The Hedgehog (Hh) signaling pathway plays an important role in embryonic patterning and development of many tissues organs as well maintaining repairing mature adults. Uncontrolled activation the Hh-Gli has been implicated developmental abnormalities several cancers, including brain tumors like medulloblastoma glioblastoma. Inhibition aberrant has, thus, emerged attractive approach for anticancer therapy; however, mechanisms that mediate vertebrates remain poorly understood. Here, we show...

Protein-based microarrays are among the novel class of rapidly emerging proteomic technologies that will allow us to efficiently perform global proteome analysis. However, process designing adequate protein is a major inherent problem. In this study, we have evaluated microarray platform based on nonpurified affinity-tagged single-chain (sc) Fv antibody fragments generate proof-of-principle and demonstrate specificity sensitivity array design. To end, used our human recombinant scFv library...

High-throughput proteomics, based on the microarray platform, requires stable, highly functional components that will yield a sensitive read-out of low abundance proteins. Although antibodies are best characterized binding molecules for this purpose, only fraction them appear to behave satisfactorily in chip format. Therefore, high demands need be placed their molecular design. In present study, we have focused recombinant antibody design single framework protein applications, aiming at...

Antibody-based microarray is a novel technology with great promise in biomedicine that will provide unique means to perform global proteome analysis. In the process of designing high-density antibody microarrays required, several critical key issues have been identified remain be resolved. particular, there need for specific and selective approaches enabling non-purified probes directly purified, orientated coupled generic one-step procedure on chip. this study, we report successful design...

In eukaryotic cells an uncleavable ubiquitin moiety conjugated to the N-terminus of a protein signals degradation fusion via proteasome-dependent (UFD) pathway. yeast molecular mechanism UFD pathway has been well characterized. Recently human E3 ubiquitin-protein ligase TRIP12 was connected with pathway, but little is otherwise known about this system in mammalian cells. present work, we utilized high-throughput imaging on transfected targeted siRNA library identify components involved...

Oncogene-induced senescence (OIS) can occur in response to hyperactive oncogenic signals and is believed be a fail-safe mechanism protecting against tumorigenesis. To identify new factors involved OIS, we performed screen for microRNAs that overcome or inhibit OIS human diploid fibroblasts. This led the identification of miR-378a-5p addition several other miRNAs have previously been shown play role senescence. We show ectopic expression reduces markers, including p16INK4A...

During the metastatic process, breast cancer cells must come into contact with extra-cellular matrix (ECM) at every step. The ECM provides both structural support and biochemical cues, cell–ECM interactions can lead to changes in drug response. Here, we used fibroblast-derived (FDM) perform high throughput screening of 4T1 on organ (lung), see that response differs from treatment plastic. FDMs produce different organs are abundant contains a complex mixture proteins. We also show differences...

Abstract The histone demethylase PHF8 catalyzes demethylation of mono‐ and di‐methylated Lys9 on H3 (H3K9me1/2), is a transcriptional activator involved in the development cancer. Affinity specificity towards H3K9me2 affected by interaction with both catalytic domain PHD reader domain. latter specifically recognizes tri‐methylated Ly4 H3. A fragment tail Lys4 was used as template for structure‐based design cyclic, cell‐penetrating peptide that exhibits micromolar binding affinity to...

Uncontrolled activation the Hh-Gli has been implicated developmental abnormalities several cancers, including brain tumors like medulloblastoma glioblastoma. Inhibition aberrant thus emerged attractive target for anticancer therapy, however mechanisms that mediate vertebrates remain still poorly understood. Here, we...
