Journal article (peer-reviewed)abstract
- The change of phenotypic traits in domestic animals and crops as a response to selective breeding mimics the much slower evolutionary change in natural populations. Here, we describe that the dominant white phenotype in domestic pigs is caused by two mutations in the KIT gene encoding the mast/stem cell growth factor receptor (MGF), one gene duplication associated with a partially dominant phenotype and a splice mutation in one of the copies leading to the fully dominant allele. The splice mutation is a G to A substitution in the first nucleotide of intron 17 and leads to skipping of exon 17. The duplication is most likely a regulatory mutation affecting KIT expression, whereas the splice mutation is expected to cause a receptor with impaired or absent tyrosine kinase activity. Immunocytochemistry showed that this variant form is expressed in 17- to 19-day-old pig embryos. Hundreds of millions of white pigs around the world are assumed to be heterozygous or homozygous for the two mutations.

Mobilization of Philadelphia-negative peripheral blood progenitor cells with chemotherapy and rhuG-CSF in chronic myelogenous leukaemia patients with a poor response to interferon-alpha
- 1998

In: British Journal of Haematology. - : Wiley. - 0007-1048 .- 1365-2141. ; 101:1, s. 111-8

Journal article (peer-reviewed)abstract
- The purpose of this cooperative study was to evaluate the quantity and quality of Ph1-negative progenitor cells mobilized in the peripheral blood of patients with chronic myelogenous leukaemia soon after aplasia induced by chemotherapy. 32 patients ineligible for allografting who were cytogenetically refractory to interferon-alpha (IFN-alpha) were entered into this study. The chronic phase varied widely, with a median duration of 17 months (range 3-90 months). All patients were treated with intensive conventional chemotherapy regimens and recombinant human granulocyte colony-stimulating factor (rhuG-CSF, lenograstim). Peripheral blood progenitor cells (PBPC) were harvested by leukaphereses during early recovery from chemotherapy-induced aplasia. A total of 119 leukaphereses were performed. Median numbers of CD34+ cells and CFU-GM collected were 2.04 x 10(6)/kg and 2 9 x 10(4)/kg, respectively. There was a significant correlation between white cell count and number of CD34+ cells in the leukaphereses (P = 0.0001, r2 = 0.41, n = 104). A strict correlation between the number of CD34+ cells and CFU-GM in the leukapheretic product (P = 0.0001, r2 = 0.39, n = 110) was observed. 21% of evaluable patients (6/29) achieved a complete cytogenetic remission in the leukapheretic product and the other four patients achieved a major cytogenetic response for an overall response of 35% (10/22 patients). To date, 16 patients have been autografted and are alive. Five of them are Ph1-negative (three patients) or partially Ph1-negative (two patients). In conclusion, despite the high-risk characteristics of this study population, Ph1-negative PBPC were successfully mobilized in more than one-quarter of patients using a chemotherapy plus rhuG-CSF regimen. The importance of this achievement is increased by the current lack of other practical methods of rescuing Ph-negative cells in such patients.

Spectroscopy at N=Z with EUROBALL III
- 1999

Conference paper (peer-reviewed)abstract
- A complete study of the nuclear structure by means of gamma spectroscopy requires, in addition to the high resolution gamma measurement and accurate DCO's or angular distributions, the information concerning the Electric or Magnetic character of the transition. This information for transitions in nuclei far from stability valley is now reachable in the new generation of Ge-arrays based in composite detectors. EUROBALL III is a good example with the high polarization sensitivity of the 90 degrees ring of Clovers. The Polarization correlations PCO's measured in coincidence with the Cluster detectors permits to investigate transitions in weakly populated nuclei. In this contribution we present results on medium mass N=Z nuclei measured with EUROBALL III coupled with light particle ancillary detectors.
