Research Interest

Research Interests

  1. Targeted Therapy-Identification of hub regulators in therapeutic-resistant cells for developing targeted therapy.
  2. Tumor Microenvironments-Investigation of systemic and localized tumor-host interactions during cancer progression.
  3. Early Cancer Detection-Developing diagnostic and prognostic biomarkers for examining oncogenesis.
 

Research Direction:

Cancer cells possess characters similar to normal stem cells, and the degree of cell dedifferentiation is correlated with poor prognosis. Given our rudimentary knowledge toward mechanisms governing stem cell expansion in bulky tumors, we set out to evaluate stem-like cell isolation approaches of colorectal carcinoma (CRC) and identify key genes regulating CRC stemness. We isolated cancerous stem cell populations as colonospheres (sphere-derived cancer stem cells, SDCSCs) from primary CRC tissues and cell lines for characterization in vitro and in vivo. Microarray analysis and next-generation sequencing of the colonospheres were used to elucidate their transcriptome and miRNome for exploring their enriched biological activities. We found expanded colonospheres fulfilling the cancer stem cell criteria were enriched with CD44(+)/CD166(+) subpopulations, and had undergone epithelial-mesenchymal transition (EMT) with Snail being the predominant regulator. The Snail-IL8 signal axis and Snail-miRNA-146a-Numb circuits were demonstrated to maintain Nanog/OCT4 expression for orchestrating tumor microenvironment and Wnt signal cassettes for symmetric stem cell division, respectively. In colorectal cancer patients, Snail and IL8 were coexpressed with the stem cell marker CD44, but not with CD133 or CD24, in CRC tissues and the SnailHighNumbLow profile was correlated with Cetuximab resistance and a poorer prognosis. Our studies reveal the presence of a complex Snail-induced interactome in CRC-CSCs, proving potential drug targets for advanced CRC patients. We now focusing on tumor microenvironment and aim to characterize CSC niches by elucidating tumor-host interaction (including host endothelial cells, immune cells fibroblasts).

Ongoing project

  1. Identify the hub regulators of cancer stem cells for developing targeted therapy.
  2. Interrogate the central effectors governing tumor-host interactions.
  3. Identify diagnostic and prognostic biomarkers to monitor cancer progression.
