A naturally derived small molecule compound suppresses tumor growth and metastasis in mice by relieving p53-dependent repression of CDK2/Rb signaling and the Snail-driven EMT.

The tumor suppressor protein p53 is central to cancer biology, with its pathway reactivation emerging as a promising therapeutic strategy in oncology. This study introduced LZ22, a novel compound that selectively inhibits the growth, migration, and metastasis of tumor cells expressing wild-type p53, demonstrating ineffectiveness in cells devoid of p53 or those expressing mutant p53. LZ22's mechanism of action involves a high-affinity interaction with the histidine-96 pocket of the MDM2 protein.

The antibiotic drug trimethoprim suppresses tumour growth and metastasis via targeting Snail.

Background And Purpose: The zinc finger transcription factor Snail is aberrantly activated in many human cancers and strongly associated with poor prognosis. As a transcription factor, Snail has been traditionally considered an 'undruggable' target. Here, we identified a potent small-molecule inhibitor of Snail, namely trimethoprim, and investigated its potential antitumour effects and the underlying mechanisms.

Omeprazole suppresses aggressive cancer growth and metastasis in mice through promoting Snail degradation.

Omeprazole is a proton pump inhibitor that has recently been reported to exhibit anticancer activity against several types of cancer. However, the anticancer mechanisms of omeprazole remain elusive. Snail is an oncogenic zinc finger transcription factor; aberrant activation of Snail is associated with the occurrence and progression of cancer.

A potent CBP/p300-Snail interaction inhibitor suppresses tumor growth and metastasis in wild-type p53-expressing cancer.

The zinc finger transcription factor Snail is aberrantly activated in many human cancers and associated with poor prognosis. Therefore, targeting Snail is expected to exert therapeutic benefit in patients with cancer. However, Snail has traditionally been considered "undruggable," and no effective pharmacological inhibitors have been identified.

Chamaejasmin B Decreases Malignant Characteristics of Mouse Melanoma B16F0 and B16F10 Cells.

Chamaejasmin B (CHB), a natural biflavone isolated from L., has been reported to exhibit anti-cancer properties; however, its effect in melanoma cells is not clear. Here, we aimed to investigate the anticancer effect of CHB in mouse melanoma B16F0 and B16F10 cells.

Inactivation of endothelial ZEB1 impedes tumor progression and sensitizes tumors to conventional therapies.

Current antiangiogenic therapy is limited by its cytostatic property, scarce drug delivery to the tumor, and side toxicity. To address these limitations, we unveiled the role of ZEB1, a tumor endothelium-enriched zinc-finger transcription factor, during tumor progression. We discovered that the patients who had lung adenocarcinomas with high ZEB1 expression in tumor endothelium had increased prevalence of metastases and markedly reduced overall survival after the diagnosis of lung cancer.

Alteronol Enhances the Anti-tumor Activity and Reduces the Toxicity of High-Dose Adriamycin in Breast Cancer.

The first-line chemotherapy drug adriamycin (ADM) is widely used for the treatment of breast cancer, but the acquired drug resistance and the normal tissue toxicity remain clinical challenges. Alteronol has been reported to exert wide-ranging anti-tumor activity. In this study, we firstly examined the synergistic anti-tumor effects and the underlying mechanisms of alteronol combined with ADM in breast cancer.

Low Dose of Acacetin Promotes Breast Cancer MCF-7 Cells Proliferation Through the Activation of ERK/ PI3K /AKT and Cyclin Signaling Pathway.

Background: Phytoestrogens have been proposed as replaceable medicines for climacteric hormone replacement therapy, on the basis of EP3138562 and US5516528. However, recent studies demonstrated that phytoestrogens might promote the proliferation of breast cancer cells, which is rooted in their estrogenic activity. Acacetin, as one phytoestrogen, has been reported to exhibit estrogenic activity.

Licochalcone D induces apoptosis and inhibits migration and invasion in human melanoma A375 cells.

The aim of the present study was to determine the effects of Licochalcone D (LD) on the apoptosis and migration and invasion in human melanoma A375 cells. Cell proliferation was determined by sulforhodamine B assay. Apoptosis was assessed by Hoechst 33258 and Annexin V‑FITC/PI staining and JC‑1 assay.

Alteronol induces cell cycle arrest and apoptosis via increased reactive oxygen species production in human breast cancer T47D cells.

Objective: Emerging evidence showed that alteronol has a potential antitumour effect in several tumour cells. However, the antitumour effect of alteronol on breast cancer has not been reported. This study investigated the mechanisms of alteronol-induced cell proliferation inhibition in human breast cancer T47D cells.

HMGB1 exacerbates bronchiolitis obliterans syndrome via RAGE/NF-κB/HPSE signaling to enhance latent TGF-β release from ECM.

Bronchiolitis obliterans syndrome (BOS), characterized by progressive airflow obstruction, is the main barrier to long-term graft survival after lung transplantation. Despite extensive studies, the mechanisms underlying BOS remain poorly understood, and targeted interventions have not yet been fully developed. In the present study, we employed a mouse model of tracheal transplantation and demonstrated that blockade of HMGB1 alone or combined with heparanase (HPSE) attenuates the development of BOS.
