We have previously shown that the human genome includes hundreds of genes coding for putative factors related to the Krüppel zinc-finger protein, which regulates Drosophila segmentation. We report herein that about one-third of these genes code for proteins that share a very conserved region of about 75 amino acids in their N-terminal nonfinger portion.(More)
KRAB zinc-finger proteins (KRAB-ZFPs) constitute a large subfamily of ZFPs of the Krüppel C2H2 type. KRAB (Krüppel-associated box) is an evolutionarily conserved protein domain found N-terminally with respect to the finger repeats. We report here the characterization of a particular subgroup of highly related human KRAB-ZFPs. ZNF91 is one representative of(More)
We previously identified the ZNF85 (HPF4) KRAB zinc finger gene, a member of the human ZNF91 family. Here, we show that the ZNF85 gene is highly expressed in normal adult testis, in seminomas, and in the NT2/D1 teratocarcinoma cell line. Immunocytochemical localization of a panel of beta-Gal/ZNF85 fusion proteins revealed that ZNF85 contains at least one(More)
BACKGROUND The HIV-1 protease mutation I50 L causes atazanavir resistance but increases susceptibility to other PIs. Predicted phenotypic FC values were obtained from viral genotypes, using the virtual Phenotype-LM bioinformatics tool (powering vircoTYPE). OBJECTIVE To evaluate I50 L's effect on susceptibility to 8 PIs, in a large genotype database. (More)
Our aim was to identify new human proteins with potential DNA binding activity, related to the Krüppel protein which regulates Drosophila segmentation. We screened a human placenta cDNA library and a human genomic DNA library with a synthetic oligonucleotide probe corresponding to the H/C link region that connects finger loops in the multifingered Krüppel(More)
An open, non-comparative multicentre study was conducted at 36 sites in six countries to test the efficacy and safety of piperacillin/tazobactam in the therapy of lower respiratory tract infections. Piperacillin 4 g and tazobactam 500 mg were administered intravenously every 8 h for a minimum of five days. Two hundred and thirty patients were enrolled: 133(More)
BACKGROUND Non-nucleoside reverse transcriptase inhibitors (NNRTIs) are an important component of antiretroviral therapy for HIV type-1 (HIV-1)-infected patients. Development of NNRTI resistance can lead to treatment failure and is conferred by the presence of specific resistance-associated mutations (RAMs) in the reverse transcriptase. In addition to the(More)
Linear regression modeling on a database of HIV-1 genotypes and phenotypes was applied to predict the HIV-1 resistance phenotype from the viral genotype. In this approach, the phenotypic measurement is estimated as the weighted sum of the effects of individual mutations. Higher order interaction terms (mutation pairs) were included to account for(More)
The clinical utility of HIV-1 resistance testing is dependent upon accurate interpretation and application of results. The development of clinical cut-offs (CCOs) for most HIV antiretroviral drugs assessed by the vircoTYPE HIV-1 resistance test has been described previously. Updated CCOs based on new methodology and new data from clinical cohorts and(More)
OBJECTIVE Missense mutations in HIV-1 reverse transcriptase are frequently selected in response to therapy; we examined whether silent mutations were also selected for by HIV therapy. DESIGN Retrospective, observational analysis. Biochemical assays. METHODS A comparison of the reverse transcriptase gene, from antiretroviral- naive (N = 812) and(More)
