Research interests:

My work involves using bioinformatics approaches to integrate data generated from multi-omics (including genomics, proteomics, transcriptomics, metablomics, etc.) techniques to study parasite-host interaction and to develop visualization methods that makes computational biology accessible to research scientists with no programming experience.

Recent Research Project: The role of microproteins on the regulation of iron stress response in Trichomonas vaginalis

Microprotein (MP) is defined as a protein composed of less than 100 amino acids. Accumulated experimental data showed that microproteins play important regulatory roles in various biological processes, including tumor progression, stress response, and signaling transduction. However, microprotein has been under-studied because classical genome annotation methods do not consider open reading frames (ORF) less than 100 amino acids as putative genes. Recent developments in new-generation sequencing techniques allowed us to identify novel MPs and obtain a more comprehensive view of these novel MP's expression profiles. Up to date, MP research had not been explored in any protozoan. Our research will use Trichomonas vaginals as a model system to identify and characterize the putative functional roles of MP under iron stress. T. vaginalis is the causing agent of the most common sexually transmitted infection (STI) of nonviral origin in humans trichomoniasis. Iron is an essential element for the survival of T. vaginalis, which sustains hydrogenosomal quality, energy metabolism, and redox homeostasis.

Our preliminary study based on an integrated genome-wide ORF screening, transcriptomic and exosome proteomic data analysis showed that MP did express in the T. vaginalis transcriptome and proteome. These exciting results prompted us to initiate studies on unexplored field. We aimed to investigate the functional roles of iron-dependent microproteins in T. vaginalis and to establish an experimental and analytical platform for studying microproteins.
