Abstract: The present invention provides a pharmaceutical composition for use in treating acute myeloid leukemia (AML) and a method of treating AML in a patient in need thereof. The present invention also provides a method for predicting the sensitivity to the treatment in the patient using gene expression signature.

Abstract: Provided are gene signatures that are predictive of the sensitivity of a cancer or tumor to an MDM2i or an antagonist of the MDM2-p53 interaction. Differentially expressed genes in the provided gene signatures serve as biomarkers for determining and assessing the sensitivity of cancer and tumor samples to treatment or therapy with an MDM2i. Also provided are methods of determining MDM2i sensitivity of a test sample such as different cancer and tumor types and subtypes, based on the expression of genes in the MDM2i sensitive gene signatures in reference samples and the test sample even if all of the MDM2i sensitivities of the reference samples are unknown, and treating individuals with an MDM2i if their cancers are determined to be MDM2i-sensitive, based on the practice of the described methods. TP53 gene and p53 protein status can also be determined for the samples undergoing analysis for MDM2i sensitivity.

Methods, platforms, kits, reagents, and compositions of the invention provide advantageous approaches and tools for personalized or individualized treatments of cancer patients whose cancers exhibit sensitivity to MDM2 inhibitors.

Abstract: The present invention provides a retroviral vector containing a membrane protein having a hemagglutinin activity. The present inventors constructed a retroviral vector pseudotyped by the membrane protein having a hemagglutinin activity. This viral vector showed gene transfer at a high efficiency into host cells. In particular, it was established that genes can be transferred thereby at a high efficiency into cells into which genes can hardly be transferred by the conventional techniques, for example, blood cells and hematopoietic cells including hematopoietic stem cells, and mucous cells including mucosa epithelial cells. The viral vector of the present invention is highly useful as a vector for gene therapy.

Abstract: A vector expressing two foreign genes by using RRE sequence and controlling the ratio of the expression doses of these genes owing to the modification is provided. This vector, which can be provided as a lentivirus vector based on SIVagm, is constructed by modifying a virus-origin expression regulatory sequence into another expression regulatory sequence so as to eliminate the dependency on the virus-origin protein. Although this vector has a packaging signal, it has been modified so that the risk of the occurrence of wild strains due to gene recombination is lowered and no virus structural protein is expressed. This vector is highly useful as a gene therapeutic vector with a need for transferring two genes while controlling the expression doses or expression dose ration thereof.
