Activation of the thrombopoietin receptor by mutant calreticulin in CALR-mutant myeloproliferative neoplasms.
Recurrent somatic mutations of calreticulin (CALR) have been identified in patients harboring myeloproliferative neoplasms; however, their role in tumorigenesis remains elusive. Here, we found that… Expand

In pluripotent stem cells (PSCs), there are 2 types: naive and primed. Only the naive type has the capacity for producing chimeric offspring. Mouse PSCs are naive, but human PSCs are in the primed… Expand
Homomultimerization of mutant calreticulin is a prerequisite for MPL binding and activation
Studies have previously shown that mutant calreticulin (CALR), found in a subset of patients with myeloproliferative neoplasms (MPNs), interacts with and subsequently promotes the activation of the… Expand
MHC-Matched Induced Pluripotent Stem Cells Can Attenuate Cellular and Humoral Immune Responses but Are Still Susceptible to Innate Immunity in Pigs
Recent studies have revealed negligible immunogenicity of induced pluripotent stem (iPS) cells in syngeneic mice and in autologous monkeys. Therefore, human iPS cells would not elicit immune… Expand
Generating Porcine Chimeras Using Inner Cell Mass Cells and Parthenogenetic Preimplantation Embryos
Background The development and validation of stem cell therapies using induced pluripotent stem (iPS) cells can be optimized through translational research using pigs as large animal models, because… Expand

Somatic mutations in the calreticulin (CALR) gene have been found in most patients with JAK2‐ and MPL‐unmutated Philadelphia chromosome‐negative myeloproliferative neoplasms (MPNs). It has recently… Expand
Mutant calreticulin interacts with MPL in the secretion pathway for activation on the cell surface
Studies have shown that mutant calreticulin (CALR) constitutively activates the thrombopoietin (TPO) receptor MPL and thus plays a causal role in the development of myeloproliferative neoplasms… Expand
Subcellular localization of mutant Clreticulin that induces Myeloproliferative neoplasms(MPNs).
The Zygosity of JAK2V617F Determines the Disease Entities of Myeloproliferative Neoplasms By Modulating Erythropoiesis but Not Megakaryopoiesis
Philadelphia-chromosome negative myeloproliferative neoplasms (MPNs) consists of different clinical entities that include polycythemia vera (PV) and essential thrombocythemia (ET). Despite of… Expand
Localization of Mutant Calreticulin in the Golgi Apparatus Is Required for Its Oncogenic Capacity
Recurrent somatic mutations of the calreticulin (CALR) gene, which encodes a molecular chaperone, have been previously reported in patients with JAK2- and MPL-unmutated essential thrombocythemia and… Expand
