Profiling of Cancer Genes May Lead to Earlier Detection Human Cancers

... analyzed 45 of these new genes in both normal and cancerous tissues from the same patients and found that many of the genes were methylated specifically in the tumor samples. “We ended up with a large number of genes that are involved in the development of lung cancer that, despite years of work in the fie...

...t other tumor cells. Though successive trials on cancerous tumors of mice have been carried out, use of virotherapy as the third arm of cancer treatment, along with radiation and chemotherapy is still several years of research away, says Seymour. The scientists plan to begin trials of the coated virus on h...

'Beavertail' Surgery Helps Tongue Cancer Patients

...h swallowing. The surgery involves removing the cancerous tissue and replacing it with a healthy paddle of skin and connective tissue with artery intact, and connecting it to healthy blood vessels in the neck. The beavertail of fat that comes with the skin is connected to the base of the tongue to add bulk,...

Surgery and Adjuvant Therapy Can Work for Pancreatic Cancer

...ve margins (some healthy tissue cut out around the cancerous cells), between 1975 and 2005, to remove pancreatic adenocarcinoma. They excluded patients who had metastatic cancer, tumors that could not be removed or were not removed entirely (positive surgical margins), or indolent (slow growing) tumor types. ...

Role of RNA in Checking the Development of Tumors

...R gene could help prevent the growth of neoplastic cancerous cells, ordinary cells which develop into tumour cells, such as in prostate cancer cells," explains Dr Akoulitchev. "In fact, the first anti-cancer drug, Methotrexate, acts by binding and inhibiting the enzyme produced by this gene." Dr Akoulitchev b...

New Test Predicts CLL’s Sensitivity to Experimental Drug

...year, is an easy mark for the new drug because the cancerous cells are strongly dependent on a particular survival molecule, Bcl-2, that keeps the self-destruct signals at bay. They showed that the investigational drug neutralizes the Bcl-2 action, unleashing molecules that trigger suicide in the cancer cells,...

Cancer Scientists' Gene Research Offers New Treatment Hope

...nes in causing the uncontrolled proliferation of a cancerous cell into a tumour. The radical approach is to use molecules of RNA - a substance similar to a gene's DNA - to "silence" or switch off certain key genes known to be involved in the growth of tumours. One team at the University of Oxford has shown i...

Scientists Identify Pancreatic Cancer Stem Cells

... in pancreatic cancer, the research team implanted cancerous tissue from human pancreatic specimens removed during patient surgery in “xenograft” mice with compromised immune systems. Researchers removed tumors after they grew, and then sorted millions of cancer cells to isolate those that had one or more of t...

...d the magic bullet because it directly attacks the cancerous cells without side effects like hair loss or vomiting, costs about Rs.100,000 (over $2,000) per shot. For a full treatment, six to seven doses might be required which brings the costs to Rs.600,000-700,000. Not everyone can afford this kind of treatm...

New Protein Inhibitor Halts Growth Of Cancerous Cells

... BI 2536 can indeed effectively halt the growth of cancerous cells, both in cell culture and in an animal model for human tumor growth. BI 2536 caused growth arrest and cell death in cell lines derived from a variety of human cancers, and it inhibited the growth of human tumor grafts in mice, resulting in the ...
