Abstract
Chemotherapy agents in breast cancer are associated with chemotherapy-related cognitive impairments (CRCI). Mechanisms are not fully clear, but alterations of glucose and lipid metabolism, neuroinflammation and neurodegeneration may contribute to CRCI. The aim of this study was to investigate the combined effects of a high fat (HF) diet combined with doxorubicin-based chemotherapy on glucose and lipid metabolism, neuroinflammation, and neurodegeneration in mice. Additionally, we examined the therapeutic potential of dietary eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) to attenuate these effects. Female C57Bl/6 mice (n = 42) were fed HF, HFn-3 (2 % kcals as EPA + DHA) or Low Fat (LF) diets for seven weeks, with and without chemotherapy. In this study, two chemotherapy injections led to weight and body fat loss associated with a decrease in insulin resistance measured by HOMA-IR. HOMA-IR was significantly greater in HF versus LF groups; but HOMA-IR in HFn-3 group did not significantly differ from either HF or LF groups. Chemotherapy resulted in higher brain concentrations of the inflammatory chemokine KC/GRO. Compared to LF diet plus chemotherapy, HF diet plus chemotherapy upregulated multiple genes involved in neuroinflammation and neurodegeneration pathways. HFn-3 diet plus chemotherapy attenuated gene expression by downregulating multiple genes involved in neuroinflammation and blood brain barrier regulation, including Mapkapk2, Aqp4, and s100b, and upregulating Kcnb1 and Atxn3, genes involved in reduction of oxidative stress and anxiety, respectively. Overall, a HF diet combined with chemotherapy is associated with neuroinflammatory and neurodegenerative gene expression changes in this mouse model; dietary enrichment of EPA and DHA attenuated these effects. Further studies are needed to understand how diet impacts behavioral outcomes of CRCI.

Abstract
Since several decades, the prodrug concept has raised considerable interest in cancer research due to its potential to overcome common problems associated with chemotherapy. However, for small‐molecule tyrosine kinase inhibitors, which also cause severe side effects, hardly any strategies to generate prodrugs for therapeutic improvement have been reported so far. Here, we present the synthesis and biological investigation of a cathepsin B‐cleavable prodrug of the VEGFR inhibitor sunitinib. Cell viability assays and Western blot analyses revealed, that, in contrast to the non‐cathepsin B‐cleavable reference compound, the prodrug shows activity comparable to the original drug sunitinib in the highly cathepsin B‐expressing cell lines Caki‐1 and RU‐MH. Moreover, a cathepsin B cleavage assay confirmed the desired enzymatic activation of the prodrug. Together, the obtained data show that the concept of cathepsin B‐cleavable prodrugs can be transferred to the class of targeted therapeutics, allowing the development of optimized tyrosine kinase inhibitors for the treatment of cancer.

Abstract
BACKGROUND To compare the efficacy and toxicity of peptide-doxorubicin (PDOX) and doxorubicin (DOX) on nude mice models of human gastric cancer. RESULTS Both PDOX and DOX could significantly inhibit tumor growth compared with Control (P < 0.05) in both subcutaneous and orthotopic models. Animal survival was much better in PDOX group than DOX group. In peripheral blood test, PDOX group had significantly higher levels of platelets than the Control (P < 0.05), and lymphocyte lower than Control (P < 0.05). There were no significant differences on liver, kidney and cardiac function parameters among three groups (P > 0.05). Immunohistochemistry showed that treatment groups had much higher Tunel than Control (P < 0.05), and PDOX had significantly lower Ki-67 than doxorubicin and Control group (P < 0.01). Western blotting showed that PDOX caused much higher expressions of P53, P21, Aparf-1, pro- and cleaved-caspase 3, compared with DOX. CONCLUSION Compared with DOX, PDOX has increased effects but much decreased toxicity in treating animal model of gastric cancer. MATERIALS AND METHODS Animals in subcutaneous model were randomized into Control, doxorubicin, PDOX-L, PDOX-M, and PDOX-H groups. Animals in surgical orthotopic implantation model were randomized into Control, doxorubicin and, peptide-doxorubicin groups. The animals were treated, monitored and examined following a set protocol.

Comparison of anticancer effect of Pleurotus ostreatus extract with doxorubicin hydrochloride alone and plus thermotherapy on erythroleukemia cell line. JOURNAL OF COMPLEMENTARY & INTEGRATIVE MEDICINE 2017; 15:/j/jcim.ahead-of-print/jcim-2016-0136/jcim-2016-0136.xml. [PMID: 29257758 DOI: 10.1515/jcim-2016-0136] [Citation(s) in RCA: 4] [Impact Index Per Article: 0.6] [Reference Citation Analysis] [Abstract] [Key Words] [Track Full Text] [Subscribe] [Scholar Register] [Received: 02/28/2017] [Accepted: 10/16/2017] [Indexed: 11/15/2022]
Abstract
Background Recent studies have introduced Pleurotus ostreatus (Pleurotaceae) as a herbal medicine for treating different types of cancer. This survey utilizes P. ostreatus and doxorubicin hydrochloride (DOX) alone and then with hyperthermia to investigate the erythroleukemia cell line. This study evaluates and compares the apoptotic and necrotic effects of various treatments on the KG-1 cell line. Methods The proliferation of KG-1 cells was measured by using a tetrazolium salt (MTT)-based colorimetric assay during 96 h after treatment by gradient dilutions of 100 ng/mL to 100 mg/mL of P. ostreatus methanol extract and then the minimum inhibitory concentration (MIC) was determined and was applied in additional experiments. Afterward, the cells were treated using P. ostreatus extract, DOX (6.95 mg/L), and hyperthermia (42 and 44 °C), separately and then applying hyperthermia. Finally, the ratios of apoptosis and necrosis after 24 h incubation were evaluated by using flow cytometry. Results The MIC of the extract was determined (1 mg/mL), which significantly increased the ratio of apoptosis rather than necrosis, whereas the DOX treatment primarily induced necrosis on the KG-1 cells. The anticancer effects of the mushroom extract were significantly increased when it was combined with thermotherapy, which exhibited apoptotic effects at 42 °C but induced necrosis at 44 °C. Conclusions The results suggest that P. ostreatus extract induces apoptosis on KG-1 cells and its anticancer effects are significantly increased in combination with thermotherapy. Therefore, P. ostreatus could be considered as an alternative with anticancer effect for further studies in erythroleukemia patients.
