Project description:This clinical trial studies the side effects of 18F-alphavbeta6-binding-peptide and how well it works in imaging patients with primary or cancer that has spread to the breast, colorectal, lung, or pancreatic. Radiotracers, such as 18F-alphavbeta6-binding-peptide, may improve the ability to locate cancer in the body.

Project description:Mitochondria are known to be functional organelles, but their role as a signaling unit is increasingly being appreciated. The recent identification of a short open reading frame (sORF) in the mitochondrial DNA (mtDNA) that encodes a signaling peptide, humanin, suggests the possible existence of additional sORFs in the mtDNA that yield bioactive peptides. Here we report the identification of a sORF within the mitochondrial 12S rRNA encoding a 16-amino-acid peptide named MOTS-c (mitochondrial open-reading-frame of the twelve S rRNA -c) that regulates insulin sensitivity and metabolic homeostasis. MOTS-c is detected in various tissues and in circulation in an age-dependent manner. Its primary target organ appears to be the skeletal muscle and its cellular actions inhibit the folate cycle and its tethered de novo purine biosynthesis, causing a significant accumulation of AICAR levels concomitantly with AMPK activation. MOTS-c treatment in mice prevented age-dependent and high-fat diet-induced insulin resistance, as well as diet-induced obesity. These results suggest that mitochondria may be more actively engaged in regulating metabolic homeostasis than previously recognized, through the production of peptides encoded within its genome that act at the cellular and organismal level. Human embryonic kidney cells (HEK293 cell line) were cultured in 10-cm dishes in 7 mL of phenol-free DMEM supplemented with 10% FBS and incubated with water (controls) or the 16-amino-acid peptide mitochondrial open-reading-frame of the twelve S rRNA-c (MOTS-c, 10 uM) for 4 or 72 hours prior to RNA extraction.

Project description:The aim of the study was to determine the epitope targeted by 5 different HumAbs and the cross-reactivity to linear peptide epitopes of 12 different factor H binding protein (fHbp) variants. The HumAbs were diluted at 1:200 and incubated on a custom PepStar Peptide Microarray platform printed with 363 different peptides.

Project description:We applied the high-throughput interaction assay SORTCERY to measure thousands of protein-peptide binding affinities and used the data to parameterize models of the peptide-binding landscape for three members of the Bcl-2 family of proteins. We applied the models to design peptides that bound with high affinity and specificity to just one of Bcl-xL, Mcl-1, or Bfl-1. We designed additional peptides that bound selectively to two out of three of these proteins. The raw data provided are the multiplexed fastq files that serve as inputs to our analysis pipeline. Additional detail is available in our corresponding publication and at the following github repository. https://github.com/KeatingLab/sortcery_design

Project description:DNA-binding transcription factors (TFs) have been challenging to target with molecular probes. Many TFs function in part through interaction with Mediator; we sought to block p53 function by disrupting the p53-Mediator interaction. Through rational design and activity-based screening, we characterized a stapled peptide, with functional mimics of both p53 activation domains, that selectively disrupted p53- and Mediator-dependent transcription in vitro. This “bivalent peptide” also suppressed p53 transcriptional response in human cancer cells. Our strategy circumvents the TF and instead targets the TF-Mediator interface, with desired transcriptional outcomes. Different TFs target Mediator through different subunits, suggesting this strategy could be generalizable.
