Objective: Our research was to discuss effects and mechanism of lncRNA TUG1 in NSCLC by vitro study. Methods: A549 and H1299 cells were divided into NC, pcDNA 3.1 and lncRNA TUG1 groups. Measuring cell proliferation using CCK-8 assay, cell apoptosis by flow cytometry, invasion cell number by transwell and wound healing rate by wound healing assay. Relative gene and protein expressions by RT-qPCR and WB assay. Results: Compared with NC group, the cell proliferation rate, invasion cell number and wound healing rate were significantly depressed in A549 and H1299 cell lines (P < 0.001, respectively). By RT-qPCR and WB assay, lncRNA TUG1 gene expression were significantly increased (P < 0.001, respectively); E-cadherin gene and protein expression were significantly up-regulation, and N-cadherin and Vimentin gene and protein expressions were significantly depressed compared with those of NC group in A549 and H1299 cell lines (P < 0.001, respectively). Conclusion: lncRNA TUG1 had effects to suppress NSCLC cell biological activities by regulation EMT relative gene and proteins expression in vivo study.

Objective: The purpose of our study was to evaluate Enhancement Mechanism of Dihydromyricetin (DMY) on the Inhibitory Role of Cisplatin Towards Breast Cancer Cell Activity. Materials and Methods: The MCF-7 were divided into NC, DMY, Cis and DMY+Cis groups. Using relative methods (MTT, TUNEL, Transwell, flow cytometry and wound healing) to evaluate MCF-7 cell biological activities including cell viability, apoptosis, invasion cell number and wound healing rate. The relative proteins expressions including FOXO-1, Noxa, Bim, Cyto C, Caspase-3, Caspase-9 and Apaf-1 were evaluated by WB assay. Results: MCF-7 cell viability, invasion cell number and wound healing rates were significantly depressed and apoptosis rate were significantly increased in DMY, Cis and DMY+Cis groups (P < 0.01, respectively). Compared with Cis group, cell viability, invasion cell number and wound healing rates were significantly depressed and apoptosis rate were significantly increased in DMY+Cis group (P < 0.05, respectively). Conclusion: Dihydromyricetin can effectively enhance the inhibitory effect of cisplatin on breast cancer cells.

<sec> <title>Objective:</title> The purpose of this research is to explore the influences of thymosin β4 (Tβ4) in deepsecond-degree scald wound healing of rat skin and its relationship with Wnt/β-catenin pathway. </sec> <sec> <title>Methods:</title> Deep second-degree scalded model rats were prepared and divided into normal saline (NS) treatment group, Tβ4 treatment group and FH535 inhibitor group. Then, the concentrations of inflammatory factors in the rats were monitored via adopting the correlated TNF-α and IL-1β ELISA kits. In the meantime, the wound healing rate was analyzed via photography. Subsequently, the qRTPCR procedure was wielded to determine Wnt1 and β-catenin expression in wound tissues, and the degree of wound tissue injury was examined via hematoxylin and eosin (HE) staining. Finally, Western blotting (WB) was adopted to assess Wnt/β-catenin pathway-associated protein levels. </sec> <sec> <title>Results:</title> Releasing amount of TNF-α and IL-1β were conspicuously up-regulated after scalding (p <0.01), and Wnt1 and β-catenin expression at molecular transcription level was also significantly raised (p < 0.01). Besides, treatment with 18 μg of Tβ4 significantly increased the wound healing rate of scalded rats (p < 0.01). In addition, Tβ4 treatment significantly promoted wound healing (p < 0.01) and increased the Wnt1 and β-catenin expression levels (p < 0.01). Moreover, FH535 significantly restrained the Wnt/β-catenin pathway-correlated protein levels (p < 0.01) and wound healing. </sec> <sec> <title>Conclusion:</title> Tβ4 can promote scald wound healing in rats and may play a role via evoking Wnt/β-catenin pathway activation. </sec>

Abstract Plant-derived products can assist in the healing process of dermal wounds. It has been demonstrated that Hancornia speciosa latex present angiogenic, osteogenic, anti-inflammatory, and antioxidant activities. Then, it could contribute to the wound healing process. However, natural products in contact with skin may cause dermatitis. The objective of this work was to evaluate the allergic and irritant potential of H. speciosa serum fraction latex using in vitro assays. The obtained results showed that the H. speciosa serum fraction latex has a slightly irritant potential and is not cytotoxic neither allergenic for human cells. Moreover, we identified a remarkable low amount of proteins in this material in comparison to Hevea brasiliensis latex. This result could explain the non-allergenic potential of H. speciosa serum fraction latex because proteins present in latex are the main responsible for allergy. This biomaterial could be used as a non-allergenic source for development of new medicines.
