AI Article Synopsis
- The study investigated how genetic abnormalities and shorter telomere lengths could help assess the prognosis of individuals with myelodysplastic syndrome (MDS).
- It involved analyzing 49 genes and measuring telomere length in 46 subjects, revealing a mutation frequency that increased with higher risk categories of the International Prognostic Scoring System (IPSS-R).
- While shorter telomere length was found in a significant portion of participants, it did not strongly correlate with MDS prognosis but might assist in reclassifying those considered non-high-risk.
Article Abstract
Objective: We aimed to evaluate the clinical usefulness of genetic aberration and shorter telomere length (TL) in individuals with myelodysplastic syndrome (MDS).
Methods: A targeted sequencing panel with 49 genes and TL measurement by quantitative real-time polymerase chain reaction were performed for 46 subjects.
Results: According to the revised International Prognostic Scoring System (IPSS-R) subtypes, the mutation frequency was 33.3%, 57.9%, and 100% in the very low/low, intermediate, and very high/high risk groups, respectively. A shorter telomere was detected in 43.5%. We defined group 1 as IPSS-R-high or -very high risk, group 2 as having 1 or more genetic aberrations, group 3 as having a shorter TL, and group 4 as having a longer TL than the age-matched reference. Group 1 and group 2 showed an adverse prognosis. The TL was not strongly correlated with MDS prognosis. However, it may be related to a poor long-term prognosis.
Conclusion: Genetic variation and shorter TL may be helpful in reclassifying non-high-risk groups.

Clonal hematopoiesis of indeterminate potential (CHIP) is associated with increased mortality and malignancy risk, yet the determinants of clonal expansion remain poorly understood. We performed sequencing at >4,000x depth of coverage for CHIP mutations in 6,986 postmenopausal women from the Women's Health Initiative at two timepoints approximately 15 years apart. Among 3,685 mutations detected at baseline (VAF ≥ 0.

Telomere length (TL) is considered a biomarker of aging, and short TL in leukocytes is related to age and stress-related health problems. Cumulative lifetime stress exposure has also been associated with shorter TL and age-related health problems, but the mechanisms are not well understood. We tested in 108 individuals whether shorter TL in leukocytes is observed in individuals with the GABRA6 TT genotype, which has been associated with dysregulation of hypothalamic-pituitary-adrenal axis activity (the main biological stress system) compared to the CC genotype.

Background: Autism spectrum disorder (ASD) has been reported to confer an increased risk of natural premature death. Telomere erosion caused by oxidative stress is a common consequence in age-related diseases. However, whether telomere length (TL) and oxidative indicators are significantly changed in ASD patients compared with controls remains controversial.

Background And Aim: Telomere length (TL) is a key biomarker of cellular aging, with shorter telomeres associated with age-related diseases. Lifestyle interventions mitigating telomere shortening are essential for preventing such conditions. This study aimed to examine the effects of two weight loss dietary strategies, based on a moderately high-protein (MHP) diet and a low-fat (LF) diet on TL in individuals with overweight or obesity.

In most Eukaryota, telomeres are protected by the CST complex, composed of CTC1, STN1 and TEN1. In Drosophila, instead, another complex is present, composed of Modigliani, Tea and Verrocchio. We performed a search for STN1 orthologs in Arthropoda, in order to verify if Verrocchio can be considered as such.
