摘要:
Disclosed is a topical therapeutic agent for ophthalmic diseases, which comprises a compound capable of binding specifically to a DNA sequence. More preferably disclosed is a topical therapeutic agent for ophthalmic diseases, which comprise a pyrrole-imidazole polyamide having a specific structure. The topical therapeutic agent for ophthalmic diseases comprises a pyrrole-imidazole polyamide which can inhibit transforming growth factor-β gene and matrix metalloproteinase 9 gene.
摘要:
Disclosed are: an inhibitor of the expression of matrix metalloproteinase-9 gene; a therapeutic agent for a disease associated with matrix metalloproteinase-9; and a carcinostatic agent. Each of the agents comprises a pyrrole-imidazole polyamide having an N-methylpyrrole unit, an N-methylimidazole unit and a γ-aminobutyric acid unit. The pyrrole-imidazole polyamide can be folded at the site of the γ-aminobutyric acid unit to form a U-shaped conformation in a minor groove of a double-stranded domain comprising a part or the whole of a specific nucleotide sequence (SEQ ID NO:2, SEQ ID NO:4) included in a human matrix metalloproteinase-9 gene promoter and a strand complementary to the part or the whole of the specific nucleotide sequence. In the U-shaped conformation, a Py-Im pair, an Im/Py pair and a Py/Py pair in the pyrrole-imidazole polyamide target a C-G base pair, a G-C base pair, and both of an A-T base pair and a T-A base pair in the minor groove, respectively.

摘要:
In the present invention, the methylation of the genomic DNA a Zar1 gene specifically found in proliferative disease is used as a marker. Specifically, the present invention provides a method for detecting proliferative disease, which comprises detecting the methylation of the genomic DNA of a Zar1 gene in a biological sample. There is thereby provided a method for detecting proliferative disease, using a marker having a high detection rate and a low false positive rate.

摘要:
The present invention provides a target gene-specific histone modification regulator, which comprises a conjugate between a histone modification regulator and a polyamide capable of recognizing a regulatory region in a target gene. This enables the provision of a target gene-specific histone modification regulator.
摘要:
An engine includes: a carburetor configured to supply an air-fuel mixture of fuel and air; a crank case defining a crank chamber; a cylinder block which includes: a cylinder bore in which a reciprocable piston is disposed; and an intake port which supplies the air-fuel mixture supplied from the carburetor to the crank chamber; a control valve configured to open and close the intake port; and a controller configured to control the control valve. The controller controls the number of times that the control valve closes the intake port with respect to the number of times that the piston moves up to thereby reduce pressure of the crank chamber.
