Diabetic cardiomyopathy is a cascade of complex events leading to eventual heart failure in diabetes. JQ1, one of Bromodomain and extra-terminal domain (BET) protein inhibitors, has exerted therapeutic effects on cancer proliferation, inflammation and cardiovascular disease. Recently, JQ1 was reported to protect mice from bleomycin-induced lung fib...

Saponins exhibit several biological and pharmacological activities, such as antibacterial, anti-inflammatory and anticancer effects. Many studies attribute their activities to their interactions with cholesterol. In this study, we focus on the steroid saponin ginsenoside Rh2, one of the active principles of Panax ginseng root. Some evidence suggest...

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...

The aim of this study is to characterize the genotoxicity of depleted uranium (DU) in Chinese Hamster Ovary cells (CHO) with mutations in various DNA repair pathways. CHO cells were exposed to 0-300 μM of soluble DU as uranyl acetate (UA) for 0-48 h. Intracellular UA concentrations were measured via inductively coupled mass spectrometry (ICP-MS) an...

While antipsychotic medications provide important relief from debilitating psychotic symptoms, they also have significant adverse side effects, which might have relevant impact on human health. Several research studies, including ours, have shown that commonly used antipsychotics such as haloperidol and aripiprazole affect cholesterol biosynthesis ...

Mammalian cells express unique transcription factors embedded in the endoplasmic reticulum (ER) membrane, such as the sterol regulatory element-binding proteins (SREBPs), that promote de novo lipogenesis. Upon their release from the ER, the SREBPs require proteolytic activation in the Golgi by site-1-protease (S1P). As such, inhibition of S1P, usin...

Nonalcoholic fatty liver disease (NAFLD) is considered to be the most common chronic liver disease. The discovery of natural product-based NAFLD modulators requires a more comprehensive study of their modes of action (MoAs). In this study we analysed available in the literature data for 26 naturally-derived compounds associated with experimental ev...

Liposomalization causes alteration of the pharmacokinetics of encapsulated drugs, and allows delivery to tumor tissues through passive targeting via an enhanced permeation and retention (EPR) effect. PEGylated liposomal doxorubicin (Doxil®, Lipo-DXR), a representative liposomal drug, is well-known to reduce cardiotoxicity and increase the anti-tumo...

This article reports novel results about nanotoxicological and teratogenic effects of the PAMAM dendrimers DG4 and DG4.5 in zebrafish (Danio rerio). Zebrafish embryos and larvae were used as a rapid, high-throughput, cost-effective whole-animal model. The objective was to provide a more comprehensive and predictive developmental toxicity screening ...

Protein phosphatase 2A (PP2A) is a serine-threonine phosphatase that regulates cell signaling pathways. Its inactivation is correlated with tumor malignancy, possibly due to the effects on cell differentiation and malignant cell transformation. Therefore, it has been noted that PP2A could be a promising target for cancer therapy. In our previous st...
