Specificity of Serine enzymes to Cancer glyco-proteins R.Cathey, 1997, RCRS In cancer chemotherapy, selective destruction is the ideal. But no artificial formulations of cytotoxins or anti-metabolites fits this description. All are general poisons, and the normal as well as the cancer cells are affected. In some cases the somatic components are alone affected in the tumor, giving the false impression that some good effect has been rendered, when in fact the ratio of the malignant component has merely increased due to ablation of the somatic elements. Tumor-size reduction is not a good measurement of tumorostatics or tumor destruction. The only reliable and consistent measurement of cancer activity is the sensitized hCG test; and ultimately patient life-extension. Even site-specific delivery of cytotoxins or antimetabolites, or radiation are not, in their effects, limited to the cancer. There is always a generalized somatic response when these compounds leach away from the lesion, or by the inherent limitations in site-specific methods developed thus far. Again all such toxic agents are inhibitors of important enzyme systems of the host. Fortunately there are endogenous counterparts to our pathetically limited ability to create artificially such a selective program: the selectively, antithetical-to-cancer serine enzymes along with the cytotoxins of the lymphocytes; and exogenous, dietarily derived nitrilosides. The rationales for the complete resolution of the cancer problem have been known and relatively well understood in the greater part for almost 100 years (John Beard, 1902, Lancet). A dietetic or exogenous component forming a part of this triply-redundant protection against the asexual generation of the life-cycle was discovered and applied rationally more recently: since the 1950s, namely Laetrile or nitrilosides. Cancer is trophoblast. Period. We challenge anyone to refute the trophoblastic nature of cancer using the same criteria of corrosive scientific critical thought and investigational methods that provided the evidences and proofs of this contention. These scientific proofs were for the most part supplied by researchers without the least knowledge of a trophoblastic or Beardian basis of cancer. Thus it is independently supported. These facts have been broadcast repeatedly over the past 95 years with little effect on the standard or generalized methods of practice. The trophoblastic fact of cancer was only most recently re-broadcast world wide in none other than the official organ of the American Cancer Society in 1995: Cancer, Volume 76, Number 8, pages 1467-75, by Dr. Hernan Acevedo, M.D. But even here, the realizations of the significance of these findings has been missed, and have spurred little more than interest in possible immunological adaptations of the cancer hormone. Cancer cells form a specifically appropriate substrate in their substance for the serine pancreatic enzymes; normal cells for the most-part do not. Where-ever normal tissues might be affected by these enzymes there are appropriate levels of enzyme inhibitors which are highly localized and the inhibition reversible. The trophoblast of pregnancy, too, form a likewise appropriate substrate for these serine enzymes, and which enzymes play the role of transforming cytotrophoblast (the malignant, erosional, metastasizing trophoblast cell) into the steroid-producing, non-dividing (relatively "benign") syncytial-trophoblast, and finally these too are completely destroyed or digested by these enzymes: principally carboxypeptidase, trypsin, chymotrypsin and amylase. Upon the complete ablation of these "pregnancy trophoblast" cells, which Hertig called nature's first cancer and nature's first cure, birth commences. Cancer being trophoblast, these same enzymes must perform the same functions here as well, as a matter of invariant natural law. It is not theory, these are commonplace facts to the experimental biologist and these established facts can all be freely examined by anyone with the willingness to examine the literature as well as the clinical record where these facts are put to practice. After the action of these pancrearic enzymes have sufficiently breached the pericellular sialomucinous coatings of the cancer/trophoblast cells the phagocytes and cytotoxic bodies of the immune system may move in and further kill and remove these completely along with the further digestion by the serine enzymes which work conjunctively and form part of the immune system. The sialomucin coating renders cancer cells immunologically inert or repulsive to the immune bodies such as the lymphocytes because they share the same electrochemical charge (negative). Just so, the conceptus is a successful "graft" by the same means. In addition, the diet provides a nutritionally essential co-factor: hydrogen cyanide from the dietary nitrilosides. Because the steroid producing phase of trophoblast elicits from the hostal tissues enzymes which degrade and serve to conjugate these cancer steroids into inert forms (namely by beta-glucuronidase:BG) therefore the dietary nitrilosides (which are glucosides that can be oxidized and conjugated to glucuronic acid to form glucuronides) are also activated or "unlocked" by BG in the environment of the cancer or trophoblast. Thus HCN is released which is a well known accelerator of proteolysis, thus aiding the pancreatic enzymes. But HCN also has the capacity to poison the cancer cell, which is specifically deficient in mechanisms or enzymes capable of detoxifying the cyanide radical. Normal tissues do possess this required means of detoxification: rhodanese, or thiosulfate transulferase, also found in foods. The synthetic nitriloside, Laetrile, is composed of a moiety of HCN and Benzaldehyde. Acting together they are more than 100 times more cytotoxic to the cancer cell than each is alone. Benzaldehyde is oxidized in the somatic environment, while the cancer cell is less capable of this, so Benzaldehyde lags in the cancer environs and kills it. In dietary nitrilosides we find one of the most potent means not only of selectively destroying the cancer cell, and preventing cancer, but of reactivation of inhibited proteolytic enzymes. That cancer cells as well as normal trophoblast secrete trypsin- and plant-derived proteolytic-enzyme-inhibitors (serpins) is a commonplace in the universe of the relevant expert in cancer research. The biochemist or enzymologist also knows that HCN is a reactivator of these important enzymes, along with glutathione and other reactivators. Furthermore, this essential factor..nitriloside..provides a means for the normalization of hypertension through its metabolite thiocyanate; which also plays a role in prevention of the crisis of sickle cell anemia; the nitrile contributes to the formation of vitamin B-12 from pro-vitamin B-12, another cyanide bearing vitamin: cyanocobalamin; Through these metabolites the nitrilosides play an important role in hemopoiesis. They are antiparasitic, bacteriostatic; through the metabolization of the nitriloside amygdalin (L-mandelonitrile-beta-diglucoside), found in apricot seeds, benzaldehyde is released, which upon oxidation yields benzoic acid, a known antirheumatic, and antiseptic. The potentiated serine enzymes due to the assistance of nitrilosides (and biologically active tri-valent chromium is important here as well) are effective against malaria, tuberculosis (against which anti-biotics are losing ground rapidly) "sticky blood" (polycythemia vera), inflammations, and a host of other chronic, metabolic disorders attributed to old-age, or as para-neoplastic syndromes. This factor meets all the criteria for a vitamin itself. In animals and man, when deprived of this factor, cancer is a commonplace; in less severe expressions of deficiency, there are still widespread susceptibility to infectious disease, pancreatic insufficiency, high blood pressure, etc. It well deserves the status of a vitamin that Dr. Krebs gave it: vitamin B-17, and the common therapeutic form Laetrile (laevo-mandelonitrile-beta-glucuronoside) is nothing more than a synthetic form of the common nitriloside amygdalin.
