Tumor angiogenesis plays an important role in tumor metastasis. In recent years, many studies found that erythropoietin-producing hepatocellular (Eph) receptor and its ligand Ephrin plays an important role in vascular remodeling and angiogenesis in early embryonic stage. The bi-directional signaling of Eph/Ephrin can modulate the morphology and function of tumor cells, and influence the angiogenesis of tumor, thus affecting the invasion and metastasis of tumor cells. The expression levels of Eph and Ephrin can be used as biomarkers to assess the malignant degree of tumor and predict the prognosis of cancer patients, which make the Eph/Ephrin signaling pathway become a potential target for cancer treatment.

Abstract: Objective　This paper aims to explore the effect of live attenuated varicella vaccine on the sensitivity of tuberculin skin test(TST), and to provide reference for tuberculin skin test in the future. Methods　TST and emergency varicella vaccine were administered to students in grade one of a high school in Wuxi, Jiangsu province, who had both TB and varicella cases. Independent-samples t test was used to analyze the mean diameter of induration of TST in day 0, day 83 and day 195. The retrospective cohort study was used to analyze the effect of live attenuated varicella vaccine on TST. 　　Results　The mean induration diameter of 45 students who participated in three TST tests on day 0, day 83 and day 195 were analyzed by independent sample t test. On day 0, there was a difference in the mean diameter of TST induration between the unvaccinated and vaccinated groups(1.630±2.837 vs 5.818±4.530) (t=-3.692, P=0.001). On day 83, there was no difference in the mean diameter of TST induration between the two groups(0.001±0.001 vs 0.114±0.533) (t=-1.000, P=0.329). On day 195, there was a difference in the mean diameter of TST induration between the two groups(1.913±3.774 vs 5.023±5.126) (t=-2.309, P=0.026). Moreover, the retrospective cohort study showed that the mean diameter of TST induration changed more significantly after inoculation with varicella vaccine, RR=6.071, 95%CI (1.667-22.116), P<0.05; After inoculation with varicella vaccine, the mean diameter of TST test did not change significantly from day 0 to day 195 with no statistical significance RR=3.474, 95%CI (0.333-36.240), P>0.05. Conclusions　Live attenuated varicella vaccine may temporarily affect the sensitivity of tuberculin skin test.

Traditional herbal medicines, Panax ginseng, Panax quinquefolium and Panax notoginseng, attract our attention for their extensive and powerful pharmacological activities. Ginsenosides are the main active constituents of these medicinal herbs. The related glycosyltransferases involved in ginsenoside biosynthesis are the key enzymes which catalyze the last important step. Modification of ginsenoside aglycones by glycosyltransferases produces the complexity and diversity of ginsenosides, which have more extensive pharmacological activity. At present, ginsenoside aglycones and compound K have been obtained by synthetic biology. As the last step of ginsenoside biosynthesis, glycosylation of ginsenoside aglycones has been studied intensively in recent years. This review summarizes the basic strategies and research advances in studies on glycosyltransferases involved in ginsenoside biosynthesis, which is expected to lay the theoretical foundation for the in-depth research of biosynthetic pathway of ginsenosides and their production by synthetic biology.

Lanosterol synthase is encoded by the erg7 gene and catalyzes the cyclization of 2, 3-oxidosqualene, which is a rate-limiting step of the inherent mevalonate (MVA)/ergosterol metabolic pathway in Saccharomyces cerevisiae. The intermediate 2, 3-oxidosqualene is also the precursor of triterpenoids. Therefore, the cyclization of 2, 3-oxidosqualene is the key branch point of ergosterol and triterpenoids biosynthesis. Down-regulation of 2, 3-oxidosqualene metabolic flux to ergosterol in S. cerevisiae may redirect the metabolic flux toward the triterpenoid synthetic pathway reconstructed by the synthetic biology approach. To construct erg7 knockout cassette harboring the loxP-Marker-loxP element, long primers were designed, which were homologous to the sequences of both erg7 ORF and plasmid pUG66. The cassette was transformed into diploid wild strain INVSc1 by LiAc/SS Carrier DNA/PEG method and then erg7 gene haploid deficient mutant was obtained by homologous recombination. The results of semiquantitative PCR and real-time quantitative PCR revealed that erg7 expression level in erg7 gene haploid deficient mutant is one time lower than that in wild strain. The results of TLC and HPLC showed that the ergosterol content in deficient mutant decreased to 42% of that in wild strain.

BmK AngM1 is a long-chain scorpion toxin purified from the venom of Buthus martensii Karsch. It has been reported to exhibit evident analgesic effect and low toxicity, and has the potential to be a novel analgesic drug. The BmKAngM1 gene was transformed into Pichiapastoris GS115. Mut+ and Mut(s) recombinant strains were screened by phenotype and Mut+ recombinant strains were used to detect BmK AngMl gene copy number in the real-time PCR. Expression of BmK AngM1 in the Mut+ recombinant strain was compared with that of the Mut(s) recombinant strain with the same single copy of BmK AngM1 gene under the same condition. The results indicated that the transcription level of BmK AngM1 gene in the Mut(s) recombinant strain was 2.7 fold of that in the Mut recombinant strain in the real-time PCR, and the expression of BmK AngM 1 in the Mut(s) recombinant strain was 1.5 fold of that in the Mut+ recombinant strain. Therefore, Mut(s) recombinant strain showed better ability to express BmK AngM1 than Mut+ recombinant strain.
