Showing 2151 - 2174Human Genes May Not Be Patented, Rules the Supreme Court
The U.S. Supreme Court ruled unanimously on Thursday that isolated human genes may not be patented. However, the creation of synthetic forms of DNA, known as complementary DNA (cDNA), is eligible for patent protection. The decision resolves the question brought before the Supreme Court justices in...
Newly Identified Markers May Predict Who Will Respond to Breast Cancer Prevention Therapy
Single nucleotide polymorphisms (SNPs) in or near the genes ZNF423 and CTSO were associated with breast cancer risk among women who underwent prevention therapy with tamoxifen and raloxifene, according to data published in Cancer Discovery, a journal of the American Association for Cancer Research. ...
Research Team Identifies Genetic Risk for Cancer in Breast Cells
An Indiana University cancer researcher and his Canadian collaborator have discovered how normal breast precursor cells may be genetically vulnerable to developing into cancer. David Gilley, PhD, Associate Professor of Medical and Molecular Genetics at the IU School of Medicine and a researcher at ...
Study Paves Way for Rational Drug Targeting of B-cell Lymphomas
A new study from Dana-Farber Cancer Institute may help clinicians and drug researchers choose the most promising genetic targets to attack in a common type of non-Hodgkin lymphoma. The report, published in the June 10 issue of Cancer Cellprovides a new, “big picture” view of an...
Potential New Way to Suppress Tumor Growth Discovered
Researchers at the University of California, San Diego, School of Medicine, and University of Rochester Medical Center have identified a new mechanism that appears to suppress tumor growth, opening the possibility of developing a new class of anticancer drugs. The findings were published in this...
DNA Sequencing Reveals Mucosal Melanoma's Genetic Fingerprint
Scientists have found a molecular "bullseye" for a rare form of melanoma, opening up opportunities for novel targeted treatment, according to new research published in the Journal of Pathology. Whole genome and whole exome sequencing carried out at Cancer Research UK’s Paterson Institute for ...
ASCO 2013: More than 20% of African American Women Carry Inherited Mutations in at Least One Breast Cancer Susceptibility Gene
A genomic profiling study of African American women with breast cancer found that about one in five carries an inherited abnormality in at least 1 of 18 genes associated with breast cancer susceptibility. Such mutations were more prevalent among women with aggressive triple-negative breast cancer,...
ASCO 2013: Cervical Cancer Screening Using Visual Inspection with Vinegar Reduces Mortality by 31% in Large Study in India
Cervical cancer mortality was reduced by 31% over a period of 15 years among women screened with biennial visual inspection with acetic acid (VIA), or vinegar, delivered by primary health workers in a large randomized study conducted among 150,000 women in India. The researchers estimate this...
ASCO 2013: No Increased Risk of Oral HPV Infections Reported in Long-term Partners of Patients with HPV-positive Oropharyngeal Cancers
Spouses and long-term partners of patients diagnosed with human papillomavirus (HPV)-positive oropharyngeal cancer were no more likely to test positive for oral HPV infection than people in the general population and have a low risk of HPV-related oropharyngeal cancer, according to the Human Oral...
Mayo Clinic Genomic Analysis Lends Insight to Prostate Cancer
Mayo Clinic researchers have used next-generation genomic analysis to determine that some of the more aggressive prostate cancer tumors have similar genetic origins, which may help in predicting cancer progression. The findings appear online today in the journal Cancer Research. Gleason Patterns...
Study Establishes Basis for Genomic Classification of Endometrial Cancers
A comprehensive genomic analysis of nearly 400 endometrial tumors suggests that certain molecular characteristics, such as the frequency of mutations, could complement current pathology methods and help distinguish between principal types of endometrial tumors, as well as provide insights into...
The U.S. Supreme Court Hears Arguments Challenging Patents on Breast and Ovarian Cancer Genes
The U.S. Supreme Court heard arguments Monday in a case seeking to invalidate patents on two genes associated with hereditary breast and ovarian cancer. The American College of Medical Genetics and Genomics (ACMG) was one of the first plaintiffs to sign onto this historic legal case. ACMG was also ...
Novel Drug Combination Showed Antitumor Activity in Patients with Incurable BRCA-deficient Cancers
When given sequentially, two orally available experimental drugs—sapacitabine and seliciclib—worked together to elicit antitumor effects in patients with incurable BRCA-deficient cancers, according to phase I data presented at the AACR Annual Meeting 2013, held in Washington, DC, April...
New Drug Target, Companion Prognostic Test for Hormone Therapy–resistant Breast Cancer
A team of international cancer researchers led by Mathieu Lupien, PhD, at the Princess Margaret Cancer Centre, University Health Network, has identified the signaling pathway that is overactivated in estrogen receptor (ER)–positive breast cancer cells that are resistant to hormone therapies...
Mayo Clinic: New DNA Sequences Hone in on Breast, Ovarian Cancer Risk
Researchers at Mayo Clinic Cancer Center have identified new DNA sequences associated with breast cancer and ovarian cancer. The findings, which appear in three studies in the journals PLoS Genetics and Nature Genetics, will help reveal the underlying causes of these diseases and help researchers...
Pathologists Identify Patterns of Mutations to Help Inform Design of Future Trials
Molecular driven therapeutic targets have resulted in a paradigm shift in the treatment of advanced lung adenocarcinoma. However, in early non–small cell lung cancer (NSCLC), surgical resection remains the treatment of choice with adjuvant chemotherapy. In a recent study published in the...
Inherited Genetic Variations Have a Major Impact on Childhood Leukemia Risk
Humans have between 20,000 and 25,000 genes that carry instructions for assembling the proteins that do the work of cells. Work led by St. Jude Children’s Research Hospital found that children who inherit certain variations in four particular genes are at much higher risk of developing acute...
Researchers Identify Variations in Four Genes That Are Associated with an Increased Risk of Colorectal Cancer
An international research team co-led by cancer prevention researcher Ulrike Peters, PhD, MPH, and biostatistician Hsu Li, PhD, at Fred Hutchinson Cancer Research Center has identified variations in four genes that are linked to an increased risk of colorectal cancer. Dr. Peters and...
Inaugural Winners of the Breakthrough Prize in Life Sciences Announced
Founding sponsors Art Levinson, PhD, Sergey Brin, Anne Wojcicki, Mark Zuckerberg, Priscilla Chan, and Yuri Milner announced the launch of the Breakthrough Prize in Life Sciences, recognizing excellence in research aimed at curing intractable diseases and extending human life. The prize will be...
Selumetinib Reported to Benefit Patients with Recurrent Low-grade Ovarian Cancer
Low-grade serous ovarian cancer is less common and aggressive than the high-grade variety, but the disease is exceptionally difficult to treat when front-line therapy fails. "After surgery, with or without presurgical chemotherapy, when low-grade serous ovarian cancer persists or returns,...
Experimental Drug Combination Selectively Destroys Lymphoma Cells
Laboratory experiments conducted by researchers at Virginia Commonwealth University Massey Cancer Center suggest that a novel combination of the investigational agent ibrutinib and bortezomib (Velcade) could potentially be an effective new therapy for several forms of blood cancer, including...
Researchers Discover Mutations Linked to Relapse Of Childhood Leukemia
After an intensive 3-year hunt through the genome, researchers have pinpointed mutations that lead to drug resistance and relapse in acute lymphoblastic leukemia (ALL) ,the most common type of childhood cancer—the first time anyone has linked the disease’s reemergence to specific...
