LINC00707 promotes hepatocellular carcinoma progression through activating ERK/JNK/AKT pathway signaling pathway.

Increasing evidence has demonstrated that abnormal expression of lncRNA is correlated with various malignant tumors, including hepatocellular carcinoma (HCC). Our current study was aimed to investigate the role of LINC00707 in HCC development. We observed that LINC00707 was upregulated in HCC cell lines compared with normal liver cell lines. Then, Hep3B cells and SNU449 cells were infected with LV-shLINC00707 and LV-LINC00707. LINC00707 silencing could greatly repress the proliferation and colony formation ...


Really interesting new gene finger protein 121 is a tumor suppressor of renal cell carcinoma.

Really interesting new gene finger protein (RING) finger protein 121 (RNF-121) is an E3 ubiquitin ligase involved in the regulation of several signaling pathways. Among those signaling pathways, nuclear factor-κB (NF-κB) signaling pathway is known to play a critical role in tumorigenesis. However, the relevance between RNF121 and cancer development remains poorly understood. In this study, we found that RNF121 was less expressed in tumor tissues than adjacent normal tissues of renal cell carcinoma (RCC) p...

Genetic Engineering of Dictyostelium discoideum Cells Based on Selection and Growth on Bacteria.

Dictyostelium discoideum is an intriguing model organism for the study of cell differentiation processes during development, cell signaling, and other important cellular biology questions. The technologies available to genetically manipulate Dictyostelium cells are well-developed. Transfections can be performed using different selectable markers and marker re-cycling, including homologous recombination and insertional mutagenesis. This is supported by a well-annotated genome. However, these approaches are o...


TLR9 Signaling Suppresses the Canonical Plasma Cell Differentiation Program in Follicular B Cells.

The relative potency and quality of mouse B cell response to Toll-like receptors (TLRs) signaling varies significantly depending on the B cell subset and on the TLR member being engaged. Although it has been shown that marginal zone cells respond faster than follicular (FO) splenic B cells to TLR4 stimulus, FO B cells retain full capacity to proliferate and generate plasmablasts and plasma cells (PBs/PCs) with 2-3 days delayed kinetics. It is not clear whether this scenario could be extended to other member...

BMP signaling is required for nkx2.3-positive pharyngeal pouch progenitor specification in zebrafish.

Pharyngeal pouches, a series of outpocketings that bud from the foregut endoderm, are essential to the formation of craniofacial skeleton as well as several important structures like parathyroid and thymus. However, whether pharyngeal pouch progenitors exist in the developing gut tube remains unknown. Here, taking advantage of cell lineage tracing and transgenic ablation technologies, we identified a population of nkx2.3+ pouch progenitors in zebrafish embryos and demonstrated an essential requirement of ec...

Synergistic interaction of Deltex and Hrp48 leads to JNK activation.

The communication among the cells plays a seminal role in metazoan development by coordinating multiple cellular processes that, in turn, helps in the maintenance of biological homeostasis. Our previous study demonstrated that Dx and Hrp48 together downregulate Notch signaling and induce cell death in Drosophila. To understand the signaling events behind the Dx and Hrp48-induced cell death in a greater detail, we performed a set of genetic experiments followed by immunocytochemical analyses. Our data reveal...

Sevoflurane affects neurogenesis through cell cycle arrest via inhibiting wnt/β-catenin signaling pathway in mouse neural stem cells.

The development of central nervous system requires proliferation of neural stem cells followed by differentiation. Cell cycle parameters are closely related with cell fate specification and differentiation. Recent researches indicated that wnt/β-catenin signaling pathway might cause proliferation inhibition and differentiation abnormality through interfering NSCs cell cycle. Our previous research also showed that multiple sevoflurane exposure to neural stem cells inhibited proliferation via repressing tran...

Lysosomes Dare Cells to be Different(iated).

In this issue of Cell Stem Cell, Villegas et al. (2019) used a genome-wide CRISPR screen to identify ESC pluripotency regulators, which generated insights into how signaling from lysosome enables cells to transcriptionally regulate their metabolism. Further investigation of human genetics identified a human developmental disease arising from a defect in this process.

Proteomic analysis of human T cell-derived exosomes reveals differential RAS/MAPK signaling.

Exosomes are cell derived vesicles that have been implicated in the pathogenesis of many inflammatory diseases. More specifically, it has been shown that T cell-derived exosomes can induce immunological responses; however, little is known about the mechanism and the molecular content of these vesicles. Here, we used a proteomic approach to characterize human T cell-derived exosomes. We found that specific proteins of the RAS signaling pathway were enriched in exosomes derived from activated T cells, and tha...

Hepatic stellate cells regulate hepatic progenitor cells differentiation via the TGF-β1/Jagged1 signaling axis.

Hepatic stellate cells (HSCs) play an important microenvironmental role in hepatic progenitor cells (HPCs) differentiation fate. To reveal the specific mechanism of HSCs induced by transforming growth factor β1 (TGF-β1) signaling in HPCs differentiation process, we used Knockin and knockdown technologies induced by lentivirus to upregulate or downregulate TGF-β1 level in mouse HSCs (mHSCs) (mHSCs-TGF-β1 or mHSCs-TGF-βR1sih3). Primary mouse HPCs (mHPCs) were isolated and were cocultured with mHSCs-TGF-...

Control of Blood Vessel Formation by Notch Signaling.

Blood vessels span throughout the body to nourish tissue cells and to provide gateways for immune surveillance. Endothelial cells that line capillaries have the remarkable capacity to be quiescent for years but to switch rapidly into the activated state once new blood vessels need to be formed. In addition, endothelial cells generate niches for progenitor and tumor cells and provide organ-specific paracrine (angiocrine) factors that control organ development and regeneration, maintenance of homeostasis and ...

Modeling the Notch Response.

NOTCH signaling regulates developmental processes in all tissues and all organisms across the animal kingdom. It is often involved in coordinating the differentiation of neighboring cells into different cell types. As our knowledge on the structural, molecular and cellular properties of the NOTCH pathway expands, there is a greater need for quantitative methodologies to get a better understanding of the processes controlled by NOTCH signaling. In recent years, theoretical and computational approaches to NOT...

Rapamycin rescues BMP mediated midline craniosynostosis phenotype through reduction of mTOR signaling in a mouse model.

Craniosynostosis is defined as congenital premature fusion of one or more cranial sutures. While the genetic basis for about 30% of cases is known, the causative genes for the diverse presentations of the remainder of cases are unknown. The recently discovered cranial suture stem cell population affords an opportunity to identify early signaling pathways that contribute to craniosynostosis. We previously demonstrated that enhanced BMP signaling in neural crest cells (caA3 mutants) leads to premature cranial...

TLK2 enhances aggressive phenotypes of glioblastoma cells through the activation of SRC signaling pathway.

Glioblastoma are among the most common forms of cancer affecting the central nervous system, and yet there is currently no effective means of treating them. In the current study, we reported that tousled-like kinase 2 (TLK2) is a key factor in glioblastoma that modulates SRC signaling, thereby driving tumor malignancy. TLK2 is commonly upregulated in glioblastoma, and such upregulation was associated with poor patient outcomes. TLK2 overexpression induced cell growth, migration, invasion, and epithelial-mes...

CD28-ζ CAR T Cells Resist TGF-β Repression through IL-2 Signaling, Which Can Be Mimicked by an Engineered IL-7 Autocrine Loop.

Adoptive cell therapy with chimeric antigen receptor (CAR)-redirected T cells induced spectacular regressions of leukemia and lymphoma, however, failed so far in the treatment of solid tumors. A cause is thought to be T cell repression through TGF-β, which is massively accumulating in the tumor tissue. Here, we show that T cells with a CD28-ζ CAR, but not with a 4-1BB-ζ CAR, resist TGF-β-mediated repression. Mechanistically, LCK activation and consequently IL-2 release and autocrine IL-2 receptor sig...

Sulforaphane inhibits growth and blocks Wnt/β-catenin signaling of colorectal cancer cells.

The naturally occurring isothiocyanate sulforaphane (SFN) from cruciferous vegetables is associated with growth inhibition of various cancer types, including colorectal cancer. Colorectal cancer is most frequently driven by hyperactive Wnt/β-catenin signaling. Here, we show that SFN treatment reduced growth of three unrelated colorectal cancer cell lines (SW480, DLD1 and HCT116) via induction of cell death and inhibition of proliferation. Importantly, SFN inhibits Wnt/β-catenin signaling in colorectal can...

JAG2 signaling induces differentiation of CD14 monocytes into Langerhans cell histiocytosis-like cells.

Langerhans cell histiocytosis (LCH) is a MAPK pathway-driven disease characterized by the accumulation of CD1a langerin cells of unknown origin. We have previously reported that the Notch signaling pathway is active in LCH lesions and that the Notch ligand Jagged2 (JAG2) induces CD1a and langerin expression in monocytes in vitro. Here we show that Notch signaling induces monocytes to acquire an LCH gene signature and that Notch inhibition suppresses the LCH phenotype. In contrast, while also CD1c dendritic ...

Histone Demethylase JMJD2D Interacts with Beta-catenin to Induce Transcription and Activate Colorectal Cancer Cell Proliferation and Tumor Growth in Mice.

Wnt signaling contributes to development of colorectal cancer (CRC). We studied interactions between lysine demethylase 4D (KDM4D or JMJD2D) and beta-catenin, a mediator of Wnt signaling, in CRC cell lines and the effects on tumor formation in mice.

Exposure of beta-cells to chronic fructose potentiates glucose-stimulated insulin secretion through ATP signaling.

While the use of fructose as a sweetener and its consumption are associated with increased fat storage prompted by the action of insulin, fructose alone does not acutely stimulate insulin exocytosis from the pancreatic beta-cell, as opposed to the chief secretagogue glucose. We investigated the effects of chronic exposure to fructose on beta-cell function. Our results reveal that chronic fructose induces extracellular ATP signaling in the beta-cell, resulting in the potentiation of glucose-stimulated insuli...

Adoption of Stroke Rehabilitation Technologies by the User Community: Qualitative Study.

Using technology in stroke rehabilitation is attractive. Devices such as robots or smartphones can help deliver evidence-based levels of practice intensity and automated feedback without additional labor costs. Currently, however, few technologies have been adopted into everyday rehabilitation.

Crosstalk between Dpp and Tor signaling coordinates autophagy-dependent midgut degradation.

The majority of developmentally programmed cell death (PCD) is mediated by caspase-dependent apoptosis; however, additional modalities, including autophagy-dependent cell death, have important spatiotemporally restricted functions. Autophagy involves the engulfment of cytoplasmic components in a double membrane vesicle for delivery to the lysosome. An established model for autophagy-dependent PCD is Drosophila larval midgut removal during metamorphosis. Our previous work demonstrated that growth arrest is r...

Peeking under the Hood of Naive T Cells.

Signaling and transcriptional regulation of metabolic reprogramming upon T cell activation has been studied intensively. In this issue of Cell Metabolism, Ricciardi et al. (2018) show that translational regulation of key metabolic enzymes GLUT1 and ACC1 plays a novel role in human naive CD4 T cell activation and subset differentiation.

Bonds Voyage! A Dissociative Model of TCR-CD3 Triggering Is Proposed.

How the T cell receptor (TCR)-CD3 complex activates T cells is debated. In this issue of Immunity, Brazin et al. (2018) propose that TCR engagement under force releases the CD3 signaling modules to disperse and adopt signaling active states.

Deformable 96-well cell culture plate compatible with high-throughput screening platforms.

Adherent cells such as endothelial cells sense applied mechanical stretch to adapt to changes in their surrounding mechanical environment. Despite numerous studies, signaling pathways underlying the cellular mechanosensing and adaptation remain to be fully elucidated partly because of the lack of tools that allow for a comprehensive screening approach. Conventionally, multi-well cell culture plates of standard configurations are used for comprehensive analyses in cell biology study to identify key molecules...

Tissue Factor at the crossroad of coagulation and cell signaling.

The tissue factor (TF) pathway plays a central role in hemostasis and thrombo-inflammatory diseases. Although structure-function relationships of the TF initiation complex are elucidated, new facets of the dynamic regulation of TF's activities on cells continue to emerge. Cellular pathways that render TF non-coagulant participate in signaling of distinct TF complexes with associated proteases through the protease-activated receptor (PAR) family of G-protein coupled receptors. Additional co-receptors, includ...
