNA (siGFP), YAP/TAZ siRNAs, or expression plasmids for control shRNA (shLacZ) or YAP/TAZ shRNAs were introduced into the mouse intestinal epithelium by the newly-developed in vivo transfection method. Four days after transfection, intestinal epithelial cells were isolated from the tissues and total RNA was extracted.

Cooperation of MYC and b-catenin in liver tumorigenesis requires Yap/Taz

Project description:One of the transcriptional targets of b-catenin/TCF and a key downstream effector of the WNT/b-catenin pathway in several tissues is the MYC proto-oncogene, which encodes for a transcription factor that is a master regulator of proliferation- and growth-related genes. However, several evidences indicate that this epistatic relationship does not seem to occur in liver: indeed Myc was not induced upon b-catenin activation driven by APC loss, and Myc deletion in hepatocytes does not suppress the effects of APC loss on cell proliferation and liver zonation. Besides, there are indications that the two pathways can be independently activated, and cooperate during tumorigenesis. In particular, MYC amplification and b-catenin mutations showed a tendency toward co-occurrence in either adult HCC or aggressive childhood hepatoblastoma, and MYC-driven HCC in experimental mouse models frequently acquired activating mutations in b-catenin. In order to address whether these observations reflect a functional cross-talk between the two pathways that may occur in a specific molecular subgroup of HCC patients, we generated a new mouse model allowing conditional activation of MYC and -catenin in hepatocytes. This model demonstrated a strong cooperativity between the two oncogenes in promoting liver tumorigenesis. Our data indicate that this cooperation occurs mainly through unrestrained proliferation of liver cells that requires the activity of the transcriptional co-factors Yap and Taz.
