Bioinformatic Analysis of Circadian Expression of Oncogenes and Tumor Suppressor Genes

Background: Circadian rhythms are physiological and behavioral cycles with a period of approximately 24 hours that control various functions including gene expression. Circadian disruption is associated with a variety of diseases, especially cancer. Although some of the oncogenes and tumor suppressor genes (TSGs) are known as clock-controlled genes (CCGs), the analysis and annotation of circadian expression of most human oncogenes and TSGs are still lacking. This study aims to investigate the circadian expression of a list of human oncogenes and TSGs. Methods: A bioinformatic analysis was conducted on a gene library comprising 120 genes to investigate the circadian expression of human oncogenes and TSGs. To achieve this purpose, the genotranscriptomic data were retrieved from COSMIC and analyzed by R statistical software. Furthermore, the acquired data were analyzed at the transcriptomic and proteomic levels using several publicly available databases. Also, the significance of all analyses was confirmed statistically. Results: Altogether, our results indicated that 7 human oncogenes/TSGs may be expressed and function in a circadian manner. These oncogenes/TSGs showed a circadian expression pattern at CircaDB database and associated with at least one of the circadian genes/CCGs based on both genotranscriptomic and correlation analyses. Conclusions: Although 4 of 7 finally outputted genes have been previously reported to be clock controlled, heretofore there is no report about the circadian expression of 3 other genes. Considering the importance of oncogenes/TSGs in the initiation and progression of cancer, further studies are suggested for the identification of exact circadian expression patterns of these 3 human oncogenes/TSGs

Effects of Pomegranate Juice with and without Aerobic Training on Glycemic Control and Lipid Profile in Women with Type 2 Diabetes

Background and Aim: Type 2 diabetes is a common metabolic disease, which is associated with obesity and inactivity. Plant-based dietary patterns are recommended for the treatment of type 2 diabetes. On the other hand, the effect of aerobic training on the improvement of type 2 diabetes is also highly emphasized. The purpose of this study was to investigate the effects of 2-months of pomegranate juice consumption with and without aerobic training on the levels of HbA1c, fasting blood glucose (FBG), lipid profile in women with type 2 diabetes. Methods: In this study, 58 women with type 2 diabetes who were referred to Tehran Lorzadeh clinic were randomly divided into four groups: control, pomegranate juice, aerobic training, combined pomegranate juice with aerobic training. The aerobic training plan consisted of 2-months and three times per week (training time from 20 minutes to 45 minutes). Three days before and after this interventional study, serum levels of FBG, total cholesterol (TC), triacylglyceride (TG), and low-density lipoprotein (LDL) were measured by colorimetric methods. Results: Results showed that combined pomegranate extract consumption with aerobic exercise training significantly decreased the levels of FBG, HbA1c, and TG in women with type 2 diabetes compared to the control group after the intervention (P<0.01), while TC, LDL-c, and BMI remained unchanged. There was no statistically significant difference in the levels of TC, TG, HbA1c, and FBG in pomegranate extract or aerobic training groups compared to the control group after intervention. Conclusion: The results of this study indicate that combined pomegranate juice with aerobic training has beneficial effects on type 2 diabetes and could be recommended in their therapeutic program. *Corresponding Author: Fariba Mohammadi Tahroodi; Email: [email protected] Please cite this article as: Vaziri Javid R, Safizadeh F, Rastegary M, Nabi Afjadi M, Khonakdar-Tarsi A, Zare Z, Zarpou S, Mohammadi Tahroodi F.

Investigation of the effect of 12-weeks of Pilates training on serum levels of some adipokines in inactive women with overweight

Background: The role of adipokines has been recognized in metabolic settings and obesity-related disorders. Therefore, the purpose of this study was to investigate the effect of 12-weeks of Pilates training on serum levels of some adipokines in inactive women with overweight. Methods: Twenty four accessible healthy overweight women with average BMI of 27.2 ± 1.1 kg/m2 participated in this quasi-experimental study. They randomly divided into two groups: exercise group (n=12) and control group (n=12). Pilates exercise training was performed during 12-weeks (3 sessions per week, 60 min per session). During this period, the control group did not have any exercise activities. Blood samples were taken in two steps 48 hours before and 48 hours after the last session and after 12-14 hours of fasting to measure serum levels of visfatin, chemerin and resistin levels. The dependent t-test was used to examine the within-group changes and covariance analysis was used to examine the changes in between-group changes. Results: The results of this study showed that after 12-weeks of Pilates exercise training, visfatin (P= 0.012), chemerin (P=0.002) and resistin changes (P=0.005) in the training group had a significant decrease in post-test compared to the pre-test, as well as there was a significant decrease in serum visfatin levels (P = 0.035), chermerin (P = 0.018) and resistin (P=0.045) in the exercise group compared to the control group. Conclusion: Based on the results of this study, Pilates exercise training is a stimulus factor for adipokines levels changes in inactive women with overweight. It is probably one of the causes of physiological changes is the activity of adipokines levels

Effects of dietary supplemental chromium methionine, zinc oxide, and ascorbic acid on performance, egg quality traits, and blood parameters of laying hens subjected to heat stress

Based on a 2 × 2 × 2 factorial, the effects of three dietary supplemental including chromium methionine (Cr) (0 and 400 μg/kg diet), zinc oxide (Zn) (0 and 30 mg/kg diet), and vitamin C (VitC) (0 and 250 mg/kg diet) on egg production (EP) and mass (EM) and egg traits in heat-stressed (HS) Lohmann LSL-Lite laying hens from 30 to 45 weeks of age were evaluated. The house temperature was kept at 18°C (weeks 30–40 of age) and then increased to 32°C (weeks 41–45 of age). Dietary treatments had no significant effects on EP, egg weight, EM, and feed conversation ratio before and after exposure to heat stress (P > 0.05). Decreased feed intake intake was observed in group of VitC during exposing to HS (P < 0.05). Dietary supplemental Cr decreased serum glucose concentration before HS (P < 0.05). A combination of Cr and VitC increased serum glucose concentration before and during HS (P < 0.05). Decreased serum concentration of Zn was detected in hens fed the diets with VitC, Cr, or Zn (P < 0.05). Increased serum concentration of Cr was observed in hens fed the diets supplemented with Cr (P < 0.05)

Effectiveness of cognitive-behavioral therapy (CBT) in improving the quality of life and psychological fatigue in women with polycystic ovarian syndrome: a randomized controlled clinical trial

Introduction: Given the increasing prevalence of complications caused by the polycystic ovarian syndrome (PCOS) such as medical and psychological problems and also the chronicity of this disease, patients with the PCOS tend to experience lower quality of life and greater psychological fatigue similar to other patients with chronic diseases. This study was conducted to determine the effects of cognitive-behavioral therapy (CBT) on the quality of life and psychological fatigue in women with the PCOS. Methods: This randomized controlled clinical trial study, conducted from 2016 to 2017, enrolled 74 women aged between 18 and 35 years from the Iranian city of Saqqez. The participants were assigned to a CBT group and a control group via block randomization. The intervention group received 8 weekly CBT sessions between 45 and 60 minutes each. The Polycystic Ovary Syndrome Health-Related Quality of Life Questionnaire (PCOSQ) and the Fatigue Impact Scale (FIS) were completed by the patients before and after the intervention. Results: No significant differences were observed between the two groups before the intervention in terms of sociodemographic characteristics and the mean scores of quality of life and psychological fatigue. After the intervention, the mean (standard deviation [SD]) of the quality of life score was 60.2 (13.3) in the intervention group and 24.4 (15) in the control group, with the mean score of quality of life being significantly higher in the intervention group than in the control group (adjusted mean difference = 33.1). The mean (SD) score of psychological fatigue was 28.2 (13.9) in the intervention group and 78.2 (37.1) in the control group, with the mean score of psychological fatigue being significantly lower in the intervention group than in the control group (−54.8). Conclusions: The results showed that CBT was able to reduce fatigue and improve quality of life in our sample of women with the PCOS and ultimately boost their health
