Research Direction:

Cancer cells possess characters similar to healthy 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 in colorectal carcinoma (CRC) and identify essential 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-miR-146a-Numb circuits were demonstrated to maintain Nanog/OCT4 expression for maintaining tumor niches 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. Dr. Hwang’s studies reveal the presence of a complex Snail-induced interactome in CRC-CSCs, proving potential drug targets for advanced CRC patients.

Research Highlights:

  1. Wnt-driven RAB27B activation mediates the CSC-CRC cell interaction through exosomal miR-146a-5p.
  2. CSCs elicit the pattern recognition response in host neutrophils through exosomal non-coding RNAs.
  3. Lymphotoxin-β dictates the Cetuximab resistance in head-and-neck cancer.
  4. The asymmetric-to symmetric (ACD-SCD) division mode of CSC maintains stem-like population.
  5. Snail-IL8 axis introduces cancer stemness in non-CSC cells and sustains the self-renewal of CSCs
