To investigate the potential effects of pure total flavonoid compounds (PTFCs) from Citrus paradisi Macfadyen separately or combined with arsenic trioxide on the proliferation of human myeloid leukemia cells and the mechanisms underlying the action of PTFCs. The effects of PTFCs separately or combined with arsenic trioxide on the proliferation and apoptosis of leukemia cells were determined by 3-(4,5-dimethylthiazol-2-yl)-2,5-diphenyltetrazolium bromide (MTT), fluorescence microscopy, and flow cytometry. Their effects on the expression levels of apoptosis-related regulators were determined by Western blot assay. PTFCs combined with arsenic trioxide significantly inhibited the growth of Kasumi-1 cells, and apoptosis was confirmed by flow cytometry analysis. Hoechst 33258 staining showed more significant morphological changes and more apoptosis following the combined treatment. Western blots showed changes in the expression of genes for poly ADP-ribose polymerase (PARP), caspase 3/9, and P65. The results indicated that PTFCs separately or combined with arsenic trioxide inhibited proliferation of leukemia cells in vitro and induced their apoptosis by modulating the expression of apoptosis-related regulator genes.

RET tyrosine kinase, a key regulator of cellular signaling, is abnormally activated due to mutations or fusions in various cancers, making it an important therapeutic target. Traditional multi-kinase inhibitors (MKIs, such as cabozantinib and vandetanib) exhibit significant side effects due to non-selective inhibition of targets like VEGFR, and also suffer from resistance associated with RET mutations (e.g.

Following the publication of this paper, it was drawn to the Editor's attention by a concerned reader that, for the western blots shown in Fig. 4C, the two left lanes in the 'Fibrillarin' gel slice appeared to be strikingly similar to the mirrored two right lanes in the 'Actin' gel slice, albeit the orientations of the blots were horizontally reversed, such that data which were intended to have shown the results of differently performed experiments appeared to have been derived from the same original source. Moreover, the control β-actin blots featured in Fig.

Arsenic trioxide (ATO) in combination with all-trans retinoic acid (ATRA) has been shown to be effective in both adult and pediatric patients with acute promyelocytic leukemia (APL). Addition of ATO to conventional chemotherapy could lead to a reduction in the doses of cytotoxic agents, but the long-term safety of ATO is not fully understood, especially in children. The Japan Children's Cancer Group conducted a risk-stratified prospective study to investigate safety and efficacy of ATO in children with newly diagnosed APL by replacing all three intensification phases with ATO.

Background: Acute promyelocytic leukemia (APL) is a subtype of acute myeloid leukemia (AML) characterized by the t(15;17) translocation, leading to the PML-RARA fusion gene. While treatable, APL presents significant challenges, particularly in resource-constrained settings where delays in diagnosis and access to specialized care may impact outcomes. This study aims to describe the clinical presentation, treatment outcomes, and survival data for pediatric APL patients.

Polyploid giant cancer cells (PGCCs) play an important role in regulating heterogeneity, growth, and chemotherapy resistance of malignant tumors. Paxillin is a unique cytoskeletal protein and drives persistent migration. In this study, we investigated the molecular mechanism by which paxillin regulates the invasion and migration of PGCCs with daughter cells (PDCs).
