3、Screening a novel FGF3 antagonist peptide with anti-tumor effects on breast cancer from a phage display library

摘要:Accumulating evidence has suggested that fibroblast growth factor??3 (FGF3) is expressed in breast cancer and correlates with the stage and grade of the disease. In the present study, a specific FGF3???binding peptide (VLWLKNR, termed FP16) was isolated from a phage display heptapeptide library with FGF3. The peptide FP16 contained four identical (WLKN) amino acids and demonstrated high homology to the peptides of the 188???194 (TMRWLKN) site of the high???affinity FGF3 receptor fibroblast growth factor receptor??2. Functional analyses indicated that FP16 mediated significant inhibition of FGF3???induced cell proliferation, arrested the cell cycle at the G0/G1 phase by increasing proliferation???associated protein??2G4, suppressing cyclin??D1 and proliferating cell nuclear antigen, and inhibited the FGF3???induced activation of extracellular signal???regulated kinase??1/2 and Akt kinase. Taken together, these results demonstrated that the peptide FP16, acting as an FGF3 antagonist, is a promising therapeutic agent for the treatment of breast cancer.

4、Trim9 Regulates Activity-Dependent Fine-Scale Topography in Drosophila

摘要:Topographic projection of afferent terminals into 2D maps in the CNS is a general strategy used by the nervous system to encode the locations of sensory stimuli. In vertebrates, it is known that although guidance cues are critical for establishing a coarse topographic map, neural activity directs fine-scale topography between adjacent afferent terminals [1-4]. However, the molecular mechanism underlying activity-dependent regulation of fine-scale topography is poorly understood. Molecular analysis of the spatial relationship between adjacent afferent terminals requires reliable localization of the presynaptic terminals of single neurons as well as genetic manipulations with single-cell resolution in vivo. Although both requirements can potentially be met in Drosophila melanogaster [5, 6], no activity-dependent topographic system has been identified in flies [7]. Here we report a topographic system that is shaped by neuronal activity in Drosophila. With this system, we found that topographic separation of the presynaptic terminals of adjacent nociceptive neurons requires different levels of Trim9, an evolutionarily conserved signaling molecule [8-11]. Neural activity regulates Trim9 protein levels to direct fine-scale topography of sensory afferents. This study offers both a novel mechanism by which neural activity directs fine-scale topography of axon terminals and a new system to study this process at single-neuron resolution.• Nociceptive afferents in Drosophila larva form fine-scale topography • Neural activity regulates larval nociceptive topography • Trim9 directs the fine-scale topography of larval nociceptive afferents • Neural activity regulates Trim9 expression to direct fine-scale topographyThe segregation of presynaptic terminals of same-type neurons is important for topographic projections of sensory afferents. Yang et al. report that nociceptive afferents in Drosophila larva form fine-scale topography. In this system, neural activity regulates Trim9 protein levels to direct fine-scale topography.
