The interferon-inducible nucleolar p204 protein binds the ribosomal RNA-specific UBF1 transcription factor and inhibits ribosomal RNA transcription.
p204, a member of the interferon-inducible p200 family of murine proteins, is primarily nucleolar. We generated cell lines in which p204 was inducible by muristerone. This induction resulted in retardation of cell proliferation and inhibition of rRNA transcription in vivo. Interferon treatment, resulting in p204 induction and retardation of proliferation, also caused inhibition of rRNA transcri...
متن کاملDecomposition of ribosomal particles in Escherichia coli treated with mitomycin C.
Exposure of cells of Escherichia coli to mitomycin C (5 mug/ml) resulted in a marked change in the sedimentation profiles of the cell-free extracts, indicating a specific decomposition of ribosomal particles. When the extracts were prepared in the presence of 0.01 m Mg(++) and analyzed by sucrose density gradient centrifugations, the 100S fraction disappeared rapidly from the treated cells. The...
متن کامل[Mitomycin C and excimer laser].
Mitomycin C is an antimetabolite agent that blocks DNA and RNA replication and protein synthesis. It has been used in several ophthalmologic areas, and recently as a modulator of corneal wound healing in excimer laser surgeries. A single application of mitomycin C during surface corneal photoablative surgery seems a safe and efficient therapeutic option for eyes with corneal opacity and/or as p...
متن کاملMitomycin-C Use in Ophthalmology
Mitomycin-C is a chemotherapeutic drug that acts by inhibiting DNA synthesis. Its use and application in ophthalmology has been increasing in recent years because of its mandatory effects on wound healing. Current applications include pterygium surgery, glaucoma surgery, corneal refractive surgery, cictracial eye disease, conjunctivalneoplasia, dacryocystorhinostomy surgeries and allergic eye d...
متن کاملMitomycin C in photorefractive keratectomy.
PURPOSE To evaluate the outcome of primary or retreatment photorefractive keratectomy (PRK) or phototherapeutic keratectomy (PTK) with mitomycin C (MMC) 0.02% applied prophylactically intraoperatively for the prevention of haze and regression in cases of significant haze and regression after primary PRK, due to previous radial keratotomy (RK), in primary PRK eyes with high myopia, and in comeas...
