Accelerated features of age-related bone loss in zmpste24 metalloproteinase-deficient mice.
Age-related bone loss is associated with changes in bone cellularity, which include marrow fat infiltration and decreasing levels of osteoblastogenesis. The mechanisms that explain these changes remain unclear. Although nuclear lamina alterations occur in premature aging syndromes that include changes in body fat and severe osteoporosis, the role of proteins of the nuclear lamina in age-related...
متن کاملHeterozygosity for Lmna deficiency eliminates the progeria-like phenotypes in Zmpste24-deficient mice.
Zmpste24 is a metalloproteinase required for the processing of prelamin A to lamin A, a structural component of the nuclear lamina. Zmpste24 deficiency results in the accumulation of prelamin A within cells, a complete loss of mature lamin A, and misshapen nuclear envelopes. Zmpste24-deficient (Zmpste24(-/-)) mice exhibit retarded growth, alopecia, micrognathia, dental abnormalities, osteolytic...
متن کاملBiochemical and phenotypic abnormalities in kynurenine aminotransferase II-deficient mice.
Kynurenic acid (KYNA) can act as an endogenous modulator of excitatory neurotransmission and has been implicated in the pathogenesis of several neurological and psychiatric diseases. To evaluate its role in the brain, we disrupted the murine gene for kynurenine aminotransferase II (KAT II), the principal enzyme responsible for the synthesis of KYNA in the rat brain. mKat-2(-/-) mice showed no d...
متن کاملHistological and biochemical studies of mice kidney after exposure to mobile phone radiation
Introduction: There are general concerns about the hazardous impacts of the cell phones radiation on the human health. In this study, the structural and biochemical changes of the mice kidney were assessed after cell phone exposure in. Materials and methods: A total of 40 Balb/C mice were randomly divided into the control and experimental groups. The experimental group exposed to cell phon...
متن کاملHistological, ultrastructural and biochemical studies on the kidney of mice treated with Carthamus tinctorius L. extract
Objective: Carthamus tinctorius L.(C. tinctorius) is used as a food additive but also has medicinal applications. The present work was designed to investigate its probable side effects on the histology and function of the kidney in the mice. Materials and Methods: Sixty adult Balb/C mice were randomly distributed into one control and three experimental groups. The control group received only di...
