Antitumor activities of extracts and compounds from water decoctions of Taxus cuspidata.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Water decoctions from the leaves of Taxus cuspidata are used in traditional Chinese medicine to treat cancer, suggesting that water soluble constituents from these leaves may possess anticancer properties. Interestingly, hydrophilic paclitaxel derivatives, as opposed to paclitaxel itself, can be
Anticancer activity of an extract from needles and twigs of Taxus cuspidata and its synergistic effect as a cocktail with 5-fluorouracil.

Prijava / prijava
BACKGROUND
Botanical medicines are increasingly combined with chemotherapeutics as anticancer drug cocktails. This study aimed to assess the chemotherapeutic potential of an extract of Taxus cuspidata (TC) needles and twigs produced by artificial cuttage and its co-effects as a cocktail with
Aspergillus niger var. taxi, a new species variant of taxol-producing fungus isolated from Taxus cuspidata in China.

OBJECTIVE
To characterize and identify a new taxol-producing fungal strain HD86-9 isolated from Taxus cuspidata in China.
RESULTS
Taxol extracted from strain HD86-9 was identified by HPLC and MS analyses. Strain HD86-9 was cultured and its morphology and phenotypes were described. HD86-9 displayed

OBJECTIVE
Taxus cuspidata (Taxaceae), which is well known for the effective anticancer metabolite paclitaxel (e.g., taxol), is an evergreen needle-leaved tree widely distributed in eastern Eurasia including Japan. We developed 15 microsatellite markers from this species and confirmed their utility
A comparative optical aggregometry study of antiplatelet activity of taxanes from Taxus cuspidata.

Prijava / prijava
Platelets are highly reactive components of the circulatory system. The cytoskeleton of a platelet is an important structure for platelet aggregation as stimulated by several agonists. An anticancer agent, taxol, has been suggested to exert platelet anti-aggregating activity by stabilizing
Molecular cloning and characterization of the yew gene encoding squalene synthase from Taxus cuspidata.

Prijava / prijava
The enzyme squalene synthase (EC 2.5.1.21) catalyzes a reductive dimerization of two farnesyl diphosphate (FPP) molecules into squalene, a key precursor for the sterol and triterpene biosynthesis. A full-length cDNA encoding squalene synthase (designated as TcSqS) was isolated from Taxus cuspidata,
Phenolic Compounds of Catalpa speciosa, Taxus cuspidate, and Magnolia acuminata have Antioxidant and Anticancer Activity.

Prijava / prijava
Tree bark represents an important source of medicinal compounds that may be useful for cancer therapy. In the current study, high-performance liquid chromatography with diode-array detection (HPLC-DAD) was used to determine the profile of the phenolic compounds of Catalpa speciosa, Taxus
Iso-Seq analysis of the Taxus cuspidata transcriptome reveals the complexity of Taxol biosynthesis.

Extraction, Purification, and Biological Activities of Polysaccharides from Branches and Leaves of Taxus cuspidata S. et Z.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Taxus cuspidata S. et Z. is an excellent natural source of bioactive polysaccharides and has various biological activities. The objective of this study was to evaluate the effect of antidiabetic and antitumor activities of polysaccharides from Taxus cuspidata branches and leaves (TCBL)
Highly increased cellular accumulation of vincristine, a useful hydrophobic antitumor-drug, in multidrug-resistant solid cancer cells induced by a simply reduced taxinine.

Prijava / prijava
Regio- and/or chemo-selective reductions of taxinine (1a), a taxane diterpenoid readily obtainable from the needles of a Japanese yew (Taxus cuspidata), at the 5-O-cinnamoyl and 4-exo-methylene moieties have been accomplished by the catalytic hydrogenation over Pd/C or Rh/C to obtain
Screening of species of the endophytic fungus Phomopsis for the production of the anticancer drug taxol.

Prijava / prijava
Three different strains of the endophytic fungus Phomopsis were isolated from the healthy leaves of Taxus cuspidata (Japanese yew), Ginkgo biloba (ginkgo or maidenhair tree) and Larix leptolepis (Japanese larch) and screened for the production of taxol on a modified liquid medium for the first time.

Prijava / prijava
Callus cultures of Taxus cuspidata and Taxus canadensis were induced using different tissue explants including green and red arils, seed contents, young stems and needles. Callus derived from stem segments displayed the best growth in defined media. The culture medium was supplemented with reducing
Jasmonate-responsive expression of paclitaxel biosynthesis genes in Taxus cuspidata cultured cells is negatively regulated by the bHLH transcription factors TcJAMYC1, TcJAMYC2, and TcJAMYC4.

Taxus cell suspension culture is a sustainable technology for the industrial production of paclitaxel (Taxol®), a highly modified diterpene anti-cancer agent. The methyl jasmonate (MJ)-mediated paclitaxel biosynthetic pathway is not fully characterized, making metabolic engineering efforts
Relationship of viability and apoptosis to taxol production in Taxus sp. suspension cultures elicited with methyl jasmonate.

Prijava / prijava
Taxus cuspidata P991 in plant cell suspension culture is capable of producing the important anticancer agent Taxol (paclitaxel) and related taxanes. High-level production is obtained by elicitation with methyl jasmonate, but successful elicitation leads to loss of cell viability that cannot be
Cloning, heterologous expression, and characterization of a phenylalanine aminomutase involved in Taxol biosynthesis.
Samo registrirani uporabniki lahko prevajajo članke
Prijava / prijava
Biosynthesis of the N-benzoyl phenylisoserinoyl side chain of the anticancer drug Taxol starts with the conversion of 2S-alpha-phenylalanine to 3R-beta-phenylalanine by phenylalanine aminomutase (PAM). A gene cloning approach was based on the assumption that PAM would resemble the well known plant
