Tumorigenic: DT95細胞Yes

Oncogene: c-myc +

Comments: DT95 is an avian leukosis virus (ALV) induced bursal lymphoma cell line derived from a Hyline SC chicken.

The original lymphoma was induced by viral infection of a 1 day old chicken with Rous associated virus 1 (RAV-1).

Cell suspensions prepared from tumors that developed within the bursa of Fabricus were transferred intravenously into young syngeneic recipient chickens.

After one transfer in vivo, the DT95 cell line was established.

The cell line contains proviral DNA sequences integrated upstream from the c-myc proto-oncogene and expresses increased levels of c-myc RNA.

In vitro, both the c-rel gene and the v-rel oncogenes induce major histocompatibility (MHC) class I, MHC class II, and interleukin-2 receptor (IL-2R) antigens on the DT95 cell line.

The expression of MHC class II is induced more rapidly by v-rel than c-rel and several weeks after infection, rel induced class II antigen as much as 50 fold more efficiently than c-rel.

The cell line exhibits a more differentiated plasmacytoid phenotype than DT40 (see ATCC CRL-2111).

Infectivity assays revealed that DT95 does not release infectious RAV-1.
