Inhibition of Immune System by an Immunosuppressive Factor from a Human Prostatic Carcinoma Cell Line (JCA-1)

Prostatic carcinoma is the most commonly diagnosed tumor among men over 40 which results in over 30,000 deaths each year in the United States. Previous studies indicated that tumor cell lines produce and release several growth regulatory factors into their condition media and so far a number of human tumor cell-derived suppressor factors have been isolated that affect normal immune functions. I...

Purification and physicochemical characterization of a human cytotoxic factor produced by a human haemic cell line.

A cytotoxic factor, produced by a human lymphoblastoid cell line [Karpas (1977) Br. J. Cancer 35, 152--160; Karpas (1977) Br. J. Cancer 36, 437--445], was purified both from the cell extracts and from the culture medium containing the cell lysate, by using ammonium sulphate precipitation, DEAE-cellulose chromatography, gel filtration and affinity chromatography on concanavalin A--Sepharose and ...

ATM induces radioresistance of non-small cell lung cancer A549 cells by downregulation of MDMX

Background: Tumor radioresistance leads to a reduction in the efficiency of radiation therapy. It is very important to explore the cellular mechanisms leading to radioresistance and to find potential therapeutic targets, which might improve the efficacy of radiation therapy. This study was to investigate the role of ataxia-telangiectasia mutated (ATM) and murine double minute X (MDMX) in radior...

Establishment and characterization of a human non-small cell lung cancer cell line.

Lung cancer is one of the most common causes of cancer death worldwide. Although many efforts have been made to explore the mechanisms involved in the development of lung cancer, the genetic events involved in the pathogenesis of lung cancer are still unclear. For a better mechanistic scope of study, a well-established cellular model is essential. We report the establishment of a squamous cell ...

Purification and characterization of a novel monocyte chemotactic and activating factor produced by a human myelomonocytic cell line

A novel basic heparin-binding monocyte chemotactic factor (MCF) was purified to homogeneity from the conditioned media of human myelomonocytic cell line THP-1 based on its in vitro monocyte chemotactic activity. The purified MCF was homogenous and estimated to be 15 kD on SDS-PAGE. Purified MCF stimulated normal human monocytes to be growth inhibitory in vitro at 2-3 d for several human tumor c...
