    摘要: The present invention relates to an inhibitor of mitoferrin-2 for use in treating a cancer with reduced activity of mitoferrin-1 in a subject. The present invention also relates to a method for identifying an inhibitor of mitoferrin-2 comprising (a) contacting a (i) host cell with a reduced mitoferrin-1 activity and (ii) a host cell with a non-reduced mitoferrin-1 activity with a candidate inhibitor of mitoferrin-2. (b) determining growth and/or morphology of the host cells of step (a): (c) identifying an inhibitor of mitoferrin-2 if a growth arrest and/or abnormal morphology is/are detected in step (b) in the host cell having the reduced activity of mitoferrin-1 but not in the host cell with the non-reduced activity of mitoferrin-1. The present invention further relates to a method for identifying a subject susceptible to cancer treatment by an inhibitor of mitoferrin-2, comprising (A) determining mitoferrin-1 activity in a sample of said subject, preferably a sample of cancer cells, and (B) identifying a patient susceptible to cancer treatment by an inhibitor of mitoferrin-2 based on determining step (A).

    摘要: A phantom calibration body (110) for a method for determining at least one quantitative diffusion parameter extracted for characterization of a tissue being suspicious to a tumorous modification in magnetic resonance imaging is disclosed, wherein the phantom calibration body (110) is designed for being characterized during characterization of the tissue by the magnetic resonance imaging. Herein, the phantom calibration body (110) comprises a first compartment (112) having a first cross-section, the first compartment (112) being filled with a first solution comprising a calibration substance having a first concentration; and a second compartment (114) having a second cross-section, the second cross-section having at least two different partitions with differing diameters, wherein the second compartment (114) is filled with a second solution comprising the calibration substance having a second concentration, the second concentration differing from the first concentration. The present invention allows determining absolute quantitative parameters in an individualized fashion for each individual tissue independent from various times of recording, applied software algorithms for post-processing of the raw MRI data, MR devices, or MR vendors. The present invention, thus, allows using the absolute quantitative data extracted from the phantom calibration body (110) measured with every tissue for comparability of quantitative data, being a prerequisite for introducing quantitative diffusion weighted imaging (DWI) into clinical routine.
