Modified Citrus Pectin & Galectin-3 The Role of Modified Citrus Pectin and Galectin-3 in the Prevention and Treatment of Metastatic Cancer
Elevated Galectin-3 in the body is directly involved in: – Cancer – Cardiovascular Disease – Chronic Hepatitis – Kidney Disease – Diabetes – Inflammation & Fibrosis – Others Galectin-3 & Disease
Overall Average 11.9 Galectin-3 Levels & Mortality from All Causes in the General Population: PREVEND
In Cancer, Galectin-3 plays a role in: – Cell to Cell Adhesion – Aggregation of Cancer Cells – Tumor Growth – Metastasis – Angiogenesis – Inhibition of Apoptosis Galectin-3 & Cancer
MCP is derived from the pith of citrus fruit peels Complex polysaccharide fiber of repeating galacturonic acid groups with neutral sugar side chains Unmodified citrus pectin molecular weight 50 to 300 kiloDaltons (kDa) with esterification ~70% Optimal biological activity: molecular weight <13 kDa with esterification <10%, and specific structure What is Modified Citrus Pectin (MCP) ?
Binds to Galectin-3 molecules Blocks aggregation of cancer cells Blocks docking of cancer cells Blocks interactions with endothelium necessary for angiogenesis Modified Citrus Pectin is a Galectin-3 Blocker

Human Clinical Study (Number of Participants ) Type of TrialResults Zhoa, et al., Altern Ther Health Med (n = 7) Pilot trial: Lead toxicity in hospitalized children ages Very significant decrease in blood serum levels of lead (P =.0016) and very significant increase in 24-hour urine collection (P =.0007). No adverse effects. Azémar, et al., Clinical Medicine: Oncology (n = 49) Pilot trial: To assess the quality of life, clinical benefit and antitumoral efficacy in advanced stage solid tumors (colorectal, prostate, breast, kidney, cervix/uterine, liver, pharynx, pancreatic, melanoma, stomach, bile duct carcinoma and chondrosarcoma) 22.5% patients showed a stable disease (SD) and 12.3% patients had a SD for a period longer than 24 weeks. One patient with metastasized prostate carcinoma showed a 50% decrease in serum PSA level after 16 weeks of treatment associated with a significant increase of clinical benefit, quality of life and decrease in pain. 20.7% patients had an overall clinical benefit response associated with a stabilization or improvement of life quality. All patients tolerated the therapy well without any severe adverse events. Eliaz, et al. Forsch Komplementmed (n = 5) Case studies: Involving lowering of lead and mercury body burden 5 case studies presented show reduction in toxic heavy metals was achieved without side effects. Gradual decrease of total body burden is believed to have played an important role in recovery and health maintenance. Seven Clinical Studies with MCP
Human Clinical Study (Number of Participants) Type of TrialResults Eliaz, et al. Phytother Res (n = 8) Pilot trial: Toxic heavy metal removal in healthy population In the first 24 hours the urinary excretion of arsenic increased significantly (p < 0.05). On day 6, urinary excretion was increased significantly for cadmium (p < 0.05). Lead showed a dramatic increase in excretion (p < 0.08), and mercury approached significance on day six. Other elements analyzed including essential elements did not show any significant change in excretion. Eliaz. 228th Annual American Chemistry Meeting. August (n = 5) Pilot trial: Decrease total body burden of mercury A significant decrease in total body mercury burden was seen in all participants. The decrease was found more significant over time. The mercury burden for the group dropped 68.32% (p=0.0313). All individual completed the study, and there were no side effects reported. Guess, et al. Prostate Cancer Prostatic Dis (n = 13) Phase II pilot trial: Lengthening of PSA doubling time in biochemical relapsed prostate cancer patients. There were no serious side effects in any patient, but three patients withdrew from the study due to abdominal cramping or diarrhea. MCP was well tolerated by the remaining 10 evaluable patients. Seven (70%) of these evaluable patients had a significantly increased doubling time of PSA compared with their times before the treatment. Strum, et al.

DeFillipi et al, U.S. Cardiology, 7,1, 3–6 (2010) clearly indicate that circulating Galectin-3 is an important factor in fibrosis of many organs and organ systems, and that reducing circulating Galectin-3 may have an important role in remediating cardiac injury and progression to heart failure (HF). Similarly, Psarras et al, Eur. Heart J., April 26 (2011) demonstrate that reduction in Galectin-3 levels in the myocardium may reduce fibrosis in the heart and improve outlook. De Boer et al, Ann. Med., 43,1, 60–68 (2011) identify Galectin-3 as a key indicator in cardiac health. Shash et al, Eur J. Heart Fail., 12,8, 826–32 (2011) identify Galectin-3 levels as a key agent in heart failure through fibrosis. De Boer et al. Eur. J. Heart Fail., 11, 9, (2009) link an increase in Galectin-3 expression and presence to heightened fibrosis, and heart failure. The same article links Galectin-3 to inflammation. Inflammation is the hallmark of arteriosclerosis, therefore Galectin-3 levels also contribute to coronary artery disease, peripheral artery disease, strokes, and vascular dementia.

Background: Folic acid (FA)-induced acute kidney injury model Method: Mice given 1% MCP-supplemented water, or plain water, 1 week before FA injection Results: During initial injury phase, all FA treated mice lost weight while their kidneys enlarged secondary to renal insult – Gross changes significantly lessened in MCP group – MCP clearly reduced renal cell proliferation – Recovery phase: MCP group showed decreased Galectin-3 expression with decreased renal fibrosis, macrophages, pro- inflammatory cytokine expression, and apoptosis MCP & Kidney Injury Study
Galectin-3 Mediates Aldosterone- Induced Vascular Fibrosis Calvier L, Miana M, Reboul P, et al. Arterioscler Thromb Vasc Biol Jan;33(1):67-75.
Background: Aldosterone is involved in arterial stiffness and heart failure. Galectin-3 plays an important role in inflammation, fibrosis, and heart failure. MCP blocks Galectin-3 Methods and Results: Rats were treated with aldosterone combined with MCP for 3 weeks. Hypertensive aldosterone- treated rats presented vascular hypertrophy, inflammation, fibrosis, and increased aortic Gal-3 expression. Those also treated with MCP treatment abolished all the above effects. Conclusion: Galectin-3 is required for inflammatory and fibrotic responses to aldosterone in vascular smooth muscle cells in vitro and in vivo. By inhibiting Galectin-3, MCP prevents vascular fibrosis. Aldosterone Galectin-3 MCP Vascular Fibrosis Study
