摘要:
Methods and composition for a melatonin signaling modulator-based diagnosis and therapy are described. For example, in certain aspects methods for administering an anti-tumor therapy using a melatonin signaling modulator are described. Furthermore, the invention provides compositions and methods for detecting biliary tract disease such as cholangiocarcinoma.
摘要:
Novel isolated DNA sequences associated with the lignin biosynthetic pathway are provided, together with DNA constructs including such sequences. Methods for the modulation of lignin content in plants are also disclosed, the methods comprising incorporating one or more of the inventive DNA sequences or a sequence complementary to an inventive DNA sequence into the genome of a plant.
摘要:
Described herein are variants of acetylserotonin O-methyltransferase (ASMT) as well as vectors and recombinant microbial host cells expressing such ASMT variant and their use in producing melatonin and related compounds. Preferred ASMT variants provide for a higher turnover of N-acetylserotonin into melatonin.
摘要:
Recombinant microbial cells and methods for producing melatonin and related compounds using such cells are described. More specifically, the recombinant microbial cell may comprise exogenous genes encoding one or more of an L-tryptophan hydroxylase, a 5-hydroxy-L- tryptophan decarboxylyase, a serotonin acetyltransferase, an acetylserotonin O- methyltransferase; an L-tryptophan decarboxy-lyase, and a tryptamine-5-hydroxylase, and means for providing tetrahydrobiopterin (THB). Related sequences and vectors for use in preparing such recombinant microbial cells are also described.
摘要:
Recombinant microbial cells and methods for producing 5HTP, melatonin and related compounds using such cells are described. More specifically, the recombinant microbial cell may comprise exogenous genes encoding one or more of an L-tryptophan hydroxylase, a 5- hydroxy-L-tryptophan decarboxylyase, a serotonin acetyltransferase, an acetylserotonin O- methyltransferase; and means for providing tetrahydrobiopterin (THB), and can be further genetically modified to enrich one or more of tryptophan, S-adenosyl-L-methinonine and acetyl coenzyme A. Related sequences and vectors for use in preparing such recombinant microbial cells are also described.
