Red-shifted click beetle luciferase mutant expands the multicolor bioluminescent palette for deep tissue imaging

open access: yesiScience, 2021
Summary: For in vivo multicolor bioluminescence applications, red and near-infrared signals are desirable over shorter wavelength signals because they are not as susceptible to light attenuation by blood and tissue. Herein, we describe the development of

Macromolecular assembly of bioluminescent protein nanoparticles for enhanced imaging

open access: yesMaterials Today Bio, 2022
Bioluminescence imaging has advantages over fluorescence imaging, such as minimal photobleaching and autofluorescence, and greater signal-to-noise ratios in many complex environments.

Luciferase Controlled Protein Interactions

open access: yesJournal of the American Chemical Society, 2021
Protein trafficking and protein-protein interactions (PPI) are central to regulatory processes in cells. Induced dimerization systems have been developed to control PPI and regulate protein trafficking (localization) or interactions. Chemically induced dimerization (CID) has proven to be a robust approach to control protein interactions and ...

An epithelial GPR35 isoform supports tumor‐associated transcriptional and metabolic phenotypes

open access: yesFEBS Letters, EarlyView.
GPR35 generates two functionally distinct isoforms with previously unresolved roles. GPR35‐short mediates immune‐cell chemotaxis, while GPR35‐long is enriched in colorectal cancer epithelium, where it supports increased metabolism, proliferation, and tumor‐associated transcriptional programs.

Codon-Optimized Luciferase Variants for Mammalian Gene Expression in Culture and in Vivo

open access: yesMolecular Imaging, 2012
Luciferases have proven to be useful tools in advancing our understanding of biologic processes. Having a multitude of bioluminescent reporters with different properties is highly desirable.

Gaussia Luciferase for Bioluminescence Tumor Monitoring in Comparison with Firefly Luciferase [PDF]

open access: yesMolecular Imaging, 2011
Gaussia luciferase (Gluc) is a secreted reporter, and its expression in living animals can be assessed by in vivo bioluminescence imaging (BLI) or blood assays. We characterized Gluc as an in vivo reporter in comparison with firefly luciferase (Fluc). Mice were inoculated subcutaneously with tumor cells expressing both Fluc and Gluc and underwent Flue ...

Engineered extracellular vesicles enriched with the miR‐214/199a cluster enhance the efficacy of chemotherapy in ovarian cancer

open access: yesMolecular Oncology, EarlyView.
Loss of the miR‐214/199a cluster is associated with recurrence in ovarian cancer. Engineered small extracellular vesicles (m214‐sEVs) elevate miR‐214‐3p/miR‐199a‐5p in tumor cells, suppress β‐catenin, TLR4, and YKT6 signaling, reprogram tumor‐derived sEV cargo, reduce chemoresistance and migration, and enhance carboplatin efficacy and survival in ...

Establishment of a humanized patient‐derived xenograft mouse model of high‐grade serous ovarian cancer for preclinical evaluation of combination immunotherapy

open access: yesMolecular Oncology, EarlyView.
We have established a humanized orthotopic patient‐derived xenograft (Hu‐oPDX) mouse model of high‐grade serous ovarian cancer (HGSOC) that recapitulates human tumor–immune interactions. Using combined anti‐PD‐L1/anti‐CD73 immunotherapy, we demonstrate the model's improved biological relevance and enhanced translational value for preclinical ...

Thermostability of Firefly Luciferases Affects Efficiency of Detection by in Vivo Bioluminescence

open access: yesMolecular Imaging, 2004
Luciferase from the North American firefly ( Photinis pyralis ) is a useful reporter gene in vivo, allowing noninvasive imaging of tumor growth, metastasis, gene transfer, drug treatment, and gene expression.

Oncogenic DMTF1β promotes cancer cell motility by regulating autophagy through ULK1 stabilization

open access: yesMolecular Oncology, EarlyView.
In the current study, we demonstrate that the oncogene DMTF1β regulates ULK1 stability by reducing its proteasomal degradation in cancer cells. This stabilization enables ULK1 to induce autophagy, which in turn facilitates cancer cell migration. Consequently, reduced DMTF1β levels lead to decreased autophagy and impaired cancer cell migration.
