Apoptosis - Wikipedi

  1. Apoptosis (from Ancient Greek ἀπόπτωσις, apóptōsis, falling off) is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes and death.These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global [vague] mRNA decay
  2. To show the derivation clearly, the authors proposed that the stress should be on the penultimate syllable, with the second half of the word being pronounced like ptosis with a silent p, which comes from the same root to fall and is used in medicine to describe drooping of the upper eyelid
  3. He suggested apoptosis, which translates to falling off, or falling away, and is used to describe autumn leaves falling from the branch, or flower petals drifting to earth. In Greek, the second p in apoptosis is silent, so the pronunciation is ay-paw-TOEsis
  4. Finally, the Oxford English Dictionary shows that in 1994, the esteemed journal Nature sided with the apop-tosis pronunciation, calling the silent P neither correct nor attractive, because if I'm reading this right, when the Greek pt combination appears in the middle of a word, the P usually is pronounced
  5. Apoptotic cells express special cell surface molecules, leading to their quiet removal by neighboring phagocytes. In contrast, necrotic cells generally are not removed as intact cells and often cause inflammation (Vallance et al., 1997)
  6. Apoptosis is partly responsible for keeping many things (like your organs) the right size, the right shape, in the right place, and functioning correctly. You may hear this word pronounced..

To show the derivation clearly, we propose that the stress should be on the penultimate syllable, the second half of the word being pronounced like ptosis (with the p silent), which comes from the same root to fall and is already used to describe drooping of the upper eyelid Apoptosis culminates in the breakdown of the nuclear membrane by caspase-6, the cleavage of many intracellular proteins (e.g., PARP and lamin), membrane blebbing, and the breakdown of genomic DNA. How to Pronounce Apoptosis The traditional and most correct pronunciation is the Greek, which features a silent second p: ay-po-TOE-sis, although many people pronounce the word in English as ay-POP-toe-sis. I prefer and use the original pronunciation. Get the eBook for $9.9 The incorrect assumption in the footnote is in proposing that the second p in apoptosis, should be silent. This is wrong for two reasons. Firstly, the Greeks pronounced the π at the start of πτῶσις

Apoptosis (Greek: apo - from, ptosis - falling; commonly pronounced with a silent second p) is a process of deliberate life relinquishment by a cell in a multicellular organism In vivo, this precipitates an elevation in IFN-β levels and consequent hematopoietic stem cell dysfunction, which is corrected by loss of Bak and Bax. Thus, the apoptotic caspase cascade functions to render mitochondrial apoptosis immunologically silent Apoptosis is a form of programmed cell death that occurs in humans, animals and other multi-cellular organisms. Debate continues over the correct pronunciation, with opinion divided between a pronunciation with the second p silent and the second p pronounced,. Apoptosis is a Greek word that translates to falling off or falling away. It's often used to describe the natural world: autumn leaves as they tumble from the branch; flower petals wilting and drifting to earth. In Greek, the second p is silent, and so the traditional and most correct pronunciation is ay-paw-TOE-sis : a genetically directed process of cell self-destruction that is marked by the fragmentation of nuclear DNA, is activated either by the presence of a stimulus or removal of a suppressing agent or stimulus, is a normal physiological process eliminating DNA-damaged, superfluous, or unwanted cells, and when halted (as by gene mutation) may result in uncontrolled cell growth and tumor formatio

Pathogenetic mechanisms of retinal degeneration include cell loss by apoptosis. This gene-regulated mode of single-cell death occurs in a number of widespread human diseases such as neurodegenerati... Apoptosis in the Retina: The Silent Death of Vision | Physiology Login to your accoun Debate continues over the correct pronunciation, with opinion divided between a pronunciation with a silent p (a-PO-tosis), and the p spelt out (a-POP-tosis), but the Greek root has a silent p, like pterodactyl The p is silent. And it is wrong and misleading to say A-poptosis as one so often hears. Doctors are used to words like apraxia, aphasia etc, which indicates a negative condition. But there is no such thing as a Poptosis, so you cannot have a lack of it Apoptosis, in biology, a mechanism that allows cells to self-destruct when stimulated by the appropriate trigger. Apoptosis can be triggered by mild cellular injury and by various factors internal or external to the cell; the damaged cells are then disposed of in an orderly fashion. As

Apoptosis, Pyroptosis, and Necrosis: Mechanistic

Furthermore, nicotine treatment significantly (P < 0.05) attenuated the HFD-induced decrease in fibroblast growth factor 21 (FGF21) and silent information regulator 1 (SIRT1). We conclude that nicotine, when combined with HFD, triggers CM apoptosis through the generation of oxidative stress and inactivation of AMPK together with the activation. The idea that which apoptosis is the main mechanism of the cell death during induced or hereditary retina degeneration was formulated in the first decade of the 2000s [22,25,[53][54][55]

Apoptosis (/̩æ.pəpˈtō.səs/) In English, the p of the Greek -pt-consonant cluster is typically silent at the beginning of a word (e.g. pterodactyl), but articulated when used in combining forms preceded by a vowel, as in helicopter or the orders of insects:. To show the derivation clearly, we propose that the stress should be on the penultimate syllable, the second half of the word being pronounced like "ptosis" (with the "p" silent), which comes from the same root "to fall", and is already used to describe the drooping of the upper eyelid sclero dines The present study aimed to identify whether microRNA (miRNA/miR)‑34a regulates the proliferation and apoptosis of gastric cancer cells by targeting silent information regulator 1 (SIRT1). The expression of miR‑34a and SIRT1 and cell viability was investigated in gastric cancer cells. Reverse transcription‑quantitative polymerase chain.

The exposure of phosphatidylserine (PS) on the outer plasma membrane has long been considered a unique feature of apoptotic cells. Together with other eat me signals, it enables the recognition and phagocytosis of dying cells (efferocytosis), helping to explain the immunologically-silent nature of apoptosis. Recently, however, PS exposure has also been reported in non-apoptotic forms of. Apoptosis (from Ancient Greek ἀπόπτωσις falling off) is a form of programmed cell death that occurs in multicellular organisms. Biochemical events lead to characteristic cell changes and death.These changes include blebbing, cell shrinkage, nuclear fragmentation, chromatin condensation, chromosomal DNA fragmentation, and global mRNA decay. . The average adult human loses between 50. The word apoptosis comes from Greek. When Australian scientist John Kerr first used the word in 1972, he said that people should say the word with the second p almost silent. Kind of like Ah-puh-TOH-sis. But over time, other pronunciations have come about. Apoptosis is a word that is more likely to be read than spoken If we could get apoptosis levels back up, The traditional and most correct pronunciation is the Greek, which features a silent second p: ay-po-TOE-sis, although many people pronounce the word in English as ay-POP-toe-sis. I prefer and use the original pronunciation

  2. To show the derivation clearly, we propose that the stress should be on the penultimate syllable, the second half of the word being pronounced like ptosis (with the p silent), which comes from the same root to fall, and is already used to describe the drooping of the upper eyelid sclero dines
  3. In contrast to prior belief, tumor cell apoptosis is not necessarily silent but can be immunogenic. By tracing how anthracyclines and γ-irradiation trigger immunogenic cell deaths, we found that they were causally connected to the exposure of calreticulin on the tumor cell surface, before apoptosis in the tumor cell itself occurred. Furthermore, we showed that calreticulin exposure was.
  4. Vascular smooth muscle cells (VSMCs) are the main structural cell of blood vessels, and VSMC apoptosis occurs in vascular disease, after injury, and in vessel remodeling during development. Although VSMC apoptosis is viewed as silent, recent studies show that apoptotic cells can promote apoptosis-induced compensatory proliferation (AICP), apoptosis-induced apoptosis (AIA), and migration of.
  5. Apoptosis is a Greek word. My Greek friend says it is pronounced aPOPtosis. level 2. Oh, I just realized it starts with a silent P and I missed the joke. level 1-1 points · 7 months ago. The people who named the phenomenon clearly stated in their paper that the p is silent so yeah, pocorn

John F. Kerrand colleagues (1972) coined the term apoptosis (a-po-toe-sis; second P is silent), Greek word for the process of leaves falling from trees or petals falling from flowers. [4] Wyllie described the first and the most dramatic DNA fragmentation in 1980 Abstract. Apoptosis is a highly regulated process of cell death with characteristic morphological changes that are distinct from necrosis. The biochemical machinery responsible for apoptotic cell death appears to be constitutively expressed in most, if not all, cells and can be triggered by a variety of signals, including sustained increases in the intracellular Ca 2+ level Although MOMP is critical for intrinsic apoptosis, caspases are not, as typically cells die post‐MOMP in the absence of caspase activity. Caspases appear to function primarily to accelerate cell death—this serves important functions during development and keeps apoptosis immunologically silent [[14-17]] Apoptotic versus necrotic cell death: Apoptosis is an energy-dependent silent form of cell death that does not create an inflammatory reaction in the surrounding tissue, in contrast to necrosis. During apoptosis, the cell membrane remains intact for a long time. However, at the onset of apoptosis, the cell membrane characteristically looses its.

How to Pronounce 'Apoptosis' Grammar Gir

The demonstration that apoptosis releases active molecules rather negates the idea of apoptosis as a 'silent' mechanism of deleting cells. However, apoptotic cells that are not rapidly phagocytosed will begin to release inflammatory cytokines as they undergo secondary necrosis. This release of inflammatory cytokines will result in the. Apoptosis is a well described mechanism of cell death, in which mitochondria play a central role. It has long been known that apoptosis is an immunologically silent form of cell death, but the molecular basis of this remains largely unknown. Using mice with genetic deficiencies in the apoptotic machinery, we are uncovering a variety of. Click on the article title to read more 1994 Nature 28 Sept. 98/2 The 'p' in ptosis is silent, and on that basis students are commonly exhorted to pronounce apoptosis as apo'tosis The silent 'p', however, appears neither correct nor attractive in words in which the Greek-derived 'pt' occurs in the middle of a composite word Marina Rascio Henriques Dutra, Regiane dos Santos Feliciano, Kalil Ribeiro Jacinto, Telma Luciana Furtado Gouveia, Eduardo Brigidio, Andrey Jorge Serra, Mariana Morris, Maria da Graça Naffah-Mazzacoratti, José Antônio Silva, Protective Role of UCP2 in Oxidative Stress and Apoptosis during the Silent Phase of an Experimental Model of Epilepsy Induced by Pilocarpine , Oxidative Medicine.

Apoptosis: the quiet death silences the immune system

Hi Rick, I don't go for either of those: The two greek stems in apoptosis are apo (away or off) and ptosis (falling). Looking at other english words similarly constructed from greek, I'd expect the p in ptosis to be pronounced, after the o in apo (as in helicoPter - not often pronounced helicoater or helicotter, and all of those winged insect words like coleoPtera) The results were expressed as a ratio relative to the value obtained in control cells. (B) Cell proliferation was detected by an MTT assay. *P<0.05 and **P<0.01, as indicated. SIRT, silent mating type information regulation 2 homolog; mTOR, mammalian target of rapamycin; S6K1, S6 kinase β-1; p-, phosphorylated Nutrient deprivation is a likely contributor to intervertebral disc (IVD) degeneration. Silent mating type information regulator 2 homolog 1 (SIRT1) protects cells against limited nutrition by modulation of apoptosis and autophagy. However, little evidence. Then, knockdown of G6PD observably facilitated cell apoptosis in both MGC-803 and AGS cells (P < 0.01, Fig. 2c). As for the glycolysis progression, silent of G6PD expression notably reduced the glucose utilization, lactate concentrations, and ATP production in both AGS and MGC-803 cells (P < 0.01, Fig. 2d-f)

Apoptosis is thus thought to be a critical factor mediating these cell death although the molecular basis remains unclear. Silent Information Regulator 2 (Sir2), a recently identified as NAD-dependent histone deacetylase, has an ability to deacetylate p53, resulting in the prevention of cellular senescence and apoptosis induced by oxidative stress To understand the linkage between the mitochondria and the process of apoptosis we should look at the pathways to cell death and the see where ATP is required to complete it in any of four mechanisms. Remember that ATP is an important product of t.. apoptosis An intrinsic, highly complex programme of auto-orchestrated cell death, which is as complex and important as proliferation. Apoptosis is morphologically characterised by chromatin condensation and DNA degradation, and is a mechanism used by the immune system for antigen-induced clonal deletion of cortical thymocytes (i.e., immune tolerance) The process of programmed cell death, or apoptosis, is generally characterized by distinct morphological characteristics and energy-dependent biochemical mechanisms. Apoptosis is considered a vital..

p73, the first homologue of the tumour suppressor protein p53, was recently discovered on chromosome 1p36 and has been shown to induce apoptosis in a p53-like manner. The present study was performed with the aim of investigating the expression of p53,. To our knowledge there are two main pathways to inhibit p53 activity, by deacetylation or by expression of the anti-apoptotic Bcl-2 family proteins (James and Green, 2004). Members of the evolutionarily conserved silent information regulator 2 (Sir2) protein family are nicotinamide adenine dinucleotide-dependent histone deacetylases

Breast cancer is one of the most common types of malignancy worldwide; however, its underlying mechanisms remain unclear. In the present study, we investigated the roles of G-protein-coupled receptor family C, member 5, group A (GPRC5A) in cell apoptosis in triple-negative breast cancer (TNBC). The expression of GPRC5A in breast cancer cell lines was detected by real time PCR and western blot Therapies that target histone deacetylases (HDACs) may induce apoptosis and stop disease progression. Silent mating type information regulation 2 homolog 1 (SIRT1) is known to contribute to the development of hematologic malignancies. SIRT1 inhibitors have been studied for antitumor activity in cells from solid tumors

Necroptosis, pyroptosis and apoptosis: an intricate game

Nutrient deprivation is a likely contributor to intervertebral disc (IVD) degeneration. Silent mating type information regulator 2 homolog 1 (SIRT1) protects cells against limited nutrition by modulation of apoptosis and autophagy. However, little evidence exists regarding the extent to which SIRT1 affects IVD cells. Therefore, we conducted an in vitro study using human IVD nucleus pulposus. @article{osti_22687822, title = {Silent information regulator 1 (SIRT1) ameliorates liver fibrosis via promoting activated stellate cell apoptosis and reversion}, author = {Wu, Yuting and Liu, Xuejiao and Zhou, Qun and Huang, Cheng and Meng, Xiaoming and Xu, Fengyun and Li, Jun}, abstractNote = {SIRT1 (silent information regulator 1), a conserved NAD +-dependent histone deacetylase, is closely. Silent information regulation 2 homologue-1 (SIRT1) is an NAD-dependent deacetylase that plays the key roles in multiple cellular processes, including cell cycle, metabolism, autophagy, and apoptosis [22-24] The following cell experiments showed that by activating Bax and blocking the protein activity of Bcl-2, miR-296-5p mimic inhibited proliferation yet accelerated apoptosis in cancer cells (p<0.001, Figure 8A-I). However, up-regulation of STAT3 produced a completely opposite regulatory effect (p<0.001, Figure 8A-I)

Cells may die from accidental cell death (ACD) or regulated cell death (RCD). ACD is a biologically uncontrolled process, whereas RCD involves tightly structured signaling cascad For millions of years, endogenous retroelements have remained transcriptionally silent within mammalian genomes by epigenetic mechanisms. Modern anticancer therapies targeting the epigenetic machinery awaken retroelement expression, inducing antiviral responses that eliminate tumors through mechanisms not completely understood. Here, we find that massive binding of epigenetically activated. An important feature of apoptosis is the 'silent' resolution of dying cells, prior to their necrotic disintegration; in addition, macrophages that have ingested an apoptotic meal secrete anti‐inflammatory cytokines that serve to further downregulate the inflammatory response [152, 153] Apoptosis is a well described mechanism of cell death, in which mitochondria play a central role. It has long been known that apoptosis is an immunologically silent form of cell death, but the molecular basis of this remains largely unknown Apoptosis has traditionally been called the silent cell death because it does not trigger an inflammatory response, but more recent studies have uncovered evidence of paracrine signals originating from apoptotic cells

Author Summary In order to maintain genome integrity, eukaryotic cells have evolved multiple ways to respond to DNA damage stress. One of the major cellular responses is apoptosis, during which the cell undergoes programmed cell death in order to prevent the propagation of the damaged genome to daughter cells. Although clinical observations and other studies have shown that tissues can differ. The silent phase of the pilocarpine- induced model is characterized by no differentiated pheno- typebutmanymetabolicalterations.Weobservedanincrease in p-AKT in the same period in which UCP2 expression is incremented Apoptosis is a process of cell suicide, the mechanisms of which are encoded in the chromosomes of all nucleated cells. Physiological cell death that removes unwanted cells plays an important role in development, tissue homeostasis and defence against viral infection and mutation. Apoptosis is regulated by complex molecular signalling systems The inactivation of programmed cell death has profound effects not only on the development but also on the overall integrity of multicellular organisms. Beside developmental abnormalities, it may lead to tumorigenesis, autoimmunity, and other serious health problems. Deregulated apoptosis may also be the leading cause of cancer therapy chemoresistance. Caspase family of cysteinyl-proteases. Extracellular nucleotides have been reported to act as a 'find-me' signal in the context of phagocyte recruitment by apoptotically dying cells. A new study now examines the mechanisms of nucleotide release during apoptosis and describes the hemichannel-forming protein pannexin 1 as a crucial player in this scenario

Jeffrey Aronson: When I use a word

There was a trend toward an association between Bcl-2-related protein expression and apoptosis (P = .07). Hypothetically, this paradox may be explained by the occurrence of phenotypically silent genomic events in early disease, which confer a survival or growth advantage on stem cells and their progeny, permitting clonal expansion. Apoptosis is a form of regulated cell death in which activation of specific intracellular serine rich proteases (caspases) leads to DNA cleavage and cell death. Apoptosis is an essential feature of development, and provides a mechanism for tissue remodeling in specific regions such as the interdigital spaces of fingers and toes Activation or reactivation of apoptosis in cancer cells using specific and natural drugs discovered is one of the key alternatives to combat this disease, which occurs in a silent manner and without adverse effects Whether Inhaled agonist anti-Fas antibody induced apoptosis of Fas-FasL interaction leads to silent apoptosis or epithelial cells, upregulation of the fibrogenic cytokine TGF- inflammation, itdepends on the differentiation state and β, and fibrosis after 1-2 weeks in mice [32]. Further studies properties of the target cell population [28], as.

Moreover, we detected the expression changes of apoptosis-associated genes C caspase-3, Bax, and Bcl-2 in transplanted tumors and found that, consistent with the results of cell experiments, miR-485-3p mimic up-regulated the protein levels of C caspase-3, Bax and down-regulated that of Bcl-2 (Fig. 7c, d, p < 0.01), and the mRNA levels of Bax. As for the glycolysis progression, silent of G6PD expression notably reduced the glucose utilization, lactate concentrations, and ATP production in both AGS and MGC-803 cells (P < 0.01, Fig. 2 d-f). These data indicated that knockdown of G6PD inhibits gastric cancer cell proliferation and glycolysis

P53 protein is more frequently mutated in human tumours compared with the other proteins. While the majority of the p53 mutations, especially within its DNA-binding domain, lead to the loss of the wild-type function, there are accumulating data demonstrating that the p53 mutants gain tumour promoting activities; the latter triggers a revitalised interest in functional analysis of the p53 mutants F.B. Rosa, J. Roussey, P. M. Coussens, I. M. Langohr. 2011. Pathology in Practice: Cardiac and Aortic Mineralization in a Holstein Cow with Granulomatous Ileitis. JAVMA, In Press. Progress 01/01/11 to 12/31/11 Outputs OUTPUTS: Apoptosis of infected cells is a critical component of the immune response to viruses and intracellular bacteria. Pathogenic granulocytes (eosinophils and neutrophils) infiltrate airway tissues in asthma and chronic obstructive pulmonary disease. Granulocytes release tissue-toxic and inflammatory mediators, making their removal an important pharmacological goal. Removal is thought to be accomplished through apoptosis followed by engulfment by macrophages. Thus, the molecular mechanisms of granulocyte.

Apoptosis contains cell shrinkage, chromatin condensation and nuclear and cell fragmentation. Apoptosis is a gene directed program. Specially Bcl-2 proteins and p53 genes are connected with its. Inflammatory forms of cell death, such as pyroptosis and necroptosis, can be distinguished from the so-called immunologically silent process of apoptosis [ 28 ]. As described in Fig. 1, meticulous cascades are involved in either pathway and different forms of cell death are furthermore closely interlinked Deposition of aggregated amyloid beta (Aβ) protein is hallmark of Alzheimer's disease, leading to dysfunction and apoptosis of neurons. The isoflavone phytoestrogen compound genistein (Gen) exerts a significant protective effect against Aβ25-35 induced neurotoxicity and mitochondrial damage in rat pheochromocytoma (PC12) cells. However, the mechanisms underlying Gen's rescue remain. Necroptosis is considered a secondary cell death response and is different from other forms of cell death, like, for example, apoptosis, which can be deemed a more silent fashion of cell death. The necroptotic mode of cell death involves massive inflammation, since the neighboring cells are alerted/disconcerted The purpose of the present study is to examine the effects of melatonin on apoptosis and oxidative stress in mouse Leydig cells and to elucidate the mechanisms responsible for these effects. Our results indicated that 10 ng/mL of melatonin significantly promoted cell viability, the ratio of EdU-positive (5-Ethynyl-2′-deoxyuridine) cells, and increased the mRNA expression of proliferating.
