The cellular transcription factor E2f requires viral E1A and E4 gene products for increased DNA-binding activity and functions to stimulate adenovirus E2A gene expression.

Moreover, during competition, the effect of m7GTP seems to be accentuated, i.e., the inhibition of HeLa mRNA translation in the presence of the cap analog only is 29%, but when

The FeLV env glycoprotein expressed by recombinant FHV was processed and transported to the cell surface much as in FeLV infection, with the exception that proteolytic processing

of type I proteins (molecules with an N-terminal lumenal domain and a C-terminal cytoplasmic tail: N.u,Ci. topology [3]), particularly the influenza virus hemagglutinin (HA)

indicate that the wild-type bovine papillomavirus type 1 genome encodes an E2 repressor protein that moderates the viral transforming activity and allows maintenance of the viral DNA

Since most of the cell-associated virus was cleaved in the untreated culture (Fig. 2B, lane 3), it was theoretically possible that the s2 form of virus found in the medium

proliferation occurred in these cultures as soon as 2 days postinfection (Fig. 3), there was no detectable difference in the cytolytic capabilities of infected and uninfected cells

Moreover, we have also proposed another technique where a five-mode fiber is reduced to four modes and results in even higher (above 30%) effective index difference and also larger

To analyze the glycoproteins synthesized after vaccinia virus infection, HeLa cells were labeled with [3H]glucosamine from 0 to 4 and 4 to 8 h postinfection, and the proteins
