A nucleic acid vector comprising: a) a first construct comprising: (i) two or more first transcriptional elements comprising a TATA box promoter element comprising nucleotides 148-153 of SEQ ID NO:1 in combination with four copies of the GAL4 upstream activating sequence comprising nucleotides 19-35, 38-54, 57-73, and 76-92 of SEQ ID NO:1, (ii) one or more first translational enhancer elements (TEEs) comprising one random oligonucleotide sequence comprising nucleotides 190-207 of SEQ ID NO:1, and (iii) a first cistron comprising nucleotides 214-897 of SEQ ID NO:1 and encoding a first gene product, wherein the first gene product is a yeast regulatory protein GAL4/viral fusion protein 16 (GAL4/VP16), wherein said random oligonucleotide sequence is interposed between the two or more transcriptional elements and the first cistron; b) a second construct comprising: (i) at least one transcriptional element comprising a TATA box promoter element comprising nucleotides 1347-1352 of SEQ ID NO:1 and one or more UAS sequences having a sequence selected from the group consisting of nucleotides 1224-1240, 1243-1259, 1262-1278, and 1281-1297 of SEQ ID NO:1, (ii) one or more second TEEs, and (iii) a second cistron encoding a second gene product, wherein the one or more second TEEs is interposed between the at least one transcriptional element and the second cistron; and c) a third construct comprising: (i) at least one transcriptional element, (ii) one or more third TEEs, and (iii) a third cistron encoding a third gene product that increases translation of mRNA encoded by the first and second constructs by decreasing host mRNA translation, wherein the one or more third TEEs is interposed between the at least one transcriptional element and the third cistron, wherein the first, second, and third constructs are functionally linked, wherein the expression of the GAL4/VP16 results in binding to one or more UAS sequence and transcriptional amplification of the first cistron and the second cistron, and wherein at least one of the TEEs of each construct is resistant to the activity of the gene product of the third cistron. a) a first construct comprising: (i) two or more first transcriptional elements comprising a TATA box promoter element comprising nucleotides 148-153 of SEQ ID NO:1 in combination with four copies of the GAL4 upstream activating sequence comprising nucleotides 19-35, 38-54, 57-73, and 76-92 of SEQ ID NO:1, (ii) one or more first translational enhancer elements (TEEs) comprising one random oligonucleotide sequence comprising nucleotides 190-207 of SEQ ID NO:1, and (iii) a first cistron comprising nucleotides 214-897 of SEQ ID NO:1 and encoding a first gene product, wherein the first gene product is a yeast regulatory protein GAL4/viral fusion protein 16 (GAL4/VP16), wherein said random oligonucleotide sequence is interposed between the two or more transcriptional elements and the first cistron; b) a second construct comprising: (i) at least one transcriptional element comprising a TATA box promoter element comprising nucleotides 1347-1352 of SEQ ID NO:1 and one or more UAS sequences having a sequence selected from the group consisting of nucleotides 1224-1240, 1243-1259, 1262-1278, and 1281-1297 of SEQ ID NO:1, (ii) one or more second TEEs, and (iii) a second cistron encoding a second gene product, wherein the one or more second TEEs is interposed between the at least one transcriptional element and the second cistron; and c) a third construct comprising: (i) at least one transcriptional element, (ii) one or more third TEEs, and (iii) a third cistron encoding a third gene product that increases translation of mRNA encoded by the first and second constructs by decreasing host mRNA translation, wherein the one or more third TEEs is interposed between the at least one transcriptional element and the third cistron,
