Translational Molecular Pathology

Our group aims to unravel the molecular mechanisms of cancer progression and metastasis to identify new diagnostic, prognostic and therapeutic targets in cancer. By combining the knowledge and availability of human tumors in the Pathology department with the expertise of the basic molecular cell biology research group, we focus on:

  • Understanding: the molecular mechanisms underlying clonal cooperation and intercellular communication in heterogeneous tumors.
  • The role of MNK kinases in cellular stress resistance.
  • The role of ITGB3 in intercellular communication via extracellular vesicles in cancer metastasis (Santiago Ramon y Cajal).
  • The role of direct cell-cell communication via gap junctions and intercellular protrusions in cancer (Trond Aasen)
  • The malignant transition of Plexiform Neurofibromas (Cleofe Romagosa).

Expression analysis and functional elucidation of connexins and pannexins in relation to human cancer progression and malignancy.

Connexins and pannexins are structural units of gap junctions permitting direct intercellular communication. Deregulation of gap junctions is a frequent feature of carcinogenesis. We are characterizing the expression level of a variety of connexins and pannexins in primary and metastatic human tumours. In vitro we are studying how these proteins affect features related to the degree of malignancy such as migration, invasion and resistance to hypoxia.  In connexin-deficient cell lines we are over-expressing specific wild-type or truncated forms of connexins and pannexins using retroviral constructs recently generated. In cell lines expressing high levels of specific connexins, we knockdown the expression levels using established lentiviral shRNA strategies. We aim to correlate connexin expression and cell communication with malignancy using a variety of well characterized assays with particular focus on colony formation, migration, invasion, epithelial-to-mesenchymal transition, changes in tumour stem cell populations, and hypoxia and drug resistance. The aim of the study is to: 1) Identify any significant correlation between the expression of various gap junction proteins and the malignancy, prognosis, chemo-resistance and overall survival in a variety of cancers 2) Gain mechanistic insight and identify direct functional roles of connexins and pannexins during tumour progression.

Genomic transcriptional profile analysis in proliferative inflammatory atrophy (PIA) as a possible precursor of human prostate cancer

To analyse transcriptional profiles of normal, PIA (proliferative inflammatory atrophy), PIN (prostatic intraepithelial neoplasia)  and tumoral prostate using microarrays of selected tumoral tissue of prostatectomy specimens, in order to characterize  gene expression modifications in prostate cancer versus PIN and PIA.

To analyse the biological response on tumoral / non-tumoral and co-culture them with monocytes in order to study transcriptional profile changes.

From all the data obtained, overexpressed / underexpressed genes are being identified and      validated. Stromal and inflammatory genes also will be explored for their potential use as early markers for prostatic cancer and their ability to identify PIA as a precursor lesion.

The grants promote new therapeutic strategies and diagnostic tools in highly complex tumors such as glioblastoma, triple-negative breast cancer, and endometrial cancer.

The Department of Health of the Generalitat de Catalunya grants subsidies for carrying out validation tests on innovative projects in the field of health that are in the early stages of development.

The meeting was an opportunity to get to know projects from both institutions and to promote interaction between professionals.
