Does altered expression of cell adhesion molecules lead to differential uptake of hypericin in urothelial cancer?
Our study has unraveled one of the many factors contributing to the selective uptake of hypericin in bladder cancer. We have thus identified the effects of alteration of E-cadherin-catenin complex and transformed intercellular junction in the modified paracellular uptake of hypericin that provides the rationale for using this photosensitizer in photodynamic diagnosis of bladder carcinoma.
Disruption of GC signaling in osteoblasts significantly attenuates K/BxN mouse serum-induced autoimmune arthritis in mice. These data suggest that osteoblasts modulate the immune-mediated inflammatory response via a GC-dependent pathway.
