1.Progress in relationship between Stat3 and invasion and metastasis in cancer
Journal of International Oncology 2009;36(7):486-488
Signal transdcuers and activators of transcription3 (Stat3) is activated by a wide range of cytokines and growth factors following binding to special DNA domain and affects the expression of a variety of genes in modulating the process of cell proliferation, differentiation, and apoptosis. As a point of convergence for many oncogenic tyrosine kinase signaling pathways,it can be activited by sevral accesses. Stat3 is not only in-volved in the function of both apoptosis suppression,proliferation promotion,but also participates the process of angiogenesis,invasion and immune evasion. For repression of this way maybe a new target for break of cancer in-vasion and metastasis,blockers of Stat3 has become the focus of many researches.

Anaplastic lymphoma kinase-positive (ALK+) diffuse large B-cell lymphoma (DLBCL) is a rare subtype of DLBCL. ALK+DLBCL has a characteristic immunoblastic/plasmablastic morphology, a distinct immunophenotypic profile, and recurrent cytoge-netic/molecular genetic abnormalities. The occurrence of this type of lymphoma has been reported in both adult and pediatric popula-tions. Although rare, this new entity should be recognized because most cases follow an aggressive clinical course with a poor progno-sis. The response of ALK+DLBCL to conventional chemotherapy is poor. The recently discovered small molecule ALK inhibitor may provide a potential therapeutic option for patients with this disease.
