Methods and immunoassays for the determination of fatty acid synthase (FAS) expression in patients having or suspected of having a proliferative disorder, especially prostate cancer, are disclosed. The sensitive method and assay detect the level of expression of FAS in a biological sample using antibodies that are highly specific for FAS. The method and assay can be used to monitor the progression of cancer, and / or to predict the efficacy of certain treatments or the likelihood of recurrence of the cancer.

The present invention is directed to isolated nucleic acid molecules and polypeptides of thraustochytrid polyunsaturated fatty acid (PUFA) synthases involved in the production of PUFAs, including PUFAs enriched in docosahexaenoic acid (DHA), eicosapentaenoic acid (EPA), or a combination thereof. The present invention is directed to vectors and host cells comprising the nucleic acid molecules, polypeptides encoded by the nucleic acid molecules, compositions comprising the nucleic acid molecules or polypeptides, and methods of making and uses thereof.

This invention describes the preparation of fatty acid esters of glycerol formal either by a triglyceride transesterification process or, alternatively, by an esterification process of fatty acids previously obtained from the hydrolysis of triglycerides (fat splitting), with glycerol formal in the presence of an acid or basic catalyst. Also the invention describes the use of these fatty acid esters of glycerol formal prepared by said process as biofuel. In an embodiment, such biofuel is used in the preparation of other biofuels by its mixture with a product selected from a group formed by: glycerol formal, biodiesel, petrol-derived diesel, and mixtures thereof. The biofuels thus obtained are characterized to allow the complete incorporation of the glycerol obtained in the current biodiesel production process in a biodiesel fuel.

The invention describes the preparation, isolation and use of an extract of kiwi fruit for the treatment of a disease or condition related with, caused by or mediated by activity of human pancreatic lipase and / or human fatty acid synthase.

Lipogenic yeasts bioengineered to overexpress genes for lipid production, and methods of use thereof. The yeasts are modified to express, constitutively express, or overexpress an acetyl-CoA carboxylase, an alpha-amylase, an ATP citrate lyase, a diacylglycerol acyltransferase, a fatty acid synthase, a glycerol kinase, a 6-phosphogluconate dehydrogenase, a glycerol-3-phosphate dehydrogenase, a malic enzyme, a fatty acyl-CoA reductase, a delta-9 acyl-CoA desaturase, a glycerol-3-phosphate acyltransferase, a lysophosphatidate acyltransferase, a glucose-6-phosphate dehydrogenase, a beta-glucosidase, a hexose transporter, a glycerol transporter, a glycoside hydrolase enzyme, an auxiliary activity family 9 enzyme, or combinations thereof. The yeasts in some cases are also modified to reduce or ablate activity of certain proteins. The methods include cultivating the yeast to convert low value soluble organic stillage byproducts into lipids suitable for biodiesel production and other higher value uses.
