The loss of epithelial cell polarity plays an important role in the development and progression of liver cancer. However, the specific molecular mechanisms supporting tumor initiation and progression are poorly understood. In this study, transcriptome data and immunofluorescence stains of tissue samples derived from hepatocellular carcinoma (HCC) patients revealed that overexpression associated with cytoplasmic localization of the baso-lateral cell polarity complex protein Scribble (Scrib) correlated with poor prognosis of HCC patients...

Fibroblast differentiation is key cellular process that underlies the process of fibrosis, a deadly complication of fibrotic diseases like Scleroderma (SSc). This transition coincides with the overproduction of Collagen type I (COL1) and other extracellular matrix proteins. High level expression of the collagen type 1α2 subunit (COL1A2), requires the engagement of a far upstream enhancer, whose activation is strongly dependent on the AP1 factor JunB. We now report that STAT3 also binds the COL1A2 enhancer and is essential for RNA polymerase recruitment, without affecting JunB binding...

MicroRNAs are important components of the post-transcriptional fine-tuning of macrophage gene expression in physiological and pathological conditions. However, the mechanistic underpinnings and the cis-acting genomic factors of how macrophage polarizing signals induce miRNA expression changes are not well characterized. Therefore, we systematically evaluated the transcriptional basis underlying the inflammation-mediated regulation of macrophage microRNome using the combination of different next generation sequencing datasets...

Unraveling mechanisms underlying diseases has motivated the development of systems biology approaches. The key challenges for the development of mathematical models and computational tool are (1) the size of molecular networks, (2) the nonlinear nature of spatio-temporal interactions, and (3) feedback loops in the structure of interaction networks. We here propose an integrative workflow that combines structural analyses of networks, high-throughput data, and mechanistic modeling. As an illustration of the workflow, we use prostate cancer as a case study with the aim of identifying key functional components associated with primary to metastasis transitions...

Culturing of allogeneic or autologous cells in three-dimensional bioresorbable scaffolds is an important step in the engineering of constructs for regenerative medicine, as well as for experimental systems to study the mechanisms of cell differentiation and cell-to-cell interaction. Artificial substrates can modulate the phenotype and functional activity of immobilized cells. Investigating these changes is important for understanding the fundamental processes underlying cellular interactions in a 3D microenvironment and for improving tissue-engineered structures...

Primary effusion lymphoma (PEL) caused by Kaposi's sarcoma-associated herpesvirus (KSHV) is characterized by lymphomatous effusion in body cavities and poor prognosis. There is still no effective treatment for PEL. Fucoidan, a major sulfated polysaccharide isolated from brown seaweeds, has an attractive array of bioactivities such as cancer inhibition. However, the effects of fucoidan on PEL cells remain unclear. We investigated the anti-PEL effects of fucoidan obtained from Cladosiphon okamuranus Tokida cultivated in Okinawa...

Observations from cultured cells, animal models and patients raise the possibility that the dependency of tumours on the therapeutic drugs to which they have acquired resistance represents a vulnerability with potential applications in cancer treatment. However, for this drug addiction trait to become of clinical interest, we must first define the mechanism that underlies it. We performed an unbiased CRISPR-Cas9 knockout screen on melanoma cells that were both resistant and addicted to inhibition of the serine/threonine-protein kinase BRAF, in order to functionally mine their genome for 'addiction genes'...

Preterm labour (PTL) is a leading cause of perinatal mortality and postnatal morbidity. Contractions of the uterine muscle (myometrium) that determine the onset of labour depend on the expression of contraction-associated proteins (CAPs, i.e. connexin43) regulated by dimeric AP-1 transcription factors. Here, we examined subcellular (by immunoblotting) and tissue expression (by immunohistochemistry) of myometrial AP-1 proteins (cJUN, JUNB, JUND, cFOS, FOSB, FRA1, FRA2) throughout gestation and TL in different species (mouse, rat and human)...

MicroRNAs (miRs) serve important roles in cancer genesis and progression. The expression of miR-1908 has been reported in a number of types of cancer; however, the clinical significance of miR-1908 in human ovarian cancer (OC) remains unclear. A total of 491 patients with OC from The Cancer Genome Atlas project cohort were selected and divided into two groups according to the median expression level of miR-1908. Univariate and multivariate analyses, using the Kaplan-Meier method and Cox regression, were performed to identify the characteristics that predict OC prognosis...

BACKGROUND: Chondrogenic differentiation of mesenchymal stem cells (MSC) requires transforming growth factor beta (TGFβ) signaling. TGFβ binds to the type I receptor activin-like kinase (ALK)5 and results in C-terminal SMAD2/3 phosphorylation (pSMAD2/3C). In turn pSMAD2/3C translocates to the nucleus and regulates target gene expression. Inflammatory mediators are known to exert an inhibitory effect on MSC differentiation. In this study we investigated the effect of interleukin 1 β (IL1β) on SMAD2/3 signaling dynamics and post-translational modifications...

Melanoma resistant to MAPK inhibitor(s) (MAPKi) displays loss-of-fitness upon experimental MAPKi withdrawal and, clinically, may be re-sensitized to MAPKi therapy after a drug holiday. Here, we uncovered and therapeutically exploited the mechanisms of MAPKi-addiction in MAPKi-resistant MUTBRAF or MUTNRAS melanoma. MAPKi-addiction phenotypes evident upon drug-withdrawal spanned transient cell-cycle slow-down to cell-death responses, the latter of which required a robust p-ERK rebound. Generally, drug withdrawal-induced p-ERK rebound up-regulated p38-FRA1-JUNB-CDKN1A and down-regulated proliferation, but only a robust p-ERK rebound resulted in DNA damage and parthanatos-related cell death...

Previous studies demonstrated significant roles of autophagy in the pathogenesis of sepsis, but few studies focused on the effect of autophagy-related SNPs on sepsis susceptibility. In this present study, five polymorphisms of ATG5/ATG16L1 were investigated for the possible risk on sepsis in a Chinese Han population. Our results showed that ATG5 expression levels decreased with the severity of sepsis, and rs506027 T > C and rs510432 G > A were associated with sepsis progression and mortality. Moreover, the rs506027 TT and rs510432 GG carriers also exhibited increased expression levels of ATG5...

This study aimed to identify the key differentially expressed genes (DEGs) following ischemic stroke (IS).The GSE22255 microarray dataset, which contains samples from peripheral blood mononuclear cells of 20 IS patients and 20 sex- and age-matched controls, was downloaded from the Gene Expression Omnibus. After data pre-processing, DEGs were identified using the Linear Models for Microarray Data package in R. The Search Tool for the Retrieval of Interacting Genes database was used to predict the interactions among the products of DEGs, and then Cytoscape software was used to visualize the protein-protein interaction (PPI) network...

OBJECTIVES: Transdifferentiation is defined as the conversion of one cell type to another and is an ever-expanding field with a growing number of cells found to be capable of such a process. To date, the fact remains that there are limited treatment options for fracture healing, osteoporosis and bone repair post-destruction by bone tumours. Hence, this review focuses on the transdifferentiation of myoblast to osteoblast as a means to further understand the transdifferentiation process and to investigate a potential therapeutic option if successful...

Ginsenoside 20(S)-Rh2 has been shown to induce apoptosis and differentiation of acute myeloid leukemia (AML) cells. However, the underlying molecular mechanisms are not fully understood. In our study, 20(S)-Rh2 induced the expression of orphan nuclear receptor Nur77 and death receptor proteins Fas, FasL, DR5, and TRAIL, as well as the cleavage of caspase 8 and caspase 3 in HL-60 cells. Importantly, shNur77 attenuated 20(S)-Rh2-induced apoptosis and Fas and DR5 expression. Meanwhile, 20(S)-Rh2 promoted Nur77 translocation from the nucleus to mitochondria and enhanced the interaction between Nur77 and Bcl-2, resulting in the exposure of the BH3 domain of Bcl-2 and activation of Bax...

CO2 fluxes across water-air interfaces of river systems play important roles in regulating the regional and global carbon cycle. However, great uncertainty remains as to the contribution of these inland water bodies to the global carbon budget. Part of the uncertainty stems from limited understanding of the CO2 fluxes at diurnal and seasonal frequencies caused by aquatic metabolism. Here, we measured surface water characteristics (temperature, pH, and DO, DIC, Ca(2+) concentrations) and CO2 fluxes across the air-water interface at two transects of Guijiang River, southwest China to assess the seasonal and diurnal dynamics of fluvial carbon cycling and its potential role in regional and global carbon budgets...

Aldehyde dehydrogenase 1 (ALDH1A1)-positive dopaminergic (DA) neurons at the ventral substantia nigra pars compacta (SNpc) preferentially degenerate in Parkinson's disease (PD). Their projection pattern and dopamine release properties, however, remains uncharacterized. Here we show that ALDH1A1-positive axons project predominantly to the rostral two-thirds of dorsal striatum. A portion of these axons converge on a small fraction of striosome compartments restricted to the dorsolateral striatum (DLS), where less dopamine release was measured compared to the adjacent matrix enriched with the ALDH1A1-negative axons...

Classical Hodgkin lymphoma (cHL) and anaplastic large cell lymphoma (ALCL) feature high expression of activator protein-1 (AP-1) transcription factors, which regulate various physiological processes but also promote lymphomagenesis. The AP-1 factor basic leucine zipper transcription factor, ATF-like 3 (BATF3), is highly transcribed in cHL and ALCL; however, its functional importance in lymphomagenesis is unknown. Here we show that proto-typical CD30(+) lymphomas, namely cHL (21/30) and primary mediastinal B-cell lymphoma (8/9), but also CD30(+) diffuse large B-cell lymphoma (15/20) frequently express BATF3 protein...
