Abstract: A nucleic acid amplification method using a solid-phase carrier according to the present invention comprises: capturing a target nucleic acid comprising mRNA on a solid-phase carrier; carrying out complementary-strand synthesis on the solid phase; carrying out exonuclease treatment to degrade and remove unreacted target- capturing nucleic acid on the solid phase; and then carrying out mRNA degradation and homopolymer addition by TdT reaction in the presence of a chain-terminating nucleotide triphosphate. According to the method of the present invention, cDNA can be stably and highly efficiently amplified even from a small amount of sample even in cases where the ratio of the amount of enzyme to the DNA substrate on the solid phase is excessive, where the reaction time is excessive, and/or where reagents show lot-to-lot variation.

Abstract: Disclosed is a novel measure that is effective in therapy etc. of psychiatric or neurological disorders or symptoms, such as anxiety or depressive disorders, and is unlikely to cause problems such as dependence and adverse effects and is highly safe. The present invention provides an agent for treating, preventing, or ameliorating psychiatric or neurological disorders or symptoms, wherein the agent contains any of the followings as an active ingredient: (1) disulfiram, (2) a metal complex of diethyldithiocarbamate, (3) a disulfide capable of generating diethyldithiocarbamate in the body, (4) a pharmaceutically acceptable salt of (1), (2), or (3), and (5) a solvate of (1), (2), (3), or (4).

Abstract: Novel means that enables prediction of prognosis of a patient with cancer or inflammatory disease is disclosed. In the method for prediction of prognosis of a patient with cancer or inflammatory disease according to the present invention, the expression level of the FROUNT gene in a sample collected from the patient is measured. Since FROUNT is a poor prognostic factor, the lower the expression level of the FROUNT gene is, the better the prognosis in the patient is predicted to be. Or, the expression level of the CC chemokine receptor/ligand gene in a sample collected from the patient is measured. Since the CC chemokine receptor/ligand gene such as CCR2 or CCR5 is a good prognostic factor, the higher the expression level of the CC chemokine receptor/ligand gene is, the better the prognosis in the patient is predicted to be.

Abstract: Disclosed is a means for reducing side effects of an immune checkpoint regulator that is used as an anticancer drug or the like. A side-effect reducing agent according to the present invention comprises as an effective ingredient an anti-CD4 antibody having a high cytotoxic activity, or an anti-CD4 antibody or antigen-binding fragment thereof which antibody or fragment comprises a cytotoxic component bound thereto. The anti-CD4 antibody is a human-type chimeric antibody, humanized antibody or human antibody against human CD4. The immune checkpoint regulator may be, for example, an anti-PD-L1 antibody, an antagonistic anti-CTLA-4 antibody, or an agonistic anti-OX40 antibody.

Abstract: Disclosed is a novel means that is effective for analgesia or sedation. The analgesic or sedative agent of the present invention comprises, an active component, disulfiram, a metal complex of diethyldithiocarbamate, a disulfide capable of generating diethyldithiocarbamate in the body, a pharmaceutically acceptable salt of any of these compounds, or a solvate of any of these compounds or salts thereof. Disulfiram and the above-described metal complex are known to have anticancer and anti-inflammatory effects. The agent of the present invention can exert multiple therapeutic benefits such as anticancer, anti-inflammatory, analgesic, and sedative effects, in cancer patients.
