The ability to genetically encode noncanonical amino acids (ncAAs) has empowered proteins with improved or previously unknown properties. However, existing strategies in mammalian cells rely on the introduction of a blank codon incorporate ncAAs, which is inefficient and limits their widespread applications. In this study, we developed rare recoding strategy that takes advantage relative rarity TCG achieve highly selective efficient ncAA incorporation through systematic engineering big...

Abstract The Hippo pathway regulates cell proliferation, apoptosis, and stem self-renewal, its inactivation in animal models causes organ enlargement followed by tumorigenesis. deregulation occurs many human cancers, but the underlying mechanisms are not fully understood. Here, we report tyrosine phosphorylation of tumor suppressor LATS1 as a mechanism regulation adhesion. A kinase library screen identified Src to directly phosphorylate on multiple residues, causing attenuated Mob activator...

Abstract An orthogonal aminoacyl-tRNA synthetase/tRNA pair is a crucial prerequisite for site-specific incorporation of unnatural amino acids. Due to its high codon suppression efficiency and full orthogonality, the pyrrolysyl-tRNA synthetase/pyrrolysyl-tRNA currently ideal system genetic code expansion in both eukaryotes prokaryotes. There pressing need discover or engineer other fully translation systems. Here, through rational chimera design by transplanting key components from...

Aberrant expressions of biomolecules occur much earlier than tumor visualized size and morphology change, but their common measurement strategies such as biopsy suffer from invasive sampling process. In vivo imaging slight biomolecule expression difference is urgently needed for early cancer detection. Fluorescence rare earth nanoparticles (RENPs) in second near-infrared (NIR-II) region makes them appropriate tool imaging. However, the incapacity to couple with signal amplification...

Site-specific incorporation of unnatural amino acids (UAAs) with similar efficiency to that natural (NAAs) and low background activity is extremely valuable for efficient synthesis proteins diverse new chemical functions design various synthetic auxotrophs. However, such translation systems remain largely unknown in the literature. Here, we describe engineered chimeric phenylalanine dramatically increase yield bearing UAAs, through systematic engineering aminoacyl-tRNA synthetase its...

Curcumin is a natural active product extracted from turmeric, has been reported to have anticancer properties against various tumors. However, the effect of curcumin on colon cancer remains still unclear. Our aimed investigate anti-colon in vitro, and determine molecular mechanisms underlying these effects. Viability assays including CCK8 LDH were used measure cell proliferation. Flow cytometry was performed detect apoptosis cycle distribution. qRT-PCR Western blotting for measuring...

Cation-π interactions are the major noncovalent for molecular recognition and play a central role in broad area of chemistry biology. Despite tremendous success understanding origin biological importance cation-π interactions, design synthesis stronger remain elusive. Here, we report an approach that greatly increases binding energy by replacing Trp aromatic box with electron-rich derivative using genetic code expansion strategy. The affinity between histone H3K4me3 its reader is increased...

Abstract The optical nanoprobes with emissions in the second near‐infrared window (NIR‐II, 1000–1700 nm) show low tissue autofluorescence and photon scattering; therefore, they provide high spatial resolution acceptable penetration depth. These advantages make them appropriate for vivo applications, including bioimaging, NIR‐II triggered disease therapy, even on‐site efficacy monitoring. Among various developed fluorescence probes, lanthanide‐doped nanoparticles (LDNPs) exhibit photo...

Despite tremendous success in understanding the chemical nature and importance of cation−π interactions a range biological processes, particularly epigenetic regulation, design synthesis stronger living cells remain largely elusive. Here, we several electron-rich Trp derivatives incorporate them into histone methylation reader domains to enhance affinity for marks via cells. We show that this site-specific replacement strategy is generally applicable engineering high-affinity major H3...
