摘要:
The present invention is related to methods and for producing higher titers of recombinant protein in a modified yeast host cell, for example Pichia pastoris, wherein the modified yeast cell lacks vacuolar sorting activity or has decreased vacuolar sorting activity relative to an unmodified yeast host cell of the same species. In particular embodiments vacuolar sorting activity is reduced or eliminated by deletion or disruption of a gene encoding Vps10 or a Vps10 homolog. The invention is also related to the modified yeast cells which are modified in accordance with the methods disclosed herein.
摘要:
Described is a method for increasing the N-glycosylation site occupancy of a therapeutic glycoprotein produced in recombinant host cells modified as described herein and genetically engineered to express the glycoprotein compared to the N-glycosylation site occupancy of the therapeutic glycoprotein produced in a recombinant host cell not modified as described herein. In particular, the method provides recombinant host cells that overexpress a heterologous single-subunit oligosaccharyltransferase, which in particular embodiments is capable of functionally suppressing the lethal phenotype of a mutation of at least one essential protein of the yeast oligosaccharyltransferase (OTase) complex, for example, the Leishmania major STT3D protein, in the presence of expression of the host cell genes encoding the endogenous OTase complex. The method is useful for both producing therapeutic glycoproteins with increased N-glycosylation site occupancy in lower eukaryote cells such as yeast and filamentous fungi and in higher eukaryote cells such as plant and insect cells and mammalian cells.
摘要:
Lower eukaryote host cells in which an endogenous or heterologous Ca2+ ATPase is overexpressed are described. Also described are lower eukaryote host cells in which a calreticulin and/or ERp57 protein are overexpressed. These host cells are useful for producing recombinant glycoproteins that have reduced O-glycosylation.

We disclose a method of inhibiting activity of adenylyl cyclase or guanylyl cyclase in a mammal by administering to the mammal an amount of a composition effective to inhibit the activity, wherein the composition contains at least one compound selected from the group consisting of structural formulae (Ia) and (Ib) and salts thereof, wherein R1 is —H or has the structure —C(═O)R8; R2 is ═O or has the structure —OC(═O)R9; and R3, R4, R5, R6, and R7 are each independently selected from the group consisting of —H, —NO2, formula (I), -halogen, —OC(═O)R9, —OR9, —OH, —R8OH, —CH3, —OC(═O)CH2Ph, formulae (II), (III), (IV), —OPh, —CF3, —R8, —C(═O)OR9, -Ph, —R8Ph, formulae (V), (VI), (VII), (VIII), (IX), (X), (XI), (XII), (XIII), (XIV), (XV), (XVI), (XVII), (XVIII), (XIX), (XX), and (XXI), wherein each R8 is independently a linear or branched hydrocarbon group having from 1 to 4 carbon atoms and each R9 is independently a hydrocarbon group having from 1 to 2 carbon atoms. Administering the composition can be used to treat a disease in a mammal mediated by activity of adenylyl cyclase or guanylyl cyclase and effected by a toxin produced by a pathogenic organism or to reduce cyclic AMP or cyclic GMP levels in a mammal in need of reduction thereof. The composition can also be administered to mammalian cells in vitro. The above methods of inhibiting activity of adenylyl cyclase or guanylyl cyclase and treating diseases via such inhibition can be effective without prolonged treatment, have reversible effects, have low or no toxicity, are highly potent, are unlikely to have side effects, do not act on purinergic receptors, or can negate pathogenic toxins independently of whether the pathogenic organism survives.
摘要:
The present invention relates to the isolation of DNA regulatory regions of the malate synthase 1 gene (MLS1) from the yeast, Pichia pastoris. The present invention further relates to the expression of heterologous proteins which have been introduced into a P. pastoris host cell and can be expressed under the regulation of the MLS1 5′ regulatory promoter and MLS1 3′regulatory terminator regions. The MLS1 promoter is repressed in media containing glucose and derepressed under glucose starvation conditions or when acetate is present.
摘要:
Provided are a network-based robot control system and a robot velocity control method in the network-based robot control system. A client calculates a robot control velocity according to its reception state of video data frames captured by a robot, generates a robot control message including the calculated robot control velocity, and transmits the robot control message to the robot. The robot then changes its velocity according to the robot control velocity included in the received robot control message. In this way, the velocity of the robot is controlled according to the video data reception state of the client, thereby allowing a user to easily control the robot regardless of the performance of the client.
