The purpose of this study was to determine whether the methods for isolating tumor cells from a human renal cell carcinoma (HRCC) influence the biological behavior of the cancer cells. Renal cell carcinoma obtained from a surgical specimen was dissociated by enzymatic treatment and cells were plated into culture dishes or injected s.c. into the kidney of BALB/c nude mice. The resultant kidney t...

Staphylococcus aureus is the leading cause of skin infections. In a mouse model of S. aureus skin infection, we found that lesion size did not correlate with bacterial burden. Athymic nude mice had smaller skin lesions that contained lower levels of myeloperoxidase, IL-17A, and CXCL1, compared with wild type mice, although there was no difference in bacterial burden. T cell deficiency did not e...

Abstract Calmodulin-binding transcription activator 1 (CAMTA1) is a factor located on chromosome 1p, and we have recently reported that CAMTA1 expression reduced neurosphere formation tumor growth in nude mice, suggesting can function as suppressor experimental glioma. In the present study, investigated molecular network of CAMTA-1 glioma cells. We established cell lines with doxycycline-induci...

An in vivo assay of ablastin activity was developed by passive transfer of ablastic serum into nude mice. Preparations of Trypanosoma musculi that contained 35 to 50% dividing forms removed ablastic activity from mouse serum, but absorption of serum with a parasite preparation consisting of less than 5% dividing forms did not appreciably alter ablastic activity. These data suggest that ablastin...

The microvasculature in the ear of a nude mouse is captured using transmission optical microscopy.

The aim of the present study was to establish an animal liver metastasis model with human colon cancer and investigate the inhibitory effect of the wild type (WT) p53 gene combined with thymidine kinase/ganciclovir (TK/GCV) and cytosine deaminase/5-fluorocytosine (CD/5-FC) systems on liver metastasis of colon cancer. A nude mouse liver metastasis model with human colon cancer was established vi...

Crucial steps in tumor growth and metastasis are proliferation, survival, and neovascularization. Previously, we have shown that receptors for CXCL-8, CXCR1, and CXCR2 are expressed on endothelial cells and CXCR2 has been shown to be a putative receptor for angiogenic chemokines. In this report, we examined whether tumor angiogenesis and growth of CXCL-8-expressing human melanoma cells are regu...

The thymic lesion of the nude mouse causes a profound block in T cell development. The failure of most T cells to mature in nude mice is likely to reflect a requirement for signals elaborated in the normal thymus. Interleukin 7 (IL-7), a lymphokine that is normally expressed in the thymus and has been implicated in T cell maturation, might be central to this process. To test this possibility, w...
