The aims of this study were to investigate the impact of caloric restriction (CR) on cardiac senescence in an animal model of diabetes and examine the signal transduction mechanisms for changes in cell survival as well as cardiac function. Male 8-week-old Otsuka Long-Evans Tokushima fatty (OLETF) diabetic rats were divided into 2 groups: a group fed ad libitum (AL), and a group fed with CR (30% energy reduction). Long-Evans Tokushima Otsuka (LETO) non-diabetic rats were used as controls.

We explored the association of fecal bacterial species and somatic telomere changes in patients with chronic disease. The results showed that the length of the combined range of telomere and the methylated subtelomere was correlated with the increase of bacteria species and the numerical superiority of certain strains in feces, the increase of streptococci in men and women, and the increase of E. coli specifically in women.

Biological aging underlies lifestyle-related diseases. It can be assessed by measuring personal somatic cell telomere length. However, measuring the telomere length is laborious, and its clinical surrogate parameters have not been developed.

Telomere shortening is well known to be associated with the aging process and aging-associated diseases, including diabetes. The telomere length and subtelomeric methylation status in peripheral leucocytes (LTL) were compared in elderly type 2 diabetes (T2D) patients and diabetes-free controls (C). The methylation status was analyzed between MspI-TRF lengths and HpaII-TRF lengths by using methylation-sensitive and -insensitive restriction enzyme isoschizomers, MspI and HpaII, respectively.

Furthermore, the sarcoplasmic reticular Ca uptake and release activities were reduced and Ca influx through L-type Ca channels was increased in the atrophied heart. Since Ca movements at sarcolemma are intimately involved in the regulation of intracellular Ca concentration, the present study was undertaken to test if sarcolemma plays any role to maintain cardiac function in the atrophied heart.

Furthermore, we have reported that the telomere length of a sub-healthy population also correlates with the blood data of laboratory tests. These facts suggest that patients with shorter telomere length tend to be hospitalized more easily than patients with longer telomere length.

To clarify this issue, an epidemiological questionnaire study regarding personal hot spa-bathing habits and disease history was carried out in Japan, where individuals engage in daily warm water bathing. Questionnaires regarding hot spa-bathing habits and disease history were randomly sent to 20,000 residents aged ≥65 years living in Beppu, a city in Japan that has the highest concentration of hot spa sources in the world.

Methods: In this study we investigated the beneficial effects of epigallocatechin gallate (EGCG) on the cardiac remodeling and telomere biology in H/M-SOD2 mice. H/M-SOD2 mice were divided into three groups: those receiving normal drinking water (KO), a low dose of EGCG (L: 10mg/L), and a high dose of EGCG (H: 100mg/L) beginning at eight weeks of age and lasting for eight weeks.

The loss of a few hundred base pairs from a shortened telomere has been shown to be important with respect to cellular senescence, although it may not be detected according to traditional mean telomere length [assessed as the terminal restriction fragment (TRF)] analyses. In the present study, a continuous time window from irradiation was selected to examine changes in the telomere length, including the mean TRF length, percentage of the telomere length, telomerase activity, apoptotic rate, and survival rate in HUVECs from the first day to the fourth day after the administration of a 0.

This study was designed to identify changes in telomere length and telomerase activity in human umbilical vein endothelial cells (HUVECs) exposed to various levels of hypoxia. Mild hypoxia (10%, 15% oxygen) increased telomere length, which did not appear to change under severe hypoxia (1% oxygen). Telomerase activity in HUVECs correlated inversely with oxygen concentration.

Methods: The telomeric changes and the alterations of the expression of telomere-associated proteins in human umbilical venous endothelial cells (HUVEC) cultured in the presence of hydrogen peroxide (H2 O2 ) were analyzed.

Telomere shortening has been reported to be related to oxidative stress (OS) associated with the aging process and aging-associated diseases, including Alzheimer's disease (AD). We measured the methylated and non-methylated telomere lengths in the peripheral blood mononuclear cells of 34 AD patients and 49 healthy controls by a Southern blotting analysis, using methylation-sensitive and - insensitive restriction enzyme isoschizomers, MspI and HpaII. AD patients bore normal mean telomere lengths and had an unchanged distribution of the telomere length in peripheral leukocytes.
