Single nucleotide polymorphisms of MIR-149 gene rs2292832 contributes to the risk of hepatocellular carcinoma, but not overall cancer: a meta-analysis.

Introduction: Single nucleotide polymorphism in miRNAs can alter its expression, thus can lead to the development of cancers. Numerous studies have explored the association between MIR-149 gene rs2292832 polymorphism and hepatocellular carcinoma (HCC) risk, but the results remains inconsistent. So, we performed this pooled analyses in order to get a precise result.

Inhibiting effect of Endostar combined with ginsenoside Rg3 on breast cancer tumor growth in tumor-bearing mice.

Objective: To study the inhibiting effect of Endostar combined with ginsenoside Rg3 on breast cancer tumor growth in tumor-bearing mice.

Methods: Female mice were selected as experimental animals, and breast cancer tumor-bearing mouse models were established and then divided into groups A, B, C and D that respectively received saline, recombinant human endostatin, ginsenosides Rg3 and recombinant human endostatin combined with Rg3 intervention; 7 d, 14 d and 21 d after intervention, tumor tissue volume was measured; 21 d after intervention, mice were killed, tumor tissue was collected, and mRNA contents of angiogenesis molecules, invasion molecules, autophagy marker molecules and autophagy signaling pathway molecules were detected.

Results: At 7 d, 14 d and 21 d after intervention, tumor tissue volume of groups B, C and D was lower than that of group A, and tumor tissue volume of group D was lower than that of groups B and C; mRNA contents of VEGFA, VEGFB, VEGFC, MMP2, MMP9, p62, mTOR, PI3K, Akt, JNK and Beclin-1 in tumor tissue of groups B, C and D were significantly lower than those of group A, and LC3-II/LC3-I was significantly higher than that of group A; mRNA contents of VEGFA, VEGFB, VEGFC, MMP2, MMP9, p62, mTOR, PI3K, Akt, JNK and Beclin-1 in tumor tissue of group D were significantly lower than those of groups B and C, and LC3-II/LC3-I was higher than that of groups B and C.
