miR-214 interacted with vascular endothelial growth factor A (VEGFA) and B-cell CLL/lymphoma 2 (Bcl-2). VEGFA and Bcl-2, overexpressed in CSCC tissues and cells, were negatively correlated with miR-214. Moreover, VEGFA and Bcl-2 overexpression reversed the anti-tumor phenotypes of miR-214 on CSCC cells. miR-214 disrupted the Wnt/β-catenin pathway through VEGFA and Bcl-2 in the CSCC cells.

Our data demonstrates that miR-214 exerts a suppressing role in CSCC. The discovery of novel targets such as miR-214 and VEGFA/Bcl-2 may facilitate the development of therapeutic options.

Predicting RNA molecule interaction with the target protein could allow us to understand important cellular processes and design novel treatment therapies for various diseases. As non-coding RNAs do not have coding potential our knowledge about their functions is still limited. Therefore, RNA-binding proteins of non-coding RNAs regulating functions, viz. including cellular maturation, nuclear export and stability may play a very important role. Keeping in view of the need for refined methods to understand protein-RNA interactions, we have attempted a docking model to infer binding sites between lncRNA NONHSAT02007 and protein KIF13A for a rare disease phenotype that we are studying in our lab.

The most well-known, applicable and vastly studied member of the peroxidases family is horseradish peroxidase (HRP), especially the isoenzyme C (HRP C). HRP (primarily HRP C) is commercially available and applicable in biotechnology and diagnosis. Recently, a novel application of HRP has been introduced in cancer therapy as the combination of HRP with indole-3-acetic acid (IAA). The anticancer activity of HRP/IAA complex is through oxidation of IAA by HRP in hypoxic tumor condition, which leads to apoptosis and cancerous cell death. However, the molecular interaction of HRP/IAA has not been elucidated. Identifying the interaction of IAA with HRP would provide a better insight into its function and applications. In this study, molecular docking and molecular dynamics (MD) simulation were applied to determine the molecular interaction of the IAA/HRP complex. The docking study represented that IAA bound at the 'exposed' heme edge of the HRP enzyme, and the IAA entrance to the enzyme was situated at the carboxymethyl side-chain of the selected structure. Our computational results showed the HRP/IAA complex structure stability. While hydrogen bond formation with ARG38 and HIS42 stabilized the substrate, hydrophobic interactions with Phe68, Gly69, Leu138, Pro139, Pro141 and Phe179 contributed to IAA/HRP complex stability. The results can help to better understand peroxidase enzyme activity and would pave the way for future development of new therapeutics with improved anticancer efficacy. Communicated by Ramaswamy H.

This study aims to explore the clinical value of systemic chemotherapy combined with bronchoscopic seed implantation in advanced lung cancer treatment.

The study enrolled 253 patients with advanced lung cancer in Cangzhou People's Hospital from March 2018 to March 2020, and they were divided into test group and control group. Test group was given systemic chemotherapy combined with bronchoscopic seed implantation, while control group was given systemic chemotherapy. The objective response rate of tumor (ORR), disease control rate (DCR), serum tumor marker level, survival time and adverse reactions of 2 groups were compared.

After treatment, the levels of serum tumor markers including carcino-embryonic antigen, neuro-specific enolase, cytokeratin-19 and pro-gastrin-releasing peptide were markedly decreased in test group compared with those in control group (

< 0.05). Therein, the serum tumor marker level of non-small cell lung cancer (NSCLC) patients was significant decreased compared with that of sntation was superior to that of systemic chemotherapy, which is worthy of promoting in clinical practice.The theories of consciousness discussed by Doerig and colleagues tend to monolithically identify consciousness with some other phenomenon, process, or mechanism. But by treating consciousness as singular explanatory target, such theories will struggle to account for the diverse properties that conscious experiences exhibit. We propose that progress in consciousness science will best be achieved by elaborating systematic mappings between physical and biological mechanisms, and the functional and (crucially) phenomenological properties of consciousness. This means we need theories for consciousness science, perhaps more so than theories of consciousness. From this perspective, 'predictive processing' emerges as a highly promising candidate.The microRNA-200 (miR-200) family has been reported to be vital for the inhibition of epithelial-to-mesenchymal transition (EMT) in tumor cells. The miR-200 family represents a complex multi-factorial regulatory network which has not been well described in breast cancer. This study aimed to clarify the underlying regulatory association between IL-8 and miR-200 family in the process of EMT in breast cancer cell. In estrogen-receptor (ER) positive breast cancer cell line MCF-7, IL-8 overexpression cells were performed by lentivirus transfection as endogenous regulation with additional exogenous IL-8 stimulation. Transient overexpressions of miR-200 family were performed after endogenous or exogenous IL-8 overexpression in MCF-7 cells. IL-8 knockdown cells were constructed via siRNA and shRNA transfection in triple negative breast cancer cell line MDA-MB-231. N-cadherin, vimentin and ZEB2 were down-regulated and E-cadherin was up-regulated in IL-8 knockdown group compared with control group. GSK2110183 On the other hand, N-cadherin, vimentin and ZEB2 were up-regulated and E-cadherin was down-regulated in IL-8 overexpression group compared with control group.
