mice implanted with human
ovarian cancer
cells that were resistant to paclitaxel.
The researchers then used a combination of existing United States Food and Drug Administration - approved drugs to target autophagy and found
ovarian cancer
cells to be highly sensitive to these drugs in several different
mouse cancer models — even among

This was observed in human
ovarian cancer
cells grown in culture, and then in
mouse models of the disease.
They systematically deleted genes for secreted effector proteins — molecules that the parasite injects into a host
cell to modulate the immune system during infection — and injected the altered parasites into
mice with aggressive
ovarian cancer.
Their results demonstrate that specific rhoptry and dense granule effector proteins that T. gondii secretes before and after host
cell invasion, respectively, control the development of an effective host antitumor response, and increase the survival of
mice with
ovarian tumors.
But the discovery of vast numbers of immature eggs dying in the ovaries of
mice led Tilly's team to find what they claim are hidden

cells that can sprout new eggs to replace
After receiving a transplant of
ovarian cancer
cells,

While previous research had shown some effectiveness of this molecule in a
mouse model of
ovarian cancer, that benefit was limited by the immunosuppressive environment within tumors, particularly the presence of regulatory T
cells (Tregs).
They then tested the circuit in
mice implanted with
ovarian cancer
cells, and demonstrated that it could trigger T
cells to seek out and kill the cancer
cells without harming other
cells around them.
In another set of experiments, the team implanted human
ovarian carcinoma
cells into
mice.
Recent studies have demonstrated that
mouse ES
cells can differentiate into female and male germ
cells in vitro, thus producing

cells 2, 3.
To prepare
ovarian cells,
ovarian tissues were isolated from 1 - day - old F2 female
mice produced by interbreeding C57BL6 × CBA F1
mice.

mice injected with
ovarian cancer
cells.
