Effect of hesperetin on interleukin-8 gene expression in MCF-7 cell line: Short Communication

Breast cancer is recognized as the most common cause of cancer deaths in women. So far, no definite treatment has been identified there is no certain cure for breast cancer. The Ooverexpression of interleukin-8 is associated with increased tumor growth and breast cancer metastasis. Hesperetin is a flavonone sub-group of flavonoids that is abundantly found in citrus fruits, including lemons and oranges. Considering the anti-cancer and anti-inflammatory role of hesperetin, as also, well as the role of interleukin-8 in cancer metastasis and progression, in this studythe present study aimed to assess , the effect of hesperetin on the expression of the interleukin-8 gene in MCF-7 cell line has been investigated. The relative expression level of interleukin-8 gene in MCF-7 cell line at concentrations of 0, 25, 50, 100, and 200 µM hesperetin and durations of 6, 24, and 48 hours (with the concentration of 100 µM) was performed using the A real-time polymerase chain reaction (real-time PCR)Real-time method PCR was performed. The obtained Our results pointed out showed that the level of interleukin-8 gene expression decreases with an increase in by increasing the concentration of hesperetin (up to 100 µM), the level of interleukin-8 gene expression decreases. Furthermore, Also, the level of interleukin-8 gene expression in the 48-hour treatment was lower than that in the 24- and 6-hour treatments. Considering its various properties, including anti-cancer and anti-inflammatory properties, hesperetin could be effective in reducing the risk of metastasis and progression of breast cancer by reducing the expression of the interleukin-8 gene

Association between adherence to a low carbohydrate dietary (LCD) pattern with breast milk characteristics and oxidative markers in infants’ urine: a cross-sectional study

Abstract Background Breast milk (BM) is a dynamic fluid that varies over time and between women. The variations in BM components are most likely associated with maternal diet quality. This study aimed to assess adherence to a low carbohydrate dietary (LCD) pattern with oxidative stress markers of BM characteristics and infants’ urine. Materials and methods In this cross-sectional study 350 breastfeeding mothers and their infants were recruited. BM samples were collected from mothers, and urine specimens were obtained from each infant. To evaluate LCD scores, subjects were divided into 10 deciles according to the percent of energy obtained from carbohydrates, proteins, and fats. Determination of total antioxidant activity was conducted using the ferric reducing antioxidant power (FRAP), 2, 2′-diphenyl-1-picrylhydrazyl (DPPH), thiobarbituric acid reactive substances (TBARs), and Ellman’s assay. Biochemical assays of samples including calcium, total protein, and triglyceride level were also performed using commercial kits. Results Participants with the greatest LCD pattern adherence were placed into the last quartile (Q4), and those with the minimum LCD were in the first quartile (Q1). Individuals in the highest LCD quartile had significantly higher levels of milk FRAP, thiol, and protein, as well as infant urinary FRAP and lower milk MDA levels than those in the lowest quartile. Multivariate linear regression analyses indicated that higher score of the LCD pattern was associated with a higher level of milk thiol, protein, and lower level of milk MDA (p < 0.05). Conclusion Our findings show that adherence to a LCD, as defined by a low level of carbohydrates in daily food intake, is linked with improved BM quality and markers of oxidative stress in infant urine
