Identification and Expression Analysis of Gene in Bitter Gourd ().

Background: Lipoxygenases (LOXs) are key enzymes in the unsaturated fatty acid oxidation reaction pathway and play an important regulatory role in the synthesis of fruit aroma volatiles.

Methods: gene family members were identified in the whole genome database of bitter gourd and analyzed bioinformatically. An RT-qPCR was used to analyze the expression differences in different tissues.

Effect of Nickel Ions on the Physiological and Transcriptional Responses to Carbon and Nitrogen Metabolism in Tomato Roots under Low Nitrogen Levels.

Nickel (Ni) is an essential trace element for plant growth and a component of the plant body that has many different functions in plants. Although it has been confirmed that nickel ions (Ni) havea certain regulatory effect on nitrogen (N) metabolism, there are not enough data to prove whether exogenous Ni can increase the carbon (C) and N metabolism in the roots of tomato seedlingsunder low-nitrogen (LN) conditions. Therefore, through the present experiment, we revealed the key mechanism of Ni-mediated tomato root tolerance to LN levels.

The reference genome and full-length transcriptome of pakchoi provide insights into cuticle formation and heat adaption.

includes various vegetables with high economic value. Among them, green petiole type pakchoi ( ssp. ) is one of the major vegetables grown in southern China.

Piriformospora indica colonization increases the growth, development, and herbivory resistance of sweet potato (Ipomoea batatas L.).

Piriformospora indica symbiosis promoted the growth and photosynthesis, and simultaneously enhanced the resistance against insect herbivory by regulating sporamin-dependent defense in sweet potato. Piriformospora indica (P. indica), a versatile endophytic fungus, promotes the growth and confers resistance against multiple stresses by root colonization in plant hosts.

[Cloning, sequencing of G3PD gene from Brugia malayi and prediction of B cell epitopes in its amino acid sequence].

Specific primers were designed and synthesized based on the reported glyceraldehyde-3-phosphate dehydrogenase (BmG3PD) gene of Brugia malayi (GenBank Accession No. U18137). Total RNA was extracted from Brugia malayi and its BmG3PD gene was amplified by reverse transcription-polymerase chain reaction (RT-PCR).

[Cloning and eukaryotic expression of the gene encoding myosin from Brugia malayi].

Total RNA was extracted from periodic microfilariae of Brugia malayi and its myosin partial gene (Bm-M55) was amplified by RT-PCR. The PCR product was cloned and then subcloned into pcDNA3.1 (+)vector.

[Construction of eukaryotic expression plasmids with paramyosin gene of periodic Brugia malayi].

Total RNA was extracted from periodic Brugia malayi Specific primers were designed on the basis of known sequences of paramyosin gene from B. malayi (BmPmy). The desired gene was amplified by PCR technique from cDNA.

Enhanced transfection efficiency of a systemically delivered tumor-targeting immunolipoplex by inclusion of a pH-sensitive histidylated oligolysine peptide.

Successful cancer gene therapy depends on the development of non-toxic, efficient, tumor cell- specific systemic gene delivery systems. Our laboratory has developed a systemically administered, ligand-liposome complex that can effectively and preferentially deliver its therapeutic payload to both primary and metastatic tumors. To further improve the transfection efficiency of this targeting complex, a synthetic pH-sensitive histidylated oligolysine K[K(H)KKK]5-K(H)KKC (HoKC), designed to aid in endosomal escape and condensation of DNA, was included in the complex.

Systemic tumor-targeted gene delivery by anti-transferrin receptor scFv-immunoliposomes.

An ideal therapeutic for cancer would be one that selectively targets to tumor cells, is nontoxic to normal cells, and that could be systemically delivered, thereby reaching metastases as well as primary tumor. Immunoliposomes directed by monoclonal antibody or its fragments are promising vehicles for tumor-targeted drug delivery. However, there is currently very limited data on gene delivery using these vehicles.

A novel secreted splice variant of vascular endothelial cell growth inhibitor.

Vascular endothelial cell growth inhibitor (VEGI), a member of the tumor necrosis factor (TNF) family, is an endothelial cell-specific inhibitor of angiogenesis. Overexpression by cancer cells of a secretable VEGI fusion protein resulted in abrogation of xenograft tumor progression, but overexpression of full-length VEGI was completely without effect. This finding indicates that secretion is essential for VEGI action.

Self-assembly of a virus-mimicking nanostructure system for efficient tumor-targeted gene delivery.

Molecular therapy, including gene therapy, is a promising strategy for the treatment of human disease. However, delivery of molecular therapeutics efficiently and specifically to the target tissue remains a significant challenge. A human transferrin (Tf)-targeted cationic liposome-DNA complex, Tf-lipoplex, has shown high gene transfer efficiency and efficacy with human head and neck cancer in vitro and in vivo (Xu, L.
