Prognostic significance of epigenetic regulatory gene expression in patients with non-small-cell lung cancer.

In this study, we used public databases to investigate the prognostic significance of epigenetic regulatory gene expression in patients with non small-cell lung cancer (NSCLC). Oncomine database analysis showed that the mRNA levels of seven epigenetic regulatory genes, and , genes were significantly upregulated in NSCLC patients as compared to normal lung tissues. Functional enrichment analysis of these seven genes showed that the most enriched GO terms were DNA repair and rhythmic process, whereas, the most enriched KEGG pathway was lysine degradation pathway.

Identification of core genes for early diagnosis and the EMT modulation of ovarian serous cancer by bioinformatics perspective.

Ovarian serous carcinoma (OSC), as a common malignant tumor, poses a serious threat to women's health in that epithelial-mesenchymal transformation (EMT)-related modulation becomes heavily implicated in the invasion and progression of OSC. In this study, two core genes (BUB1B and NDC80) among the 16 hub genes have been identified to be involved in the molecular regulation of EMT and associated with the poor early survival of OSC at stages I+II. Through the Gene Regulatory Networks (GRN) analysis of 15 EMT regulators and core genes, it was revealed that TFAP2A and hsa-miR-655 could elaborately modulate EMT development of OSC.

Transcription-Related Dynamics from Immune Disability into Endogenous Innovation.

So far, thymus involution in adults is believed to be irreversible, and endogenous innovation for thymus-related immunodeficiency remains to be an intractable puzzle. With the expectation of addressing this dilemma, human ovarian surface epithelium (OSE) has been reengineered as epithelial-mesenchymal transition (EMT)-tridimensional-spheroid biologics (ETSB) using a dynamic EMT-3D-floating system along with 160 Gy X-ray-amelioration, which inoculates subcutaneously into aging rhesus and athymic Balb/c mice. Herein, it is bioinformatically validated that ETSB can reset Clock/Arntl-Per3/Tim molecule rhythm dynamics to re-prime thymus residual (parathyroid or fatty-like invalid vesicles yet no thymic architecture) to evolutionary transcription with overall cortex-medulla endogenized by TECs undergoing MET/EMT reversion.

Three-Dimensional Ameliorated Biologics Elicit Thymic Renewal in Tumor-Bearing Hosts.

Cancer-initiating/sustaining stem cell subsets (CSCs) have the potential to regenerate cancer cell populations and are resistant to routine therapeutic strategies, thus attracting much attention in anticancer research. In this study, an innovative framework of endogenous microenvironment-renewal for addressing such a dilemma has been just developed. CSCs in three-dimensional multipotent spheroid-engineered biologics were prepared with 150 Gy radiation and inoculated into 15-mo-old BALB/c and C57BL/6 mice bearing diverse advanced tumors covering Mammary 4T1, liver Hepa, lung LL/2, and colon C26 tumors and distant metastases.
