Open AccessPreclinical validation of Aurora kinases-targeting drugs in osteosarcoma
Aurora kinases are key regulators of cell cycle and represent new promising therapeutic targets in several human tumours.

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 ...

Open AccessAdvances in preclinical therapeutics development using small animal imaging and molecular analyses: the gastrointestinal stromal tumors model
The large use of target therapies in the treatment of gastrointestinal stromal tumors (GISTs) highlighted the urgency to integrate new molecular imaging technologies, to develop new criteria for tumor response...

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...

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...

Article
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...

Article
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...

Article
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...

Article
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...

Article
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...

Article
In vitro differentiation of rhabdomyosarcomas induced by nickel or by Moloney murine sarcoma virus
In vitro cultures and clonal derivatives have been established from rat rhabdomyosarcomas induced by Moloney-Murine Sarcoma Virus (MSV) or by nickel sulfide; differentiation ability has been studied as express...

Enhancement of experimental metastatic ability by tumor necrosis factor-alpha alone or in combination with interferon-gamma
The effects of recombinant tumor necrosis factor-alpha (TNF-alpha) and interferon-gamma (IFN-gamma) on B16 mouse melanoma experimental metastatic ability and major histocompatibility complex (H-2b) antigens expre...
