Article Abstract
Glioma is a common malignant tumor in nervous system, but the treatment efficacy is still unsatisfactory. Licochalcone A (Lic-A) is a kind of flavonoid isolated from glycyrrhiza and shows anti-tumor effect. This study aimed to investigate anti-tumor efficacy of Lic-A on glioma using both in vivo and in vitro models. The in vitro results showed that Lic-A inhibited the growth, migration, and invasion of glioma cells in a dose-dependent way. Lic-A induced mitochondrial dysfunction by regulating Bcl-2 family and induced reactive oxygen species (ROS), while ROS inhibition enhanced the migration and invasion of glioma cells. Finally, animal experiments confirmed that Lic-A inhibited the growth of glioma in vivo. In conclusion, our results suggest that Lic-A can inhibit the migration and invasion of glioma cells while inducing apoptosis of glioma cells. The mechanism may be related to the activation of ATM/ATR pathway and the induction of oxidative stress.

Noncoding RNA regulatory networks play crucial roles in human breast cancer. The aim of this study was to establish a network containing multi-type RNAs and RBPs in triple-negative breast cancer (TNBC). Differential expression analyses of lncRNAs, miRNAs, and genes were performed using the GEO2R tool.

Long non-coding RNA MALAT1 regulates epithelial-mesenchymal transition (EMT) and metastasis in epithelial ovarian cancer (EOC) through a competing endogenous RNA (ceRNA) mechanism involving miRNA modulation. This study aimed to elucidate the molecular pathway by which MALAT1 influences EMT and metastatic behavior via interaction with miR-200c-3p and SNAI2. MALAT1 expression was genetically manipulated in the EOC cell line SK-OV-3 by either overexpression or knockdown.

Alterations in the structure of the Golgi apparatus play a pivotal role in cancer progression and invasion. A better understanding of how Golgi morphology regulates the metastatic potential of cancer cells could help identify potential treatment strategies. In this study, we investigated how specific structural variations in the Golgi, particularly fragmentation and condensation, influence the malignancy of gastric cancer using human cell lines, xenograft mouse models, and human patient tissue samples.
