NOVEL ACYLTRANSFERASES, VARIANT THIOESTERASES, AND USES THEREOF
Disclosed are microalgal cells having an ablated or downregulated fatty acyl-ACP thioesterase (FATA) gene, wherein the cell is modified to express a heterologous lysophosphatidic acid acyltransferase (LPAAT) comprising an amino acid sequence that has at least 80% identity to an acyltransferase encoded by SEQ ID NO: 90, 89, 92, 93 or 95 and wherein the modified microalgal cell produces an oil with an elevated ratio of saturated-unsaturated-saturated triglycerides over trisaturated triglycerides as compared to a corresponding unmodified cell. Also disclosed are microalgal oils comprising at least 60% stearate-oleate-stearate (SOS) triglycerides, less than 5% trisaturates and wherein the fatty acid profile of the oil comprises at least 50% C18:0. Related methods of producing an oil are also disclosed.
Modulators of PNPLA3 expression
The present embodiments provide methods, compounds, and compositions useful for inhibiting PNPLA3 expression, which may be useful for treating, preventing, or ameliorating a disease associated with PNPLA3.
Increasing lipid production and optimizing lipid composition
Disclosed are nucleotide sequences and corresponding amino acid sequences of Arxula adeninivorans genes that can be utilized to manipulate the lipid content and/or composition of a cell. Methods and compositions for utilizing this information are disclosed to increase the lipid content or modify the lipid composition of a cell by either increasing or decreasing the activity of certain genetic targets.
MODULATORS OF PNPLA3 EXPRESSION
The present embodiments provide methods, compounds, and compositions useful for inhibiting PNPLA3 expression, which may be useful for treating, preventing, or ameliorating a disease associated with PNPLA3.
STRUCTURING FATS AND METHODS OF PRODUCING STRUCTURING FATS
Recombinant DNA techniques are used to produce oleaginous recombinant cells that produce triglyceride oils having desired fatty acid profiles and regiospecific or stereospecific profiles. Genes manipulated include those encoding stearoyl-ACP desaturase, delta 12 fatty acid desaturase, acyl-ACP thioesterase, ketoacyl-ACP synthase, and lysophosphatidic acid acyltransferase. The oil produced can have enhanced oxidative or thermal stability, or can be useful as a frying oil, shortening, roll-in shortening, tempering fat, cocoa butter replacement, as a lubricant, or as a feedstock for various chemical processes. The fatty acid profile can be enriched in midchain profiles or the oil can be enriched in triglycerides of the saturated-unsaturated-saturated type.
NOVEL ACYLTRANSFERASES AND METHODS OF USING
Provided herein are novel acyltransferases and methods of using such novel acyltransferases in making medium-chain fatty acids.
SACCHAROMYCES CEREVISIAE STRAIN FOR PRODUCING HUMAN MILK LIPID SUBSTITUTE AND USE THEREOF
The invention provides a Saccharomyces cerevisiae strain for producing a human milk lipid substitute. By integrating a heterologous lysophosphatidic acid acyltransferase into Saccharomyces cerevisiae and knocking out its own natural lysophosphatidic acid acyltransferase, the content of palmitic acid (C16:0) at Sn-2 position of triacylglycerol produced by Saccharomyces cerevisiae is increased, to synthesize a human milk lipid substitute. On this basis, a metabolic pathway related gene is knocked out, to further increase the content of human milk lipid substitute in the product. In the present invention, a human milk lipid substitute is de novo synthesized by Saccharomyces cerevisiae for the first time, in which the total fatty acid is 15% or more, and the relative content of C16:0 at Sn-2 position reaches about 60%.
FUNGAL CELLS FOR TAILORED FATS
The present invention generally related to a fungal cell capable of tailored triacylglycerols. The fungal cell comprises at least one modification to the endogenous fatty acid metabolism.
USE OF MULTIGENE STACKING METHOD IN SYNTHESIS OF NERVONIC ACID IN BRASSICA NAPUS
The present disclosure relates to use of a multigene stacking method in synthesis of nervonic acid in Brassica napus. The present disclosure provides a multigene co-expression plant vector, including an initial backbone of pBWA(V)BII and multiple exogenous gene expression cassettes. The present disclosure further provides two plant vectors applicable to genetic transformation, including a three-gene co-expression plant vector and a five-gene co-expression plant vector. In the present disclosure, after the three-gene co-expression plant vector and the five-gene co-expression plant vector are separately transferred into the Brassica napus, the nervonic acid (NA) with a high content is synthesized in the Brassica napus through multigene co-expression. An NA ratio can be significantly increased combined with a higher seed oil content and a greater field seed yield. The plant vector realizes efficient synthesis of NA in oil crops, obtains NA-rich seed oil, and increases an added value of edible oil.
Modulation of AGPAT5 expression
Provided herein are methods, compounds, and compositions for reducing expression of an AGPAT5 mRNA and protein in an animal. Also provided herein are methods, compounds, and compositions for reducing lipids, insulin resistance and/or glucose in an animal. Such methods, compounds, and compositions are useful to treat, prevent, delay, or ameliorate a cardiometabolic disease, disorder or condition, or a physiological marker thereof, in an individual in need.
