Aim: To construct the eukaryotic expression vector pEGFP-N1/ACRBP and stably express ACRBP in human hepatocarcinoma cells, providing functional clues for ACRBP.
Methods: A recombinant plasmid pMAL-C2/ACRBP was used as a template to amplify ACRBP cDNA. The PCR product was ligated into an eukaryotic expression vector pEGFP-N1 to construct a recombinant plasmid pEGFP-N1/ACRBP. Then the pEGFP-N1/ACRBP was transfected by Fugene HD into ACRBP-negative HepG2 cells. The stably transfected clones were selected by G418. RT-PCR and immunohistochemistry were used to detect the expression of ACRBP in HepG2 cells.
Results: The eukaryotic expression vector pEGFP-N1/ACRBP was constructed and confirmed by sequencing. The stably transfected HepG2 cells expressed ACRBP.
Conclusion: The eukaryotic expression vector pEGFP-N1/ACRBP has been successfully constructed and transfected into HepG2 cells, resulting in stable expression of ACRBP.

Globally, the prevalence of coronary artery disease (CAD) is increasing, accounting for a third of all deaths worldwide including myocardial infarctions (MIs) which represent the most severe clinical manifestation of CAD and are among the most dangerous coronary events. Therefore, this study aims to assess the knowledge of symptoms and risk factors of MIs, as well as attitudes and beliefs regarding MIs and confidence in recognizing CAD symptoms in Riyadh, Saudi Arabia. A cross-sectional study was conducted among individuals living in Riyadh, Saudi Arabia between November 2023 and April 2024 to assess their knowledge and beliefs about CAD and MIs.

Tilapia lake virus (TiLV) disease is highly contagious and causes substantial mortality in tilapia. Currently, no effective treatments or commercial vaccines are available to prevent TiLV infection. In this study, TiLV segment 4 (S4) was cloned into the pET28a(+)vector and transformed into Escherichia coli BL21(DE3).

The introduction of anti-PD-1/PD-L1 therapies revolutionized treatment for advanced non-small cell lung cancer (NSCLC), yet response rates remain modest, underscoring the need for predictive biomarkers. While a T cell inflamed gene expression profile (GEP) has predicted anti-PD-1 response in various cancers, it failed in a large NSCLC cohort from the Stand Up To Cancer-Mark (SU2C-MARK) Foundation. Re-analysis revealed that while the T cell inflamed GEP alone was not predictive, its performance improved significantly when combined with gene signatures of myeloid cell markers.

The cell painting assay is useful for understanding cellular phenotypic changes and drug effects. To identify other aspects of well-known chemicals, we screened 258 compounds with the cell painting assay and focused on a mitochondrial punctate phenotype seen with disulfiram. To elucidate the reason for this punctate phenotype, we looked for clues by examining staining steps and gene knockdown as well as examining protein solubility and comparing cell lines.
