Definitions
- the present invention relates to an antisense oligonucleotide that alters the splicing of DUX4 pre-mRNA.
- Facioscapulohumeral muscular dystrophy is a muscular dystrophy that shows strong muscle atrophy and weakness in the facioscapulohumeral muscles around the shoulder blades and upper arms (Non-Patent Document 1: Tawil R. and Van Der Maarel). SM Muscle Nerve 2006, 34: 1-15). The onset period is very wide, from 0 to 60s, but generally from around teens, symptoms such as difficulty in raising arms, whistling, and poor facial expression occur. Symptoms progress slowly, but the lower limbs are gradually impaired, often resulting in impaired walking. In addition, the degree of muscle damage is often different on the left and right.
- Non-Patent Document 2 Arahata et al., Muscle Nerve 1995, 2: S56- S66.
- Non-Patent Document 3 Padberg et al., Muscle Nerve 1995, 2: S73-S80. It is considered to be the second most common muscular disease after Duchenne muscular dystrophy and myotonic muscular dystrophy, and the prevalence is reported to be 1 in 14,000 to 20,000 in Europe and the United States (Non-Patent Document 4: Padberg et).

- Non-Patent Document 8 Lemmers et al. ., Science 2010, 329: 1650-1653.
- FSHD takes the form of dominant inheritance, and the disease is linked to the end of the long arm of chromosome 4 (4q35 region) (Non-Patent Document 9: Wijmenga et al., Nat Genet 1992, 2: 26-30).
- D4Z4 In this 4q35 region, there is a region called D4Z4 in which a 3.3 kb sequence is repeated (D4Z4 repeat), which is normally repeated 11-100 times and is in a highly DNA-methylated heterochromatin state.
- D4Z4 repeats on one chromosome 4 were shortened to 10 times or less, and as a result, DNA methylation in the 4q35 region was reduced (Non-Patent Document 10: van Overveld et al., Nat Genet 2003, 35: 315-317).
- FSHD1 type The type in which this shortening of D4Z4 repeat is seen.
- FSHD2 type a normal D4Z4 repeat count
- SMCHD1 SMCHD1 gene involved in the methylation of D4Z4 repeats
- Non-Patent Document 12 Gabriels et al., Gene 1999, 236: 25-32.
- Expression of DUX4 in skeletal muscle occurs frequently only when the following two conditions are met. The first is a decrease in DNA methylation in the D4Z4 region and a loosening of the heterochromatin structure. The second is that the haplotypes called 4qA and 4qB existing on the 3'side of the D4Z4 repeat are 4qA (Non-Patent Document 13: Lemmers et al., Am J Hum Genet 2007, 81: 884-894). ..
- the 4qA sequence contains a polyA addition sequence (ATTAAA) and acts as a polyA addition sequence that stabilizes DUX4 mRNA (Non-Patent Document 14: Lemmers et al., Science 2010, 329: 1650-1653). Since the 4qB sequence does not contain the polyA addition sequence, FSHD does not develop in people whose D4Z4 repeat of alleles with the 4qB sequence is shortened to 10 or less.
- DUX4 encodes a transcription factor and can produce transcription products DUX4-fl and DUX4-s by alternative splicing (Non-Patent Document 15: Snider et al., PLoS Genet 2010, 6: e1001181). Full-length DUX4-fl is frequently expressed in FSHD patients (Non-Patent Document 16: Jones et al., Hum Mol Genet 2012, 21: 4419-4430), via the transcriptional activation domain at the C-terminus.

- short-type DUX4-s is slightly expressed in cells derived from healthy humans, but does not function as a transcription factor because it does not have a transcription activation domain.
- the DUX4-fl protein activates the expression of genes expressed in early embryos and testis such as PRAMEF2, TRIM43, and ZSCAN4 (Non-Patent Document 19: Geng et al., Dev Cell 2012, 22: 38-51).

It is believed that there is.
- Non-Patent Document 32 De laco et al., Nat Genet 2017, 49: 941-945; Non-Patent Document 33: Hendrickson et al., Nat Genet 2017, 49. : 925-934).
- DUX4-fl and DUX4-s have a common DNA binding domain on the N-terminal side. Therefore, when DUX4-fl and DUX4-s are present at the same time, they are considered to bind competitively to the same DNA. In experiments using cultured cells, when DUX4-fl and DUX4-s were introduced at a ratio of 1: 1, luciferase activation by DUX4-fl was suppressed to about 20%.
- Non-Patent Document 34 Geng et al., Dev Cell 2012, 22: 38-51
- DUX4-fl muscular dystrophy caused by DUX4-fl was observed.
- Symptoms were alleviated
- Non-Patent Document 35 Mitsuhashi et al., Hum Mol Genet 2013, 22: 568-577. Since DUX4-s has no transcription-promoting activity, it is considered to be the result of competitive inhibition of the target gene.
- An object of the present invention is to establish a new treatment method for facial scapulohumeral muscular dystrophy.

実施例1と同様の条件で合成することにより、下記の表2に記載の化合物も合成することができる。
(A)DUX4ミニジーンコンストラクトの構築
DUX4遺伝子を含むBACクローンRP11-242C23(Morioka et al., PLoS One 2016, 11: e0151963)を保持する遺伝子組換え大腸菌を、Children's Hospital OaklandのBAC PAC Resources Centerから購入した。LB/クロラムフェニコール寒天培地で培養し、QIAGEN plasmid midi kit (QIAGEN, cat.no.12143)を用いてプロトコルQP01にしたがってBAC DNAを精製した。
ヒト子宮頸部癌由来培養細胞株であるHeLa細胞は、理研BRC Cell Bankより購入した(cat. RCB0007, Tsukuba, Japan)。HeLa細胞は10% FBS (Thermofisher scientific; cat.no.10270-106)を含むDMEM (SIGMA; cat.no.D5796)中で、 37°C、CO2濃度5%の条件で培養した。 6ウェルディッシュ(Thermofisher scientific; cat.no.140675)にHeLa細胞を56 x 104個播種し、翌日、DUX4ミニジーンコンストラクト1μgと実施例の化合物(最終濃度100nM)をリポフェクタミン2000(Thermofisher scientific; cat.no.11668027)を用いて導入した。
DUX4ミニジーンコンストラクトをトランスフェクションした後、24時間で細胞を回収し、RNeasy mini kit(QIAGEN; cat.no.74104)でRNAを抽出した。PrimeScript(Takara; cat.no.2680A)を用いて逆転写をおこない、DUX4-fl、DUX4-s 両方を増幅するプライマー(プライマー222: 5’-GGATTCAGATCTGGTTTCAGAATCGAAGG-3’ (配列番号90), プライマー225: 5’-CCAGGAGATGTAACTCTAATCCAGGTTTGC-3’ (配列番号91))でPCRをおこなった。4.8%ポリアクリルアミドゲル電気泳動でDUX4-flとDUX4-sのバンドを分離し、バンド強度をLAS3000(Fujifilm)で可視化した。マーカーとして、λ/EcoT14Iマーカー(Takara; cat.no.3010をTakara;cat.no.1038Aで処理、図中、M1として使用)、100bpマーカー(Takara;cat.no.3422B, 図中、M2として使用)を使用した。
DUX4ミニジーンコンストラクトをトランスフェクションした後、24時間で細胞を回収し、RNeasy mini kitでRNAを抽出した。PrimeScriptを用いて逆転写をおこない、DUX4-fl、DUX4-s 両方を増幅するプライマー(プライマー222, 225)でPCRをおこなった。2%アガロースゲル電気泳動にてDUX4-flとDUX4-sのバンドを分離し、約300bpのバンドを切り出し、MinElute Gel Extraction kitでDNAを精製し、Mighty mixを用いてpCR bluntベクターにライゲーションした。組換えプラスミドDNAを大腸菌TOP10コンピテントセルに形質転換し、LB/カナマイシン寒天培地で選択した。形質転換体のコロニーを液体培養し、GenElute plasmid miniprep kitで組換えプラスミドDNAを精製した。得られた組換えプラスミドDNAを鋳型にM13 forwardプライマー(5’- CGACGTTGTAAAACGACGGCCAGT-3’ (配列番号92))、M13 reverseプライマー(5’- ggaaacagctatgaccatgattac-3’ (配列番号93))でサンガー反応をおこない、ABI 3500xL Genetic Analyzerで塩基配列を解析した。その結果DUX4-sの配列(Genbank HQ266762)と比べ、エクソン2の3’末端10bpが欠失した配列であった。DUX4-sの終止コドンはエソン2の先頭に存在するため、本実験で確認された配列からも全長のDUX4-sタンパク質(GenBank: ADN68617.1)が産生されると考えられる。
DUX4ミニジーンコンストラクトと実施例の化合物(DUX4-009)をトランスフェクションした後、24時間で細胞を回収し、RNeasy mini kitでRNAを抽出した。PrimeScriptを用いて逆転写をおこないcDNAを合成した。そのcDNAを鋳型として用い、DUX4が転写を活性化する標的遺伝子として知られているZSCAN4, MBD3L2, TRIM43の発現量をPowerUP SYBR Green PCR master mix (Thermofisher scientific; cat.no. A25742)を用いたリアルタイムPCRで測定した。PCRはStepOne Plus(Thermofisher scientific)を用い、内部標準としてRPL13A遺伝子を用いたΔΔCt法で数値化した。用いたプライマーの配列は以下の通りである。
ZSCAN4-Fw: 5’-TGGAAATCAAGTGGCAAAAA-3’ (配列番号94); ZSCAN4-Rv: 5’-CTGCATGTGGACGTGGAC-3’ (配列番号95)
MBD3L2-Fw: 5’-GCGTTCACCTCTTTTCCAAG-3’ (配列番号96); MBD3L2-Rv: 5’-GCCATGTGGATTTCTCGTTT-3’ (配列番号97)
TRIM43-Fw: 5’-ACCCATCACTGGACTGGTGT-3’ (配列番号98); TRIM43-Rv: 5’-CACATCCTCAAAGAGCCTGA-3’ (配列番号99)
その結果を図8ABに示す。DUX4ミニジーンコンストラクトと実施例の化合物(図8A:DUX4-009, DUX4-031, DUX4-036, DUX4-048、図8B:DUX4-48.7, DUX4-48.11, DUX4-48.12, DUX4-48.13, DUX4-52.2)をトランスフェクションした細胞は、DUX4ミニジーンコンストラクトのみをトランスフェクションした細胞と比較して、ZSCAN4, MBD3L2, TRIM43の発現量の低下が認められた。
(試験例2)
(A)DUX4 pre-mRNA (D4Z4 mRNA)の調製
HeLa細胞の実験で用いているDUX4ミニジーンコンストラクトをEcoRIとXhoIで切断し、断片をアガロースゲル電気泳動で分離した。ゲルからDNAを精製し、SP6プロモーターを持つpCS2-V5ベクターへライゲーションした。得られたプラスミドDUX4_pCS2をNotIで線状化し、それを鋳型としてmMessage mMachine SP6 transcription kit (ThermoFisher scientific; cat.no.AM1340)を用いてmRNAをin vitro合成し、RNeasy MinElute Cleanup kit (QIAGEN; cat.no.74204)で精製した。
(B)ゼブラフィッシュへのD4Z4 mRNAと実施例の化合物のインジェクション、及び、 DUX4 pre-mRNAのスプライシングの変化の検出
野生型ゼブラフィッシュ系統RIKEN WTの受精卵約100個にDUX4 pre-mRNA (終濃度:10ng/μl)のみ、またはDUX4 pre-mRNAと実施例化合物DUX-048(終濃度:500μM)の混合液を、マイクロインジェクター(Eppendorf)で1nL注入した。5時間後にTRIzol reagent (ThermoFisher scientific; cat.no.15596026)を加えて受精卵をホモジナイズし、RNeasy Mini kitを用いてRNAを精製した。RNase-free DNase set (QIAGEN; cat.no.79254)を用いてDNase処理をおこなった。得られたRNAの一部をRT-用サンプルとし、1.2μg分をPrimeScript 1st strand cDNA synthesis kitを用いて逆転写した。得られたcDNAを鋳型に、プライマー222(配列番号90), プライマー225(配列番号91)を用いPrimeSTAR GXL DNA polymerase(Takara; cat.no.R050A)によるPCRをおこなった。4.8%ポリアクリルアミドゲル電気泳動でDUX4-flとDUX4-sのバンドを分離し、バンド強度をLAS3000(Fujifilm)で可視化した。λ/EcoT14Iマーカー(Takara; cat.no.3010をTakara;cat.no.1038Aで処理、図中、M1として使用)、100bpマーカー(Takara;cat.no.3422B, 図中、M2として使用)を使用した。
その結果を図9に示す。逆転写を行わなかった陰性対照(RT-)では予想通りバンドが検出されなかったことからプライマーの特異性が確認された。一方、逆転写をおこなったサンプル(RT+)では、実施例化合物(DUX-048)をインジェクトしたものでDUX4-fl相当のバンドが減少し、DUX4-s相当のバンドが増加した。
