Abstract
Aplastic anemia (AA) is a lethal hematological disorder; however, its pathogenesis is not fully understood. Although immunosuppressive therapy (IST) is a major treatment option for AA, one-third of patients do not respond to IST and its resistance mechanism remains elusive. To understand AA pathogenesis and IST resistance, we performed single-cell RNA sequencing (scRNA-seq) of bone marrow (BM) from healthy controls and patients with AA at diagnosis. We found that CD34+ early-stage erythroid precursor cells and PROM1+ hematopoietic stem cells were significantly depleted in AA, which suggests that the depletion of CD34+ early-stage erythroid precursor cells and PROM1+ hematopoietic stem cells might be one of the major mechanisms for AA pathogenesis related with BM-cell hypoplasia. More importantly, we observed the significant enrichment of CD8+ T cells and T cell-activating intercellular interactions in IST responders, indicating the association between the expansion and activation of T cells and the positive response of IST in AA. Taken together, our findings represent a valuable resource offering novel insights into the cellular heterogeneity in the BM of AA and reveal potential biomarkers for IST, building the foundation for future precision therapies in AA.

The Sirt1 activator resveratrol improved hematopoiesis in pancytopenia mice induced by irradiation. J Pharmacol Sci 2019; 140:79-85. [PMID: 31178326 DOI: 10.1016/j.jphs.2019.05.004] [Citation(s) in RCA: 7] [Impact Index Per Article: 1.4] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 02/19/2019] [Revised: 04/25/2019] [Accepted: 05/08/2019] [Indexed: 01/08/2023] Open
Abstract
Bone marrow failure is a disease syndrome with the disability to produce mature blood cells. Pancytopenia is the most common manifestation of bone marrow failure. Sirt1 is important for the function of hematopoietic stem cells, we hypothesized that Sirt1 activation may improve hematopoiesis. The Sirt1 heterozygous and wild type mice were exposed to lethal 6.5 Gy 60Co-γ rays. The survival time and hematopoietic indexes were evaluated. The survival time of Sirt1 deficiency mice was significantly decreased. The numbers of platelets (PLT), reticulocytes (RET) and white blood cells (WBC) were significantly decreased. C57BL/6 mice were exposed to 6.5 Gy 60Co-γ rays then administrated with resveratrol (20 mg/kg/d) or vehicle. Resveratrol increased the survival time and protective against irradiation induced hematopoietic damage. Resveratrol also significantly increased the numbers of PLT, RET and WBC of mice. It also increased the hematopoietic area and karyocytes number. In HEK293T cells, the expression of LKB1 was significantly increased in cytoplasm but not in nuclei when treated with resveratrol (50 μM). These results suggest that Sirt1 deficiency might aggravate bone marrow failure. Resveratrol corrected this hematopoietic defect and LKB1 might involve in the protective effect on bone marrow failure.

Abstract
OBJECTIVES Osteoporosis is a chronic disease. The aim of this study was to identify key genes in osteoporosis. METHODS Microarray data sets GSE56815 and GSE56814, comprising 67 osteoporosis blood samples and 62 control blood samples, were obtained from the Gene Expression Omnibus database. Differentially expressed genes (DEGs) were identified in osteoporosis using Limma package (3.2.1) and Meta-MA packages. Gene Ontology and Kyoto Encyclopedia of Genes and Genomes enrichment analyses were performed to identify biological functions. Furthermore, the transcriptional regulatory network was established between the top 20 DEGs and transcriptional factors using the UCSC ENCODE Genome Browser. Receiver operating characteristic (ROC) analysis was applied to investigate the diagnostic value of several DEGs. RESULTS A total of 1320 DEGs were obtained, of which 855 were up-regulated and 465 were down-regulated. These differentially expressed genes were enriched in Gene Ontology terms and Kyoto Encyclopedia of Genes and Genomes pathways, mainly associated with gene expression and osteoclast differentiation. In the transcriptional regulatory network, there were 6038 interactions pairs involving 88 transcriptional factors. In addition, the quantitative reverse transcriptase-polymerase chain reaction result validated the expression of several genes (VPS35, FCGR2A, TBCA, HIRA, TYROBP, and JUND). Finally, ROC analyses showed that VPS35, HIRA, PHF20 and NFKB2 had a significant diagnostic value for osteoporosis. CONCLUSION Genes such as VPS35, FCGR2A, TBCA, HIRA, TYROBP, JUND, PHF20, NFKB2, RPL35A and BICD2 may be considered to be potential pathogenic genes of osteoporosis and may be useful for further study of the mechanisms underlying osteoporosis.Cite this article: B.

Abstract
Introduction von Voss-Cherstvoy syndrome is a part of a group of syndromes with radial and hematologic abnormalities, and until now approximately ten cases have been reported in the literature. This syndrome is characterized by a triad of radial ray defects, occipital encephalocele, and urogenital abnormalities. Case presentation We report a neonate from Indian ethnicity who was diagnosed with von Voss-Cherstvoy syndrome. The neonate had radial ray defect, occipital encephalocele, tetralogy of Fallot, and bilateral agenesis of kidney, ureter, and bladder. The neonate was suspected to have von Voss-Cherstvoy syndrome on the basis of clinical features, which was further confirmed by fibroblast analysis showing somatic mosaicism for del(13q). Conclusion von Voss-Cherstvoy syndrome is a very rare syndrome that can be suspected on the basis of typical clinical features and confirmed by fibroblast analysis showing somatic mosaicism for del(13q). This adds a second case of this chromosome anomaly described in this syndrome.

Abstract
Diamond-Blackfan Anemia (DBA) is a rare heterogeneous genetic disease characterized by severe anemia, reduction or absence of erythroid progenitors, and pro-apoptoptic hematopoiesis, which culminates in bone marrow failure. The disease generally manifests in infancy, as craniofacial, cardiac, genitourinary, and upper limb congenital anomalies. Therapy with corticoids is the treatment of choice, while blood transfusion is adopted during diagnosis and as a chronic approach if the patient does not respond to corticoids. This case report describes DBA in a patient that presented with lesions on the oral mucosa caused by secondary neutropenia. The stomatologist plays an important role in a transdisciplinary team and must remain attentive to the general health conditions of patients, since some oral lesions may be associated with systemic events.

Abstract
The inherited bone marrow failure syndromes (IBMFS) are a rare yet clinically important cause of neonatal hematological and non-hematological manifestations. Many of these syndromes, such as Fanconi anemia, dyskeratosis congenita and Diamond-Blackfan anemia, confer risks of multiple medical complications later in life, including an increased risk of cancer. Some IBMFS may present with cytopenias in the neonatal period whereas others may present only with congenital physical abnormalities and progress to pancytopenia later in life. A thorough family history and detailed physical examination are integral to the work-up of any neonate in whom there is a high index of suspicion for an IBMFS. Correct detection and diagnosis of these disorders is important for appropriate long-term medical surveillance and counseling not only for the patient but also for appropriate genetic counselling of their families regarding recurrence risks in future children and generations.

Abstract
Disruptions in ribosomal biogenesis would be expected to have global and in fact lethal effects on a developing organism. However, mutations in ribosomal protein genes have been shown in to exhibit tissue specific defects. This seemingly contradictory finding - that globally expressed genes thought to play fundamental housekeeping functions can in fact exhibit tissue and cell type specific functions - provides new insight into roles for ribosomes, the protein translational machinery of the cell, in regulating normal development and disease. Furthermore it illustrates the surprisingly dynamic nature of processes regulating cell type specific protein translation. In this review, we discuss our current knowledge of a variety of ribosomal protein mutations associated with human disease, and models to better understand the molecular mechanisms associated with each. We use specific examples to emphasize both the similarities and differences between the effects of various human ribosomal protein mutations. Finally, we discuss areas of future study that are needed to further our understanding of the role of ribosome biogenesis in normal development, and possible approaches that can be used to treat debilitating ribosomopathy diseases.
