The half-lives of c-fos mRNA are generally very short; they increase from 14 min (after 30 min of culture) to 70 min (after 2 h of culture). The half-lives of c-myc mRNA decrease from 50 min (at 2 and 6 h post stimulation with concanavalin A) to 12 min (at 48 h post stimulation). The c-fos gene transcription is already tumed on in time-0 lymphocytes 10 min after disruption of the organ structure of the spleens and is down-regulated after 2 h and later. In nuclear run-on experiments with nonstimulated lymphocytes there is already significant transcription of the first exon of c-myc, but almost no elongation of the transcript to exon 2 and 3. In concanavalin A-treated lymphocytes elongation is stimulated about 5-fold within 6 h and returns to background levels at 48 h post Stimulation. ยท The nuclear run-on analyses of nonactivated lymphocytes showed a signal for RNA complementary to c-myc mRNA detected with a probe specific for the exon 1/intron 1 boundary of c-myc, which disappeared with increasing time of concanavalin A Stimulation. This anti-sense transcription may play a role in regulating the elongation of cmyc transcripts.}, subject = {Lymphozyt}, language = {en} } @article{SchneiderSchauliesKnauerHuenigetal.1984, author = {Schneider-Schaulies, J{\"u}rgen and Knauer, R. and H{\"u}nig, T. and Schimpl, A. and Wecker, E.}, title = {Induction of c-onc expression in polyclonally activated mouse lymphocytes}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-54784}, year = {1984}, abstract = {No abstract available}, subject = {Lymphozyt}, language = {en} } @article{SchneiderSchauliesKnauerSchimpletal.1987, author = {Schneider-Schaulies, J{\"u}rgen and Knauer, R. and Schimpl, A. and Wecker, E.}, title = {Cellular Oncogenes and lymphocyte activation}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-54836}, year = {1987}, abstract = {No abstract available}, subject = {Lymphozyt}, language = {en} }
