Abstract
Improving radiation effect on tumor cells using radiosensitizers is gaining traction for improving chemoradiotherapy. This study aimed to evaluate copper nanoparticles (CuNPs) synthesized using chrysin as radiosensitizer with γ-radiation on biochemical and histopathological approaches in mice bearing Ehrlich solid tumor. CuNPs were characterized with irregular round sharp shape with size range of 21.19-70.79 nm and plasmon absorption at 273 nm. In vitro study on MCF-7 cells detected cytotoxic effect of CuNPs with IC50 of 57.2 ± 3.1 μg. In vivo study was performed on mice transplanted with Ehrlich solid tumor (EC). Mice were injected with CuNPs (0.67 mg/kg body weight) and/or exposed to low dose of gamma radiation (0.5 Gy). EC mice exposed to combined treatment of CuNPs and radiation showed a marked reduction in tumor volume, ALT and CAT, creatinine, calcium, and GSH, along with elevation in MDA, caspase-3 in parallel with inhibition of NF-κB, p38 MAPK, and cyclin D1 gene expression. Comparing histopathological findings of treatment groups ends that combined treatment was of higher efficacy, showing tumor tissue regression and increase in apoptotic cells. In conclusion, CuNPs with a low dose of gamma radiation showed more powerful ability for tumor suppression via promoting oxidative state, stimulating apoptosis, and inhibiting proliferation pathway through p38MAPK/NF-κB and cyclinD1.

Abstract
In this study, we present a multifunctional hybrid hydrogel (MFHH) for the prevention of postoperative tumor recurrence. MFHH consists of two components; component A - containing a gelatin-based cisplatin, which destroys the residual cancer after surgery, and component B - containing macroporous gelatin microcarriers (CultiSpher) loaded with freeze-dried bone marrow stem cells (BMSCs), which activates the wound healing process. We also evaluated the effects of MFHH in a subcutaneous Ehrlich tumor mouse model. MFHH acted as a local delivery system by directly supplying cisplatin to the tumor environment, resulting in excellent anti-cancer effects and minimal side effects. MFHH released cisplatin gradually to destroy the residual tumors, thereby preventing loco-regional recurrence. We have also demonstrated that BMSCs are able to inhibit residual tumor growth. Moreover, CultiSpher loaded with BMSCs acted as an injection 3D scaffold and easily filled the wound defect formed by tumor removal, and the paracrine factors of the freeze-dried BMSCs accelerated the wound healing process. The components of the MFHH can be used both separately and together. However, for the successful application of MFHH in clinical practice, it is necessary to study in more detail the role of paracrine factors of freeze-dried BMSCs in the inhibition or proliferation of residual cancer. These questions will be the focus of our future research.

Abstract
OBJECTIVE Our objective was to explore the effect of different fractionation schedule on ferroptosis and pyroptosis biomarkers as new cell death mechanisms induced by IR. MATERIALS AND METHODS This study included 40 tumor bearing mice divided into: Group I: Includes 8 untreated tumor-bearing mice. Group II: Includes 8 tumor bearing mice exposed to single dose 6 Gy of IR. Group III: Includes 8 tumor bearing mice exposed to 12 Gy in 2 fractions (2 × 6 Gy) of IR. Group IV: Includes 8 tumor bearing mice exposed to 12 Gy in 3 fractions (3 × 4 Gy) of IR. Group V: Includes 8 tumor bearing mice exposed to 8 Gy in 4 fractions (4 × 2 Gy) of IR. IL-1β, IL-18, and GSDMD-CT levels were assessed by ELISA. PTGS2 and ACSL4 expression were assessed by RT-PCR. RESULTS (2 × 6 Gy) group showed the highest ACSL4 expression followed by (3 × 4 Gy), then (4 × 2 Gy) and finally 6 Gy. (2 × 6 Gy) group resulted in the highest PTGS2 expression followed by (3 × 4 Gy), then 6 Gy, and finally (4 × 2 Gy). MDA significantly increased at (2 × 6 Gy), (3 × 4 Gy), and 6 Gy groups and insignificantly increased at (4 × 2 Gy) group. Iron significantly increased at (2 × 6 Gy), (3 × 4 Gy), and (4 × 2 Gy) groups and insignificantly at 6 Gy. Glutathione was significantly decreased at (2 × 6 Gy), (3 × 4 Gy), and (4 × 2 Gy) groups and insignificantly at 6 Gy. GSDMD-CT, IL-1β, and IL-18 levels significantly reduced in tumor tissues after exposure to IR at all doses. CONCLUSION High dose per fraction regimens induce the expression of ferroptosis markers more than low dose per fraction regimen and single dose of IR. IR at all doses induces pyroptotic cell death.

Abstract
OBJECTIVE The chemo-preventative and therapeutic properties of selenium nanoparticles (SeNPs) have been documented over recent decades and suggest the potential uses of SeNPs in medicine. Biogenic SeNPs have higher biocompatibility and stability than chemically synthesized nanoparticles, which enhances their medical applications, especially in the field of cancer therapy. This study evaluated the potential of green-synthetized SeNPs by using berberine (Ber) as an antitumor agent and elucidated the mechanism by which these molecules combat Ehrlich solid tumors (ESTs). METHODS SeNPs containing Ber (SeNPs-Ber) were synthesized using Ber and Na2SeO3 and characterized with Fourier transform infrared spectroscopy. Sixty male Swiss albino mice were then acclimatized for one week, injected with Ehrlich ascites tumor cells, and divided into four groups: EST, EST + cisplatin (5 mg/kg), EST + Ber (20 mg/kg), and EST + SeNPs-Ber (0.5 mg/kg). At the end of a 16-day observation period, 12 mice from each group were euthanized to analyze differences in the body weight, tumor size, gene expression, and oxidative stress markers in the four groups. Three mice from each group were kept alive to compare the survival rates. RESULTS Treatment with SeNPs-Ber significantly improved the survival rate and decreased the body weight and tumor size, compared to the EST group. SeNPs-Ber reduced oxidative stress in tumor tissue, as indicated by a decrease in the lipid peroxidation and nitric oxide levels and an increase in the glutathione levels. Moreover, SeNPs-Ber activated an apoptotic cascade in the tumor cells by downregulating the B-cell lymphoma 2 (Bcl-2) expression rate and upregulating the Bcl-2-associated X protein and caspase-3 expression rates. SeNPs-Ber also considerably improved the histopathological alterations in the developed tumor tissue, compared to the EST group. CONCLUSION Our study provides a new insight into the potential role of green-synthesized SeNPs by using Ber as a promising anticancer agent, these molecules could be used alone or as supplementary medication during chemotherapy.

Abstract
Despite considerable advances in cancer treatment, chemotherapy remains a cornerstone in breast cancer therapy. Therefore, reducing chemoresistance and adverse effects of chemotherapy is a priority. In this regard, Baicalin (BA) is the dominant natural flavonoid extracted from the roots of Scutellaria baicalensis showed fascinating antitumor activity in many types of cancers, including breast cancer. The present study aimed to explore the chemopreventive and antitumor action of baicalin alone and in combination with 5-FU in addition to its ability to enhance the antitumor effect of 5-FU on breast cancer using the Ehrlich solid tumor-mice model. MATERIALS AND METHODS A total of 70 female mice were divided into seven groups (1st group, saline group; 2nd group, DMSO group; 3rd group, BA+EST group; 4th group, EST group; 5th group, EST+5-FU; 6th group, EST+BA group; 7th group, EST+5-FU+BA).tumors were assessed by weight and histopathological examination. Inflammation, angiogenesis, and apoptosis were examined by ELISA, qRT-PCR, and immunohistochemical examinations. RESULTS showed that pre-treatment with baicalin and treatment with baicalin and/or 5-FU significantly reduced inflammation and angiogenesis indicated by suppression of NF-kB/ IL-1β and VEGF amplification loop with marked elevation in apoptosis indicated by up-regulation of apoptotic caspase-3, pro-apoptotic p53, Bax and downregulation of anti-apoptotic Bcl-2. CONCLUSION BA is a promising preventive or adjuvant therapy in breast cancer treatment with 5-FU mainly via cooperative inhibition of inflammation, angiogenesis, and triggering apoptotic cell death.

Abstract
This study evaluated the ameliorative potential of grape seed extract (GSE) against Ehrlich solid tumor (EST)-induced hepatic tissue alterations in mice. The control group was infused with physiological saline. The second group received GSE (50 mg/kg day by day orally) for 2 weeks. The third group was subcutaneously injected with 2.5 million of EST cells. The fourth group was injected with EST cells and treated with GSE extract simultaneously. The fifth group was injected with EST cells and kept for 2 weeks until the appearance of a solid tumor, then treated with GSE for 2 weeks. The phytochemical analysis of GSE revealed the presence of total phenols (17.442 mg GAE/g) and total flavonoid (6.687 mg CE/g) with antioxidant activity of 81.506 mg TE/g DPPH. The Ehrlich solid tumor significantly raised the activities of ALT, AST, and ALP; the level of alpha fetoprotein (AFP) in serum; and the protein expressions of hepatic proliferating cell nuclear antigen (PCNA) and tumor suppressor protein (P53), as well as induced DNA damage and pathological alterations in liver tissue. However, it significantly reduced serum albumin and total protein levels. In contrast, the co- or post-treatment of EST-bearing mice with GSE reduced the activities of ALT, AST, and ALP; the level AFP in serum; and hepatic P53 and PCNA protein expressions. In addition, it reduced EST-induced hepatic DNA damage and pathological alterations, while it increased serum albumin and total protein levels. This study suggested that GSE is a potent hepatoprotective agent and both co- and post-treatment of EST-bearing mice with GSE almost had the same effects.

Abstract
Background The anti-cancer effect of the halophyte Arthrocnemum indicum, a member of Arthrocnemum family of salt-tolerant plants, was evaluated against colorectal cancer cell, CaCo2. However, the anti-cancer effect of another halophyte Arthrocnemum machrostachyum was not investigated yet. Herein, the anticancer effect of A. machrostachyum methanolic extract (AME) was evaluated against Ehrlich solid tumor (EST) in mice and the potential mechanism of action was also studied. Methods Male Swiss albino mice (n = 28) were randomly divided into 4 groups (n = 7/group). Group 1 (negative control group); group 2 (EST) injected intramuscularly by 0.2 mL Ehrlich ascitic carcinoma (2 × 106 cells); and groups 3 and 4 injected intratumorally with AME (180 and 360 mg/kg body weight, respectively) at D12 trice weekly for 2 weeks. Gene expression, protein expression, DNA damage, and TNFa level in tumors were determined by real-time PCR, western blot, comet assay, and Elisa, respectively. Results Treatment with AME induced anti-tumor effects against EST as indicated by 1) notable reduction in tumor size; 2) elevation in tissue necrosis and apoptosis, as confirmed histologically; 3) increased DNA fragmentation; 4) decreased expression of the apoptotic genes (p53, Bax and caspase 3), and increased expression of the anti-apoptotic marker Bcl2; 5) significantly upregulated cell cycle regulatory genes Cdc2 and connexin26, and; 6) decreased TNFa levels in tumor tissues. Interestingly, a high dose of AME exhibited a more potent anti-tumor effect against EST. Conclusion These findings indicate that AME has a potent antitumor effect against EST and could be used as an adjuvant to anticancer drugs to combat tumor, but after application of further confirmatory clinical trials.

Abstract
AIM Cornus mas L is commonly used due to its anti-inflammatory, anti-carcinogenic and anti-oxidant properties. In the study, the effects of C. mas L extract on a solid tumor were examined in the Ehrlich solid tumor model developed in Balb/C type mice. METHODS Ehrlich acid tumor (EAT) cells (1x106 EAT cell) from the stock animal were injected subcutaneously (s.c.) through the nape of the mice. Treatment groups of solid tumor-induced animals received 100 mg/kg and 200 mg/kg of C. mas L extract intraperitoneally (i.p.) for 14 days. RESULTS Tumor volumes and animal weights were found to be statistically significant compared to the control group (p < 0.05). AgNOR staining was performed in tumor tissues. Statistically significant differences were observed between the groups in terms of TAA/NA ratio (p < 0.05). Immunohistochemical and biochemical parameters were also evaluated. An estimation of tumor proliferation of the lung, liver, brain, kidney, testis and tumor antioxidant parameters viz. lipid peroxidation, reduced glutathione (GSH), glutathione S-transferase (GST), superoxide dismutase (SOD) and catalase (CAT) was made. CONCLUSIONS Our study showed that the anti-tumor effect of C. mas L in assisted tumor development with EAT cells, was mediated by the enhancement of oxidative stress with multiple mechanisms (Tab. 6, Fig. 12, Ref. 38).

Abstract
The current study was carried out to evaluate the protective effect of grape seed proanthocyanidins extract (GSPE) against Ehrlich solid tumor (EST) induced renal injury, with the respect to DNA fragmentation and P53 and PCNA proteins expression in renal tissue. A total of 50 female mice were randomly assigned into five groups. Control mice were injected with physiological saline solution. Mice of the 2nd group were administered with GSPE (50 mg/kg bw/every 2day/per OS) for 2 weeks and injected with physiological saline solution. Mice of the 3rd group were injected subcutaneously with 2.5 million cells of EAC/mouse. Mice of the 4th group were injected with EAC as the 3rd group and administered with GSPE as the 2nd group simultaneously for 2 weeks. Mice of the 5th group were injected with EAC as the 3rd group and left for 2 weeks (till development of solid tumor), then treated with GSPE for another 2 weeks. EST significantly increased serum levels of urea, creatinine, potassium and chloride. In addition, it induced renal tissue and DNA injuries and increased P53, PCNA and ki67 proteins expression in renal tissues. On the other hand, it decreased serum levels of sodium and calcium ions. However, treatment of EST bearing mice with GSPE normalized serum levels of the above-mentioned parameters and improved renal tissue structure and reduced renal tissue DNA damage and P53, PCNA and ki67 proteins expression. These results indicated that GSPE is a promising nephron protective agent against EST induced renal injury.

Abstract
The present study investigated the antineoplastic effects of pectic polysaccharides that were extracted from green sweet pepper (Capsicum annuum [CAP]) in the Ehrlich carcinoma in mice and in human mammary tumor lineages. After the subcutaneous inoculation of 2 × 106 Ehrlich tumor cells, Female Swiss mice received 50, 100, or 150 mg/kg CAP or vehicle orally once daily or methotrexate (2.5 mg/kg, i.p., every 5 days) for 21 days. CAP dose-dependently reduced Ehrlich tumor growth. It also reduced the viability of MCF-7, MDA-MB-231, and MDA-MB-436 human mammary cell lineages. Treatment with CAP reduced the gene expression of vascular endothelial growth factor in vivo and in vitro, reduced vessel areas of the tumors, and induced necrosis in Ehrlich solid tumors. CAP treatment significantly increased Interleukin-6 in tumors. The antineoplastic effect of CAP appears to depend on the regulation of inflammation and angiogenesis. Further studies are encouraged to better understand the CAP potential for the treatment of breast tumors.

Abstract
Guided treatments with nanoparticles and radiotherapy are a new approach in cancer therapy. This study evaluated the beneficial antitumor effects of γ-radiation together with gallium nanoparticles against solid Ehrlich carcinoma in female mice. Gallium nanoparticles were biologically synthesized using Lactobacillus helveticus cells. Transmission electron microscopy showed gallium nanoparticles with size range of 8-20 nm. In vitro study of gallium nanoparticles on MCF-7 revealed IC50 of 8.0 μg. Gallium nanoparticles (0.1 mg/kg body weight) were injected intraperitoneally daily on the seventh day of Ehrlich carcinoma cells inoculation. Whole-body γ-radiation was carried out at a single dose of 0.25 Gy on eighth day after tumor inoculation. Biochemical analysis showed that solid Ehrlich carcinoma induced a significant increase in alanine aminotransferase activity and creatinine level in serum, calcium, and iron concentrations in liver tissue compared to normal control. Treatment of Ehrlich carcinoma-bearing mice with gallium nanoparticles and/or low dose of γ-radiation exposure significantly reduced tumor volume, decreased alanine aminotransferase and creatinine levels in serum, increased lipid peroxidation, and decreased glutathione content as well as calcium and iron concentrations in liver and tumor tissues with intense DNA fragmentation accompanied compared to untreated tumor cells. Moreover, mitochondria in the treated groups displayed a significant increase in Na+/K+-ATPase, complexes II and III with significant reduction in CYP450 gene expression, which may indicate a synergistic effect of gallium nanoparticles and/or low dose of γ-radiation combination against Ehrlich carcinoma injury, and this results were well appreciated with the histopathological findings in the tumor tissue. We conclude that combined treatment of gallium nanoparticles and low dose of gamma-radiation resulted in suppressive induction of cytotoxic effects on cancer cells.

Abstract
Combining chemotherapy with radiotherapy represents a key oncology strategy for a more comprehensive attack toward cancers and improves treatment outcome for various solid tumor malignancies. The present study aims to evaluate the synergistic antitumor effect of γ-radiation together with gallium trichloride (GaCl3) and/or doxorubicin (DOX) against solid Ehrlich carcinoma (EC) in female mice. GaCl3 (300 mg/kg body weight (b.w.)) was administered by gavages daily on the seventh day after tumor inoculation, while the cytotoxic drug DOX (4 mg/kg b.w.) was administered intraperitoneally once a week. Whole-body γ-radiation was carried out at a dose 2 Gy once a week. Biochemical analysis showed that solid EC induced a significant increase in malondialdehyde (MDA) content with a significant decrease in the antioxidant state (glutathione peroxidase (GPx) and catalase (CAT) activities) and depleted serum iron concentration compared to normal control. Moreover, a significant increase was observed in calcium level and caspase-3 concentrations in both serum and tumor homogenate respectively associated with a significant alteration in heart, liver, and kidney functions, as compared to control. Treatment of EC-bearing mice with GaCl3and/or DOX combined with γ-radiation exposure significantly reduced tumor volume and displayed a significant improvement in most studied markers which may indicate a synergistic effect of this combination against organ dysfunction and cellular injury. The histopathologically investigation showed that treatment of animals bearing EC with GaCl3and/or DOX with γ-radiation exposure showed shrinkage in tumor lesions and wide zones of apoptotic cells with signs of regenerations. It was concluded that the combination of GaCl3and/or DOX with γ-radiation exposure resulted in super-additive cytotoxic effects on treatment of cancer cells.

Abstract
The genus Calea is reported for many biological activities such as antiinflammatory, antiplasmodial, antifungal, antimicrobial, and cytotoxic activities. Most of the pharmacological activities are credited to germacranolides, a sesquiterpene lactone common to this genus. Dried aerial parts of Calea pinnatifida Banks were extracted with dichloromethane, which generated the dichloromethane crude extract (DCE). The main purpose of this study was to evaluate the anticancer activity of DCE performed in sulforhodamine B cytotoxicity in vitro assay against human cancer cell lines and in vivo Ehrlich models. The DCE showed a high potency and selectivity for the melanoma and kidney cell line. Two in vivo assays were also conducted in the Ehrlich ascites tumor and Ehrlich solid tumor. In the Ehrlich ascites tumor assay, the treatment with DCE increased survival rates at the highest dose (200 mg/kg). Interestingly, in the Ehrlich solid tumor, by increasing the number of treatments from one to three times a week, the tumor growth was inhibited by a lower dose (100 mg/kg). These results encouraged follow-up studies with C. pinnatifida in order to identify the active principles and to determine the anticancer mechanism of action.
