Objective: Skeletal muscle satellite cells (SMSCs) are significant for the growth, regeneration, and maintenance of skeletal muscle after birth. However, currently, few studies have been performed on the isolation, culture and inducing differentiation of goose muscle satellite cells. Previous studies have shown that C1q and tumor necrosis factor-related protein 3 (CTRP3) participated in the process of muscle growth and development, but its role in the goose skeletal muscle development is not yet clear. This study aimed to isolate, culture, and identify the goose SMSCs in vitro. Additionally, to explore the function of CTRP3 in goose SMSCs. Methods: Goose SMSCs were isolated using 0.25% trypsin from leg muscle (LM) of 15 to 20 day fertilized goose eggs. Cell differentiation was induced by transferring the cells to differentiation medium with 2% horse serum and 1% penicillin streptomycin. Immunofluorescence staining of Desmin and Pax7 was used to identify goose SMSCs. Quantitative realtime polymerase chain reaction and western blot were applied to explore developmental expression profile of CTRP3 in LM and the regulation of CTRP3 on myosin heavy chains (MyHC), myogenin (MyoG) expression and Notch signaling pathway related genes expression. Results: The goose SMSCs were successfully isolated and cultured. The expression of Pax7 and Desmin were observed in the isolated cells. The expression of CTRP3 decreased significantly during leg muscle development. Overexpression of CTRP3 could enhance the expression of two myogenic differentiation marker genes, MyHC and MyoG. But knockdown of CTRP3 suppressed their expression. Furthermore, CTRP3 could repress the mRNA level of Notch signaling pathway-related genes, notch receptor 1, notch receptor 2 and hairy/enhancer-of-split related with YRPW motif 1, which previously showed a negative regulation in myoblast differentiation. Conclusion: These findings provide a useful cell model for the future research on goose muscle development and suggest that CTRP3 may play an essential role in skeletal muscle growth of goose.

본 연구는 아이스플랜트의 생리활성을 향상시키고, 식생활에서의 활용가능성을 높이기 위하여 물김치 형태로 발효시켰으며, 아이스플랜트의 성분 및 몇 가지 생리활성을 발효 전과 비교하였다. 물김치 침지액의 pH는 발효 6일째까지 계속해서 낮아졌으며, lactic acid의 생성량은 발효 4일째에 가장 많았다. 아이스플랜트 물김치 건더기 중의 D-pinitol은 발효 전 $4.196{\pm}0.096mg/g$에서 6일째에는 $3.843{\pm}0.116mg/g$으로 감소하였다. 그러나 myo-inositol과 D-chiro-inositol은 각각 발효 전 $0.453{\pm}0.022$와 $2.815{\pm}0.008mg/g$에서 6일째에 $0.630{\pm}0.029$와 $4.117{\pm}0.096mg/g$으로 증가하였다. 아이스플랜트 추출물의 DPPH, ABTS radical 소거활성 및 FRAP 활성은 대체로 발효 후에 높게 나타나 유사한 경향이었으며, 1 mg/ml의 농도로 처리하였을 때 각각 발효 5일째($79.09{\pm}0.69%$), 4일째($87.55{\pm}1.21%$) 및 6일째($78.72{\pm}0.99%$)에 가장 높았다. Lipid/MA assay에 의한 항산화 활성도 대체로 발효 후에 높게 나타나 유사한 경향이었으며, 추출물을 $500{\mu}g/ml$ 처리하였을 때, 발효 4일째에 가장 높은 활성($64.65{\pm}1.63%$)을 나타났으며, 발효 5, 6일째에는 낮아지는 경향이었다. 아이스플랜트 추출물의 t-BHP, $H_2O_2$ 및 ethanol에 의하여 손상된 BNL CL.2 세포의 생존율은 각각 $14.19{\pm}0.98$, $13.80{\pm}2.25$ 및 $25.89{\pm}2.90%$이었으나, 추출물을 $200{\mu}g/ml$의 농도로 처리하였을 경우, 각각 발효 6일째에 $50.07{\pm}4.85%$, 2일째에 57.06% 및 4일째에 $66.06{\pm}1.36%$의 세포생존율을 나타내어 간세포가 회복되고 있음을 알 수 있었다. 그러나 발효 후에 간세포 보호효과가 뚜렷이 증가하지는 않았다. ${\alpha}-Glucosidase$ 저해활성은 모든 실험군에서 $83.52{\pm}2.69{\sim}92.79{\pm}2.16%$로 상당히 높게 나타났으며, 발효기간이 경과함에 따라 조금씩 증가하였다. 한편 ${\alpha}-Amylase$ 저해활성은 전체적으로 $52.64{\pm}3.26{\sim}57.56{\pm}1.21%$로 나타났으며 발효 전후에 뚜렷한 차이가 없었다. 이와 같은 결과로 볼 때, 아이스플랜트의 물김치 발효기간은 4~5일이 적정할 것으로 생각되었다. 한편 발효에 의한 기능성은 항산화효과를 제외한 간세포보호 및 ${\alpha}-Glucosidase$, ${\alpha}-Amylase$ 저해활성은 전체적으로 소폭 향상에 그쳤다. 따라서 이러한 결과를 바탕으로 발효 등 다양한 가공방법이 개발되어, 향후 아이스플랜트의 소비촉진의 계기가 되기를 기대한다.

The ${\alpha}-glucosidase$ inhibitory and antioxidant effects of water chestnut (Trapa japonica Flerov.) were assessed to explore its possible use as an anti-diabetic agent. Methanol extracts of the fruit shell and meat of water chestnut were assayed for inhibitory activity against yeast ${\alpha}-glucosidase$ and 1,1-diphenyl-2-picrylhydrazyl (DPPH) radical scavenging activity. Effect of fruit shell extract on postprandial glucose response was assessed. Compared with fruit meat, shell extract showed stronger inhibition against ${\alpha}-glucosidase$ with an $IC_{50}$ of 273 ${\mu}g/mL$. Oral administration of fruit shell extract (500 mg/kg) significantly lowered the postprandial area under the glucose response curve to starch (1 g/kg) in streptozotocin (STZ)-induced diabetic rats (p<0.01). Compared with fruit meat, shell extract showed stronger scavenging activity against DPPH, with an $IC_{50}$ of 27.1 ${\mu}g/mL$. The results indicate that the fruit shell of water chestnut was effective in controlling postprandial hyperglycemia and exerted an antioxidant effect. Therefore, water chestnut may be useful in treating diabetes.

Interstitial deletions involving the chromosome band 15q22q24 are very rare and only nine cases have been previously reported. Here, we report on a 12-day-old patient with a de novo 15q22q23 interstitial deletion. He was born by elective cesarean section with a birth weight of 3,120 g at 41.3-week gestation. He presented with hypotonia, sensory and neural hearing loss, dysmorphism with frontal bossing, flat nasal bridge, microretrognathia with normal palate and uvula, thin upper lip in an inverted V-shape, a midline sacral dimple, severe calcanovalgus at admission, and severe global developmental delay at 18 months of age. Fluorescence in situ hybridization findings confirmed that the deleted regions contained at least 15q22. The chromosome analysis revealed a karyotype of 46,XY,del(15) (q22q23). Parental chromosome analysis was performed and results were normal. After reviewing the limited literature on interstitial 15q deletions, we believe that the presented case is the first description of mapping of an interstitial deletion involving the chromosome 15q22q23 segment in Korea. This report adds to the knowledge of the clinical phenotype associated with the 15q22q23 deletion.

To develop a promoter capable of driving transgene expression in non-model fish, we identified and characterized the muscle-specific alpha-actin gene in olive flounder, Paralichthys olivaceus (PoACTC1). The regulatory region of PoACTC1 includes putative regulatory elements such as a TATA box, two MyoD binding sites, three CArG boxes, and a CCAAT box. Microinjection experiments demonstrated that the regulatory region of PoACTC1, covering from -2,126 bp to +751 bp, just prior to the start codon, drove the expression of red fluorescent protein in developing zebrafish embryos and hatching olive flounder. These results suggest that the regulatory region of PoACTC1 may be useful in developing a promoter for biotechnological applications such as transgene expression in olive flounder.
