Abstract
BACKGROUND The efficacy of chemotherapy continues to be limited due to associated toxicity and chemoresistance. Thus, synthesizing and investigating novel agents for cancer treatment that could potentially eliminate such limitations is imperative. OBJECTIVE The current study aims to explore the anticancer potency of cryptolepine (CPE) analog on Ehrlich ascites carcinoma cells (EACs) in mice. METHODS The effect of a CPE analog on EAC cell viability and ascites volume, as well as malonaldehyde, total antioxidant capacity, and catalase, were estimated. The concentration of caspase-8 and mTOR in EACs was also measured, and the expression levels of PTEN and Akt were determined. RESULTS Results revealed that CPE analog exerts a cytotoxic effect on EAC cell viability and reduces the ascites volume. Moreover, this analog induces oxidative stress in EACs by increasing the level of malonaldehyde and decreasing the level of total antioxidant capacity and catalase activity. It also induces apoptosis by elevating the concentration of caspase-8 in EACs. Furthermore, it decreases the concentration of mTOR in EACs. Moreover, it upregulates the expression of PTEN and downregulates the expression of Akt in EACs. CONCLUSION Our findings showed the anticancer activity of CPE analog against EACs in mice mediated by regulation of the PTEN/Akt/mTOR signaling pathway.

Abstract
Clinically, the use of doxorubicin (DOX) is limited due to DOX-induced cardiotoxicity (DIC). The current study aimed to evaluate the cardioprotective effect of trehalose (TRE) against DIC in a female Swiss albino mouse model. Mice were divided into five experimental groups: Gp. I: saline control group (200 μl/mouse saline three times per week for 3 weeks day after day), Gp. II: DOX-treated group (2 mg/kg body weight three times per week for 3 weeks day after day), Gp. III: TRE group (200 μg/mouse three times per week for 3 weeks day after day), Gp. IV: DOX + TRE cotreatment group (animals were coadministered with DOX and TRE as in Gp. II and III, respectively), and Gp. V: DOX + TRE posttreatment group (animals were treated with DOX as in Gp. II followed by treatment with TRE as in Gp. III). DOX-treated mice showed significant elevation in cardiac injury biomarkers (lactate dehydrogenase, creatine kinase isoenzyme-MB, and cardiac troponin I), cardiac oxidative stress (OS) markers (malondialdehyde and myeloperoxidase), and cardiac levels of autophagy-related protein 5. Moreover, DOX significantly reduced the levels of total antioxidant capacity and activities of catalase and glutathione S-transferase. In contrast, TRE treatment of DOX-administered mice significantly improved almost all of the above-mentioned assessed parameters. Furthermore, histopathological changes of cardiac tissues observed in mice treated with TRE in combination with DOX were significantly improved as compared to DOX-treated animals. Taken together, the present study provides evidence that TRE has cardioprotective effects against DIC, which is likely mediated via suppression of OS and autophagy.

Abstract
The anticancer effect of sulforaphane (SFN) is mediated by several signalling pathways. However, little is known regarding the underlying mechanism in Ehrlich solid tumours (ESTs) in mice. This study was conducted to determine molecular changes associated with the anticancer effect of SFN and to compare its preventive (cotreatment) and therapeutic (posttreatment) effects. Ehrlich (murine mammary adenocarcinoma) solid tumour was selected and changes in the gene expression were determined in tumour tissues by the real-time polymerase chain reaction. The results showed that SFN increased the expression of the oxidative stress gene NrF2 and its downstream targets (HO1 and CAT). Conversely, SFN administration decreased the expression of the epigenesis-related genes (HDAC1 and DNMT1) and inflammation-related genes (TNFa, NFkB and Cox2). Overall, SFN cotreatment presented notable molecular changes than the posttreatment strategy. These data suggest that molecular changes associated with the anticancer effects of SFN against EST involved induction of oxidative stress, inhibition of inflammation and epigenetic modifications.

Abstract
The current study aims to evaluate the modulatory effect of zinc oxide nanoparticles (ZnO NPs) on the bioenergetic signature biomarkers in the Ehrlich ascitic carcinoma (EAC) model. To achieve this goal, 90 female albino mice were included in this study and were divided into six equal groups (n =15 per group): saline-treated group, ZnO NP-treated, EACs-bearing mice, and three groups of EACs-bearing mice treated with ZnO NPs at a dose of 20 mg/kg every other day, 10 mg/kg every other day, 10 mg/kg every day, respectively, for 14 days. The tissues from treated groups and control groups were homogenized and used for the assay of glyceraldehyde 3-phosphate dehydrogenase (GAPDH) and F1 beta subunit of adenosine triphosphate (ATP) synthase levels, as well as the determination of lactate level. The survival time of mice was improved in all ZnO NP-treated groups, especially in EACs-bearing mice treated with ZnO NPs at a dose of 10 mg/kg every other day. This improvement was associated with an increased F1 beta subunit of ATP synthase level and a decreased GAPDH level. Also, the lactate level was significantly decreased in all treated groups when compared with the untreated group. The overall effect was the increased bioenergetic signature as compared with EC.These results implied that ZnO NPs have a significant efficacy against cancer cells and they significantly increased the bioenergetic signature.

Abstract
Neurodegenerative diseases are a common cause of morbidity and mortality worldwide, with oxidative stress, inflammation, and protein aggregation representing the main underlying mechanisms that ultimately lead to cell death. Ethanol has shown strong neurodegenerative consequences in experimental animal brains. Statins are a class of lipid-lowering drugs with many pleotropic effects. Therefore, the aim of the present study was to explore the modulatory effect of simvastatin (10 mg·kg-1·day-1) before and after the development of neurodegeneration (for 55 and 25 days, respectively) on redox state, caspase-3 expression, p-protein kinase B (p-Akt), and brain-derived neurotrophic factor (BDNF) in ethanol-induced (15% ethanol solution for 55 days) neurodegeneration. Seventy female Albino Swiss mice were included and randomly divided into five groups: C, control group; E, ethanol group; ES, group treated with simvastatin from the first day of ethanol intake; E + S, group treated with simvastatin after neurodegeneration development; and S, simvastatin group. Administration of simvastatin from the first day improved the biochemical changes, suppressed apoptosis, and induced autophagy and neurogenesis; however, its administration after the development of neurodegeneration resulted in partial improvement. The histopathological findings confirmed the biochemical changes. In conclusion, simvastatin has a neuroprotective effect against the development of ethanol-induced neurodegeneration and its progression.

Abstract
Cancer cells have extra biosynthetic demands to sustain cell growth and redox homeostasis. Glycolysis and autophagy are crucial to fuel and recycle these biosynthetic demands. This plasticity of cancer cell metabolism participates in therapy resistances. The current study was designed to assess the therapeutic efficacy of dual targeting of glycolysis and autophagy in cancer. Using 3-bromopyruvate (3-BP; antiglycolytic inhibitor) and hydroxychloroquine (HCQ; autophagy inhibitor), we demonstrate their antitumor activity in Ehrlich ascites carcinoma (EAC)-bearing mice. A combination of 3-BP and HCQ significantly decreases tumor ascitic volume and cell count as compared with the EAC group and individual treatment groups. The enhanced antitumor activity is accompanied by hexokinase inactivation, inhibition of cellular protective autophagy, elevated antioxidant activity, and reduced oxidative stress levels. Together, these results suggest targeting both pathways in cancer as an effective therapeutic strategy. Further studies are required to validate this strategy in different cancer models and preclinical trials.

Abstract
The mean strength that has traditionally been taken as a measurement of the strength of a material does not reflect the true strength, and therefore it cannot be used as a design parameter. This explains why many brittle materials fail at unpredictable stress, either below or above the mean strength. By using Weibull statistics, the prediction and assessment of strength can be made more sensibly. The performance of a material can be predicted by considering a stress at a lower level of failure probability.
