In conclusion, we confirmed that ATPR could induce SKM-1 cells differentiation and its positive influence of DDX23 may provide a new idea to relieve MDS.

Combretastatin A1 (OXi4503) is a dual-function drug with vascular disrupting and cytotoxic properties that has exhibited single-agent anti-leukemia activity in murine xenograft models of acute myeloid leukemia (AML) and in a prior Phase 1A clinical study for relapsed/refractory (R/R) AML. The purpose of the present multicenter Phase 1B study was to define the maximum tolerated dose (MTD) and safety profile of OXi4503 and cytarabine (ARA-C) administered in combination (OXA). At four centers, 29 patients with R/R AML or myelodysplastic syndrome (MDS) were treated with OXA. The most common grade 3/4 treatmen…

In this study, by adenovirus-mediated delivery and inducible transgenic mouse models, we demonstrate the proliferation of both HCs and SCs by combined Notch1 and Myc activation in in vitro and in vivo inner ear adult mouse models. These proliferating mature SCs and HCs maintain their respective identities. Moreover, when presented with HC induction signals, reprogrammed adult SCs transdifferentiate into HC-like cells both in vitro and in vivo. Finally, our data suggest that regenerated HC-like cells likely possess functional transduction channels and are able to form connections with adult auditory neurons.

ConclusionsOral complications in HSCT survivors are common and may include GVHD, dry mouth, and taste changes. All patients must be screened prior to HSCT and followed up by a dentist periodically to assess the oral health status and modify treatment, if needed.

This study is registered with Clinicaltrials.gov, number NCT02560025, and has completed enrolment.FindingsBetween Dec 31, 2015, and Aug 1, 2017, we enrolled a total of 39 eligible patients. 19 (49%) of 39 patients had secondary acute myeloid leukaemia and three (8%) had therapy-related acute myeloid leukaemia. At mid-induction, 33 (85%) of 39 patients showed marrow aplasia, six (15%) received re-induction. The median follow-up was 13·7 months (IQR 12·7–14·4). Composite remission was 64% (two-stage 95% CI 48–79), with 20 (51%) of 39 patients achieving complete remission and five (13%) achiev…

Abstract
Often unrecognized and underdiagnosed, myelodysplastic syndromes (MDS) are a rare group of cancers in which the bone marrow fails to produce sufficient healthy blood cells. Although patients with lower-risk MDS can live for>5 years, those with high-risk disease that evolves into acute myeloid leukemia is associated with significantly lower overall survival. At the NCCN 2019 Annual Congress: Hematologic Malignancies, Dr. Rafael Bejar summarized current standard treatment options for patients with MDS and discussed the importance of genetic testing to identify mutations that may impact tr…

Publication date: Available online 22 November 2019Source: Journal of Geriatric OncologyAuthor(s): Reena Jayani, Ashley Rosko, Rebecca Olin, Andrew ArtzAbstractHematopoietic cell transplant (HCT) is an important aspect of treatment for many hematologic malignancies. As cancer is a disease associated with aging, and hematologic malignancies are no exception, rates of autologous and allogeneic HCT utilization in older adults are on the rise. The most common indications for autologous HCT are multiple myeloma and lymphoma, and for allogenic HCT are acute myeloid leukemia and myelodysplastic syndrome. Older adults into their e…

Components of the pre-messenger RNA splicing machinery are frequently mutated in myeloid malignancies. Mutations in LUC7L2, PRPF8, SF3B1, SRSF2, U2AF1, and ZRSR2 genes occur at various frequencies ranging between 40% and 85% in different subtypes of myelodysplastic syndrome (MDS) and 5% and 10% of acute myeloid leukemia (AML) and myeloproliferative neoplasms (MPNs). In some instances, splicing factor (SF) mutations have provided diagnostic utility and information on clinical outcomes as exemplified by SF3B1 mutations associated with increased ring sideroblasts (RS) in MDS-RS or MDS/MPN-RS with thrombocytosis. SF3…
