Mouse thymosin β-4 (TB4) 유전자를 Escherichia coli에서 intein-tag 융합 단백질로 발현시키고 정제하였다. 재조합 TB4-intein 융합 단백질의 분자량을 10% glycine SDS-PAGE로 확인한 결과, 세포내 soluble 분획에서 60 kDa의 단백질을 얻을 수 있었고, 유도발현 최적 조건은 0.1 mM IPTG, 25℃에서 3시간 동안 유도 발현할 때가 최적임을 확인하였다. TB4 만을 얻기 위해서 유도발현된 TB4-intein을 DTT를 이용해 self-cleavage를 일으킨 다음, chitin bead를 이용한 친화성 크로마토그라피로 정제 후 분자량을 확인 한 결과, 5 kDa으로 확인되었으며, 순도는 95% 이상 이었다. 정제한 recombinant TB4가 생물학적 기능을 보유하고 있는지 확인을 하기 위하여, TB4를 농도 별(1~1,000 ng/ml)로 하여 HT1080 cell을 이용한 cell migration을 측정한 결과, 모든 농도에서 recombinant TB4가 화학합성한 TB4 보다 약 20% 이상 높은 활성을 보였으며, recombinant TB4 1 ng/ml의 농도에서 cell migration 활성이 가장 높게 나타났다. Recombinant TB4를 마우스 상처 부위에 5일 동안 매일 처리한 결과(최종 처리 농도 0.5 mg/ml), 화학합성 TB4 보다 recombinant TB4의 상처치유 활성이 약 35% 더 높음을 알 수 있었다. 이상의 결과는 recombinant TB4가 화학합성 TB4보다 cell migration과 상처치유에 훨씬 높은 활성을 나타냄을 보여주고 있다.
Thymosin β-4 (TB4) is a small peptide composed of 43 amino acids. To obtain sufficient biologically active mouse TB4 economically, we cloned and overexpressed this gene in an Escherichia coli system. With the isopropyl β-D-1-thiogalactopyranoside induction of the E. coli transformant, TB4 fusion protein with intein- and chitin-binding domain was successfully expressed in the soluble fraction within the E. coli cell. The TB4-intein–chitin-binding domain fusion protein was purified from the soluble fraction of E. coli cell lysate. The affinity chromatography with chitin beads and dithiothreitol-mediated intein self-cleavage reaction releases the TB4 peptide into the stripping solution. Sodium dodecyl sulphate–polyacrylamide gel electrophoresis and Western blot analyses were used to confirm that the recombinant TB4 peptide was produced with the expected size of 5 kDa. We found that the recombinant TB4 stimulated cell migration in the transwell plate chamber assay. After 18 hr of the treatment of the recombinant TB4 with 1 ng/ml concentration, the migration of the HT1080 cell was increased by 20% compared with that of the chemically synthesized TB4. The recombinant TB4 was also observed to promote the healing of a wound area in C57BL/6 mice by as high as 35% compared with that of the chemically synthesized TB4. These results suggest that the recombinant TB4 has better biological activity for cell migration and wound healing than that of the chemically synthesized TB4 peptide.번호 | 참고문헌 | 국회도서관 소장유무 |
