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.

  • Findings in mice reveal possibilities for fetal drug therapy for deafness April 6, 2020
    New research led by hearing scientists at Oregon Health & Science University suggests an avenue to treat and prevent intractable genetic disorders before birth.
  • Study of rare genetic disorder that effects the eyes April 3, 2020
    Nagano prefecture is home to a group of people affected with a rare genetic neurodegenerative disorder called familial amyloid polyneuropathies (FAP). This disease impacts the gene encoding protein transthyretin (TTR) which is produced in the liver and also eyes. Liver transplants are often a treatment for this disease, but severe eyesight problems such as cloudiness […]
  • Natural sunscreen gene influences how we make vitamin D April 2, 2020
    Genetic variations in the skin can create a natural sunscreen, according to University of Queensland researchers investigating the genes linked with vitamin D.
  • Single mutation leads to big effects in autism-related gene April 2, 2020
    A new study in Neuron offers clues to why autism spectrum disorder (ASD) is more common in boys than in girls. National Institutes of Health scientists found that a single amino acid change in the NLGN4 gene, which has been linked to autism symptoms, may drive this difference in some cases. The study was conducted […]
  • Lifestyle changes could delay memory problems in old age, depending on our genes April 2, 2020
    Researchers from King's College London have shown that how we respond to changes in nutrients at a molecular level plays an important role in the aging process, and this is directed by some key genetic mechanisms.
  • Study of rare genetic disorder that effects the eyes April 3, 2020
    Small gauge vitrectomy for vitreous amyloidosis and subsequent management of secondary glaucoma in patients with hereditary transthyretin amyloidosis.
  • Tissue dynamics provide clues to human disease April 3, 2020
    Scientists in EMBL Barcelona's Ebisuya group, with collaborators from RIKEN, Kyoto University, and Meijo Hospital in Nagoya, Japan, have studied oscillating patterns of gene expression, coordinated across time and space within a tissue grown in vitro, to explore the molecular causes of a rare human hereditary disease known as spondylocostal dysostosis. Their results are published […]
  • Coronavirus: Virological findings from patients treated in a Munich hospital April 3, 2020
    In early February, research teams from Charité - Universitätsmedizin Berlin, München Klinik Schwabing and the Bundeswehr Institute of Microbiology published initial findings describing the efficient transmission of SARS-CoV-2. The researchers' detailed report on the clinical course and treatment of Germany's first group of COVID-19 patients has now been published in Nature*. Criteria may now be […]
  • Case study: Treating COVID-19 in a patient with multiple myeloma April 3, 2020
    A case study of a patient in Wuhan, China, suggests that the immunosuppressant tocilizumab may be an effective COVID-19 treatment for very ill patients who also have multiple myeloma and other blood cancers. The report, published in Blood Advances, also suggests that blood cancer patients may have atypical COVID-19 symptoms.
  • Indigenous American ancestry may be associated with HER2-positive breast cancer April 3, 2020
    An increased proportion of Indigenous American (IA) ancestry was associated with a greater incidence of HER2-positive breast cancer, according to a study published in Cancer Research, a journal of the American Association for Cancer Research.
