Developmental Cell (21)4 2011
Abstract
We use a combination of in vivo quantitative proteomics and analyses of cyclin E knockout mice to demonstrate that in terminally differentiated neurons cyclin E forms complexes with Cdk5 and controls synapse function by restraining Cdk5 activity. Ablation of cyclin E led to a decreased number of s...

Abstract
We have shown previously that the scaffold protein MEK1 partner (MP1) is localized to late endosomes by the adaptor protein p14. Using conditional gene disruption of p14 in livers of mice (p14(Δhep) ) we analyzed protein and transcript signatures in tissue samples. Further biological network analys...

Abstract
Knockout mice are used to study physiological function of the gene, while transgenic mice expressing a high level of the transgene are used to examine pharmacological action of the gene. Genes can be deleted not only in chondrocytes, but also at various steps during the process of chondrocyte differe...

Abstract
We aimed to develop a protocol for tamoxifen-induced gene inactivation with minimal effects on gene transcription and in vivo cardiac function, allowing studies of acute loss of the targeted gene. In mRNA microarrays, 35% of the 34,760 examined genes were significantly regulated in MCM(+/0) compared...

CBP/p300 double null cells reveal effect of coactivator level and diversity on CREB transactivation.
Abstract
We show that the number of CREB-binding sites (CREs) affects whether the related histone acetyltransferases (HATs) CREB-binding protein (CBP) and p300 are required for endogenous gene transcription. Fibroblasts with both CBP and p300 knocked-out had strongly attenuated histone H4 acetylation at CREB...

Abstract
We assessed whether TGF-alpha overexpression and TGF-beta signaling inactivation cooperate in hepatocarcinogenesis using an in vivo mouse model, MT1/TGFa;AlbCre/Tgfbr2(flx/flx) mice ("TGFa;Tgfbr2(hepko)"), which overexpresses TGF-alpha and lacks a TGF-beta receptor in the liver. TGF-beta signaling i...

Abstract
Retroviral integrases are vital enzymes in the viral life cycle and thus are important targets for antiretroviral drugs. The structure of the catalytic core domain of the integrase from human foamy virus, which is related to HIV-1, has been solved. The structure of the protein is presented in two di...

Abstract
Retroviral integrases associate during the early viral life cycle with preintegration complexes that catalyze the integration of reverse-transcribed viral cDNA into the host chromosomes. Several cellular and viral proteins have been reported to be incorporated in the preintegration complex. This stu...

Abstract
We determine the lineages of adult hematopoietic cells derived from Tie2-expressing populations using Tie2-Cre;Rosa26R-EYFP mice. In Tie2-Cre;Rosa26R-EYFP mice, analysis of bone marrow cells showed Cre-mediated recombination in 85% of the population. In adult bone marrow and spleen, we analyzed subc...

Abstract
We have previously generated a transgenic mouse strain (LSL-TβRI(CA)) containing a Cre-inducible constitutively active TGFβ type I receptor (Bartholin et al., 2008, Genesis 46: 724-731). Transgene expression depends on the excision of a floxed-transcriptional STOP (LSL, Lox-STOP-Lox) located upstr...

Abstract
We show that an LTR retrotransposon of ERV-9 human endogenous retrovirus located 40-70 kb upstream of the human fetal gamma- and adult beta-globin genes serves a long-range, host function. The ERV-9 LTR contains multiple CCAAT and GATA motifs and competitively recruits a high concentration of NF-Y a...

Abstract
We investigated ischemia-induced revascularization in mice that were deficient for LKB1 in Tie2-Cre-expressing cells. Whereas homozygous deletion of LKB1 led to embryonic lethality, heterozygous LKB1-knock-out (KO) (Lkb1(flox/+);Tie2(Tg/+)) mice were viable. Unchallenged heterozygous LKB1-KO mice di...

Abstract
We have generated a transgenic mouse line in which two conserved exons of the mouse intermediate dynein chain gene, Dnaic1, are flanked by loxP sites (Dnaic1(flox/flox)). Dnaic1 is the murine homolog of human DNAI1, which is mutated in approximately 10% of human PCD cases. These mice have been cross...

We have used Cre-lox fate mapping in transgenic mice to show that PDGFRA/NG2-expressing glia, a distributed population of stem/progenitor cells in the adult CNS, produce the remyelinating oligodendrocytes and almost all of the Schwann cells in chemically induced demyelinated lesions. In contrast, th...

Abstract
We therefore developed a direct integrase fusion protein strategy as an alternative way to package heterologous proteins into vectors. The method was tested by creating two different integrase fusion proteins, IN-p53 and IN-mCherry, cloned into the 3' end of pol in the packaging plasmid. Lentiviral...

Abstract
Most temperate phages encode an integrase for integration and excision of the prophage. Integrases belong either to the lambda Int family of tyrosine recombinases or to a subgroup of the serine recombinases, the large serine recombinases. Integration by purified serine integrases occurs efficiently...

Lentiviral vectors are a powerful tool for gene transfer into target cells in vitro and in vivo. However, there are concerns about safety with regard to their use in gene transfer protocols because of insertional mutagenesis following viral infection. Once in the target cells, and in addition to the...

We recently found that endogenous (free fatty acids) and pharmacological (thiazolidinediones) agonists of nuclear receptor Peroxisome proliferator-activated receptor (PPAR)gamma stimulate renin transcription. In addition, the renin gene was identified as a direct target of PPARgamma. The mouse renin...
