ABSTRACT
Vasculogenic mimicry(VM) refers to the plasticity of malignant tumor cells forming vessel networks to provide blood supply to perfusion of rapidly growing tumors. Key proteins associated with classical, stem cell, hypoxia-related and other multiple signaling pathways, which are involved in regulating functional plasticity of tumor cell VM, have become potential clinical therapeutic targets and diagnostic indicators of the aggressive, metastatic phenotype. VM has been observed in several tumor types and its occurrence is strongly associated with a poor prognosis. This review focuses on the origin and signal molecules and cascades involved in VM, and the clinical significance of VM regarding anti-angiogenesis treatment modalities.

ABSTRACT
The human La protein is recently identified as a host factor potentially involved in the post-transcriptional regulation of hepatitis B virus (HBV) RNA. The La binding site is mapped to a predicted stem-loop structure within a region shared by all HBV RNAs, and it is known that human La protein protected HBV RNA against Rnase-mediated degradation. HLa mutants lost the ability of binding and protecting HBV RNA, which make it easy for HBV RNA to degrade and the virus replication to terminate. This review summarizes the latest investigation about the interaction of La protein,HBV RNA and Nuclear RNases, and discusses the possible mechanisms of HBV RNA degradation, the effect of La protein and its mutants on the translation initiation of HBV RNA, and the replication of the virus.
