ELF3: A Key Player in Blocking Epithelial to Mesenchymal Transition

Work done in the lab of Dr Mohit Kumar Jolly at the Centre for Biosystems Science and Engineering, IISc.

About author

Subbalakshmi is a graduate student pursuing her PhD in Bioengineering at the Centre for BioSystems Science and Engineering, Indian Institute of Science, Bengaluru. She works with Dr. Mohit Kumar Jolly to understand the processes involved in cellular transitions during cancer progression. She is interested in understanding cellular plasticity and factors promoting cellular plasticity during cancer metastasis.

Interview

How would you explain your research outcomes to the non-scientific community?

Metastasis of cancer cells and their resistance to therapy have been a major challenge, and which is why cancer is one of the leading causes of death due to non-communicable diseases. And one of the reasons for this is the ability of the cancer cells to undergo the process of epithelial mesenchymal plasticity (EMP), where they can reversibly switch between the epithelial, mesenchymal, and hybrid E/M phenotypes. And in our research we try to identify molecular factors that help the cancer cells undergo the process of EMP and also understand what factors stabilise the cells in a particular phenotype along the EMP spectrum. In this direction, the molecule E74-like factor 3 (ELF3) was identified as a factor that maintained the cell’s epithelial phenotype. Also, it inhibited the cells from undergoing the process of epithelial to mesenchymal transition (EMT). It was also observed that when the cells underwent the process of EMT there was a reduction in the levels of ELF3. This was seen both in bulk and single cell data. All these observations indicate that ELF3 is a transcription factor that inhibits the cells from undergoing EMT and stabilise them in the epithelial phenotype.

How do these findings contribute to your research area?

Identifying molecular factors that stabilise the cancer cells in a particular phenotype along the EMP axis will help in the design of effective therapeutic strategies for cancer treatments. This can help us come up with targeted therapies to combat cancer cell metastasis and therapy resistance, which have been the major roadblocks when it comes to cancer treatment.

What was the exciting moment during your research?

The most exciting part of the research was when we observed that the results we obtained using modelling approaches matched the results from patient data.

What do you hope to do next?

In future, I plan to combine multiple axes of metastasis and determine their inter-dependencies.

Where do you seek scientific inspiration from?

I got inspired to do science by observing the everyday things around me. I started to ask questions and wanted to understand them. As I progressed academically, I got fascinated by the elusiveness of cancer. I wanted to understand why it was difficult to treat cancer. On this journey I joined the lab of Dr. Jolly. He has been the one who further inspired me to continue my journey to understand cancer, even if that understanding was only a drop of water in the vast ocean of oncology.

How do you intend to help Indian science improve?

After my post-doctoral studies, I plan on returning to India and continuing my work here to aid clinicians in better understanding and treating cancer.
