Biosketch

Hector G. Palmer and his Stem Cells & Cancer Group are studying the mechanisms that permit tumors to escape from effective treatments and progress to advanced stages, when patients’ lives are at risk.

His team uses multi-omic approaches for revealing unexpected alterations related with tumor phenotypes. The group also pairs gene editing (CRISPR/Cas) with classical signalling biochemistry in cancer cell lines as well as genetically modified mice, patient-derived organoids and xenografts (PDX) to study the functional relevance of these newly identified alterations in patients’ response to therapies.

The group is also part of a global multidisciplinary task force that includes oncologists, surgeons, radiologists and nurses. This strong collaboration means that laboratory results have a rapid clinical interpretation and translation to the bedside.

Main research lines include:

Tumor cell dormancy

We study the intriguing biology of cancer cell dormancy that is responsible for chemoresistance, formation of minimal residual disease and relapse of patients. The team discovered a core epigenetic network governing dormancy of tumor cells (J Clin Invest. 2018), and is now studying the function of TET2, DPPA3 and other epigenetic factors governing dormancy in further depth. Importantly, we are rapidly progressing in developing drugs that modulate dormancy drivers including TET2 and defining novel biomarkers to detect chemo-resistant dormant tumor cells (DTC).

Response to target-directed drugs

Our group works in close collaboration with oncologists and pharmaceutical companies to identify molecular mechanisms responsible for the sensitivity or resistance to drugs blocking Wnt/beta-catenin, Notch, PI3K/AKT, EGFR/LGR5 or BRAF/MEK/ERK oncogenic signals (Nat Med. 2012; Clin Can Res. 2014; Clin Can Res. 2019). Based on our discoveries we are designing new pre-screening tests for a genetic-guided enrolment of patients in clinical trials. Crucially, our findings are helping to define new rational drug combinations to treat cancer patients with progressive disease.

Advanced pre-clinical models of cancer

We are expanding and characterizing our PDX collections (CRC, neuroendocrine, hepatic tumors and peritoneal pseudomyxoma), and improving their potential to evaluate drug efficacy and metastasis by orthotopic injection and live imaging (TC, PET and Echography).

We are developing ambitious projects through the EuroPDX Consortium, a collaboration that VHIO co-founded incorporating the main reference groups working with PDX in Europe.

STRATEGIC GOALS

  • Understanding Tumor Dormancy Studying the role of epigenetic factors ruling dormancy in chemoresistance, minimal residual disease, relapse, dissemination and metastasis.
  • ONIRIA – modulating cell dormancy to fight cancer Developing small drugs modulators of cancer cell dormancy to block cancer progression.
  • Matching targeted therapies Revealing the mechanisms of response to drugs targeting EGFR, BRAF, MEK, ERK, LGR5, Wnt or PARP.
  • Refining advanced cancer models Expanding our collection of PDXs and developing new orthotopic models and live imaging techniques.

 


HIGHLIGHTS

  • Cancer cell dormancy We have revealed key epigenetic factors ruling cancer cell dormancy, hypoxia, chemoresistance and tumor recurrence and developed effective small drugs targeting some of them.
  • Matched therapies Our group has described relevant determinants of response to BRAF and Notch inhibitors, and demonstrated the efficacy of new rational drug combinations and evaluated the minimal residual disease of RET fused tumors.
  • Advanced cancer models We have generated and refined new cancer models of colorectal cancer in collaboration with several European funded networks.
