Acylglycerol kinase augments JAK2/STAT3 signaling in esophageal squamous cells
JAK2 activity is tightly controlled through a self-inhibitory effect via its JAK homology domain 2 (JH2), which restricts the strength and duration of JAK2/STAT3 signaling under physiological conditions. Although multiple mutations within JAK2, which abrogate the function of JH2 and sustain JAK2 activation, are widely observed in hematological malignancies, comparable mutations have not been detected in solid tumors. How solid tumor cells override the autoinhibitory effect of the JH2 domain to maintain constitutive activation of JAK2/STAT3 signaling remains puzzling. Herein, we demonstrate that AGK directly interacted with...

Cartilage oligomeric matrix protein enhances osteogenesis by directly binding and activating bone morphogenetic protein-2
Abstract: Bone morphogenetic proteins (BMPs) are effective for bone regeneration, and are used clinically. However, supraphysiological doses are required, which limits their use. Cartilage oligomeric matrix protein is an extracellular matrix protein, which we have previously shown can bind to growth factors of the TGFs family, suggesting that COMP may also bind to BMP-2. Rather than being a passive component of the matrix, COMP may serve as an “instructive matrix” component capable of increasing local growth factor concentration, slowing the diffusion of growth factors, and promoting their biological activity. The purp...

Young blood may help rejuvenate old hearts
Conclusion This study finds that sharing the circulation of young and old mice appears to reverse the age-related thickening of heart muscle cells in the older animal, and it seems this could be due to a certain growth factor in the blood of the young animal. The findings will be of scientific interest, and further our understanding of the processes of heart ageing in animals. However, the findings have very limited direct relevance to humans, and do not suggest a new treatment for heart failure. It is also certainly unknown at this point whether increasing levels of this factor in the blood of people with this type of he...

Development and resolution of secondary autoimmunity after autologous haematopoietic stem cell transplantation for systemic lupus erythematosus: competition of plasma cells for survival niches?
Haematopoietic stem cell transplantation (HSCT) is an effective treatment for severe autoimmune diseases such as systemic lupus erythematosus (SLE).1 However, it is increasingly recognised that these patients have an added propensity to develop secondary autoimmune disorders.2 3 Here, we report on a 21-year-old male patient who received a CD34-selected autologous HSCT following conditioning with antithymocyte-globulin and cyclophosphamide (CYC) after written informed consent for refractory, severe SLE with renal, haematological, mucocutaneous and musculoskeletal manifestations (SLEDAI 19).1 Clinical remission was achieved ...

Stem cell therapy for tendinopathy: lessons from a large animal model
Introduction Tendon disorders compromise pain-free activity and often progress to chronic pain with a major impact on quality of life. Achilles tendinopathy (AT) is particularly common with many proposed therapies. However, apart from eccentric loading exercises, none have been shown to be more effective than placebo.1 Even the recent popular use of platelet-rich plasma has shown poor efficacy.2 3 There is therefore a clear need for new effective non-surgical treatments. Mesenchymal stem cells (MSCs) offer the potential for tendon regeneration and improved functional outcome via either direct or paracrine effects. We have ...

Factors affecting tendinopathogenesis
Discussion We have demonstrated that MSC injections can be effective in reducing surgically-induced tendon pathology and that timing of injection is critically important to the long-term benefit. The in vitro changes in MSC expression suggest that both the tenocytes and the condition of the extracellular environment determine the secretome of the injected cells, and that the MSCs are responding to feedback from their immediate environment. MSCs have potential in the development of a cellular therapy to treat tendinopathy that develops after injury. (Source: British Journal of Sports Medicine)

Effects of mast cells on the function of isolated human tenocytes
Discussion These findings suggest that either through physical association with tenocytes and/or release of mediators, mast cells could play a role in the regulation and activation of tenocytes.

Stem cells, angiogenesis and muscle healing: a potential role in massage therapies?
Skeletal muscle injuries are among the most common and frequently disabling injuries sustained by athletes. Repair of injured skeletal muscle is an area that continues to present a challenge for sports medicine clinicians and researchers due, in part, to complete muscle recovery being compromised by development of fibrosis leading to loss of function and susceptibility to re-injury. Injured skeletal muscle goes through a series of coordinated and interrelated phases of healing including degeneration, inflammation, regeneration and fibrosis. Muscle regeneration initiated shortly after injury can be limited by fibrosis which...

The myelodysplastic syndrome as a prototypical epigenetic disease
The myelodysplastic syndrome (MDS) is a clonal disorder characterized by increased stem cell proliferation coupled with aberrant differentiation resulting in a high rate of apoptosis and eventual symptoms related to bone marrow failure. Cellular differentiation is an epigenetic process that requires specific and highly ordered DNA methylation and histone modification programs. Aberrant differentiation in MDS can often be traced to abnormal DNA methylation (both gains and losses of DNA methylation genome wide and at specific loci) as well as mutations in genes that regulate epigenetic programs (TET2 and DNMT3a, both involve...

GATA2 haploinsufficiency caused by mutations in a conserved intronic element leads to MonoMAC syndrome
Previous reports of GATA2 mutations have focused on the coding region of the gene or full gene deletions. We recently identified 2 patients with novel insertion/deletion mutations predicted to result in mRNA nonsense-mediated decay, suggesting haploinsufficiency as the mechanism of GATA2 deficient disease. We therefore screened patients without identified exonic lesions for mutations within conserved noncoding and intronic regions. We discovered 1 patient with an intronic deletion mutation, 4 patients with point mutations within a conserved intronic element, and 3 patients with reduced or absent transcription from 1 allele...

Identification of the chemokine CCL28 as a growth and survival factor for human hematopoietic stem and progenitor cells
In an attempt to discover novel growth factors for hematopoietic stem and progenitor cells (HSPCs), we have assessed cytokine responses of cord blood (CB)–derived CD34+ cells in a high-content growth factor screen. We identify the immunoregulatory chemokine (C-C motif) ligand 28 (CCL28) as a novel growth factor that directly stimulates proliferation of primitive hematopoietic cells from different ontogenetic origins. CCL28 enhances the functional progenitor cell content of cultured cells by stimulating cell cycling and induces gene expression changes associated with survival. Importantly, addition of CCL28 to culture...

FLT3 activation cooperates with MLL-AF4 fusion protein to abrogate the hematopoietic specification of human ESCs
Mixed-lineage leukemia (MLL)–AF4 fusion arises prenatally in high-risk infant acute pro-B-lymphoblastic leukemia (pro-B-ALL). In human embryonic stem cells (hESCs), MLL-AF4 skewed hematoendothelial specification but was insufficient for transformation, suggesting that additional oncogenic insults seem required for MLL-AF4–mediated transformation. MLL-AF4+ pro-B-ALL expresses enormous levels of FLT3, occasionally because of activating mutations, thus representing a candidate cooperating event in MLL-AF4+ pro-B-ALL. Here, we explored the developmental impact of FLT3 activation alone, or together with MLL-AF4, in ...

A critical role for the retinoic acid signaling pathway in the pathophysiology of gastrointestinal graft-versus-host disease
Damage to the gastrointestinal tract during graft-versus-host disease (GVHD) is one of the major causes of morbidity and mortality in allogeneic hematopoietic stem cell transplant (HSCT) recipients. In the current study, we identified a critical role for the retinoic acid (RA) signaling pathway in the induction and propagation of gastrointestinal GVHD. The administration of exogenous RA significantly increased expression of the gut-homing molecules, CCR9 and α4β7, on donor T cells in mesenteric lymph nodes, and augmented the accumulation of proinflammatory CD4+ and CD8+ T cells within the gut mucosa, leading to ...

Use of V(D)J recombination excision circles to identify T- and B-cell defects and to monitor the treatment in primary and acquired immunodeficiencies
T-cell receptor excision circles (TRECs) and kappa-deleting recombination excision circles (KRECs) are circular DNA segments generated in T and B cells during their maturation in the thymus and bone marrow. These circularized DNA elements persist in the cells, are unable to replicate, and are diluted as a result of cell division, thus are considered markers of new lymphocyte output. The quantification of TRECs and KRECs, which can be reliably performed using singleplex or duplex real-time quantitative PCR, provides novel information in the management of T- and B-cell immunity-related diseases.
