Synthesis and anti-melanoma effect of 3-O-prenyl glycyrrhetinic acid against B16F10 cells via induction of endoplasmic reticulum stress-mediated autophagy through ERK/AKT signaling pathway
In this study, 4-phenylbutyric acid (4PBA, a chemical chaperone) and small interference RNA (siRNA) knockdown of C/EBP Homologous Protein (CHOP)/growth arrest- and DNA damage-inducible gene 153(GAD153) blocked NPC-402-mediated autophagy induction, thus confirming the role of ER stress and autophagy in melanoma cell death. NPC-402 induced oxidative stress and apoptosis in melanoma cells, which were effectively mitigated by treatment with N-acetylcysteine (NAC). In vivo studies showed that intraperitoneal (i.p.) injection of NPC-402 at 10 mg/kg (5 days in 1 week) significantly retarded angiogenesis in the Matrigel plug assay...

Auriculasin enhances ROS generation to regulate colorectal cancer cell apoptosis, ferroptosis, oxeiptosis, invasion and colony formation
Biochem Biophys Res Commun. 2021 Dec 1;587:99-106. doi: 10.1016/j.bbrc.2021.11.101. Online ahead of print.ABSTRACTColorectal cancer (CRC) is one of the most common malignant tumors in the digestive system, and Chinese herbal medicine plays an important role in tumor treatment. The in-depth study of auriculasin isolated from Flemingia philippinensis showed that auriculasin promoted reactive oxygen species (ROS) generation in a concentration-dependent manner; when ROS scavenger NAC was added, the effects of auriculasin in promoting ROS generation and inhibiting cell viability were blocked. Auriculasin induced CRC cell apopto...

Apoptosis in Cancer Cells Is Induced by Alternative Splicing of hnRNPA2/B1 Through Splicing of Bcl-x, a Mechanism that Can Be Stimulated by an Extract of the South African Medicinal Plant, Cotyledon orbiculata
Alternative splicing is deregulated in cancer and alternatively spliced products can be linked to cancer hallmarks. Targeting alternative splicing could offer novel effective cancer treatments. We investigated the effects of the crude extract of a South African medicinal plant, Cotyledon orbiculata, on cell survival of colon (HCT116) and esophageal (OE33 and KYSE70) cancer cell lines. Using RNASeq, we discovered that the extract interfered with mRNA regulatory pathways. The extract caused hnRNPA2B1 to splice from the hnRNPB1 to the hnRNPA2 isoform, resulting in a switch in the BCL2L1 gene from Bcl-xL to Bcl-xS causing acti...

Ophiopogonin B induces apoptosis, mitotic catastrophe and autophagy in A549 cells.
Abstract Ophiopogonin B (OP-B), a saponin compound isolated from Radix Ophiopogon japonicus, was verified to inhibit cell proliferation in numerous non-small cell lung cancer (NSCLC) cells in our previous study. However, the precise mechanisms of action have remained unclear. In the present study, we mainly investigated the effects of OP-B on adenocarcinoma A549 cells to further elaborate the underlying mechanisms of OP-B in different NSCLC cell lines. Detection by high content screening (HCS) and TUNEL assay verified that OP-B induced apoptosis in this cell line, while detection of Caspase-3, Bcl-2 and Bax showed...

Tanshinones suppress AURKA through up-regulation of miR-32 expression in non-small cell lung cancer.
Authors: Ma ZL, Zhang BJ, Wang DT, Li X, Wei JL, Zhao BT, Jin Y, Li YL, Jin YX Abstract Tanshinone is the liposoluble constituent of Salia miltiorrhiza, a root used in traditional herbal medicine which is known to possess certain health benefits. Although it is known that tanshinones, including tanshinone I (T1), tanshinone IIA (T2A), and cryptotanshinone (CT), can inhibit the growth of lung cancer cells in vitro, the mechanism under which they act is still unclear. AURKA, an oncogene, encodes a serine-threonine kinase which regulates mitotic processes in mammalian cells. Here, we reported that tanshinones mediate ...

Abstract 2335: Thymoquinone induces the MUC4 mRNA-destabilizing activity of Tristetraprolin
In this study, we investigate that Tymoquinone (TQ) which is an active ingredient derived from the medicinal plant Nigella satia induces the TTP mRNA and protein expression in AGS and MDA-MB231. TQ treatment destabilized a luciferase mRNA containing cIAP2, VEGF and MUC4 ARE. Transfected cells were treated with various kinds of MAPK inhibitors, treatment with Sorafenib (RAF inhibitor) and U0126 (MEK-1/2) reduced the TTP induction activity of TQ in a dose-dependent manner. We confirmed that co-treatment with sorafenib/U0126 and TQ also reduced TTP expression. Following TQ downregulated the expression of MUC4 in previous stud...

Involvement of C/EBPβ in monocytic differentiation of acute myeloid leukemia cells induced by LW-218, a new synthesized flavonoid.
In this study, we found that LW-218, a new synthesized flavonoid, inhibited proliferation and induced differentiation of acute myeloid leukemia cells. The IC50s of LW-218 in HL-60, U937, K562, and NB4 cell lines were all less than 5 μM, suggesting greater capacity than compounds we have reported. LW-218 induced differentiation effects including morphologic changes, NBT reduction, and both of CD11b and CD14 expression. Results of western blots and siRNA transfection revealed that LW-218 increased the LAP/LIP ratio of C/EBPβ which regulated monocytic differentiation of leukemia cells. Meanwhile, these differentiation eff...
