Hingtgen's group is already testing how
far their
tumor - homing cells can migrate using larger animal
models.
«This approach will hopefully lead to better mechanistic predictive
modeling of response and future design of therapies that
further take advantage of how the immune system recognizes
tumors.»
The mouse
model could also contribute to the
further development of immunotherapies — a method in which the body's immune system is stimulated, so that it intensifies its fight against
tumor cells.
A study combining
tumor cells from patients with breast cancer with a laboratory
model of blood vessel lining provides the most compelling evidence so
far that a specific trio of cells is required for the spread of breast cancer.
Researchers used IL - 15 to develop a whole
tumor cell vaccine to target breast (TS / A) and prostate (TRAMP - C2) cancer cells in animal
models; results showed that
tumor cells stopped growing after the vaccine was introduced and that beneficial effects were enhanced
further when IL - 15Rα was co-produced by the vaccine cells.
Shah next plans to rationally combine the toxin - secreting stem cells with a number of different therapeutic stem cells developed by his team to
further enhance their positive results in mouse
models of glioblastoma, the most common brain
tumor in human adults.
They
further investigated this phenotype in a skin
tumor model system, provided by Maria Sibilia from the Institute for Cancer Research of the Medical University of Vienna, and found that deactivating HDAC1 actually accelerates
tumor development, while HDAC2 deactivation has no effect.
When the researchers removed FAK from blood vessels that grew in melanoma or lung cancer
models, both chemotherapy and radiation therapies were
far more effective in killing the
tumors.
The researchers now have plans to conduct
further work to explore the safety and effectiveness of the approach in vivo and in advanced lung
tumor mouse
models.
These GEMM - ESCs, with often multiple modified alleles, form the basis for
further genetic engineering either by Flp - recombinase mediated integration, gene targeting or Crispr / Cas9 to allow for the evaluation of altered target gene expression in a spontaneous
tumor model.
These results indicate the importance of assessing miR function in the complex physiology of in vivo
model systems and indicate that
further functional testing of miR - 342 is required before concluding it is a bona fide
tumor - suppressor - miR.
