Improving promiscuous mammalian cell entry by the baculovirus Autographa californica multiple nuclear polyhedrosis virus
The insect baculovirus AcMNPV (Autographa californica multiple nuclear polyhedrosis virus) enters many mammalian cell lines, prompting its application as a general eukaryotic gene delivery agent, but the basis of entry is poorly understood. For adherent mammalian cells, we show that entry is favoured by low pH and by increasing the available cell-surface area through a transient release from th...
متن کاملA baculovirus vector derived from immediately early gene promoter of Autographa californica nuclear polyhedrosis virus.
A transfer vector was constructed in which the neomycin resistance (neo) gene was under the control of a copy of Autographa californica nuclear polyhedrosis virus (AcMNPV) IE1 gene promoter at the p10 locus. After cotransfection of Spodoptera frugiperda (Sf9) cells with the transfer vector and infectious AcMNPV DNA, the recombinant virus-containing neo gene was selected by serial passage of the...
متن کاملIn vitro transactivation of baculovirus early genes by nuclear extracts from Autographa californica nuclear polyhedrosis virus-infected Spodoptera frugiperda cells.
Nuclear extracts, prepared from Autographa californica nuclear polyhedrosis virus-infected Spodoptera frugiperda cells during a time course of infection, were analyzed for activation of early gene transcription and for late gene transcription. The templates used in the in vitro transcription assays contained promoters for baculovirus genes that have been classified as immediate early, delayed e...
متن کاملCross infectivity of baculovirus, Spilarctia obliqua nuclear polyhedrosis virus against mulberry pest, Porthesia xanthorrhoea Kollar.
Spilarctia obliqua nucleopolyhedrosis virus (SoNPV) has been found effective against S. obliqua (Walker) as well as Porthesia xanthorrhoea Kollar. LC50 concentration of S. obliqua SoNPV against S. obliqua and P. xanthorrhoea was 2.5 x 10(4) and 3.7 x 10(4) POBs/ml, respectively. LT50 of SoNPV against S. obliqua was 5.73 days, while it was 6.98 days for P. xanthorrhoea. Cross infectivity of SoNP...
متن کاملCharacterization of v-cath, a cathepsin L-like proteinase expressed by the baculovirus Autographa californica multiple nuclear polyhedrosis virus.
Autographa californica multiple nuclear polyhedrosis virus (AcMNPV) contains a 966 bp ORF that encodes a papain type cysteine proteinase with cathepsin L-like characteristics. Using Western blot analysis of infected cell extracts we showed that v-cath proteinase has 35.5 kDa and 32 kDa precursor forms which are processed to a 27.5 kDa mature form in a manner characteristic of papain and catheps...
