OBJECTIVE To explore the molecular mechanism by which Biejiajian pills inhibit hepatocellular carcinoma in a nude mouse model bearing HepG2 cell xenograft. METHODS The inhibitory effect of Biejiajian pills on the growth of HepG2 cell xenograft in nude mice was observed. Immunohistochemical method was used to examine proliferating cell nuclear antigen (PCNA) expression in HepG2 cell xenograft,...
Traditional approaches to the preclinical investigation of cancer therapies rely on the use of established cell lines maintained in serum-based growth media. This is particularly true of small-cell lung cancer (SCLC), where surgically resected tissue is rarely available. Recent attention has focused on the need for better models that preserve the integrity of cancer stem cell populations, as we...
Previous studies have shown that pretransplant donor lymphocyte infusion (DLI) can enhance xenograft survival. However, the mechanism by which DLI induces xenograft survival remains obscure. Using T cell subset-deficient mice as recipients we show that CD4+, but not CD8+, T cells are necessary to mediate the rejection of concordant cardiac xenografts. Adoptive transfer of naive CD4+ T cells ind...
Genomic studies in human acute lymphoblastic leukemia (ALL) have revealed clonal heterogeneity at diagnosis and clonal evolution at relapse. In this study, we used genome-wide profiling to compare human T cell ALL samples at the time of diagnosis and after engraftment (xenograft) into immunodeficient recipient mice. Compared with paired diagnosis samples, the xenograft leukemia often contained ...
