The objective of our study is to highlight the therapeutic effect and mechanism of action by which purified Flaxseed hydrolysate (PFH) which is a lignan rich fraction exerts its anticancer activity on a human breast cancer cell line (T47D) and in mice bearing tumor. HPLC analysis of PFH of six flaxseed cultivars had shown that PFH of the cultivar Giza 9 (PFH-G9) contains the highest concentration of SDG (81.64 mg/g). The in vitro cytotoxic potentiality of PFH's of six flaxseed cultivars was screened against a panel of human cancer cell lines. PFH -G9 showed the most significant cytotoxic activity against ER-receptor positive breast cell lines MCF7 and T47D with IC50 13.8 and 15.8 ?g/ml, respectively. Moreover, PFH-G9 reduced the expression of the metastasis marker, 1-?, metalloproteinases and vascular endothelial growth factor (VEGF), one of the most potent stimulators of angiogenesis, while it increased the caspase-3 dependent apoptosis. Our study also showed that dietary intake of 10% of Giza 9 Flaxseeds (FS), fixed oil (FSO) or Flax meal (FSM) twice daily for 3 weeks in mice-bearing solid Ehrlich ascites carcinoma (EAC) resulted in reducing the tumor volume, the expression of estrogen, insulin growth factor, progesterone, VEGF and MMP-2, but enhanced expression of caspase-3. � 2018 The Author(s).

Flaxseed (Linum usitatissimum L.) is a multipurpose crop with health promoting potential. This study was undertaken to investigate the fatty acid profile and yield of fixed oil of six Egyptian flaxseed cultivars. The selected cultivars with the highest content of polyunsaturated fatty acids (PUFAs) (G9 and G10) were assessed for their antidepressant-like effect in rat model of postpartum depression (PPD) induced by hormone-simulated pregnancy followed by hormone withdrawal and compared to fluoxetine. As compared to control group, administration of G9 and G10 (270 mg/kg/day, p.o) for two weeks during the postpartum period can alleviate anxiety and depressive-like behaviors and biochemical changes in PPD-induced rats. This was confirmed by evaluation of anxiety-like behaviors (elevated plus maze, open field test, and forced swim test tests), in addition to biochemical analysis (brain monoamine oxidase-A, corticosterone level, proinflammatory cytokines, and hippocampal redox state). In conclusion, flaxseed oil of Egyptian cultivars G9 and G10 exhibited significant antidepressant-like effect in rat model of PPD without affecting locomotor activity. At the treatment doses, the antidepressant-like activity of Giza 9 oil is comparable to fluoxetine. � 2017 Nebal El Tanbouly et al.

Background: Flaxseed is a highly important industrial and medicinal plant worldwide. Objective: To use inter simple sequence repeat (ISSR) technique for making unique fingerprint for the four newly produced genotypes of flax in Egypt. Materials and Methods: The genetic diversity among four promising Egyptian flax (Linum usitatissimum L.) genotypes was premeditated by means of polymerase chain reaction-based ISSR markers. The phenotypic variation among the four flax genotypes, namely, promising strains 533/39/5/3 (F1), S.402/3/3/7 (F2), S.421/3/6/4 (F3), and S.11 (F4) was studied during the two successive winter seasons of 2014/2015 and 2015/2016 in randomized complete block design through four replications. Results: The promising strain (F3) surpassed the other flax genotypes regarding seed yield/feddan, oil yield/feddan, and oil percentage. Twelve ISSR primers were used for the genetic examination yielding 139 loci, of which 31 were polymorphic. The middling number of amplified loci and the middling number of polymorphic loci per primer were 11.6 and 2.6, correspondingly, while the percent of loci polymorphism ranged from 0.0% to 58.0% with a middling of 21.4% crosswise all the flax genotypes. The more informative primers were GAC (GATA)4and (GATA)4GC, while the less informative were (AC)8T and (GT)8G. Unweighted pair group method with arithmetic mean derived dendrogram clearly discriminated the flax genotypes in three clusters. The Jaccard's similarity coefficient along with the genotypes ranged from 0.91 to 0.95. Conclusion: This study identified S. 421/3/6/4 (F3) strain to be the mainly assorted genotype and recommended its use in propagation programs and for upward mapping populations.
