Neoplastic process may cause distinct changes in the morphology, i.e. size and number of the neurons of the neuronal plexuses forming the enteric nervous system (ENS) of the human intestine. Moreover, it was also reported that these changes were not directly associated with apoptosis. Thus, the main aim of this study was to determine the atrophic changes of myenteric plexuses (MPs) in the vicinity of cancer invasion and the potential reason which may be responsible for these changes if they occur. Tissue samples from the stomach were collected from ten patients which undergo organ resection due to cancer diagnosis...

The present study evaluated the protective effect of the natural compound flavonoids of Rosa roxburghii Tratt (FRT) against γ-radiation-induced apoptosis and inflammation in mouse thymus cells in vivo and in vitro. Thymus cells and mice were exposed to 60 Co γ-ray at a dose of 6 Gy. The radiation treatment induced significant cell apoptosis and inflammation. Radiation increased the expressions of cleaved caspase 3/8-10, AIF, and PARP-1, and FRT could mitigate their activation and inhibit subsequent apoptosis in the thymus both in vitro or in vivo...

Microvesicles (MVs) have been shown to be involved in pathophysiology of ischemic heart diseases. However, the underlying mechanisms are still unclear. Here we investigated the effects of MVs derived from ischemic preconditioning (IPC-MVs) on myocardial ischemic/reperfusion (I/R) injury in rats. Myocardial IPC model was elicited by three cycles of ischemia and reperfusion of the left anterior descending (LAD) coronary artery. IPC-MVs from the peripheral blood of the above animal model were isolated by ultracentrifugation and characterized by flow cytometry and transmission electron microscopy...

Apoptotic volume decrease (AVD) is a characteristic cell shrinkage observed during apoptosis. There are at least two known processes that may result in the AVD: exit of intracellular water and splitting of cells into smaller fragments. Although AVD has traditionally been attributed to water loss, direct evidence for that is often lacking. In this study, we quantified intracellular water in staurosporine-treated cells using a previously described optical microscopic technique that combines volume measurements with quantitative phase analysis...

Natamycin, a Food and Drug Administration approved anti-fungal drug, and also used as a food additive was evaluated for anti-leishmanial activity since it is known to specifically bind to ergosterol, which is essential to these parasites but absent in mammals. Promising anti-proliferative activity was observed in both promastigote and amastigote forms of the parasite with IC50 values of 15 and 8 µM respectively and a selective index of 12.5. The ultrastructural effects of natamycin on both forms of the parasite and physiological effects on promastigotes were studied in detail for the first time...

The over-expressions of brain-derived neurotrophic factor (BDNF) and its tyrosine kinase receptor TrkB have been reported to induce chemo-resistance in neuroblastoma (NB) cells. In this study, we investigated the roles of P53 and BCL2 family members in the protection of BDNF/TrkB from etoposide-induced NB cell death. TB3 and TB8, two tetracycline (TET)-regulated TrkB-expressing NB cell lines, were utilized. The expressions of P53 and BCL2 family members were detected by Western blot or RT-PCR. Transfection of siRNAs was used to knockdown P53 or PUMA...

Cardiomyocyte apoptosis has been observed in several cardiovascular diseases and contributes to the subsequent cardiac remodeling processes and progression to heart failure. Consequently, apoptosis imaging is helpful for noninvasively detecting the disease progression and providing treatment guidance. Here, we tested 18 F-labeled 2-(5-fluoropentyl)-2-methyl-malonic acid (18 F-ML-10) and 18 F-labeled 2-(3-fluoropropyl)-2-methyl-malonic acid (18 F-ML-8) for apoptosis imaging in rat models of myocardial infarction (MI) and compared them with 18 F-fluorodeoxyglucose (18 F-FDG)...

In the early stage of acute pancreatitis (AP), abundant cytokines induced by local pancreatic inflammation enter the bloodstream, further cause systemic inflammatory response syndrome (SIRS) by "trigger effect", which eventually leads to multiple organ dysfunction syndrome (MODS). During SIRS and MODS, the intestinal barrier function was seriously damaged accompanied by the occurrence of gut-derived infection which forms a "second hit summit" by inflammatory overabundance. Gastrointestinal microecology, namely the biologic barrier, could be transformed into a pathogenic state, which is called microflora dysbiosis when interfered by the inflammatory stress during AP...

Prostate cancer (PCa) is an incurable disease at the metastatic stage. Although there are different options for treatment, the results are limited. MicroRNAs (miRNAs) are a group of small, noncoding, regulatory RNAs with important roles in regulating gene expression. miR-145 is reported to be a key tumor suppressor miRNA (tsmiR) that controls important oncogenes, such as MYC and RAS. In this study, in vitro studies were performed to show the control of MYC and RAS by miR-145. Flow cytometry was used to analyze cell proliferation and apoptosis...

The Erythropoietin-producing human hepatocellular carcinoma (Eph) receptors constitute the largest family of receptor tyrosine kinases and interact with a group of ligands called Ephrins. An essential feature of the Eph receptors and Ephrin ligands is that both are membrane-bound and, upon cell-cell interaction, initiate a bidirectional signaling involving both the receptor (forward signaling) and the ligand (reverse signaling). They regulate a large set of pleiotropic functions in virtually every tissue and physiological system...

Resveratrol, a naturally occurring polyphenolic antioxidant, is a potential chemoprophylactic agent for various cancers, including colorectal cancer. Although emerging evidence continually suggests that a number of resveratrol derivatives may be better cancer chemopreventive candidates than resveratrol, studies on the mechanism of action of these derivatives are limited. This is the first study which investigates the mechanism underlying the cytotoxic effect of a synthesized resveratrol analogue, (E)-N-(2-(4-methoxystyryl) phenyl) furan-2-carboxamide (CS) on colorectal cancer...

Pancreatic adenocarcinoma (PDAC) is a highly aggressive cancer with a high chance of recurrence, limited treatment options, and poor prognosis. A recent study has classified pancreatic cancers into four molecular subtypes: (1) squamous, (2) immunogenic, (3) pancreatic progenitor and (4) aberrantly differentiated endocrine exocrine. Among all the subtypes, the squamous subtype has the worst prognosis. This study aims to utilize large scale genomic datasets and computational systems biology to identify potential drugs targeting the squamous subtype of PDAC through combination therapy...

Recent studies have confirmed that IL-6/GP130 targets are closely associated with tumor growth, metastasis and drug resistance. 5-Fluorouracil (5-FU) is the most common chemotherapeutic agent for colon cancer but is limited due to chemoresistance and high cytotoxicity. Bazedoxifene (BZA), a third-generation selective estrogen receptor modulator, was discovered by multiple ligand simultaneous docking and drug repositioning approaches to have a novel function as an IL-6/GP130 target inhibitor. Thus, we speculated that in colon cancer, the anti-tumor efficacy of 5-FU might be increased in combination with IL-6/GP130 inhibitors...

Prodigiosin, a secondary metabolite isolated from marine Vibrio sp., has antimicrobial and anticancer properties. This study investigated the cell death mechanism of prodigiosin in glioblastoma. Glioblastoma multiforme (GBM) is an aggressive primary cancer of the central nervous system. Despite treatment, or standard therapy, the median survival of glioblastoma patients is about 14.6 month. The results of the present study clearly showed that prodigiosin significantly reduced the cell viability and neurosphere formation ability of U87MG and GBM8401 human glioblastoma cell lines...

The aim of this study was to investigate whether RIPK1 mediated mitochondrial dysfunction and oxidative stress contributed to compression-induced nucleus pulposus (NP) cells necroptosis and apoptosis, together with the interplay relationship between necroptosis and apoptosis in vitro. Rat NP cells underwent various periods of 1.0 MPa compression. To determine whether compression affected mitochondrial function, we evaluated the mitochondrial membrane potential, mitochondrial permeability transition pore (mPTP), mitochondrial ultrastructure and ATP content...

This study was to explore the feasibility of prediction and classification of cells in different stages of apoptosis with a stain-free method based on diffraction images and supervised machine learning. Apoptosis was induced in human chronic myelogenous leukemia K562 cells by cis-platinum (DDP). A newly developed technique of polarization diffraction imaging flow cytometry (p-DIFC) was performed to acquire diffraction images of the cells in three different statuses (viable, early apoptotic and late apoptotic/necrotic) after cell separation through fluorescence activated cell sorting with Annexin V-PE and SYTOX® Green double staining...

As an evolutionarily conserved serine/threonine kinase of the phosphoinositide 3-kinase (PI3K) related kinase family, the mechanistic/mammalian target of rapamycin (mTOR) plays vital roles in the PI3K/AKT/mTOR pathway, participating in different cellular processes including cell survival, metabolism and proliferation. Aberrant activity of this signaling pathway may lead to oncogenesis. Over the last two decades, great progress has been made in the understanding of mTOR activation and how its response is counteracted for maintaining tissue homeostasis...
