Ionizing Radiation-Induced RPL23a Reduction Regulates Apoptosis RPL11-MDM2-p53 Pathway in Mouse Spermatogonia.

Objective: The expression patterns of ribosomal large subunit protein 23a (RPL23a) in mouse testes and GC-1 cells were analyzed to investigate the potential relationship between RPL23a expression and spermatogonia apoptosis upon exposure to X-ray.

Methods: Male mice and GC-1 cells were irradiated with X-ray, terminal dUTP nick end-labelling (TUNEL) was performed to detect apoptotic spermatogonia . Apoptotic rate and cell cycle phase of GC-1 cells were analyzed with flow cytometry.

Comparative transcriptomics and histopathological analysis of crucian carp infection by atypical Aeromonas salmonicida.

Aeromonas salmonicida is a ubiquitous fish pathogen known to cause furunculosis. With the emergence of new subtypes and the expansion of the host range, it has threatened the health of a variety of marine and freshwater fish, particularly the non-salmonids, manifesting differently from the classical furunculosis. Although there have been reports of infection by atypical strains on the crucian carp, the pathogenesis and tissue pathology remain unclear.

A recombinant adenovirus targeting typical Aeromonas salmonicida induces an antibody-mediated adaptive immune response after immunization of rainbow trout.

Aeromonas salmonicida, the oldest known fish pathogen and currently endemic throughout most of the world in both fresh and marine waters, causes severe economic losses to the salmon farming industry. Although there have been many studies on the prevention of furunculosis over the past few decades, it is still prevalent in many fisheries. In this study, a recombinant adenovirus vaccine candidate harboring the highly immunogenic Vapa gene (pAd-easy-cmv-Vapa) was successfully constructed and tested.

Effects of Bombyx mori nuclear polyhedrosis virus on serpin and antibacterial peptide expression in B. mori.

The silkworm (Bombyx mori) is a typical and economically important lepidopteran species, and research has resulted in the development and accumulation of breeding lines. Studies of immune-related silkworm genes not only promote our understanding of silkworm immune response mechanisms, but they also inform insect immune molecular diversity research. Here, silkworm proteins were screened using proteomics after Bombyx mori nuclear polyhedrosis virus (BmNPV) infection, and 2368 silkworm proteins were identified, including six antimicrobial peptides and 12 serpins.

Baculoviral infection reduces the expression of four allergen proteins of silkworm pupa.

Silkworm (Bombyx mori) larvae are widely used to express exogenous proteins. Moreover, some silkworm pupal proteins can be used as drug-loading materials for selfexpressed oral tolerance drugs. However, several proteins expressed in silkworm pupae cause severe allergic reactions in humans and animals.

iTRAQ proteomic analysis of the interactions between Bombyx mori nuclear polyhedrosis virus and silkworm.

Unlabelled: The silkworm hemolymph is an important defense system against bacteria and viruses. In this study, silkworms were infected with Bombyx mori nuclear polyhedrosis virus to investigate the subsequent immune response at the protein level. Proteomes were analyzed before and after infection using isobaric tags for relative and absolute quantitation and LC-MS.
