摘要

Triple negative breast cancer (TNBC) is a highly aggressive form of breast cancer resistant to many common treatments. In this study, we compared the effects of 12 phytochemical drugs on four cancer cell lines, and noticed that Cucurbitacin E (CuE) significantly inhibited TNBC cell growth by inducing cell cycle G2/M phase arrest and apoptosis. CuE reduced expression of Cyclin D1, Survivin, XIAP, Bcl2, and Mcl-1 in MDA-MB-468 and SW527, and within MDA-MB-468, CuE significantly increased activation of JNK and inhibited activation of AKT and ERK. Collectively, these results suggest that CuE may be a viable compound for developing novel TNBC therapeutics.

Knockdown of Annexin A2 Enhances Radiosensitivity by Increasing G2/M-Phase Arrest, Apoptosis and Activating the p38 MAPK-HSP27 Pathway in Nasopharyngeal Carcinoma

Huocong He, Keyu Lin, Changyan Zou, Jianru Pan, Wankai Fu, Yan Zhou, Huamei Lin, Chao Chen, Ying Su

Summary: Annexin A2 (ANXA2) is associated with prognosis in nasopharyngeal carcinoma (NPC), with high expression leading to radioresistance. Knockdown of ANXA2 enhances radiosensitivity in NPC cells by inducing G2/M phase arrest, apoptosis, and activating the p38 MAPK-HSP27 pathway. ANXA2 may be a promising therapeutic target for overcoming radioresistance in NPC.

Chalcone-Acridine Hybrid Suppresses Melanoma Cell Progression via G2/M Cell Cycle Arrest, DNA Damage, Apoptosis, and Modulation of MAP Kinases Activity

Maria Gazdova, Radka Michalkova, Martin Kello, Maria Vilkova, Zuzana Kudlickova, Janette Baloghova, Ladislav Mirossay, Jan Mojzis

Summary: This study focused on investigating the antiproliferative effects of chalcone hybrids, particularly the chalcone-acridine hybrid 1C, in melanoma cancer cells. The study revealed that 1C exhibited potent antiproliferative effects by inducing cell cycle arrest and apoptosis. Additionally, the study found that 1C modulated the expression or phosphorylation of specific cell cycle-associated proteins and activated the DNA damage response pathway. Furthermore, 1C also induced apoptosis by causing mitochondrial dysfunction and activating caspase 3/7. The study suggests that the chalcone-acridine hybrid 1C may have potential as an antimelanoma agent in humans.

Plumbagin Exhibits Genotoxicity and Induces G2/M Cell Cycle Arrest via ROS-Mediated Oxidative Stress and Activation of ATM-p53 Signaling Pathway in Hepatocellular Cells

Huan Liu, Wenchao Zhang, Lijie Jin, Shasha Liu, Liying Liang, Yanfei Wei

Summary: This study investigates the anticancer mechanism of Plumbagin (PLB) and its potential connections with oxidative stress, genotoxicity, and cell cycle arrest. The results indicate that PLB significantly inhibits HCC cell viability and colony formation, induces G2/M cell cycle arrest, oxidative stress, and DNA damage. These effects can be attenuated by NAC pretreatment. PLB triggers a DNA damage response by activating ATM, Chk1, Chk2, and p53. Furthermore, the key modulator of the G2/M transition factor, cdc25C, is downregulated in an ROS-dependent manner. Inhibition of the ATM-p53 pathway can reduce the occurrence of G2/M cell cycle arrest. Therefore, ROS-mediated oxidative stress plays a crucial role in PLB-induced G2/M cell cycle arrest mediated by the ATM-p53 pathway.

Summary: Immunotherapy can induce durable clinical responses in some cancer patients, but resistance poses a major challenge. The expression of tumor STC1 is correlated with immunotherapy efficacy and negatively associated with patient survival across different cancer types. This study suggests that tumor STC1 may inhibit APC phagocytosis and contribute to tumor immune evasion and immunotherapy resistance.
