Papaverine-induced changes in physiological characters of Ehrlich ascites tumor cell membranes.

Only registered users can translate articles

Physiological characters of Ehrlich ascites tumor cell membranes were altered by papaverine. The agent induced changes in membrane potential as monitored by cyanine dye (diS-C3-(5)) technique. Papaverine also strongly inhibited increase in membrane permeability to K+ ion induced by lysolecithin. In

Cell cycle arrest and apoptogenic properties of opium alkaloids noscapine and papaverine on breast cancer stem cells.

Only registered users can translate articles

Previous report of the vast effectiveness of opium derivatives in cancer therapy is leading us to see possible effects of these derivatives on cancer stem cells in order to find new agent for cancer therapy. In this study, cells were stained for CSC markers and sorted by magnetic beads. CSCs exhibit

The effect of papaverine on morphologic differentiation, proliferation and invasive potential of human prostatic cancer LNCaP cells.

Only registered users can translate articles

BACKGROUND Intracellular cyclic adenosine monophosphate (AMP) level changes are thought to play an important role in inhibiting cell proliferation and inducing differentiation in several types of cells. It has been reported that cyclic AMP analogs induce terminal differentiation in human prostate

Papaverine selectively inhibits human prostate cancer cell (PC-3) growth by inducing mitochondrial mediated apoptosis, cell cycle arrest and downregulation of NF-κB/PI3K/Akt signalling pathway.

OBJECTIVE The main objective of the current research work was to investigate the antitumor effects of papaverine in PC-3 human prostate cancer cells along with testing its toxicity in the normal human fibroblast (NHF) cells. METHODS The cytotoxic effects of papaverine were examined by the MTT cell

Ubiquinol and the papaverine derivative caroverine prevent the expression of tumour- promoting factors in adenoma and carcinoma colon cancer cells induced by dietary fat.

Only registered users can translate articles

High consumption of dietary fat promotes colon carcinogenesis. While this effect is well known the underlying mechanism is not understood. Fatty acid hydroperoxides (LOOH) arise from unsaturated fatty acids in the presence of oxygen and elevated temperature during food processing. An approach was

High-Throughput Screening Identified Compounds Sensitizing Tumor Cells to Glucose Starvation in Culture and VEGF Inhibitors In Vivo.

Only registered users can translate articles

Tumor cells utilize glucose to fuel their anabolic needs, including rapid proliferation. However, due to defective vasculature and increased glucose uptake, tumor cells must overcome glucose deprivation. Accordingly, tumor cells depend on cellular pathways promoting survival under such conditions.

Papaverine Has Therapeutic Potential for Sepsis-Induced Neuropathy in Rats, Possibly via the Modulation of HMGB1-RAGE Axis and Its Antioxidant Prosperities

Only registered users can translate articles

Aim: Our aim was to investigate the possible neuroprotective properties of papaverine in sepsis-induced critical illness neuropathy (SCIN) through the evaluation of various inflammatory biochemical markers, including interleukin 6 (IL-6),

Deuterium MR spectroscopy at 4.7 T. Quantification of tumour and subcutaneous tissue blood flow in animal models.

Only registered users can translate articles

Deuterium MR spectroscopy was used for the determination of tissue blood flow (TBF). The tracer D2O was injected into the tissue of interest, and tracer washout was followed using a 4.7 T spectroscopy/imaging unit. Normal subcutaneous tissue in rats was studied, as well as tissue influenced by

Synergistic effect of hyperthermia, papaverine, and chemotherapy in murine neuroblastoma.

Only registered users can translate articles

The effects of microwave induced hyperthermia, papaverine, and chemotherapy were evaluated in transplanted CI300 murine neuroblastoma. One hundred forty-five Ajax mice received axillary subcutaneous implants of CI300 round cell neuroblastoma (1.25 X 10(6) cells). Animals were divided into 8

[Effect of cycloheximide, 2,4-dinitrophenol and papaverine on ribosomal RNA synthesis in Ehrlich ascitic carcinoma cells].

Only registered users can translate articles

The influence of 2,4-dinitrophenol (DNP), papaverine and cycloheximide on RNA synthesis in Ehrlich ascites tumour cells has been investigated. All above mentioned agents inhibit selectively synthesis of high-molecular rRNA precursor, when the cell population density is 3.10(7)--5.10(7) per 1 ml of

Murine tumor-induced platelet aggregation and coagulation: mechanisms, inhibitors, and species differences.

Only registered users can translate articles

This study examined the platelet-aggregating and procoagulant activities of two hematogenously disseminating tumors, a mouse lymphoblastic leukemia (L5178Y) and a mouse renal adenocarcinoma (RAG). Tumor-induced human platelet aggregation was inhibited by addition of the following agents to

[Sexual dysfunction following radical operation for cancer of the rectum and colon].

Only registered users can translate articles

Sexual dysfunction frequently occurs following radical operation for cancer of intrapelvic organs. However, the number of impotent patients with colon and rectal cancer who actually visited our Reproduction Center complaining of impotence after operation accounted for only 31 (1.8%) out of the 1,686

Morpho-physiological heterogeneity of cells within two rat prostate carcinoma cell lines AT-2 and MAT-LyLu differing in the degree of malignancy observed by cell cloning and the effects of caffeine, theophylline and papaverine upon a proportion of the clones.

Only registered users can translate articles

Analysis of the heterogeneity of clones of single cells from two established lines of the Dunning series of rat prostate carcinoma differing in the degree of malignancy, AT-2 (moderately malignant) and MAT-LyLu (highly malignant), was conducted. The results showed that not only the original tumors

Inhibitory effects of herbal alkaloids on the tumor necrosis factor-α and nitric oxide production in lipopolysaccharide-stimulated RAW264 macrophages.

Only registered users can translate articles

It is beneficial to treat chronic inflammatory condition in patients through diets that inhibit the production of proinflammatory cytokines and mediators such as tumor necrosis factor-α (TNF-α) and nitric oxide (NO). Since less attention has been paid to alkaloids in the diets than to polyphenols in

Influence of vasoactive drugs on local tumor blood flow.

Only registered users can translate articles

The influence of vasoactive drugs, including noradrenaline, isoprenaline and papaverine, on the local blood flow of a transplantable rat sarcoma and of normal subcutaneous tissue of the rat was studied by local [133 xenon] clearance technique. The microvascular bed of the tumour was studied by
