    Mouse beta-interferon (at a concentration of 100 units/ml or higher) inhibited the platelet-derived growth factor (PDGF)-induced replication of quiescent BALB/c-3T3 cells. The interferon treatment did not inhibit, but slightly enhanced, the accumulation of the following three PDGF-induced RNAs: myc RNA, JE RNA, and KC RNA. The treatment with interferon changed the pattern of secreted proteins from quiescent cells and from cells treated with partially purified PDGF; it inhibited the accumulation of the PDGF-induced proteins (including proteins of 63 and 32 kDa) and it induced the accumulation of several other proteins (including proteins of 89, 31.5, 30, and 10.5 kDa) in both quiescent and also in PDGF-treated cells.

    TGF - β Signaling Pathway

    The TGF-β signaling pathway regulates cell growth, differentiation, adhesion, motility, and development. TGF-β ligands that induce TGF-β signaling are synthesized in their latent form. Several proteases or cell surface receptors such as integrins act upon the latent form, releasing the active ligand. There are three types of mammalian TGF-βs: (TGF-β1, TGF-β2, and TGF-β3) that bind as homodimers or heterodimers to TGF-β receptors. The TGF-β receptors are of three kinds RI, RII, and RIII. The RI...

    Inhibitors of Viral Protein Synthesis

    Protein synthesis is indispensable for viral replication, as viruses lack the cellular machinery required for this process and must hijack the host's translational apparatus. In response, host cells deploy a critical innate immune defense involving interferons, specialized cytokines that play a central role in inhibiting viral propagation.Upon viral detection, infected cells release interferons that bind to receptors on adjacent uninfected cells, activating the JAK-STAT signaling pathway and...
