Herceptin then delivers the package to the tumor cell, where it releases the toxic cargo to kill the cancer.
Tumor cell evolution limits what can be known about cancer in a patient.
The evolutionary nature of cancer implies, contrary to conventional wisdom, that the essential features of any therapy for the consistent cure or control of cancer must be independent of the particular pathways of tumor cell evolution, and independent of any particular genetic or epigenetic alterations.
Oncologists will be able to take a single tumor cell from a cancer patient and determine within minutes or hours which aberrant genes are responsible for the cancer's growth, allowing them to customize therapy to the patient's particular genetic quirks, rather than having to guess which drugs might work best.
But most of the bleeding occurred in patients who had a particular type of tumor, called a squamous cell tumor.
Additional studies will evaluate the effectiveness of the pill in glioblastoma, a lethal brain tumor, small-cell lung cancer and prostate cancer.
Concern about possible dire health effects from using cell phones stems in large part from the publicizing of certain results from human and laboratory studies as well as from stories about individuals who developed a brain tumor after years of cell phone use.
Dr Lorenz Studer, head of the Stem Cell and Tumor Biology Laboratory at the centre, and the lead researcher on the study, told BBC News Online that the study was "proof of principle" that cloned embryonic stem cells could be reliably transformed into a variety of useful cell types.
On the FDA's Fast Track and in phase III testing is the company's BAY 43-9006, a small molecule RAF kinase and VEGF inhibitor that inhibits tumor growth for patients with metastatic renal cell carcinoma (advanced kidney cancer).
Millennium's test detects melastatin, a skin gene that may slow cell division, and thus inhibit tumor growth.
Cannabinoids may cause antitumor effects by various mechanisms, including induction of cell death, inhibition of cell growth, and inhibition of tumor angiogenesis and metastasis.

According to an AP report, the chemical keeps the drug combination intact until it binds to a cancer cell and delivers its anti-tumor cocktail.

In particular, those with squamous cell cancer, a particular type of tumor, were excluded.
The chemical keeps the cocktail intact until it binds to a cancer cell, delivering a potent dose of anti-tumor poison.
But some tumor cells have proteins that bind to the PD-1 receptors, shutting the immune cell down.
The scientists found that a cell-signaling protein, or cytokine, known as a hippocampal TNF (tumor necrosis factor) played a limited role.
Using tumor samples from wo-men with breast cancer, he used a gadget called a cell sorter to sift through dozens of different proteins on the surface of breast cancer cells, searching for patterns that might identify stem cells.
It showed participants in the study who used a cell phone for 10 years or more had doubled the rate of brain glioma, a type of tumor.
Hardell has been a vocal promoter of his results as indicating that long-term cell phone use appears to be associated with increased risk of glioma, the most fatal type of brain tumor.
