Discovering diverse mechanisms of migration

These pathways lead to diverse cellular effects on normal processes such as growth, development and migration or, when aberrantly regulated, diseases such as cancer, diabetes and neurodegeneration ensuring the widespread application of this project.

We demonstrated that the Src inhibitor SU, identified in our screen, can be used to suppress the metastatic capacity of a highly aggressive mammary tumor cell line. The current preclinical pipeline for target-driven drug discovery involves multiple rounds of in vitro biochemical and cell-based assays followed by in vivo studies in animal models, and finally trials in humans.

In both events, cells delaminate, acquire migratory behavior, and progress through extracellular matrix to reach a distant target. Parallels can been drawn between the collective migration Discovering diverse mechanisms of migration the PLLp cells and the behavior of invasive cancer cells.

This could involve engineering mutations that allow investigation into novel activation sites within these molecules. Previous article in issue. Furthermore, there is an opportunity to investigate zinc transporter expression by immunohistochemistry in a wide range of clinical material.

The successful progression of the project should allow opportunities to progress findings towards clinical trial development. This could involve engineering mutations that allow investigation into novel activation sites within these molecules.

This process typically takes years before drugs reach the market and is expensive, limiting the number of compounds that can effectively be translated into therapeutic use.

These pathways lead to diverse cellular effects on normal processes such as growth, development and migration or, when aberrantly regulated, diseases such as cancer, diabetes and neurodegeneration ensuring the widespread application of this project. We took advantage of the transgenic reporter line cldnb: A sense of community and a sense of place measure the relation between neighboring, participation in community activity and migration.

The aim of this study is to investigate the relation between social capital and migration from rural areas in Indonesia.

Additionally, there will be use of fluorescent microscopy to image zinc and monitor changes in cellular location and cell migration in relation to resistance to anti-hormones. Via a high-throughput screening protocol, the authors identified a number of compounds, which included novel flavonoid-derivative molecules and a cluster of structurally related kinase inhibitors that interfered with primordium migration without overt toxicity in vivo.

We identified compounds that interfere with primordium migration without overt toxicity in vivo. Most of the positive in vitro results were not replicated when tested in vivo. RESULTS Screening for cell-migration inhibitors We developed a whole-organism-based chemical screening strategy to rapidly identify novel small-molecule modulators of cell migration during zebrafish PLL formation.

Demonstrating the utility of this approach, the authors confirmed, by performing orthotopic tumor implantation assays in mice, that inhibition of the Src pathway decreases tumor metastasis in vivo. In addition, others have shown that the main signaling pathways responsible for the regulation of cell mobilization are active during both development and tumor metastasis Yang and Weinberg, Methods The student will use both molecular biological and cell biological techniques, already working within the group, that complement the functional investigation of the group into the workings of the ZIP family of zinc transporters.

Yet, metastasis remains the most poorly understood component of cancer pathogenesis because this process is inherently difficult to model and study in vitro.

We also confirmed, in a mouse tumor model, that the Src inhibitor SU also specifically decreases tumor metastasis. Funding Notes This opportunity is only available to students with a scholarship to cover their funding.

In contrast, phenotype-driven screens have shown a much stronger success rate, which is why we developed an in vivo assay using transgenic zebrafish with a GFP-marked migrating posterior lateral line primordium PLLp to identify compounds that influence collective cell migration.

The PLLp is a group of migrating cells that moves dorsally along the body of the fish, depositing clusters of cells along the way that become the lateral line neuromasts Aman and Piotrowski, ; Ghysen and Dambly-Chaudiere, We identified several kinase inhibitors, flavonoid-derivatives and antioxidants that all disrupted primordium migration.

The goal of identifying cell-migration inhibitors is to find compounds that have anti-metastatic activity. This opportunity is only available to students with a scholarship to cover their funding. This project aims to substantiate a model for integrated zinc signalling in cells, confirming the exact role of different zinc transporters and relating the findings to the fundamental biological effects of cellular zinc.

Selected compounds were confirmed in their migration-blocking activity by using additional assays for cell migration.

These studies have generated thousands of candidate drugs for a variety of biological targets; however, these approaches have had very poor success rates when it came to therapeutic drugs because they generally lacked relevant whole-organism physiology.Discovering zinc signalling mechanisms to prevent breast cancer progression Zinc is essential for all living cells, yet the true extent of its role is only now emerging and is fully suggestive of a complexity and importance of that attributed to calcium.

Migrants to the United States are a diverse population. This diversity, captured in various migration theories, is overlooked in empirical applications that describe a typical narrative for an average migrant. Discovering Diverse Mechanisms of Migration: The Mexico–US Stream – Scholars have identified diverse mechanisms that lead individuals to mi- grate.

these mechanisms are analyzed in various migration theories devel- oped in multiple disciplines. in neoclassical economics. At ARVO’s annual meeting held in late April, Hartnett will present the Weisenfeld lecture, entitled “Discovering Mechanisms in the Changing and Diverse Pathology of ROP.”.
