Current Research and Teaching

Professor Lyerla has retired from teaching full time, but maintains a research laboratory at Clark and teaches occasionally on a course-by-course basis. Research in my laboratory concerns the expression of mutant and variant characters in established and primary cell cultures from vertebrate organisms. The haploid cell line from Rana pipiensembryos, ICR2A, is used for basic studies from an established line, while cultures of lung cell macrophages from mice that serve as animal models for Hermansky-Pudlak (HPS) and Chediak-Higashi Syndromes(CHS) are used for primary cell culture work.

Vertebrate cell culture is an important tool for basic and biomedical studies, and some mastery of the techniques used for the research is needed in order to probe the molecular basis of questions concerning chromosome stability in vitro, the development of drug resistance, mutant effects on secretory pathways leading to serious genetic disorders. My laboratory is concerned with each of these issues, and using cultured cells to explore them in debth with specific goals as to possible outcomes and future research.
