The nucleotide and amino acid sequences of indoleamine 2,3-dioxygenase-2 (IDO2) and methods of use thereof are provided.

A natural peptide comprising a cellular growth promoting fragment of a protein selected from SEQ ID NO’s: 1 to 13, and a composition comprising a plurality of growth promoting peptides, is described. Also disclosed is the use of the peptides and compositions in prevention of ageing of human skin, treatment of diseases or conditions characterised by damaged epithelial cells or tissue such as colon cancer and peripheral inflammatory disorders, and wound treatment. Specific pea and rice protein derived peptides are described in SEQ ID NO’s: 15 to 505, and 546 to 704.

Synthetic adenoviruses with tropism to bone tissue are described. The synthetic adenoviruses include an adenovirus type 11 (Ad11) fiber protein or a chimeric adenovirus fiber protein having an Ad11 knob domain. The synthetic adenoviruses can also include a transgene, such as a reporter gene or a transgene encoding a factor that promotes bone regeneration or repair. Use of the synthetic adenoviruses to target bone tissue and/or to promote bone repair or regeneration is also described.

The present invention relates to processes for the formation of pyridinedicarboxylic acid (PDCA), in particular, 2,4-pyridinedicarboxylic acid (2,4-PDCA) and 2,5-pyridinedicarboxylic acid (2,5-PDCA), and mono- and diester derivatives thereof, from 3,4-dihydroxybenzoic acid, via a biocatalytic reaction using, for example, a protocatechuate dioxygenase such as protocatechuate 4,5-dioxygenase or protocatechuate 2,3-dioxygenase, and a nitrogen source. The invention also relates to copolymers that comprise the pyridinedicarboxylic acid monomers and derivatives thereof, processes for the formation of the copolymers and uses for the copolymers.

Provided herein are methods and compositions for treating cancer, including cancer that is not responsive to immunotherapy. In one aspect, the methods of treatment comprise administering to the subject a therapeutically effective amount of a β-catenin inhibitor, a therapeutically effective amount of an IDO inhibitor, and a therapeutically effective amount of an immunotherapeutic agent. Another aspect is directed to pharmaceutical compositions comprising a β-catenin inhibitor for use in treating cancer, wherein the composition is administered in combination with an IDO inhibitor and an immunotherapeutic agent. Yet another aspect is directed to a method of potentiating the therapeutic effect of immunotherapy against a cancer using a β-catenin inhibitor, such as a β-catenin nucleic acid inhibitor molecule, in combination with an IDO inhibitor.

The present disclosure relates to a genetically modified microbial cell that includes a first genetic modification resulting in the expression of an exogenous vanillate demethylase, such that the microbial cell is capable of metabolizing an S-lignin decomposition product and producing 2-pyrone-4,6-dicarboxylate (PDC).

Described herein is a PAH-degrading enzyme mixture obtained from a culture of PAH-utilizing microorganisms having been grown in presence of one or more enzyme inducers. Related methods and devices are also described.

Improved formulations of lipid nanoparticles are provided. Use of the lipid nanoparticles for delivery of a therapeutic agent and methods for their preparation are also provided.

The present disclosure provides compositions and methods for detecting the presence of neutralizing antibodies in a sample. Unlike conventional assays, the methods provided herein do not require the use of live virus or virus pseudoparticles to identify neutralizing antibodies.
