The rat mRNA is encoded by a simple two-exon transcription unit. Sequence analysis of the region upstream of the transcription start-site did not reveal a typical TATA-box consensus sequence. Low levels of CNTF mRNA were detected in cultured Schwann cells, and CNTF mRNA was not increased by a variety of treatments. Three-week-old astrocyteenriched cell cultures from new-born rat brain contained easily detectable CNTF mRNA. In astrocyte-enriched cultures, upregulation of CNTF mRNA levels was observed after treatment with IFN-gamma. CNTF mRNA levels were down-regulated in these cells by treatments that elevate intracellular cyclic AMP and by members of the fibroblast growth factor (FGF) family. The implications of these results for potential in vivo functions of CNTF are discussed.}, language = {en} } @article{SendtnerStoeckliCarrolletal.1992, author = {Sendtner, Michael and St{\"o}ckli, Kurt A. and Carroll, Patrick and Kreutzberg, Georg W. and Thoenen, Hans}, title = {More on motor neurons}, url = {http://nbn-resolving.de/urn:nbn:de:bvb:20-opus-42598}, year = {1992}, abstract = {No abstract available}, language = {en} } @article{StoeckliLottspeichSendtneretal.1989, author = {St{\"o}ckli, K.

In cultures of dissociated sympathetic neurons from newborn rats, CNTF induces cholinergic differentiation as shown by increased levels of choline acetyltransferase (ChAT.}, language = {en} }
