Colorectal cancer is the second most deadly cancer in the United States and there is an urgent need to develop effective preventive and therapeutic strategies against it. The aim of our study was to investigate the antitumor effects of a nutrient mixture containing ascorbic acid, lysine, proline and green tea extract that has been previously demonstrated a strong anticancer activity in several cancer cell types. We studied the effect of NM on human colon cancer cell line HCA-7 in vitro by measuring cancer cell proliferation, invasion, and expression of pro-inflammatory COX-2 and COX-1 proteins.

Colorectal, pancreatic and hepatic carcinomas are characterized by high levels of matrix metalloproteinase (MMP)-2 and -9 secretions that degrade the ECM and basement membrane, allowing cancer cells to spread to distal organs. Proteases play a key role in tumor cell invasion and metastasis by digesting the basement membrane and ECM components. Strong clinical and experimental evidence demonstrates association of elevated levels of uPA and MMPs with cancer progression, metastasis and shortened patient survival.

The incidence of hepatocellular carcinoma (HCC), once thought to be a rare tumor in North America, has rapidly increased in recent years in the United States. Current treatment modalities to halt the progression of this disease are only marginally effective. The mainstay treatment is liver transplantation, which is often confronted with donor shortage. Invasion, metastasis and recurrence contribute to the high mortality rate of this disease. Matrix metalloproteinases (MMPs) that degrade the extracellular matrix (ECM) have been associated with the progression, invasion and metastasis of the disease.

Purpose: Long-term survival of patients with hepatocellular carcinoma (HCC), a common cancer worldwide, remains poor, due to metastasis and recurrence. We investigated the effect of a novel nutrient mixture (NM) of chemopreventive agents containing ascorbic acid, lysine, proline, and green tea extract on human HCC cell line Sk-Hep-1 in vivo and in vitro.

Antitumor Effect of a Combination of Lysine, Proline, Arginine, Ascorbic Acid, and Green Tea Extract on Pancreatic Cancer Cell Line MIA PaCa-2

Current treatment of pancreatic cancer is generally associated with poor prognosis, even if diagnosed early, due to aggressive rate of metastasis and non-responsiveness to chemotherapy and radiotherapy. Matrix metalloproteinases (MMPs) have received much attention in recent years for their role in various malignancies, and have been implicated in tumor invasion, metastasis and angiogenesis.
