Absence of a specific ganglioside galactosyltransferase in mouse cells transformed by murine sarcoma virus.
نویسندگان
چکیده
The ganglioside composition of a nonproducer subclone (derived from BALB/c 3T3 mouseembryo cells) transformed by Kirsten murine sarcoma virus was drastically altered compared to the nontransformed parental clone. The transformed clone was unable to synthesize the mono- and disialogangliosides, G(M1) and G(D1a), due to the complete absence of a specific galactosyltransferase. The lack of this enzyme activity was established by sensitive radiochemical and enzymological techniques in vivo and in vitro.

Chemicaly and x-ray-transformed subclones of BALB/c 3T3 mouse embryo cells were found to have reduced amounts of the mono- and disialogangliosides galactosyl-N-acetylgalactosaminyl-[N-acetylneuraminyl]-galactosylglucosylceramide (Gm1) and N-acetylneuraminylgalactosyl-N-acetylgalactosaminyl-[N-acetylneuraminyl]-galactosylglucosylceramide (Gd1a), and increased amounts of N-acetylgalactosaminyl-[N...
متن کاملSpecific antigrowth effect of interferon on mouse cells transformed by murine sarcoma virus.
The growth rate of NIH/3T3 mouse fibroblasts transformed by the Moloney strain of murine sarcoma virus was investigated following interferon (IFN) treatment. These cells were found to be sensitive to the antigrowth effect of IFN as indicated by a slower growth rate in its presence. The effect was most efficiently expressed when cells were grown at low serum concentrations, e.g., 2.5%. Likewise,...

BALB/c embryonic fibroblasts productively transformed by Moloney sarcoma virus and cultivated for over 600 generations in the presence of mouse alpha/beta interferon reverted to an apparently normal phenotype and were unable to produce tumors in nude mice. Nevertheless, the presence of an integrated Moloney sarcoma virus genome in the nonmalignant Moloney sarcoma virus-transformed interferon-tr...
متن کاملSugar effects on murine sarcoma virus transformation.
Transformation of NIH Swiss mouse fibroblasts by a murine sarcoma virus was influenced by the type of carbohydrate in the culture medium. Exposure to D-mannose and 2-deoxy-D-glucose caused a reduction in the number of transformed colonies in vitro and tumor formation in vivo. This is a new type of interference in the transformation process, manifested also by the absence of the pronounced enhan...

Specific rabbit antisera to the major glycoproteins of Friend leukemia virus (gp71) and the mouse mammary tumor virus (gp52) were utilized to study the surfaces of C3H-, DBA-, BALB/c-, and C57BL-transformed and normal cells by immunoelectron microscopy. Antiserum to gp71 showed reactivity with all of the mouse cells tested regardless of strain, virus production, or state of transformation. In c...
