Staining for fluorescent bands and centromeric heterochromatin showed that normal mouse chromosomes could be identified as specific arms in most of the biarmed chromosomes of the mouse cell line LMTK–. Seven marker chromosomes were also characterized. The karyotype was heterogeneous with an average of 9.4 biarmed chromosomes per cell. Five specific biarmed chromosomes were present in at least 90% of the cells examined. The results indicate the presence of both relatively stable and highly variable components in the in vitro karyotype. Evidence is presented which indicates that the biarmed chromosomes have been formed by reciprocal translocation, centric fusion with retention of both centromeres, and centromeric misdivision with isochromosome formation.

Immunotherapy is a promising new approach for cancer treatment. In this study, I propose to use the THαβ-mediated immune response for cancer treatment. The THαβ-mediated immune response is activated by IL-10 and IL-15. Thus, I used IL-10 and-15 as therapeutic agents in the 4T1 cell line, which is a mouse cell line of breast cancer, and the NXS2 cell line, which is a mouse cell line of neuroblastoma. Cells from 4T1 and NXS2 were subcutaneously inoculated in wild type BALB/c female mice and AJ mice, respectively, and administered cytokines or an antibody treatment at various dosages. My results showed that IL-10 and IL-15 administration led to reduction in tumor volume and increase in survival. However, traditional TH1 cytokine IFN-γ administration led to increase in tumor volume and decline in survival. Antibody treatment in conjunction with IL-10 was not significantly better than IL-10, due to the expression of GD2 on immune cells. Moreover, an anti-GD2 antibody inhibited the immune cells themselves. Additionally, I found that IL-10 was directly toxic to tumor cells in vitro. Thus, I conclude that the THαβ immunological pathway is a good treatment strategy for cancer.
