High Dose Vitamin C- Cancer
Treatment- Direct Benefits & As Adjunct to Other Treatments
B Windham (Ed), DAMS Intl,
2021
More than half of colorectal cancers (CRCs)
harbor activating mutations in KRAS or BRAF, yet those cancers are the most
refractory to current targeted therapies. Our group and others showed that
oncogenic mutations in KRAS or BRAF contribute to the Warburg effect and the
addiction to glucose in part by upregulating a glucose transporter, GLUT1, that
allows cancer cells to take up glucose efficiently. These data suggest a
strategy for targeting KRAS or BRAF mutant cancer by exploiting the selective
expression of GLUT1 and the metabolic liability that comes with increased
reliance on glycolysis. Indeed, by targeting these unique features in these
cancer cells, we recently showed that high dose vitamin C could selectively kill
KRAS or BRAF
mutant CRC cells.
While
KRAS and BRAF mutations are certainly two of the most frequently mutated
oncogenes in human cancer, they are not the only mutations known to affect
glucose metabolism and sensitivity towards ascorbate therapy.
Now a
growing number of preclinical studies are showing how high-dose vitamin C might
benefit cancer patients. In our view, the implementation of this treatment
paradigm could provide benefit to many cancer patients.

Blaszczak
et al,
Experimental
studies have shown the ability of pharmacological doses of vitamin C alone or
in combinations with clinically used drugs to exert beneficial effects in
various models of human cancers. Cytotoxicity of high doses of vitamin C in
cancer cells appears to be related to excessive reactive oxygen species
generation and the resulting suppression of the energy production via
glycolysis. A hallmark of cancer cells is a strongly upregulated aerobic
glycolysis, which elevates its relative importance as a source of ATP
(Adenosine 5'-triphosphate). Aerobic glycolysis is maintained by a highly
increased uptake of glucose, which is made possible by the upregulated
expression of its transporters, such as GLUT-1, GLUT-3, and GLUT-4. These
proteins can also transport the oxidized form of vitamin C,
dehydroascorbate
,
permitting its preferential uptake by cancer cells with the subsequent
depletion of critical cellular reducers as a result of ascorbate formation.
Ascorbate also has a potential to affect other aspects of cancer cell
metabolism due to its ability to promote reduction of
iron(
III)
to iron(II) in numerous cellular metalloenzymes. Among iron-dependent
dioxygenases, important targets for stimulation by vitamin C in cancer include
prolyl hydroxylases targeting the hypoxia-inducible factors HIF-1/HIF-2 and
histone and DNA demethylases. Altered metabolism of cancer cells by vitamin C
can be beneficial by itself and can also promote activity of specific drugs.

The data from the study indicate that oral delivery of 4 g of vitamin C encapsulated in liposomes produces circulating concentrations of vitamin C that are greater than non-encapsulated oral, but less than achieved by intravenous administration. The levels of ascorbate that were achieved in plasma after 4 grams vitamin C were 1419 uM for intravenous ascorbate, 124 uM for un-encapsulated and 170 uM for encapsulated (liposomal) ascorbate.

There is high-quality
clinical evidence on the safety and effectiveness of IVC. The existing evidence
is suggestive of a good safety profile and potentially important antitumor
activity; IVC has improved the quality of life and symptom severity of some
patients with cancer, and several cases of cancer remission have been reported.

The new study shows that tumor cells with low levels
of catalase enzyme activity are much less capable of removing hydrogen peroxide
than normal cells, and are more susceptible to damage and death when
they are exposed to high doses of vitamin C

The epigenetic role of vitamin C in health and disease , Cell Mol Life Sci 2016 Apr;73(8):1645-58,
Recent advances have uncovered a previously unknown function
of vitamin C in epigenetic regulation. Vitamin C exists predominantly as an
ascorbate anion under physiological pH conditions. Ascorbate was discovered as
a cofactor for methylcytosine dioxygenases that are responsible for DNA
demethylation, and also as a likely cofactor for some JmjC domain-containing
histone demethylases that catalyze histone demethylation. Variation in
ascorbate bioavailability thus can influence the demethylation of both DNA and
histone, further leading to different phenotypic presentations. Ascorbate
deficiency can be presented systematically, spatially and temporally in
different tissues at the different stages of development and aging. Here, we
review how ascorbate deficiency could potentially be involved in embryonic and
postnatal development, and plays a role in various diseases such as
neurodegeneration and cancer through epigenetic dysregulation.

Entacapone (ENT), a clinical drug for the treatment of Parkinson's disease, has been shown to have antioxidant effects. ENT is an antioxidant that can scavenge toxic HOCl and ONOO- species and inhibit oxidative stress-induced cell death more effectively than vitamin C and vitamin E. ENT may have new clinical applications as an antioxidant in the treatment of ROS-induced diseases including cardiovascular disease, cancer, and neurodegenerative diseases.
Vitamin C May Help Fight
Cancers
There is strong scientific evidence
that high doses of vitamin C are a tool against some cancers. According to
DiNicolantonio's
video, liposomal vitamin C can produce
blood levels that have a 50% kill rate against lymphoma cells in vitro — a
dramatic finding.
28
Vitamin C has shown effectiveness
against prostate, pancreatic, hepatocellular, colon, mesothelioma and
neuroblastoma cell lines.

According
to the Stephenson Cancer Center:
30
"The
potential mechanisms through which treatment with high-dose ascorbic acid may
exert its effects on cancer cells have been extensively investigated. Several
studies have demonstrated that the in vitro direct cytotoxic effect of ascorbic
acid on various types of cancer cells is mediated through a chemical reaction
that generates hydrogen peroxide.
Treating
colon cancer cells with 2 mM to 3 mM of ascorbic acid resulted in downregulation
of specificity protein (
Sp
) transcription factors,
iron metabolism disruption, and
Sp
-regulated genes
involved in cancer progression.
One study
suggested that ascorbate-mediated prostate cancer cell death may occur through
activation of an autophagy pathway … Another in vitro study found that ascorbic
acid killed colorectal cancer cells with KRAS or BRAF mutations by inhibiting
the enzyme glyceraldehyde 3-phosphate dehydrogenase."

Medicinal mushrooms and fungi
are thought to possess approximately 130 medicinal functions, including
antitumor, immunomodulating, antioxidant, radical scavenging, cardiovascular,
anti-hypercholesterolemic, antiviral, antibacterial, anti-parasitic,
antifungal, detoxification, hepatoprotective, and antidiabetic effects. Many,
if not all, higher Basidiomycetes mushrooms contain biologically active
compounds in fruit bodies, cultured mycelium, and cultured broth. Special
attention is paid to mushroom polysaccharides. The data on mushroom
polysaccharides and different secondary metabolites are summarized for
approximately 700 species of higher hetero- and homobasidiomycetes. Numerous
bioactive polysaccharides or polysaccharide-protein complexes from the
medicinal mushrooms described appear to enhance innate and cell-mediated immune
responses, and exhibit antitumor activities in animals and humans. Whilst the
mechanism of their antitumor actions is still not completely understood,
stimulation and modulation of key host immune responses by these mushroom
compounds appear central. Polysaccharides and low-molecular-weight secondary
metabolites are particularly important due to their antitumor and
immunostimulating properties. Several of the mushroom compounds have been
subjected to Phase I, II, and III clinical trials, and are used extensively and
successfully in Asia to treat various cancers and other diseases.
