BACKGROUND: Tocotrienols (TTs) are vitamin E derivatives naturally occurring in several plants and vegetable oils. Like Tocopherols (TPs), they comprise four isoforms, α, β, γ and δ, but unlike TPs, they present an unsaturated isoprenoid chain. Recent studies indicate that TTs provide important health benefits, including neuroprotective, anti-inflammatory, anti-oxidant, cholesterol lowering and immunomodulatory effects. Moreover, they have been found to possess unique anti-cancer properties...

BACKGROUND: Esophageal Carcinoma (EC) is the eighth most common cancer worldwide. Numerous studies have highlighted a vital role of microRNAs (miRNAs) in the development of EC. However, the mechanism of microRNA (miRNA)-141 in Esophageal Squamous Cell Carcinoma (ESCC) remains unknown. OBJECTIVE: In this study, we explored the effects of miRNA-141 on EC cell proliferation, apoptosis, xenograft tumour growth and their possible mechanisms. METHODS: A lentivirus-vector-expressing miRNA-141 was constructed, and a TE-1 cell line of ESCC with a stable expression of miRNA-141 was transfected and screened...

BACKGROUND: Solid tumors often contain hypoxic microenvironments due to abnormal vasculatures and outweighing demands of oxygen. Cancer cells rely on anaerobic respiration, leading to sequential acidic microenvironments. Hypoxic and acidic microenvironments cause genetic instability and activate signaling pathways, contributing to cancer progression and drug therapy resistance, and have become targets for developing novel anti-cancer agents. OBJECTIVE: This article reviews recent advances in the development of novel anti-cancer drugs targeting hypoxic and acidic microenvironments...

Massive vessel recruitment is required to sustain rapid tumor growth by delivering oxygen and nutrients. Current strategies to counteract angiogenesis are mostly aimed at reducing tumor vessel density. However, many of these drugs have been shown to trigger hypoxia, thus exacerbating tumor aggressiveness. Promising results come from a completely different approach based on the "normalization" of the endothelial layer and the consequent improvement of the vascular function. Since endothelial metabolism has proved essential in the regulation of the angiogenic switch, many recent patents focus on agents able to inhibit specific metabolic pathways in tumor-associated endothelial cells (TECs) in order to provide vessel normalization...
