Abstract: An object of the present invention is to provide a novel marker for rheumatoid arthritis (RA), and more specifically, to provide a marker whose expression may be specifically increased or decreased in RA. Another object of the present invention is to confirm whether or not miRNA serving as the marker is involved as the etiology of RA, and to provide an inspection method for RA and a therapeutic agent for RA each using the miRNA involved. The marker includes miRNA (for example, miR124a) whose expression is specifically increased or decreased in RA synovial cells based on a small RNA expression profile in the RA synovial cells. In addition, the therapeutic agent for RA includes miRNA (for example, miR124a) as an active ingredient.

Abstract: A server 100 of a program creation company presents program plan information representing a program plan displayed in a form of a list, to a terminal 200 through Internet 10. A user of the terminal 200 browses the program plan information. In a case where there is a program plan that the user desires to invest, the user informs the server 100 of information representing that the user desires to invest and representing a desired investment amount. The server 100 accepts subscription for investment from the terminal 200 for a predetermined period of time. The server 100 compares the total amount of investment and the estimated creation cost, and determines whether or not the program can be created. In a case where the program can be created, a predetermined billing process for an investor is carried out. The program creation company creates the program using the collected investment, and distributes the program to the terminal 200 through the Internet 10 from the server 100.
