Ethnic disparities in the occurrence of prostate cancer

May 10, 2018 – A seemingly higher incidence of prostate cancer and resulting fatalities in African-American men than in European-Amcerican men has been noted for quite some time. New research published in Molecular Oncology may help explain why African American men are at a higher risk of being diagnosed with prostate cancer and a higher risk of dying from the disease compared with European American men.

Gene expression and ethnicity: Does it matter?

December 05, 2017 – We are entering the age of precision medicine, in which diagnosis and therapy decisions for each patient will be based on detailed genetic and molecular fingerprints. Unfortunately, much of the revolutionary work that underpins precision medicine has been conducted on populations of European (Caucasian) descent,

Cancer is not like cancer: Ethnic background matters

November 24, 2017 – New research indicates that one-size treatment for one form of blood cancer likely does not fit all, particularly when it comes to ethnic differences of patients.  Thus, African-American men are three times more likely to be diagnosed with multiple myeloma,

SEMA4D gene variant quadruples obesity risk in individuals of African descent

March 26, 2017 – There is ample evidence that the burden of obesity is not the same across ethnic groups. While diet and lifestyle play a large role in determining body weight, there is also a heritable component. Unfortunately,  most prior studies that have evaluated the role of genes in obesity have looked mostly at people of European or Asian descent,

Adverse clinical outcome associated with mutations in colorectal cancers of African Americans

Colon Cancer in AASeptember 04, 2016 – Case Comprehensive Cancer Center researchers, a research collaboration which includes University Hospitals Seidman Cancer Center and Case Western Reserve University, who last year identified new gene mutations unique to colon cancers in African Americans, have found that tumors with these mutations are highly aggressive and more likely to recur and metastasize.

  • Researchers identify new gene mutation in familial thyroid cancers November 20, 2019
    Researchers from Penn State College of Medicine identified a new gene mutation that may cause a type of familial thyroid cancer. Dr. Darrin Bann, an otolaryngology resident at the College of Medicine and lead author of the study, said that this mutation is the first and only mutation associated with familial thyroid cancer to be […]
  • Researchers develop new database of druggable fusion targets November 20, 2019
    When sections from two separate genes merge due to various factors, such as translocation or splicing, the hybrid that is formed is called a gene fusion. In recent years, it has been discovered that these fusion events play a vital role in the development of cancers and other complex diseases. However, there are very few […]
  • Early results of CRISPR gene-editing treatment shows promise in first human trials November 20, 2019
    Officials from Vertex Pharmaceuticals and CRISPR Therapeutics have announced that preliminary results from testing CRISPR gene-editing treatment in human patients with blood disorders show promise thus far. The joint project between the two firms is taking place at one location in Europe and another in the United States. The results have been posted on the […]
  • Whole-genome sequencing analysis to find more exact biomarkers November 20, 2019
    A new study from Uppsala University shows that whole-genome sequencing increases the precision of genetic studies, which in turn can improve our understanding of how to use biomarkers to discover disease. The results are published in the scientific journal Scientific Reports.
  • Complex organ models grown in the lab November 19, 2019
    Scientists at the University of Würzburg have successfully produced human tissues from stem cells. They have a complexity similar to that of normal tissue and are far superior to previous structures.
  • New study confirms American children and teens are consuming significantly less sugary drinks November 21, 2019
    According to a new study in the American Journal of Preventive Medicine, published by Elsevier, the share of children and adolescents consuming sugar-sweetened beverages (SSBs) and the calories they consume from SSBs declined significantly between 2003 and 2014.
  • New Alzheimer risk gene discovered November 21, 2019
    A new paper in the Journal of Neuropathology & Experimental Neurology finds a gene that may help explain a large part of the genetic risk for developing Alzheimer disease.
  • New type of e-cigarette vaping injury described in CMAJ November 21, 2019
    A research case report describing lung injury related to e-cigarette use in a 17-year-old Canadian may be the first documented case of a new form of damage from vaping products. The article, published in CMAJ (Canadian Medical Association Journal) provides new evidence on forms of lung injury that can result from vaping.
  • CUHK Faculty of Engineering develops novel imaging approach November 21, 2019
    By combining a compressive sensing algorithm with a digital holographic microscope, Prof. Shih-Chi CHEN of the Department of Mechanical and Automation Engineering, Faculty of Engineering, The Chinese University of Hong Kong (CUHK) and his research team have developed a high-speed imaging method. The new approach is able to produce two-photon microscopy images of a 3D […]
  • Cybershoppers make better buying decisions on PCs than phones -- Ben-Gurion U. researchers November 21, 2019
    This is the first study that differentiates between screen size and information reduction, which are often mixed up. The findings will be presented next month at the International Conference on Information Systems, the top academic conference in the field.
