Breast Cancer-Secreted Factors Promote Lung Metastasis by Signaling Systemically to Induce a Fibrotic Premetastatic Niche.

Unlabelled: Metastatic cancer is largely incurable and is the main cause of cancer-related deaths. The metastatic microenvironment facilitates formation of metastases. Cancer-associated fibroblasts (CAF) are crucial players in generating a hospitable metastatic niche by mediating an inflammatory microenvironment.

Cell-Type-Specific Effects of Silibinin on Vitamin D-Induced Differentiation of Acute Myeloid Leukemia Cells Are Associated with Differential Modulation of RXRα Levels.

Plant polyphenols have been shown to enhance the differentiation of acute myeloid leukemia (AML) cells induced by the hormonal form of vitamin D(3) (1α,25-dihydroxyvitamin D(3); 1,25D). However, how these agents modulate 1,25D effects in different subtypes of AML cells remains poorly understood. Here, we show that both carnosic acid (CA) and silibinin (SIL) synergistically enhancd 1,25D-induced differentiation of myeloblastic HL60 cells.
