AbstractThe ubiquitin-proteasome system and macroautophagy are two complementary pathways for protein degradation. Emerging evidence suggests that proteasome inhibition might be a promising approach for the treatment of cancer. In this study, we show that proteasome inhibitor MG-132 suppressed gastric cancer cell proliferation and induced macroautophagy. The induction of macroautophagy was evidenced by the formation of LC3(+) autophagosomes and the accumulation of acidic vesicular organelles and autolysosomes and was accompanied by the suppression of mammalian target of rapamycin complex 1 activity. Abolition of macroautophagy by knockdown of Class III phosphatidylinositol-3 kinase Vps34 or ATG5/7 sensitized gastric cancer cells to the antiproliferative effect of MG-132 by promoting G(2)/M cell cycle arrest. In addition, MG-132 increased ERK phosphorylation whose inhibition by MEK inhibitor significantly enhanced the antiproliferative effect of proteasome inhibition. To conclude, this study ...
Class I PI3Ks can form an allosteric or specificity pocket (adjacent to the adenine pocket) only in the presence of propeller-like inhibitors (29). The half-maximal inhibitory concentrations (IC50s) for the propeller-like PI3K inhibitors (e.g., PIK-39) (fig. S9) are generally much worse for Vps34 than other PI3Ks. This is probably due to increased rigidity of the Vps34 pocket arising from a bulky residue substituted in the P loop (Phe612-Hs, Phe673-Dm) that packs against the aromatic hinge residue unique to Vps34 (Phe684-Hs, Tyr746-Dm). These differences effectively close off a corner of the adenine-binding pocket, giving it a more constrained appearance.. Currently there is no high-affinity, specific inhibitor of Vps34. We determined the structure of a complex of Vps34 with 3-methyladenine (3-MA) (Fig. 4, B and C), which is often used as a specific inhibitor of autophagy. We also determined the structures of Vps34 in complexes with three multi-targeted inhibitors: (i) PIK-90, (ii) PIK-93, ...

Apoptotic cells generated by programmed cell death are engulfed by phagocytes and enclosed within membrane-bound phagosomes. Maturation of apoptotic cell-containing phagosomes leads to formation of phagolysosomes where cell corpses are degraded. The class III phosphatidylinositol 3-kinase (PI3-kinase) VPS-34 coordinates with PIKI-1, a class II PI3-kinase, to produce PtdIns3P on phagosomes, thus promoting phagosome closure and maturation. Here, we identified UBC-13, an E2 ubiquitin-conjugating enzyme that functions in the same pathway with VPS-34 but in parallel to PIKI-1 to regulate PtdIns3P generation on phagosomes. Loss of ubc-13 affects early steps of phagosome maturation, causing accumulation of cell corpses. We found that UBC-13 functions with UEV-1, a noncatalytic E2 variant, and CHN-1, a U-box-containing E3 ubiquitin ligase, to catalyze K63-linked poly-ubiquitination on VPS-34 both in vitro and in Caenorhabditis elegans. Loss of ubc-13, uev-1, or chn-1 disrupts ubiquitin modification of ...

Autophagy plays an important role in the regulation of autoimmune and autoinflammatory responses of the immune cells. Defective autophagy process is associated with various autoimmune and inflammatory diseases. Moreover, in many of these diseases, the therapeutic use of normal immunoglobulin G or intravenous immunoglobulin (IVIG), a pooled normal IgG preparation, is well documented. Therefore, we explored if IVIG immunotherapy exerts therapeutic benefits via induction of autophagy in the immune cells. Here we show that IVIG induces autophagy in peripheral blood mononuclear cells (PBMCs). Further dissection of this process revealed that IVIG-induced autophagy is restricted to inflammatory cells like monocytes, dendritic cells, and M1 macrophages but not in cells associated with Th2 immune response like M2 macrophages. IVIG induces autophagy by activating AMP-dependent protein kinase, beclin-1, class III phosphoinositide 3-kinase and p38 mitogen-activated protein kinase and by inhibiting mammalian target
Beclin 1/Atg6 is an essential component of the evolutionary conserved PtdIns(3)-kinase (Vps34) protein complex that regulates macroautophagy (autophagy) in eukaryotic cells and also interacts with antiapoptotic Bcl-2 family members, Bcl-2, and Bcl-x(L). To elucidate the physiological function of Beclin 1, we generated transgenic mice producing a green fluorescent Beclin 1 protein (Beclin 1-GFP) under Beclin 1 endogenous regulation. The beclin 1-GFP transgene is functional because it completely rescues early embryonic lethality in beclin 1-deficient mice. The transgenic mice appear normal, with undetected change in basal autophagy levels in different tissues, despite the additional expression of functional Beclin 1-GFP. Staining of Beclin 1-GFP shows mostly diffuse cytoplasmic distribution in various tissues. Detailed analysis of the transgene expression by flow cytometry reveals a Bcl-2-like biphasic expression pattern in developing T and B cells, as well as differential regulation of expression in
Scott RC, et al. (2007) Direct induction of autophagy by Atg1 inhibits cell growth and induces apoptotic cell death. Curr Biol 17(1):1-11 BACKGROUND: To survive starvation and other forms of stress, eukaryotic cells undergo a lysosomal process of cytoplasmic degradation known as autophagy. Autophagy has been implicated in a number of cellular and developmental processes, including cell-growth control and programmed cell death. However, direct evidence of a causal role for autophagy in these processes is lacking, resulting in part from the pleiotropic effects of signaling molecules such as TOR that regulate autophagy. Here, we circumvent this difficulty by directly manipulating autophagy rates in Drosophila through the autophagy-specific protein kinase Atg1. RESULTS: We find that overexpression of Atg1 is sufficient to induce high levels of autophagy, the first such demonstration among wild-type Atg proteins. In contrast to findings in yeast, induction of autophagy by Atg1 is dependent on its ...

A New Chapter of the Mormon War-The Mule Contract. From the St. Louis Democrat, 18th. We learn that the Board of Inquiry, which met at Fort Leavenworth to investigate the complaints made by the contractors against Capt. VAN VLIET, A. Q. M., in relation to his inspection and appraisement of the mules, have presented a report signed by Col. ROBERTS and Major GAINES, condemning the conduct of VAN VLIET, and justifying the complaints of the contractors. The report, we understand, affirms that mules were improperly rejected, and that the general appraisement should not have been less than $185 a head. Major SHERMAN does not, it seems, concur in this, and the presumption is that he will present a minority report under his own signature. The number of mules received by VAN VLIET from the favored few in compliance with his orders was 3,718. The increased appraisement of the Board of Inquiry will add $50,000 to the profits. The acceptance of the rejected mules will swell the figures still more. Mr. ...
TY - JOUR. T1 - Delphinidin induces necrosis in hepatocellular carcinoma cells in the presence of 3-methyladenine, an autophagy inhibitor. AU - Feng, Rentian. AU - Wang, Shiow Y.. AU - Shi, Ying Hong. AU - Fan, Jia. AU - Yin, Xiao-Ming. PY - 2010/4/14. Y1 - 2010/4/14. N2 - The present study was performed to determine whether anthocyanins could trigger different modes of cell death in different cancers. It was found that whereas cyanidin-3-rutinoside and delphinidin could induce apoptosis in leukemia cells, they caused growth retardation in hepatocellular carcinoma cells (HCC), which was accompanied with a significant cellular vacuolization. The latter was likely caused by macroautophagy and was completely suppressed by 3-methyladenine, an inhibitor of class III phosphoinositide 3-kinase that is important for autophagy activation, and by bafilomycin A1, which blocks lysosomal degradation. Delphinidin induced significant lipidation of LC3, an indication of macroautophagy, which was also suppressed ...
To maintain cellular homeostasis, eukaryotes must control the function, quality and quantity of organelles through organelle degradation. The removal of damaged organelles is essential for plants throughout various developmental stages as well as to overcome environmental changes that enhance cellular damage, since organelle degradation allows the recycling of derived small molecules, such as amino acids, lipids and nucleic acids. During developmental aging or starvation, plants actively degrade organelles in old organs and reuse the released molecules to produce juvenile organs. This nutrient recycling can determine crop productivity under agricultural settings since various nutrients are mobilized from vegetative organs to seeds during grain filling of cereals. Overall, various types of organelle turnover systems must cooperate throughout plant development to complete their life cycle. Autophagy is the
Given the diversity of autophagy targets and regulation, it is important to characterize autophagy in various cell types and conditions. We used a primary myocyte cell culture system to assay the role of putative autophagy regulators in the specific context of skeletal muscle. By treating the cultures with rapamycin (Rap) and chloroquine (CQ) we induced an autophagic response, fully suppressible by knockdown of core ATG genes. We screened D. melanogaster orthologs of a previously reported mammalian autophagy protein-protein interaction network, identifying several proteins required for autophagosome formation in muscle cells, including orthologs of the Rab regulators RabGap1 and Rab3Gap1. The screen also highlighted the critical roles of the proteasome and glycogen metabolism in regulating autophagy. Specifically, sustained proteasome inhibition inhibited autophagosome formation both in primary culture and larval skeletal muscle, even though autophagy normally acts to suppress ubiquitin ...
Omegasome is a cell compartment consisting of lipid bilayer membranes enriched for phosphatidylinositol 3-phosphate (abbreviated PI(3)P or PtdIns3P) and related to a process of autophagy. It is a subdomain of the endoplasmic reticulum (ER) membrane and has a morphology resembling Greek capital letter omega (Ω). Omegasomes are the sites from which phagophores form. Phagophores (also called isolation membranes) are sack-like structures that mature into autophagosomes that fuse with lysosomes in order to degrade the contents of the autophagosomes. The formation of omegasomes is increased as a response to starvation. Autophagy (from Greek words for self and eating) is a process of digesting or degrading cytoplasmic molecules (proteins, lipids, sugars and organelles). Macroautophagy is the main autophagic pathway, used primarily to eradicate damaged cell organelles such as mitochondria, ribosomes, etc. The omegasome is present at the opening of the sack-like phagophore while items destined for ...

Autophagy is a cellular process mediating degradation of bulk cytoplasm, long-lived proteins and entire organelles. In this process, double-membrane vesicles, the autophagosomes, wrap around portions of cytosol and transport them to the lysosome for degradation. Several molecules participate in autophagosome nucleation and elongation, including various components of the class III PI3K complex, such as Beclin 1 and Ambra1 (. Activating Molecule in Beclin 1-Regulated Autophagy), which has been recently characterized in our laboratory (1, 2). Any genetic or pharmacological alteration in this process impairs the cell survival rate or cell metabolism, thereby affecting tissue homeostasis (3). Many neurodegenerative conditions, for example, can be traced back to defective autophagy and autophagy has also been identified as a crucial process in oncogenesis and cancer progression. Several autophagy-related proteins have tumor suppressor activity (Beclin 1, Atg5, Bif-1, Atg4C, UVRAG) and some autophagy ...
The interest on autophagy, an evolutionarily conserved process in eukaryotes, has enormously increased in the last years, since the malfunctioning of autophagy is involved in many diseases such as cancer or neurodegenerative states. Autophagosome formation is the key process in autophagy. Despite extensive work, the model of autophagosome formation is not yet fully established. Some important questions remain to be elusive, such as where the bona fide marker protein of autophagosome, LC3, is lipidated, how lipidated LC3 functions in autophagosome formation, and how the proteins for LC3 lipidation and delipidation are involved in autophagosome formation.. Although genetic approaches have been powerful to dissect autophagosome formation process, intrinsic limitations include the lack of acute manipulation in protein activity. We will prepare semi-synthetic LC3 and lipidated LC3 proteins and use them to monitor dynamics of autophagosome formation in vitro and in cells. The semi-synthetic LC3 ...
Macroautophagy is a non-selective, bulk degradation process conserved in eukaryotes. Response to starvation stress and/or regulation of nutrient breakdown/utilization is the major intracellular function of macroautophagy. Recent studies have revealed requirement for autophagy in diverse functions such as nutrient homeostasis, organelle degradation and programmed cell death in filamentous fungal pathogens, for proper morphogenesis and differentiation during critical steps of infection. In this review, we aim to summarize the physiological functions of autophagy in fungal virulence, with an emphasis on nutrient homeostasis in opportunistic human fungal pathogens and in the rice-blast fungus, Magnaporthe oryzae. We briefly summarize the role of autophagy on the host side: for resistance to, or subversion by, the pathogens.
The hallmark of an immune response to Mycobacterium tuberculosis is granuloma formation. CD4+Th1 cells are of central importance in anti-mycobacterial immunity by way of producing effector IFN-γ and TNF-α cytokines that help to contain infection in the granulomas by activating macrophages. The environment of the granuloma is hypoxic and we have little knowledge on CD4+ T cell processes and function in this environment. Autophagy is a de novo intracellular protein and organelle degradation pathway induced in eukaryotic cells by stress-factors such as starvation or hypoxia. It has been described that autophagy is induced in T cells upon activation and autophagic processes might contribute to nutrient supply and the regulation of cytokine production in T cells. The aim of this study was to investigate autophagic processes in CD4+ T cells after activation and the regulation of IFN-γ production under normoxia, and hypoxia as found in the granuloma of TB patients. The main assays, immunoblotting ...
Fiber cells are among the longest lived cells in the body. Based on its expression pattern and putative antiapoptotic role in other systems, we hypothesized that Livin might contribute to lens cell longevity by suppressing cell death in the hypoxic core of the tissue. Alternatively, Livin, which is expressed by cells as they approach the OFZ (Fig. 7C), might have a role in organelle degradation. To test these hypotheses directly, we generated mice carrying a floxed Birc7 allele (see Supplementary Fig. S1), Birc7flox/flox mice were crossed with either LeCre16 or MLR1017 mice to conditionally delete Birc7 in the lens. The LeCre and MLR10 strains express Cre recombinase in lens and have been widely used to conditionally delete genes in this tissue. The two strains differ primarily in the timing of the onset of lens Cre expression (E8.75 for LeCre and E10.5 for MLR10). Since our data suggested that Livin expression does not commence until after E12.5 (Fig. 3B), we anticipated that the efficacy of ...

We thank Rubinsztein and Nixon (1) for their interest in our study (2). We have the greatest respect for their contributions to the field of autophagy.. In our paper, we reported the discovery of compounds with related structures that stimulate autophagy in primary neurons by a pathway that is independent of the mammalian target of rapamycin (mTOR) (2). The lead compound mitigates against toxicity in two models of neurodegeneration (2). Using one conventional assay, the most potent compound in that series induced autophagy at least fivefold. Subsequently, we found analogs that induce autophagy 10-fold. Although not the focus of our study, we offered an assessment of the efficacy of rapamycin and said that it induces autophagy weakly, if at all, in primary neurons.. Using similar assays of autophagy, Boland et al. (3) reported a twofold induction by rapamycin in neurons and described it as robust. The appropriate adjective to describe the strength of an induction is admittedly subjective. ...

During development of the lens, epithelial cells at the lens equator begin a differentiation process to become secondary fibre cells. The differentiating cells elongate and migrate towards the centre of the lens where they envelop the older, central fibre cells. Differentiation into fibre cells is accompanied by the breakdown of all organelles, such as the mitochondria. All organelle degradation is completed and denucleation occurs at the border of the organelle free zone (OFZ) which contains the central, terminally differentiated, fibre cells. The differentiation pathway is not well characterised, though it is believed to have similarities to an attenuated form of apoptosis supported by the identification of apoptosis related genes, such as TNF, in the lens. This study continues the search for and characterisation of apoptosis related genes expressed during lens development, focusing on TNFs and their extended family. Reverse Transcriptase-(RT-) PCR was carried out, identifying a number of TNF ...
