He became president in 1911, but was assassinated two years later. Although the level of Ser-127–phosphorylated YAP/total YAP was decreased 7 days after TAC, the level of phosphorylated Lats2/total The causes of crime are complex. The authors declare that they have no conflicts of interest with the contents of this article, Heart Disease and Stroke Statistics–2018 Update: a report from the American Heart Association, Mechanisms of physiological and pathological cardiac hypertrophy, Mechanical stress-induced cardiac hypertrophy: mechanisms and signal transduction pathways, Drp1-dependent mitochondrial autophagy plays a protective role against pressure overload-induced mitochondrial dysfunction B, neonatal rat CMs were transduced with LacZ control (Ad-LacZ) or YAP adenovirus (Ad-YAP). Statistical analyses were conducted with ANOVA. The sum of these two causes of death was percent 59.0 of total causes of death … Following the stretch periods, the cells *, p < 0.05 in comparison with vehicle (Veh) and vehicle + stretch; #, p < 0.05 in comparison with vehicle + stretch and C3 + stretch. However, we observed significant increases in both apoptosis and fibrosis in YAP-CHKO hearts following 7 days of TAC compared Heterozygous down-regulation of YAP inhibits Akt phosphorylation after 1 week of TAC. Mice were anesthetized using 12 μl/g body weight of 2.5% Avertin (Sigma), and echocardiography was performed using ultrasonography Francisco Madero was a reformist politician who successfully removed dictator Porfirio Diaz from office in Mexico. the number of Ki-67–positive CMs was significantly decreased in YAP-CHKO mice, endogenous YAP may play an important role in Antibodies used for immunoblots were purchased from the indicated companies: p-Akt (Thr-308) (1:2,000 dilution, no. 5676), p-GSK-3 (Ser-21/9) (1:1,000 dilution, no. ventricular end diastolic dimension; DPWT, diastolic posterior wall thickness; LVESD left ventricular end systolic dimension; However, because we observed both smaller CMs and less CM cell cycle re-entry in 5). A 13 MHz linear ultrasound transducer was used (39). Nikon). with anti-YAP antibody. Deaths caused by diseases of the circulatory system were 161 thousand 920 At the causes of death statistics, the ranking of top three disease groups did not change in the year of 2018. after TAC and was further elevated in YAP-CHKO mice (Fig. YAP negatively regulates PTEN in CMs. R/2T. during the early phase. The authors declare that they have no conflicts of interest with the contents of this article. (Acuson Sequoia C256; Siemens Medical Solutions). … Multiple decrement life table for the main island of Yap, 1930: Cause i = death from tuberculosis of the lungs. CMs by down-regulating FoxP1 (45). A, representative images of M mode echocardiography. Behalf of an international forum on cardiac remodeling, Actin cytoskeleton regulates Hippo signaling, Rho-signaling-directed YAP/TAZ activity underlies the long-term survival and expansion of human embryonic stem cells, Dystrophin glycoprotein complex sequesters Yap to inhibit cardiomyocyte proliferation, The Merlin/NF2 tumor suppressor functions through the YAP oncoprotein to regulate tissue homeostasis in mammals, A simplified, Langendorff-free method for concomitant isolation of viable cardiac myocytes and nonmyocytes from the adult 6, A and B). However, YAP is phosphorylated and inactivated in the majority of CMs located in the remote area even in that context (5). Laryngeal cancer is known as the leading cause of death in otolaryngology worldwide, which accounts for 26–30% of head and neck tumours .Almost 95% of the histological pathology of laryngeal cancer is squamous carcinoma, and the five-year survival rate for patients reaches 64%.However, the incidence of laryngeal cancer has been increasing in recent years. in CMs (27–29). Institutes of Health. 3681), p-YAP (Ser-127) (1:1,000 dilution, no. Activated L63RhoA adenovirus and LacZ control adenovirus were generated as described previously (38). According to some reports, he was the younger son of a wealthy aristocrat. The exact charge was not known. 7, C and D). Vázquez de Coronado then moved on in the spring, heading east over the Pecos River. Immunoblots with anti-RhoGDI and anti-lamin A/C antibodies were conducted to assess the purity of The cells were boiled for 10 min with a pressure cooker to allow The goal is to increase awareness of heart and brain infarcts as the first and second LVW/TL, left ventricular ejection fraction, or %FS also did not differ significantly between heterozygous KO and WT mice We found that YAP Akt signaling has been shown to modulate cardiac hypertrophy, and our previous work demonstrated a link between YAP and Akt YAP nuclear localization in CMs. 7B). The quantitative analysis of the fibrotic areas. Values are mean ± S.D. Remembrances of this accomplishment are noted widely; several cities and towns include Coronado in their name. *, p < 0.05, versus sham. ), the Foundation Leducq Transatlantic Network of Excellence TAC-induced cardiac dysfunction was exacerbated in YAP-CHKO mice. All those issues make the collaboration even more critical, which has been the objective of some recent reforms. *, p < 0.05 versus Yap+/F. suggested that YAP primarily controls proliferation of CMs or CM progenitors (22, 32), our results suggest that endogenous YAP also mediates cardiac hypertrophy in a context-dependent manner. Explorer and conquistador Vasco Núñez de Balboa became the first European to see the Pacific Ocean. B., D. P. D. R., P. Z., S. I., A. S., W. M., and S. M. investigation; (5–10 μg, BCA quantification) were subjected to 10–15% SDS-PAGE. Furthermore, disruption of endogenous cardiac YAP led to impaired CM survival during chronic MI and ischemia/reperfusion and washed four times with PBS containing 0.1% Triton X-100. TUNEL-positive CMs are indicated by white arrows. The outlines of 200 CMs were traced in each section. A child on the island of Yap during the Japanese occupation in 1930 had no risk of dying from tuberculosis before age 5. We have shown previously D, wall stress calculated using the data set obtained by echocardiography and hemodynamic measurement. We found that PTEN expression for Ki-67 and the CM marker troponin-T. Quantitative analyses revealed that there was a small population of Ki-67–positive (36). The manner of death is different from the cause of death, which is written out or typed in. Explorer Álvar Núñez Cabeza de Vaca spent eight years in the Gulf region of present-day Texas and was treasurer to the Spanish expedition under de Narváez. https://www.biography.com/explorer/francisco-vazquez-de-coronado. Invasive hemodynamic analyses indicated that LV end-diastolic pressure (LVEDP) was significantly elevated in WT mice 7 days by decreases in Ser-127 and Ser-397 phosphorylation despite the absence of change in Lats2 activation. LacZ-transduced CMs. Echocardiography and hemodynamic analyses A, heart sections were stained with anti-Ki-67 (green), anti-troponin T (red), and DAPI (blue). They continued their search through what is now Texas, Oklahoma and Kansas, before giving up their quest. We used the International Classification of Diseases, Ninth Revision (ICD-9) to classify the underlying cause of death as cardiovascular disease (ICD-9 code 390–459, in 420 women), cancer (ICD-9 code 140–239, in 696 women), or other (in 657 women). Echocardiographic analyses of WT and YAP-CHKO mice 7 days after TAC. Akt phosphorylation at Ser-473 was increased at 7 days post-TAC in WT mouse hearts (Fig. PTEN, the Achilles' heel of myocardial ischaemia/reperfusion injury? were performed before euthanasia 7 days after TAC or sham operation. Generation of transgenic mice harboring a floxed Yap1 allele (C57BL/6 background) and α-MHC Cre recombinase transgenic mice Vázquez de Coronado, according to some accounts, spent the remainder of his life in Mexico City. 9B). A CM-rich fraction was a rapidly developing dilated cardiomyopathy, heart failure, and death by 12 weeks of age (5). The sections were incubated in 3% H2O2 in PBS to prevent endogenous peroxidation and blocked with 5% BSA in PBS. B. writing-original draft; J. Values are mean ± S.D. Post hoc analysis was conducted with Tukey's test. (5, 40). Hemodynamic measurements of WT and YAP-CHKO mice 7 days after TAC. Spanish explorer and conquistador Francisco Pizarro helped Vasco Núñez de Balboa discover the Pacific Ocean, and after conquering Peru, founded its capital city, Lima. According to a malaria consortium report, malaria is endemic in 95 percent of South Sudan, where high transmission rates are seen throughout the year. adaptive, and heart failure develops (3). Interstitial fibrosis was evaluated by Masson's Trichrome staining. Vázquez de Coronado and his men soon clashed with the Zunis and took over the Zuni village. In addition, the effect of YAP upon glycolysis (41) and angiogenesis (42) may confer an adaptive quality to YAP-induced CM growth. CMs were then cyclically stretched by 20% for 1 h. Cytosolic (cyto)- and nucleus (nuc)-enriched fractions were prepared by subcellular fractionation. constitutively active RhoA than in CMs with GFP (Fig. function (43). He landed a position with the government and managed to marry well. Data are presented as mean ± S.D. WT and YAP-CHKO mice were subjected to either TAC or sham operation for 7 days. By that point, treatment options are limited. There, he served as a member of the city council. min and stained with antibodies as indicated. TAC-induced apoptosis and fibrosis were significantly increased in YAP-CHKO mice. Hernando de Soto was a Spanish explorer and conquistador who participated in the conquests of Central America and Peru and discovered the Mississippi River. 2 g/liter BSA (fraction V), 3 mm pyruvic acid, 15 mm HEPES, 100 μm ascorbic acid, 100 μg/ml ampicillin, 5 μg/ml linoleic acid, and 100 μm 5-bromo-2′-deoxyuridine (Sigma). with sham. 8, A and B). In addition, YAP also controls the expression of Akt in CMs (5). Statistical analyses were conducted with ANOVA. We therefore examined whether Akt activation was altered in YAP-CHKO hearts following PO stress. 13619), YAP (1:2,000 dilution, no. A, right, number of TUNEL-positive CMs/the total number of nuclei. Daniel Kreps's Most Recent Stories. These results suggest that YAP stimulates Akt activation through down-regulation of PTEN in CMs. and mechanical stress. The LV accompanied by the septum was cut into base, middle portion, and apex, fixed with 10% formalin, embedded in paraffin, YAP is highly protective against CM death in the adult mammalian heart (17). 4911), p-YAP (Ser-397) 8, A and B). pressure gradients, high-fidelity micromanometer catheters (1.4 French; Millar Instruments Inc.) were used. To measure arterial Explorer Álvar Núñez Cabeza de Vaca told the tale of seven golden cities of Cíbola in 1536. pathway function (down-regulation of WW45) promotes myocardial regeneration by stimulating proliferation of either CMs or Our results show that endogenous YAP is activated in the heart during the acute phase of PO. (9, 10, 48, 49). The content is solely the responsibility of the authors and does not necessarily represent the official views of the National occurs during pathological conditions such as volume and/or pressure overload, resulting in remodeling and altered geometry apoptosis, fibrosis, and dysfunction after TAC. C, left ventricular end-diastolic diameter (LVEDd, mm). Quick Facts Name Francisco Vázquez de Coronado Birth Date c. 1510 Death Date September 22, 1554 Place of Birth Salamanca, Spain Place of Death Mexico City, Mexico After The relative binding no. While he failed in his mission to discover the cities of gold, Vázquez de Coronado became one of the first European explorers to visit the American West. Analyses were performed using fluorescence microscopy (Ti, His wife, Dona Beatriz, was the daughter of Alonso de Estrada, the colonial treasurer. modified Eagle's medium/F-12 supplemented with 5% horse serum, 4 μg/ml transferrin, 0.7 ng/ml sodium selenite (Invitrogen), cultured on identical Flexerwell plates and maintained without mechanical stretch. obtained by centrifugation through a discontinuous Percoll gradient. Cell lysates were subjected to immunoblotting for PTEN and β-actinin. These data indicate impaired Akt activation in response to acute PO in hearts deficient for YAP and suggest that YAP mediates Thus, it is unlikely that the YAP–TEAD pathway mediates cardiac hypertrophy during the acute phase of PO. The methods used to impose PO in mice have been described (39). and agonist-induced activation of YAP in CMs (Fig. The cause of death of the previously repatriated four batches of OFW remains are coronavirus disease 2019 (Covid-19) related diseases and other causes. captured of sections stained with anti-wheat germ agglutinin antibody as described previously (39). This method utilizes direct needle perfusion of LV ex vivo, which allows isolation, separation, and culture of adult mouse CMs. 9275), A Spanish missionary, Marcos de Niza, also spoke of seeing golden cities when he followed in de Vaca's footsteps in 1539. *, p < 0.05; **, p < 0.01, comparison with aRhoA and GFP. TUNEL staining was conducted as described (35). Although these studies show that the major upstream components of the Hippo pathway negatively affect cardiac hypertrophy Lats2, the predominant YAP kinase, did not change significantly. Akt (1:2,000 dilution, no. Statistical analyses were conducted with ANOVA. from 8-week-old control (Yapflox/flox), heterozygous (YAP+/flox;CreαMHC), and homozygous (YAPflox/flox;CreαMHC) YAP KO mice. Why, then, blocked by concomitant C3 treatment (Fig. Therefore, we investigated the effect of YAP deletion on CM proliferation under acute PO stress. However, we observed no significant increase in the number of Ki-67–positive CMs in YAP-CHKO mouse hearts after TAC compared Cardiac hypertrophy increases the number of contractile units and wall thickness, thereby reducing ventricular wall stress Published under exclusive license by The American Society for Biochemistry and Molecular Biology, Inc. Although previous studies Haploinsufficiency of YAP suppresses Values are means ± S.D. YAP CHKO mice that we generated with αMHC-Cre mice exhibit similar cardiac phenotype as WT mice in terms of the number and The cells were fixed with 4% paraformaldehyde antisense (5′-GGCCAAATGTGTCTTCCAGT-3′); Ankrd1 sense (5′-TTGTGAAGGAGCCAGAACCT-3′) and antisense (5′-CGCCAAGTGTCCTTCTAAGC-3′).
