Abstract
We have used neuroblastoma cells expressing NDM29 at its basal level (Mock cells) or at 5.4-fold higher levels (S1 cells) to investigate whether a functional differentiation correlates with morphological and biochemical development induced by NDM29 expression. First, analyzing the expression of spec...

Abstract
We analyzed the effects of IFN-α2b and TGF-β1 treatments on Wnt/β-catenin pathway, Smads proteins levels, β-catenin/TCF4/Smads interaction and proliferation and apoptotic death in HepG2/C3A and Huh7 cell lines. IFN-α2b and TGF-β1 attenuated Wnt/β-catenin signal by decreasing β-catenin and Fr...

Abstract
We have discovered that other cellular stressors are integrated with glucocorticoid signaling through a new hormone-independent phosphorylation site, Ser134, on the human glucocorticoid receptor (GR). Ser134 phosphorylation is induced by a variety of stress-activating stimuli in a p38 mitogen-activa...

Abstract
We addressed whether p130-DREAM is disrupted in HPV16-transformed cervical cancer cells and whether this is a critical function for E6/E7. We found that p130-DREAM was greatly diminished in HPV16-transformed cervical carcinoma cells (CaSki and SiHa) compared with control cell lines; however, when E6...

Abstract
We show that inhibition of Bcr-Abl oncogene by imatinib induces down-regulation of Jab1 in Bcr-Abl-positive K562, Ku812, and MEG01 leukemia cells suggesting Bcr-Abl may regulate Jab1 expression. Promoter deletion and mutation analysis indicate the Tcf-4/β-catenin and STAT1 binding sites located bet...

Abstract
We show that SFN treatment causes a concentration-dependent reduction in PcG protein (Bmi-1, Ezh2) expression in SCC-13 skin cancer cells and also reduces trimethylation of lysine 27 of histone H3. This is associated with accumulation of cells in G(2)/M phase; reduced levels of cyclin B1, cyclin A,...

We investigate the possible linkage between ROS, β-catenin and arsenic induced transformation and tumorigenesis in human colorectal adenocarcinoma cell line, DLD1 cells. Our results show that arsenic was able to activate p47(phox) and p67(phox), two key proteins for activation of NADPH oxidase. Ars...

We demonstrate that neutrophils accumulate in the lung prior to the arrival of metastatic cells in mouse models of breast cancer. Tumor-entrained neutrophils (TENs) inhibit metastatic seeding in the lungs by generating H(2)O(2) and tumor secreted CCL2 is a critical mediator of optimal antimetastatic...
