Effect of Testosterone Treatment on Leucocyte Telomere Length in Men: Results From a Randomised Placebo‐Controlled Trial

open access: yesAndrology, EarlyView.
ABSTRACT Background Lower testosterone concentrations in older men are associated with poorer health outcomes. Objective We examined whether, on a background of lifestyle intervention, testosterone treatment modulates leucocyte telomere length, a postulated marker of biological ageing, in overweight men with impaired glucose tolerance (IGT) or newly ...

Bone Health and Aging in Klinefelter Syndrome

open access: yesAndrology, EarlyView.
ABSTRACT Klinefelter syndrome (KS) is typically diagnosed in young adults, but advances in prenatal testing have led to its recognition at a much earlier age. Conversely, diagnosis in late adulthood remains uncommon, but still occurs. Independently from the age at diagnosis, KS individuals now receive more accurate and tailored care management than in ...

A genetic and historical perspective on the origins of keratitis fugax hereditaria

open access: yesActa Ophthalmologica, EarlyView.
Abstract Purpose To investigate the genetic and genealogical background of keratitis fugax hereditaria (KFH), a periodic corneal disease caused by the heterozygous pathogenic variant c.61G>C in the NLRP3 gene. KFH is characterized by recurrent unilateral autoinflammatory attacks alternating between the eyes and permanent corneal opacities.

Distinct clinical and genetic characteristics of myelodysplastic syndrome in younger patients

open access: yesBritish Journal of Haematology, EarlyView.
Summary Myelodysplastic neoplasms (formerly myelodysplastic syndromes, MDS) are heterogeneous clonal haematological malignancies that primarily affect the elderly, though a notable proportion of patients are diagnosed at younger ages. We retrospectively analysed 1437 patients diagnosed or treated at Asan Medical Center between 1989 and 2022, comparing ...

Are Drosophila telomeres an exception or the rule?

open access: yes, 2002
At the ends of eukaryotic chromosomes are telomeres, specialized structures with unusual properties. Specific efforts to compare sequences and properties of telomeres across species can reveal the generalities of telomere ...

ALT phenotype assessment in IDH‐mutant astrocytoma supports biologic consequence of ATRX missense mutations

open access: yesBrain Pathology, EarlyView.
A meaningful subset of IDH‐mutant astrocytoma harbors ATRX missense variants that retain ATRX IHC immunoreactivity yet exhibit functional ALT activation, supporting the biologic relevance of these missense mutations.

Ionizing Radiation and Ultraviolet Light Irradiation‐Associated DNA Damage Increasing Genomic Instability Risk

open access: yesCancer Science, EarlyView.
UV irradiation induces two major types of pyrimidine dimers, CPDs and 6–4PPs. Whereas 6–4PPs efficiently induce cell‐cycle arrest, CPDs do not and frequently persist into S phase. As a result, DSBs can arise in the presence of unrepaired CPDs after 6–4PPs have been repaired, increasing the risk of genomic instability.
