Novel and alternative options are being adopted to combat the initiation and progression of human cancers. One of the approaches is the use of molecules isolated from traditional medicinal herbs, edible dietary plants and seeds that play a pivotal role in the prevention/treatment of cancer, either alone or in combination with existing chemotherapeutic agents. Compounds that modulate these oncogenic processes are potential candidates for cancer therapy and may eventually make it to clinical applications. Diosgenin is a naturally occurring steroidal sapogenin and is one of the major bioactive compounds found in dietary fenugreek ( Trigonella foenum-graecum ) seeds...

A deficiency of maternal folic acid (FA) can compromise the function and development of the brain, and may produce a susceptibility to diseases such as schizophrenia (SZ) in the later life of offspring. The aim of this study was to evaluate the effects of both FA deficient and FA supplemented diets during gestation and lactation on behavioural parameters, the markers of oxidative stress and neurotrophic factors in adult offspring which had been subjected to an animal model of SZ. Female mother rats (Dam's) were separated into experimental maternal groups, which began receiving a special diet (food) consisting of the AIN-93 diet, a control diet, or an FA deficient diet during the periods of pregnancy and lactation...

we herein report a rare case of methotrexate (MTX)-associated intravascular large B-cell lymphoma (IVLBCL) in a man with rheumatoid arthritis. Two episodes of a fever of unknown origin accompanied by elevated levels of serum lactate dehydrogenase and the soluble interleukin-2 receptor occurred within a year, so the patient was suspected of having an MTX-associated lymphoproliferative disorder. His clinical symptoms resolved after the cessation of MTX. However, after treatment with iguratimod, another disease-modified anti-rheumatic drug, markedly similar symptoms recurred, and random skin biopsies resulted in a diagnosis of IVLBCL...

In the present study, the preventive effects of orally administered disulfiram (DS) against the doxorubicin (DOX)-induced cardiotoxicity were investigated in rats. DS was orally administered for 7 days at doses of 2, 10, and 50 mg/kg/day. DOX (30 mg/kg) was intraperitoneally administered on the 5th day of the initiation of DS treatment. Within 48 h of injection, DOX treatment significantly altered ECG, elevated the ST height, and increased the QT and QRS intervals. It reduced the cardiac levels of injury markers like creatine kinase isoenzyme-MB and lactate dehydrogenase...

Antipsychotic drugs are known to induce neuromuscular effects. In this study, we review 13 years (2002-2014) of antipsychotic intoxications reported by the anti-poisoning center of Algiers (APCA). The most recorded symptoms were neuromuscular/muscular disorders, of which haloperidol was the most inducer among all antipsychotics. A prospective study was conducted between December 2012 and January 2017 to evaluate muscle effects generated after intentional or accidental ingestion of haloperidol. Fifty-one patients admitted in different emergency departments in Algiers were included in this study...

Trazodone (TRZ) is an antidepressant drug commonly used in the treatment of depression, anxiety, and insomnia. Although some studies demonstrated the adverse effects of TRZ related to cardiovascular system, the conflicting results were observed in these studies. Therefore, we aimed to investigate the cardiac adverse effects of TRZ in rats at repeated doses in our study. In accordance with this purpose, TRZ was administered orally to rats at 5, 10, and 20 mg/kg doses for 28 days. Electrocardiogram records, serum aspartate aminotransferase (AST), lactate dehydrogenase, creatine kinase-myoglobin band, cardiac troponin-T (cTn-T) levels, DNA damage in cardiomyocytes, and histologic view of heart tissues were evaluated...

Penehyclidine hydrochloride (PHC), a type of hyoscyamus drug, has both antimuscarinic and antinicotinic activities and retains potent central and peripheral anticholinergic activities. Compared with other hyoscyamine, the notable advantage of PHC is that it has few M2 receptor-associated cardiovascular side effects. Recent studies and clinical trials have suggested that treatment with penehyclidine hydrochloride may also possess good effects in the treatment of lung injury. The mechanism responsible for this effect has yet to be determined; however, one possibility is that they might do so by a direct effect on pulmonary vascular endothelium...

Hexokinase-2 (HK2), the initial as well as the rate-limiting step in glycolysis, is overexpressed in many human cancers, and correlates with poor clinical outcomes. Aerobic glycolysis is a hallmark of cancer, and drugs targeting its enzymes, including HK2, are being developed. However, the mechanisms of HK2 inhibition and the physiological significance of the HK2 inhibitors in cancer cells are rarely reported. Here, we show that microRNA-216a-5p (miR-216a-5p) inhibits HK2 expression by directly targeting its 3'-UTR in uveal melanoma cells...

The molecular mechanisms underlying doxorubicin-induced cardiotoxicity are still being investigated, but are known to involve oxidative stress, mitochondrial dysfunction, and the dysregulation of autophagy. The objective of the current study was to examine the protective role of metformin and its effect on autophagy in doxorubicin-induced cardiotoxicity. Sprague⁻Dawley rats were divided into four groups at random. The doxorubicin-treated group received doxorubicin (3 mg/kg every second day) intraperitoneally...

Metformin drug-drug interaction (DDI) studies are conducted during development of drugs that inhibit organic cation transporters and/or multidrug and toxin extrusion proteins (OCTs/MATEs). Monitoring solely changes in systemic exposure, the typical DDI study endpoint appears inadequate for metformin, which is metabolically stable, has poor passive membrane permeability, and undergoes transporter-mediated tissue distribution and clearance. Evaluation of renal clearance, antihyperglycemic effects, and potentially lactate as an exploratory safety marker, can support rational metformin dose adjustment...

Cancer cells feature a switch in glucose metabolism from oxidative phosphorylation to cytoplasm-based glycolysis. This altered cellular metabolic pathway meets the survival and proliferation needs for tumor progression. Targeting the metabolic remodeling could offer opportunities for developing effective anticancer therapeutics. Human lactate dehydrogenase (hLDH)5 plays a crucial part in the promotion of glycolysis and is overexpressed in various human tumors, and thus could be a potential anticancer drug target...

The majority of renal calculi (kidney stones) are calcium stones. Oxidative damage to renal tubular epithelial cells induced by reactive oxygen species (ROS) is the predominant cause of calcium oxalate stone formation. Hyperoside (Hyp) is a flavonol glycoside extracted from medicinal plants and appears to exhibit potent antioxidant activity in various cells. The aim of the present study was to investigate the protective effect of Hyp on renal cells exposed to oxidative stress simulated by oxalic acid (OA), and to determine whether the underlying mechanism involves the nuclear factor E2‑related factor2 (Nrf2)‑antioxidative response element signaling pathway...

Wnt signaling is important for breast development and remodeling during pregnancy and lactation. Epigenetic modifications change expression levels of components of the Wnt pathway, underlying oncogenic transformation. However, no clear Wnt component increasing expression universally across breast cancer (BC) or its most Wnt-dependent triple-negative BC (TNBC) subgroup has been identified, delaying development of targeted therapies. Here we perform network correlation analysis of expression of >100 Wnt pathway components in hundreds of healthy and cancerous breast tissues...

The role of plasma membrane transporters in the nephrotoxicity of two antiretroviral drugs, cidofovir and tenofovir, was studied in primary cultures of human proximal tubular (hPT) cells. Cells were grown on Transwell filter inserts to maintain epithelial polarity and access to either the apical or basolateral plasma membrane. The function of relevant membrane transporters, organic anion transporter 1 and 3 (OAT1/3), P-glycoprotein (multidrug resistance protein-1; P-gp or MDR1), and organic cation transporter 2 (OCT2), was validated by measurements of apical-to-basolateral and basolateral-to-apical fluxes of furosemide, digoxin, and metformin, respectively...
