Background : Nowadays obesity has increased dramatically in developed countries which lead various metabolic disorders such as type 2 diabetes, hypertension, cancer, and the risk of stroke. Thus, looking forward a new chemical entity from natural sources which have a strong potential of anti-lipid regulation activity. Recently, protein based nanomedicine offers a new approach to treat a number of diseases including metabolic disorder such as obesity. In this study we evaluated the anti-lipid regulation effect of nano-carrier Bovine serum albumin and Mesoporous silica (MSNPs) conjugated ginsenoside F1 in 3T3-L1adipocytes and HepG2 hepatocytes. Methods and Results : BSA incorporated drugs has been shown to protect the drug degredation as well as improvement bioavalilability. To assess the anti- adipogenic effect of BSA-F1 and MSNPs-F1 cell viability was investigated in different time point of cell cycle growth and the intracellular lipid accumulation was evaluated in mature adipocytes and hepatocytes by Oil red staining assay. In addition, transcriptional gene regulation was quantified by the real time PCR for targeting adipogenic genes such as PPARγ, STAT3, CEBPα, ap2 and aP2 as well as hepatogenic genes such as ACC, AMPK, FAS and PPARα. Moreover, protein expression was evaluated by immunoblotting assay. Conclusion : Altogether, the above results were confirmed that BSA-F1 at dose 25 μM exhibited the anti-adipogenesis effect by downregulating the major transcriptional factors PPAR γ/STAT3 in signalling in 3T3-L1 mature adipocytes and upregulated the fatty acid oxidative AMPK signaling in fatty acid induced HepG2 hepatocytes.

For developing molecular markers linked to white rust resistance in chrysanthemum, RAPD and AFLP were carried out in ‘Puma White’ x ‘Dancer’ mapping population through Bulked Segregant Analysis (BSA) methods. 10 resistant and 10 susceptible individuals were selected and bulked. And then, these bulks were screened using 280 RAPD primers (10 mer) with two parents. As a result of BSA-RAPD, 25 Dancer/R-bulk specific bands in 21 primers and 22 Puma White/S-bulk specific bands in 18 primers were selected. These resistant or susceptible specific bands were screened in 10 resistant and 10 susceptible individuals. Except OPI-13520, all bands were confirmed as false positive. OPI-13520 band presumed as closely linked marker to white rust disease resistance was tested in whole population. Among 187 progenies, just six off-springs did not correspond with phenotypic data. Based on expected phenotypic segregation ratios in the pseudo F1 progenies, it was assumed that a duplex type of white rust resistance in ‘Dancer’ (RRrrrr) were in combination with a duplex type of OPI-13520 marker. As a result of x2-test of independence between resistance gene and OPI-13520 marker, x2 score is 76.08 and probability is 2.13x10-16. And resistance gene and OPI-13520 marker were assumed to be linked in coupling phase. The value of recombination fraction obtained by successive trials and second derivative of log likelihood was 0.03832±0.0271.

Soybean is a major source of protein meal in the world. Kunitz trypsin inhibitor (KTI) protein is responsible for the inferior nutritional quality of unheated or incompletely heated soybean meal. The objective of this research was to identify RAPD markers linked to KTI protein allele using bulked segregant analysis. Cultivar Jinpumkong2 (TiTi) was crossed with C242 (titi, absence of KTI protein) and F. seeds were planted. The F1 . plants were grown in the greenhouse to produce F2 seeds. Each F2 seed from F1 . plants was analysed electrophoretically to determine the presence of the KTI protein band. The present and absent bulks contained twenty individuals each, which were selected on the basis of the KTI protein electrophoresis, respectively. Total 94 F2 individuals were constructed and 1,000 Operon random primers were used to identify RAPD primers linked to the Ti locus. The presence of KTI protein is dominant to the lack of a KTI protein and Kunitz trypsin inhibit protein band is controlled by a single locus. Four RAPD primers (OPAC12, OPAR15, OPO12, and OPC08) were linked to the Ti locus. RAPD primer OPO12 was linked to Ti locus, controlling kunitz trypsin inhibitor protein at a distance of 16.0 cM. This results may assist in study of developing fine map including Ti locus in soybean.
