A novel piperine derivative HJJ_3_5 inhibits colorectal cancer progression by modulating EMT signaling pathways.

Colorectal cancer (CRC) is a fatal cancer prevalent worldwide, and epithelial-mesenchymal transition (EMT) is a key factor in tumor invasion and metastasis. Piperine, a natural alkaloid known for its antitumor properties, faces limitations in clinical use due to its moderate potency. To address this, our team synthesized and validated a new derivative, HJJ_3_5, which has shown potent antitumor activity against CRC cells.

Identification of MORF4L1 as an endogenous substrate of CRBN and its potential role as a therapeutic target in cancer.

The ubiquitin-proteasome system (UPS) is essential for cellular homeostasis, regulating the degradation of proteins involved in key processes such as cell cycle, apoptosis, and DNA repair. Dysregulation of the UPS is implicated in hepatocellular carcinoma (HCC), contributing to tumor progression and therapeutic resistance. The cereblon (CRBN) E3 ubiquitin ligase complex is a crucial component of the UPS, particularly in modulating protein degradation in response to small-molecule modulators like thalidomide.

Tissue-resident memory T cells in diseases and therapeutic strategies.

Tissue-resident memory T (T) cells are crucial components of the immune system that provide rapid, localized responses to recurrent pathogens at mucosal and epithelial barriers. Unlike circulating memory T cells, T cells are located within peripheral tissues, and they play vital roles in antiviral, antibacterial, and antitumor immunity. Their unique retention and activation mechanisms, including interactions with local epithelial cells and the expression of adhesion molecules, enable their persistence and immediate functionality in diverse tissues.

CD83 mediates the inhibitory effect of the S1PR1 agonist CYM5442 on LPS-induced M1 polarization of macrophages through the ERK-STAT-1 signaling pathway.

Macrophages possess M1/M2 polarization, which perform an essential role in immunology and inflammation studies. However, few studies have investigated the specific molecules involved in the polarization process beyond its induction and characterization. Here, we determined that the molecule S1PR1 regulates M1 polarization in macrophages and that the surface marker CD83 is involved in this process.
