However, poor and slow hematopoi- etic reconstitution remains a significant complication, which is correlated with abnormal hematopoietic stem-cell (HSC) func- tion. The maintenance and the preservation of HSC functional properties are supported by a highly specialized microenviron- ment within the bone marrow (BM), in which BM-derived mesenchymal stem cells (BMSCs) serve as the essential structural and functional basis for constituting the BM microenviron-ment. Damage, such as that due to chemotherapy, radiother- apy or inflammation, delays hematopoietic recovery or causes hematopoiesis dysfunction or failure, seriously affecting HSCT efficacy. 1 The key to remodeling and repairing the BM micro-environment lies in the repair of the niche structure by cellular therapies which include BMSCs. Research has increasingly confirmed that the most crucial functions of BMSCs are to main- tain the turnover of the BM stroma and skeletal tissues and to provide critical hematopoietic support. 2 However, the underly-ing mechanisms that regulate these different functions are not well known. In the recent BLOOD publication, the Dr. Zhao and Dr. Jiang group revealed that the retinoic acid-inducible gene I (RIG-I) plays a substantial role in regulating the stromal niche for hematopoietic reconstitution. 3 All-trans retinoic acid (ATRA) and inflammation stress upregulated RIG-I expres- sion, thus damaging the clonogenicity, the bone-forming ability of BMSCs and the supporting function in the stromal niche; mechanistically, this is achieved by suppressing the antioxidant impact of nuclear","PeriodicalId":67343,"journal":{"name":"血液科学(英文)","volume":"4 3","pages":"179-180"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/b9/9b/bs9-4-179.PMC9742105.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10731050","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Due to its rarity, little is known about the genetic and molecular characteristics, optimal treatment modalities, and prognostic factors of adult T-LBL. Therefore, we summarized the existing studies to comprehensively discuss the above issues in this review. Genetic mutations of NOTCH1/FBXW7, PTEN, RAS, and KMT2D, together with abnormal activation of signaling pathways, such as the JAK-STAT signaling pathway were described. We also discussed the therapeutic modalities. Once diagnosed, adult T-LBL patients should receive intensive or pediatric acute lymphoblastic leukemia regimen and central nervous system prophylaxis as soon as possible, and cranial radiation-free protocols are appropriate. Mediastinal radiotherapy improves clinical outcomes, but adverse events are of concern. Hematopoietic stem cell transplantation may be considered for adult T-LBL patients with high-risk factors or those with relapsed/refractory disease. Besides, several novel prognostic models have been constructed, such as the 5-miRNAs-based classifier, 11-gene-based classifier, and 4-CpG-based classifier, which have presented significant prognostic value in adult T-LBL.","PeriodicalId":67343,"journal":{"name":"血液科学(英文)","volume":"4 3","pages":"155-160"},"PeriodicalIF":0.0,"publicationDate":"2022-07-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://www.ncbi.nlm.nih.gov/pmc/articles/PMC9742094/pdf/","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10712763","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Recently, emerging studies have illustrated the cellular and molecular mechanisms underlying the regulation of HSC homeostasis. Particularly, the rapid development of second-generation sequencing technologies has uncovered that many small noncoding RNAs (ncRNAs) are highly expressed in HSCs, including snoRNAs, miRNAs, tsRNAs, circular RNAs, etc. In this study, we will summarize the essential roles and regulatory mechanisms of these small ncRNAs in maintaining HSC homeostasis.

Angiopoietin-like proteins (Angptls) are a group of secreted glycoproteins that have been reported to play various roles, including the regulation of HSC activity. 1 Speci ﬁ cally, Angptl2, a member of the Angptl family, was demonstrated to support HSC stemness through binding to inhibitory receptors. 2 Angptl2 has also been shown to support HSC activity in exosomes. 3 However, whether and how Angptl2 regulates HSC activities in the HSC niche were still unknown. Yu et al used an elegant approach to study these questions. 1 Based on the expression pattern of Angptl2 in bone marrow, several conditional knockout (KO) mice were generated to deplete Angptl2 from endothelial, mesenchymal stromal cells, megakaryocytes, and HSCs. Using a number of functional assays, including reconstitution analysis, ﬂ ow cytometry, and immuno ﬂ uorescence microscopy, the authors discovered that only endothelial cell-derived Angptl2 but not Angptl2 from other niche cell types supported the repopulation capacity, quiescent status, and niche localization of HSCs. They further demonstrated that Angptl2 enhances peroxisome-proliferator-activated receptor D expression to transactivate G0s2 and sustain the perinuclear localization of nucleolin that prevents HSCs from entering the cell cycle. study HSCs","PeriodicalId":67343,"journal":{"name":"血液科学(英文)","volume":"4 2","pages":"99"},"PeriodicalIF":0.0,"publicationDate":"2022-04-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"https://ftp.ncbi.nlm.nih.gov/pub/pmc/oa_pdf/e3/fd/bls-4-99.PMC9354721.pdf","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"10798013","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"OA","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
