We compared different expression strategies for STARD3, including the use of pelB and TorA signal peptides for potential periplasmic localization, and evaluated different E. coli strains to maximize cholesterol biotransformation. Although both signal peptides failed to efficiently transport STARD3 to the periplasm, with most of the protein remaining in the cytoplasm and membrane fractions, the STARD3 protein retained functionality in cholesterol transport. Auto-induction with lactose proved superior to IPTG-based induction, resulting in significantly higher expression levels of both STARD3 and P450scc. Among the E. coli strains tested (BL21(DE3), BL21(DE3)pLysS, HMS174(DE3), C41(DE3), and Rosetta(DE3)pLysS), Rosetta(DE3)pLysS demonstrated the highest STARD3 expression and the most significant impact of STARD3 on cholesterol biotransformation.

Research indicates that amyloid precursor protein (APP) might be a diagnostic marker and therapeutic target for HCC. However, the specific role of O-glycosylation of APP in NASH-HCC remains unclear. A NASH-HCC mice model was established by feeding BALB/c inbred mice with a high-fat/high-cholesterol (HFHC) diet and injection of CCl<sub>4</sub>. Hematoxylin-Eosin (HE) and Oil Red O (ORO) staining of liver tissue were then carried out to evaluate the progression of NASH-HCC. Immunohistochemistry (IHC) and Western blot were utilized to analyze APP levels. Immunoprecipitation (IP) was used to analyze the O-GalNAc modification of APP, and co-immunoprecipitation (Co-IP) and immunofluorescence were used to assess the Polypeptide N-Acetylgalactosaminyltransferase 18 (GALNT18) binding level of APP. Moreover, cell experiments confirmed the functional role of APP in HCC. APP was studied in vivo using an animal model. An up-regulation of APP and its O-glycosylation modification in patient-derived NASH-HCC tissues, animal models, and HCC cell lines was observed. The typical malignant phenotype of HCC, such as proliferation, migration, and invasion, was significantly suppressed by the knockdown of APP and was then partially rescued by the addition of UDP-GalNAc, a glycosylation activator. We demonstrated that GALNT18 interacted with APP in NASH-HCC models and upregulated its O-glycosylation. APP was finally shown to activate the EGR1/TGF-β1/Smad signaling, thereby driving the oncogenic progression of HCC. In vitro, APP knockdown inhibited NASH-HCC progression.

This study primarily aims to optimize recombinant HBsAg production in Pichia pastoris and evaluate its immunological comparability to the commercial HBV vaccine, thereby assessing its potential as a locally produced vaccine candidate. To achieve this, an eight-copy tandem construct of the HBsAg gene was created on the pPICZαA plasmid through an in vitro multimerization, and the production process of recombinant HBsAg was optimized. The presence of HBsAg in the supernatants following induction was confirmed, and the antigen was purified using various physical and biochemical methods. The highest yield of recombinant HBsAg was achieved with the eight-copy construct, following induction with 1% methanol and harvesting at 120 h, which was identified as the most productive time point. The antigenic properties of the produced HBsAg were compared with those of the commercially available vaccine, Engerix B™. Immunological testing using serum from anti-HBsAg positive individuals and immunized animals demonstrated that the recombinant rHBsAg exhibited similar antigenic characteristics to the commercial vaccine.
