Estudio de la función de los factores de transcripción PBX en la diferenciación a neurona dopaminérgica del bulbo olfatorio de ratón
2017
[EN] Dopamine signalling regulates a variety of complex behaviours and defects in dopaminergic neuron function or survival result in severe human pathologies such as Parkinson´s disease. All dopaminergic neurons are characterized by the expression of a battery of genes that code for a set of proteins required for the synthesis, release and re-uptake of dopamine and all together are called the DA pathway genes. Therefore, understanding how this set of genes are transcriptionally activated in a coordinated manner is the first step to discover the clues of dopaminergic terminal differentiation. The dopamine pathway genes are highly conserved throughout evolution. Studies in the nematode C.eleg…
Computational methodologies applied to Protein-Protein Interactions for molecular insights in Medicinal Chemistry
2021
In living systems, proteins usually team up into “molecular machinery” implementing several protein-to-protein physical contacts – or protein-protein interactions (PPIs) – to exert biological effects at both cellular and systems levels. Deregulations of protein-protein contacts have been associated with a huge number of diseases in a wide range of medical areas, such as oncology, cancer immunotherapy, infectious diseases, neurological disorders, heart failure, inflammation and oxidative stress. PPIs are very complex and usually characterised by specific shape, size and complementarity. The protein interfaces are generally large, broad and shallow, and frequently protein-protein contacts are…

The abrogation of the HOXB7/PBX2 complex induces apoptosis in melanoma through the miR-221&222-c-FOS pathway.
2013
Cutaneous melanoma is the fastest increasing cancer worldwide. Although several molecular abnormalities have been associated with melanoma progression, the underlying mechanisms are still largely unknown and few targeted therapies are under evaluation. Here we show that the HOXB7/PBX2 dimer acts as a positive transcriptional regulator of the oncogenic microRNA-221 and -222. In addition, demonstrating c-FOS as a direct target of miR-221&222, we identify a HOXB7/PBX2→miR-221&222 →c-FOS regulatory link, whereby the abrogation of functional HOXB7/PBX2 dimers leads to reduced miR-221&222 transcription and elevated c-FOS expression with consequent cell death. Taking advantage of the treatment wit…
