Hypoxia-regulated secretion of IL-12 enhances antitumor activity and safety of CD19 CAR-T cells in the treatment of DLBCL.

CD19-targeted chimeric antigen receptor-modified T (CD19 CAR-T) cell therapy has been demonstrated as one of the most promising therapeutic strategies for treating B cell malignancies. However, it has shown limited treatment efficacy for diffuse large B cell lymphoma (DLBCL). This is, in part, due to the tumor heterogeneity and the hostile tumor microenvironment.

Natural products targeting glycolysis in cancer.

Many energy metabolism pathways exist in cancer, including glycolysis, amino acid metabolism, fatty acid oxidation, and mitochondrial respiration. Tumor cells mainly generate energy through glycolysis to maintain growth and biosynthesis of tumor cells under aerobic conditions. Natural products regulate many steps in glycolysis and targeting glycolysis using natural products is a promising approach to cancer treatment.

The two-faced role of ATF2 on cisplatin response in gastric cancer depends on p53 context.

Background: Activating transcription factor-2 (ATF2) is a member of the basic leucine zipper family of DNA-binding proteins, which exhibits both oncogenic and tumor suppression activity in different tumors. However, the molecular mechanism of its dual function in cancer chemotherapy especially in gastric cancer has still not been elucidated.

Methods: The protein expression and location of ATF2 in gastric cancer tissues was detected with immunohistochemistry assay, and the clinical significance was analyzed using TCGA and GEO database.

Estrogen receptors participate in silibinin-caused nuclear translocation of apoptosis-inducing factor in human breast cancer MCF-7 cells.

Our previous studies showed that silibinin promoted activation of caspases to induce apoptosis in human breast cancer MCF-7 cells by down-regulating the protein expression level of estrogen receptor (ER) α and up-regulating ERβ. Recently, it has been reported that silibinin-induced apoptosis also involved nuclear translocation of apoptosis-inducing factor (AIF). Here we report that silibinin induces nuclear translocation of AIF through the down-regulation of ERα and up-regulation of ERβ in a concentration dependent manner in MCF-7 cells.

Chamaejasmin B Decreases Malignant Characteristics of Mouse Melanoma B16F0 and B16F10 Cells.

Chamaejasmin B (CHB), a natural biflavone isolated from L., has been reported to exhibit anti-cancer properties; however, its effect in melanoma cells is not clear. Here, we aimed to investigate the anticancer effect of CHB in mouse melanoma B16F0 and B16F10 cells.

Silibinin-induced mitochondria fission leads to mitophagy, which attenuates silibinin-induced apoptosis in MCF-7 and MDA-MB-231 cells.

We reported previously that higher doses (150-250 μM) of silibinin enhanced fission and inhibited fusion of mitochondria, accompanying apoptosis of double-positive breast cancer cell line MCF-7 cells and triple-negative breast cancer cell line MDA-MB-231 cells. We report here three important questions yet unclarified in the previous study; 1) Whether enhanced fission of mitochondria by the treatment of silibinin leads to mitophagy, 2) Whether mitophagy positively contributes to apoptosis and 3) Whether estrogen receptor-positive (ER) MCF-7 cells and estrogen receptor-negative (ER) MDA-MB-231 cells are affected in a different way by silibinin treatment, since silibinin often works through ERs signaling pathway. Mitophagy driven by Pink1/Parkin signaling, plays an important role in eliminating damaged mitochondria.

Silibinin inhibits migration and invasion of breast cancer MDA-MB-231 cells through induction of mitochondrial fusion.

Human triple negative breast cancer cells, MDA-MB-231, show typical epithelial to mesenchymal transition associated with cancer progression. Mitochondria play a major role in cancer progression, including metastasis. Changes in mitochondrial architecture affect cellular migration, autophagy and apoptosis.

Silibinin-induced apoptosis of breast cancer cells involves mitochondrial impairment.

Mitochondria are dynamically regulated by fission and fusion processes. Silibinin induces apoptosis of MCF-7 and MDA-MB-231 human breast cancer cells. However, whether or not mitochondria dysfunction is involved in the apoptosis induction with silibinin of both types of the cells remains unknown.

Low Dose of Acacetin Promotes Breast Cancer MCF-7 Cells Proliferation Through the Activation of ERK/ PI3K /AKT and Cyclin Signaling Pathway.

Background: Phytoestrogens have been proposed as replaceable medicines for climacteric hormone replacement therapy, on the basis of EP3138562 and US5516528. However, recent studies demonstrated that phytoestrogens might promote the proliferation of breast cancer cells, which is rooted in their estrogenic activity. Acacetin, as one phytoestrogen, has been reported to exhibit estrogenic activity.

Licochalcone D induces apoptosis and inhibits migration and invasion in human melanoma A375 cells.

The aim of the present study was to determine the effects of Licochalcone D (LD) on the apoptosis and migration and invasion in human melanoma A375 cells. Cell proliferation was determined by sulforhodamine B assay. Apoptosis was assessed by Hoechst 33258 and Annexin V‑FITC/PI staining and JC‑1 assay.

Alteronol induces cell cycle arrest and apoptosis via increased reactive oxygen species production in human breast cancer T47D cells.

Objective: Emerging evidence showed that alteronol has a potential antitumour effect in several tumour cells. However, the antitumour effect of alteronol on breast cancer has not been reported. This study investigated the mechanisms of alteronol-induced cell proliferation inhibition in human breast cancer T47D cells.

Isoliquiritigenin induces apoptosis of human bladder cancer T24 cells via a cyclin-dependent kinase-independent mechanism.

The aim of the present study was to investigate whether an increase in cyclin-dependent kinase 2 (CDK2) activity is involved in apoptosis of human bladder cancer T24 cells induced by isoliquiritigenin (ISL). The viability of T24 cells was estimated using a sulforhodamine B assay. Cell morphological changes were examined using Hoechst 33258 staining.

Potent effects of dioscin against pancreatic cancer via miR-149-3P-mediated inhibition of the Akt1 signalling pathway.

Background And Purpose: The aim of the present study was to investigate the effects and possible underlying mechanisms of dioscin against pancreatic cancer in vitro and in vivo.

Experimental Approach: In vitro actions of dioscin on viability of ASPC-1 and PANC-1 cells, and in vivo effects to suppress the tumour growth of cell xenografts in nude mice were assessed. In addition, microRNA microarray analysis determined which microRNAs were affected by dioscin.

Isoliquiritigenin Inhibits Proliferation and Induces Apoptosis via Alleviating Hypoxia and Reducing Glycolysis in Mouse Melanoma B16F10 Cells.

Background: Isoliquiritigenin (ISL) is a licorice chalcone. According to CN104758274, CN101658513 and US009089546, it is claimed that ISL has anti-inflammatory, anti-oxidative, and anti-tumoral effects.

Objective: This study aimed to investigate the potential therapeutic effect of ISL in mouse melanoma B16F10 cells.

Dioscin suppresses human laryngeal cancer cells growth via induction of cell-cycle arrest and MAPK-mediated mitochondrial-derived apoptosis and inhibition of tumor invasion.

The anti-cancer effects of dioscin have been widely reported. However, its effect on laryngeal cancer remains unknown. In the present paper, our results showed that dioscin markedly caused cell apoptosis and DNA damage, increased reactive oxygen species (ROS) level, induced S-phase arrest, and inhibited invasion of human laryngeal cancer HEp-2 and TU212 cells.
