Age-dependent and tissue-specific structural changes in the C57BL/6J mouse genome.

Abstract:

:We tested the hypothesis that structural changes in the genome parallel age- and organ-specific phenotypes in conjunction with the differential transposition activities of retroelements. The genomes of the liver from C57BL/6J mice were larger than other organs, coinciding with an increase in genomic copies of certain retroelements. In addition, there were differential increments in the genome size of the liver with increasing age, which peaked at 5 weeks. The findings that the genome structure of an individual is variable depending on age and organ type in association with the transposition of retroelements may have broad implications in understanding biologic phenomena.

  • Annexin A3 is associated with a poor prognosis in breast cancer and participates in the modulation of apoptosis in vitro by affecting the Bcl-2/Bax balance.

    abstract:OBJECTIVE:Annexins are a family of intracellular proteins that bind membrane phospholipids in a Ca(2+) concentration-dependent manner. Several annexins play important roles during tumor progression. However, little is known about the clinical implications and biological functions of Annexin A3 in breast cancer. METHOD...
