Abstract Plant chloroplasts have a highly compartmentalized interior, essential for executing photocatalytic functions. However, the construction of reaction compartment similar to in inorganic–biological hybrid systems (IBS) has not been reported. Drawing inspiration from chloroplast and phenomenon liquid–liquid phase separation, herein, new strategy is first developed constructing subcellular system through separation technology living cells. Photosensitizers vivo expressed hydrogenases...

Molecule encapsulation in virus-based nanoparticles (VNPs) is an emerging bioinspired way to design novel functional nanostructures and devices. Here, we report a general cargo-compatible approach encapsulate guest materials based on the apparent critical assembly concentration (CACapp) of VNPs. Different from conventional buffer-exchange method, new method drives reassembly VNPs cargoes by simply concentrating adequately diluted mixture VNP building blocks above CACapp. This has been proved...

Lung adenocarcinoma is a malignant and fatal respiratory disease. However, due to its complex pathogenesis poorly effective therapeutic options, accurate early diagnosis prognosis remain elusive. Now, there increasing evidence that tumor stem cells are involved in tumorigenesis, metastasis, relapse, resistance chemotherapy radiotherapy one of the reasons why tumors cannot be cured. The mRNA expression based-stemness index (mRNAsi) parameter obtained by Malta his colleagues applying...

Crystals in Bacillus thuringiensis are usually formed the mother cell compartment during sporulation and separated from spores after lysis. In a few strains, crystals produced inside exosporium associated with sporulation. This special phenotype, named 'spore crystal association' (SCA), typically occurs B. subsp. finitimus. Our aim was to identify genes determining SCA phenotype finitimus strain YBT-020. Plasmid conjugation experiments indicated that this tightly linked two large plasmids...

Abstract Self‐assembled virus‐like particles (VLPs) hold great potential as natural nanomaterials for applications in many fields. For such purposes, monodisperse size distribution is a desirable property. However, the VLPs of simian virus 40 (SV40), representative VLP platform, are characterized by polymorphism. In an attempt to eliminate polymorphism, 15 mutants subunit (VP1) constructed through substitution double cysteines at VP1 pentamer interfaces, generating group with altered...

HBV-associated hepatitis B virus x protein (HBx) plays multiple roles in the development of hepatocellular carcinoma. In our prior study, we discovered that miR-187-5p expression was inhibited by HBx. To investigate underlying molecular mechanism HBx-mediated downregulation carcinoma cells, effects HBx and on hepatoma cell were observed, as well their interactions. Through vitro vivo experiments, demonstrated overexpression proliferation, migration, invasion. Simultaneously, observed a...
