Abstract: Recombinant protein coronavirus antigens and vaccine compositions using the same, include a recombinant protein that is a single-chain (SC) viral membrane protein complex derived from the spike (S), envelop (E) and membrane (M) protein of a coronaviruses such as SARS-CoV-2, the causal agent for COVID-19. Methods for immunization of a subject using the vaccine compositions treats or prevents clinical signs caused by coronaviruses infection.

Abstract: The disclosure provides 2-amino 4-nitrophenol and 2,4-diaminophenol derivatives, which can be used as anti-inflammatory drugs, prostaglandin E2 (PGE2) synthesis and activity inhibitors, and microsomal PGE2 synthase-1 (mPGES-1) inhibitors.

Abstract: The present disclosure provides use of non-steroidal anti-inflammatory compositions as described herein for used in the treatment of inflammation, inflammatory-related diseases, pain and/or fever.

Abstract: Described herein are single chain polypeptides comprising both the b- and a-chains of insulin fused to each other by a linker. Also provided are nucleic acids coding for the same, host cells expressing the same, and methods of use therefor.

Abstract: An effective amount of a composition comprising (i) a plasmid having a cyclooxygenase-prostacyclin synthase fusion gene, and (ii) a carrier fluid for use in treating an individual having a vascular disease or at risk of developing a vascular disease. A composition comprising a carrier fluid; and a DNA sequence encoding for a triple catalytic enzyme, a cDNA sequence encoding for a triple catalytic enzyme, a plasmid comprising a DNA sequence encoding for a triple catalytic enzyme, a fusion gene encoding for a triple catalytic enzyme, a cyclooxygenase-prostacyclin synthase fusion gene, or combinations thereof, for use in treating an individual having a vascular disease or at risk of developing a vascular disease.

Abstract: A recombinant 130-kDa protein is constructed by linking together human cyclooxygenase (COX) isoform-2 (COX-2) and prostacyclin synthase (PGIS), via a 10-20 amino acid residues of a transmembrane sequence. The engineered protein is expressed in cells, and adopts the functions of COX and PGIS, to continually convert arachidonic acid (AA) into prostaglandin G2 (catalytic step 1), prostaglandin H2 (catalytic step 2) and prostacyclin (PGI2; catalytic step 3).

Abstract: Provided herein are methods for producing a biomolecule by converting or engineering a plurality of cells, e.g., mammalian cells, having an endogenous precursor of a biomolecule to cells transfected to contain a nucleic acid that stably overexpresses a hybrid enzyme effective to metabolized the precursor to the biomolecule in the cell, e.g., prostacyclin produced from arachidonic acid. Also provided are methods of treating a pathophysiological condition associated with at least a decrease in the biomolecule or treating a vascular disease by administering the engineered, stably transfected mammalian cells to a subject where production of the biomolecule treats the condition or vascular disease. Further provided are the recombinant hybrid enzymes and the engineered cell lines and pharmaceutical compositions thereof, the nucleic acids encoding the hybrid enzymes, and vectors comprising the nucleic acids.
