Open AccessHuman responses against HER-2-positive cancer cells in human immune system-engrafted mice
Human immune system (HIS)-engrafted mice are new tools to investigate human immune responses. Here, we used HIS mice to study human immune responses against human HER-2-positive cancer cells and their ability ...

Therapy of lung metastases through combined vaccination with carcinoma cells engineered to release IL-13 and IFN-γ
TS/A spontaneous mouse mammary adenocarcinoma cells were engineered to release interferon-γ (IFN-γ), a Th1 cytokine (TS/A-IFNγ) and interleukin-13 (IL-13), a Th2 cytokine (TS/A-IL13). Mice bearing lung micrometas...

Prevention of spontaneous neu-expressing mammary tumor development in mice transgenic for rat proto-neu by DNA vaccination
The HER-2/neu proto-oncogene is overexpressed in 20–30% of human breast cancers and is associated with high recurrence risk. The oncogenic potential of HER-2/neu, together with its elevated expression in tumor...

Wild-type p53-mediated down-modulation of interleukin 15 and interleukin 15 receptors in human rhabdomyosarcoma cells
We recently reported that rhabdomyosarcoma cell lines express and secrete interleukin 15 (IL-15), a tightly regulated cytokine with IL-2-like activity. To test whether the p53-impaired function that is frequen...

Therapy of murine mammary carcinoma metastasis with interferon γ and MHC gene-transduced tumour cells
Gene-transfected tumour cells were used to cure mice bearing lung metastases by the parental, non-transduced mammary adenocarcinoma (TSA-pc). Repeated subcutaneous (s.c.) administrations of mitomycin C (MitC)-...

Redundancy of autocrine loops in human rhabdomyosarcoma cells: induction of differentiation by suramin
Three human rhabdomyosarcoma cell lines were used to investigate the presence of autocrine loops based on the production of insulin-like growth factor (IGF)-II, basic fibroblast growth factor (bFGF) and epider...

Decreased adhesion to endothelial cells and matrix proteins of H-2Kb gene transfected tumour cells
Transfection of murine metastatic B78H1 cells (derived from B16 melanoma) with a syngeneic H-2Kb gene was used to study the effect of Major Histocompatibility Complex (MHC) gene products on tumour cell adhesio...

Uncoupling of growth inhibition and differentiation in dexamethasone-treated human rhabdomyosarcoma cells
The effects of dexamethasone, a synthetic glucocorticoid, and of N,N-dimethylformamide on in vitro growth and differentiation and on proto-oncogene expression of human rhabdomyosarcoma cells were studied. RD/1...

Control of H-2 expression in transformed nonhaemopoietic cells by autocrine interferon
The relationship between autocrine interferon (IFN) production and the expression of class I Major Histocompatibility Complex (MHC) membrane glycoproteins in vitro was investigated in a panel of murine transfo...

Induction of myogenic differentiation in human rhabdomyosarcoma cells by ionising radiation, N,N-dimethylformamide and their combination
Differentiation-inducing ability of gamma-radiation, N,N-dimethylformamide and their combination has been tested on human rhabdomyosarcoma RMZ-RC2 clone cells. Ionising radiation at 2-5 Gy doses induced a more...

RMZ: A new cell line from a human alveolar rhabdomyosarcoma. In vitro expression of embryonic myosin
The RMZ cell line was established from a bone marrow metastasis of a human alveolar rhabdomyosarcoma. Since the beginning of the in vitro culture, RMZ cells showed differentiation-related morphological heterogene...

Colony-stimulating activity from the new metastatic TS/A cell line and its high- and low-metastatic clonal derivatives
We investigated the presence of colony-stimulating factor (CSF) in supernatants obtained from TS/A, a new metastatic murine cell line, and from its high-and low-metastatic clonal derivatives (E and F clones, r...
