MARCKS protein is transcriptionally down-regulated in v-Src-transformed BALB/c 3T3 cells.

Activation of protein kinase C (PKC) by tumor-promoting phorbol esters leads to the phosphorylation of an 80-kilodalton PKC substrate (known as MARCKS) in murine fibroblasts. In BALB/c 3T3 cells stably transformed by v-Src, phorbol esters were unable to induce phosphorylation of MARCKS. Western blot analysis and in vitro kinase assays showed that both PKC protein levels and kinase activity were...

Expression of a protein tyrosine phosphatase in normal and v-src- transformed mouse 3T3 fibroblasts

A rat cDNA encoding a 51-kD protein tyrosine phosphatase (PTP1) was cloned into a mammalian expression vector and transfected into normal and v-src-transformed mouse NIH 3T3 fibroblasts. In the stable subclones isolated, PTP1 expression at the mRNA level was elevated twofold to 25-fold. The highest constitutive level of phosphotyrosine-specific dephosphorylating activity observed without cytoto...

Pleiotropic action of AP-1 in v-Src-transformed cells.

The activation of AP-1 is a hallmark of cell transformation by tyrosine kinases. In this study, we characterize the role of AP-1 proteins in the transformation of chicken embryo fibroblasts (CEF) by v-Src. In normal CEF, the expression of a dominant negative mutant of c-Jun (TAM67) induced senescence. In contrast, three distinct phenotypes were observed when TAM67 was expressed in v-Src-transfo...

cdc42-interacting protein 4 gene is down trans-regulated by hbv dna polymerase trans activated protein 1.

hepatitis b virus (hbv) dna polymerase transactivated protein 1 (hbvdnaptp1) is a novel protein transactivated by hbv dna polymerase, screened by suppression subtractive hybridization technique (genbank accession no: ay450389). the biological function of hbvdnaptp1 was investigated in this study.we constructed a vector pcdna3.1 (-)/myc-his a-hbvdnaptp1 and used it to transfect acute monocytic l...

Adipsin gene expression in 3T3-F442A adipocytes is posttranscriptionally down-regulated by retinoic acid.

Retinoic acid (RA) has been shown to inhibit the differentiation of 3T3 adipogenic cell lines. In this report, the steady-state levels of several adipose-specific mRNAs were studied in mature adipocytes treated with RA. Northern blot analysis showed that, following a 24-h exposure of 3T3-F442A adipocytic cultures to RA (10 microM), there was a 4-5-fold decrease of adipsin mRNA level. In contras...
