Melbourne researchers have shown a type of leukemia can be successfully ‘reversed’ by coaxing the cancer cells back into normal development. The discovery was made using a model of B-progenitor acute lymphoblastic leukemia (B-ALL), the most common cancer affecting children.
A new study shows that a tumor-associated lipid stimulates specific T cells, which efficiently kill leukemia cells both in vitro and in animal models.
Scientists from the Broad Institute and Massachusetts General Hospital (MGH) have conducted a first-of-its-kind study that characterizes the cellular diversity within glioblastoma tumors from patients. The study, which looked at the expression of thousands of genes in individual cells from patient tumors, revealed that the cellular makeup of each tumor is more heterogeneous than previously suspected.
Federal funding for cancer research has diminished over the last ten years, and the negative impact on research is now apparent. There were no blockbuster revelations, no flashy new kid on the block, no miracle cures at this year’s ASCO. Of the four studies selected for the plenary session (where presentations are often THE important findings of the conference), only one is predicted to have a major impact on patient care.
By themselves, PAX3 and MAML3 don’t cause any problems. However, when they combine during an abnormal but recurring chromosomal mismatch, they can be dangerous. The result is a chimera—a gene that is half of each—and that causes biphenotypic sinonasal sarcoma. The tumor usually begins in the nose and may infiltrate the rest of the face, requiring disfiguring surgery to save the individual.
Women who often indulge their cravings for hamburgers, steaks and other red meat may have a slightly higher risk of breast cancer, a new study suggests. Doctors have long warned that a diet loaded with red meat is linked to cancers including those of the colon and pancreas, but there has been less evidence for its role in breast cancer.
Scientists at UC Santa Barbara have designed a nanoparticle that has a couple of unique — and important — properties. Spherical in shape and silver in composition, it is encased in a shell coated with a peptide that enables it to target tumor cells. What’s more, the shell is etchable so those nanoparticles that don’t hit their target can be broken down and eliminated.
Twelve years ago, researchers found that a protein called Set2 plays a role in how yeast genes are expressed– specifically how DNA gets transcribed into messenger RNA. Now, it has been discovered that Set2 is also a major player in DNA repair, a complicated and crucial process that can lead to the development of cancer cells.
New genomic research revealed that two common gene variants that lead to longer telomeres, the caps on chromosome ends thought by many scientists to confer health by protecting cells from aging, also significantly increase the risk of developing the deadly brain cancers known as gliomas.
Vitamin D has been shown to play an important role in liver function. Now, a new study in Western Europeans shows that vitamin D lowers the risk of developing hepatocellular carcinoma (HCC), the main form of liver cancer.
Metastatic cancer cells, which can migrate from primary tumors to seed new malignancies, have thus far been resistant to the current arsenal of anticancer drugs. Now, researchers have identified a critical weakness that actually exploits one of these cells’ apparent strengths—their ability to move and invade tissues.
Improved diagnosis and management of one of the most common cancers in men- prostate cancer- could result from research, which has discovered that seminal fluid (semen) contains biomarkers for the disease.
Surgery and radiation for a glioblastoma have only limited effectiveness because the tumor is particularly aggressive, infiltrating brain tissue surrounding the primary tumor. Scientists have developed a technique designed to open the blood-brain barrier at targeted locations just far enough to allow the passage of drug-bearing nanoparticles.
A test that counts the number of locations in tumor specimens where tumor cells may invade blood vessels predicted the risk of distant spread, or metastasis, for the most common type of breast cancer.
Researchers are reporting promising treatment milestones for patients with deadly skin and lung cancers who are being treated with an experimental drug called MK-3475.
New research confirms a vulnerability to lung cancer can be inherited and implicates the BRCA2 gene as harboring one of the involved genetic mutations. The study scanned the genomes of more than 11 thousand individuals of European descent to look for common variations associated with non-small cell carcinoma. The analysis showed that variations in the BRCA2 and CHEK2 genes can significantly increase an individual's risk for lung cancer.
Among men treated for prostate cancer, those who received radiation therapy were more likely to develop bladder or rectal cancer, according to a new study.
A multicenter team of researchers report that a commercial test designed to rule out the presence of genetic biomarkers of prostate cancer may be accurate enough to exclude the need for repeat prostate biopsies in many— if not most— men.
The risk of developing the most deadly form of skin cancer, melanoma, was more closely related to sun exposure in early life than in adulthood in young Caucasian women, according to a new study.
UT Southwestern Medical Center cancer researchers have identified a protein critical to the spread of deadly cancer cells and determined how it works, paving the way for potential use in diagnosis and eventually possible therapeutic drugs to halt or slow the spread of cancer.
Could a common sexually transmitted infection boost a man’s risk for prostate cancer? A new study is exploring the connection between prostate cancer and the parasite that causes trichomoniasis, the most common non-viral sexually transmitted infection in men and women.
Accumulation of DNA damage can cause aggressive forms of cancer and accelerated aging, so the body’s DNA repair mechanisms are normally key to good health. However, in some diseases the DNA repair machinery can become harmful. Now, scientists have discovered some of the key proteins involved in one type of DNA repair gone awry.
In a discovery at the Children’s Medical Center Research Institute at UT Southwestern (CRI), a research team has taken a significant step in cracking the code of an atypical metabolic pathway that allows certain cancerous tumors to thrive, providing a possible roadmap for defeating such cancers.
Working with mice, researchers report they have identified chemical signals that certain breast cancers use to recruit two types of normal cells needed for the cancers’ spread.
Scientists have shown how switching off a key protein in pancreatic cells slows the spread of the disease to other tissues, a key step which can mean patients have just weeks to live.
