[Anti-aging studies on the senescence accelerated mouse (SAM) strains].
Senescence accelerated mouse (SAM), a murine model of accelerated senescence, was established by Toshio Takeda and colleagues. SAM consists of series of SAMP (prone) and SAMR (resistant) lines. All SAMP lines (from SAMP1 to SAMP11) are characterized by accelerated accumulation of senile features, earlier onset and faster progress of age-associated pathological phenotypes, such as amyloidosis, i...
متن کاملBiochemical characteristics of lungs in senescence-accelerated mouse (SAM).
This study examined age-related biochemical changes of the lung in an animal model of senile lung, senescence-accelerated mouse (SAM). Bronchoalveolar lavage (BAL) was performed on two strains of SAM, the senescence-prone strain (SAM P2) and the senescence-resistant strain (SAM R1), as well as on normal ageing C57 black mice (C57BL), aged 1-24 months. Elastase-like and elastase inhibitory activ...
متن کاملHepatic gene expression changes in an experimental model of accelerated senescence: the SAM-P8 mouse.
The senescence-accelerated mouse (SAM) is an experimental model of aging, established through phenotypic selection from a common genetic pool of AKR/J mice. Here we use complementary DNA microarray, Western blot, and electrophoretic mobility shift assay to consider whether changes in liver gene expression observed in 5-month-old SAM-prone 8 (P8) mice, compared to SAM-R1 controls, are similar to...
متن کاملCharacterization of Senescence-Accelerated Mouse Prone 6 (SAMP6) as an Animal Model for Brain Research
The senescence-accelerated mouse (SAM) was developed by selective breeding of the AKR/J strain, based on a graded score for senescence, which led to the development of both senescence-accelerated prone (SAMP), and senescence-accelerated resistant (SAMR) strains. Among the SAMP strains, SAMP6 is well characterized as a model of senile osteoporosis, but its brain and neuronal functions have not b...
متن کاملInfluences of inhaled tobacco smoke on the senescence accelerated mouse (SAM).
We studied the influences of inhaled tobacco smoke on lung structure, biochemical changes in bronchoalveolar lavage (BAL) fluid, and glutathione (GSH) content of the lung in the senescence accelerated mouse (SAM), using 30 female SAM-P/8 as the "senescence-prone series", compared with SAM-R/1 as the "senescence-resistant series". At 18 wks of age, half of each series were housed in Hamburg II m...
