항암 효과와 항산화 기능을 가지는 것으로 알려진 lycopene은 심혈관에서의 기능이 현재까지 잘 알려져 있지 않다. 본 연구에서는 lycopene의 심혈관 기능을 알기 위해 혈관내피세포를 이용해 다양한 세포실험을 수행하였다. 그 결과, lycopene은 내피세포의 성장 및 이동을 촉진하였으나 세포사멸에는 영향이 없었다. 또한, 백혈구의 혈관내피세포 부착을 억제하였고 내피세포 내 신호전달물질인 MAPK들의 활성을 촉발하였다. MAPK의 활성 억제제를 이용한 신호전달기전 연구실험 결과, ERK와 p38 MAPK의 활성은 세포성장에 관여하고, JNK의 활성은 세포이동에 관여함을 확인하였다. 종합하면, lycopene은 혈관내피세포의 신호전달 물질인 MAPK들를 통해 세포성장 및 이동을 촉진시키며, LPS에 의한 THP-1의 내피세포 부착을 억제 하는 등 혈관내피세포의 다양한 생리활성을 조절한다. Lycopene의 이러한 혈관내피세포 기능들은 lycopene이 혈관질환 치료제로 응용될 가능성이 있음을 의미한다.

The purpose of this study was to investigate the quality characteristics of tomato sauce, which is widely used in Western cuisine, according to tomato variety. The plum tomato sauce treatment had the highest pH at 4.13 while sauces made with Seo gwang and Young gwang tomatoes exhibited the lowest pH level of 4.07 (p<0.05). Sweetness was highest in the plum tomato sauce at $9.80^{\circ}$Brix. This might have been due to the fact that the plum tomato variety was the sweetest among the different tomatoes. There were no significant differences among the treatments in terms of reducing sugars, salinity, or viscosity. A color difference analysis indicated that redness (a-value) was highest in the plum tomato sauce, which contained a high level of lycopene. Sensory evaluations were performed by 15 professional panelists with scoring tests for color, flavor, taste, aftertaste, viscosity, and overall acceptability. The plum tomato sauce received the best scores in every evaluation, except for viscosity. These comparative results will support the development of better quality tomato sauce using plum tomatoes.

A variety of microorganisms in rhizosphere affect plant health by plant growth promotion, mitigation of abiotic stresses as well as protection from pathogen attacks. In our previous study, we selected a bacterium, Bacillus mesonae H20-5, for alleviation of salinity stress in tomato plants. In this study, we verified the effect of a liquid formulation of B. mesonae H20-5 (TP-H20-5) on fruit production and phytochemical accumulation including lycopene and polyphenol in cherry tomato and strawberry fruits in on-farm tests of protected cultivation under salinity stress. When vegetables including tomato, cherry tomato, strawberry, and cucumber were treated with TP-H20-5 by irrigated systems, final marketable yields were increased by 21.4% (cherry tomato), 9.3% (ripen tomato), 120.6% (strawberry), and 14.5% (cucumber) compared to untreated control. Moreover, treatment of TP-H20-5 was showed increase of phytochemicals such as lycopene and total polyphenol compared to untreated control in cherry tomato and strawberry. Therefore, these results indicated that a formulant of B. mesonae H20-5 can be used as a potential biofertilizer for increasing fruit production and quality.

Background: Red-fleshed sweet orange juice (ROJ) comes from a new variety of citrus cultivated in Brazil that contains high levels of ${\beta}$-carotene and lycopene, and similar amounts of hesperidin (HSP) and nutrients, equivalently to blond orange juice (BOJ). Such bioactive compounds are associated with chemopreventive actions in several cancer cell lines. The purpose of this study was to examine the cytotoxicity, cell cycle, apoptosis, and cytokine secretion after BOJ, ROJ, and HSP treatment of a novel T acute lymphoblastic leukemia cell line, Loucy. Materials and Methods: Loucy cells were incubated for 24-h with BOJ, ROJ, and HSP, and the viability was measured using trypan blue. Cell cycling and apoptosis were assessed by propidium iodide (PI) and annexin V-FITC/PI flow cytometry, respectively. Secretion of cytokines $IL-1{\alpha}$, $IL1-{\beta}$, IL-2, IL-4, IL-6, IL-10, IL-17A, $IFN{\gamma}$, $TNF{\alpha}$, $TGF{\beta}$, $MIP{\alpha}$, and $MIP{\beta}$ was determined by ELISA array. Results: BOJ and ROJ treatments promoted Loucy cell cytotoxicity. Additionally, BOJ induced cell cycle arrest in the G0/G1 phase, and decreased the cell accumulation in the G2/M. ROJ decreased only the G0/G1 fraction, while HSP did not change the cell cycle. BOJ led to apoptosis in a different fashion of ROJ, while the first treatment induced apoptosis by increase of late apoptosis and primary necrotic fractions, the second increased early and late apoptosis, and primary necrotic fraction compared to positive controls. HSP had no effect on apoptosis. IL-6 and IL-10 were abrogated by all treatments. Conclusions: Taking together, these results suggest potential chemopreventive effects of BOJ and ROJ on Loucy cells.

수박(Citrullus lanatus)은 전세계에서 경제적으로 중요한 채소작물이며, 라이코펜과 시트룰린과 같은 기능성 물질을 함유하고 있다. Didymella bryoniae 병원균에 의해 발생하는 덩굴마름병은 수박 재배에서 가장 피해를 많이 주는 병해 중에 하나이다. 단일염기다형성(SNP)은 한 개 염기에 관해 개체 간에 발생하는 유전적 변이로서 유전자 연관 지도를 작성하는 것과 원예적 형질 및 병저항성에 연관된 분자표지를 개발하는 데 자주 사용된다. 본 연구에서는 수박에서 모친과 부친의 차세대 염기서열 재분석(next generation resequencing)을 통해 SNP 분자표지를 선발하였다. 식물재료는 C. lanatus '920533'(모친, 감수성)과 C. amarus 'PI 189225'(부친, 저항성) 및 이들의 $F_1$, $F_2$ 개체를 이용하였다. NGS 분석 결과, '920533'과 'PI 189225'에서 각각 13.6 Gbp와 13.1 Gbp의 염기서열을 얻었다. '920533'과 'PI 189225' 간의 SNP 수는 609만 개였고, 그 중 HRM 프라이머로 디자인이 가능한 SNP의 수는 354,860개였다. 그 중에 HRM 분석을 위한 330개 프라이머 쌍이 디자인되었다. 결과적으로 HRM 분석을 통해 총 61개의 HRM 분자표지를 개발하였다. 이번 연구의 결과는 SNP 기반의 유전자지도 작성에 이용될 수 있으며 덩굴마름병 저항성과 연관된 양적 형질 유전자좌(QTL) 분석에 활용될 수 있을 것이다.
