AI Article Synopsis

  • SPAG1 is linked to infertility and tumor development, with its role in acute myeloid leukemia (AML) being investigated for the first time.
  • High expression levels of SPAG1 in AML patients correlate with poor prognosis, but do not relate to FLT3 mutations.
  • Experiments reveal that SPAG1 supports AML cell growth and survival by influencing certain signaling pathways, suggesting it could be a potential target for future treatments.

Article Abstract

Sperm-associated antigen 1 (SPAG1) is considered to be associated with infertility and tumorigenesis. However, its function in acute myeloid leukemia (AML) remains unclear. In this study, we evaluated the expression level of SPAG1 and explored its clinical prognostic value in patients with AML, as well as its biological function in AML cells. SPAG1 is widely expressed in AML patients, resulting in a poor prognosis. However, its expression was not associated with Fms-related receptor tyrosine kinase 3 (FLT3) mutations. Utilizing the RNA interference knockdown tests, we found that SPAG1 could promote the proliferation and survival of AML cells and regulate the expression of structural maintenance of chromosomes protein 3 (SMC3), activating the ERK/MAPK signaling pathway. Furthermore, we discovered that inhibiting SPAG1 impacted AML cell susceptibility to venetoclax. In conclusion, SPAG1 may serve as a potential therapeutic target in AML.

Background/aim: Blastic plasmacytoid dendritic cell neoplasm (BPDCN) is a rare and highly aggressive hematologic cancer which is difficult to diagnose and has a lot of overlapping features with other diseases, particularly acute myeloid leukemia (AML). BPDCN shares several immunophenotypic markers with AML, such as CD4, CD56, CD123, and HLA-DR, stating the importance of having extending panel of specific immunohistochemical (IHC) markers.

Case Report: This report details a case of CLL who presented with worsening symptoms of recurrent infections and leukocytosis.

N-methyladenosine (mA) is a crucial mRNA epigenetic modification in eukaryotes, and its methylation regulation is associated with the proliferation and metastasis of diverse tumor cells. ALKBH5 functions as a demethylase for mA and plays a role in the demethylation process, thus influencing tumor cell growth and migration. However, there are limited reports on selective small molecule inhibitors of ALKBH5.

Molecular assessment of measurable residual disease (MRD) in NPM1-mutated AML patients is a powerful prognostic tool to identify the risk of relapse. There is limited data regarding MRD-guided decisions against alloSCT in elderly patients and FLT3-ITD co-mutation. We describe the outcome of NPM1-mutated AML patients in whom alloSCT was deferred based on ELN 2017 risk and MRD response.
