Mutated tumor suppressor gene p53 leads to better results Presence of normal p53, a tumor suppressor gene, instead of a mutated version, makes breast cancer chemotherapy with doxorubicin less effective. The preclinical study led by MD Anderson scientists was published today in the journal Cancer Cell. The research, which challenges the existing paradigm, is another step closer to personalized cancer medicine for breast cancer. "It's really important to understand the genetic defects...

ADAM28, a metalloproteinase belonging to the ADAM gene family, cleaves the von Willebrand factor (VWF) and inhibits VWF-mediated cancer cell apoptosis, thereby enhancing lung metastases, so inhibiting its expression gives a substantial reduction in lung metastases, according to a study published June 8 in the Journal of The National Cancer Institute. Several ADAMs are known to be found in tumors and are linked with both tumor growth and cancer progression in humans. While ADAM28 is...

Scientists build a synthetic peptide that overcomes cancer cells´ survival defenses Scientists at the Dana-Farber/Children's Hospital Cancer Center have developed an anti-cancer peptide that overcomes the stubborn resistance to chemotherapy and radiation often encountered in certain blood cancers when the disease recurs following initial treatment. The strategy could pave the way for much needed new therapies to treat relapsed and refractory blood cancers, which are difficult to...

The BCL-2 protein family plays a large role in determining whether cancer cells survive in response to therapy or undergo a form of cell death known as apoptosis. Cells are pressured toward apoptosis by expression of pro-apoptotic BCL-2 proteins. However, cancer cells respond to therapy by increasing expression of anti-apoptotic proteins, which bind and neutralize pro-apoptotic family members and mediate therapeutic resistance. Therefore, development of therapeutic strategies to neutralize...

Scientists optimistic that targeting pathway's cellular transcription process will lead to death of multiple myeloma cells Researchers at NYU School of Medicine have identified a target for slowing the progression of multiple myeloma by using currently available drugs. Published recently in Nature Cell Biology, the study reveals a pathway that, if deactivated, may help slow the development of the disease. "We have the ability to target this pathway with drugs that already exist,"...

A new study describes a compound that selectively kills cancer cells by restoring the structure and function of one of the most commonly mutated proteins in human cancer, the "tumor suppressor" p53. The research, published by Cell Press in the May 15th issue of the journal Cancer Cell, uses a novel, computer based strategy to identify potential anti-cancer drugs, including one that targets the third most common p53 mutation in human cancer, p53-R175H. The number of new cancer patients...

Stem Cells Poised To Self-Destruct For The Good Of The Embryo
2012-05-03 10:58:28

Embryonic stem cells – those revered cells that give rise to every cell type in the body – just got another badge of honor. If they suffer damage that makes them a threat to the developing embryo, they swiftly fall on their swords for the greater good, according to a study published online May 3, 2012 in the journal Molecular Cell. The finding offers a new glimpse into the private lives of stem cells that could help scientists use them to grow new neurons or other cells to...


Word of the Day
omadhaun
  • A fool; a simpleton: a term of abuse common in Ireland and to a less extent in the Gaelic-speaking parts of Scotland.
This word is partly Irish in origin.
