Seven scientists at the cutting edge of molecular biology--from DNA mismatch repair to cytokine signal transduction--will share their insights with the NIH community this fall, thanks to the efforts of the NIH Fellows Committee. The First NIH Postdoctoral and Clinical Fellows Symposium will be held at Natcher Auditorium from 8:00 a.m. to 5:15 p.m. on Oct. 12. The speakers are Ari Helenius of Yale University in New Haven, Conn., "The endoplasmic reticulum as a protein-folding compartment"; Kevin Campbell of the University of Iowa College of Medicine in Des Moines, "Molecular basis of muscular dystrophy: disruption of the cytoskeleton-extracellular matrix linkage"; Tom Maniatis of Harvard University in Cambridge, Mass., "Regulating the activities of the Rel family of transcriptional activator proteins"; John O'Shea of NIAMS, "Cytokine signal transduction: JAKs, STATs, and clinical implications"; Melanie Spriggs of Immunex Corp. of Seattle, "Viral genes that modulate host immune function"; Joseph Nevins of Duke University in Durham, N.C., "Alteration of cell-growth control by DNA tumor virus oncoproteins"; and Paul Modrich, also of Duke, "Mismatch repair and genetic stability in human cells." For more information on the symposium, which is being supported with funds from the institutes, centers, and divisions, contact Courtney Jones at the Office of Education (phone: 496-3887).
