Tumor necrosis factor ‑related apoptosis‑inducing ligand is a novel transcriptional target of runt‑related transcription factor 1
Int J Oncol. 2022 Jan;60(1):6. doi: 10.3892/ijo.2021.5296. Epub 2021 Dec 27.ABSTRACTRunt‑related transcription factor 1 (RUNX1), which is also known as acute myeloid leukemia 1 (AML1), has been frequently found with genomic aberrations in human leukemia. RUNX1 encodes a transcription factor that can regulate the expression of hematopoietic genes. In addition, tumor necrosis factor‑related apoptosis‑inducing ligand (TRAIL) performs an important function for malignant tumors in immune surveillance. However, the regulatory mechanism of TRAIL expression remain to be fully elucidated. In the present study, tetradecanoylph...

Sanguinarine Induces Apoptosis Pathway in Multiple Myeloma Cell Lines via Inhibition of the JaK2/STAT3 Signaling
In this study, we aimed to investigate the potential anti-proliferative and pro-apoptotic activities of SNG in a panel of MM cell lines (U266, IM9, MM1S, and RPMI-8226). SNG treatment of MM cells resulted in a dose-dependent decrease in cell viability through mitochondrial membrane potential loss and activation of caspase 3, 9, and cleavage of PARP. Pre-treatment of MM cells with a universal caspase inhibitor, Z-VAD-FMK, prevented SNG mediated loss of cell viability, apoptosis, and caspase activation, confirming that SNG-mediated apoptosis is caspase-dependent. The SNG-mediated apoptosis appears to be resulted from suppres...

Resveratrol inhibits STAT5 activation through the induction of SHP-1 and SHP-2 tyrosine phosphatases in chronic myelogenous leukemia cells
STAT5 is an important transcription factor that is constitutively activated in various types of malignancies, including chronic myelogenous leukemia (CML). Whether the antitumor effects of resveratrol (RES) are linked to its capability to inhibit STAT5 activation in CML cells was investigated. We found that RES inhibited STAT5 activation in K562 and KU812 cell lines; RES also reduced the STAT5 concentration in the nucleus of K562 and KU812 cells. Protein tyrosine phosphatase (PTP) inhibitor, sodium pervanadate, reversed the RES-induced downregulation of STAT5, suggesting the involvement of a PTP. Indeed, we observed that R...
