The contribution of chronic antigen stimulation to the occurrence of lymphoproliferative disorder (LPD) with the gamma-delta T-cell lineage is unclear, despite the fact that Epstein-Barr virus (EBV) positive T-cell LPD is derived from antigen-stimulated cytotoxic T-cells. Given the possible associat...

Heat shock protein 90 (Hsp90) is essential for the stability and the function of many client proteins, such as ERB2, C-RAF, CDK4, HIF-1 aplha and AKT. Recent reports demonstrated that inhibition of Hsp90 modulates multiple functions required for survival of human cancer, such as myeloma (Mitsiades e...

Adult T-cell leukemia (ATL) is a fatal neoplasia derived from HTLV-1 infected T lymphocytes exhibiting constitutive activation of NF-kB. To elucidate the complex molecular mechanism of anti-tumor effect of the proteasome inhibitor, bortezomib in ATL cells, we attempted to perform gene expression pr...

MicroRNAs are a family of 19- to 25-nucleotides noncoding small RNAs that primarily function as gene regulators. Aberrant microRNA expression has been described for several human malignancies, and this new class of small regulatory RNAs has both oncogenic and tumor suppressor functions. Despite th...

Recently, the existence of extracellular miRNAs enclosed in exosomes has raised the possibility that they play an important role in cell-cell communication. To gain more insight into cell-cell communication via exosomal miRNAs, we investigated whether or not tumor cells exposed to hypoxia secrete ex...
