Study identifies novel IgAN loci through pleiotropy

IgA nephropathy (IgAN) is a prevalent form of primary glomerulonephritis characterized by the deposition of IgA in the glomerular mesangium, leading to a spectrum of histopathological lesions and a variable clinical course that can progress to end-stage renal disease in a significant proportion of patients.

Mayo Clinic researchers advocate for comprehensive TPMT genotyping across ancestries

Mayo Clinic researchers found that a gene variant, the TPMT∗8 allele, is associated with reduced metabolism of the thiopurine class of drugs. TPMT∗8 is relatively common in individuals of African or African American descent. A novel study in The Journal of Molecular Diagnostics, published by Elsevier, details the researchers' goal to provide pharmacogenomic testing that can be used clinically to predict drug response that is beneficial to all patients, regardless of their ancestral background.

Early ovarian removal and APOE4 increase Alzheimer's risk in women

New research published by a team of researchers from the University of Toronto in collaboration with colleagues from the University of Alberta has found that women who have had both ovaries surgically removed before the age of 50 and carry a variant of the apolipoprotein gene, the APOE4 allele, are at high risk of late-life Alzheimer disease (AD). Use of hormone therapy mitigates this risk.

3D tumor mapping reveals new insights into cancer biology and treatment

A new analysis led by researchers at Washington University School of Medicine in St. Louis has revealed detailed 3D maps of the internal structures of multiple tumor types. These cancer atlases reveal how different tumor cells - and the cells of a tumor's surrounding environment - are organized, in 3D, and how that organization changes when a tumor spreads to other organs.
