The identity of synaptically-enriched genes was investigated by comparing the abundance of various mRNAs in the synaptic and extra-synaptic regions of the same muscle fibers. The mRNAs for several known synaptic proteins were significantly elevated in the synaptic region when measured by real-time PCR. The synaptic mRNAs were then further analyzed using microarrays and real-time PCR to identify putative regulators of the neuromuscular junction (NMJ). MRF4 was the only member of the MyoD family that was concentrated at the mature NMJ, suggesting that it may have a unique role in the maintenance of post-synaptic specialization. Three potential regulators of the NMJ were identified and confirmed by real-time PCR: glia maturation factor gamma was concentrated at the NMJ whereas Unr protein and protein tyrosine phosphatase were repressed synaptically. The identification of synaptically-repressed genes may indicate that synaptic specialization is created by a combination of positive and negative signals.

Coordinated interactions between ovarian granulosa and theca cells are required for female endocrine function and fertility. To elucidate these interactions the regulation of the granulosa and theca cell transcriptomes during bovine antral follicle development were investigated. Granulosa cells and theca cells were isolated from small (<5 mm), medium (5-10 mm), and large (>10 mm) antral bovine follicles. A microarray analysis of 24,000 bovine genes revealed that granulosa cells and theca cells each had gene sets specific to small, medium and large follicle cells. Transcripts regulated (i.e., minimally changed 1.5-fold) during antral follicle development for the granulosa cells involved 446 genes and for theca cells 248 genes. Only 28 regulated genes were common to both granulosa and theca cells. Regulated genes were functionally categorized with a focus on growth factors and cytokines expressed and regulated by the two cell types. Candidate regulatory growth factor proteins mediating both paracrine and autocrine cell-cell interactions include macrophage inflammatory protein (MIP1 beta), teratocarcinoma-derived growth factor 1 (TDGF1), stromal derived growth factor 1 (SDF1; i.e., CXCL12), growth differentiation factor 8 (GDF8), glia maturation factor gamma (GMFG), osteopontin (SPP1), angiopoietin 4 (ANGPT4), and chemokine ligands (CCL 2, 3, 5, and 8). The current study examined granulosa cell and theca cell regulated genes associated with bovine antral follicle development and identified candidate growth factors potentially involved in the regulation of cell-cell interactions required for ovarian function.
