Expression profiling in primary embryonic fibroblasts deficient for the N-terminal truncation of Lats1

Project description:Lats1 and Lats2 are the mediators of the Hippo pathway that regulates tissue growth and proliferation. Lats1 and Lats2 kinases share 85% sequence identity in the kinase domain. However, their non-kinase regions at the N-terminus are distinct except for Lats conserved domain 1 (LCD1) and LCD2, suggesting that their N-terminal regions are important for Lats1/2-specific functions. In this study, we generated Lats1 knockout mice disrupting the N-terminal region containing LCD1 (Lats1M-NM-^TN/M-NM-^TN). We show that some Lats1M-NM-^TN/M-NM-^TN mice were born safely and grew normally. However, mouse embryonic fibroblasts (MEFs) from Lats1M-NM-^TN/M-NM-^TN mice displayed drastic defects in mitosis, showing enhanced centrosome overduplication, chromosomal misalignment, multipolar spindle formation, chromosome bridging, and cytokinesis failure. Moreover, they displayed accelerated cell cycle and cell growth bypassing a cell-cell contact inhibition like tumor cells, and exhibited anchorage independent growth. Indeed, Lats1M-NM-^TN/M-NM-^TN MEFs produced tumors in nude mice after subcutaneous injection, although the tumor growth rate was much slower than ordinary cancer cells. Furthermore, Yap, the key transcriptional co-activator in the Hippo pathway, was overexpressed and retained stable in Lats1M-NM-^TN/M-NM-^TN MEFs under high cell density, and expression of Lats2 mRNA were down-regulated. Total RNAs were extracted from MEFs under high or low cell density using miRNeasy extraction kit (Qiagen). A Dye-swapped experiment was performed by hybridizing complimentary RNA (cRNA) labeled with either Cyanine (Cy) -3 or Cy-5 (Perkin-Elmer) onto Whole Mouse Genome Oligo Microarray (G4122F; Agilent Technologies). Co-hybridizations were performed and data from Cy3 or Cy5 channels were analyzed as normalized signal intensities rather than as log ratios corresponding to each array.

Transcription profiling of rat adrenal glands from normoxic and hypoxic neonatal animals

Project description:We hypothesize that changes in adrenal gene expression mediate the increased plasma corticosterone and steroidogenesis in rat pups exposed to hypoxia from birth. Experiment Overall Design: In the current study, rat pups (with their dams) were exposed to hypoxia from birth and compared to pups from normoxic dams fed ad libitum. Adrenal glands were collected from normoxic and hypoxic pups at PD7and pooled (N=24/sample; 4 samples per treatment group) for total RNA extraction. Microarray analysis was performed, followed by verification with real-time PCR. Furthermore, the expression of selected genes involved in adrenal function was analyzed by real-time PCR, regardless of microarray results.

Gene expression profile in the small Maf-deficient livers.

Project description:To elucidate the functional roles of sMafs in the adult liver, we conditionally targeted the sMaf genes using a transgenic complementation rescue approach. MafF-/-::MafG-/-::MafK-/- (F0G0K0) mice are embryonic lethal but can be rescued by complementation of transgenic MafG expression under the regulation of the MafG regulatory domain (MGRD). Therefore, we rescued F0G0K0 mice using a MGRD transgenic mouse line with a MafG gene flanked with loxP (fMafG) sequences so that the MafG gene could be deleted by Cre-mediated recombination. The Albumin(Alb)-Cre transgenic mice were used to delete fMafG gene specifically in the liver. The genotype used are MafF-/-::MafG-/-::MafK-/-::MGRD-fMafG::Alb-Cre (liver-specific sMaf CKO) and MafF-/-::MafG+/-::MafK-/-::MGRD-fMafG::Alb-Cre (control).
