Scientists close in on mystery surrounding dangerous blood syndromes

(Cincinnati Children's Hospital Medical Center) Scientists may be on the road to solving the mystery of a group of mostly incurable blood diseases called myelodysplastic syndromes (MDS), which cause people to have immature, malfunctioning bone marrow cells that fuel a diverse set of health problems and can lead to leukemia. Researchers report in the journal Cancer Discovery identifying a gene that in laboratory experiments fuels the biological processes that cause the different types of MDS that physicians see in patients.

Conclusion: No statistically significant radiation associations were observed among 114,270 nuclear weapons test participants followed for up to 65 y. The 95% confidence limits were narrow and exclude mortality risks per unit dose that are two to four times those reported in other investigations. Significantly elevated SMRs were seen for mesothelioma and asbestosis, attributed to asbestos exposure aboard ships. PMID: 32602389 [PubMed - as supplied by publisher]

Authors: Zhang M, Luo J, Luo X, Liu L Abstract As a member of the cancer-testis antigen family, sperm-associated antigen 6 (SPAG6) has been reported to be associated with the pathogenesis of myelodysplastic syndromes (MDS). Previous studies have demonstrated that SPAG6 is upregulated in bone marrow from patients with MDS and MDS-transformed acute myeloid leukemia and that knockdown of SPAG6 expression levels suppressed proliferation and promote apoptosis and differentiation in SKM-1 cells. However, the association between SPAG6 and autophagy in SKM-1 cells remains unclear. Hence, the aim of the present study was to...

our M Abstract Microtransplantation (MT) is based on injection of HLA-mismatched G-CSF mobilized hematopoietic stem cells, in combination with chemotherapy but without use of conditioning regimen nor immunosuppressive drugs. As a result, a transient microchimerism is induced without engraftment. Its efficacy relies both on host immune system stimulation (recipient versus tumor) and on a graft versus tumor effect. Data are scarce and concern mostly Asian patients with acute myeloid leukemia (AML) and high risk myelodysplastic syndrome (HR-MDS). In comparison to conventional treatment without MT, higher complete rem...

g P Abstract The myelodysplastic syndromes (MDS) share an origin in the hematopoietic stem cell but have otherwise very heterogeneous biological and genetic characteristics. Clinical features are dominated by cytopenia and substantial risk for progression to acute myeloid leukemia. According to the World Health Organisation (WHO) MDS is defined by cytopenia, bone marrow dysplasia, and by certain karyotypic abnormalities. The understanding of disease pathogenesis has undergone major development with the implementation of next generation sequencing, and a closer integration of morphology, cytogenetics and molecular ...

AbstractPurpose of ReviewKnowledge of both somatic mutations and copy number aberrations are important for the understanding of cancer pathogenesis and management of myeloid neoplasms. The currently available standard of care technologies for copy number assessment such as conventional karyotype and FISH are either limited by low resolution or restriction to targeted assessment.Recent FindingsChromosomal microarray (CMA) is effective in characterization of chromosomal and gene aberrations of diagnostic, prognostic, and therapeutic significance at a higher resolution than conventional karyotyping. These results are compleme...

Abstract Mutations in spliceosomal components are prevalent in myelodysplastic syndromes, but less so in acute myeloid leukemia (AML). However, aberrant splicing is prolific in AML, suggesting deregulated splicing could contribute broadly to tumorigenesis. Elevated stress responses correlate with splicing dysfunction across myeloid malignancies, representing potentially novel therapeutic targets. PMID: 32317289 [PubMed - as supplied by publisher]
