Article Abstract
Luteolin, 3',4',5,7-tetrahydroxyflavone, a natural flavonoid component found in various Chinese herbs such as Scutellaria barbata D. Don, honeysuckle, chrysanthemum, schizonepeta, and ajuga decumbens, exhibits potential for cancer prevention and therapy. This study elucidates the molecular mechanisms by which luteolin, an active constituent of Scutellaria barbata, inhibits invasion and metastasis of hepatocellular carcinoma (HCC) cell lines both in vitro and in vivo. The oncogenic microRNA miR-6809-5p was found to be aberrantly upregulated in HCC tissues and downregulated by luteolin in HCC cells; overexpression of miR-6809-5p was able to restore the anti-HCC effects of luteolin via the miR-6809-5p/FLOT1/FAK signaling pathway. Furthermore, luteolin suppressed HCC invasion, metastasis, and epithelial-mesenchymal transition (EMT) through modulation of the PI3K/AKT/mTOR pathway, affecting markers such as E-cadherin, β-catenin, Vimentin, N-cadherin, Snail, Twist, and Slug. This research demonstrates that luteolin effectively inhibits HCC cell migration and invasion and significantly suppresses epithelial mesenchymal transition (EMT) both in vitro and in vivo.

Triple-negative breast cancer (TNBC) is the most aggressive breast cancer subtype, characterized by a high propensity for metastasis, poor prognosis, and limited treatment options. Research has demonstrated a substantial correlation between the expression of protein arginine N-methyltransferase 1 (PRMT1) and enhanced proliferation, metastasis, and poor outcomes in TNBC. However, the specific role of PRMT1 in lung metastasis and chemoresistance remains unclear.

Neutrophil extracellular traps (NETs) are DNA-protein structures released during a form of programmed neutrophil death known as NETosis. While NETs have been implicated in both tumor inhibition and promotion, their functional role in cancer remains ambiguous. In this study, we compared the NET-forming capacity and functional effects of NETs derived from lung cancer (LC) patients and healthy donors (H).

The stress distribution in Li metal strongly affects the interfacial Li-ion diffusion, thereby influencing the morphology of plated Li and the performance of the battery. Here, we report a mechano-electrochemical coupling strategy that utilizes an arched structured carbon aerogel to achieve stable Li-plating/stripping electrochemistry. The arch-structured carbon aerogel can actively regulate stress distributions in response to the compressive stresses induced by Li deposition, generating the transition of stress from compressive on the convex surface to tensile on the concave surface, which can effectively promote the Li-migration kinetics and thus suppress the non-uniform deposition of Li.

Background: Insulinoma, the most common type of pancreatic endocrine tumor, frequently induces hypoglycemia due to persistent hyperinsulinemia. Although Mi-Lnc70 expression progressively increases during pancreatic maturation in mice, the biological role of Mi-Lnc70 in pancreatic β cells remains elusive.
Aim: This study was designed to investigate the role of LncRNA-Mi-Lnc70 in the mouse pancreatic β-cell line MIN6.

Endometrial cancer (EC) is one of the most common gynecological cancers in developed countries. Like EC, most female reproductive tract malignancies are thought to be hormonally driven, with estrogen signaling acting as an oncogenic signal. The actions of estrogen are mediated through the classical nuclear estrogen receptors α (ER-α) and β (ER-β) as well as transmembrane G protein-coupled estrogen receptors (GPR30 and GPER).
