Structural organization of murine intracisternal A particles.
Isolated murine intracisternal A particles have a distinctive set of structural properties as compared to the recognized oncogenic ribonucleic acid tumor viruses. A particles consist of two closely approximated concentric shells. The outer shell is largely, but not entirely, susceptible to treatment with detergents such as deoxycholate and Triton X-100. The inner shell is resistant to these age...
متن کاملIntracisternal type A particles occurring in foreign body-induced sarcomas.
Eight sarcomas induced in mouse strains CBA/H, CBA/HT6, and C57BL/10ScSn (or their hybrids) by s.c. implantation of smooth or roughened plastic films or glass pieces were examined electron microscopically. Type A virus particles were detected within dilated ergastoplasmic cisternae of the sarcoma cells from five mice. The doughnut-shaped particles measured 90 to 100 nm and were seen to bud from...

15 صفحه اولIntracisternal A particles: RNA expression and DNA methylation in murine teratocarcinoma cell lines.
Two main intracisternal-A-particle-specific RNA species (29 to 30S and 35 to 36S) are variably expressed in particle-producing and particle-nonproducing murine teratocarcinoma cell lines. An analysis of DNA methylation patterns after hybridization with an intracisternal-A-particle-specific probe showed an apparent direct correlation between DNA methylation and RNA expression. However, when the ...
