Metabolic signaling directs the reciprocal lineage decisions of αβ and γδ T cells.

The interaction between extrinsic factors and intrinsic signal strength governs thymocyte development, but the mechanisms linking them remain elusive. We report that mechanistic target of rapamycin complex 1 (mTORC1) couples microenvironmental cues with metabolic programs to orchestrate the reciprocal development of two fundamentally distinct T cell lineages, the αβ and γδ T cells. Developing thymocytes dynamically engage metabolic programs including glycolysis and oxidative phosphorylation, as well as ...


Lean on Me: Cell-Cell Interactions Release TGF-β for Local Consumption Only.

A new study combines detailed biochemical characterization with whole-animal genetics and computational transcriptome data mining to reveal how the LRRC33 milieu molecule imposes an exquisite level of spatial control on TGF-β signaling in the CNS.

B cell development is critically dependent on NFATc1 activity.

B cell development in bone marrow is a precisely regulated complex process. Through successive stages of differentiation, which are regulated by a multitude of signaling pathways and an array of lineage-specific transcription factors, the common lymphoid progenitors ultimately give rise to mature B cells. Similar to early thymocyte development in the thymus, early B cell development in bone marrow is critically dependent on IL-7 signaling. During this IL-7-dependent stage of differentiation, several transcr...


TGF-β signaling in cancer.

Signals from the transforming growth factor-β (TGF-β) superfamily mediate a broad spectrum of cellular processes and are deregulated in many diseases, including cancer. TGF-β signaling has dual roles in tumorigenesis. In the early phase of tumorigenesis, TGF-β has tumor suppressive functions, primarily through cell cycle arrest and apoptosis. However, in the late stage of cancer, TGF-β acts as a driver of tumor progression and metastasis by increasing tumor cell invasiveness and migration and promoting...

Revealing the Critical Regulators of Cell Identity in the Mouse Cell Atlas.

Recent progress in single-cell technologies has enabled the identification of all major cell types in mouse. However, for most cell types, the regulatory mechanism underlying their identity remains poorly understood. By computational analysis of the recently published mouse cell atlas data, we have identified 202 regulons whose activities are highly variable across different cell types, and more importantly, predicted a small set of essential regulators for each major cell type in mouse. Systematic validati...

Class II MHC cytoplasmic domain-mediated signaling in B cells: A tail of two signals.

In addition to their role in antigen presentation, class II MHC molecules also transmit signals to B lymphocytes. Class II MHC-mediated signals initiate a range of events in B cells, including induction of cell surface proteins, initiation of cell-cycle progression/proliferation, activation of or protection from apoptosis, and antigen-dependent plasma cell differentiation. Although various transmembrane signaling proteins associate with class II MHC molecules, the class II MHC cytoplasmic domains are essent...

Stem Cell Therapies for Neurodegenerative Diseases.

Stem cell therapies have been proposed as a treatment option for neurodegenerative diseases, but the best stem cell source and therapeutic efficacy for neuroregeneration remain uncertain. Embryonic stem cells (ESCs) and neural stem cells (NSCs), which can efficiently generate neural cells, could be good candidates but they pose ethical and practical issues. Not only difficult to find the good source of those cells but also they alway pose immunorejection problem since they may not be an autologous cells. Ev...

ROS Promotes Cancer Cell Survival through Calcium Signaling.

To avoid reactive oxygen species (ROS)-induced cell death, cancer cells increase their antioxidant defense system. In this issue of Cancer Cell, Takahashi et al. identify a novel, non-canonical oxidative stress defense mechanism involving TRPA1, a redox-sensitive Ca channel, and the upregulation of anti-apoptotic pathways to promote cancer cell survival.

A novel inhibitor targets both Wnt signaling and ATM/p53 in colorectal cancer.

For 2017, the estimated lifetime risk of developing colorectal cancer (CRC) was 1 in 22. Even though preventative colonoscopy screening and standard of care surgery, radiation, and chemotherapy have decreased the death rate from CRC, new therapies are needed for metastatic CRC. Here we developed a novel small molecule, compound 2, that inhibited proliferation and viability of human CRC cells (HCT-116, DLD-1, SW480, and 10.1). Compound 2 inhibited cell migration, invasion, and EMT processes and potently incr...

Cytoplasmic Intermediate Filaments in Cell Biology.

Intermediate filaments (IFs) are one of the three major elements of the cytoskeleton. Their stability, intrinsic mechanical properties, and cell type-specific expression patterns distinguish them from actin and microtubules. By providing mechanical support, IFs protect cells from external forces and participate in cell adhesion and tissue integrity. IFs form an extensive and elaborate network that connects the cell cortex to intracellular organelles. They act as a molecular scaffold that controls intracellu...

Molecular advances in cutaneous T-cell lymphoma.

Cutaneous T-cell lymphoma (CTCL) is a group of malignancies derived from skin-homing T cells. Mycosis fungoides (MF) and Sézary syndrome (SS) are the most common CTCL variants. In recent years, the genetic landscape of SS/MF has been characterized using genome-wide nextgeneration sequencing approaches. These studies have revealed that genes subjected to oncogenic mutations take part in cell cycle regulation, chromatin modification, Janus kinase (JAK)-signal transducer and activator of transcription protein...

Complementary Wnt Sources Regulate Lymphatic Vascular Development via PROX1-Dependent Wnt/β-Catenin Signaling.

Wnt/β-catenin signaling is necessary for lymphatic vascular development. Oscillatory shear stress (OSS) enhances Wnt/β-catenin signaling in cultured lymphatic endothelial cells (LECs) to induce expression of the lymphedema-associated transcription factors GATA2 and FOXC2. However, the mechanisms by which OSS regulates Wnt/β-catenin signaling and GATA2 and FOXC2 expression are unknown. We show that OSS activates autocrine Wnt/β-catenin signaling in LECs in vitro. Tissue-specific deletion of Wntless, whi...

Dihydroartemisinin induces apoptosis and inhibits proliferation, migration, and invasion in epithelial ovarian cancer via inhibition of the hedgehog signaling pathway.

Dihydroartemisinin (DHA), the primary of artemisinin extracted from the traditional Chinese medicine Artemisia annua, has been used in malaria treatment for a long time. Recently, many studies have indicated that, in addition to antimalarial effects, DHA also exhibits anticancer activity in certain types of neoplasms, including ovarian cancer. However, the precise anti-ovarian cancer mechanism of DHA is still unclear. Abnormal activation of the hedgehog (Hh) pathway is closely related to tumorigenesis and p...

Myeloid p38α signaling promotes intestinal IGF-1 production and inflammation-associated tumorigenesis.

The protein kinase p38α plays a key role in cell homeostasis, and p38α signaling in intestinal epithelial cells protects against colitis-induced tumorigenesis. However, little is known on the contribution of p38α signaling in intestinal stromal cells. Here, we show that myeloid cell-specific downregulation of p38α protects mice against inflammation-associated colon tumorigenesis. The reduced tumorigenesis correlates with impaired detection in the colon of crucial chemokines for immune cell recruitment. ...

Harnessing CXCL12 signaling to protect and preserve functional β-cell mass and for cell replacement in type 1 diabetes.

Type 1 diabetes (T1D) is a complex multifactorial disease characterized by autoimmune destruction of insulin-producing pancreatic β cells. Our understanding of the pathogenic mechanisms and natural history of T1D has evolved significantly over the past two decades; we can efficiently predict high-risk individuals, early diagnose the disease and stage progression. Fortuitously, novel in vitro differentiation protocols for generating functional β-like cells from human pluripotent stem cells have been develo...

GTPases Rac1 and Ras Signaling from Endosomes.

The endocytic compartment is not only the functional continuity of the plasma membrane but consists of a diverse collection of intracellular heterogeneous complex structures that transport, amplify, sustain, and/or sort signaling molecules. Over the years, it has become evident that early, late, and recycling endosomes represent an interconnected vesicular-tubular network able to form signaling platforms that dynamically and efficiently translate extracellular signals into biological outcome. Cell activatio...

Centromeric signaling proteins boost G1 cyclin degradation and modulate cell size in budding yeast.

Cell size scales with ploidy in a great range of eukaryotes, but the underlying mechanisms remain unknown. Using various orthogonal single-cell approaches, we show that cell size increases linearly with centromere (CEN) copy number in budding yeast. This effect is due to a G1 delay mediated by increased degradation of Cln3, the most upstream G1 cyclin acting at Start, and specific centromeric signaling proteins, namely Mad3 and Bub3. Mad3 binds both Cln3 and Cdc4, the adaptor component of the Skp1/Cul1/F-bo...

Perfluorooctanoic acid stimulates ovarian cancer cell migration, invasion via ERK/NF-κB/MMP-2/-9 pathway.

As widely used in consumer products, perfluorooctanoic acid (PFOA) has become a common environmental pollutant, which has been detected in human serum and associated with cancers. Our previous study showed that PFOA is a carcinogen that promotes endometrial cancer cell migration and invasion through activation of ERK/mTOR signaling. Here, we showed that PFOA (≥100 nM) treatment also stimulated A2780 ovarian cancer cell invasion and migration, which correlated with increased matrix metalloproteinases MMP...

Interleukin-6 secretion is limited by self-signaling in endosomes.

Cells producing cytokines often express the receptor for the same cytokine, which makes them prone to autocrine signaling. How cytokine release and signaling are regulated in the same cell is not understood. In this study, we demonstrate that signaling by exogenous and self-synthesized inflammatory cytokine interleukin-6 (IL-6) within endosomal compartments acts as a cellular brake that limits synthesis of IL-6. Our data show that IL-6 is internalized by dendritic cells and signals from endosomal compartmen...

Erbin suppresses KSR1-mediated RAS/RAF signaling and tumorigenesis in colorectal cancer.

Erbin belongs to the LAP (leucine-rich repeat and PDZ domain) family of scaffolding proteins that plays important roles in orchestrating cell signaling. Here we show that Erbin functions as a tumor suppressor in colorectal cancer (CRC). Analysis of Erbin expression in CRC patient specimens revealed that Erbin was downregulated at both mRNA and protein levels in tumor tissues. Knockdown of Erbin disrupted epithelial cell polarity and increased cell proliferation in 3D culture. In addition, silencing Erbin re...

Ric-8A, a GEF for heterotrimeric G-proteins, controls cranial neural crest cell polarity during migration.

The neural crest (NC) is a transient embryonic cell population that migrates extensively during development. Ric-8A, a guanine nucleotide exchange factor (GEF) for different Gα subunits regulates cranial NC (CNC) cell migration in Xenopus through a mechanism that still remains to be elucidated. To properly migrate, CNC cells establish an axis of polarization and undergo morphological changes to generate protrusions at the leading edge and retraction of the cell rear. Here, we aim to study the role of Ric-8...

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...

Emerging role and therapeutic implication of Wnt signaling pathways in liver fibrosis.

Activation of hepatic stellate cells (HSCs) is a pivotal cellular event in liver fibrosis. Therefore, improving our understanding of the molecular pathways that are involved in these processes is essential to generate new therapies for liver fibrosis. Greater knowledge of the role of the Wnt signaling pathway in liver fibrosis could improve understanding of the liver fibrosis pathogenesis. The aim of this review is to describe the present knowledge about the Wnt signaling pathway, which significantly partic...

Differential Regulation of Cell Proliferation and Apoptosis by Melatonin Receptor Subtype-Signaling in the Adult Murine Brain.

Background/Aims: Zeitgeber time (ZT)-dependent changes in cell proliferation and apoptosis are regulated by melatonin receptor (MT)-mediated signaling in the adult hippocampus and hypothalamic-hypophyseal system. There are two G-protein-coupled MT-subtypes, MT1 and MT2. Therefore, the present study examined which MT-subtype is required for regulation of ZT-dependent changes in cell proliferation and/or apoptosis in the adult murine brain and pituitary.
