Increasing evidences suggested that radiotherapy can paradoxically promote tumor invasion and metastatic processes, while its detailed mechanism is not well illustrated. Our present study found that radiation can promote the migration and invasion of hepatocellular carcinoma (HCC) cells via induction of epithelial mesenchymal transition (EMT), which was evidenced by the results that radiation induced up regulation of vimentin while down regulation of E-Cadherin. As to the EMT-related transcription factors, radiation increased the expression of Snail, while not Slug, ZEB1 or TWIST...

Polysaccharide (EPS1-1) extracted from fermentation liquor of Rhizopus nigricans possesses antitumor and immune-enhancing activities. The study was the first to investigate the anti-metastasis effects of EPS1-1 in vitro and in vivo. Results suggested that EPS1-1 dose-dependently suppressed the migration, invasion and adhesion abilities of CT26 cells. Furthermore, EPS1-1 dramatically inhibited the enzyme activity and expression levels of matrix metalloproteinases (MMPs) in CT26 cells, as well as the tube formation of HUVECs...

Biophysical properties of the desired biomimetic scaffolds, such as porosity and elasticity, have been proven associated with the efficacy of cartilage regeneration. In this work, the copolymers of poly(L-alanine)-block-poly(ethylene glycol)-block-poly(L-alanine) (PA-PEG-PA) and poly(L-alanine-co-L-phenylalanine)-block-poly(ethylene glycol)-block-poly(L-alanine-co-L-phenylalanine) (PAF-PEG-PAF) with different ratios of alanine to phenylalanine were synthesized. The introduction of a hydrophobic amino acid, phenylalanine, into polyalanine-based thermosensitive hydrogel leaded to the enhanced gelation behaviors and upregulated mechanical properties...

The Japanese ornamental carp (Cyprinus carpio var. Koi) is famous for multifarious colors and patterns, making it commonly culture and trade across the world. Although functional genes and inheritance of color traits have been commonly studied, seldom attentions were focused on the genetic regulation during the developmental process of pigmentation. To better understand the mechanism of skin color development, we observed the morphogenesis of pigment cells during the post-embryonic stages and analysed the temporal expression pattern of mRNAs/miRNAs profiles in four distinct developmental stages...

The main problem in the treatment of non-small cell lung cancer (NSCLC) is metastasis. Epithelial-mesenchymal transition (EMT) is known as the critical signaling in tumor progression, metastasis, and also the drug resistance. In this study, we reported a novel gene Polymerase delta-interacting protein 2 (POLDIP2) was downregulated in NSCLC tissues and first demonstrated that overexpression of POLDIP2 increased the anchorage-independent growth (AIG) and invasiveness of H1299 cells. In addition, we examined that knockdown of POLDIP2 in H1299 and A549 cells reduced tumorigenicity and metastatic capacity in vitro and also in vivo...

During development, the embryo transitions from a metabolism favoring glycolysis to a metabolism favoring mitochondrial respiration. How metabolic shifts regulate developmental processes, or how developmental processes regulate metabolic shifts, remains unclear. To test the requirement of mitochondrial function in developing endoderm-derived tissues, we genetically inactivated the mitochondrial transcription factor, Tfam, using the Shh-Cre driver. Tfam mutants did not survive postnatally, exhibiting defects in lung development...

Zinc is an essential micronutrient required for proper structure and function of many proteins. Bacteria regularly encounter zinc depletion and have evolved diverse mechanisms to continue growth when zinc is limited, including the expression of zinc-independent paralogs of zinc-binding proteins. Mycobacteria have a conserved operon encoding four zinc-independent alternative ribosomal proteins (AltRPs) that are expressed when zinc is depleted. It is unknown if mycobacterial AltRPs replace their primary paralogs in the ribosome and maintain protein synthesis under zinc-limited conditions, and if such replacements contribute to their physiology...

Esophageal squamous cell carcinoma (ESCC) is an aggressive upper gastrointestinal cancer and effective treatments are limited. Previous studies reported that natural killer (NK) cells expanded by coculturing with K562-mb15-41BBL feeder cells, a genetically modified K562 leukemia cell line that expresses membrane-bound interleukin (IL)-15 and 41BBL ligand, were highly proliferative and highly cytotoxic. Here, we investigated the potential of expanded NK cells for ESCC treatment. We analyzed both genetic and surface expression levels of NKG2D ligands (NKG2DLs) in ESCC using publicly available microarray data sets and ESCC cell lines...

Sirtuin 3 (Sirt3) has a promising role in cancer tumourigenesis and treatment, but there have been controversies about its role as oncogene or tumour suppressor in different types of cancer. Changes in its expression are associated with the excessive production of reactive oxygen species (ROS), thus contributing to mitochondrial dysfunction and age-related pathologies. Hyperoxic treatment (i.e. generator of ROS) was shown to support some tumourigenic properties, but finally suppresses growth of certain mammary carcinoma cells...

Many studies have shown that microRNAs (miRNAs) play important roles in the development of idiopathic pulmonary fibrosis (IPF). The purpose of this review is to systematically summarize the recent advance of miRNAs in the pathology of IPF, highlighting the new research progress and their pathophysiological implication. Recent studies have shown that miRNAs differentially expressed in blood and lung tissue from IPF patients are closely related to the occurrence of IPF disease, which may be IPF diagnostic markers and prognostic indicators...

Idiopathic pulmonary fibrosis (IPF) is a chronic, progressive, fibrotic parenchymal lung disease of unknown etiology and lacks an effective intervention. Long noncoding RNAs (lncRNAs) participate in organ fibrosis and various pulmonary diseases, but the role of lncRNAs in lung fibrosis is not fully understood. In the present study, we identified that lncRNA NONMMUT021928, designated as pulmonary fibrosis-associated lncRNA (PFAL), was up-regulated in the lungs of mice with experimental lung fibrosis, and in TGF-β1-induced fibrotic lung fibroblasts...

One of the most important chemical reactions for renewable energy technologies such as fuel cells and metal-air batteries today is oxygen reduction. Due to the relatively sluggish reaction kinetics, catalysts are necessary to generate high power output. The most common catalyst for this reaction is platinum, but its scarcity and derived high price have raised the search for abundant nonprecious metal catalysts. Inspired from enzymatic processes which are known to catalyze oxygen reduction reaction efficiently, employing transition metal complexes as their catalytic centers, many are working on the development of bioinspired and biomimetic catalysts of this class...

Cyclin-dependent kinases are Ser/Thr protein kinases best known for their cell cycle roles, where CDK1 triggers mitotic onset in all eukaryotes. CDKs are also involved in various other cellular processes, some of which, such as transcription and centrosome duplication, are coupled to cell cycle progression. A new study suggests that the mitotic CDK network is active at low levels in non-dividing, differentiating precursors of multiciliated cells, and that it drives ciliogenesis. Manipulating the activity of CDK1 or PLK1 altered transitions between the amplification, growth, and disengagement phases, in a manner analogous to the control of passage through different phases of mitosis...

Acetaminophen (APAP) overdose is the most frequent cause of liver injury and acute liver failure in many western countries. The mechanism of APAP-induced hepatocyte necrosis has been investigated extensively. The formation of a reactive metabolite and its binding to cellular proteins was initially thought to be responsible for cell death. A competing hypothesis was introduced that questioned the relevance of protein binding and instead suggested that P450-derived oxidant stress and lipid peroxidation causes APAP-induced liver injury...

The immune response to biomaterial implants critically regulates functional outcomes such as vascularization, transplant integration/survival, and fibrosis. To create "immunologically smart" materials, the host-material response may be engineered to optimize the recruitment of pro-regenerative leukocyte subsets which mature into corresponding wound-healing macrophages. We have recently identified a unique feature of pro-regenerative Ly6Clow monocytes that is a higher expression of both the bioactive lipid receptor sphingosine-1-phosphate receptor 3 (S1PR3) and the stromal derived factor-1α (SDF-1α) receptor CXCR4...

The glycolytic enzyme Hexokinase (HKII) participates in tumor glycolysis and the progression of various cancers, but its clinicopathological effect on the progression of tongue squamous cell carcinoma (TSCC) and its role in glycolysis, autophagy, and the epithelial-mesenchymal transition of TSCC in a hypoxic microenvironment remain unknown. Our results showed that HKII expression was dramatically increased in TSCC tissues and that its upregulation was significantly associated with the presence of pathological differentiation, lymph node metastasis, and clinical stage...

Background: Non-small cell lung cancer (NSCLC) is the most common cause of cancer-related mortality; nevertheless, there are few data regarding detection of circulating tumor cells (CTCs) in NSCLC, compared to other kinds of cancers in which their prognostic roles have already been defined. This difference is likely due to detection methods based on the epithelial marker expression which ignore CTCs undergoing epithelial-mesenchymal transition (CTCsEMT ). Methods: After optimization of the test with spiking experiments of A549 cells undergoing TGF- β 1-induced EMT (A549EMT ), the CTCsEMT were enriched by immunomagnetic depletion of leukocytes and then characterized by a RT-PCR assay based on the retrieval of epithelial and EMT-related genes...

Cyclin-dependent kinases (CDKs) are pivotal kinases in cell cycle transition and gene transcription. A series of N 2 , N 4 -diphenylpyrimidine-2,4-diamines were previously identified as potent CDK2/CDK9 inhibitors. To explore the SAR of this structural prototype, twenty-four novel N 2 , N 4 -disubstituted pyrimidine-2,4-diamines were designed and synthesized. Among them, twenty-one compounds exhibited potent inhibitory activities against both CDK2/cyclin A and CDK9/cyclin T1 systems, and the most potent CDK2 and CDK9 inhibitors, 3g and 3c , showed IC50 values of 83 nM and 65 nM respectively...

Controlling lung cancer cell migration and invasion via epithelial-to-mesenchymal transition (EMT) through the regulation of epidermal growth factor receptor (EGFR) signaling pathway has been demonstrated. Searching biological active phytochemicals to repress EGFR-regulated EMT might prevent lung cancer progression. Propolis has been used as folk medicine in many countries and possesses anti-inflammatory, antioxidant, and anticancer activities. In this study, the antimigration and anti-invasion activities of propolin C, a c-prenylflavanone from Taiwanese propolis, were investigated on EGFR-regulated EMT signaling pathway...

Background: Metastatic dissemination of solid tumors is often initiated by reactivation of an embryonic development program, epithelial-to-mesenchymal-transition (EMT). EMT has been associated with acquiring invasiveness and resistance to conventional therapies. However, the precise role of EMT during renal cell carcinoma is still debatable and is under investigation. In this context, our study is designed to evaluate the role of cyclosporine (CsA) and transforming growth factor-β (TGFβ) administration in inducing EMT-like state in renal carcinoma cells...
