Cellular Medicine
in Cancer
Cellular Medicine provides a new perspective
in the developmental steps of cancer and its metastasis and new
safe, effective therapeutic options.
Choices and Outcomes in
Cancer Treatment:
For decades, standard treatment for cancer has consisted of surgery,
radiation and chemotherapy. Radiation and chemotherapy, the most
frequently used therapies, not only are ineffective in providing
a cure, but also indiscriminately attack all cells – healthy
and cancerous, causing cellular damage and destruction of the
body’s connective tissue, the defense against cancer metastasis.
Both radiation and chemotherapy trigger the development of new
cancers and damage the immune system and body organs. In addition,
these interventions activate enzymes that facilitate the release
of cancer cells from a localized area to spread to other organs.
At Matthias Rath Research, we have achieved a
breakthrough in cancer research by defining the cellular mechanisms
involved in cancer proliferation and metastasis and developed
a natural means of controlling these mechanisms. Efficient control
of the spread of a disease by collagen-dissolving enzyme blocks
has been successful with several diseases. This is especially
important in diseases for which orthodox medicine has no preventive
or healing therapies yet. A combination of natural nutrients formulated
to support the body in curbing metastasis and reversing tumor
growth, has been shown to be effective against a variety of human
cancer cell lines, without adverse effects on normal cells. Please
select a title below to read the respective research study.
|
How
Cancer Spreads (Metastasis):
All forms of cancer spread with the
help of a collagen dissolving mechanism. To reproduce and
spread to other parts in the body, cancer cells degrade
the extracellular matrix (ECM) by secreting various matrix
metalloproteinases (MMPs), which have been correlated with
the aggressiveness of tumor growth. With the help of these
collagen-dissolving enzymes, cancer cells can bull doze
their way though the extracellular matrix (ECM) and capsule
enclosing the tumor and through an adjacent blood vessel
wall, to be carried to other sites where the cancer cells
can invade other organs, as shown below. |
|
Cancer Metastasis – Normal cells become cancerous
cells, which secrete matrix metalloproteinases (MMPS). MMPs
destroy the extracellular matrix (ECM), enabling cancer
cells to escape and spread to distal organs through the
bloodstream.

Bladder
cancer, a cancer that develops mainly in older adults, is
the fourth most frequently diagnosed cancer in men. Once the
cells have metastasized, prognosis is poor. We investigated
the antitumor effect of a unique nutrient formulation containing
lysine, proline, arginine, ascorbic acid, and epigallocatechin
gallate on human bladder cancer cells T-24 in cell culture,
by measuring critical parameters in cancer development and
spread, such as MMP expression and cancer cell invasive potential.
Our results showed significant inhibition of invasion and
of MMP-2 and –9 expression, which suggest that this
nutrient combination is potentially an excellent candidate
for prevention and treatment of bladder cancer. |

Standard
treatment of synovial sarcoma, a soft tissue with a high (50%)
metastatic rate has met with poor results. In this study,
we investigated the inhibitory effect of a unique nutrient
mixture (NS) containing lysine, proline, arginine, ascorbic
acid, and epigallocatechin gallate on metastatic potential
of human synovial sarcoma cells SW 982, by measuring MMP expression
and Matrigel invasion in cell culture. We found NS to inhibit
the expression of both MMP-2 and -9 in a dose-dependent fashion
with virtual total inhibition of MMP-2 at 500 µg/ml
and MMP-9 at 50 µg/ml concentration of NS. The invasion
of human synovial sarcoma cells through Matrigel was significantly
reduced at 500 µg/ml (79%) and totally inhibited at
1000 µg/ml concentration of the synergistically acting
nutrient mixture (p<0.0001). These results are important
as they demonstrate that NS is an excellent candidate for
treatment of synovial sarcoma by inhibiting critical steps
in metastasis. |

Incidence
and mortality from breast cancer in women, the third most
prevalent cancer worldwide, is steadily increasing, especially
in developed societies. This study examined the synergistic
effect of a specific formulation of nutrients containing lysine,
proline, ascorbic acid and green tea extract on the growth
of mammary tumors induced in 50-day-old female Sprague-Dawley
rats by the carcinogen N-methyl-N-nitrosourea (MNU). Nutrient
Synergy significantly inhibited the incidence, as well as
the growth, of MNU-induced mammary tumors, indicating that
it has strong potential as a useful therapeutic regimen for
inhibiting breast cancer development. |

Recent
clinical studies have shown that hormone replacement therapy
(HRT) in menopausal women increases the risk of tumor development
in estrogen-sensitive tissues. In this study, estradiol stimulated
breast cancer (MCF-7) cell growth, MMP expression, matrix
invasion, and VEGF secretion (measure of angiogenesis) were
observed in culture. These pro-carcinogenic effects of estradiol
were significantly inhibited by Nutrient Synergy, suggesting
this is an excellent candidate for preventative and therapeutic
use in the treatment of estrogen-related breast cancer. |

Breast
cancer, worldwide the most prevalent cancer and the second
leading cause of cancer deaths in women today (after lung
cancer), metastasizes by the enzymatic destruction of surrounding
connective tissue to metastasize. This study demonstrated
that the nutrient mixture of lysine, proline, ascorbic acid

MMP expression and Matrigel invasion. These results suggest
that this nutrient formulation is a valuable and promising

Cervical
cancer is the seventh most common cancer worldwide and the
second most common cancer in women. Untreated dysplasia and
carcinoma in situ leads to 30% to 40% invasion within ten
years. We studied the synergistic effect of a unique nutrient
formulation containing lysine, proline, arginine, ascorbic
acid, and epigallocatechin gallate on metastatic parameters
on human cervical cancer cells such as effect on MMP-2 and
–9 expression and cancer cell invasive potential. Our
results demonstrated complete inhibition of Hela MMP-2 expression
at 1000 µg/ml and MMP-9 at 500 µg/ml, and of Matrigel
invasion at 500 µg/ml. NM demonstrated complete inhibition
of cervical DoTc2 4510 cell expression of MMP-9 at 500 µg/ml
and of invasion at 1000 µg/ml. These findings are significant
as they suggest that the nutrient mixture would be an effective
and safe therapeutic regimen for treatment of cervical cancer.

This study shows that specific
nutrients combined in a synergy have a potential to curb neuroblastoma tumor growth
in vivo by about 30%. In addition, by inhibiting secretion of MMPs, the enzymes essential
for degradation of collagen and connective tissue surrounding all cancer cells, they
can curb cancer spread in the body. Prevention of ECM degradation by inhibition of
MMP activity has been shown to be a promising therapeutic target in cancer. Our unique
nutrient mixture (NM) containing lysine, proline, ascorbic acid and green tea extract
inhibited the secretion of both MMP-2 and MMP-9 with their total blockage at NM concentration
of 100 mg/ml. These results are significant as they demonstrate therapeutic potential
in treatment of neuroblastoma by safe and effective micronutrient synergy. |

Tumor
metastasis is a major reason for treatment failure in cancer
patients. Metastatic malignant melanoma is an extremely aggressive
cancer with no current viable therapy. The primary objective
of our study was to investigate whether a unique non-toxic
nutrient mixture (NM) that has shown potent anti-tumor effects
in a number of cancer cell lines, could inhibit experimentally
induced lung metastasis of melanoma cells in C57BL/6 mice.
Intravenous injection of melanoma cells into C57BL/6 mice
has been shown to result in pulmonary metastasis, providing
an excellent model to assess test agents on metastasis. This
study demonstrated the effectiveness of NM in halting metastasis
of B16FO cells in mice, especially when delivered by iv or
ip. Furthermore, pre-incubation of tumor cells with NM for
18 hrs prior to injection into the mice completely prevented
the development of lung tumors in these mice. These results
are significant since they clearly demonstrate the anti-metastatic
potential of NM, a non-toxic nutrient mixture. |

Cellular
production of matrix metalloproteinases contributes to tumor
progression, invasion and metastasis. We investigated whether
cellular invasion and production of MMPs by a leukemia cell
line, Jurkat T, can be affected by a unique nutrient mixture
(NM) consisting primarily of lysine, proline, ascorbic acid
and green tea extract. We have demonstrated previously (Harakeh
et al. 2006) that this nutrient mixture was effective in inducing
apoptosis in this and other leukemia cell lines. In addition,
it has been shown to exhibit anti-tumor activity both in vitro
and in vivo against a number of cancer cell lines. NM exhibited
antiproliferative effect on human acute Jurkat T cells at
500?g/ml, and dose-dependent inhibition of MMP-9 secretion
and Matrigel invasion, with total blockage of MMP-9 secretion
at 500 ?g/ml NM and of invasion at 1000 ?g/ml NM. These results
are significant as they confirm previous data and indicate
that NM is potentially a promising therapeutic agent for acute

Degradation
of extracellular matrix (ECM) is a hallmark of tumor invasion, metastasis
and angiogenesis. Based on a multitargeted approach to cancer by using
natural substances to control ECM stability and enhancing its strength we
developed a novel formulation (NM) of lysine, proline, ascorbic acid and
green tea extract that has shown significant anti-cancer activity against
a number of cancer cell lines. Using various in vitro and in vivo
experimental models, we found that NM significantly inhibited angiogenesis
and metastasis of various cancer cell lines. These results suggest that
the nutrient mixture (NM) has strong therapeutic potential treating various
cancers by blocking angiogenesis and tumor invasion and metastasis. |

Consumption
of high amounts of tea has been associated with lower incidence
of stomach cancer. Furthermore, In vitro and in vivo studies
have demonstrated the anti-cancer activity of green tea, black
tea and their active constituents. However, plasma levels
of EGCG after human consumption of green tea products indicate
poor absorption of EGCG. We sought to determine if EGCG absorption
could be enhanced with red onion (quercetin) supplementation.
The results demonstrated that increasing the amount of quercetin
given along with EGCG could increase absorption of EGCG from
the intestine. Thus, the anticancer activity of the nutrient
mixture (EF) can be enhanced with quercetin intake by increasing
plasma levels of EGCG. |

Head and neck squamous cell carcinomas (HNSCC),
the sixth most common malignancies in the United States, are known for their aggressive growth and propensity
to invade and metastasize. We investigated the effect of a novel nutrient mixture (NM) containing ascorbic
acid, lysine, proline, and green tea extract, shown to have potent antitumor effects on many cancer cell
lines, on the growth of human HNSCC xenografts in athymic nude mice, as well as investigating this cell line
in vitro, evaluating viability, MMP secretion, invasion and morphology. NM inhibited the growth of tumors by
50% and exhibited dose-response toxicity to cells in vitro, with 50% toxicity at 1000 µg/ml. In addition, NM
inhibited the invasive parameters of MMP secretion and Matrigel invasion by cells in a dose-dependent manner
with total block of MMPs at 1000 µg/ml and invasion at 500 µg/ml. These results are significant as they suggest
that NM, a relatively safe therapeutic agent, has great potential in treatment of HNSCC in suppressing tumor
growth and metastasis. |

In conclusion, this
study has shown that exposure of the highly metastatic renal cell carcinoma cell
line 786-0 to different growth factors increases secretion of MMP-9 but not MMP-2;
MMP-2 and-9 activity was decreased by exposure to inhibitors. Further studies are
in progress to confirm the role of MMP-9 on Matrigel invasion using PMA, cytokines
and LPS. |

Renal
adenocarcinoma, the 17th most frequent cancer worldwide, is
associated with good prognosis if treated when still localized
to the kidney; however, once metastasized, prognosis is poor.
We investigated the effect of a unique nutrient formulation
(NM) of lysine, proline, arginine, ascorbic acid, and epigallocatechin
gallate on its effect in vitro on modulation of metastatic
parameters in human renal adenocarcinoma cell line 786-0.
NM significantly inhibited MMP expression and Matrigel invasion
in a dose-dependent fashion, with total inhibition of MMP-2
at 500 µg/ml, MMP-9 at 100 µg/ml and invasion
at 1000 µg/ml. These results indicate NM has great potential
in therapeutic use for treatment of renal carcinoma. |

Renal
cell carcinoma invasion is associated with its ability to
degrade the extracellular matrix by local production of gelatinase
enzymes (MMP-2 and MMP-9). Although many studies on renal
carcinoma have demonstrated the importance of MMPs, very little
information is currently known regarding the effect of inhibitors
and inducers of MMPs. We studied the effect of inducers (PMA,
TNF-alpha, IL-1 beta, and LPS) and inhibitors (EGCG, doxycycline,
actinomycin D, cyclohexamide, retinoic acid, dexamethasone
and H-7) on RCC 786-0 MMP expression. Our results indicate
that MMP-2 expression was not influenced by inducers such
as PMA, cytokines (IL-1b, TNFa), and LPS; the induction of
MMP-9 was associated with the specific inducer used: highest
with PMA, intermediate with cytokines, and none with LPS.
The inhibitors tested affected both MMP-2 and MMP-9 expression.
Further studies are in progress to confirm the role of MMP-9
on Matrigel invasion using PMA, cytokines and LPS. |

The
effects of a novel nutrient formulation Nutrient Synergy (NS)
were evaluated on proliferation and induction of apoptosis
using non-cytotoxic concentrations against HTLV-1 positive
(HuT-102 & C91-PL) and negative (CEM & Jurkat) cells.
NS showed anti-proliferative effect as determined by MTT assay
and TGF mRNA protein expression using RT-PCR. NS resulted
in the down-regulation of TGF-alpha and an up-regulation in
TGF-beta2. NS caused a significant increase in apoptotic cells
in the preG(1) phase. These results were confirmed using Cell
Death ELISA and Annexin V-FITC. Induction of apoptosis was
caused by an up-regulation of p53, p21 and Bax protein levels
and a down-regulation of Bcl-2alpha protein expression level. |

Leukemia,
a disorder of bone marrow characterized by unrestrained white
blood cell proliferation, results in formation of metastatic
colonies and penetration through matrix barriers and blood
vessel walls. Degradation and invasion through matrix barriers
and vessel walls is mediated by secretion of MMPs. A nutrient
mixture (NM) containing lysine, proline, ascorbic acid and
green tea extract exhibited significant inhibition of Matrigel
invasion (with total block at 1000 µg/ml) and significant
antiproliferative effect at 500 µg/ml (70%) and 1000
µg/ml (90%). These results are important as they indicate
NM is a promising therapeutic agent for leukemia. |

Acute
myeloid leukemia (AML), the most common leukemia in adults,
is characterized by uncontrolled proliferation of myeloid
blasts or lymphoid cell lines. Although chemotherapy and supportive
management have resulted in high remission rates, fewer than
50% of young patients and 10%-15% of patients over 60 years
are cured of their disease. We found that the nutrient mixture
(NM) of ascorbic acid, lysine, proline, and green tea extract
demonstrated a potent synergistic anticancer effect by inhibiting
human promyelocytic leukemia cell HL-60 proliferation, MMP
activity, and invasion through Matrigel in vitro. Our results
are significant as they indicate that this nutrient mixture
is a promising non-toxic therapeutic agent for acute myeloid
leukemia. |

Adult
T-cell leukemia (ATL) is an aggressive malignancy caused by
HTLV-1, for which currently there is no proven therapy. Nutrients,
such as ascorbic acid, lysine, and EGCG used individually
and in combination with other nutrients (e.g., proline and
N-Acetyl-L-Cysteine), were effective in inhibiting the growth
of virus-infected and virus-negative leukemia cell types.
These nutrients were used in concentrations that did not affect
the viability of normal cells, but were effective in killing
leukemia cells. Our study results confirm our previous findings
that a specific combination of nutrients can be a powerful
tool in suppressing cancer cell growth and viability, including
blood cancers such as ATL. |

Liposarcoma,
a fat cell malignancy, commonly metastasizes (usually to lungs
and liver). Overall 5-year survival rate of patients with
deep high-grade liposarcoma is less than 50%. Extracellular
matrix (ECM) matrix metalloproteinases (MMPs) produced by
tumor and stromal cells play a key role in tumor invasion
and metastasis. The nutrient mixture (NM) of lysine, proline,
ascorbic acid and green tea extract significantly inhibited
liposarcoma cell growth, MMP expression and invasion - important
parameters for cancer prevention. These results are significant
as they indicate that the nutrient mixture has therapeutic
potential as a non-toxic treatment strategy for liposarcoma. |

this study, ascorbigen, a major indole-containing compound
in cabbage, was found to be toxic to human melanoma, liver,
and colon cancer cell lines. In addition, it was found to
inhibit cellular MMP expression, a measure of metastatic potential. |

Ascorbic
acid and its derivatives have been shown to be cytotoxic and
inhibit the growth of a number of malignant and non-malignant
cell lines in culture and in animal models. In this study,
ascorbic acid, which is water-soluble, was not toxic to the
melanoma and liver cancer lines tested; however, the lipophilic
(lipid soluble) derivatives studied were found to be markedly
toxic to these cell lines. This implies that these lipid-soluble
derivatives, which can cross cell membranes and the blood
brain barrier, have therapeutic potential in the treatment
of cancer. |

The
results of this study show that this nutrient mixture administered
in a diet was effective in a significant inhibition of metastasis
of B16FO melanoma cells to the lungs. By exposure to higher
concentrations of NM, such as obtained through iv or ip delivery,
an enhanced inhibitory effect was obtained (up to 86%). It
is important to note that the exposure of tumor cells to
NM before their injection to the mice completely prevented
development of lung tumors (100% inhibition of metastasis). |
