Epithelial-mesenchymal transition (EMT) is a developmental program, which is associated with breast cancer progression and metastasis. Here, we report that ectopic overexpression of SOX4 in immortalized human mammary epithelial cells is sufficient for acquisition of mesenchymal traits, enhanced cell migration, and invasion, along with epithelial stem cell(More)
The large-scale, heterogeneous, and distributed nature of the Smart Grid poses many challenges to be overcome from communication networking to autonomous control and management. The underlying infrastructure of Smart Grid must be efficient and reliable in transmitting large amounts of real-time data, scalable and flexible in aggregating resources, and(More)
Epithelial-mesenchymal transition is a change of cellular plasticity critical for embryonic development and tumor metastasis. CDK5 is a proline-directed serine/threonine kinase playing important roles in cancer progression. Here we show that CDK5 is commonly overexpressed and significantly correlated with several poor prognostic parameters of breast cancer.(More)
The DNA-damaging drug doxorubicin (Dox) induces cell senescence at concentrations significantly lower than those required for induction of apoptosis. At low Dox concentrations, tumor suppressor p53 is activated, which enhances the expression of p21(Waf1/Cip1) (p21). At high concentrations, Dox activates p53 leading to apoptosis without enhancing p21(More)
The Pro23 to Thr (P23T) mutation in human gammaD-crystallin (HGD) shows several cataract phenotypes. We found earlier [A. Pande, O. Annunziata, N. Asherie, O. Ogun, G.B. Benedek, J. Pande, Decrease in protein solubility and cataract formation caused by the Pro23 to Thr mutation in human gamma D-crystallin, Biochemistry 44 (2005) 2491-2500] that the mutation(More)

BMP4 (bone morphogenetic protein 4) is a multifunctional cytokine known to exert its biological effects through a variety of signalling pathways. The diverse function of BMP4 appears to be due to multiple pathways activated by BMP4 itself. Our previous studies have demonstrated that BMP4 is able to drive lung cancer cells into a process of premature(More)
Inactivation of the tumor suppressor p53 and activation of the oncogene Ras are the two most pivotal events in tumor development. However, potential intersection between p53 and Ras activity during an EMT process, which plays a crucial role during malignant tumor progression, remains elusive. Here, we report that increased expression of wild type p53(More)
