Master of Education in Teaching Program with an Emphasis in the Health Sciences

Introduction: Concerns about the quality of physician education have changed current medical education practices. Learners must demonstrate competency in core areas, rather than solely participating in educational activities. Academic medical institutions are challenged with identifying leaders to direct curricular and evaluation reforms. An innovative partnership between the University of Houston College of Education and Baylor College of Medicine, the University of Texas Medical School at Houston, and the University of Texas Dental Branch at Houston offers a Masters of Education in Teaching degree with an emphasis in Health Sciences. Courses encompass fundamental areas including curriculum, instruction, technology, measurement, research design and statistics. [See PDF for complete abstract]

Selective elevation of c-{\it myc} RNA transcripts during clonal evolution of N-methyl-N-nitrosourea induced thymic lymphomas in AKR/J mice

Untreated AKR mice develop spontaneous thymic lymphomas by 6-12 months of age. Lymphoma development is accelerated when young mice are injected with the carcinogen N-methyl-N-nitrosourea (MNU). Selected molecular and cellular events were compared during the latent period preceding "spontaneous" (retrovirally-induced) and MNU-induced thymic lymphoma development in AKR mice. These studies were undertaken to test the hypothesis that thymic lymphomas induced in the same inbred mouse strain by endogenous retroviruses and by a chemical carcinogen develop by different mechanisms.^ Immunofluorescence analysis of differentiation antigens showed that most MNU-induced lymphomas express an immature CD4-8+ profile. In contrast, spontaneous lymphomas represent each of the major lymphocyte subsets. These data suggest involvement of different target populations in MNU-induced and spontaneous lymphomas. Analyses at intervals after MNU treatment revealed selective expansion of the CD4-8+ J11d+ thymocyte subset at 8-10 weeks post-MNU in 68% of the animals examined, suggesting that these cells are targets for MNU-induced lymphomagenesis. Untreated age-matched animals showed no selective expansion of thymocyte subsets.^ Previous data have shown that both spontaneous and MNU-induced lymphomas are monoclonal or oligoclonal. Distinct rearrangement patterns of the J$\sb2$ region of the T-cell receptor $\beta$-chain showed emergence of clonal thymocyte populations beginning at 6-7 weeks after MNU treatment. However, lymphocytes from untreated animals showed no evidence of clonal expansion at the time intervals investigated.^ Activation of c-myc frequently occurs during development of B- and T- cell lymphomas. Both spontaneous and MNU-induced lymphomas showed increased c-myc transcript levels. Increased c-myc transcription was first detected at 6 weeks post-MNU, and persisted throughout the latent period. However, untreated animals showed no increases in c-myc transcripts at the time intervals examined. Another nuclear oncogene, c-fos, did not display a similar change in RNA transcription during the latent period.^ These results supports the hypothesis that MNU-induced and spontaneous tumors develop by multi-step pathways which are distinct with respect to the target cell population affected. Clonal emergence and c-myc deregulation are important steps in the development of both MNU-induced and spontaneous tumors, but the onset of these events is later in spontaneous tumor development. ^

Molecular and biochemical analysis of the {\it Drosophila\/} segmentation gene {\it runt\/}

Genetic evidence has indicated that the segmentation gene runt plays a key role in regulating gene expression of the pair-rule genes hairy, even-skipped, and fushi tarazu. In contrast to other pair-rule genes, sequence data of the runt open reading frame did not reveal homologies to DNA-binding motifs of known transcriptional regulatory proteins. This thesis project examined several properties of the runt gene based on the sequence of the transcription unit, including the subcellular localization of the protein in vivo, its ability to bind DNA, and the functionality of a putative nucleotide binding domain.^ A runt-specific antibody was generated and used to demonstrate that runt is localized in the nucleus. Since the precise overlap of the pair-rule stripes is thought to be critical for the determination of cellular identity along the anterior-posterior axis, phasing of early runt expression in the blastoderm was examined with regard to the segmentation genes hairy, even-skipped, and fushi tarazu. runt was also expressed at later stages of embryogenesis, including expression in neuroblasts, and ganglion mother cells of the developing nervous system. Expression at this stage was required for the subsequent formation of specific neurons and runt was extensively expressed in the central and peripheral nervous systems.^ Several experiments were done to address the biochemical function of the runt protein. A direct interaction of runt with DNA was first examined. Although bacterial expressed runt was found to bind dsDNA-cellulose, subsequent experiments failed to detect sequence-specific interactions with DNA. Inter-species conservation of the putative nucleotide binding domain suggested that this region was functionally important, and runt protein bound a labeled ATP analog with high affinity in vitro. Finally, the effect of substitution of a critical residue of the nucleotide binding domain on runt activity was examined in vivo. Ectopic expression of the mutant protein indicated that this conserved substitution altered, but did not eliminate, runt activity as evaluated by segmentation phenotype and viability. ^

The effect of v-{\it mos\/} expression on the regulation of the {\it fos\/} promoter in 490N3T cells

The v-mos oncogene acquired by Moloney murine sarcoma viruses by recombination with the c-mos proto-oncogene encodes a 37kD cytoplasmic serine/threonine protein kinase which can phosphorylate tubulin and vimentin, as well as the cyclin B component of the maturation promotion factor complex (MPF). Our earliest experiments asked whether the v-mos protein could activate the transcription of transin. Since the transcription of transin was known to be mediated by both fos-dependent and fos-independent pathways, it seemed possible that the induction of transin transcription by v-mos might be mediated by p55$\sp{\rm c-}\sp{fos}$. Surprisingly, when we examined the effect of v-mos on the fos promoter, we observed a significant inhibition of transcription in 49ON3T cells, a subclone of N1H3T3 mouse fibroblasts.^ In this thesis we show that in mouse 49ON3T cells, transcription from the fos promoter is up to 10-fold repressed in the presence of v-mos. Moreover, in this cell line several other transforming constructs (v-ras, v-src, neu) also cause repression of the fos promoter. Interestingly, nontransforming oncogenes (e.g. myc) do not repress fos transcription. The repressive effect was lost in v-mos mutants lacking in ATP-binding or kinase domain, arguing that the effect on fos transcription was mediated by v-mos transforming kinase activity. As mos is a cytoplasmic protein, it was assumed that transcriptional repression was mediated by conversion of a transcriptional regulator to a repressor by mos-induced phosphorylation. As a first approximation of the identity of this factor, we mapped the position of the mos effect on the fos promoter using reporter (CAT) constructs. We found that repression was mediated by regions $-$221 to $-$106 and $-$122 to $-$65 relative to the fos transcriptional start site, both of which regions regulate baseline fos transcription. There are direct repeats containing E2F transcriptional activator/repressor recognition motifs in these regions which bind similar nuclear proteins independently of v-mos presence or absence. Our data show that the contribution of the direct repeat to baseline fos transcription is mediated by these E2F sites with perhaps some contribution from the overlapping retinoblastoma control element (RCE). We have shown that there is a separate DNA protein interaction in the direct repeat which is more pronounced in the presence of v-mos. The recognition site for this protein, which we speculate mediates the mos-induced downregulation of fos transcription, overlaps but is distinct from the E2F and RCE binding sites.
