Research

Each cell in our body contains the same genetic information, yet this information is read out in diverse manners, allowing different cell types to acquire distinct characteristics. Importantly, the decoding of genetic information is often corrupted in cancer, resulting in undesired characteristics, such as unrestricted proliferation and invasion of malignant cells into other tissues and organs.

The decoding of genetic information occurs sequentially from DNA, via messenger-RNA (mRNA), to proteins, the final and functional products of most genes. My lab is particularly interested in understanding how synthesis of cellular proteins from mRNA is dysregulated in cancer cells through the action of an important group of proteins known as RNA Binding Proteins (RBPs).

Using cutting-edge quantitative proteomics, RNA-seq, and bioinformatics methodologies, along with a variety of cell based and biochemical assays, we study how RBPs regulate RNA in time and space, and how this regulation is altered during cancer progression.

Currently, the lab is focused on four projects:

• The role of mRNA localisation in controlling protein synthesis in normal and malignant cells.
• How ribosome biogenesis is enhanced during malignancy via specific RBPs.
• How oncogenes trigger malignancy by dysregulating the RNA binding activity of specific RBPs.
• How dysregulation of protein synthesis affects antigen presentation and the immune profile of cancer cells.

Ultimately, our goal is to understand how various aspects of cancer progression are mediated by dysregulation of RBPs, in hope of revealing novel therapeutic targets that can be exploited to tackle malignancy.
