title: Cell cycle dependency of tumor antigens.
abstract: There is now substantial evidence that suggests that tumor antigen expression is cell cycle dependent. This information has been obtained from a wide variety of tumor systems. The G1 phase of the cell cycle has been implicated by a number of investigators as the point of maximal antigen appearance. In this presentation, we are concerned with a human sarcoma-associated tumor antigen and its cell cycle-dependent appearance. Sarcoma-associated tumor antigen is a membrane antigen present on cultured human neurosarcoma cells (T2-cells). Although the underlying mechanisms responsible for cell cycle-dependent expression are unclear, several possible interpretations are offered.
