Introduction:
The high incidence of lung cancer and ineffective toxic action of current mono and doublet chemotherapy approaches result in poor patient survival. Enzymes called matrix metalloproteinases (MMPs), which degrade the extracellular matrix are implicated in neoplastic invasion and metastasis. A nutrient mixture (NM) containing lysine, proline, arginine, ascorbic acid, and green tea extract has shown significant antitumor effects, including inhibition of MMPs and invasion. Based on this, we investigated the effect of NM on human lung carcinoma cell A-549 cells in vitro and in vivo.

Introduction:
Malignant mesothelioma (MM), an asbestos-associated cancer with no known cure, is a highly aggressive tumor causing profound morbidity and nearly universal mortality. Extracellular matrix (ECM) matrix metalloproteinases (MMPs) produced by tumor and stromal cells play a key role in tumor invasion and metastasis. Prevention of ECM degradation by MMP inhibition has been shown to be a promising therapeutic approach to inhibition of cancer development. A nutrient mixture (NM) containing lysine, proline, ascorbic acid and green tea extract, has shown significant anticancer activity against a number of cancer cell lines.

Abstract:
Matrix metalloproteinases (MMPs) secreted by lung cancer (LC) and malignant mesothelioma (MM), especially MMP-2 and MMP-9, play crucial roles in tumor invasion and metastasis. We examined the effect of cytokines, mitogens, and inhibitors on MMP-2 and MMP-9 expression in LC and MM cell lines. Human LC (A-549) and MM (MSTO-211H) cell lines were cultured in appropriate media.

Abstract:
Lung cancer, a leading cause of cancer death, is associated with exposure to inhalation carcinogens, most commonly those found in tobacco smoke. We investigated the in vivo effect of dietary supplementation with a nutrient mixture containing lysine, proline, ascorbic acid and green tea extract (NM) on the development of urethane-induced lung tumors in male A/J mice.
