Berberine, is a plant alkaloid, proved to have anticancer effect on various cancers. Theophylline (TH), a natural product, is widely used in the treatment of respiratory difficulties. The present study designed to elucidate the effects of theophylline and berberine combination on breast cancer cells cytotoxicity, gene expression and cell cycle. MTT assay revealed that berberine inhibited MDA-MB-231 breast cancer cells viability in a time and dose dependent manner (IC50 of 100 μM) but theophylline had no considerably effect on the cells...

Agaricus bisporus is one of the most important edible and medicinal mushrooms in the world. It has been well known that Agaricus bisporus has an immunoregulatory role, but its active ingredients have not been completely identified. In this study, a glucogalactomannan named TJ3 was isolated and purified from Agaricus bisporus. TJ3 (827 kDa) is composed of mannose, galactose, glucose and xylose in the ratio 28.26 : 27.82 : 20.88 : 9.87 mainly joined by β-linkages. Functional analysis of TJ3 revealed that it effectively induced apoptosis in RAW 264...

Sepsis is characterized by injury of pulmonary microvascular endothelial cells (PMVEC) leading to barrier dysfunction. Multiple mechanisms promote septic PMVEC barrier dysfunction, including interaction with circulating leukocytes and PMVEC apoptotic death. Our previous work demonstrated a strong correlation between septic neutrophil (PMN)-dependent PMVEC apoptosis and pulmonary microvascular albumin leak in septic mice in vivo ; however, this remains uncertain in human PMVEC. Thus, we hypothesize that human PMVEC apoptosis is required for loss of PMVEC barrier function under septic conditions in vitro ...

Neonatal systemic inflammatory response and multiple organ dysfunction syndrome are the main postnatal insults influencing mortality and morbidity. Critically ill newborns with high predicted mortality are supported by extracorporeal membrane oxygenation (ECMO). Biomarkers of inflammatory response and endothelial injury can be used for early diagnosis and treatment of critical neonatal situations. The aim of our study was to explore plasma proteins and endothelial microvesicles as markers of inflammation and endothelial activation in newborns on ECMO and to compare them with healthy neonates...

Macrophage apoptosis exerts an efficient mechanism in controlling intracellular infection during innate immune response against various pathogens including malaria parasites. This study was carried out to determine the apoptosis activity in mouse macrophage cell line J774A.1 infected with a Mycobacterium bovis bacille Calmette-Guerin (BCG) clone and a recombinant BCG clone expressing the C-terminus of merozoite surface protein-1 (BCG-MSP1C) of Plasmodium falciparum for 48 h. In this study, a parent BCG cells was used as a control...

Glucocorticoids (GCs) are widely used to treat chronic diseases. Prolonged and/or overdose administration of GCs has many side-effects to human health including GC-induced osteoporosis (GIOP). In this investigation, the objective was to assess the influence that echinacoside (ECH) exerts upon dexamethasone-treated murine osteoblastic MC3T3-E1 cells. We found that ECH (5, 10, 20 and 40 mg/l) inhibited dexamethasone (1,000 nM)-suppressed cell viability as demonstrated by Cell Counting Kit-8 (CCK-8) assay. The dose of 10 mg/l was selected for the following experiments because this dose had a better effect than the dose of 5 mg/l, and the doses >10 mg/l had a similar effect as this dose...

Irisin is a newly discovered myokine which can relieve metabolic disorders and resist atherosclerosis. The effects of irisin on ox-LDL-induced macrophage apoptosis and endoplasmic reticulum stress-related pathways were observed in vitro . RAW264.7 macrophages were cultured in vitro and pretreated with irisin at 20, 40 and 80 ng/ml for 30 min, followed by culture with 100 mg/L ox-LDL and 5 mg/L tunicamycin (TM) for 12 h. The cell viability and apoptosis were detected by MTT assay and annexin V-FITC double staining...

The hedgehog-smoothened (HH/SMO) pathway has been proposed as a potential therapeutic target for hematological malignancies. Our previous studies designed a series of HH inhibitors with novel scaffolds distinctive from vismodegib, the first Food and Drug Administration-approved HH inhibitor for the treatment of basal-cell carcinoma and medulloblastoma. In the present study, we evaluated these HH inhibitors against blood cancers and found that HH78 displayed potent activity in suppressing the HH signaling pathway...

Immune thrombocytopenia (ITP) is the main pathogenesis of excessive platelet destruction and abnormal megakaryocyte apoptosis, however, the mechanism underlying this abnormality in megakaryocytes remains to be elucidated. Since autophagy and apoptosis are closely interrelated, it can be speculated that the abnormal apoptosis of ITP megakaryocytes is associated with autophagy. To test this hypothesis, a total of 14 patients with ITP and 23 healthy controls were recruited. MEG‑01 cell line was cultured in vitro, and morphological changes were observed by light microscopy, apoptosis was evaluated by flow cytometric analysis of Annexin V‑FITC/propidium iodide staining and western blot analysis of B‑cell lymphoma (Bcl)‑2, Bcl‑associated X protein (Bax), Beclin‑1 and cleaved caspase 3...

Ovarian cancer is one of the most common causes of female mortalities from gynecological tumors. An ent‑kaurane diterpenoid compound CRT1 (ent‑18‑acetoxy‑7β‑hydroxy kaur‑15‑oxo‑16‑ene), mainly isolated from the Vietnamese herb Croton tonkinesis has been used in folk medicine in Vietnam for cancer treatment. However, the effect of this compound on human ovarian cancer cells has not yet been reported. The objective of the present study was to determine the effect of CRT1 on the cell viability, apoptosis and metastasis of SKOV3 human ovarian cancer cells using a Cell Counting Kit‑8 assay, flow cytometric analysis of Annexin V‑fluorescein isothiocyanate/propidium iodide staining, western blot analysis, soft agar colony forming assay, wound healing assay and Matrigel invasion assay...

Ursolic acid (UA), is a kind of triterpene acid that exhibits wide biological properties. In this article, the effects of UA on apoptosis and the proliferation of human hepatoma Huh-7 cells were reported. The MTT results showed that cell viability of Huh-7 was reduced in a concentration and time-dependent effect. In addition, DAPI staining was used to detected condensation of chromatin in nucleus. Apoptotic cell population was examined using Annexin V/PI staining. The results showed that exposure to UA affected extrinsic and intrinsic pathways through, reduced expression of Bcl-2, Mcl-1, and TCTP; increased levels of the apoptotic proteins TNF-α, Fas, FADD, and Bax; and activation of cleaved caspase-3 and PARP...

Soluble guanylyl cyclase (sGC, EC is a key enzyme in the regulation of vascular tone. In view of the therapeutic interest of the NO/cGMP pathway, drugs were developed that either increase the NO sensitivity of the enzyme or activate heme-free apo-sGC. However, modulation of sGC activity by endogenous agents is poorly understood. In the present study we show that the maximal activity of NO-stimulated purified sGC is significantly increased by cytosolic preparations of porcine coronary arteries. Purification of the active principle by several chromatographic steps resulted in a protein mixture consisting of 100, 70, and 40 kDa bands on SDS polyacrylamide gel electrophoresis...

Ginger (Zingiber officinale Roscoe), a monocotyledonous herb, is widely used as an herbal medicine owing to the phytoconstituents it possesses. In the current study, the quantity of [6]-gingerol, the major phenolic ketone, in the fresh ginger and dried ginger rhizome was found to be 6.11 µg/mg and 0.407 µg/mg. Furthermore, [6]-gingerol was assessed for its antiapoptotic effects in human gastric adenocarcinoma (AGS) cells evidenced by acridine orange/ethidium bromide staining technique and Annexin-V assay...
