Definitions
- the present invention relates to the prevention of adhesion after laparotomy.
- Adhesive ileus often develops several decades after surgery, and treatment for this often requires relapsing the laparotomy and requiring adhesion detachment. However, this results in further adhesions.
- adhesions after laparotomy were a major challenge, but were overlooked as an inevitable side effect.
- an absorptive membrane (Seprafilm; Kaken Pharmaceutical) has been developed to be placed in the abdominal cavity to prevent this. It cannot be effective. Further techniques for preventing post-operative intraperitoneal adhesions are desired. Disclosure of the invention
- the purpose of this study is to provide a new drug that prevents post-operative intraperitoneal adhesions.
- the present inventors systematically examined whether the degree of adhesion was different between mice having different genetic backgrounds.
- the mitdocaine gene knockout mouse mitdocaine (-/ _) mouse
- mitdocaine (-/ _) mouse had significantly less intraperitoneal adhesions to the wound created in the abdominal cavity than the wild type mouse.
- adhesion was suppressed in mitdocaine, mice, and mice, but when mitdocaine was given to these mice, the process was restarted. Migration of macrophages and neutrophils into the network was suppressed in mitdocaine (-/-) mice.
- mitdocaine is crucially involved in intraperitoneal adhesions and is a molecular target for suppressing it.
- Mitudocaine is a growth factor that promotes cell growth, migration and survival (Muramatsu, T. Wiley Encyclopedia Mol, 2086-2088, 2002; Muramat su, T., J. Biochem., 132, 359-371, 2002). ), Is known to induce neutrophils and macrophages to the site of inflammatory stimulation and play a part in the inflammatory response (Takada, T. et al., J. Biochem., 122, 453-458, 1997, Horiba, M. et al., J. Clin. Invest., 105, 489-495, 2000), and this finding has revealed that mitdocaine is also involved in adhesions.
- the present invention prevents adhesion by inhibiting the synthesis or action of mitdocaine.
- suppression of the expression of the mitodkine gene includes both suppression of transcription and translation.
- Oligonucleotides that suppress the expression of the mitdocaine gene include RNA complementary to the transcript of the mitdocaine gene or the RNA. Can be used. One embodiment of such a compound is an antisense oligonucleotide.
- Antisense oligonucleotides that strongly suppress the expression of mitdocaine have already been developed (Takei, Y. et al., Cancer Res., 61 8486-8491, 2001, Japanese Patent Application 200 2-142778, Japanese Patent Application 2002-47135). , 2002-47136).

- ⁇ oligonucleotide '' refers to the nucleic acid portions of naturally occurring oligomers, such as the deoxyribonucleotide and liponucleotide structures of DNA and RNA, as well as the ability to bind to naturally occurring nucleic acids. Includes both human and analog.
- Oligonucleotides of the invention may be based on liponucleotide monomers bound by a phosphodiester bond or by an analog linked by methylphosphonate, phosphorothioate, or other bond. They may also have a portion of the monomer that is altered in its basic structure or other modifications, but retains its ability to bind to naturally occurring DNA and RNA structures. Such oligonucleotides can be prepared by methods well known to Applicants, for example, using commercially available machines and reagents available from Perkin-Elmer / Applieds Biosystem (Foster City, CA).
- Phosphodiester-linked oligonucleotides are particularly susceptible to nuclease action in serum or inside cells, and in a preferred embodiment, the oligonucleotides of the invention have been shown to be nuclease resistant. These include analogs linked to holothioate or methylophosphonate (Stein et al, Cancer Research 48; 2659, 1998). The method developed by the applicants is also effective (Japanese Patent Application 2002-47136).
- the antisense oligonucleotide inhibits translation of the mitokine mRNA by hybridizing the RNA molecule produced by infecting the target cell with the expression construct to the mRNA. And then It is selected to inhibit the synthesis of midkine.
- Hybridization of this oligonucleotide with an mRNA target can inhibit the expression of the corresponding gene product by multiple mechanisms.
- translation arrested In the "translation arrested" state, translation of the target mRNA into protein is blocked (Haeuptle et al .; Nucl. Acids. Res. 14 .: 1427, 1986).
- intracellular RNase H can digest the target RNA sequence as soon as the target RA sequence hybridizes to the DNA oligomer (Walder & Walder Natl. Acad. Sci. USA. 85: 5011, 198 8).
- RNA polymerase Gaovannange li et al 1 .: Proc. Natl. Acad. Sci. USA. 90: 10013, 1993.

- dsRNA When RNAi first appeared, dsRNA was considered to be ineffective if it was not longer than a certain length (40 bases), but Tuschl et al. Of the Rockefeller University in the U.S. produced a single-stranded dsRNA (siRNA) of around 21 base pairs.
- PKR When introduced into cells, it has been reported that PKR does not cause an anti-viral reaction in mammalian cells and has an RNAi effect (Tuschl, Nature, 411, 494-498 (2001)). As a technology that can be applied to mammalian cells such as these, it has suddenly attracted attention.
- RNAi When RNAi is used to suppress the expression of the mitdocaine gene, sRNA may be used as dsRNA.
- siRNA refers to a double-stranded RNA consisting of short strands in a range that is not toxic in cells, and is not limited to the full length 21 to 23 base pairs reported by TuscW et al. There is no particular limitation as long as the length is within a range that does not indicate the above, for example, 15 to 49 base pairs, preferably 15 to 35 base pairs, and more preferably. Suitably it may be 21-30 base pairs.

- a peritoneal defect wound was created, and after hemostasis with bipolar, the abdomen was closed using nylon thread. Seven days later, the abdomen was opened by the same procedure, and the ratio of the adhesion area of the general rule to the created wound (the adhesion area of the general rule X 100 / the area of the created wound) was measured using the image analysis software Scion Image (Scion Corporation). .
