Inositol Hexaphosphate and Paclitaxel: Symbiotic Treatment of Oral
Cavity Squamous Cell Carcinoma.
Janus SC, Weurtz B, Ondrey FG.
>From the Department of Otolaryngology, University of Minnesota,
Minneapolis, Minnesota, U.S.A.
OBJECTIVES/HYPOTHESIS:: Nuclear factor (NF)-kappaB is an early
response gene that has been associated with head and neck squamous
cell cancer (HNSCC) progression. NF-kappaB activation is induced by
some chemotherapy agents, including paclitaxel. The activation of
this
gene can be correlated with apoptosis resistance. Inositol
hexaphosphate (IP6) is a naturally occurring polyphosphorylated
carbohydrate. NF-kappaB levels were evaluated in oral cavity HNSCC
lines after treatment with paclitaxel and IP6, alone and in
combination. Resulting levels of cell death and apoptosis were
assessed, and conclusions are drawn regarding a possible synergistic
relationship between paclitaxel and IP6. METHODS:: NF-kappaB
activation in cancer cells treated with paclitaxel and IP6, alone and
in combination, was measured by transient transfection, and results
were interpreted by luminometry. Cell proliferation of treated cells
was measured by MTT assay. Cell viability and apoptosis of cancer
cells treated with paclitaxel and IP6 combinations were quantitated
by
trypan blue staining and Caspase-Glo 3/7 assay, respectively.
RESULTS:: IP6 was observed to significantly downregulate NF-kappaB
activation in both NA and CA-9-22 oral cavity HNSCC cell lines.
Paclitaxel treatments caused increased NF-kappaB activation in the
same cell lines. IP6 was observed to mitigate paclitaxel-induced NF-
kappaB activation in the CA-9-22 cell line. IP6, when combined with
paclitaxel, reduces CA-9-22 cell proliferation, increases cell death,
and increases apoptosis, when compared with treatment with paclitaxel
alone. CONCLUSIONS:: IP6 reduces paclitaxel induced NF-kappaB
activation and increases paclitaxel-mediated cell killing and
apoptosis. As a well-tolerated and safe supplement, IP6 deserves
further study in the treatment of oral cavity squamous cell
carcinoma.

Résumé / Abstract
A glasshouse pot experiment investigated the uptake by arbuscular
mycorrhizal (AM) fungi associated with red clover of three organic
sources of P added to a sterilized calcareous soil of low P
availability. Each pot was separated into a central compartment for
plant growth and two outer compartments for external mycelium using 30-
μm nylon mesh to restrict the roots but allow hyphal penetration.
Plants in the central compartments were inoculated with the AM fungus
Glomus versiforme and uninoculated controls were included. Plants were
harvested on three occasions: 5, 7 and 10 weeks after sowing.
Application of each of the three organic P sources (lecithin, RNA and
sodium phytate) or inorganic P (KH[2]PO[4]) at 50 mg P kg[-1] to the
outer compartments of mycorrhizal and uninoculated pots increased the
yield, P concentration and total P uptake of red clover compared with
pots to which no P was applied, with no differences among P sources in
non-mycorrhizal plants but differences observed in mycorrhizal plants
both 7 and 10 weeks after sowing suggesting differences in
availability of the four P sources to AM mycelium. The contribution of
external mycelium to plant uptake of applied P increased with time.
The three organic P sources made smaller contributions to plant P
nutrition than KH[2]PO[4] at the first and second harvests. At the
third harvest, the contribution from KH[2]PO[4] was 23%, while those
from lecithin, RNA and sodium phytate were 23, 17 and 31%,
respectively. This suggests that with the mediation of AM fungi, soil
organic P sources can make a contribution to host plant P nutrition
comparable to that of soluble orthophosphate.

Résumé / Abstract
A glasshouse pot experiment investigated the uptake by arbuscular

Application of each of the three organic P sources (lecithin, RNA and
