The present invention relates to a method for predicting neurodegenerative decline and / or its severity for a patient, especially of cognitive impairment (CI). Strokes and Parkinson's disease are frequently associated with occurrence of long-term cognitive impairment or dementia with still incompletely resolved mechanisms. The discovery of diagnostic and predictive biomarkers thus remains a major challenge. The method of the invention uses radiomics corresponding to texture features extracted from a plurality of previously-acquired medical brain images and correlated with previously-acquired clinical and / or biological data. A classifier is trained beforehand for learning these radiomics, and then operated on radiomics computed from at least one brain image of a patient to generate a score representative of its risks of neurodegenerative decline. By applying this method on a cohort of 160 MCI and non-MCI patients, the inventors show that MCI patients could be early predicted with a mean accuracy of 88%. In the same way, the method was able to discriminate very early stages of cognitive decline in a Parkinson's disease population of 100 patients.

A method of predicting response to treatment with inhibitors of EGFR and SRC by screening for status of key biomarkers such as EGFR. Dasatinib is a drug that can inhibit a group of proteins called SRC proteins. In addition, other experiments have suggested that other important signaling proteins are affected by dasatinib. Early phase trials of dasatinib are ongoing in cancer patients. It will be important to determine which patients receive a clinical benefit of dasatinib. Predetermination of treatment benefit can be performed by assessing biomarkers in patients tumors prior to treatment with dasatinib or other inhibitors of EGFR and SRC. Patients that have positive biomarkers for treatment could then be treated with higher confidence of benefit while those not possessing these predictive biomarkers would avoid ineffective and potentially toxic therapy. Additionally, treatment can be tailored according to predetermined sensitivity by evaluating indicated biomarkers correlating with sensitivity to one or more agents.

The invention discloses a predictive biomarker for human colorectal cancer or human colorectal cancer metastasis. The predictive biomarker comprises Ube2v1 protein. Based on the constructed colorectal cell strain with Ube2v1 over-expressed stably, the naked mouse experimental result shows that Ube2v1 can promote the growth and metastasis of tumor. Ube2v1 without functions is bonded to Ube2N for degrading histone deacetylase Sirt1, so that the deacetylation effect of Sirt1 for the H4K16 site of the histone is weakened, and the metastasis of colorectal cancer is promoted. The NSC697923 compound is added in the colorectal cancer cells, and the degradation effect of Ube2v1 for the histone deacetylase Sirt1 is obviously weakened. The result shows that Ube2v1 can be taken as the marker for the generation and metastasis of colorectal cancer, and in addition, NSC697923 can be used for preparing medicines for resisting colorectal cancer metastasis, thus having a significant clinical application value.
