276, 44365-44368) that IFN-beta induction of beta-R1 in fibrosarcoma cells required transcription factors ISGF-3 and NF-kappa B. IFN-beta treatment did not augment the abundance of NF-kappa B, but led to phosphorylation of the NF-kappa B subunit p65 and induced a nuclear activity capable of phosphorylating a p65-GST fusion construct in the carboxy-terminal transactivation domain (TAD), residues 354-551.

Matrix metalloproteinase 9 (92-kDa gelatinase/type IV collagenase) from HT 1080 human fibrosarcoma cells. Purification and activation of the precursor and enzymic properties.
Transforming growth factor-beta1 induces tissue inhibitor of metalloproteinase-1 expression via activation of extracellular signal-regulated kinase and Sp1 in human fibrosarcoma cells.
PGI/AMF cellular expression in HT1080 human fibrosarcoma was down-regulated by small interfering RNA methodology, which resulted in an increased sensitivity to oxidative stress and oxidative stress-induced cellular senescence.

UCN-01 also exhibited significant antitumor activity against two murine tumor models (fibrosarcoma, K-BALB and M-MSV-BALB), which activated the v-ras and v-mos oncogenes, showing a minimum treated/control ratio of 0.27 (P less than 0.01) and 0.21 (P less than 0.01).
FMS-1 cells showed a fibrosarcoma-like or epithelioid pattern in the heterotransplanted tumor, compared with a fascicular growth pattern of short-spindle tumor cells in the primary tumor.
