Previously we established cell lines resistant to Adriamycin and cisplatin to elucidate the mechanisms involved in acquired drug-resistance. In this study, we investigated ganglioside composition in drug-resistant cell lines. The Adriamycin-resistant cell line, SBC-3/ADM100, exhibited a ganglioside composition ratio similar to that of the parent SBC-3 cells. Densitometric analysis by resorcinol showed a 1.61-fold increase of ganglioside GM2 in SBC-3/ADM100 cells, when compared to the parent SBC-3 cells. The cisplatin-resistant cell line, SBC-3/CDDP, showed a simplified ganglioside pattern, expressing only gangliosides GM3 and GM2. SBC-3/CDDP cells showed a marked increase in ganglioside GM3. These findings suggest that the alteration of ganglioside composition may be actively involved in the acquisition of drug-resistance.

D002945 Cisplatin An inorganic and water-soluble platinum complex. After undergoing hydrolysis, it reacts with DNA to produce both intra and interstrand crosslinks. These crosslinks appear to impair replication and transcription of DNA. The cytotoxicity of cisplatin correlates with cellular arrest in the G2 phase of the cell cycle.

D005434 Flow Cytometry Technique using an instrument system for making, processing, and displaying one or more measurements on individual cells obtained from a cell suspension. Cells are usually stained with one or more fluorescent dyes specific to cell components of interest, e.g., DNA, and fluorescence of each cell is measured as it rapidly transverses the excitation beam (laser or mercury arc lamp). Fluorescence provides a quantitative measure of various biochemical and biophysical properties of the cell, as well as a basis for cell sorting. Other measurable optical parameters include light absorption and light scattering, the latter being applicable to the measurement of cell size, shape, density, granularity, and stain uptake.

D005678 G(M2) Ganglioside A glycosphingolipid that accumulates due to a deficiency of hexosaminidase A or B (BETA-N-ACETYLHEXOSAMINIDASES), or GM2 activator protein, resulting in GANGLIOSIDOSES, heredity metabolic disorders that include TAY-SACHS DISEASE and SANDHOFF DISEASE.

D005679 G(M3) Ganglioside A ganglioside present in abnormally large amounts in the brain and liver due to a deficient biosynthetic enzyme, G(M3):UDP-N-acetylgalactosaminyltransferase. Deficiency of this enzyme prevents the formation of G(M2) ganglioside from G(M3) ganglioside and is the cause of an anabolic sphingolipidosis.
