Leydig cells are essential for male reproductive development throughout life. Production of androgens as well as intermediate steroids is tightly regulated. Although microRNAs (miRNAs) are suggested to play important roles in spermatogenesis, little is currently known regarding the regulation of steroidogenesis by miRNAs in Leydig cells. Here, we found that miR-150 was predominantly expressed in Leydig cells within mouse testis. Therefore, we determined steroidogenesis of the Leydig cells in which miR-150 was knocked down or overexpressed using miR-150 antagomir and agomir, respectively. Compared with negative control group, a significant increase of STAR expression was observed in miR-150 antagomir-treated Leydig cells. Conversely, STAR expression was significantly reduced in miR-150 agomir-transfected Leydig cells. Production of sex-steroid precursors and testosterone of Leydig cells was also negatively controlled by miR-150. We further identifiedStaras a target of miR-150 using luciferase reporter assay. Finally, we confirmed that miR-150 was necessary for steroidogenesis and spermatogenesisin vivovia intratesticular injection of miR-150 antagomir or agomir. Taken together, our studies suggest that miR-150 negatively regulates the expression of STAR and steroidogenesis of Leydig cells in mice.

Abstract Background: This research was performed to synthesize nanophytosomes-loaded high phenolic fraction (HPF) from Juniperus polycarpos fruit extract and investigate its antiproliferation effects against breast cancer in mice model. Results: The nanophytosomes-loaded HPF from Juniperus polycarpos fruit extract was synthesized. The mice trial was conducted to determine the possible toxic effects of the synthesized nanophytosomes. The anticancer, pro-apoptotic, and antioxidative activities of the nanophytosomes were determined. The nanophytosomes-loaded HPF had a spherical structure with a size of 176 nm and a polydispersity index coefficient of 0.24. The in-vivo study manifested that nanophytosomes-loaded HPF significantly improved weight gain and food intake compared to the negative control group (p<0.05). The nanophytosomes-loaded HPF significantly enhanced the expression of bax (3.4-fold) and caspase-3 (2.7-fold) genes but reduced bcl2 (3.6-fold) gene expression in tumor cells. The average tumor size was significantly decreased in mice treated with nanophytosomes-loaded HPF (p<0.05). The expression of GPX (2.3-fold) and SOD (2.7-fold) antioxidants in the liver of mice supplemented with nanophytosomes-loaded HPF was significantly developed compared to the negative control (p<0.05). The nanophytosomes-loaded HPF did not show toxicity on normal cells. Conclusion: Our results indicated that nanophytosomes-loaded HPF might be a potential anticancer agent for the breast cancer treatment.

Objective: Cobalt nanoparticles (NPs), especially cobalt oxide NPs (Co3O4 NPs) are attracting unique shaped NPs that are used in different biomedical applications and medicine. Different in vitro studies report their toxic and carcinogenic effect but limited in vivo studies were present on its genotoxic potential. The present study was aimed to evaluate the genotoxic potential of Co3O4 NPs on bone marrow cells and sperms and the protective role of omega-3 in male albino mice.Methods: Animals were segregated into four groups that were orally treated for 3 consecutive days, Group 1: Negative control; Group 2: Omega-3 (250 mg/kg); Group 3: Co3O4 NPs (20 mg/kg); and Group 4: Combined group (250 mg/kg Omega-3 and Co3O4 NPs 20 mg/kg).Results: The present results show that Co3O4 NPs administration significantly increased number of micronucleated polychromatic erythrocytes (PCEs)/1000 PCEs, sperm abnormalities, and DNA damage, significantly decreased sperm motility and concentration in comparison to negative control group. However, Omega-3 administration in the combined group modulates the genotoxic potential of Co3O4 NPs in comparison to Co3O4 NPs group.Conclusion: The present study reports the genotoxic potential of Co3O4 NPs in vivo and assesses the protective role of Omega-3 administration due to its antioxidant effect.

The aim of this study is to investigate the antitumor activity of Plantago major L. extract in Ehrlich ascites tumor (EAT) bearing Balb/C mice in vivo. Thirty male Balb/C mice were divided into 5 groups: 3 treatment groups and 2 control groups (6 per group). Treatment groups and the negative control group were injected with EAT (1 × 106 cells) intraperitoneally to develop ascites tumor. P. major L. extract (1%, 2% and 3% concentration extracts, 0.1 ml/day/mouse) were given p.o. for 10 alternate days. The control group was treated with 0.9% NaCl solution (0.1 ml/day/mouse). The changes of body weight in animals were recorded. On the 11th day, all of the mice were sacrified and their tissues were stained with haematoxylen and eosin for pathological studies. Body weights of in 3 treatment groups and the negative control group were elevated because of tumor burden. The maximal weight gain was recorded in the negative control group and the minimal weight gain was recorded in Group I. Pathological studies showed that P. major L. extract (especially 1% concentration) has inhibitive effect on EAT. P. major has an inhibitory effect on EAT in a dose dependent manner.
