Why Do Mutations for Diseases like Sickle Cell Persist Across Generations? Biologically, We May Be Wired to Keep Them

An evolutionary force, called balancing selection, appears to be responsible for maintaining defects in our DNA associated with diseases, such as sickle cell anemia, because the mutation’s damaging effects might be offset — in a biological way of thinking — by its potential benefits. The study, “Excess of deleterious mutations…

Renal Papillary Necrosis in Sickle Cell Patients Studied in Nigeria

Researchers investigated renal papillary necrosis (RPN), a chronic complication of sickle cell anemia, and found low incidence in South-Eastern Nigerian sickle cell anemia patient cohort, but higher association rates with female patients. The study, “Prevalence and associations of symptomatic renal papillary necrosis in sickle cell anemia patients in South-Eastern Nigeria,” was…

New Mouse Study Suggests Bone Marrow Transplants Safer, More Effective with Antibody-based Treatment

A novel nontoxic transplantation method using antibodies proves safe and effective in treating blood diseases, including sickle cell anemia, according to new research. The study, “Non-genotoxic conditioning for hematopoietic stem cell transplantation using a hematopoietic-cell-specific internalizing immunotoxin,” was published in the journal Nature Biotechnology. Patients with blood disorders,…
