Diabetes during pregnancy causes an intrauterine environment that influences lifetime sickness of the mother and the fetus. There is a correlation between diabetes and telomere shortening; however, very little is known about telomere homeostasis in the placenta. We aimed to study the telomerase complex in placentas and in cord blood leukocytes from patients with poorly controlled diabetes.Biopsies...
Telomeres are nucleoprotein structures, essential for chromosome stability and cell survival. Telomeres are progressively shortened with each cell division and by environmental factors. Telomere loss has been linked to age and stress-induced premature senescence. Dysfunctional telomeres tend to form aggregates, which consist of the end-to-end fusion of telomeres. Telomere elongation is carried out...
Genomic aneuploidy is a common cause of human genetic disorders. Individuals with aneuploidy tend to develop malignancies. Recent studies correlated aneuploidy with early aging, senescence and organ dysfunction. This study investigated potential explanations for these increased risks by evaluating random aneuploidy and senescence rates in amniocytes from fetuses with aneuploidy.The rates of random...
