[Comparative investigation of antigens associated with plasmatic membranes of rat hepatoma and myogenic cells using anti-kidney serum].
The investigation of antigenic diversion of tumor cells resulting from the expression of heteroorganic antigens has been continued. Tumor-associated heteroorganic antigens with mol. weight 200-210 kDa (identified before as laminin), 105-130, 75-80 and 43 kDa were detected by anti-kidney serum in fractions of plasmatic membranes of cells of rat ascitic Zajdela hepatoma and cultured HTC hepatoma; the antigen 43 kDa was isolated on immunosorbent and identified by mass spectrometry as beta-actin. Anti-kidney serum revealed laminin in fractions of plasmatic membranes of cultured L8 and L6J1 myoblasts, and L6J1 myotubes; apparently, synthesis of laminin by hepatoma and myogenic cells is not connected with their proliferative activity. Besides, anti-kidney serum detected components 38, 42, 44, 48, 62, 78 and 120 kDa, expression of which on myogenic cells surface might be consequence of active cell proliferation and (or) differentiation.
