Patologia Molecular Translacional

El nostre grup té com a objectiu desvelar els mecanismes moleculars de la progressió i les metàstasis del càncer per a identificar nous marcadors diagnòstics, pronòstics, així com noves dianes terapèutiques. Gràcies al profund coneixement de les bases moleculars tumorals del grup d’investigació, així com a la disponibilitat de mostres tumorals humanes, desenvolupem diferents línies d’investigació centrades en el següent: 

  • Conèixer els mecanismes moleculars subjacents a la cooperació clonal i la comunicació intercel·lular implicades en l’heterogeneïtat tumoral.
  • Descriure el paper de les mitogen-activated protein kinase-interacting kinases (MNK) en el desenvolupament de resistències davant de l'estrès cel·lular.
  • Aprofundir en el paper de la integrina ß-3 (ITGB3) en la comunicació intercel·lular mitjançant vesícules extracel·lulars en models de metàstasi (Santiago Ramón i Cajal).
  • Estudiar les comunicacions cèl·lula-cèl·lula a través d’unions intercel·lulars comunicants (gap junctions) i/o protrusions intercel·lulars en el càncer (Trond Aasen).
  • Estudiar la transformació oncogènica dels neurofibromes plexiformes (Cleofe Romagosa).

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.

Identification of molecular targets associated with tumor progression and therapy resistance in colorectal carcinoma.

Studying in colorectal cancer mechanisms of action of the central signal transduction pathways, identify potential molecular alterations that can be used as therapeutic targets and characterize the degree of genetic inestability.

Involvement of the human Hepatitis A Viral Receptor (hHAVcr-1) in renal cancer development and progression. Value as a diagnostic and prognostic biomarker in renal carcinomas

We have postulated that hHAVcr-1 might constitute an important biomarker for early detection of ccRCC and could also be used as a target for therapy of kidney carcinomas, since immunotoxins directed against the monkey homologue of hHAVcr-1 could kill kidney cells.


Specific aims are focused to: i) determine the diagnostic and prognostic potential of hHAVcr-1 expression in renal cell carcinomas, by correlating hHAVcr-1 levels in archive, fresh surgical and TMA tissues  with tumor anatomo-pathological characteristics and patients outcome and, ii) determine the function of hHAVcr-1, which remains elusive, in development and progression of kidney carcinomas, using ccRCC derived cell lines with silenced or overexpressed hHAVcr-1. Tumors overexpressing or defective in hHAVcr-1 will be compared with controls, in relation to their behavior and anatomo-pathological characteristics. Differences are being correlated with proteomic and gene expression profiles obtained on each case. Differential expression pathways and target molecules correlating with absence/presence of hHAVcr-1 shall be identified. New strategies for diagnosis, prognosis and treatment of ccRCC must be further developed.

Long-term mast cell stabilization downregulates mucosal microinflammation in the jejunum of diarrhea-prone irritable bowel syndrome (IBS)

Study of the effect of mast-cell stabilization on mucosal inflammation and the clinical response. Inmunohistochemistry analysis of microinflammation (mast cells, intraepithelial lymphocytes and eosinophils) in Irritable Bowel Syndome (IBS) Biological inflammation was evaluated in pooled biopsies by quantitative real time PCR to analyze the expression of preselected genes implicated in innate inmunity (Toll-like receptors (TLR) and defensins (DEF)), mast cell activation and growth and neuronal regulation.. Mucosal eosinophils show restrained activation in the yeyunum od diarrhea –prone irritable bowel sindrome patiens

Pharmacological stabilization of mucosal mast cells effectively reduces pro-inflammatory gene expression profiles in the jejunal mucosa of D-IBS patients and concomitantly improves clinical manifestations.
