The purpose of the present study was to assess the effectiveness of a parent training program designed to alter interactions of parents and their noncompliant children. Mother-child pairs were assigned to either a treatment or a waiting list control group. Parent training was conducted in a controlled learning environment. The following pre- and posttreatment measures were collected: clinic observational data, home observational data, and parent verbal report measures. The results indicated that both parents and children in the treatment group demonstrated multiple behavior changes in the clinic and home, whereas the control group did not change over the waiting period. Both treatment and control group mothers demonstrated positive changes on most of the parent verbal report measures.

We have investigated two patients with acquired chromosomal rearrangements, a male presenting with a t(1;9)(p34;q34) and B cell progenitor acute lymphoid leukemia and a female presenting with a t(8;12)(p11;q15) and the 8p11 myeloproliferative syndrome. We determined that the t(1;9) fused ABL to SFPQ (also known as PSF), a gene mapping to 1p34 that encodes a polypyrimidine tract-binding protein-associated splicing factor. The t(8;12) fused CPSF6, a cleavage and polyadenylation specificity factor, to FGFR1. The fusions were confirmed by amplification of the genomic breakpoints and RT-PCR. The predicted oncogenic products of these fusions, SFPQ-ABL and CPSF6-FGFR1, are in-frame and encode the N-terminal domain of the partner protein and the entire tyrosine kinase domain and C-terminal sequences of ABL and FGFR1. SFPQ interacts with two FGFR1 fusion partners, ZNF198 and CPSF6, that are functionally related to the recurrent PDGFRalpha partner FIP1L1. Our findings thus identify a group of proteins that are important for pre-mRNA processing as fusion partners for tyrosine kinases in hematological malignancies.

We have designed a set of nine plasmids containing the Bacillus pumilis cat gene with one of three Shine-Dalgarno (SD) sequences (weak, strong or stronger) and one of three initiation codons (AUG, GUG or UUG). These constructions have been used to determine the effect of ribosomal protein S1, SD and initiation codon sequences and Escherichia coli ribosomal protein S1 on translation in vitro by E. coli and B. subtilis ribosomes. Translation of these nine constructions was determined with three types of ribosomes: E. coli containing ribosomal protein S1, E. coli depleted of S1, and B. subtilis which is naturally free of S1. E. coli ribosomes were able to translate all nine transcripts with variable efficiencies. B. subtilis and S1-depleted E. coli ribosomes were similar to each other and differed from non-depleted E. coli ribosomes in that they required strong or stronger SD sequences and were unable to translate any of the weak transcripts. Addition of S1 from either E. coli or Micrococcus luteus, a Gram-positive bacterium, enabled S1-depleted E. coli ribosomes to translate mRNAs with weak SD sequences but had no effect on B. subtilis ribosomes. AUG was the preferred initiation codon for all ribosome types; however, B. subtilis ribosomes showed greater tolerance for the non-AUG codons than either type of E. coli ribosome. The presence of a strong or stronger SD sequence increased the efficiency by which E. coli ribosomes could utilize non-AUG codons.(ABSTRACT TRUNCATED AT 250 WORDS)
