The viral vector includes a small RNA optimized to target an FDPS mRNA sequence. The aminobisphosphonate drug includes zoledronic acid.

The present disclosure relates to the production of cannabinoids in yeast. In as aspect there is provided a genetically modified yeast comprising: one or more GPP producing genes and optionally, one or more GPP pathway genes; two or more olivetolic acid producing genes; one or more cannabinoid precursor or cannabinoid producing genes; one or more Hexanoyl-CoA producing genes, and at least 5% dry weight of fatty acids or fats.

A system and method is provided for producing linear and branched hydrocarbons and in particular triterpenes in plant cells. The system and method includes a transformed plant cell with an isolated nucleic acid encoding a farnesyl diphosphate synthase (FPS) and with an isolated nucleic acid encoding a triterpene synthase.

The present disclosure provides methods and compositions for producing rotundone. In various aspects, the present disclosure provides enzymes, polynucleotides encoding said enzymes, and recombinant microbial host cells (or microbial host strains) for the production of rotundone. In some embodiments, the present disclosure provides microbial host cells for producing rotundone at high purity and/or yield, from either enzymatic transformation of α-guaiene, or from sugar or other carbon source. The present disclosure further provides methods of making products containing rotundone, including flavor or fragrance products, among others.

The present invention relates to a recombinant Deinococcus bacterium exhibiting enhanced 2-C-methyl-D-erythritol 4-phosphate/1-deoxy-D-xylulose 5-phosphate (MEP/DXP) pathway, and its use for producing terpene or terpenoid compounds.

A method for producing γδ T cells modified by a chimeric antigen receptor, comprising: transfecting K562 cells with shFPPS targeted to FPP synthase by means of a lentiviral vector, such that the expression of FPPS in the K562 cells is lowered and a K562-shFPPS cell line with reduced FPPS expression is constructed; adding the K562-shFPPS cell line into a γδ T cell culture system for co-culturing with the γδ T cells, wherein it is found that the K562-shFPPS cell line can facilitate in vitro differentiation and proliferation of the γδ T cells; and adding a CAR-expressing lentiviral vector to the γδ T cell culture system comprising the cell line for co-culturing, wherein it is found that the K562-shFPPS cell line can further effectively improve the transfection rate of CAR genes. The provided solution effectively overcomes the technical challenge of the large-scale production of CAR-γδ T cells, and has a good application prospect.
