Material & Methods: Twenty-four female rats were used in this study. Six rats were preserved without treatment and the other eighteen female rats were induced by a single dose of MNU (50 mg /kg B wt). After confirmation of the positive tumor marker test, female rats were placed with the males for mating. The pregnant rats were divided into four groups (n=6). Group1: control rats, group2: Quercetin supplemented rats (20 mg/kg B.Wt, group3: MNU-induced rats, and group4: MNUtreated rats followed by supplementation with quercetin. At the end of the weaning period, the mothers and their offspring (at 21 days old postnatal) of all groups were sacrificed, the liver was removed immediately for histological and immunohistochemical investigations. Also, blood samples were collected, centrifuged, and processed for the estimation of antioxidants. Results: In the control and quercetin groups, the histological investigation of the liver of mother rats and their offspring appeared with normal architecture. In Group3 (MNU-induced group) the liver sections of mother's rats revealed degenerated hepatic lobules with pronounced cellular hyperplasia (HCC) especially around the central vein and portal area as well as numerous Kupffer cells and fat droplets. However, the liver sections of offspring displayed little cellular hyperplasia but the central and portal veins appeared damaged and congested with blood. Immunohistochemically, the liver sections of MNU-induced mother's rats and their offspring appeared strongly stained with α-FP antibody and negatively stained with caspase-3 antibody. Furthermore, the levels of serum antioxidants; SOD, CAT&GSH were significantly decreased however the levels of MDA and NO were significantly increased in MNU-induced mother rats and their offspring if compared with control. In group 4, quercetin was able to restore the histological and immunohistochemical changes in the liver induced by MNU. Also, the levels of antioxidants, as well as MDA and NO, were markedly restored near to the normal level as in control. Conclusion: Quercetin has a powerful therapeutic role against MNU-induced HCC in pregnant rats and their offspring.","PeriodicalId":15163,"journal":{"name":"Journal of Bioscience and Applied Research","volume":"80 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-12","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"74855806","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

MDA-MB231 cells showed more sensitivity to imatinib mesylate than to dipyridamole, with an IC50 value of 348 g/mL versus 494 g/mL for imatinib mesylate and dipyridamole, respectively (P-value < 0.05). The up/downregulation of Bax and Bcl2 and metastasis contributing gene (MMP-1) assured the anticancer activity. Also, the apoptotic potential of dipyridamole and imatinib mesylate was verified by arresting cells in the G2/M phase and increasing the percentage of the apoptotic cells in the pre-G1 phase. The antioxidant levels were drug dependent, as they were significantly higher(P<0.05) in cells treated with imatinib than in cells treated with Dipyridamole. Conclusion: Imatinib mesylate growth-inhibitory impact on breast cell lines, either alone or in combination with dipyridamole, may be mediated through up/downregulation of the Bax, Bcl-2, and MMP-1 genes. Imatinib is a promising treatment for breast cancer patients who require targeted therapy.","PeriodicalId":15163,"journal":{"name":"Journal of Bioscience and Applied Research","volume":"541 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-12-01","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"88120864","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

Therefore, further investigation is required to determine the potential prenatal hazard of this compound and to introduce possible treatment for these hazards. This study aimed to assess the biochemical, histopathological, and ultrastructural changes induced by diphenylamine in the developing liver and kidney of rat fetuses and the role of vitamin E in alleviating these changes. Fifty pregnant rats were divided equally into five groups, the group I was administrated distilled water, group II was administrated corn oil, group III was administrated 100 mg/kg/b.wt. vitamin E, group IV was administrated approximately 400 mg/kg/b.wt diphenylamine and group V was administrated diphenylamine + vitamin E at the above-mentioned doses from the 6 to 15 day of pregnancy. Diphenylamine induced undesirable histopathological and ultrastructural changes in the fetal liver and kidney. These changes were in the form of vacuolation, congestions of central veins, hemorrhage, leucocytic infiltration, degenerated cytoplasm, pyknotic nuclei, and swollen mitochondria and rER of hepatocytes. While the degenerative changes in the kidney were represented by degenerated brush border, lumen dilation, tubular hyalinization, vacuolation, degenerated nuclei, and mitochondria. Also, there was a significant decrease in the antioxidant enzymes i.e., superoxide dismutase and catalase, and a significant increase in reactive oxygen radicals and malondialdehyde. Treatment with vitamins E after diphenylamine restored all biochemical, histopathological, and ultrastructural damage cited above. In conclusion, vitamin E has antioxidant effects which could be able to antagonize diphenylamine prenatal toxicity.","PeriodicalId":15163,"journal":{"name":"Journal of Bioscience and Applied Research","volume":"20 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-10-24","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"82578352","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

CRC biomarkers are desperately needed for early detection. Traditional CRC tumor markers do not have the best diagnostic performance. The levels of leptin and vitamin D were evaluated. CRC patients before treatment (n=16), CRC patients after treatment (n=14), and 20 patients with benign tumors were included in this case-control study. ELISA was used to determine the levels of traditional tumor markers (CA19.9 and CEA) as well as candidate markers (leptin and vitamin D). Using area receiver-operating characteristic analysis (AUC), the diagnostic performance of single and combination markers was assessed (ROC). The levels of CEA and CA 19.9 in the three groups studied were not significantly different. Vitamin D and leptin were significantly decreased (p= 0.03 and p= 0.02; respectively) in CRC patients than after benign patients. A novel combination, based on the combination of vitamin D and leptin was developed for CRC diagnosis using stepwise multivariate discriminant analysis (MDA). The combination can be represented as = (4.65 – vitamin D ((ng/ml)) × 0.009 + Leptin (ng/ml) × 0.441). AUCs were reported when leptin was used as a single biomarker for distinguishing CRC from benign (0.78) and non-treated CRC from treated CRC (0.67). When leptin and vitamin D were combined, the AUCs increased to 0.84 and0.72, respectively. Conclusion: Leptin and vitamin D were shown to be promising diagnostic and follow-up indicators for CRC in our investigation.","PeriodicalId":15163,"journal":{"name":"Journal of Bioscience and Applied Research","volume":"32 1","pages":""},"PeriodicalIF":0.0,"publicationDate":"2021-09-28","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"87006647","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":0,"RegionCategory":"","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}
