A subtractive cloning procedure was used to characterize the molecular changes involved in transformation of normal myoblasts to rhabdomyosarcoma (RMS) cells. Here we describe the cloning of DRAL, a… (More)
The calcium-binding protein S100A2 is expressed in normal breast tissue but downregulated during breast cancer progression. Hence it was previously identified as a candidate tumor suppressor gene. In… (More)
The p42/p44 mitogen-activated protein kinase (MAPK) cascade includes Ras, Raf, Mek, and Erk MAPK. To determine the effect of a full knockout at a single level of this signaling pathway in mammals,… (More)
Deregulated expression of the transcription factor PAX3 was observed previously in several tumors like rhabdomyosarcoma and Ewing's sarcoma. Because PAX3 expression is also found in pluripotent… (More)
Erk1/2 mitogen-activated protein kinases (MAPKs) are often hyperactivated in human cancers, where they affect multiple processes, including proliferation. However, the effects of Erk1/2 loss in… (More)
DRAL is a four and a half LIM domain protein identified because of its differential expression between normal human myoblasts and the malignant counterparts, rhabdomyosarcoma cells. In the current… (More)
The regulation of acute-phase protein production and nitric oxide (NO) release in lipopolysaccharide-induced liver injury is thought to occur in response to monocytes/macrophages and… (More)
Using a subtractive hybridization method, we have cloned 48 cDNAs which are expressed in human primary myoblasts but down-regulated in the embryonal-rhabdomyosarcoma (RMS) cell line RD. Twenty-nine… (More)
To elucidate mechanisms of cancer progression, we generated inducible human neoplasia in three-dimensionally intact epithelial tissue. Gene expression profiling of both epithelia and stroma at… (More)
Cell transformation is often a result of constitutive activation of genes in signaling pathways that regulate cell proliferation and differentiation. Indeed, the Ras/Raf/MEK/ERK mitogen-activated… (More)
