Abstract
BACKGROUND Granulocyte transfusion therapy is a rational therapeutic option for patients with prolonged, severe neutropenia. Although high molecular weight hydroxyethyl starch (hHES) facilitates the separation of red blood cells during granulocyte collection, renal dysfunction has been noted as a potential side effect. HES130/0.4 (Voluven®) is a medium molecular weight HES (mHES) with superior safety profiles compared to hHES. Although HES130/0.4 is reportedly effective in the collection of granulocytes, we lack studies comparing the efficiency of granulocyte collection using HES130/0.4 and hHES. STUDY DESIGN AND METHODS We retrospectively collected the data from 60 consecutive apheresis procedures performed on 40 healthy donors at the Okayama University Hospital between July 2013 and December 2021. All procedures were performed using the Spectra Optia system. Based on the HES130/0.4 concentration in the separation chamber, granulocyte collection methods using HES130/0.4 were classified into m0.46, m0.44, m0.37, and m0.8 groups. We used HES130/0.4 and hHES groups to compare the various sample collection methods. RESULTS The median granulocyte collection efficiency (CE) was approximately 24.0% and 28.1% in the m0.8 and hHES groups, respectively, which were significantly higher than those in the m0.46, m0.44, and m0.37 groups. One month following granulocyte collection with HES130/0.4, no significant changes were observed in serum creatinine levels compared to those before the donation. CONCLUSION Therefore, we propose a granulocyte collection approach employing HES130/0.4, which is comparable to the use of hHES in terms of the granulocyte CE. A high concentration of HES130/0.4 in the separation chamber was considered crucial for granulocyte collection.

Abstract
Posttransplant cyclophosphamide (PTCy) is associated with a low incidence of chronic graft-versus-host disease (cGVHD) following hematopoietic stem cell (HSC) transplantation. Previous studies have shown the important roles of B cell immunity in cGVHD development. Here, we investigated the long-term reconstitution of B lymphopoiesis after PTCy using murine models. We first demonstrated that the immune homeostatic abnormality leading to cGVHD is characterized by an initial increase in effector T cells in the bone marrow and subsequent B and Treg cytopenia. PTCy, but not cyclosporine A or rapamycin, inhibits the initial alloreactive T cell response, which restores intra-bone marrow B lymphogenesis with a concomitant vigorous increase in Tregs. This leads to profound changes in posttransplant B cell homeostasis, including decreased B cell activating factors, increased transitional and regulatory B cells, and decreased germinal center B cells. To identify the cells responsible for PTCy-induced B cell tolerance, we selectively depleted Treg populations that were graft or HSC derived using DEREG mice. Deletion of either Treg population without PTCy resulted in critical B cytopenia. PTCy rescued B lymphopoiesis from graft-derived Treg deletion. In contrast, the negative effect of HSC-derived Treg deletion could not be overcome by PTCy, indicating that HSC-derived Tregs are essential for maintaining favorable B lymphopoiesis following PTCy. These findings define the mechanisms by which PTCy restores homeostasis of the B cell lineage and reestablishes immune tolerance.

Abstract
CD4+Foxp3+ regulatory T cells (Tregs) play a central role in the maintenance of immune tolerance after allogeneic hematopoietic stem cell transplantation (HSCT). Tregs promptly respond to low concentrations of IL-2 through the constitutive expression of high-affinity IL-2 receptors. It has been reported that low-dose IL-2 therapy increased circulating Tregs and improved clinical symptoms of chronic GVHD. Clinical studies of IL-2 therapy so far have mainly targeted patients in the chronic phase of transplantation when acute immune responses has subsided. However, the biological and clinical effects of exogenous IL-2 in an acute immune environment have not been well investigated. In the current study, we investigated the impact of exogenous IL-2 therapy on the post-transplant homeostasis of T cell subsets which influence the balance between GVHD and GVL in the acute phase, by setting the various immune environments early after HSCT in murine model. We initially found that 5,000 IU of IL-2 was enough to induce the active proliferation of Treg without influencing other conventional T cells (Tcons) when administered to normal mice. However, activated Tcons showed the response to the same dose of IL-2 in recipients after allogeneic HSCT. In a mild inflammatory environment within a threshold, exogenous IL-2 could effectively modulate Treg homeostasis with just limited influence to activated T cells, which resulted in an efficient GVHD suppression. In contrast, in a severely inflammatory environment, exogenous IL-2 enhanced activated T cells rather than Tregs, which resulted in the exacerbation of GVHD. Of interest, in an immune-tolerant state after transplant, exogenous IL-2 triggered effector T-cells to exert an anti-tumor effect with maintaining GVHD suppression. These data suggested that the responses of Tregs and effector T cells to exogenous IL-2 differ depending on the immune environment in the host, and the mutual balance of the response to IL-2 between T-cell subsets modulates GVHD and GVL after HSCT. Our findings may provide useful information in the optimization of IL-2 therapy, which may be personalized for each patient having different immune status.

Abstract
BackgroundGenome-wide association studies (GWASs) have identified 29 disease-associated single nucleotide polymorphisms (SNPs) for systemic sclerosis (SSc) in non-human leukocyte antigen (HLA) regions (1-7). While these GWASs have clarified genetic architectures of SSc, study subjects were mainly Caucasians limiting application of the findings to Asians.ObjectivesThe study was conducted to identify novel causal variants for SSc specific to Japanese subjects as well as those shared with European population. We also aimed to clarify mechanistic effects of the variants on pathogenesis of SSc.MethodsA total of 114,108 subjects comprising 1,499 cases and 112,609 controls were enrolled in the two-staged study leading to the ever-largest Asian GWAS for SSc. After applying a strict quality control both for genotype and samples, imputation was conducted using the reference panel of the phase 3v5 1,000 genome project data combined with a high-depth whole-genome sequence data of 3,256 Japanese subjects. We conducted logistic regression analyses and also combined the Japanese GWAS results with those of Europeans (6) by an inverse-variance fixed-effect model. Polygenicity and enrichment of functional annotations were evaluated by linkage disequilibrium score regression (LDSC), Haploreg and IMPACT programs. We also constructed polygenic risk score (PRS) to predict SSc development.ResultsWe identified three (FCRLA-FCGR, TNFAIP3, PLD4) and four (EOMES, ESR1, SLC12A5, TPI1P2) novel loci in Japanese GWAS and a trans-population meta-analysis, respectively. One of Japanese novel risk SNPs, rs6697139, located within FCGR gene clusters had a strong effect size (OR 2.05, P=4.9×10-11). We also found the complete LD variant, rs10917688, was positioned in cis-regulatory element and binding motif for an immunomodulatory transcription factor IRF8 in B cells, another genome-wide significant locus in our trans-ethnic meta-analysis and the previous European GWAS. Notably, the association of risk allele of rs10917688 was significant only in the presence of the risk allele of the IRF8. Intriguingly, rs10917688 was annotated as one enhancer-related histone marks, H3K4me1, in B cells, implying that FCGR gene(s) in B cells may play an important role in the pathogenesis of SSc. Furhtermore, significant heritability enrichment of active histone marks and a transcription factor C-Myc were found in B cells both in European and Japanese populations by LDSC and IMPACT, highlighting a possibility of a shared disease mechanism where abnormal B-cell activation may be one of the key drivers for the disease development. Finally, PRS using effects sizes of European GWAS moderately fit in the development of Japanese SSc (AUC 0.593), paving a path to personalized medicine for SSc.ConclusionOur study identified seven novel susceptibility loci in SSc. Downstream analyses highlighted a novel disease mechanism of SSc where an interactive role of FCGR gene(s) and IRF8 may accelerate the disease development and B cells may play a key role on the pathogenesis of SSc.References[1]F.

Abstract
BACKGROUND CD34+ cell collection efficiency (CE) is the determining factor when calculating processed blood volume (PBV) for leukapheresis (LP). However, the factors affecting CE in the continuous mononuclear cell collection (cMNC) protocol performed by the Spectra Optia apheresis system are not well established. STUDY DESIGN AND METHODS We retrospectively collected the data from 147 consecutive apheresis procedures across 106 healthy donors and 27 patients completed between July 2016 and December 2020 at the Okayama University Hospital. All procedures were performed using the Optia cMNC protocol. RESULTS The median CD34+ CE2 was significantly higher in the donor samples (64.3%) than in the patient samples (46.8%) (p < .0001). WBC counts, hematocrit, and platelet counts were all significantly higher in the donors than in the patients, and there was a moderate positive correlation between CD34+ CE2 and hematocrit (r = .47, p < .0001), with the equation of the line being y = 1.23x + 12.23. In contrast, there was only a very weak correlation between CD34+ CE2 and WBC or platelet count. In addition, low hematocrit correlated with an increased time to interface formation. CONCLUSION These data revealed the negative impact of low hematocrit on the efficiency of CD34+ cell collection when using the Optia cMNC protocol and suggest that hematocrit values should also be considered when determining PBV.

Abstract
Osteogenesis imperfecta (OI) and other decreased bone density disorders comprise a heterogeneous group of heritable diseases with skeletal fragility. Recently, it was discovered that mutations in SGMS2, encoding sphingomyelin synthetase 2, result in aberrant sphingomyelin metabolism and lead to a novel form of OI termed osteoporosis with calvarial doughnut lesions (OP-CDL) with moderate to severe skeletal fragility and variable cranial hyperostotic lesions. This study describes a Japanese family with the skeletal phenotype of OP-CDL. The affected individuals have moderately severe, childhood-onset skeletal fragility with multiple long-bone fractures, scoliosis and bone deformities. In addition, they exhibit multiple CDLs or calvarial bumps with central radiolucency and peripheral radiopacity. However, SGMS2 sequencing was normal. Instead, whole-exome sequencing identified a novel IFITM5 missense mutation c.143A>G (p.N48S) (classified as a VUS by ACMG). IFITM5 encodes an osteoblast-restricted protein BRIL and a recurrent c.-14C>T mutation in its 5' UTR region results in OI type V, a distinctive subtype of OI associated with hyperplastic callus formation and ossification of the interosseous membranes. The patients described here have a phenotype clearly different from OI type V and with hyperostotic cranial lesions, feature previously unreported in association with IFITM5. Our findings expand the genetic spectrum of OP-CDL, indicate diverse phenotypic consequences of pathogenic IFITM5 variants, and imply an important role for BRIL in cranial skeletogenesis.

Abstract
Fludarabine with intravenous busulfan (6.4 mg/kg; FB2) and fludarabine with intermediate-dose melphalan (140 mg/m2; FM140) are the most widely used reduced-intensity conditioning (RIC) regimens for allogeneic hematopoietic stem cell transplantation. FM140 generally has a lower relapse rate and higher non-relapse mortality (NRM), resulting in overall survival (OS) comparable to that seen with FB2. To evaluate the effect of reducing the melphalan dose, we retrospectively compared transplant outcomes in 156 patients who received FB2 (n = 103) or FM80 (n = 53) at our center (median age: 63 years; range 27-72 years). All patients received 4-Gy total body irradiation. Three-year OS, the cumulative incidence of relapse, and NRM were comparable between groups (FB2 vs. FM80, 58% vs. 47%, p = 0.24; 30% vs. 36%, p = 0.57; 17% vs. 21%, p = 0.44, respectively). There was no significant difference in the cumulative incidence of graft-versus-host disease (GVHD) at day 100, chronic GVHD at 3 years, or the 3-year GVHD-free/relapse-free survival rate. In the high-risk disease group, patients receiving FM80 tended to have lower 3-year OS (FB2 vs. FM80, 48% vs. 17%, p = 0.06). In summary, transplant outcomes following FB2 or FM80 were comparable except in patients with high-risk disease.

Abstract
CD4+CD25+Foxp3+ regulatory T cells (Tregs) are functionally distinct subsets of mature T cells with broad suppressive activity and have been shown to play an important role in the establishment of immune tolerance after allogeneic hematopoietic stem cell transplantation (HSCT). Tregs exhibit an activated phenotype from the stage of emigration from the thymus and maintain continuous proliferation in the periphery. The distinctive feature in homeostasis enables Tregs to respond sensitively to small environmental changes and exert necessary and sufficient immune suppression; however, on the other hand, it also predisposes Tregs to be susceptible to apoptosis in the inflammatory condition post-transplant. Our studies have attempted to define the intrinsic and extrinsic factors affecting Treg homeostasis from the acute to chronic phases after allogeneic HSCT. We have found that altered cytokine environment in the prolonged post-HSCT lymphopenia or peri-transplant use of immune checkpoint inhibitors could hamper Treg reconstitution, leading to refractory graft-versus-host disease. Using murine models and clinical trials, we have also demonstrated that proper intervention with low-dose interleukin-2 or post-transplant cyclophosphamide could restore Treg homeostasis and further amplify the suppressive function after HSCT. The purpose of this review is to reconsider the distinctive characteristics of post-transplant Treg homeostasis and discuss how to harness Treg homeostasis to optimize posttransplant immunity for developing a safe and efficient therapeutic strategy.

Abstract
OBJECTIVE Osteoarthritis (OA) is the most prevalent age-related disorder due to cartilage degradation. Previous studies have identified aberrant chondrocyte homeostasis under extracellular stress as a key pathological mechanism behind cartilage degradation in OA. TDP-43, a DNA/RNA-binding protein has been demonstrated to participate in processing many extracellular stress responses; however, understanding of the role of TDP-43 in OA is limited. This study aims to investigate the role of TDP-43 in chondrocyte homeostasis and cartilage degradation in OA. METHODS The role of TDP-43 during degradation of cartilage is examined by experimental posttraumatic OA animal models and human cartilage specimens. Cartilage degradation is assessed by histological analysis, qPCR, and Western blot. The molecular mechanisms are investigated in vitro using human primary chondrocytes. RESULTS TDP-43 decreases significantly in degenerated cartilage. TDP-43 concentration is positively correlated with IL-1β concentration in synovial fluid derived from OA patients (Pearson r = 0.95, CI (95%) [0.80, 0.99], P < 0.0001). Intra-articular injection of recombinant TDP-43 significantly alleviates cartilage degradation and subchondral bone remodeling in vivo. In vitro mechanistic analyses show that TDP-43 maintains chondrocyte homeostasis under oxidative stress through regulating stress granule dynamics via G3BP1. CONCLUSION The present study indicates that TDP-43 maintains chondrocyte homeostasis under oxidative stress and alleviates cartilage degeneration in osteoarthritis, identifying TDP-43 as a potential target for the diagnosis and treatment of knee OA.

Abstract
Posttransplantation cyclophosphamide (PTCy) has become a popular option for haploidentical hematopoietic stem cell transplantation (HSCT). However, personalized methods to adjust immune intensity after PTCy for each patient’s condition have not been well studied. Here, we investigated the effects of reducing the dose of PTCy followed by α-galactosylceramide (α-GC), a ligand of iNKT cells, on the reciprocal balance between graft-versus-host disease (GVHD) and the graft-versus-leukemia (GVL) effect. In a murine haploidentical HSCT model, insufficient GVHD prevention after reduced-dose PTCy was efficiently compensated for by multiple administrations of α-GC. The ligand treatment maintained the enhanced GVL effect after reduced-dose PTCy. Phenotypic analyses revealed that donor-derived B cells presented the ligand and induced preferential skewing to the NKT2 phenotype rather than the NKT1 phenotype, which was followed by the early recovery of all T cell subsets, especially CD4+Foxp3+ regulatory T cells. These studies indicate that α-GC administration soon after reduced-dose PTCy restores GVHD-preventing activity and maintains the GVL effect, which is enhanced by reducing the dose of PTCy. Our results provide important information for the development of a novel strategy to optimize PTCy-based transplantation, particularly in patients with a potential relapse risk.

Abstract
Graft-versus-host disease (GVHD) remains to be a significant cause of morbidity and mortality after allogeneic hematopoietic stem cell transplantation (HSCT). IL-2-inducible T cell kinase (ITK), a TEC cytoplasmic tyrosine kinase, has an essential role in T cell development and receptor signaling. The ITK/Bruton tyrosine kinase inhibitor ibrutinib has been shown to improve chronic GVHD symptoms; however, the effect of ITK selective inhibition on acute GVHD remains unclear. In this study, we evaluated the pharmacological effects of an ITK selective inhibitor (ITKsi) on acute GVHD using murine bone marrow transplantation models. First, we found that CD4+ T cell differentiation toward Th1, Th2, or Th17 was inhibited following ITKsi treatment in a dose-dependent manner while maintaining regulatory T cells in the presence of alloantigens both in vitro and in vivo. ITKsi preferentially inhibited inflammatory cytokine production and in vivo proliferation of alloreactive T cells. We then demonstrated that short-term exposure of donor graft cells to ITKsi significantly delayed the onset of GVHD-associated mortality without compromising the donor cell engraftment and the graft-versus-tumor effect, indicating the potential of ITK selective inhibition in the setting of clinical allogeneic HSCT. These findings suggest that ITK is a potential therapeutic target against GVHD, and the pharmacological ITK inhibitor may serve as a novel strategy for immune regulation after HSCT.

Abstract
Background and Aim Chronic graft‐versus‐host disease (cGVHD) is a major cause of nonrelapse morbidity and mortality following hematopoietic stem cell transplantation (HSCT). α‐Galactosylceramide (α‐GC) is a synthetic glycolipid that is recognized by the invariant T‐cell receptor of invariant natural killer T (iNKT) cells in a CD1d‐restricted manner. Stimulation of iNKT cells by α‐GC leads to the production of not only immune‐stimulatory cytokines but also immune‐regulatory cytokines followed by regulatory T‐cell (Treg) expansion in vivo. Methods We investigated the effect of iNKT stimulation by liposomal α‐GC just after transplant on the subsequent immune reconstitution and the development of sclerodermatous cGVHD. Results Our study showed that multiple administrations of liposomal α‐GC modulated both host‐ and donor‐derived iNKT cell homeostasis and induced an early expansion of donor Tregs. We also demonstrated that the immune modulation of the acute phase was followed by the decreased levels of CXCL13 in plasma and follicular helper T cells in lymph nodes, which inhibited germinal center formation, resulting in the efficient prevention of sclerodermatous cGVHD. Conclusions These data demonstrated an important coordination of T‐ and B‐cell immunity in the pathogenesis of cGVHD and may provide a novel clinical strategy for the induction of immune tolerance after allogeneic HSCT.

Abstract
Peripheral blood progenitor cells (PBPCs) are a predominant graft source in allogeneic hematopoietic cell transplantation. Citrate-induced hypocalcemia remains the most frequent side effect of PBPC apheresis. Although the method for preventing severe adverse events is established, more efficient prophylaxis is required so that volunteer donors can donate PBPCs without pain and anxiety. We studied 80 healthy donors who underwent PBPC harvest between February 2014 and June 2020. Of these, 23 donors who underwent apheresis between February 2014 and December 2015 received only the standard prophylaxis of intravenous calcium gluconate. Oral calcium drinks were provided to 57 donors who underwent apheresis from January 2016 to June 2020 to supplement intravenous calcium gluconate prophylaxis. The ionized calcium (ICa) levels at multiple time intervals and the hypocalcemic symptoms were evaluated. Oral supplementation with a calcium drink maintained significantly higher ICa levels. Analysis using the inverse probability weighted regression adjustment method suggested that calcium drinks reduced the frequency of citrate-related reactions by 39.2 %. Administering a prophylactic oral calcium drink before apheresis with intravenous administration of calcium gluconate is promising to further reduce citrate-induced hypocalcemia in volunteer donors.

Abstract
Photodynamic therapy (PDT) is an emerging treatment for various solid cancers. We recently reported that tumor cell lines and patient specimens from adult T cell leukemia/lymphoma (ATL) are susceptible to specific cell death by visible light exposure after a short-term culture with 5-aminolevulinic acid, indicating that extracorporeal photopheresis could eradicate hematological tumor cells circulating in peripheral blood. As a bridge from basic research to clinical trial of PDT for hematological malignancies, we here examined the efficacy of ALA-PDT on various lymphoid malignancies with circulating tumor cells in peripheral blood. We also examined the effects of ALA-PDT on tumor cells before and after conventional chemotherapy. With 16 primary blood samples from 13 patients, we demonstrated that PDT efficiently killed tumor cells without influencing normal lymphocytes in aggressive diseases such as acute ATL. Importantly, PDT could eradicate acute ATL cells remaining after standard chemotherapy or anti-CCR4 antibody, suggesting that PDT could work together with other conventional therapies in a complementary manner. The responses of PDT on indolent tumor cells were various but were clearly depending on accumulation of protoporphyrin IX, which indicates the possibility of biomarker-guided application of PDT. These findings provide important information for developing novel therapeutic strategy for hematological malignancies.

Abstract
OBJECTIVE To clarify the genetic mechanisms underlying intervertebral disc degeneration (IDD), we examined the associations between single-nucleotide polymorphisms (SNPs) and indicated as coefficient of interaction term (IDD) in a general population in Japan. METHODS This was a cross-sectional study. In 1,605 participants, C2-3 to L5/S1 in the total spine magnetic resonance imaging (MRI) were evaluated using the Pfirrmann's scoring system. Disc scores of 4 and 5 were defined as IDD. Eight SNPs in eight genes associated with IDD were examined at each disc level, considering the non-genetic risk factors of age, sex, and body mass index (BMI). RESULTS The highest odds ratio was found for rs9406328 in the THBS2 gene at disc level T12-L1 (OR 1.27, 95%CI 1.05 to 1.53), and this association was strengthened after adjustment for age using logistic regression (OR 1.37, 95%CI 1.12 to 1.67). Among participants aged <50 years and 50-59, the average IDD score in those with 2 risk alleles of rs9406328 was markedly higher than in those with 0 or 1 risk allele, and the difference is much wider than the elderly participants. It indicates the genetic effect of rs9406328 is stronger in the younger age groups. Finally, multiple linear regression analyses of the association between rs9406328 and IDD, adjusted for age, sex, and BMI at each disc level, showed a statistical interaction between age and the number of risk alleles at C7-T1, T3-4 and T4-T5 as well as T12-L1. CONCLUSION CONCLUSION: The association between rs9406328 in THBS2 and IDD was replicated. The contributions of genetic and environmental factors to IDD differed by disc level.

Abstract
A 51-year-old man underwent allogeneic bone marrow transplantation (BMT) for recurrent acute myeloid leukemia. Although the patient developed slight edema, pleural effusion, and cardiac effusion 6 months after BMT, his clinical condition improved with furosemide treatment. The patient was transfused with red blood cells for the management of anemia 8 months after BMT. He developed acute respiratory failure with pulmonary alveolar hemorrhage 80 min after the transfusion. He was diagnosed with transfusion-associated circulatory overload (TACO) due to the presence of acute pulmonary congestion and depressed left ventricular systolic function. Reduced circulatory load due to sufficient furosemide led to ventilator weaning 3 days later. Other causes of pulmonary alveolar hemorrhage were excluded, and the patient's condition improved by cardiac failure treatment only. This clinical course indicated that pulmonary alveolar hemorrhage would breakdown the blood vessels due to acute pulmonary congestion. Chemotherapy and prolonged anemia are high risks for cardiac failure in patients with hematological malignancies. Therefore, the possibility of cardiac failure is considered when patients with hematological malignancies have fluid retention, such as cardiac enlargement, edema, and pleural effusion. Moreover, the body fluids should be monitored before and after blood transfusion.

Abstract
Mogamulizumab (Mog), a humanized anti-CCR4 antibody, provides an important treatment option for relapsed/refractory adult T cell leukemia/lymphoma. However, administration of Mog before allogenic hematopoietic stem cell transplantation has been reported to be a risk factor for severe acute graft-versus-host disease (GVHD). The etiological hypothesis is Mogamulizumab may eradicate CCR4-positive regulatory T cells (Tregs). Theoretically, Treg homeostasis and course of GVHD can be affected by plasma exchange (PE) with decreasing plasma Mog concentration. Here, we present a case of severe acute GVHD after pretransplantation Mog, in which PE was performed for liver failure. As a result, plasma Mog concentration was decreased but it did not lead to the prompt elevation of Treg levels in peripheral blood and clinical responses of GVHD were limited to partial remission. Our case suggests that recovery of donor-derived Treg in the acute phase after HSCT is multifactorial and the single procedure of PE-based Mog depletion does not necessarily warrant the quick restoration of Treg homeostasis.

Abstract
Neurolymphomatosis is a rare form of extranodal malignant lymphoma defined as the infiltration of malignant lymphocytes into the central or peripheral nerve. We herein report a case of neurolymphomatosis in the cauda equina diagnosed by an open surgical biopsy. He presented with muscle weakness, atrophy, numbness and hypoesthesia in the bilateral lower extremities with the accumulation of 18fluoro-2-deoxyglucose (FDG) in the bilateral cauda equina. Cerebrospinal fluid cytology (three times) and flow cytometry (two times) and biopsies of the left sural nerve, bone marrow, paranasal sinus and left testis were all negative for malignancy, so finally we performed a surgical open biopsy of the cauda equina by laminectomy and diagnosed him with diffuse large B-cell lymphoma in the cauda equina. He was successfully treated with the disappearance of the FDG accumulation for a long time. The present case suggested that an early open biopsy of the cauda equina may be considered for cases of suspected neurolymphomatosis in the cauda equina for a good outcome.

Abstract
Cytomegalovirus meningitis/meningoencephalitis is a potentially fatal complication following hematopoietic stem cell transplantation that causes significant morbidity and mortality. In the pre-transplant setting, a few cases involving lymphoid malignancies have been reported. However, there have been no reports of patients with myeloid malignancies. A 36-year-old man with relapsed acute myeloid leukemia received high-dose cytarabine-containing salvage chemotherapies and then developed grade 4 lymphopenia for more than one month. Subsequently, the patient developed pyrexia, accompanying headache, nausea, and vomiting with no abnormal brain imaging. Despite receiving antimicrobial treatment, his febrile status and headache persisted. Given that the patient had symptoms consistent with viral meningitis with no evidence of etiology other than positive cytomegalovirus-DNA in his cerebrospinal fluid and cytomegalovirus pp65 antigenemia, cytomegalovirus meningitis was diagnosed. After commencing ganciclovir treatment, the patient's headache and febrile status rapidly improved. Cytomegalovirus meningitis/meningoencephalitis is rare before hematopoietic stem cell transplantation, but may be useful in differential diagnoses in heavily treated acute myeloid leukemia patients with central nervous system symptoms.

Abstract
The number of patients who are successfully discharged from the intensive care unit (ICU) after hematopoietic stem cell transplantation (HSCT) remains limited. Most previous studies have evaluated short-term outcomes using ICU mortality; there have been comparatively fewer reports of long-term outcomes. We retrospectively analyzed 39 HSCT patients admitted to the ICU for the first time between April 2008 and July 2014. Performance status was evaluated in four long-term survivors in July 2016. Median age at ICU admission was 54 years (range 30-68). In total, 33 patients (70.2%) required mechanical ventilation and 31 patients (66%) required dialysis. The median OS from first ICU admission was 41 days (95% confidence interval [CI]: 22-64) and the 1-year survival rate was 12.8% (95% CI 4.7-25.2). No statistically significant factors were associated with short-term outcomes. Among long-term outcomes, a second or subsequent HSCT and neutropenia at ICU admission were significant risk factors. Four of 10 ICU survivors have survived with good performance status for a median of 1994 (1203-2633) days. Our results suggest that the number of prior transplants and neutropenia at ICU admission may influence OS.

Abstract
A 52-year-old man suffered from progressive multifocal leukoencephalopathy (PML) after human leukocyte antigen (HLA)-haploidentical transplantation with post-transplantation cyclophosphamide (PTCY). Mirtazapine, mefloquine, and cytarabine failed to improve his symptoms, and he finally died 4.5 months after PML onset. This is the first case report of a patient with PML after HLA-haploidentical transplantation with PTCY. Although T-cell replete HLA-haploidentical transplantation with PTCY has enabled early immune reconstitution, PML should be considered if a patient's mental condition deteriorates.

Abstract
Congenital scoliosis (CS) is a common vertebral malformation with incidence of up to 1 of 1000 births worldwide. Recently, TBX6 has been reported as the first disease gene for CS: about 10% of CS patients are compound heterozygotes of rare null mutations and a common haplotype composed by 3 SNPs in TBX6. Lefebvre et al in this journal reported that 2 patients with spondylocostal dysostosis (SCD), a rare skeletal dysplasia affecting spine and ribs also have TBX6 mutations: 1 carried the microdeletion and a rare missense variant, and another 2 rare missense variants. We investigated the pathogenicity of the 3 missense variants in SCD by a luciferase assay. The results were negative for the proposal of Lefebvre et al. We consider these 2 SCD patients are more probably compound heterozygotes of null mutations and a common risk haplotype just as CS patients with TBX6 mutations.

Abstract
We describe herein the clinical outcomes of 16 patients with chronic myeloid leukemia in the chronic phase who stopped the administration of tyrosine kinase inhibitors (TKI) after maintaining undetectable levels of major BCR-ABL1, based on real-time quantitative polymerase chain reaction, for prolonged periods (undetectable MR for a median of 2,100 days (822-4,068). The reasons for discontinuing TKI were enrollments in a clinical trial testing discontinuation of these agents (n=9), adverse effects (n=2) or financial problems (n=5). After TKI discontinuation, patients were followed for a median of 551 days (154-2,446). A total of 8 patients (50%) experienced molecular relapse after a median of 119 days (28-171). Among them, 6 patients who lost major molecular response (MMR) were treated with imatinib (n=2) or dasatinib (n=4), while 2 patients who lost undetectable MR after discontinuing TKI (1 each had taken bostinib and imatinib) but maintained MMR were carefully monitored without re-administration of TKI. Of 6 patients who re-started TKI, 4 (67%) achieved undetectable MR but the other 2 achieved only MMR. The results of this small, retrospective study may support the current understanding of treatment discontinuation, possibly leading to a sustained deep molecular response in some patients.

Abstract
A 60-year-old man with myelodysplastic syndrome underwent allogeneic transplantation of female umbilical cord blood in 2010 and sustained a complete remission. He experienced severe pain in his left hip joint and was admitted to the orthopedic surgery division of our institution in February 2015. After admission, he was suspected to have hemophagocytic syndrome (HPS) and was thus transferred to the hematology division. Bone marrow aspiration revealed hyper-cellular marrow filled with abnormal collapsed cells, consistent with bone marrow necrosis (BMN). As there was no evidence of infection, collagen disease, or occult cancer, he was diagnosed with HPS of unknown origin and treated with dexamethasone, cyclosporine A, and etoposide according to the HLH-2004 protocol. Although his general condition and laboratory findings showed amelioration, morphologically abnormal cells appeared in peripheral blood two weeks after treatment. Bone marrow aspiration showed BMN with increased abnormal cells, positive for CD117 and MPO. Sex chromosome FISH analysis revealed donor chimerism and cytogenetic analysis showed 46XX, +1, der (1;7) (q10;q10). He was diagnosed with donor cell leukemia (DCL) and received salvage chemotherapy. However, he died because of severe pneumonia and sepsis without neutrophil recovery at day 68. We herein report this rare case of DCL with BMN.

Abstract
A 58-year-old female was diagnosed with Philadelphia chromosome positive chronic myeloid leukemia (CML) in blast crisis (BC) in 2004. The patient received imatinib, which quickly induced molecular remission, and subsequently underwent bone marrow transplantation (BMT) from an unrelated human leukocyte antigen (HLA)-identical donor. The post-transplant clinical course was essentially uneventful. In 2014, ten years after the BMT, the patient was admitted to our hospital complaining of lymphadenopathy, and blasts were observed in peripheral blood. The patient was diagnosed as having a CML relapse in myeloid BC, with leukemic infiltration in lymph nodes, and was treated with dasatinib. Subsequently, pleural effusion developed and nilotinib was administered, which induced normal blood counts without blasts and partial cytogenetic remission, one month after administration. Six months after the relapse, this patient underwent a second BMT from an HLA-matched unrelated donor. Recent studies have demonstrated the cumulative incidence of CML relapse more than five years after allogeneic hematopoietic stem cell transplantation (allo-HSCT) to be higher than in acute myeloid leukemia. Although rare, the possibility of late relapse should be considered in patients diagnosed with CML after allo-HSCT.

Abstract
Recent studies have shown that acute myeloid leukemia with myelodysplasia-related changes (AML-MRC) exhibits a worse clinical outcome than AML not otherwise specified (AML-NOS). However, transplant outcomes of patients with AML-MRC have not been reported compared to patients with AML-NOS. We analyzed transplant outcomes among 147 patients with AML-MRC or AML-NOS who underwent allogeneic hematopoietic stem cell transplant (allo-HSCT) in a single institution. There were no significant differences in the 2-year overall survival (OS), cumulative incidence of relapse (CIR), and non-relapse mortality (NRM) between the two groups (2-year OS: 48% vs. 59%; 2-year CIR: 37% vs. 35%; 2-year NRM: 19% vs. 13%). Subgroup analysis adjusting for age and disease status demonstrated the same results between the two groups. Furthermore, multivariate analysis showed that AML-MRC was not an independent prognostic factor for poor prognosis in the setting of allo-HSCT (p = 0.7). These results suggest that allo-HSCT may overcome the poor prognosis of AML-MRC.

Abstract
A 53-year-old woman was admitted with right upper-extremity pain and multiple subcutaneous masses. Bone marrow aspirate showed hypercellular marrow with increased myeloid components at all stages of maturation. Cytogenetic analysis of the bone marrow revealed 100% Philadelphia chromosome positivity along with BCR/ABL gene rearrangement, as demonstrated by polymerase chain reaction (PCR). A diagnosis of chronic phase of chronic myeloid leukemia (CML) was therefore made. Biopsy of one of the subcutaneous masses showed proliferation of granulocytes in various stages of differentiation. There were also erythroid cells and megakaryocytes, without p53 and CD34-positive blasts. These results suggested that the subcutaneous masses had developed from extramedullary hematopoiesis, not blastomas. The patient was administered dasatinib (DA) 140 mg, combined with radiation therapy for pain and peripheral neuropathy from the right axial extramedullary tumor. The patient showed complete hematological remission and the subcutaneous masses had disappeared 1 month after starting administration of DA. Because the patient did not achieve a cytogenetic response, the tyrosine kinase inhibitor nilotinib was administered. She will undergo allogeneic stem cell transplantation in the near future. Extramedullary hematopoiesis in the early stages of CML is uncommon. Our case emphasizes the need to elucidate the pathogenesis of extramedullary hematopoiesis in the early stages of CML.

Abstract
OBJECTIVE The aim of this work was to characterize the genome-wide DNA methylation profile of cartilage from three regions of tibial plateau isolated from patients with primary knee osteoarthritis (OA), providing the first DNA methylation study that reflects OA progression. METHODS The unique model system was used to section three regions of tibial plateau: the outer lateral tibial plateau (oLT), the inner lateral tibial plateau (iLT) and the inner medial tibial plateau (iMT) regions which represented the early, intermediate and late stages of OA, respectively. Genome-wide DNA methylation profile was examined using Illumina Infinium HumanMethylation450 BeadChip array. Comparisons of the iLT/oLT and iMT/oLT groups were carried out to identify differentially methylated (DM) probes (DMPs) associated with OA progression. DM genes were analyzed to identify the gene ontologies (GO), pathways, upstream regulators and networks. RESULTS No significant DMPs were identified in iLT/oLT group, while 519 DMPs were identified in iMT/oLT group. Over half of them (68.2%) were hypo-methylated and enriched in enhancers and OpenSea. Upstream regulator analysis identified many microRNAs. DM genes were enriched in transcription factors, especially homeobox genes and in Wnt/β-catenin signaling pathway. These genes also showed changes in expression when analyzed with expression profiles generated from previous studies. CONCLUSION Our data suggested the changes in DNA methylation occurred at the late stage of OA. Pathways and networks enriched in identified DM genes highlighted potential etiologic mechanism and implicated the potential cartilage regeneration in the late stage of knee OA.

Abstract
A high-flow nasal cannula (HFNC) is a newly developed device that enables high-flow oxygen therapy for patients with serious cardiopulmonary problems, but there are few data regarding its use in patients with hematological disease. The efficacy and tolerability of HFNCs for patients who developed ARF during the treatment of various hematological diseases was evaluated. Fifty-six patients underwent HFNC therapy during the last 2 years, and the causes of ARF were mainly pneumonia (n = 37) or acute congestive heart failure (n = 7). Only 11 patients (20 %) showed a good response to HFNC therapy, and remaining 45 patients (80 %) failed to respond to the initial HFNC therapy and, therefore, underwent second-line therapy including endotracheal intubation with mechanical ventilation (n = 15), non-invasive positive pressure ventilation (n = 1), or narcotic palliation alone (n = 29). Thus, HFNC appear not to be a viable treatment option in 4 out of 5 patients in this cohort of patients with hematological disease, but it was well tolerated in most patients (96 %); no major complications except for nasal soreness (n = 2) were observed. Multivariate analysis showed that the cause of ARF (pneumonia, odds ratio 11.2, 95 % CI 1.76–71.5, p = 0.01) was the only risk factor for treatment failure.

Abstract
Recent studies have shown that CD25 expression at the time of diagnosis of acute myeloid leukemia (AML) may be associated with an unfavorable outcome. We focus on patients with AML without complete remission (CR) and examine the clinical correlation between surface CD25 expression at the time of transplant and subsequent transplant outcomes. We observed a significant difference in overall survival (OS), disease-free survival (DFS) and cumulative incidence of relapse (CIR) between CD25 positive (+) (n = 22) and negative (-) groups (n = 44) (2-year OS; CD25 (+) group: 5% vs. CD25 (-) group: 40%, p < 0.0001, 2-year DFS; 5% vs. 29%, p < 0.0001, 2-year CIR; 77% vs. 52%, p = 0.03). Multivariate analysis showed that CD25 expression was an independent adverse factor for OS (p = 0.002) and relapse (p = 0.001). Patients with AML with residual CD25 positive blasts at the time of transplant may require additional therapy before or after transplant to improve survival.

Abstract
To clarify the clinical impact of prior use of azacitidine (AZA) on outcomes of allogeneic hematopoietic stem cell transplantation (allo-HSCT) for myelodysplastic syndrome (MDS), we retrospectively reviewed the clinical outcomes of 15 MDS patients who were treated with AZA before allo-HSCT (AZA group). We compared the outcomes of these 15 patients with 52 MDS patients who were solely given the best supportive care (BSC) before allo-HSCT (BSC group). Although patients in the AZA group were older with higher International Prognostic Scoring System (IPSS) scores compared to patients in the BSC group, no significant differences were found between the two groups in overall survival (OS), disease-free survival (DFS), cumulative incidence of relapse (CIR) or non-relapse mortality. However, in patients with a higher IPSS score (Int-2/High), pre-transplant AZA may provide better OS and DFS and lower CIR. Acute graft-versus-host disease rates were similar between the two groups. These results should be reassuring to patients with high-risk MDS receiving AZA before allo-HSCT.

Abstract
Spondylometaphyseal dysplasia Algerian type (SMD-A) is an autosomal dominant disorder that was first reported in an Algerian family by Kozlowski et al. [Pediatr Radiol 1988;18:221-226]. Kozlowski's group reported a sporadic case in a 12-year-old Polish boy. They proposed SMD-A as a distinctive skeletal dysplasia and also suggested that a case of SMD reported by Schmidt et al. [J Pediatr 1963;63:106-112] might have had the same disorder. Afterwards, however, no additional report has emerged to date. In addition, the question whether SMD-A belongs to type II collagenopathy (a group of disorders due to a heterozygous mutation of COL2A1) has been continuously under debate. Here we report a 7-year-old Japanese boy with a heterozygous missense mutation in COL2A1, 2582G>T (Gly861Val), whose phenotype matched that of SMD-A. Our observation supports the hypothesis that SMD-A is a variant of type II collagenopathy.

Abstract
Muscle stretching transiently decreases muscle-blood flow corresponding to a muscle extension. It may disturb a balance between muscular oxygen demand and oxygen supply to muscles and reduce muscle oxygenation. However, muscle-stretching training may improve blood circulatory condition, resulting in the maintained muscle oxygenation during muscle stretching. The aim of this study was to investigate changes in muscle-blood volume (tHb) and tissue oxygenation index (TOI) during muscle stretching determined by using near-infrared spectroscopy (NIRS) in ballet-trained (BT) and untrained (C) subjects. 11 BT women who regularly perform muscle stretching and 11 C women participated in this study. Fascicle lengths, tHb and TOI in the tibialis anterior muscle were measured during passive plantar flexion from ankle joint angles of 120° (baseline) to 140°, 160°, the maximal comfortable position without pain (CP), and the maximal position (MP). At 160°, the % fascicle-length change from baseline was significantly lower in the BT than the C group, however, for the changes in tHb and TOI the significant interaction effect between the 2 groups was not detected. On the other hand, although the increases in the fascicle length from baseline to CP and MP were greater in BT than C, the tHb and TOI reductions were comparable between groups. We concluded that it appears that BT can extend their muscles without excessive reduction in muscle-blood volume and muscle oxygenation at relatively same but absolutely greater muscle-stretching levels than C. The attenuation in these indices during high-level muscle stretching may be associated with the repetitive muscle stretching of long-term ballet training.

Abstract
A 37-year-old Japanese man was diagnosed with liver cirrhosis due to Wilson's disease in 2001 and treated with D-penicillamine. Thereafter, he was admitted to our hospital for further examination of a space occupying lesion in the liver. The patient was diagnosed with hepatocellular carcinoma (HCC) (7th segment, 2.5 cm in diameter) in May 2010 and treated with radiofrequency ablation therapy. Biopsy findings from a non-cancerous area revealed a fatty liver, though cirrhotic nodules were not found. Long-term treatment for Wilson's disease may improve hepatic fibrosis, and careful screening for HCC by abdominal imaging is needed in such cases.

Abstract
BACKGROUND Mutations in TRPV4, a gene that encodes a Ca(2+) permeable non-selective cation channel, have recently been found in a spectrum of skeletal dysplasias that includes brachyolmia, spondylometaphyseal dysplasia, Kozlowski type (SMDK) and metatropic dysplasia (MD). Only a total of seven missense mutations were detected, however. The full spectrum of TRPV4 mutations and their phenotypes remained unclear. OBJECTIVES AND METHODS To examine TRPV4 mutation spectrum and phenotype-genotype association, we searched for TRPV4 mutations by PCR-direct sequencing from genomic DNA in 22 MD and 20 SMDK probands. RESULTS TRPV4 mutations were found in all but one MD subject. In total, 19 different heterozygous mutations were identified in 41 subjects; two were recurrent and 17 were novel. In MD, a recurrent P799L mutation was identified in nine subjects, as well as 10 novel mutations including F471del, the first deletion mutation of TRPV4. In SMDK, a recurrent R594H mutation was identified in 12 subjects and seven novel mutations. An association between the position of mutations and the disease phenotype was also observed. Thus, P799 in exon 15 is a hot codon for MD mutations, as four different amino acid substitutions have been observed at this codon; while R594 in exon 11 is a hotspot for SMDK mutations. CONCLUSION The TRPV4 mutation spectrum in MD and SMDK, which showed genotype-phenotype correlation and potential functional significance of mutations that are non-randomly distributed over the gene, was presented in this study. The results would help diagnostic laboratories establish efficient screening strategies for genetic diagnosis of the TRPV4 dysplasia family diseases.

Abstract
BACKGROUND Schneckenbecken dysplasia (SBD) is an autosomal recessive lethal skeletal dysplasia that is classified into the severe spondylodysplastic dysplasias (SSDD) group in the international nosology for skeletal dysplasias. The radiological hallmark of SBD is the snail-like configuration of the hypoplastic iliac bone. SLC35D1 (solute carrier-35D1) is a nucleotide-sugar transporter involved in proteoglycan synthesis. Recently, based on human and mouse genetic studies, we showed that loss-of-function mutations of the SLC35D1 gene (SLC35D1) cause SBD. OBJECT To explore further the range of SLC35D1 mutations in SBD and elucidate whether SLC35D1 mutations cause other skeletal dysplasias that belong to the SSDD group. METHODS AND RESULTS We searched for SLC35D1 mutations in five families with SBD and 15 patients with other SSDD group diseases, including achodrogenesis type 1A, spondylometaphyseal dysplasia Sedaghatian type and fibrochondrogenesis. We identified four novel mutations, c.319C>T (p.R107X), IVS4+3A>G, a 4959-bp deletion causing the removal of exon 7 (p.R178fsX15), and c.193A>C (p. T65P), in three SBD families. Exon trapping assay showed IVS4+3A>G caused skipping of exon 4 and a frameshift (p.L109fsX18). Yeast complementation assay showed the T65P mutant protein lost the transporter activity of nucleotide sugars. Therefore, all these mutations result in loss of function. No SLC35D1 mutations were identified in all patients with other SSDD group diseases. CONCLUSION Our findings suggest that SLC35D1 loss-of-function mutations result consistently in SBD and are exclusive to SBD.

Abstract
OBJECTIVES To replicate a previously reported association with osteoarthritis (OA) of the promoter single nucleotide polymorphism (SNP) rs10980705 in the endothelial differentiation gene 2 (EDG2). METHODS Five collections of samples, four from Europe and one from China, were studied. They included patients with 3 OA phenotypes: 1501 with knee OA, 1497 with hip OA and 376 with generalised OA. A total of 2521 controls were also studied. Allele and genotype frequencies of the rs10980705 SNP were analysed in each individual sample collection and in pooled data. In addition, a meta-analysis to incorporate results from the original Japanese report was performed. RESULTS The association of the rs10980705 SNP with knee OA was not replicated in any of the five sample collections studied or in their combined analysis (odds ratio (OR) 1.10, 95% CI 0.98 to 1.22; p = 0.10). Meta-analysis of all data, including the original Japanese study, did show association with knee OA (OR 1.15, 95% CI 1.06 to 1.26; p = 0.002) but the effect was accounted for by the Japanese data and was less significant than the original report. No association was found with hip OA or with generalised OA. CONCLUSIONS The original report of a promising genetic association between a druggable G-protein coupled receptor, EDG2, and knee OA has not been replicated. This lack of replication could be due to a modest effect of the promoter polymorphism that will require even larger studies (the winners curse) although a more pronounced effect in the Asian population vs Europeans cannot be excluded.

Abstract
AIM This study investigated the force-velocity characteristics of the vastus lateralis (VL) muscle fascicle and muscle-tendon unit (MTU) in isolated lengthening and shortening actions, and during natural movement. METHODS Four subjects performed maximal eccentric and concentric knee extensions (60, 120 and 180 degrees s-1). Unilateral counter movement jumps and drop jumps in the sledge apparatus served as natural movements. Vastus lateralis fascicle lengths were determined from ultrasonography. In vivo patellar tendon forces (PTF) were measured with an optic fibre technique. Patellar tendon force was derived to VL force according to the cross-sectional area of the muscle. Force in the direction of fascicle was calculated by dividing the VL force value by cosine of the fascicle angle. Force-velocity curves were constructed using angle specific values from isokinetic knee extensions (classical curve) and using instantaneous values from jumping exercises. RESULTS In the fascicle level, we did not find an enhanced muscle force in the jumping performances as compared with the classical force-velocity curve. In the muscle-tendon level, the instantaneous force at high muscle-tendon shortening speeds exceeded that extrapolated according to Hill's equation. CONCLUSION This difference between fascicle and muscle-tendon behaviour suggests that the neural input in fast stretch-shortening cycle exercises minimizes the length changes in muscle fascicle and enables storage and recoil of energy from elastic components that contributes to the enhanced mechanical output of the MTU during the push-off phase.

Abstract
OBJECTIVE Ankylosing spondylitis (AS) is a prototype of a group of rheumatic diseases referred to as spondyloarthropathy. AS patients show marked ectopic ossification in the spine, occasionally resulting in so-called bamboo spine. Although a strong association with HLA-B27 has been reported, its aetiology remains undetermined. Another rheumatic disease, ossification of the posterior longitudinal ligament of the spine (OPLL), demonstrates ectopic ossification of the spinal ligaments very similar to that of AS. Recently, nucleotide pyrophosphatase (NPPS) was implicated in the aetiology of OPLL: an Npps mutation was found to cause OPLL in mice, and an association between a polymorphism of the human NPPS gene and OPLL was identified. The clinical similarities between AS and OPLL led us to hypothesize that NPPS may also be implicated in the aetiology of AS. To elucidate the role of NPPS in the pathogenesis of AS, we examined serum NPPS activity and the possible association of the NPPS gene with AS. METHODS Forty-four Japanese patients with AS, 43 patients with OPLL, and age- and sex-matched normal volunteers took part in this study. We determined serum NPPS activity using high-performance liquid chromatography and examined the association between AS and NPPS using single nucleotide polymorphisms (SNPs) of the NPPS gene. RESULTS Serum NPPS activity in AS patients was significantly decreased compared with the controls (P < 0.0001). However, there was no association between AS and NPPS gene SNPs. CONCLUSION NPPS is implicated in the pathogenesis of AS.

Abstract
Mouse mutant ttw (tiptoe walking) is an excellent model for ectopic ossification. This mutant exhibits ossification in various soft tissues, which is histologically similar to human OPLL (ossification of posterior longitudinal ligament of the spine). We previously reported that ttw is caused by a nonsense mutation of the nucleotide pyrophosphatase (ENPP1) gene, and that a polymorphism of the human ENPP1 gene is associated with OPLL. These facts indicate that ENPP1 regulates ectopic ossification in vivo; however, the mechanism is unclear. ENPP1 is an ectoenzyme that generates phosphate (Pi) and pyrophosphate (PPi). PPi is a strong inhibitor of ossification. Abnormal Pi metabolism is observed in patients with OPLL, and diseases with abnormal Pi metabolism such as hypophosphatemic rickets are frequently complicated by ectopic ossification. These lines of evidence suggest Pi-PPi metabolism associated with ENPP1 may play an important role in regulation of ectopic ossification. To clarify the molecular mechanism of ectopic ossification in ttw, we examined the effect of dietary phosphate and calcium on the ttw phenotype and found a high dietary phosphate-accelerated ectopic ossification. Then we examined genes associated with the enhanced ossification in ttw on a high phosphate diet by a differential display method. We identified nine mouse genes; six genes were up-regulated by the high phosphate diet, and three were down-regulated. Six of the nine genes were novel and we cloned and characterized them. Two of the genes were highly specific to cartilage, suggesting their specific role in enchondral ossification. Our identification of the novel genes would give novel insight into the mechanism of ectopic ossification and etiology of OPLL.
