Application of mutated inbred animal models in the experimental teaching of medical genetics / 中国比较医学杂志

ABSTRACT

Objective Mutated inbred animal model is introduced to the practical course of genetic diagnosis in the hope that medical students are able to apply what they have learned to clinical cases, based on a deep understanding of principle and technology on gene mutation detection. Methods We integrated DNA extraction, polymerase chain reaction, agarose gel electrophoresis, and gel imaging analysis into a comprehensive experiment and arranged 4-year-programme undergraduates majoring in preclinical medical sciences to conduct it with the purpose of investigating the internal relations between phenotype and genotype in a hairless Uncv mouse model. Subsequently, the questionnaire aimed at evaluating learning effect on the part of students was handed out and their feedbacks were analyzed. Results More than 90% of respondents are satisfied with the general learning effect. Especially, 98. 7% of students support the enhancing effect of the new teaching mode on their research skills and 96% consider the practical course helpful to their problem-solving ability. Conclusions The introduction of mutated inbred animal model to the practical system of molecular diagnostics proves beneficial to boost students' learning effect and scientific research quality. Our practice also provokes thoughts on the further utilization of animal models in teaching system of medical sciences.
