Regulation of hematopoietic stem cells commitment by JNK signalling pathway

Ziel

The Hematopoietic Stem Cells (HSCs) can be used as an alternative to bone marrow transplantation in the treatment of leukemia, lymphoma, certain types of anemia, and inherited disorders of immunity and metabolism. Thus it is desirable to unveil all the molecular mechanism underlying the gene reprogramming of stem cells in self-renewal and differentiation processes. Recent evidence suggests that signalling pathways classically involved in embryonic development - such as the WNT signalling pathway - plays an important role in regulating stem cells self-renewal.

In this sense, it has recently demonstrated that canonical and non-canonical Wnt signalling are connected. It has been shown that JNK and WNT signalling converge by interaction of phosphorylated c-Jun w ith TCF4. Whether the JNK pathway and c-Jun also play a role in other biological functions of Wnt signaling, like the maintenance of stem cell fate, is not known. The role of the non-canonical JNK/c-Jun pathway in HSCs will be analysed in this proposal. Th is interdisciplinary project that requires the combinatorial use of approaches from classical biochemistry, immunology, molecular biology, proteomics and cell biology, combines the latest methods in respective fields and will contribute to decipher the signals mediating the interaction between JNK/c-Jun and Wnt pathways in HSCs. The obtained results will not only broaden our academic understanding of the JNK/c-Jun and Wnt pathway, but will also provide an opportunity to define novel strategies to develop s tem cell based therapies.
