Nanoparticles carry cancer-killing drugs into tumor cells

...To answer this question, we examined ten different ovarian cancer cell lines. In doing this we found out that 40% of these specimens contained none or only a few DR4 receptor molecules." It was proven in further tests that these cells react particularly badly to TRAIL. This proves that the missing receptor a...

Still, the most provocative finding was that "Oct4 causes tumors by preventing adult stem cells in these tissues from differentiating," says Hochedlinger. In other words, with Oct4 active, the stem cells could replicate themselves indefinitel...

Biomarkers isolated from saliva successfully predict oral and breast cancer

...cers and other difficult to detect cancers such as ovarian and pancreatic cancers. "In my mind the biggest hurdle stems from the fact that salivary nucleic acids or protein markers might be influenced by eating, drinking, smoking, diet or oral hygiene," said Wong.

Wahl explained that in patients with known cancer, work-ups focus on a patient's primary disease and incidental coexistence of another primary malignant lesion can be missed. "Such newly ...

First frozen egg baby born in Canada

.... Initially, she planned to undergo treatment with ovarian stimulation and intra-uterine insemination (IUI). Because she produced too many follicles in her ovaries, the treatment cycle had to be cancelled because of a high risk of multiple-fetal pregnancy. As an alternative treatment, she had eggs collected ...

Harmful chemicals may reprogram gene response to estrogen

...ne that is linked to inherited forms of breast and ovarian cancer, showed that those women born before 1940 had a much lower risk of developing breast cancer than women born after 1940. The researchers believe this discrepancy is due to differences in diet, exercise, hormonal factors and chemical exposures. ...
