Porcine epidemic diarrhea virus (PEDV) is a member of the genera that has been associated with acute watery diarrhea and vomiting in swine. Unfortunately, no effective vaccines and antiviral drugs for PEDV are currently available. Reverse genetics systems are crucial tools for these researches. Here, a PEDV full-length cDNA clone was constructed. Furtherly, three PEDV reporter virus plasmids containing red fluorescent protein (RFP), Nano luciferase (Nluc), or green fluorescence protein (GFP) were generated using Red recombination with the GS1783 strain. These reporter-expressing recombinant (r) PEDVs showed similar growth properties to the rPEDV, and the foreign genes were stable to culture up to P9 in Vero cells. Using the Nluc-expressing rPEDV, the replication of PEDV was easily quantified, and a platform for rapid anti-PEDV drug screening was constructed. Among the three drugs, Bergenin, Umifenovir hydrochloride (Arbidol), and triterpenoids (GLTs), we found that GLTs inhibited PEDV replication mainly after the stage of virus "Entry". Overall, this study will broaden insight into the method for manipulating the PEDV genome and provide a powerful tool for screening anti-PEDV agents.

Targeting DNA damage response (DDR) pathways represents one of the principal approaches in cancer therapy. However, defects in DDR mechanisms, exhibited by various tumors, can also promote tumor progression and resistance to therapy, negatively impacting patient survival. Therefore, identifying new molecules from natural extracts could provide a powerful source of novel compounds for cancer treatment strategies.

The unicellular red alga Cyanidioschyzon merolae is a eukaryotic photosynthetic model organism used for basic and applied cell biology studies. Its nuclear genome can be modified by homologous recombination with exogenously introduced DNA. The comparison of mutants with isogenic strains is critical for reliable genetic analyses; however, this has been impossible thus far.

The secretory capacity of Chinese hamster ovary (CHO) cells remains a fundamental bottleneck in the manufacturing of protein-based therapeutics. Unconventional biological drugs with complex structures and processing requirements are particularly problematic. Although engineered vector DNA elements can achieve rapid and high-level therapeutic protein production, a high metabolic and protein folding burden is imposed on the host cell.

Sargramostim, a recombinant human granulocyte-macrophage colony-stimulating factor (GM-CSF) inhalation therapy, was recently approved for pharmaceutical use in Japan and shows promise as a treatment for autoimmune pulmonary alveolar proteinosis (APAP). For APAP patients with severe respiratory failure due to advanced lung fibrosis, lung transplantation is also a treatment option; however, APAP may recur after the procedure. Here, we report a case of successful sargramostim inhalation therapy for post-transplant APAP relapse in a patient who underwent living lung transplantation owing to severe fibrosis.
