Developmental Biology RSM

BIOL20972 Developmental Biology RSM 10 Semester 2 Undergraduate Level 2 Karel Dorey Unit coordinator 1 FHEQ level (Framework for Higher Education Qualifications) ' Middle part of Bachelors ' European Credit Transfer & Accumulation System Rating : 5.0 This Research Skills Module is designed to develop your experimental design, report writing and practical skills. You will be introduced to developmental biology research techniques during four laboratory-based projects. You will use various model organisms such as Arabidopsis, zebrafish, Xenopus and fruit fly and learn different techniques such as DNA sequence analysis and immunohistochemistry. To introduce students to a selection of modern Developmental Biology research techniques and commonly used model organisms. To provide training in the design of experiments, the analysis and interpretation of data, the presentation of results and the maintenance of a professional lab book.  To build on students’ previous practical experience and to introduce new concepts. To provide training in the design of experiments, the analysis and interpretation of data, the presentation of results and the maintenance of a professional lab book. To help students develop relevant practical skills and provide experimental contexts that illustrate some of the theoretical models and concepts that will be taught in BIOL21371 (Organismal Genetics) and BIOL21172 (Principles of Developmental Biology). Students will develop skills in experimental design, time management within the laboratory, team working, the analysis and interpretation of data, and the presentation of data. They will also have a working knowledge of several commonly used Developmental Biology techniques. Students will appreciate the need for control experiments and for careful experimental manipulation in order to obtain reliable results. Analytical skills You will develop skills in experimental design to plan experiments and work together to tackle problems. Design will be modified based on the results to try to achieve desired outcomes. Group/team working You will work in teams of 2 or 3 to perform experiments. Teamwork will be required to work to a deadline. Innovation/creativity You will develop skills in experimental design to plan experiments and work together to tackle problems. Design will be modified based on the results to try to achieve desired outcomes. Leadership You will develop skills in experimental design to plan experiments and work together to tackle problems. Project management You will develop skills in experimental design to plan experiments and work together to tackle problems. Problem solving You will develop skills in experimental design to plan experiments and work together to tackle problems. Research You will develop skills in experimental design to plan experiments and work together to tackle problems. Written communication You will collate data and describe in powerpoint. You will use statistical analysis to describe data succinctly. Module 1. Dr Kathy Hentges Genetic linkage and mutation detection in human disease. During this module, students will identify a human disease gene based on linkage analysis of affected families. Upon identification, students will analyse gene sequence data to determine the nature of the mutation. Techniques will include: pedigree and genotype analysis; DNA sequence analysis; bioinformatics methods for mutation detection and functional profiling.Module 2. Prof Andreas Prokop The fruit fly Drosophila is a highly efficient and cost-effective model organism with which to explore fundamental mechanisms of biology, which then often apply to higher organisms - to a degree that mouse genes can sometimes be interchanged with those of flies; 10 Nobel laureates awarded  in "Physiology or Medicine" for work in fruit flies. During this week, you will experience how this works by understanding the idea behind a genetic screen, how to analyse mutant fly embryos and how the findings apply to higher organisms. Learned skills include immuno-histochemistry, strategies for microscopical analysis and applied classical genetics.Module 3 Dr Paul Kasher and Dr Shane Herbert Using zebrafish as a developmental model of human disease. During this practical, students will perform chemical-induction of spontaneous blood vessel rupture in the brains of zebrafish embryos, to model aspects of human haemorrhagic stroke. To investigate a genetic basis of disease, students will perform genotype:phenotype correlation analysis in zebrafish embryos derived from a genetically modified line that has a mutation in a gene associated with neurovascular instability and juvenile stroke in humans. Techniques will include: zebrafish embryo manipulation and drug administration, microscopy, histology, DNA extraction, PCR and restriction fragment polymorphism analysis.Module 4. Dr Karel Dorey and Dr Sarah Woolner Role of growth factor signalling in mesoderm induction. In this practical, Xenopus embryos will be used to assess the role of TGFβ and FGF signalling in mesoderm induction. We will analyse the effect of inhibiting TGFβ and FGF signalling using small chemical inhibitors in early Xenopus embryos and activating the TGFβ pathway in naïve animal cap cells with the ActivinβB ligand. The effects of the different treatments will be analysed at the phenotypical level and by monitoring the expression of genes specific for different tissue types by RT PCR. Techniques will include in vitro fertilisation, raising Xenopus tadpoles, the ex vivo culture of embryonic tissues, RNA extraction and RT-PCR. 0 Other 50% 3 Report 50% <ul><li>50% Full report with Introduction, Methods, Results, Discussion and References on “Zebrafish as a developmental model of human disease” - 5-page report (Arial, 10 point, 1.5 line spacing, with margins of at least 2.5 cm all around the text - References not included in the five page limit) – submission two weeks after the end of the RSM</li><li>17% Human Genetics (3 ePBLs for 7.5% during RSM - Linkage mapping 9.5% deadline 1 week after the end of the module – week 4)</li><li>17% Drosophila (Genetic pedigree of mutants – deadline 1 week after end of the module – week 5 + negative marking for mini-tasks to be completed during the RSM)</li><li>16% Xenopus (data handling exercise to do during the practical 6%, online ePBLs on RSM content 10%) </li></ul>RSM Attendance guidelinesStudents are expected to attend all scheduled RSM sessions on time (N.B. Health and safety information will be delivered at the start of practical sessions, and students who are not present at the start may be asked to leave the lab). Students who arrive late will be marked as absent for that session. Failure to attend a session (an unauthorised absence) will result in a 10% (i.e. 10 mark) penalty being applied to the overall RSM mark (i.e. a student obtaining a mark of 65% overall will instead receive a mark of 55%). .Further absences will result in further penalties (i.e. 2 absences = a penalty of 20% (as described above)). During the practical sessions, there will be many opportunities for you to get feedback from staff or demonstrators on your technical performance. The short answer questions or exercises in the practical manual are there to test your understanding and you should get feedback from staff or demonstrators on your answers. You will get feedback on your overall performance in the form of the final mark for the unit and should get feedback on the short reports for each module.
