IMB Advantage

Date/Time: Monday 27th March 2017 12:30

Location: Large Seminar Room (3.142)

Title of talk: Introduction to analysis of high-throughput sequencing data
Speaker's name: Dr Igor Makunin
Speaker's organisation: IMB
Talk abstract: The seminar provides an overview of concepts, tools and data types used in analysis of high-throughput sequencing data, such as reference\r\ngenomes and genome indices, aligners and genome browsers, alignment and gene annotation formats. The participants will be introduced to a local\r\nGalaxy-qld server, a web-based platform for analysis of high-throughput sequencing data.\r\nThe seminar is aimed for people new to genomics and nextGen sequencing and may be useful for researchers across all areas of IMB. It does not require IT knowledge or programming skills. The seminar is designed as a theoretical introduction to planned Galaxy workshops.

Location: Lvl 2 Seminar Room, Centre for Advanced Imaging Bld57

Title of talk: A comparative approach to cancer imaging: What can we learn?
Speaker's name: Amy K. LeBlanc, DVM Diplomate ACVIM (Oncology)
Speaker's organisation: Director, Comparative Oncology Program Center for Cancer Research, National Cancer Institute National Institutes of Health
Talk abstract: Comparative oncology research is gaining traction as a method for streamlining the drug discovery and development strategies currently in place worldwide. This approach employs the tumor-bearing pet dog as a relevant and complementary model alongside the traditional laboratory species to advance our collective knowledge of cancer biology and drug development. To complement ongoing efforts in this field, we propose expansion of comparative cancer imaging as a key component to drug discovery and development. Molecular imaging techniques allow for detection of disease-specific signals that provide individualized data to aid in patient selection, response to therapy, and prognostication. In this seminar, I will highlight comparative oncology studies that have employ molecular imaging techniques, demonstrating the value of spontaneous canine cancers as a research tool in drug and imaging agent development.

QAaFI Science Seminar Series

Date/Time: Tuesday 28th March 2017 12:00

Location: Large Seminar Room (3.142), Level 3 Qld Bioscience Precinct Building 80, St Lucia

Title of talk: Primary plant cell walls as cellulose hydrogels
Speaker's name: Professor Mike Gidley
Speaker's organisation: QAAFi
Talk abstract: The structure and material properties of growing and fleshy plant tissues are determined by their (primary) cell walls. The biological requirement in growing tissues for cell walls to combine structural strength with flexibility and extensibility is met through a network of cellulose fibres in a hydrogel form that is modified by the presence of other polysaccharides. From direct measurement on isolated plant cell walls and using a model bacterial cellulose hydrogel system, the molecular rules governing the association of non-cellulosic polysaccharides with cellulose fibres have been deduced. The effects of various features of cell wall hydrogels on the characteristic material properties under small deformation, compression and extension have been characterized and rationalized. Consequences for plant material properties and plant food behaviour in the digestive tract will be discussed.

SCMB Chemistry Seminar

Location: AIBN Seminar Room

Title of talk: Some New Synthetic Applications of \
Speaker's name: Dr. (Thanh) Vinh Nguyen
Speaker's organisation: UNSW
Talk abstract: Abstract: \r\nCycloheptatrienylium (tropylium) ions and N-heterocyclic olefins (NHOs) are no ordinary alkenes! Tropylium ions have planar seven-membered ring structures with (4n+2) = 6p electrons in fully conjugated systems, allowing the positive charge to delocalise across the rings. They fulfill Hückel's rule for aromaticity and hence possess extraordinary stability for charged cyclopolyenes. NHOs are the alkylidene derivatives of N-heterocycles with highly polarized exocyclic C-C double bonds, making the α-carbons very electron-rich and therefore rendering them reactive nucleophilic centers. Our recent studies on the novel applications of tropylium salts and NHOs as versatile organocatalysts and stoichiometric reagents for several important chemical transformations will be discussed in this seminar.

Chemistry & Structural Biology Seminar Series

Date/Time: Thursday 30th March 2017 12:30

Location: Seminar Room 3.142

Title of talk: Breast development, function and signal transduction
Speaker's name: Dr Felicity Davies
Speaker's organisation: School of Pharmacy, The University of Queensland
Talk abstract: The mammary gland undergoes cycles of growth, death and regeneration throughout reproductive life, a process that requires long-lived adult mammary stem cells. Whilst recent genetic fate-mapping studies, using promoters specific for either the luminal or basal epithelial cell lineages, have provided valuable insights into the mammary epithelial hierarchy, controversy still remains as to the true differentiation potential of adult mammary stem cells and whether there are distinct populations. As presumptive targets for transformation in breast cancer, the identity of adult mammary stem cells and the origin of luminal and basal cell lineages, have important implications for breast cancer. Here, I will discuss recent results from neutral, single cell lineage-tracing studies which revealed the immense capacity of a single, unipotent mammary stem cell to contribute to pubertal and gestational breast development. I will also discuss how the intracellular calcium signal exquisitely controls oxytocin-mediated milk expulsion during lactation.
