Sentences with phrase «glioblastomas grow»

Another is that the transplanted bits of tumor act nothing like cancers in actual human brains, Fine and colleagues reported in 2006: Real - life glioblastomas grow and spread and resist treatment because they contain what are called tumor stem cells, but tumor stem cells don't grow well in the lab, so they don't get transplanted into those mouse brains.

During a conversation this month in his office at Weill Cornell Medicine in New York City, Fine rattled off more dismal stats, like the many failed clinical trials of experimental drugs for glioblastoma; like the paltry increase in life expectancy for people with glioblastoma from 12 months in 1990 to 15 today; like the stupid (in hindsight) assumptions about how glioblastomas grow and how to study them in mice.

Not exact matches

In 2009 he had been diagnosed with a type of rapidly growing brain tumor called a high - grade astrocytoma that, despite aggressive treatment, eventually evolved into a glioblastoma — the highly malignant brain tumor that also took the lives of Vice President Joe Biden's son, Beau, in 2015 and former Sen. Ted Kennedy in 2009.

Small populations of adult stem cells with somewhat limited developmental potential are responsible for the body's ability to heal injuries and replace worn out cells and tissues, and evidence is growing that rare cancer stem cells are responsible for the uncontrolled growth of some malignant tumors, including glioblastoma.

These were released into tumour cells that had been taken from glioblastoma patients and grown in the lab.

The team found that exposing samples of human glioblastoma tumours grown in a dish to the Zika virus destroyed the cancer stem cells.

Several studies have supported a role for cancer stem cells in the aggressive brain tumors called glioblastoma, but those studies involved inducing human tumors to grow in mice, and as such their relevance to cancer in humans has been questioned.

A glioblastoma tumor requires large amounts of energy as it grows, and the dietary intervention works by drastically limiting the tumor's supply of glucose, Reynolds said.

From tissue and cell samples from five glioblastoma patients, the scientists obtained 33 individual cancer cells capable of reproduction, which grew into very different tumors in the lab.

According to his unpublished findings, when he puts glioblastoma cells from patients into lab dishes with brain organoids, the cells attach to the surface of the organoids, burrow into them, and within 24 to 48 hours grow into a mass that eventually «looks exactly like what happened in the patient's own brain,» Fine said.

The team's next steps are to test coibamide A in a mouse model for triple negative breast cancer and in a mouse model for brain cancer in which the glioblastoma cells are grown in the brain instead of the flank.

Glioblastomas are particularly difficult to treat because these tumors grow exceptionally quickly and do not respond well to most available chemotherapy drugs.

Glioblastoma, is an aggressive cancer in which tumors grow rapidly and spread rapidly to new sites.

The findings may even have implications for studying glioblastoma, a common brain cancer whose ability to grow, migrate and hack into the brain's blood supply appears to rely on a pattern of gene activity similar to that now identified in these neural stem cells.

In addition, a growing number of immunotherapy clinical trials are in place to test this groundbreaking approach on other cancers like lymphoma, multiple myeloma, and for solid tumors, through trials in glioblastoma, mesothelioma, and ovarian and pancreatic cancer.
