The human Wnt signaling pathway contains 57 genes communicating among themselves by 70 experimentally established associations, as given in the KEGG/PATHWAY database. It is responsible for a variety of crucial biological functions such as regulation of cell fate determination, proliferation, differentiation, migration, and apoptosis. Abnormal behavior of its members causes numerous types of human cancers, dramatic changes in bone mass density that lead to diseases such as osteoporosis-pseudo-glioma syndrome, Van-Buchem disease, skeletal malformation, autosomal dominant sclerosteosis, and osteoporosis type I syndromes. So far, single genes have been investigated for their disease-causing properties, and single diseases have been traced backwards to discover foul-play of the system pathways. Differential expression of the whole genome has been mapped by microarray. But how all the genes involved in a pathway affect each other in single/multiple disease state(s) and whether the presence of one disease state makes a person prone to another kind of disease(s) (i.e., co-morbidity among diseases associated with a certain important biological pathway) is still unknown. We have developed a human Wnt signaling pathway diseasome and analyzed it for finding answers to such questions. Data used in constructing the diseasome can be downloaded from the publicly accessible webserver http://www.isical.ac.in/-rajat/diseasome/index.php.

Proteases, including lysosomal cathepsins, are functionally involved in many processes in cancer progression from its initiation to invasion and metastatic spread. Only recently, cathepsin K (CatK), the cysteine protease originally reported as a collagenolytic protease produced by osteoclasts, appeared to be overexpressed as well in various types of cancers. In this review, the physiological functions of CatK are presented and compared to its potential role in pathobiolology of processes associated with tumour growth, invasion and metastasis of cancer cells and their interactions with the tumour microenvironment. CatK activity is either indirectly affecting signalling pathways, or directly degrading extracellular matrix (ECM) proteins, for example in bone metastases. Recently, CatK was also found in glioma, possibly regulating cancer stem-like cell mobilisation and modulating recently found physiological CatK substrates, including chemokines and growth factors. Moreover, CatK may be useful in differential diagnosis and may have prognostic value. Finally, the application of CatK inhibitors, which are already in clinical trials for treatment of osteoporosis, has a potential to attenuate cancer aggressiveness.
