Abstract
Over a century ago, the phenothiazine dye, methylene blue, was discovered to have both antipsychotic and anti-cancer effects. In the 20th-century, the first phenothiazine antipsychotic, chlorpromazine, was found to inhibit cancer. During the years of elucidating the pharmacology of the phenothiazines, reserpine, an antipsychotic with a long historical background, was likewise discovered to have anti-cancer properties. Research on the effects of antipsychotics on cancer continued slowly until the 21st century when efforts to repurpose antipsychotics for cancer treatment accelerated. This review examines the history of these developments, and identifies which antipsychotics might treat cancer, and which cancers might be treated by antipsychotics. The review also describes the molecular mechanisms through which antipsychotics may inhibit cancer. Although the overlap of molecular pathways between schizophrenia and cancer have been known or suspected for many years, no comprehensive review of the subject has appeared in the psychiatric literature to assess the significance of these similarities. This review fills that gap and discusses what, if any, significance the similarities have regarding the etiology of schizophrenia.

Abstract
We evaluated the preventive and therapeutic effects of aqueous suspensions of garlic, tomato, and garlic + tomato in the development of experimental Ehrlich tumors in mice. The aqueous suspensions (2%) were administered over a short term for 30 days before tumor inoculation and 12 days afterward, and suspensions at 6% were administered for 180 days before inoculation and for 12 days afterward. The volume, number, and characteristics of the tumor cells and AgNOR counts were determined to compare the different treatments. Aqueous 6% suspensions of garlic, tomato, and garlic + tomato given over the long term significantly reduced tumor growth but when given over the short term, they did not alter tumor growth.

Abstract
OBJECTIVES Sleep deprivation is a growing public health hazard, yet it is still under-recognized. Sleep disorders and disruption of sleep patterns may compromise the immune function and adversely affect host resistance to infectious diseases. This is a particular risk in cancer patients, who report a high frequency of sleep disturbances. The present study investigated the effects of sleep deprivation on the development of Ehrlich ascitic tumors (EAT) in female BALB/c mice. Our study also evaluated whether EAT would induce alterations in sleep pattern. Spleen lymphocyte cell populations and mortality were also quantified. METHODS Female BALB/c mice were intraperitoneally inoculated with EAT cells. Immediately after the inoculation procedure, animals were sleep deprived for 72 h. Ten or 15 days after inoculation, the number of tumoral cells was quantified and the lymphocytic cell population in the spleen was characterized by flow cytometry. In addition, the effect of sleep deprivation on EAT-induced mortality was quantified and the influence of EAT on sleep patterns was determined. RESULTS Sleep deprivation did not potentiate EAT growth, but it significantly increased mortality. Additionally, both EAT and sleep deprivation decreased frequencies of splenic CD4+, CD8+ and CD19+ cells. With respect to sleep patterns, EAT significantly enhanced paradoxical sleep time. CONCLUSIONS Although sleep deprivation did not potentiate EAT growth, it decreased the survival of female tumor-bearing mice.

Translocator protein (18 kDa) mediates the pro-growth effects of diazepam on Ehrlich tumor cells in vivo. Eur J Pharmacol 2009; 626:131-8. [PMID: 19782064 DOI: 10.1016/j.ejphar.2009.09.036] [Citation(s) in RCA: 22] [Impact Index Per Article: 1.5] [Reference Citation Analysis] [Abstract] [Track Full Text] [Journal Information] [Subscribe] [Scholar Register] [Received: 03/24/2009] [Revised: 08/18/2009] [Accepted: 09/08/2009] [Indexed: 01/31/2023]
Abstract
The Translocator Protein (TSPO), previously known as the peripheral-type benzodiazepine receptor, is a ubiquitous drug- and cholesterol-binding protein that is up regulated in several types of cancer cells. TSPO drug ligands (e.g., diazepam) induce or inhibit tumor cell proliferation, depending on the dose and tissue origin. We have previously shown that TSPO is expressed in Ehrlich tumor cells and that diazepam increases proliferation of these cells in vitro. Here, we investigated the in vivo effects of diazepam on Ehrlich tumor growth and the role of TSPO in mediating this process. Oral administration of diazepam to mice (3.0mg/kg/day for 7 days) produced plasma and ascitic fluid drug concentrations of 83.83 and 54.12 nM, respectively. Diazepam increased Ehrlich tumor growth, likely due to its ability to increase tumor cell proliferation and Reactive Oxygen Species production. Radioligand binding assays and nucleotide sequencing revealed that Ehrlich tumor cell TSPO had the same pharmacological and biochemical properties as TSPO described in other tumor cells. The estimated K(d) for PK 11195 in Ehrlich tumor cells was 0.44 nM and 8.70 nM (low and high binding site, respectively). Structurally diverse TSPO drug ligands with exclusive affinity for TSPO (i.e., 4-chlordiazepam, Ro5-4864, and isoquinoline-carboxamide PK 11195) also increased Ehrlich tumor growth. However, clonazepam, a GABA(A)-specific ligand with no affinity for TSPO, failed to do so. Taken together, these data suggest that diazepam induces in vivo Ehrlich tumor growth in a TSPO-dependent manner.

Abstract
The aim of this study was to investigate the effect of chronic treatment with C. multijuga oil on Ehrlich tumor evolution. C. multijuga was fractionated in a KOH impregnated silica gel column chromatography to give three distinct fractions, i.e., hexanic, chloroformic, and methanolic, mainly composed by hydrocarbon sesquiterpenes, oxygenated sesquiterpenes and acidic diterpenes, respectively. Results demonstrated that the C. multijuga oil, the hexanic, and chloroformic fractions did not develop toxic effects. The oil, hexanic and chloroformic fractions (doses varying between 100 and 200mg/kg) showed antineoplasic properties against Ehrlich ascitic tumor (EAT) and solid tumor during 10 consecutive days of treatment inhibiting ascitic tumor cell number, reverting medulla and blood cell counts to values similar to control group, and inhibiting the increase on several inflammatory mediators (total protein, PGE(2), nitric oxide, and TNF) on ascitic fluid. The treatment also inhibited the increase in paw volume on tumor-inoculated mice. In conclusion, C. multijuga as well as its fractions demonstrated antineoplasic effect even after oral administration confirming its use by traditional medicine.

Abstract
The leaves and the oil from the seeds of Chenopodium ambrosioides L. (Chenopodiaceae), a plant known in Brazil as 'mastruz', have been used by native people to treat parasitic diseases. Experimentally it was shown that Chenopodium ambrosioides inhibits the Ehrlich tumor growth, what could be due to an immunomodulatory effect of this product. The aim of this study was to investigate the effect of hydroalcoholic crude extract (HCE) from leaves of Chenopodium ambrosioides on macrophage activity and on lymphoid organs cellularity. C3H/HePas mice received the HCE (5mg/kg) by intraperitoneal via and were sacrificed 2 days later. HCE treatment did not alter the cell number in bone marrow, but it increased the cell number in peritoneal cavity, spleen and lymph node. The spreading and phagocytosis activity, the PMA-induced hydrogen peroxide (H(2)O(2)) release and the nitric oxide (NO) production were also increased when compared to control group. Similar results were obtained with concanavalin A (Con A), used as a positive control, with exception of the NO production that was only detected in HCE-derived macrophages. The in vitro treatment with HCE induced a dose-dependent NO production by resident macrophages, but did not enhance the NO production by HCE-derived macrophage, which however, was enhanced by Con A, suggesting that HCE and Con A induce NO production by different routes. In conclusion, HCE-treatment was able to increase the macrophages activity and also the cellular recruitment to secondary lymphoid organs, what could explain the previously related anti-tumor activity of Chenopodium ambrosioides.

Abstract
The leaves of Chenopodium ambrosioides L. [Chenopodiaceae] ('mastruz') have been indicated for the treatment of several diseases, among which the cancer. There are no results focusing the effect of C. ambrosioides treatment on tumor development in vivo. The aim of this study was to investigate the effect of treatment with C. ambrosioides on Ehrlich tumor development. Swiss mice were treated by intraperitoneal route (i.p.) with hydroalcoholic extract from leaves of C. ambrosioides (5 mg/kg) or with PBS (control group) 48 h before or 48 h later the Ehrlich tumor implantation. The tumor cells were implanted on the left footpad (solid tumor) or in the peritoneal cavity (ascitic tumor). To determine the solid tumor growth, footpad was measured each 2 days until the fourteenth day, when the feet were weighed. Ascitic tumor development was evaluated after 8 days of tumor implantation by quantification of the ascitic fluid volume and tumor cell number. The i.p. administration of C. ambrosioides extract before or after the tumor implantation significantly inhibited the solid and ascitic Ehrlich tumor forms. This inhibition was observed in ascitic tumor cell number, in the ascitic volume, in the tumor-bearing foot size and foot weight when compared to control mice. The treatments also increased the survival of tumor-bearing mice. In conclusion, C. ambrosioides has a potent anti-tumoral effect which was evident with a small dose and even when the treatment was given two days after the tumor implantation. This effect is probably related with anti-oxidant properties of C. ambrosioides.

Abstract
Haloperidol is a receptor D2 antagonist frequently used in the treatment of schizophrenic patients. Haloperidol increased prolactin release from anterior pituitary gland, and prolactin modulates immune system activity. Groups of six male and female rats received an acute 2 mg/kg haloperidol treatment (E1), or a long-term (E2) haloperidol treatments (2 mg/kg/day for 21 days); control rats were treated similarly, but with control solution (groups C1 and C2, respectively). In this work long-term haloperidol treatment (E2) increased macrophage spreading, phagocytosis and NO release in male and female rats. However, acute haloperidol treatment (E1) did not change macrophage activity. Corticosterone and prolactin serum levels were increased after acute (E1) and long-term (E2) haloperidol treatments in male and female rats, being this increment higher in female. Macrophage of male and female rats presented the same pattern of alterations after acute and long-term haloperidol treatments. Haloperidol-induced macrophage activation was discussed in the light of a possible indirect effect through prolactin increments in rats, or, alternatively, as a consequence of a direct action of macrophage dopamine receptor.

Abstract
Subcutaneous treatment with haloperidol (2.0 mg/kg) was found to increase both the percent of macrophage spreading and nitric oxide (NO) release in peritoneal macrophage from animals inoculated intraperitoneally with 5.0 x 10(6) Ehrlich ascites cells. This haloperidol-induced macrophage activation seems to be involved in its antitumoral effect since cotreatment with the iNOS inhibitor aminoguanidine was able to reverse the inhibitory effect of haloperidol on the development of the Ehrlich solid carcinoma.
