A role for Cited2, Transforming Growth Factor-beta and matrix metaloproteinases in trophoblast invasion and placenta formation. The placenta is essential for the growth and development of the fetus, and if it fails to form correctly during pregnancy, it can have dramatic effects that can result death in utero, or adult onset diseases. Our research aims to understand how one protein functions in placenta formation. We will also investigate how this protein works at the molecular level in a proces ....A role for Cited2, Transforming Growth Factor-beta and matrix metaloproteinases in trophoblast invasion and placenta formation. The placenta is essential for the growth and development of the fetus, and if it fails to form correctly during pregnancy, it can have dramatic effects that can result death in utero, or adult onset diseases. Our research aims to understand how one protein functions in placenta formation. We will also investigate how this protein works at the molecular level in a process that enables single cells to respond to molecules sent from a distance by other cells (TGF-beta signalling). This process is also very important for a host of other biological processes relevant to human health, including cancer.Read moreRead less
Specification and evolution of vertebrate appendicular muscle. Previously we have determined that two different developmental mechanisms are utilised to make the muscles present within the fins and limbs of distinct vertebrate species. This proposal is concerned with determining the morphogenetic, evolutionary and molecular basis for these two different developmental modes. To do this we will to extend our observations more widely to examine muscle formation in both the paired fins in a phyloge ....Specification and evolution of vertebrate appendicular muscle. Previously we have determined that two different developmental mechanisms are utilised to make the muscles present within the fins and limbs of distinct vertebrate species. This proposal is concerned with determining the morphogenetic, evolutionary and molecular basis for these two different developmental modes. To do this we will to extend our observations more widely to examine muscle formation in both the paired fins in a phylogenetically diverse context. We further hope to determine the underlying genetic basis for these different morphologies by developing techniques to examine their formation in a number of embryonic contexts.Read moreRead less
Defining in molecular terms cis-inhibition as a means to inhibit Notch signaling. Normal development of a baby and our health after birth is dependent on how our cells behave. Signals move between cells and within them to tell them what to do. Proteins interacting with other proteins mostly transmit these signals. This research focuses on a protein named Notch and the signals that it transmits. Notch functions in normal processes, such as blood vessel formation; but abnormal signaling causes and ....Defining in molecular terms cis-inhibition as a means to inhibit Notch signaling. Normal development of a baby and our health after birth is dependent on how our cells behave. Signals move between cells and within them to tell them what to do. Proteins interacting with other proteins mostly transmit these signals. This research focuses on a protein named Notch and the signals that it transmits. Notch functions in normal processes, such as blood vessel formation; but abnormal signaling causes and/or contributes to pathological situations such as degenerative disease and cancer. We are working to understand how the Notch signal is made and how to control it when it is abnormal. This will allow new medications to be developed to help people who have cancer and other Notch-related illnessesRead moreRead less

Exploration of a mechanistic link between eukaryotic transcription and translation. Gene transcription is functionally coupled to other aspects of eukaryotic mRNA metabolism, emphasizing a need for integrated approaches to analyse the gene expression pathway. We have shown in previous work that yeast cells, when responding to external stimuli, show a tight correlation between changes in the transcriptome composition and homodirectional alterations in the translation state of mRNAs. This phenomen ....Exploration of a mechanistic link between eukaryotic transcription and translation. Gene transcription is functionally coupled to other aspects of eukaryotic mRNA metabolism, emphasizing a need for integrated approaches to analyse the gene expression pathway. We have shown in previous work that yeast cells, when responding to external stimuli, show a tight correlation between changes in the transcriptome composition and homodirectional alterations in the translation state of mRNAs. This phenomenon of ?potentiation? may serve to amplify signal-induced changes in the transcriptome at the translational level. This project will begin to unravel the molecular mechanisms underlying potentiation using experiments designed to distinguish between transcription- and translation-driven mechanisms.Read moreRead less
