Nutrient/TOR signaling controls adipose mitochondrial transcription factor A (TFAM) to regulate organismal growth in Drosophila

FEBS Letters, EarlyView.
Animals must match their growth rate to available nutrients. We show that in Drosophila larvae, the nutrient‐sensing TOR kinase controls growth by regulating levels of TFAM, a key regulator of mitochondrial function, in the adipose tissue. When nutrients are abundant, high TOR activity suppresses TFAM, lowering mitochondrial bioenergetic activity and ...

Chemoselective Peptide Cyclization and Bicyclization Directly on Unprotected Peptides

, 2019
Cyclic peptides are drawing wide attention as potential medium-sized modulators of biomolecular interactions with large binding surfaces. Simple but effective peptide cyclization methods are needed to construct cyclic peptide libraries by both peptide ...

Supramolecular switching of the self-assembly of cyclic peptide–polymer conjugates via host–guest chemistry [PDF]

, 2019
A supramolecular strategy of switching the self-assembly of cyclic peptide–polymer conjugates using host–guest chemistry is proposed. The formation of tubular supramolecular polymers based on cyclic peptide–polymer conjugates can be controlled by ...

Engineering peptides into antibodies—opportunities and strategies for therapeutic innovation

FEBS Letters, EarlyView.
Peptides and antibodies occupy complementary therapeutic niches. Peptides recognize difficult targets in a compact format, while antibodies add specificity, long half‐life, and effector functions. This review examines strategies that merge both modalities—peptide grafting into loops, terminal and Fc fusions, and bioconjugation—highlighting how ...

Isocyanide-based multicomponent reactions towards cyclic constrained peptidomimetics

Beilstein Journal of Organic Chemistry, 2014
In the recent past, the design and synthesis of peptide mimics (peptidomimetics) has received much attention. This because they have shown in many cases enhanced pharmacological properties over their natural peptide analogues.

Cyclic Peptide-Based Sirtuin Substrates

Molecules, 2019
In the current study, four side chain-to-side chain cyclic peptides (three 5-mers and one 4-mer) harboring Nε-acetyl-lysine or Nε-myristoyl-lysine were found to be in vitro substrates of the human SIRT1/2/3-catalyzed deacylation with good ...

The microbiome in human skin aging

FEBS Letters, EarlyView.
Age‐related skin changes encompass the well‐known visible phenotypic alterations, together with microbiome dysbiosis and a series of molecular aging hallmarks. These hallmarks characterize not only a fully stablished aged phenotype but also the skin aging process itself.
