Small interfering RNA-based molecular therapy of cancers / 癌症

RNA interference (RNAi) has become a gold standard for validating gene function in basic life science research and provides a promising therapeutic modality for cancer and other diseases. This mini-review focuses on the potential of small interfering RNAs (siRNAs) in anticancer treatment, including the establishment and screening of cancer-associated siRNA libraries and their applications in anticancer drug target discovery and cancer therapy. This article also describes the current delivery approaches of siRNAs using lipids, polymers, and, in particular, gold nanoparticles to induce significant gene silencing and tumor growth regression.

Differential expression of genes in dendritic cell induced by human alloantigens and cytomegalovirus antigen / 白血病·淋巴瘤

[Objective]To investigate differential gene expression in dendritic cell(DC) in response to human alloantigen and cytomegalovirus protein,and search target genes which can prevent graft rejection and eytomegalovirus (CMV) infection.[Methods]Genome-wide microarray analysis was performed to test gene expression in DC in response to human alloantigen and cytomegalovirus protein 3A(CMV3A).[Results]The Results showed that the difference of gene expression of DC induced by CMV3A and alloantigen was significant.The genes with differential expression included antigen processing and presentation,toll-like receptor signaling pathway and cell movement/migration, cytokine-cytokine receptor interaction and metabolism of xenobiotics by cytochrome p450,and several heat shock protein(HSP) family members including HSPA5,HSPA8,HSPA9B and HSP90AB1,in DC induced hy alloantigen were higher expression than that by CMV3A.[Conclusion]This study found several genes including heat shock protein family in DC induced by alloantigen were higher expression than that by CMV3A,these genes might play a valuable role in preventing graft rejection and CMV infection.
