Among the human antioxidant mechanisms there are the enzymes catalase (CAT), glutathione peroxidase (GPx) and superoxide dismutase (SOD). Our aim was to measure NF-κB, its inhibitor (IKK) and oxidative stress in placenta and umbilical cord of pregnant women submitted to a supervised nutritional program. Methods: Two groups were conformed: A) 14 pregnant women with individualized nutritional counseling and B) 12 pregnant women without nutritional guidance. NF-κB and IKK were assessed by real time PCR (RT-PCR). Enzymatic activity of CAT, GPx, lipoperoxidation (LPO) and SOD were also evaluated. Results: Pregnant women that followed-up a supervised nutritional program had lower level of systolic (p=0.03) and diastolic pressure (p=0.043) although they were heavier than a control group (p=0.048). Among all women, the Spearman correlation was positive between weight gain and placental NF-κB expression (1, p≤0.01). In placenta, women with nutritional advice had lower enzymatic activity of GPx (p≤0.038) and showed a tendency of IKK to be higher than in women without a nutritional supervised program. Conclusion: A supervised nutritional program in pregnancy offers a proven option to control weight gain, hypertension, NF-κB/IKK complex expression and oxidative stress reactions in placenta. | URI: | http://ri.uaemex.mx/handle20.500.11799/99927 | Other Identifiers: | http://hdl.handle.net/20.500.11799/99927 | Rights: | info:eu-repo/semantics/openAccess http://creativecommons.org/licenses/by-nc-nd/4.0 |
