    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.

    Abstract: Breast cancer is a systemic disease with a primarily local component. Besides surgical resection and irradiation of the locoregional tumor setting, central therapeutic aim is the elimination of disseminated micrometastatic tumor cells using cytostatic and/or hormonal treatment. Nevertheless, in the course of time a majority of patients suffer from systemic recurrence in the form of distant metastases. Intriguingly, in this connection, intratumoral cytotoxic T lymphocytes might serve as independent predictors of treatment efficacy and clinical outcome. Loss of immune balance (tumor dormancy) during intensive cross talk between T cells and tumor cells in the bone marrow microenvironment is suggested one reason for distant metastatic relapse. In this clinical context, further supportive therapies become increasingly attractive, taking immunological features of breast cancer cells into special account. The present review aims to dissect bone marrow-derived cellular antitumor immune responses and translational immunologic treatment options regarding their actual relevance to patients' clinical benefit and their future directions in breast cancer management.

    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.

    Notes: Summary Tassel branch numbers of six crosses of maize (Zea mays L.) were analyzed to determine inheritance of this trait. Generation mean analyses were used to estimate genetic effects, and additive and nonadditive components of variance were calculated and evaluated for bias due to linkage. Both narrow-sense and broad-sense heritabilities were estimated. Additive genetic variance estimates were significant in five of the six crosses, whereas estimates of variance due to nonadditive components were significant in only three crosses. Additionally, estimates of additive variance components usually were larger than corresponding nonadditive components. There was no evidence for linkage bias in these estimates. Estimates of additive genetic effects were significant in four of six crosses, but significant dominance, additive × additive and additive × dominance effects also were detected. Additive, dominance, and epistatic gene action, therefore, all influenced the inheritance of tassel branch number, but additive gene action was most important. Both narrow-sense and broadsense heritability estimates were larger than those reported for other physiological traits of maize and corroborated conclusions concerning the importance of additive gene action inferred from analyses of genetic effects and variances. We concluded that selection for smalltasseled inbreds could be accomplished most easily through a mass-selection and/or pedigree-selection system. Production of a small-tasseled hybrid would require crossing of two small-tasseled inbreds. We proposed two genetic models to explain unexpected results obtained for two crosses. One model involved five interacting loci and the other employed two loci displaying only additive and additive × additive gene action.

    Notes: Abstract Cortisol and growth hormone (GH) secretion (spontaneous variations at night and the release induced by insulin hypoglycaemia) were investigated in 69 children and adolescents. Statistical analysis of approximately 600 pairs of cortisol and GH values in this study demonstrated that physiological fluctuations of cortisol do not alter GH secretion. A review of the literature shows that GH secretion is consistently depressed in Cushing's disease of central origin and in Cushing's syndrome due to adrenal carcinoma. When acutely administered, doses higher than 100 mg of cortisol (or equivalent amounts of other steroids) per adult are necessary to block GH secretion and the hormones have to be given several hours previously. In long-term steroid treatment, suppression of GH is observed in only 1 out of 3 patients. The effect apparently does not persist beyond elimination of the last dose, i.e. generally not longer than 12 to 24 h. These data can be taken as a rationale for intermittent or alternating dosage schedules, and for the use of short acting derivatives if long-term, high-dose steroid treatment is necessary in children. It remains to be established whether growth deficiency in exogenous hypercortisolism is due to suppression of GH secretion, decreased production of somatomedins, direct antagonism of the action of somatomedins on growing cartilage, or a combination of these mechanisms.
