Phosphorylation regulates transcriptional activity of PAX3/FKHR and reveals novel therapeutic possibilities

Inhibition of constitutive active signaling pathways, which are a characteristic phenomenon for many tumors, can be an effective therapeutic strategy. In contrast, oncogenic transcription factors, often activated by mutational events, are in general...

Slit-2 induces a tumor suppressive effect by regulating beta -catenin in breast cancer cells

SLIT-2 is considered as a candidate tumor suppressor gene (TSG) since it is frequently inactivated in various cancers due to hypermethylation of its promoter region and allelic loss. However, the exact mechanism of its tumor suppressive effect has...

Multiple Cellular Mechanisms Related to Cyclin A1 in Prostate Cancer Invasion and Metastasis

BACKGROUND: Cyclin A1 is a cell cycle regulator that has been implicated in the progression of prostate cancer. Its role in invasion and metastasis of this disease has not been characterized. METHODS: Immunohistochemistry and cDNA microarray analyses...

A role for cytoplasmic PML in cellular resistance to viral infection

PML gene was discovered as a fusion partner with retinoic acid receptor (RAR) alpha in the t(15:17) chromosomal translocation associated with acute promyelocytic leukemia (APL). Nuclear PML protein has been implicated in cell growth, tumor...

HDAC6 is a specific deacetylase of peroxiredoxins and is involved in redox regulation

Eighteen histone deacetylases (HDACs) are present in humans, categorized into two groups: zinc-dependent enzymes (HDAC1-11) and NAD(+)-dependent enzymes (sirtuins 1-7). Among zinc-dependent HDACs, HDAC6 is unique. It has a cytoplasmic localization,...

Developing and applying a gene functional association network for anti-angiogenic kinase inhibitor activity assessment in an angiogenesis co-culture model

BACKGROUND: Tumor angiogenesis is a highly regulated process involving intercellular communication as well as the interactions of multiple downstream signal transduction pathways. Disrupting one or even a few angiogenesis pathways is often...

The PCH Family Member Proline-Serine-Threonine Phosphatase-interacting Protein 1 Targets to the Leukocyte Uropod and Regulates Directed Cell Migration

PCH family members have emerged as important regulators of membrane-cytoskeletal interactions. Here we show that PSTPIP1, a PCH family member expressed in hematopoietic cells, regulates the motility of neutrophil-like cells and is a novel component...

Vitamin D3 induces autophagy of human myeloid leukemia cells

Vitamin D3 causes potent suppression of various cancer cells; however, significant supraphysiological concentrations of this compound are required for antineoplastic effects. Current combinatorial therapies with vitamin D3 are restricted to...

High-level transfection of primary rabbit T lymphocytes

Efficient gene delivery is essential for the assessment of transgene function in untransformed hematopoietic cells. Here, we explored the utility of different non-viral and viral gene delivery techniques for primary T cells from New Zealand White...

Novel MEK1 mutation identified by mutational analysis of epidermal growth factor receptor signaling pathway genes in lung adenocarcinoma

Genetic lesions affecting a number of kinases and other elements within the epidermal growth factor receptor (EGFR) signaling pathway have been implicated in the pathogenesis of human non-small-cell lung cancer (NSCLC). We performed mutational...
