[Transcriptome-wide identification and expression pattern analysis for Dof gene family in Panax ginseng from Jilin].

Dof(DNA binding with one finger), a unique class of transcription factors in plants, play an important role in seed development, tissue differentiation, and metabolic regulation. To identify the number and function of Dof gene family members in Panax ginseng, this study identified the members of Dof gene family in P. ginseng and systematically analyzed their structures, evolution, functional differentiation, expression patterns, and interactions using bioinformatics methods at the transcriptome level.

Circulating serum exosomal miR-20b-5p and miR-3187-5p as efficient diagnostic biomarkers for early-stage non-small cell lung cancer.

The high mortality of non-small cell lung cancer (NSCLC) is mainly because the cancer has progressed to a more advanced stage before diagnosis. If NSCLC can be diagnosed at early stages, especially stage 0 or I, the overall survival rate will be largely improved by definitive treatment such as lobectomy. We herein validated two novel circulating serum ExmiRs as diagnostic biomarkers for early-stage NSCLC to fulfill the unmet medical need.

[Expression of saponin biosynthesis related genes in different tissues of ].

The relationship between saponin content of in different parts of the organization and expression of ginsenoside biosynthesis related gene was obtained by the correlation analysis between saponin content and gene expression. The 14 tissue parts of were studied, six saponins in Samples (ginsenoside Rg₁, Re, Rb₁, Rc, Rb₂ and Rd), group saponins and total saponins were determined by high performance liquid chromatography and vanillin-sulfuric acid colorimetric method. Simultaneously, the expression levels of 7 ginsenoside biosynthesis related genes ( and ) in different tissues of were determined by Real-time fluorescence quantitative PCR.

[Research achievements on ginsenosides biosynthesis from Panax ginseng].

Panax ginseng is one of the famous rare medicinal herbs, and ginsenosides are the main active ingredient of ginseng is ginsenoside.They can be divided into three chemotypes: oleanane type, protopanaxadiol (PPD) type and the protopanaxatriol (PPT)type. Ginsenosides possess anti-thrombotic, anti-fatigue, anti-aging, cancer control, strengthening the immune system and many other effects.

[Correlation of gene expression related to amount of ginseng saponin in 15 tissues and 6 kinds of ginseng saponin biosynthesis].

Fifteen tissues of 4-year-old fruit repining stage Jilin ginseng were chosen as materials, six kinds of monomer saponins (ginsenosides Rg1, Re, Rb1, Rc, Rb2 and Rd) content in 15 tissues was measured by HPLC and vanillin-sulfuric acid method. The relative expression of FPS, SQS, SQE, OSC, β-AS and P450 genes in 15 tissues was analyzed by real-time PCR. The correlations between ginseng saponin content in 15 tissues of Jilin ginseng and biosynthetic pathway -related genes were obtained.

[Fermentation transformed ginsenoside by Lactobacillus plantarum].

Objective: To explore ginseng fermentation process by Lactobacillus plantarum, and to make part of total saponins transformed into more reactive ginsenoside Rd.

Method: Microbial fermentation was carried out by still dark culture. Total saponins were extracted by Soxhlet extraction, and determined by UV visible spectrophotometry with colours reaction by vanillin-sulfuric acid.

The complete mitochondrial genome of Diqing wild boar (Sus verrucosus breed Diqing wild boar).

In the present study, the complete mitochondrial genome sequence of the diqing wild boar (Sus verrucosus breed diqing wild boar) was reported for the first time. The total length of the mitogenome was 16,506 bp. It contained the typical structure, including two ribosomal RNA genes, 13 protein-coding genes, 22 transfer RNA genes and one non-coding control region (D-loop region) as that of most other wild boars.
