چکیده

Systemic oxidative stress is considered to cause aging. In this study, to estimate the oxidative stress level in senescence-accelerated mouse prone 8 (SAMP8), we evaluated serum reactive oxygen species production and reduction capacity by measurement of Diacron-Reactive Oxygen Metabolites (d-ROM) and Biological Antioxidant Potential (BAP), respectively, with age. SAMP8 showed earlier increase of d-ROM value with age than SAM resistant 1 (SAMR1), the control strain. The BAP level was the highest in adult SAMP8, whereas SAMR1 presented the sustained BAP values between ages. These results indicate that oxidative stress in SAMP8 is higher than SAMR1. Our study is the first detailed report about d-ROM and BAP in SAMP8 and will provide useful fundamental data for future aging studies.

In Vitro Evaluation of Protective Effect of Rutin on Acrylamide-Induced Cellular Senescence in NIH3T3 Cells

Background: Aging is one of the important factors in the development of age-related diseases. Acrylamide can be produced during carbohydrate-rich foods prepared at high temperatures. Recently, studies showed that acrylamide can induce cellular senescence. On the other hand, Rutin as a natural flavonoid, has a potent antioxidant activity. Objective: This study aims to evaluate the ptotective ef...

Effects of collagen hydrolysate on the tibialis anterior muscle and femur in senescence-accelerated mouse prone 6

OBJECTIVES Effects of collagen hydrolysate (CHD) on the oxidative capacity of the tibialis anterior muscle and the cortical and trabecular density of the femur were investigated in senescence-accelerated mouse prone 6 (SAMP6). METHODS Sixteen-week-old male SAMP6 mice were divided into control (CON) and CHD groups. The CON group was given normal water, while the CHD group was given water conta...

Data on the optimization of behavioral tasks for senescence-accelerated mouse prone 8 (SAMP8)

This data article contains the supporting information for the research article entitled "Early onset of behavioral alterations in senescence-accelerated mouse prone 8 (SAMP8)" [1]. Senescence-accelerated mouse prone 8 (SAMP8), which originally developed from AKR/J mice, shows learning and memory impairments at the age of 8-12 months. However, little information is still available on phenotypica...

Cultured murine dermal fibroblast-like cells from senescence-accelerated mice as in vitro models for higher oxidative stress due to mitochondrial alterations.

The senescence-accelerated mouse is a model for senescence acceleration, a higher oxidative stress status, and age-associated disorders. We studied whether fibroblasts cultured from accelerated senescence-prone SAMP11 mice could be used as in vitro models for oxidative stress in senescence. Dichlorofluorescein and hydroethidine assays demonstrated that cells from SAMP11 mice produced more react...

Antisense directed at the Abeta region of APP decreases brain oxidative markers in aged senescence accelerated mice.

Amyloid beta-peptide (Abeta) is known to induce free radical-mediated oxidative stress in the brain. Free radical-mediated damage to the neuronal membrane components has been implicated in the etiology of Alzheimer's disease (AD). Abeta is produced by proteolytic processing of the amyloid precursor protein (APP). The senescence accelerated mouse prone 8 (SAMP8) strain was developed by phenotypi...
