Cytoskeleton, EarlyView.ABSTRACT Of the three types of cytoskeleton known in animals—actin, microtubules, and intermediate filaments—only actin and microtubules exist in plants. Both play important roles in cellular shaping, organelle movement, organization of the endomembrane system, and cell signaling.

Cytoskeleton, EarlyView.ABSTRACT Elastic tethers connect telomeres of separating chromosomes in anaphase of animal cells. Immunofluorescence staining of titin in crane‐fly spermatocytes, using 4 different antibodies, shows that the giant elastic protein titin seems to be a component of mitotic tethers: titin “strands” extend between separating chromosomes, connecting their ...

Correlation between telomere shortening in maternal peripheral blood and fetal aneuploidy
BMC Pregnancy and ChildbirthBackground This study aimed to assess whether maternal telomere length is a more accurate predictor of trisomy 21 than maternal age while also exploring the factors influencing maternal and fetal telomere length.

Telomere Length Correlates with Life Span of Dog Breeds
Cell Reports, 2012 Telomeric DNA repeats are lost as normal somatic cells replicate. When telomeres reach a critically short length, a DNA damage signal is initiated, inducing cell senescence.

Systemic aging fuels heart failure: Molecular mechanisms and therapeutic avenues
ESC Heart Failure, Volume 12, Issue 2, Page 1059-1080, April 2025.Abstract Systemic aging influences various physiological processes and contributes to structural and functional decline in cardiac tissue. These alterations include an increased incidence of left ventricular hypertrophy, a decline in left ventricular diastolic function, left atrial dilation, atrial fibrillation, myocardial fibrosis and cardiac ...

The Effect of Physical Activity agains the Telomere Length in the Leukocytes Cells of KONI Athletes
Biosaintifika: Journal of Biology & Biology Education, 2017 Telomeres are strands of non coding DNA at the ends of chromosomes that have the primary function to protect DNA from damage and maintain chromosomal stability.

ESC Heart Failure, Volume 12, Issue 2, Page 1455-1463, April 2025.Abstract Aims The extent of irreversible cardiomyocyte necrosis after acute myocardial infarction (AMI) is a major determinant of residual left ventricular (LV) function and clinical outcome. Cell therapy based on CD34+ cells has emerged as an option to help repair the myocardium and to improve outcomes.

Telomere length in sleep disorders
Experimental GerontologySleep and circadian rhythms are affected by aging. Although the relationship between sleep disorders and cellular aging has been demonstrated in some studies, it still remains unclear. Telomere length has been considered one of the sensitive biomarkers for aging in recent years.

Telomere length and cardiovascular disease
Archives of Cardiovascular Diseases, 2010 Telomeres are structures composed of deoxyribonucleic acid repeats that protect the end of chromosomes, but shorten with each cell division. They have been the subject of many studies, particularly in the field of oncology, and more recently their role in the onset, development and prognosis of cardiovascular disease has generated considerable interest.
