Pomalidomide in the treatment of multiple myeloma: design, development and place in therapy.

Multiple myeloma is a very heterogeneous disease with variable survival. Despite recent progress and the widespread use of new agents, patients with relapsed and refractory disease have a poor outcome. Immunomodulatory drugs play a key role in both the front-line and the relapsed/refractory setting.

[Molecular detection of the BCR-ABL gen by RT-PCR in Costa Rican children with leukemia].

Many leukemias could have chromosomic translocations and according to the transcripts formed by the genes involved, the patients present an specific phenotype of the leukemia. We show the first results of the investigation of the gen BCR-ABL using RT-PCR, in order to look for the t(9;22)(q34;q11) in pediatric leukemic children. We studied in total 55 patients, 6 (10.

The mother superior mutation ablates foxd3 activity in neural crest progenitor cells and depletes neural crest derivatives in zebrafish.

The zebrafish mutation mother superior (mosm188) leads to a depletion of neural crest (NC) derivatives including the craniofacial cartilage skeleton, the peripheral nervous system (sympathetic neurons, dorsal root ganglia, enteric neurons), and pigment cells. The loss of derivatives is preceded by a reduction in NC-expressed transcription factors, snail1b, sox9b, sox10, and a specific loss of foxd3 expression in NC progenitor cells. We employed genetic linkage analysis and physical mapping to place the mosm188 mutation on zebrafish chromosome 6 in the vicinity of the foxd3 gene.
