Read more Gastrulation, the early stage of embryonic development in which the organs are starting to form, is an elusive stage, which is hard to investigate because its access in mammals is limited. In this talk I will describe how our lab was able to grow mouse embryos outside the uterus, and how our work on stem cells has ultimately enabled us to grow synthetic embryos, generated from stem cells without egg and sperm, thus allowing us a window to mammalian gastrulation.

Read more Molecules that can undergo self-assembly are of great interest for the development of new materials, sensors, biolabels…. In some cases the assembly can lead to an enhancement of the emission, a change in the luminescence energy and even to unexpected biological phenomena. The talk will illustrate some of the recent results on the self-assembly of platinum complexes and their evolution in solution[1]. Some water soluble compounds where studied to follow the self-assembly even in vivo and the resulting reactivity/toxicity of such species. We employed transparent polyps, Hydra vulgaris and an extraordinary phenomenon was detected with one of the complex that showed a clear effect on pluripotent stem cell proliferation, especially at low doses. The stabilization of transient species, formed in the assembly process can be achieved using cage type structures can lead to their stabilization or even existence in solution, in a condition out of equilibrium. We recently demonstrated[2] that it is possible to entrap intermediate states of luminescent assemblies and prevent their thermodynamic evolution towards the equilibrium state. Such cages are also the carriers for important drugs do to their destruction inside cells. Their biodistribution is quite unique and they are able to escape macrophages uptake.[3] References [1] A.

Read more Using mammalian skin as a model, Prof. Elaine Fuchs studies the remarkable properties of tissue stem cells to replenish dying cells and repair wounds, and how the cells know which tasks to perform and when. She explores how stem cells sense and communicate with other cells in their environment. Aiming at advancing therapeutics, she dissects how communication networks malfunction in inflammation, aging, and cancers.

    Organizer: Department of Biomolecular Sciences
    Abstract: Bromodomain-containing protein 4 (BRD4) is an epigenetic regulator and transcrip ... Read more Bromodomain-containing protein 4 (BRD4) is an epigenetic regulator and transcription cofactor whose phosphorylation by casein kinase II (CK2) and dephosphorylation by protein phosphatase 2A (PP2A) modulates its function in gene-specific targeting and recruitment of transcriptional regulators and chromatin modifiers. BRD4 has emerged as an important cancer therapeutic target due to widely available small compound inhibitors, such as JQ1 and I-BET, targeting the bromodomain and extra-terminal (BET) family members. Besides transcriptional regulation, BRD4 also plays crucial roles in regulating diverse cellular processes, including cell cycle progression, DNA damage response, chromatin structure maintenance, stem cell reprogramming, cell lineage differentiation, and viral latency and reactivation. While BET inhibitors and degraders show promising anticancer effects, issues related to drug resistance upon prolonged treatment remain a challenge in BET-targeted therapeutics development. Recently, we identified specific small compound inhibitors targeting phosphorylation-dependent BRD4 interaction with distinct transcription/replication components and DNA damage response (DDR) factors, including p53, c-Myc, AP-1, and cancer-associated human papillomavirus E2 proteins. Some of these compounds effectively block cancer cell growth and migration and specifically inhibit p53 interaction with BRD4. These new types of protein-protein interaction (PPI) inhibitors highlight molecular action distinct from the widely used BET bromodomain inhibitors.
