Telomere Length and Aging
Telomeres, the TTAGGG tandem repeats at the ends of chromosomes, become progressively shortened with each replication of cultured human somatic cells (reviewed in Wong and Collins (Wong & Collins 2003)) until a critical length is achieved, at which point the cell enters replicative senescence. This situation can be reversed by the enzyme named telomerase that is responsible for Telomere Length ...
متن کاملLeukocyte telomere length: the telomere tale continues.
In culture, replicating human somatic cells display progressive telomere shortening. Ultimately, such cells either undergo apoptosis or enter a state of replicative senescence that is triggered by critically shortened telomeres. Accordingly, telomere length is an index of both the replicative history and the replicative potential of human somatic cells in culture (1). Most replicating human som...
متن کاملTelomere length and reproductive aging
BACKGROUND Rate of reproductive aging may be related to rate of biological aging. Thus, indicators of aging, such as short telomere length, may be more frequent in women with a history suggestive of premature reproductive senescence. METHODS Telomere-specific quantitative PCR was used to assess telomere length in two groups of women with evidence of reproductive aging: (i) patients with idiop...
متن کاملTSPY and Male Fertility
Spermatogenesis requires the concerted action of thousands of genes, all contributing to its efficiency to a different extent. The Y chromosome contains several testis-specific genes and among them the AZF region genes on the Yq and the TSPY1 array on the Yp are the most relevant candidates for spermatogenic function. TSPY1 was originally described as the putative gene for the gonadoblastoma lo...
متن کاملHypertension and Male Fertility
As the age of paternity rises in the developed world, issues of chronic disease may affect prospective fathers. Given the high prevalence of hypertension, researchers have begun to explore the relationship between hypertensive disease and male fertility. The current literature suggests an association between hypertension and semen quality. The use of various antihypertensive medications has als...
