    Abstract: In metazoans, the nuclear export of bulk mRNAs is mediated by the export receptor TAP, together with its binding partner p15. A number of viral mRNAs, including the unspliced and partially spliced mRNA species of the human immunodeficiency virus (HIV), however, use an alternative export route via the importin beta-related export receptor CRM1. This raises the question of whether a subset of cellular mRNAs might be exported by CRM1 as well. To identify such mRNAs, we performed a systematic screen in different cell lines, using representational difference analyses of cDNA (cDNA-RDA). In HeLa and Cl-4 cells no cellular transcripts could be identified as exported via CRM1. In contrast, we found a number of CRM1-dependent mRNAs in Jurkat T cells, most of which are induced during a T cell response. One of the identified gene products, the dendritic cell marker CD83, was analyzed in detail. CD83 expression depends on a functional CRM1 pathway in activated Jurkat T cells as well as in a heterologous expression system, independent of activation. Our results point to an important role of the CRM1-dependent export pathway for the expression of CD83 and other genes under conditions of T cell activation. (c) 2006 Elsevier Ltd.

    Notes: Abstract Contemporary reports on surgery for horseshoe kidney (HK) still recommend isthmotomy and lateropexy to complete an open pyeloplasty. To evaluate whether simple Anderson-Hynes pyeloplasty without symphysiotomy is effective for relief of ureteropelvic junction obstruction (UPJO) in HK, we studied the records of ten children, two of whom had bilateral UPJO. Only one child presented with calculi; 11 units were operated upon for UPJO, 1 needed a partial nephrectomy. The surgical outcome was evaluated with emphasis on the changes in renal drainage and function assessed by ultrasonography and diuretic renal scans. Associated vesicoureteral reflux was observed more often (25%) than with UPJO in normal kidneys. Obstruction was caused by a crossing lower-pole vessel in three cases, a high ureteral insertion in two and narrowing of the UPJ 7. Postoperative follow-up (mean 5.5 years) revealed improved renal function and good drainage in all cases. Hydronephrosis vanished in 7, whereas grade 2 hydronephrosis remained in two children with former refluxive megaureter and grade 3 in one. All children are doing well and have no symptoms due to the persistent isthmus (Rovsing syndrome). It is concluded that simple Anderson-Hynes pyeloplasty via a flank incision is a highly effective and safe procedure for treating UPJO in HK.
