The inheritance of leaf and heading-related traits in Chinese cabbage (Brassica rapa ssp. pekinensis) are poorly understood since only a handful of studies of these traits are available till date. In this study, QTL mapping was done for seven leaf and heading related traits that includes gross weight, number of non-wrapper leaves, head weight, head length, head width,head length/head width ratio, and the number of head-forming leaves in 139 F3 families derived from a cross between two diverse Chinese cabbage lines, ‘501’ with small head and ‘601’ with large head. A total of 27 QTL spread over the nine linkage groups were identified for seven leaf and head-related traits, many of which showed major effects clustered in A2, A4,A6, and A8. The results provided a better understanding of the genetic factors controlling leaf and head-related traits in Chinese cabbage.

<P><I>Brassica rapa</I> plants are highly important as vegetables, sources of oilseeds and fodder crop. Here, we developed 450 unigene derived microsatellite (UGMS) markers in <I>B. rapa</I> using unigenes downloaded from the National Center for Biotechnology Information database. Of the 450 UGMS primer pairs, 428 (95.1%) produced repeatable and reliable amplifications of expected size in at least one parental line of <I>B. rapa</I>, and 70 UGMS markers gave 72 polymorphic loci between the two contrasting parental lines. Cross-species transferability analysis of these 70 polymorphic UGMS markers in five other cultivated <I>Brassica</I> species showed varying transferability rates ranging from 82.9% in <I>B. nigra</I> to 97.1% in <I>B. juncea</I> and <I>B. napus</I>, and overall 53 UGMS markers amplified targets in all five species. The <I>B. rapa</I> linkage map was constructed using the 72 UGMS polymorphic loci and 154 previously developed SSRs. The newly developed UGMS markers and linkage map in this study would help in future studies to better understand the organization and evolution of <I>Brassica</I> genomes with respect to unigenes, in addition to mapping, tagging and cloning of economically important trait QTL/gene(s) and marker-assisted breeding in <I>Brassica</I> crops.</P>

WNT signaling plays an important role in cardiac development, but abnormal activity is often associated with cardiac hypertrophy, myocardial infarction, remodeling, and heart failure. The effect of WNT signaling on regulation of atrial natriuretic peptide (ANP) secretion is unclear. Therefore, the purpose of this study was to investigate the effect of Wnt agonist 1 (Wnta1) on ANP secretion and mechanical dynamics in beating rat atria. Wnta1 treatment significantly increased atrial ANP secretion and pulse pressure; these effects were blocked by U73122, an antagonist of phospholipase C. U73122 also abolished the effects of Wnta1-mediated upregulation of protein kinase C (PKC) β and γ expression, and the PKC antagonist Go 6983 eliminated Wnta1-induced secretion of ANP. In addition, Wnta1 upregulated levels of phospho-transforming growth factor-β activated kinase 1 (p-TAK1), TAK1 banding 1 (TAB1) and phospho-activating transcription factor 2 (p-ATF2); these effects were blocked by both U73122 and Go 6983. Wnta1-induced ATF2 was abrogated by inhibition of TAK1. Furthermore, Wnta1 upregulated the expression of T cell factor (TCF) 3, TCF4, and lymphoid enhancer factor 1 (LEF1), and these effects were blocked by U73122 and Go 6983. Tak1 inhibition abolished the Wnta1-induced expression of TCF3, TCF4, and LEF1 and Wnta1-mediated ANP secretion and changes in mechanical dynamics. These results suggest that Wnta1 increased the secretion of ANP and mechanical dynamics in beating rat atria by activation of PKC–TAK1–ATF2–TCF3/LEF1 and TCF4/LEF1 signaling mainly via the WNT/Ca2+ pathway. It is also suggested that WNT–ANP signaling is implicated in cardiac physiology and pathophysiology.

This study explored an integrated strategy for extraction and preparative separation of four anthocyaninsfrom Ribes nigrum L. using DES-based microwave assisted extraction andflash chromatography. Theextraction yield of anthocyanins reached 2.03 mg/g after optimization. An efficient preparativeseparation process of four main anthocyanins by macroporous resin andflash chromatography wasestablished afterwards. The yields of D3G, D3R, C3G and C3R reached 0.32 mg/g, 0.47 mg/g, 0.18 mg/g and0.43 mg/g with the purities of more than 95%, respectively. The developed procedure represents anefficient and convenient alternative for the systematic utilization of natural products from plantmaterials.

Purpose Colon cancer-associated transcript 1 (CCAT1) was identified as an oncogenic long non-coding RNA (lncRNA) in a variety of cancers. However, there was a lack of understanding of the mechanism by which CCAT1 conferred cisplatin (also known as DDP) resistance in ovarian cancer cells. Materials and Methods Cell viability of A2780, SKOV3, A2780/DDP, and SKOV3/DDP cells upon cisplatin treatment was monitored by MTT assay. Quantitative reverse transcription polymerase chain reaction (qRT-PCR) detected the expression levels of CCAT1 and miR-454. The effect of sh-CCAT1 on cisplatin response was investigated in xenografts study. Bioinformatic analysis, luciferase reporter assay and qRT-PCR were conducted to validate the direct interaction among CCAT1, miR-454, and survivin. Apoptosis was determined by flow cytometry after dual staining of Annexin-V-FITC/propidium iodide, and the expression of apoptosis-related proteins Bcl-2, Bax and survivin were detected by qRT-PCR and Western blotting. Xenograft study was conducted to monitor in vivo tumor formation. Results CCAT1 was highly expressed in cisplatin-resistant ovarian cancer cell line A2780/DDP and SKOV3/DDP. Knockdown of CCAT1 restored sensitivity to cisplatin in vitro and in vivo. Our data revealed that silencing of CCAT1 promoted cisplatin-induced apoptosis via modulating the expression of pro- or anti-apoptotic proteins Bax, Bcl-2, and survivin. CCAT1 directly interacted with miR-454, and miR-454 overexpression potentiated cisplatin-induced apoptosis. Survivin was identified as a functional target of miR-454, restoration of survivin attenuated the effect of miR-454 on cisplatin response. In addition, miR-454 inhibitor or overexpression of survivin was found to abolish sh-CCAT1–induced apoptosis upon cisplatin treatment. Conclusion CCAT1/miR-454/survivin axis conferred cisplatin resistance in ovarian cancer cells.

With CO2 and N2 as the pressure media, the effects of the moderate pressure (0.1-1.0MPa) and the holding time on the conductivities of the cell suspension of Saccharomyces cerevisiae CICC1447 and Saccharomyces cerevisiae CICC1339, as well as the absorbances of the supernatant (after centrifuged) at 280 nm (A280) and 260 nm (A260) were determined. The membrane permeability of Saccharomyces cerevisiae CICC1447 increased significantly and the cell leakage was aggravated with the pressure increase. For Saccharomyces cerevisiae CICC1339, the conductivity of the cell suspension, A280 and A260 of the supernatant fluctuated with the pressure increase; as a whole, they increased with pressure. Different from high pressure, a moderate pressure not only remarkably improved the permeability of the yeast cell membrane, but also kept yeast cell viability; moreover, the integrity of the yeast cell membrane could be maintained.

Adenocarcinoma of lung has high incidence and a poor prognosis, woith chemotherapy as the main therapeutic tool, most commonly with cisplatin. However, chemotherapy resistance develops in the majority of patients during clinic treatment. Mechanisms of resistance are complex and still unclear. Although annexin play important roles in various tumor resistance mechanisms, their actions in cisplatin-resistant lung adenocarcinoma remain unclear. Preliminary studies by our group found that in cisplatin-resistant lung cancer A549 cells and lung adenocarcinoma tissues, both mRNA and protein expression of annexins A1, A2 and A3 is increased. Using a library of annexin A1, A2 and A3 targeting combined molecules already established by ourselves we found that specific targeting decreased cisplatin-resistance. Taken together, the underlined effects of annexins A1, A2 and A3 on drug resistance and suggest molecular mechanisms in cisplatin-resistant A549 cells both in vivo and in vitro. Furthermore, the study points to improved research on occurrence and development of lung adenocarcinoma, with provision of effective targets and programmes for lung adenocarcinoma therapy in the clinic.

Cholesterol-lowering effect of lactic acid bacteria is well-known. In the present study, nine cholesterol-lowering Lactobacillus strains from Chinese traditional cheese, pickle, and yoghurt were screened and characterized for their potential use. The microbial contents of all strains significantly decreased at pH 1.5; however, the residual counts of Lactobacillus casei subsp. casei GL-03, L. plantarum ZP-Z, L. plantarum ZP-05, and L. brevis ZP-04 were more than $10^7CFU/mL$ after incubation for 6 h. All nine strains of Lactobacillus indicated good tolerance to bile at concentration less than 0.2% after incubation for 2 to 6 h. L. plantarum ZP-W had maximum hydrophobicity towards xylene, whereas GL-03 strain possessed maximum hydrophobicity for both hexadecane and octane. ZP-05 strain had more effective inhibitory activity against both Staphylococcus aureus and Bacillus subtilis than other eight strains. Furthermore, GL-03 strain significantly reduced cholesterol TC and TG levels in hyperlipidemia mice fed high-cholesterol diet. The growth of GL-03 strain was promoted by five kinds of Chinese herbal medicines, and the Chinese hawthorn at concentration of 0.0125% showed the highest promoting effect. These results suggest that L. casei subsp. casei GL-03 may be effective as a probiotic with cholesterol-lowering activities.
