Influence of Ginkgo biloba extract on proliferation of ACC-2 cell, Survivin and TIP30 gene expression in adenoid cystic carcinoma of lacrimal gland / 中国中药杂志

Exploring the influence of extract of Ginkgo biloba (EGB) on the proliferation, apoptosis of ACC-2 cell in lacrimal adenoid cystic carcinoma and analyzing the influence of EGB on the gene expression of Survivin and TIP30 based on the levels of the gene and protein. ACC-2 cell in human with ACC of lacrimal gland disposed by EGB of different concentration was in vitro cultured. MTT method was used for cell proliferation detection. Annexin V/PI double-staining flow cytometer was used to detect cell apoptosis and cell cycle. Survivin and TIP30 gene expression together with protein expression were analyzed by RT-PCR and Western blotting. And it is indicated that EGB has inhibitory effect on the proliferation of ACC-2 cell in vitro. Furthermore, the dose-effect relationship was significant. Compared with the control group, it had statistical difference (P <0.01). The inhibitory concentration 50% (ICso) is 88 mg . L-1. By flow cytometer examination, it was indicated that EGB can gradually increase ACC-2 cell in G0-G1 stage and decrease it in G2-M and S stage. With the increase of dose, the apoptosis rate of ACC-2 cell obviously increased (P <0.05 or P <0.01). Both of the expression results of RT-PCR and Western hybrid proteins have showed that the concentration of EGB increased, it could be seen a significant decrease in Survivin gene expression (P <0.01). Meanwhile, the TIP30 gene expression got a significant increase. Therefore, EGB can effectively inhibit ACC-2 cell Survivin gene expression in human with adenoid cysistic carcinoma of larcrimal gland as well as promoting TIP30 gene expression, inducing the ACC-2 cell apoptosis and inhibiting tumor cell proliferation, which provided a certain theoretical and experimental basis for the application of Chinese herbal medicinal ingredient in the treatment of tumors.

Liver histopathological features influencing HBeAg seroconversion in patients with HBeAg-positive chronic hepatitis B responding to Peg-IFN treatment / 中华肝脏病杂志

<p><b>OBJECTIVE</b>To investigate the therapeutic efficiency of antiviral treatment with pegylated-interferon (Peg-IFN) for hepatitis B e antigen (HBeAg)-positive chronic hepatitis B (CHB) and to explore whether liver histopathological features or other factors influence the HBeAg seroconversion treatment response.</p><p><b>METHODS</b>Eighty HBeAg-positive CHB patients with diagnosis confirmed by liver puncture were treated with Peg-IFN(2a or 2b)body weight dose, once weekly). At treatment week 48, the rate of HBeAg seroconversion was determined and used to analyze the influence of liver histopathological features (liver biopsy assessment of: inflammation, graded G0 to G4; fibrosis stage, graded S0 to S4), sex, age, differential levels (pre-treatment baseline vs. week 48 post-treatment) of serum alanine transferase (ALT), and HBV DNA, by binary logistic analysis.</p><p><b>RESULTS</b>At week 48, the overall rate of HBeAg seroconversion was 30.0%. The rate of HBeAg seroconversion gradually advanced with increased liver inflammation (X2 = 8.435, P = 0.015): 9.09% of the 22 patients with G1; 31.58% of the 38 patients with G2; 47.30% of the 19 patients with G3; the one patient with G4. In contrast, the rate of HBeAg seroconversion showed a much weaker association with liver fibrosis (X2 = 5.917, P = 0.116). Only baseline HBeAg level, and no other baseline index, was significantly different between the patients who achieved HBeAg seroconversion and those who did not. Liver inflammation and baseline HBeAg level were identified as influencing factors of HbeAg seroconversion in response to Peg-IFN treatment.</p><p><b>CONCLUSION</b>Peg-IFN therapy induces a higher rate of HBeAg seroconversion in HBeAg-positive CHB patients with severe liver inflammation; histological analysis of pre-treatment liver biopsies may help to identify patients most likely to benefit from the antiviral regimen.</p>

Clinical significance of leukemia stem/progenitor cell related gene expression in acute leukemia / 中国实验血液学杂志

This study was aimed to detect the expression of leukemia stem/progenitor cell (LSPC) related genes (ABCB1, BMI-1, HOXB4) in the patients with acute leukemia, and to explore its clinical significance in acute leukemia. Bone marrow samples were collected from de novo acute leukemia patients (41 cases), patients with complete remission (CR, 16 cases) and the patients with non-malignant hematologic diseases (10 cases) respectively. And the expressions of ABCB1, BMI-1, HOXB4 genes were detected by comparative real-time quantitative PCR (RQ-PCR) with SYBR Green assay. The results showed that the expressions of ABCB1, BMI-1, HOXB4 were not detected in the patients with non-malignant hematologic diseases, but were higher (relative expressive level: 4.26 ± 2.26, 3.72 ± 1.91, 3.74 ± 2.38) in de novo acute leukemia patients and lower (relative expressive level: 2.14 ± 1.47, 2.07 ± 0.99, 1.47 ± 0.89) in the acute leukemia patients with CR (p < 0.05). The expressions of LSPC related genes were lower (relative expressive level: 1.77 ± 1.29, 2.09 ± 1.26, 1.78 ± 1.49) in the patients acquired CR/partial remission (PR) than those in the patients not acquired CR/PR (relative expressive level: 7.23 ± 1.78, 3.96 ± 0.92, 4.48 ± 2.57) (p < 0.01). Univariate analysis revealed that there were more cases with the expression of LSPC immunophenotype (CD34(+)CD38(-)CD96(+) and CD34(+)CD38(-)CD123(+)) and more hyperleukocytosis cases in patients with any higher expression of LSPC related gene (p < 0.05). Analysis of multiple parameters discovered larger significance (p < 0.01). It is concluded that there is a good relationship between LSPC related genes (ABCB1, BMI-1, HOXB4) and LSPC immunophenotype. The expression of LSPC-related genes is higher in de novo acute leukemia patients, and lower in patients acquired CR/PR. The patients with higher expressed LSPC-related genes display worse response to chemotherapy, lower CR/PR rate and higher leukocytosis, the analysis of multiple parameters may be a good method for assessing the therapeutic efficacy/prognosis of acute leukemia.

Associations of MYF5 gene polymorphisms with meat quality traits in different domestic pig (Sus scrofa) populations

The MYF5 gene is first inducibly expressed in muscle cell during embryonic muscle development and plays an important role in regulating the differentiation of skeletal muscle precursors. In this study we used PCR-RFLP to investigate two pig (Sus scrofa) populations (n = 302) for two MYF5 gene polymorphisms, a previously unreported novel Met-Leu shift single nucleotide polymorphism (SNP) MYF5/Hsp92II located on exon 1 and the previously identified intron 1 MYF5/HinfI SNP. Haplotype and association analysis showed that haplotypes of the two SNPs were significantly associated with drip loss rate (DLR, p < 0.05), water holding capacity (WHC, p < 0.05), biceps femoris meat color value (MCV2, p < 0.05), biceps femoris marbling score (MM2, p < 0.01), longissimus dorsi intramuscular fat percentage (IMF, p < 0.01) and longissimus dorsi Water moisture content (WM, p < 0.01) in the population 2. However, further studies are needed to confirm these preliminary results.
