We have found the solution to the back reaction of putting a stack of coincident D3 and D5 branes in R 3,1 × M6, where M6 is constructed from an infinite class of Sasaki-Einstein spaces, L (p,q,r). The non-zero fluxes associated to 2 and 3-form suggests the presence of non-contractible 2 and 3-cycles in this geometry. The radial part of the warp factor has(More)
Studies on interaction of tumor cells with extracellular matrix (ECM) components showed increased extracellular protease activity mediated by the family of matrix metalloproteinases (MMPs). Here we studied the effect of human breast cancer cell line MCF-7-laminin (LM) interaction on MMPs and the underlying signaling pathways. Culturing of MCF-7 cells on LM(More)
