These mechanical forces, as experienced by cells and tissues, are then converted into biochemical signals within the cell, leading to a number of cellular mechanisms being activated, including proliferation, differentiation and migration. If the conversion of mechanical cues into biochemical signals is perturbed in any way, then this can be potentially implicated in chronic disease development and processes such as neurological disorders, cancer and obesity. This review will focus on how the interplay between mechanotransduction, cellular structure, metabolism and signalling cascades led by the Hippo-YAP/TAZ axis can lead to a number of chronic diseases and suggest how we can target various pathways in order to design therapeutic targets for these debilitating diseases and conditions.

  • Ryanodine Receptors Are Part of the Myospryn Complex in Cardiac Muscle Received: 10 March 2017 Matthew A
    www.nature.com/scientificreports OPEN Ryanodine receptors are part of the myospryn complex in cardiac muscle Received: 10 March 2017 Matthew A. Benson1, Caroline L. Tinsley2, Adrian J. Waite 2, Francesca A. Carlisle2, Steve M. Accepted: 12 June 2017 M. Sweet3, Elisabeth Ehler4, Christopher H. George5, F. Anthony Lai5,6, Enca Martin-Rendon7 Published online: 24 July 2017 & Derek J. Blake 2 The Cardiomyopathy–associated gene 5 (Cmya5) encodes myospryn, a large tripartite motif (TRIM)- related protein found predominantly in cardiac and skeletal muscle. Cmya5 is an expression biomarker for a number of diseases afecting striated muscle and may also be a schizophrenia risk gene. To further understand the function of myospryn in striated muscle, we searched for additional myospryn paralogs. Here we identify a novel muscle-expressed TRIM-related protein minispryn, encoded by Fsd2, that has extensive sequence similarity with the C-terminus of myospryn. Cmya5 and Fsd2 appear to have originated by a chromosomal duplication and are found within evolutionarily-conserved gene clusters on diferent chromosomes. Using immunoafnity purifcation and mass spectrometry we show that minispryn co-purifes with myospryn and the major cardiac ryanodine receptor (RyR2) from heart. Accordingly, myospryn, minispryn and RyR2 co-localise at the junctional sarcoplasmic reticulum of isolated cardiomyocytes. Myospryn redistributes RyR2 into clusters when co-expressed in heterologous cells whereas minispryn lacks this activity. Together these data suggest a novel role for the myospryn complex in the assembly of ryanodine receptor clusters in striated muscle. Te unique cytoskeletal organisation of striated muscle is dependent upon the formation of specialised interac- tions between proteins that have both structural and signalling functions1.

As upstream components of the Hippo signaling pathway, WWC proteins activate the Large tumor suppressor (LATS) kinase that in turn phosphorylates Yes-associated protein (YAP) and its paralog Transcriptional coactivator-with-PDZ-binding motif (TAZ) preventing their nuclear import and transcriptional activity. Inhibition of WWC expression leads to downregulation of the Hippo pathway, increased expression of YAP/ TAZ target genes and enhanced organ growth. In mice, a ubiquitous Wwc1 knockout (KO) induces a mild neurological phenotype with no impact on embryogenesis or organ growth. In contrast, we could show here that ubiquitous deletion of Wwc2 in mice leads to early embryonic lethality. Wwc2 KO embryos display growth retardation, a disturbed placenta development, impaired vascularization, and finally embryonic death. A whole-transcriptome analysis of embryos lacking Wwc2 revealed a massive deregulation of gene expression with impact on cell fate determination, 1234567890():,; 1234567890():,; 1234567890():,; 1234567890():,; cell metabolism, and angiogenesis. Consequently, a perinatal, endothelial-specific Wwc2 KO in mice led to disturbed vessel formation and vascular hypersprouting in the retina.

Here we described a relationship between Hippo pathway components and inflammation in healthy subjects. The plasma levels of cytokines and chemokines were used to define their inflammatory profile and classify them as normal, high and low producers of cytokines. Leukocytes from healthy subjects with inflammatory profile expressed the highest levels of MSTS1/MST2, SAV1, LATS1/LATS2, MOB1A/MOB1B and YAP genes. The group that overexpressed Hippo pathway-related genes secreted more IFN-ϒ and IFN-α2.

Malignant tumors develop through multiple steps of initiation and progression, and tumor initiation is of singular importance in tumor prevention, diagnosis, and treatment. However, the molecular mechanism whereby a signaling network of interacting pathways restrains proliferation in normal cells and prevents tumor initiation is still poorly understood. Here, we have reported that the Hippo, Wnt/β-catenin, and Notch pathways form an interacting network to maintain liver size and suppress hepatocellular carcinoma (HCC). Ablation of the mammalian Hippo kinases Mst1 and Mst2 in liver led to rapid HCC formation and activated Yes-associated protein/WW domain containing transcription regulator 1 (YAP/TAZ), STAT3, Wnt/β-catenin, and Notch signaling. Previous work has shown that abnormal activation of these downstream pathways can lead to HCC. Rigorous genetic experiments revealed that Notch signaling forms a positive feedback loop with the Hippo signaling effector YAP/TAZ to promote severe hepatomegaly and rapid HCC initiation and progression.

BMF/MDS may be acquired or inherited, a distinction critical for treatment selection. Currently, diagnosis of these inherited syndromes is based on clinical history, family history, and laboratory studies, which directs the ordering of genetic tests on a gene-by-gene basis. However, despite extensive clinical workup and serial genetic testing, many cases remain unexplained. We sought to define the genetic etiology and pathophysiology of unclassified bone marrow failure and myelodysplastic syndromes. First, to determine the extent to which patients remained undiagnosed due to atypical or cryptic presentations of known inherited BMF/MDS, we developed a massively-parallel, next- generation DNA sequencing assay to simultaneously screen for mutations in 85 BMF/MDS genes. Querying 71 pediatric and adult patients with unclassified BMF/MDS using this assay revealed 8 (11%) patients with constitutional, pathogenic mutations in GATA2 , RUNX1 , DKC1 , or LIG4 . All eight patients lacked classic features or laboratory findings for their syndromes.
