The antimutagenic activities of the total extract and several fractions of starfish, Asterina pectinifera (Asteriidae), were investigated in vitro by SOS chromotest with Escherichia coli PQ37 and Ames test with Salmonella typhimurium TA100. When various fractions was tested, the chloroform and butanol fractions showed low induction factors, which means both fractions increased antigenotoxicity against the base substitution mutagen MNNG. Even though higher antigenotoxic effect of the chloroform fraction, no effective result of Ames test was found in revertant formation of S. typhimurium TA100. The most effective antigenotoxic and antimutagenic fraction was a butanol one: I.e., When 0.5mg/tube of butanol fraction was applied, the induction factor was 0.68. As the concentration of the fraction was increased, an induction factor was significantly reduced to 0.47. The 2.5mg/tube of the fraction potently inhibited the formation of revertants of S. typhimurium TAIOO by about 81%. There was no cytotoxic effect of butanol fraction against S. typhimurium TA100. This result might be useful for further study to search a possible anticancer agent from the starfish, Asterina pectinifera.

Starfish, a species of Echinoderm, is widely known as a predator on benthic invertebrate. A series of fishing experiments was carried out in the western coastal waters of Korea from September, 2011 to November, 2012, using the drum-shaped pots of different mesh sizes (17.1, 24.8, 35.3, 39.8, and 48.3 ㎜) to describe the composition of the catch species and the mesh selectivity of the pot for starfish. Some species including fish, crab, and starfish were caught in the experimental pots. The SELECT (Share Each Length’s Catch Total) method was applied to describe the selectivity of the pot for starfish Asterina pectinifera. The master selection curve was estimated to be s(R) = exp(10.358R-4.086) / [1+exp(10.358R-4.086)], where R is the ratio of arm length to mesh size. The relative arm length of 50% retention was 0.395, and the selection range was 0.212. The results should be helpful to understand the relationship between the catch size of starfish and the mesh size of pot.

In this experiment, the effects of Asterina pectinifera extracts on the activation of immune cells were studied. An immune cell activating factor was partially purified from starfish, Asterina pectinifera, by means of physiological saline extraction, acetone precipitation and heating inactivation. Starfish extracts increased the proliferation of spleen cells and induced the production of IL-6 and $IFN-{\gamma}$ by spleen cells. Also, it increased the proliferation of purified B cells and production of IgM and IgG in the presence of Asterina pectinifera extracts. Starfish extract self-induced NO synthesis in mouse macrophage cell line (RAW264.7). When cell lines was treated with extracts, the mRNA expression of inducible NO synthetase (iNOS), $TNF-{\alpha}$, IL-6, and GM-CSF were markedly increased in RT-PCR analysis. Therefore starfish extract can self-activate spleen cells, B cells and macrophages. These results might be useful in further studies into a possible immune activating agent from the starfish, Asterina pectinifera, for the development of functional foods and drugs. 불가사리 추출물을 이용하여 생쥐 비장에 있는 면역세포 활성화 효과에 대해 실험한 결과, 다음과 같은 결과를 얻었다. 첫째, 별불가사리 추출물 중에서 B세포와 대식세포를 활성화시키는 성분은 아세톤처리로 추출할 수 있었다. 둘째, 이 성분은 농도 의존적으로 생쥐 비장세포의 증식반응을 유도하였으며, IL-6와 $IFN-{\gamma}$의 생산을 유도하였다. 셋째, 이 성분은 B세포의 증식을 유도하였으며, 이 때 면역글로불린 IgM과 IgG의 생산도 유도하였다. 넷째, 이 성분은 대식세포주의 일산화질소 생산을 유도하였으며, 또 $TNF-{\alpha}$, GM- CSF와 IL-6의 분비를 유도하였다. 이상의 실험 결과, 본 실험에서 사용한 별불가사리 추출물에는 B세포와 대식세포 같은 면역세포의 증식과 각종 사이토카인을 생산을 유도하여, 면역반응을 조절하는 성분이 포함되어 있는 것으로 생각된다.

The effect of protein extract from Asterina pectinifera on proliferation of human breast cancer cells and activities of cytochrome P450 1A1 and ornithine decarboxylase was tested. Protein extract from Asterina pectinifera inhibited the growth of both estrogen-dependent MCF-7 and estrogen-independent MDA-MB-231 human breast cancer cells. Cytochrome P450 1A1 activity was significantly inhibited by the protein extract from Asterina pectinifera at concentrations of 80 (p<0.05), 120 (p<0.01) and $160{\mu}g/m{\ell}$ (p<0.01). The extract inhibited induction of ornithine decarboxylase by 12-O-tetradecanoylphorbol-13-acetate, a key enzyme of polyamine biosynthesis, which is enhanced in breast tumor promotion. Therefore, Asterina pectinifera is worth further investigation with respect to breast cancer chemoprevention or therapy. 별불가사리 단백추출물을 조제하여 유방암 유발억제효과를 측정한 결과, 별불가사리 단백추출물은 estrogen-의존성의 유방암세포(MCF-7)와 estrogen-비의존성 유방암세포(MDA-MB-231)의 증식을 농도의존적으로 억제하는 효과가 있었으며, 유방암발생 발암물질 활성에 관여하는 cytochrome P450 1A1 활성도 저해하였다. 또한 유방암발생의 촉진단계에 주요한 기능을 가진 ODC 활성도 억제하였으므로 별불가사리 단백추출물은 유방암 발생을 저해할 것으로 기대된다.

This study aimed to elucidate anti-inflammatory activities from extracts of Asterina pectinifera on nitric oxide (NO) production, TNF-α and IL-6 release in lipopolysaccharide (LPS)-stimulated murine macrophage cell, RAW264.7. We prepared the methanolic extracts (60-MAP, 70-MAP, 80-MAP and 90-MAP), aqueous extract (W-AP) and functional bioactive compound fraction (He-AP and EA-AP) from Asterina pectinifera according to extract method. The 60-MAP, 70-MAP, 80-MAP, 90-MAP and W-AP were significantly suppressed LPS-induced production NO, TNF-α and IL-6 secretion in a concentration-dependent manner (P < 0.05). Especially, 80-MAP by extracted 80% methanol had the strongest activity in reduction of inflammatory mediators among these extracts. Indeed, to identify active fraction, which contained potential bioactive compounds, from 80-MAP of Asterina pectinifera, we tested anti-inflammatory activity of the He-AP or the EA-AP. The He-AP was next extracted from 80-MAP and the EA-AP were extracted from the other methanol layer except the He-AP. The EA-AP demonstrated a strong anti-inflammatory effect through its ability to reduce NO production and it also inhibited the production of proinflammatory cytokines such as IL-6 and TNF-α at low concentration. These results suggested that the methanolic extract from Asterina pectinifera had the potential inhibitory effects on the production of these inflammatory mediators.

조우진,이현화,정연정,김훈,정은정,박시향,임치원,차용준 한국수산과학회 2015 한국수산과학회지 Vol.48 No.4

This study examined the antimicrobial, antioxidant, and tyrosinase inhibitory activities of bioactive compounds extracted from two starfish, Asterina pectinifera and Asterias amurensis, using solvent extraction after Protamex™ hydrolysis. Methanol and acetone fractions collected by stepwise extraction from specimens were subjected to silica gel column chromatography (SGCC) (200 mesh and 400 mesh), followed by high-performance liquid chromatography (HPLC). Two fractions (7:3 and 5:5 chloroform : methanol ratio, v/v) eluted using silica gel column chromatography from the two starfishes showed higher antimicrobial activity against Propionibacterium acnes and dermatophyte fungi (Epidermophyton floccosum, Microsporum audouinii, Trichophyton ferrugineum, Trichophyton mentagrophytes, and Trichophyton rubrum), antioxidant activity (EDA50, mg/mL), and tyrosinase inhibitory activity compared to the other fractions. The final fractions obtained from Asterina pectinifera (RT 7.53, 8.93, and 10.48 min) and Asterias amurensis (RT 5.02 min) by SGCC (400 mesh) and HPLC from two SGCC fractions (200 mesh) showed 8.94 and 15.59 mg/mL antioxidant activity (EDA50) and 46.89 and 40.19 % tyrosinase inhibitory activity, respectively. Extracts from starfishes are potential cosmetic basic material.

Chemopreventive Effect of Protein Extract of Asterina pectinifera in HT-29 Human Colon Adenocarcinoma Cells

Yun-Hee Shon,Kyung-Soo Nam 대한약학회 2006 Archives of Pharmacal Research Vol.29 No.3

We investigated the effect of protein extract of Asterina pectinifera on the activity of 4 enzymes that may play a role in adenocarcinoma of the colon: quinone reductase (QR), glutathione Stransferase (GST), ornithine decarboxylase (ODC), and cyclooxygenase (COX)-2. QR and GST activity increased in HT-29 human colon adenocarcinoma cells increased that had been exposed to 4 concentrations of the protein extract (80, 160, 200, and 240 µg/mL). Additionally, 12-O-tetradecanoylphorbol-13-acetate (TPA)-induced ODC activity decreased significantly in cells exposed to the extract in concentrations of 160 µg/mL (p<0.05), 200 µg/mL (p<0.005), and 240 µg/mL (p<0.005). TPA-induced COX-2 activity also decreased in cells exposed to extract concentrations of 10, 20, 40, and 60 µg/mL. COX-2 expression was also inhibited in cells exposed to this extract. These results suggest that this protein extract of A pectinifera has chemopreventive activity in HT-29 human colon adenocarcinoma cells, and therefore, may have the potential to function as a chemopreventive agent in human colorectal cancer.

별불가사리 단백추출물이 유방암예방 및 전이억제 효소계에 미치는 영향

별불가사리 단백추출물을 조제하여 유방암 발생 및 전이억제효과를 측정한 결과 종양세포증식에 관여하는 aromatase 활성이 농도의존적으로 억제효과가 있었으며, 침윤성 유방암에서 과발현하는 COX-2 단백질 발현을 억제하였다. 그리고 유방암이 진행될수록 활성이 증가하는 MMP-9도 농도의존적 저해율을 보였다. 그러므로 별불가사리 단백추출물은 유방암억제기전에 관련된 더 많은 연구를 통하여 유방암 예방물질로서 개발 가능성이 있는 것으로 보인다. The effect of protein extract from Asterina pectinifera on breast cancer chemopreventive (aromatase and cyclooxygenase-2) and metastatic (matrix metalloproteinase) enzymes was tested. Protein extract from A. pectinifera was capable of suppressing aromatase in a human placenta microsomal assay. Cyclooxygenase-2 (COX-2) activity was significantly inhibited by the protein extract from A. pectinifera at concentrations of 10, 20 and $40{\mu}g/m{\ell}$. The extract markedly reduced 12-O-tetradecanoylphorbol-13-acetate (TPA)-stimulated matrix metalloproteinase (MMP)-9 activity. These results suggest that A. pectinifera could be of therapeutic value in preventing human breast cancer.
