Cell-density-dependence for growth in agarose of two human lymphoma lines and its decrease after Epstein-Barr virus conversion.

We have compared the growth in agarose medium of two EBV-negative Burkitt lymphoma lines, BJAB and Ramos, and that of their EBV-converted derivatives. Optimal conditions for growth in agarose medium are described. The original EBV-negative lines can grow in agarose to a high efficiency, provided a critical level of cell concentration is attained. Below this level, there is no growth at all. EBV-converted sublines form colonies at a much lower cell concentration, and their maximal plating efficiency is higher. These differences may be related to a super-transformation state induced in these cells by EBV.

Burkitt Lymphoma

[Cytotoxic and antitumor activity of a new series of heterocyclic compounds: dipyrido (4,3-b) (3,4-f) indoles].

Among newly synthesized compounds derived from the dipyrido [4,3-b] [3,4-f] indole nucleus, two have proved to be particularly active in vitro and in vivo. Their cytotoxic effects on cultured cells have been determined. At non toxic doses, they displayed a pronounced inhibitory effect on experimental L1210 Leukemia. These compounds have a strong affinity for DNA molecules.
