Article Abstract
Clinical studies have demonstrated that omacetaxine mepesuccinate exerts beneficial effects on acute myelogenous leukemia. It has been suggested that omacetaxine mepesuccinate, used alone or with interferon‑α or cytarabine, induces remission in patients with chronic myelogenous leukemia. These effects are possibly mediated by its ability to induce apoptosis of leukemia cells and inhibit the activity of telomerase. To determine whether omacetaxine mepesuccinate is beneficial in diffuse large B‑cell lymphoma (DLBCL), two DLBCL cell lines [a germinal center B cell‑like subtype (GCB) and an activated B cell‑like subtype (ABC)] were treated with omacetaxine mepesuccinate at various concentrations for different durations. The present study indicated that omacetaxine mepesuccinate exerts proapoptotic effects in the two cell types in a dose‑ and time‑dependent manner. The ABC subtype demonstrated increased sensitivity compared with the GCB subtype. At 40 ng/ml, omacetaxine mepesuccinate exhibited a marked proapoptotic effect on DLBCL cells compared with the other tumor cells investigated. Furthermore, omacetaxine mepesuccinate induced cell cycle arrest at G0/G1 phase, and promoted cell terminal differentiation of pro‑B cells. The present study also demonstrated that omacetaxine mepesuccinate exerted its antitumor effect by reducing telomerase activity. In conclusion, the present study demonstrated that omacetaxine mepesuccinate may induce apoptosis and cell cycle arrest, promote cell differentiation, and reduce telomerase activity in DLBCL cells, thus aiding the development of omacetaxine mepesuccinate‑based DLBCL therapeutic strategies.

Mitochondrial-targeting strategies with homoharringtonine: A novel approach for chemoresistant rectal cancer.

5-Fluorouracil (5-FU) resistance poses a significant challenge in the treatment of rectal cancer, driving the need for novel therapeutic strategies. In this study, we established 5-FU-resistant rectal cancer cell lines (SW837-r, SNU-C1-r) and identified homoharringtonine (HHT) as a potent and selective anticancer agent through high-throughput drug screening of 291 compounds. HHT displayed the highest selective drug sensitivity score (sDSS), showing strong activity against resistant cells while sparing normal rectal epithelial cells.

Objectives: A combination of hypomethylation agents (HMA) and the HAG regimen (homoharringtonine, cytarabine, G-CSF) shows promise as a treatment for Acute Myeloid Leukemia (AML). Nevertheless, the clinical efficacy of this combined therapy in contrast to the HAG regimen alone remains uncertain.
Methods: We conducted a meta-analysis of eligible studies comparing the clinical efficacy of these two regimens.

Objective: This cohort study aimed to examine the impact of the FLT3-ITD mutation on the downstream signaling pathway of PI3K/AKT pathway, the percentage of leukemia stem cells, and the survival of patients receiving D3A7 induction therapy.
Method: Bone marrow mononuclear cells were collected from 20 adult AML patients who had completed D3A7 induction therapy at Cipto Mangunkusumo National General Hospital and Dharmais Cancer Hospital. FLT3-ITD gene mutation was examined by the PCR-sequencing method.

Absence of SMARCB1 in rhabdoid tumor cells increases sensitivity to translation inhibition and alters translation efficiency of specific mRNAs.
J Biol Chem

Department of Pathology, Stanford University, Stanford, California, USA. Electronic address:
Rhabdoid tumors, characterized and driven by the loss of the mammalian SWItch/sucrose nonfermentable subunit SMARCB1, are very aggressive childhood cancers that can arise in the brain, the kidney, or soft tissues. Cell lines derived from these tumors are specifically sensitivity to the translation inhibitor homoharringtonine. Having recently demonstrated mammalian SWItch/sucrose nonfermentable roles in translation, we assessed SMARCB1 potential roles in translation in rhabdoid tumor cells.
