Purpose: Leukemia causes tremendous human mortality especially in children and young adults. This study was undertaken to investigate the anticancer effects of Solanine against the normal human NCI-H526 and human leukemia AML-193 cell lines.
Methods: Cell proliferation was determined by MTT assay. DAPI and annexin V/propidium iodide (PI) assays were used for the determination of apoptosis. The expression analysis was done by qRT-PCR. Protein concentrations were determined by western blot analysis.
Results: DAPI staining showed that Solanine causes nuclear morphological changes. The annexin V/PI staining showed that Solanine increased the leukemia apoptotic cell death dose-dependently. The expression of Bax was increased while of Bcl-2 was decreased. The qRT-PCR analysis showed that microRNA (miR)-16 was significantly (p<0.05) downregulated in leukemia AML-193 cells as compared to normal NCI-H526 cells.
Conclusion: Taken together, these results showed that Solanine inhibits the proliferation of leukemia cells via induction of apoptosis and modulation of miR-16/Bcl-2 axis.

Hematopoietic stem cells must mitigate myriad stressors throughout their lifetime to ensure normal blood cell generation. Here, we uncover unfolded protein response stress sensor inositol-requiring enzyme-1α (IRE1α) signaling in hematopoietic stem and progenitor cells (HSPCs) as a safeguard against myeloid leukemogenesis. Activated in part by an NADPH oxidase-2 mechanism, IRE1α-induced X-box binding protein-1 (XBP1) mediated repression of pro-leukemogenic programs exemplified by the Wnt-β-catenin pathway.

Acute Myeloid Leukemia (AML) with KMT2A rearrangements (KMT2Ar), found on chromosome 11q23, is often called KMT2A-rearranged AML (KMT2Ar-AML). This variant is highly aggressive, characterized by rapid disease progression and poor outcomes. Growing knowledge of epigenetic changes, especially lactylation, has opened new avenues for investigation and management of this subtype.

Objectives: Monitoring minimal residual disease (MRD) and timely intervention are effective strategies for preventing relapse after allogeneic hematopoietic stem cell transplantation (allo-HSCT) in adult acute myeloid leukemia (AML). The gene, a pan-leukemia marker, can be used as an indicator for MRD monitoring in AML patients. Currently, there is no unified standard for the intervention timing or treatment threshold based on gene detection after transplantation.
