Breast cancer is the fourth common cancer worldwide and occurs when breast cells begin to uncontrolled division and tumor formation. Angiogenesis is one of the essential factors in cell growth and maintenance of homeostasis in the natural and pathological conditions, while VEGFs are the most critical factors in angiogenesis. MiR-210 plays an important role in the angiogenesis via association with VEGF. Here, the miR-210 expression changes in response to a VEGFB antagonist peptide, called VEGB1, was studied in female BALB/c mice bearing 4T1 cell line induced breast tumor. The treated group received and of the peptide and the control group received PBS intraperitoneally during two weeks. Both of the animal groups underwent a resection of breast tissue 14 days after treatment and miR-210 expression level was investigated. Statistical analysis by On-way ANOVA showed that the expression level of miR-210 gene had significant differences among the groups treated with various doses of VEGB1. Also, the gene expression was significantly different between peptide-treated groups and control samples (p<0.05). MiR-210 expression level had 42% reduction in mice treated with of VEGB1, while 90% was seen in mice treated with of VEGB1 showing the inhibitory function of VEGB1 antagonist peptide at different doses.

Chickpea is one of the most important plants of the legume family and is very important in the diet. In order to investigate the genetic diversity of chickpea, an experiment was conducted with 18 chickpea genotypes in the form of a completely to investigate the genetic diversity of chickpea, an experiment was conducted with 18 chickpea genotypes in the form of a completely randomized block design. After acclimatization of plants to cold, freezing treatment was applied at temperatures of -6, -8 and -10 and their 50% lethality temperature (LT50) was determined by probit transformation. Before and after the habituation stage, a leaf sample was taken and the relative content of leaf water, photosynthetic pigments, proline, soluble sugar, protein percentage, catalase, peroxidase, polyphenol oxidase and greenness index were measured. Genotype number 5 with the lowest LT50 (-8.86) and the highest survival percentage (80%) was the most resistant genotype and genotype 10 with the highest LT50 (-3.57) and the lowest survival percentage along with genotype 15 were recognized as the most sensitive genotypes. In order to evaluate genetic diversity, DNA extraction was utilized and 21 different ISSR primers were used in the investigation. The results showed the presence of polymorphism among the cultivars studied. A total of 101 clear bands were produced, of which 94 were polymorphic bands. Polymorphic information content (PIC) was in the range of 0.332 (initiator 7) to 0.049 (initiator 16). The amount of gene diversity was between 0.126 and 0.977 changes. Cluster analysis of genotypes was done using Jaccard similarity coefficient and UPGMA method
