A summer program was created for undergraduates and graduate students that teaches bioinformatics concepts, offers skills in professional development, and provides research opportunities in academic and industrial institutions. We estimate that 34 of 38 graduates (89%) are in a career trajectory that will use bioinformatics. Evidence from open-ended research mentor and student survey responses, student exit interview responses, and research mentor exit interview/survey responses identified skills and knowledge from the fields of computer science, biology, and mathematics that are critical for students considering bioinformatics research.

To catalog factors that may contribute to the completion of myogenesis, we have been looking for molecular differences between BC3H1 and C2C12 cells. Cells of the BC3H1 tumor line, though myogenic, are nonfusing, and withdraw from the cell cycle only reversibly, whereas cells of the C2C12 line fuse, differentiate terminally, and express several muscle-specific gene products that BC3H1 cells do not. Relative to C2C12 cells, BC3H1 cells underaccumulated cyclin-dependent kinase inhibitor p21 and underaccumulated transcripts for p21, GADD45, CDO, decorin, osteopontin, H19, fibronectin, and thrombospondin-1 (tsp-1).

cDNAs representing an endogenous C-type ecotropic murine leukemia virus were isolated from a cDNA library constructed to represent mRNAs present in BC3H1 myogenic cells but not in C2C12 myogenic cells. RNA blot hybridization analysis using the cDNA inserts as probes revealed that BC3H1 cells produce MuLV-related transcirpts of at least three different size classes. A polymerase chain reaction enhanced assay for reverse transcriptase activity revealed the presence of reverse transcriptase in a viral pellet from medium conditioned by BC3H1 cells.
