In four infants with renal tubular acidosis (RTA), including three with apparently classic RTA and one with Fanconi syndrome (FS), the physiologic character of the renal acidification defect was investigated. In two of the infants with apparently classic RTA, the acidification defect was physiologically separable from that described in both adult patients and children with classic RTA (type 1 R...
The replication and transcription activator (RTA) of Kaposi's sarcoma-associated herpesvirus (KSHV), K-RTA, is a lytic switch protein that moderates the reactivation process of KSHV latency. By mass spectrometric analysis of affinity purified K-RTA, we showed that Thr-513 or Thr-514 was the primary in vivo phosphorylation site. Thr-513 and Thr-514 are proximal to the nuclear localization signal...
Replication and transcription activator (Rta), a key protein expressed by Epstein-Barr virus (EBV) during the immediate-early stage of the lytic cycle, is responsible for the activation of viral lytic genes. In this study, GST-pulldown and coimmunoprecipitation assays showed that Rta interacts in vitro and in vivo with TRIM5α, a host factor known to be involved in the restriction of retroviral ...
After endocytic uptake by mammalian cells, the heterodimeric plant toxin ricin is transported to the endoplasmic reticulum (ER), where the ricin A chain (RTA) must cross the ER membrane to reach its ribosomal substrates. Here, using gel filtration chromatography, sedimentation, fluorescence, fluorescence resonance energy transfer, and circular dichroism, we show that both fluorescently labeled ...
Recent studies have shown that cyclosporin A (CsA) may affect ricin A-chain immunotoxin (RTA-IT) therapy. In this study, we evaluated the ability of CsA and its nonirnmunosuppressive analog. SDZ PSC 833, to enhance anti-CD5 T l O l RTA-ITS in vitro. Both 4 pmol/L CsA and 4 pmol/L SDZ PSC 833 significantly and specifically enhanced the cytotoxic activity of T101 RTA-IT on the human lymphoblastic...
Herpesviruses are characterized as having two distinct life cycle phases: lytic replication and latency. The mechanisms of latency establishment and maintenance, as well as the switch from latency to lytic replication, are poorly understood. Human gammaherpesviruses, including Epstein-Barr virus (EBV) and human herpesvirus-8 (HHV-8), also known as Kaposi's sarcoma-associated herpesvirus (KSHV),...
results there was a significant positive correlation between increase in the monthly average temperature, the number of rainy days, and the number of frost days with the number of rta (p < 0.05). increased monthly average relative humidity, evaporation, and number of sunny days were negatively correlated with the frequency of rta (p < 0.05). we also observed an inverse significant correlation b...
OBJECTIVE To compare the effectiveness of tele-screening using a novel enhanced retinal thickness analyzer (RTA) with onsite routine ophthalmologic examination for diabetic retinopathy. RESEARCH DESIGN AND METHODS A consecutive series of 31 eyes from diabetic patients were included. All underwent ophthalmologic examination, including stereoscopic dilated funduscopy and scanning with the RTA. ...
Material and methods. We isolated DNA from 35 bone marrow biopsies, and measured the blood telomerase activity (RTA) in 21 of the patients. We performed immunostainigs for Ki-67, Bcl-2 and p53 on the biopsy samples in order to test the correlations to the RTA and MDS/EVI1 presence. MDS/EVI1 fusion was detected with touch-down-direct PCR, and RTA was measured using the “TeloTAGGG-PCRELISA-plus k...
